A 40s-year-old man was admitted to our hospital owing to severe general fatigue with blood pressure lowering. He was diagnosed with diabetic ketoacidosis as the laboratory examinations revealed hyperglycemia and metabolic acidosis. An esophago-gastro-duodenoscopy (EGD) was performed on the third day of the illness due to suspected upper gastrointestinal bleeding. Since the EGD showed circumferential blackening and white moss-like adhesions in the lower esophageal mucosa, he was diagnosed with acute necrotizing esophagitis. He was kept fasting, and was administered proton pump inhibitors and high-calorie infusions. The clinical course was good; he resumed eating on day 20 and was discharged on day 37.

We herein report a rare case of esophageal carcinoma with giant intramural metastasis to the stomach. Endoscopy revealed a 71-year-old man with deglutition disorder to have a lesion in the middle esophagus and a giant submucosal tumor about 60 mm in diameter in the gastric cardia with erosion on its top. Histopathologically, the tumor was shown to be moderately differentiated squamous cell carcinoma, so we diagnosed him with esophageal carcinoma with intramural metastasis to the stomach. Chemoradiation therapy was administered given to prevent regional recurrence, A complete response was achieved, and this patient remains alive without recidivation at 10 months.
In the past, there have been a few cases in which gastric lesions were diagnosed as intragastric metastasis before surgery, and as a result regarding the diagnosis of gastric submucosal tumor, many cases were diagnosed as intragastric metastasis only by surgery. This is a rare case of esophageal carcinoma with giant intramural metastasis to the stomach that has been successfully treated with chemoradiation therapy; thus, we report this case along with a discussion.

A 91-year-old woman was admitted for rehabilitation after undergoing right total knee arthroplasty. Her oral intake was poor after hospitalization, and she experienced vomiting on the 13th day of the disease. Abdominal computed tomography showed mesenteroaxial gastric volvulus with a giant esophageal hiatal hernia, and she underwent endoscopic repair under X-ray fluoroscopic guidance. However, her oral intake did not improve following treatment secondary to gastric volvulus recurrence. She refused surgical intervention owing to her advanced age, and we performed percutaneous endoscopic gastropexy using a Funada-style loop gastropexy device. Her postoperative course was uneventful, and oral intake was gradually resumed without recurrence of gastric volvulus. Percutaneous endoscopic gastropexy may be a useful, less invasive treatment option in patients with gastric volvulus who are at high risk for surgery.

A 70s man admitted to our hospital with a gastric abnormality. Esophagogastroduodenoscopy showed submucosal tumor-like lesion, approximately 25 mm in diameter, on lesser curvature of middle corpus of the stomach and depressed lesion on the top of the elevation. Biopsy specimens indicated well-differentiated tubular adenocarcinoma. Endoscopic ultrasonography (EUS) revealed multiple heterotopic gastric glands mainly in the gastric submucosa, which were diagnosed diffuse cystic malformation (DCM). We performed endoscopic submucosal dissection (ESD) for early gastric cancer based on DCM. DCM frequently causes gastric cancer, but DCM makes it difficult to diagnose the invasion depth by conventional endoscopy. Consequently EUS is important in deciding the treatment strategy for gastric cancer with DCM. Careful follow-up observation is necessary in consideration of the occurrence of metachronous gastric cancer because cancer often occurs frequently.

A 64-year-old woman visited a nearby hospital complained of stomachache. EGD showed atrophic gastritis due to Helicobacter pylori infection and a submucosal tumor in the greater curvature of the antrum. Her symptoms was not improved due to eradication for H. pylori infection, therefore, she was introduced to our hospital. EGD revealed the submucosal tumor with erosion and oozing 2 cm in diameter. Hemostasis was conducted. Endoscopic ultrasonography (EUS) showed hypoechoic tumor with aechoic area in the submucosal layer. Histopathological findings of biopsy specimens showed regenerated epithelium.
Because of rebleeding, she underwent laparoscopic gastric local resection. Histopathological findings revealed a large number of fibroblasts with eosinophilic infiltration, and she was diagnosed with gastric inflammatory fibroid polyp (IFP).
Gastric IFP is a benign submucosal tumor and bleeding is rare. We reported the rare gastric bleeding IFP with bibliographical consideration.

A 69-year-old woman visited our hospital for gastric abnormality in the upper gastrointestinal series. She had no subjective symptoms. Blood examination including tumor marker revealed normal levels. A gastrointestinal endoscopic study revealed a stage 0-IIc-like lesion of the stomach body. Histological findings of the biopsy specimen revealed gastric carcinoma with lymphoid stroma on hematoxylin and eosin staining, and the tumor cells were positive for the in situ hybridization of Epstein-Barr virus (EBV) -encoded small RNAs. Enhanced computed tomography images revealed no metastasis to lymph nodes and other organs in the chest and abdomen. Therefore, the diagnosis was gastric carcinoma with lymphoid stroma-associated EBV (clinical stage IA), and surgery was performed. The frequency of EBV-associated carcinoma is not small and it has poor subjective symptoms; hence, its discrimination by characteristic clinical pathology findings is necessary.

A 34-year-old man visited my clinic for the symptoms of GERD. He has allergies including food and had a dog as a pet.
Upper gastrointestinal endoscopy revealed nodular mucosa in the gastric antrum and the presence of linear furrows and bamboo-joint like appearance throughout the esophagus. In blood biochemistry, IgE RAST of crustacea was positive; H. pylori IgG antibody and Urea Breath Test were negative.
Histopathological findings showed eosinophil infiltration of more than 40 / HPF in the esophageal mucosa and chronic active gastritis with lymphoid follicles with large helical bacilli with Gimenes staining. He was diagnosed with H. heilmannii-like Organism (HHLO) nodular gastritis accompanied by eosinophilic esophagitis (EE). He was prescribed oral proton pump inhibitor and fluticasone inhalation which resulted in improvement of endoscopic and histologic findings.
Reports of HHLO nodular gastritis accompanied by EE are rare. Therefore, this case is considered to have some clinical significance in H. pylori negative era.

A 76-year-old male was scheduled for gastric endoscopic submucosal dissection (ESD) of early-stage gastric cancer. During the ESD procedure, hypoxemia caused by laryngeal edema occurred and ESD was discontinued. Emergency tracheal intubation was attempted but it was difficult due to the presence of a large epiglottic cyst. Using a McGRATH laryngoscope, tracheal intubation was managed successfully. He was treated with steroids for laryngeal edema, and was discharged to home without any sequelae. An epiglottic cyst is a risk factor for difficult intubation. In patients who are scheduled for upper endoscopic treatment that requires sedation, a large epiglottic cyst should be removed before treatment.

A 47-year-old man complained about chronic epigastric pain. He underwent upper gastrointestinal endoscopy, revealing a 20-mm smooth, cushion sign-negative SMT in the greater curvature of the stomach. Endoscopic ultrasonography (EUS) revealed a low echogenic mass from the 4th layer, which was heterogeneous in the inside. EUS and abdominal computed tomography after 1.5 year showed a tendency to increase to 25 mm. Neuroendocrine tumor (NET) G1 was diagnosed by EUS-FNA, laparoscopic gastrectomy was performed, and glomus tumor was diagnosed by pathological analysis. Primary gastric glomus tumors are rare and need further study with a literature review.

A woman in her seventies presented with multiple polyps in her stomach, and a polyp in the lower gastric body was diagnosed pathologically as Group 4, borderline malignancy. Helicobacter pylori was eradicated as an alternative to gastrectomy, and the lesion disappeared morphologically and histologically 10 months after eradication. However, after 28 months, advanced gastric cancer suddenly appeared at a site different from that of the borderline malignancy lesion. Gastrectomy was performed, and the gastric cancer was diagnosed as a poorly differentiated adenocarcinoma. Most of the polyps were diagnosed as foveolar hyperplastic gastric polyps, but a few polyps were diagnosed as Peutz-Jeghers-type hamartomatous gastric polyps, which were histologically characterized by distinctive arborization of smooth muscle within the lamina propria. The patient was diagnosed with a solitary gastric Peutz-Jeghers-type polyp because she had Peutz-Jeghers-type hamartomatous polyps without family history, mucocutaneus pigmentation, and intestinal polyposis and did not meet the diagnostic criteria of Peutz-Jeghers syndrome. A solitary gastric Peutz-Jeghers-type polyp is very rare, and a high frequency of cancer complications has been reported; thus, careful observation for cancer screening is required.

The patient was a 66-year-old man with a history of hepatitis B, hepatocellular carcinoma, and early-stage esophageal cancer. Although gastric submucosal tumor in the greater curvature of the upper stomach was suspected at upper gastrointestinal endoscopy over 10 years ago, biopsy was not performed because of unchanged tumor size and morphology. Endoscopy performed 1 year before visiting our hospital revealed the morphology of a submucosal tumor, which transformed to a type 3 lesion the following year. Moderately-to-poorly differentiated adenocarcinoma (stage I, T2N0M0) was diagnosed with biopsy, and open total gastrectomy with D2 lymph node dissection was performed.
The histopathology revealed moderately differentiated tubular adenocarcinoma and non-solid-type poorly differentiated adenocarcinoma with regional lymph node metastasis. The final diagnosis was stage IIIA (T4aN2M0), and outpatient chemotherapy is currently being administered.
Endoscopic ultrasound-guided fine-needle aspiration should be actively performed even for gastric submucosal tumors with no morphological changes.

The case is A 63-year-old man. He visited our emergency outpatient clinic for headache and dizziness in 201X. CT examination was performed, and a diagnosis of left renal cell carcinoma, brain metastasis, multiple lung metastasis, and mediastinal lymph node metastasis was confirmed.He was treated in the urology department.He was referred to our department because of Progression of anemia during treatment for 201X+5 years.
Esophagogastroduodenoscopy (EGD) revealed a submucosal tumor, mainly immediately below the gastric cardia, and a biopsy was performed. Renal cell carcinoma was confirmed by histology, and the patient was diagnosed with gastric metastasis of renal cell carcinoma. Transcatheter arterial embolization (TAE) was performed to prevent rebleeding, and the follow-up EGD showed apparently tumor shrinkage. We report a case in which TAE was performed for gastric metastasis of renal cell carcinoma.

The incidence of gastric cancer after eradication of Helicobacter pylori (HP) is expected to increase in the future. Although reports of early gastric cancer after the eradication account for the majority of cases, scirrhous gastric cancer is rare. Herein, we report three cases of scirrhous gastric cancer after eradication of HP. Case 1: A 50-year-old woman had been treated with eradication of HP and was followed up by esophagogastroduodenoscopy (EGD) on a regular basis. Two years after the eradication, EGD revealed advanced type 4 gastric cancer. Case 2: A 50-year-old woman had been treated with eradication and was followed up by EGD on a regular basis. Twenty-four years after the eradication, EGD revealed advanced type 4 gastric cancer. Case 3: A 50-year-old man had been treated with eradication and was followed up every year by EGD. Five years after the eradication, EGD revealed advanced type 4 gastric cancer. Despite performing regular EGD, cases of scirrhous gastric cancer can be found after eradication. We report our encountered cases, along with relevant literature.

An 80-year-old woman presented with an asymptomatic, painless lump in the right breast. Positron emission tomography incidentally revealed a 45 mm × 25 mm-sized, dumbbell-shaped mass in the epigastric region. Abdominal computed tomography showed that the mass was adjacent to both the stomach and the small intestine. Endoscopic ultrasonography (EUS) showed that the hypoechoic mass had a 1.6 mm-diameter stalk attached to the 4th layer of the gastric wall. Laparoscopic partial gastrectomy was performed. The gastric mass with a narrow stalk was resected and was confirmed as GIST of the stomach histopathologically. The stalk of this tumor was composed of smooth muscle tissue without tumor cells. The diameter of the stalk was 1.6 mm on EUS, and 2.2 mm on histopathological examination. We believe that in vivo in some extra-luminal pedunculated gastric GISTs the stalk may become longer and thinner as the GIST grows.

A 50-year-old woman underwent an esophagogastroduodenoscopy, which revealed a 7 mm submucosal tumor on the greater curvature of the upper gastric body. A biopsy was performed and the tumor was diagnosed as a granular cell tumor (GCT). The patient was then referred to our hospital. Endoscopic ultrasonography revealed a homogeneous low echoic tumor in the 2nd-3rd layer. An endoscopic submucosal dissection (ESD) was performed and the tumor was resected en bloc. Histopathological diagnosis was a benign GCT. The treatment of GCT of the stomach is still controversial, because of its rarity. Malignant GCT of the stomach has been reported, so we must consider the removal of tumors. ESD could become a treatment option after preoperative detailed examination.

A 84-year-old male patient complained of epigastric pain and fever. A computed tomographic (CT) scan revealed thickening of the stomach wall, and an increased peripheral fat tissue concentration, which was suspected to be caused by gastric cancer. The next day, an upper gastrointestinal endoscopy A type 2 lesion was found in the stomach. The abdominal pain worsened, and CT was repeated. Fluid retention was observed in contact with the tumor, and gastric perforation was suspected. Surgical findings showed a large number of abscesses in the wall. The pathological diagnosis was gastric endocrine cell carcinoma. Endocrine cell carcinoma of the stomach is a rare disease, and the prognosis is poor. In this report, we describe a rare intramural abscess associated with gastric endocrine cell carcinoma and review the related literature.

Woman in her fifties. She had been received regularly an upper gastrointestinal endoscopy noted for gastric polyp for several years. Biopsy sample from the polyp was suspected malignancy, so she was referred to come our hospital for examination. Blood examination revealed anti-parietal cell antibody positive, hypergastrinemia and anti-Helicobacter pylori antibody negative. She had severe atrophic gastritis in the body and fundus, but no atrophic gastritis in the antrum. Based on the above, we diagnosed autoimmune gastritis (AIG). We also detected hyperplastic type polyp in anterior wall in the middle body. Magnify endoscopy revealed hyperplastic change and abnormal vessel in the polyp. Afterward we conducted endoscopic mucosal resection (EMR) for the polyp, which was pathologically diagnosed as well-differentiated adenocarcinoma was diagnosed pathologically from EMR sample. It was reported that the risk of cancer in hyperplastic type polyp in AIG was high. We will have to check H. pylori infection but also AIG about gastric hyperplastic type polyp with atrophic gastritis.

An 83-year-old female who presented with vomiting was diagnosed with stenosis from the duodenal bulb to the gastric antrum caused by unresectable pancreatic ductal adenocarcinoma. A self-expandable metal stent (SEMS) was placed under endoscopy at the obstructed region. Following discharge, she underwent 7 courses of gemcitabine+nab-paclitaxel chemotherapy as an outpatient. She developed abdominal pain 205 days after SEMS placement, and abdominal computed tomography revealed intraperitoneal free gas. Emergency laparotomy was performed for a diagnosis of upper gastrointestinal perforation. The patient regained capacity to take food after surgery, and was released on postoperative day 46. The present case is an example of perforation occurring after placement of a metallic stent, a rare complication. We report our experience in a case with late onset of perforation, while also reviewing the literature.

A 59-year-old woman underwent esophagogastroduodenoscopy as a health check-up, which revealed a submucosal tumor-like lesion with a central recess, measuring 20 mm in diameter, on the opposite side of the major duodenal papilla. A biopsy specimen revealed an atypical gland. Although endoscopic ultrasound showed that the tumor may be submucosal invasive cancer, we performed endoscopic submucosal dissection (ESD) due to her lung cancer. Histopathological examination of the tumor showed intramucosal adenocarcinoma (pap>tub1) without vascular and lymphatic invasion. Immunostaining of the tumor revealed positivity for MUC5AC and MUC6, and negativity for CD10 and MUC2, indicating the gastric phenotype. No recurrent cancer has been observed one year after ESD. Endoscopic therapy for early duodenal cancer of the gastric phenotype might lead to the improved prognosis of the patient.

A 60-year-old woman visited our department with the chief complaint of repeated nausea and abdominal pain. Abdominal contrast-enhanced computed tomography revealed circumferential jejunal wall thickening and dilatation of the oral end of the intestinal tract. Therefore, under the diagnosis of small intestinal ileus, she was hospitalized. Small intestinal endoscopy revealed a circumferential ulcerative lesion in the upper jejunum 14 cm from the ligament of Treitz. Biopsy revealed an adenocarcinoma, which led to the diagnosis of small intestinal cancer. No apparent metastasis was observed. Partial resection of the small intestine was performed. The pathological diagnosis was adenocarcinoma tub 2, 50×29 mm, T3 (SS) N0 M0 stage IIA. Postoperative adjuvant chemotherapy was not performed, and the patient has had no recurrence.

Intestinal arteriovenous malformations (AVMs) are an important cause of gastrointestinal bleeding. However, diagnosis is difficult depending on the timing of the examination. [Case] An 86-year-old man complained of bloody stool. Small intestinal capsule endoscopy (CE) revealed a submucosal tumor (SMT) -like elevation in the jejunum. Single-balloon enteroscopy (SBE) did not identify any lesions. Transfusion improved anemia, but gastrointestinal bleeding was observed again. Ninty-four days after the initial CE, small intestinal CE was performed again and revealed an SMT-like bulge with active bleeding in the jejunum. SBE revealed an SMT-like bump with redness in the jejunum, which was considered to be the source of hemorrhage. Small intestinal AVM was diagnosed. Partial resection of the small intestine was performed at a later date.

A 78-year-old female with a bleeding elevated lesion in the sigmoid colon was referred to our hospital. Therefore, endoscopic mucosal resection (EMR) was performed. The pathological diagnosis was pyogenic granuloma. Despite the positive margin, further treatment was withheld because of the absence of hematochezia. After 3 months, she complained of hematochezia. Colonoscopy revealed an elevated lesion on the scar. We performed EMR using a ligation device. The pathological diagnosis was recurrence of pyogenic granuloma and positive margin. After 3 months, colonoscopy revealed a red area on the scar. Biopsy led to the pathological diagnosis of pyogenic granuloma. We performed follow up because the size was small and there was no bleeding. It is important to differentiate pyogenic granuloma from hematochezia, and an appropriate method is required for complete resection.

An 81-year-old woman presented to the Emergency Department complaining of abdominal pain and anorexia ongoing for 3 days. Abdominal contrast CT scan showed intussusception of the small intestine into the transverse colon, with adipose tissue at the lead point. After first performing emergency reduction by colonoscopy, we used single-balloon small-bowel endoscopy to snare and remove the lipoma. Adult-onset intussusception is relatively rare, accounting for only 5% of all cases. While malignant tumors are often the cause of colon intussusception, small intestine cases are more frequently caused by benign tumors. There have been many reports of small intestinal intussusceptions caused by lipomas like in this case, but no cases in which polyp resection was conducted in addition to endoscopic reduction have been reported yet. The choice to treat intussusception by endoscopy is made when surgery is difficult or unnecessary.

We report a case of small intestinal ulcer with active bleeding stopped by colonoscopy.
The 87-year-old man with a history of angina, taking aspirin and clopidogrel was referred for bloody stool. He was suspected of having small intestinal bleeding because of extravasation in the oral side of the terminal ileum on computed tomography, and emergency colonoscopy was performed. Small intestinal Dieulafoy's ulcer with active bleeding was detected, which was stopped by the clip method. Post-endoscopic hemostasis was uneventful. He have passed without recurrence to date.

Olmesartan has recently been reported as a cause of drug-induced enteropathy characterized by chronic diarrhoea and duodenal mucosal atrophy demonstrating sprue-like enteropathy. 82-year-old, male presented to our hospital because of chronic severe watery diarrhea without abdominal pain or fever. Blood examination showed mild anemia (Hb 11.2 mg/dl). Abdominal contrast-enhanced computed tomography showed mucosal edema in the large intestine. Esophagogastroduodenoscopy showed no villous atrophy in the duodenum with the possibility of pyloric gastrectomy, however, colonoscopy showed villous flattering in the terminal ileum and edematous changes in sigmoid colon. Histopathologic examination in biopsy samples from the terminal ileum and sigmoid colon showed interstitial lymphocytic infiltration. He was treated with olmesartan for hypertension at least two years before the onset of symptoms. In addition, watery diarrhea improved soon after discontinuation of olmesartan. Therefore, he was diagnosed as olmesartan-induced enteropathy. Its pathogenesis remains unclear; however, olmesartan-induced enteropathy must be included in the differential diagnosis for patients with chronic diarrhea after the intake of olmesartan.

There are various causes of hematochezia, among which diverticulum hemorrhage is a pathological condition that is often encountered in the clinic and often occurs repeatedly. Therefore, if a patient who has a history of diverticulum hemorrhage presents with hematochezia, conservative treatment is usually administered based on the assumption that the patient has diverticulum hemorrhage and in many cases endoscopy is not performed. We experienced an 85-year-old patient who developed melena three times and whose cause of melena the first time was diverticulum hemorrhage but whose causes of melena the second and third times were different. Just because it is the same symptom in the same person, the cause is not necessarily the same. It is thought that performing endoscopy immediately after melena, taking into consideration various possibilities, is always useful for finding the cause of hematochezia and hemostasis.

A 50-year-old female was referred to our hospital for examination and treatment of a rectal tumor. A colonoscopic examination revealed a 20-mm-diameter, laterally spreading, granular-type tumor in the lower rectum. A conventional image showed a villous tumor in the middle area and narrow-band imaging (NBI) showed a Japan NBI Expert Team type-2A tumor. The biopsy specimen was interpreted as well-differentiated tubular adenocarcinoma. No endoscopic findings suspicious of advanced rectal cancer were obtained; therefore. we planned to perform endoscopic submucosal dissection. However, computed tomography (CT) and magnetic resonance imaging showed multiple enlarged mesorectal lymph nodes. Therefore, a laparoscopic low-anterior resection with lateral pelvic lymph-node dissection was performed. A histological examination showed rectal cancer of por>tub, pT3 N3 M0, and pStage IIIc. The patient rejected adjuvant chemotherapy, and multiple liver and lymph-node metastases were detected at 3 months postoperatively. Although systemic chemotherapy was started, the patient died of cancer 9 months postoperatively.

A 76-year-old woman admitted to our hospital with a positive test for fecal occult blood. Colonoscopy revealed a reddish 20 mm-sized polyp with a nodule in the transverse colon. The nodule partially contained a vessel pattern of JNET type 2B. Therefore, we conducted endoscopic mucosal resection (EMR) for diagnosis and treatment. The specimen led to a diagnosis of inflammatory fibroid polyp (IFP) based on predominantly of eosinophils and onion skin pattern. IFP is an inflammatory lesion arising from the submucosal layer. It is commonly found in the stomach or small intestine, but rarely in the colon.

A 54-year-old woman was referred to our hospital for continuous abdominal pain and melena lasting for 2 weeks. Blood examination results were normal. We performed a colonoscopy and observed a tumor of 30-mm diameter with ulcers and bleeding on the surface. Computed tomography showed low absorption densities of lesions larger than 30 mm. Magnetic resonance imaging of the tumor showed high signal intensity on T1-weighted images, iso-signal intensity on T2-weighted images, and low signal intensity on fat-suppressed T2-weighted images. We performed laparoscopic sigmoidectomy, and the tumor was histopathologically diagnosed as a lipoma. A colonic lipoma is a benign nonepithelial tumor, which is relatively rare in clinical practice.

Although intestinal intussusception is relatively common in children, it remains a rare clinical entity in adults. We report a case of an 84-year-old woman who had mild diarrhea for 6 months. Further examination was performed. Ultrasonographic examination revealed the multiple concentric ring sign in her right flank. Colonoscopic examination revealed a pedunculated tumor with small nodular surface in the ascending colon from the cecum. The histopathological findings were consistent with the diagnosis of a carcinoma in adenoma. Computed tomography revealed the target sign in the transverse view, and invaginated mesenteric fat and associated vessels in the coronary view. She underwent laparoscopic ileocecal resection. The resected specimen revealed a round, pedunculated tumor with a small nodular surface, measuring 55×45 mm in size, in the cecum. The histopathological findings showed well differentiated tubular adenocarcinoma invading the mucosa. She is currently undergoing regular follow-up.

A 51-year-old man presented to our hospital with complaints of blood in his stool and abdominal pain. Contrast-enhanced computed tomography scanning revealed thickening of the rectal wall and dilatation of the oral colon. The patient was diagnosed with obstructive rectal cancer. Retrograde bowel drainage was performed. Subsequently, he relapsed colonic obstruction and ileostomy was performed. Following lower anterior resection and adjuvant chemotherapy, stoma closure was scheduled. However, colonoscopy revealed colon stenosis caused by obstructive colitis from the transverse colon to the descending colon. Balloon dilatation was performed twice; however, adequate improvement was not noted in the colon stenosis. Local injection of a steroid was performed immediately following balloon dilatation. The colon stenosis improved after four balloon dilatations and two local steroid injections. Eventually, stoma closure was performed and his postoperative course was favorable.

A 74-year-old man presented to our hospital complaining of a sensation of retained feces. Colonoscopy revealed a rectal cancer. After preoperative chemoradiotherapy, laparoscopic Miles' operation was performed. On postoperative day 6, the patient complained of abdominal pain around the stoma. Contrast-enhanced computed tomography scanning revealed a low-density area with an air-fluid level near the descending colon. Intraperitoneal abscess resulting from the perforation of the descending colon diverticulum was diagnosed, and percutaneous abscess drainage was performed. However, the fistula persisted. Indigo carmine was injected into the drainage catheter and the perforated diverticulm was identified. The fistula was closed using three short clips. After the clipping, there was no liquid discharge from the drainage catheter. The patient was discharged on postoperative day 56.

The case is a 52-year-old man. He was admitted to our hospital with colonoscopy (CS) showing appendiceal swelling and increasing lesions over time. Contrast-enhanced computed tomography (CT) showed a 10 mm-sized mass lesion which was originated from cecal wall. CS showed a elevated lesion on the appendix with a smooth surface of 10 mm in size and covered by normal mucosa. Endoscopic ultrasonography (EUS) revealed the lesion as a 13 mm-sized cystic lesion, and the inside was dense with fine spotty echoes. No nodules or papillae were found inside. Based on the above, appendiceal mucous cystadenoma was suspected, and laparoscopic partial cecal resection was performed. The final pathological diagnosis was a WHO-classified low-grade appendiceal mucinous neoplasm.
We report a case of appendiceal mucous cyst diagnosed using EUS and undergoing laparoscopic resection.

The patient was a 66-year-old woman who had not been to the hospital or taking any medication. She visited our hospital with chief complaints of fever, headache, and general malaise. Blood tests showed an abnormally high inflammatory response. Chest, abdominal, and pelvic plain CT did not reveal any obvious abnormalities that could cause inflammation.
Streptococcus bovis was detected in blood cultures. Because of the high incidence of colorectal lesions related with the bacterium, a lower gastrointestinal endoscopy showed an advanced colonic cancer in the ascending colon. A laparoscopically assisted right hemicolectomy was performed.
It is a rare case of advanced colorectal cancer discovered by bacteremia caused by S. bovis.

A 66-year-old male with positive fecal occult blood test underwent conventional colonoscopy, which revealed a 10 mm 0-Is lesion with a slightly depressed area in the sigmoid colon. Three days later, the second endoscopic examination revealed that the depressed area had developed well-demarcated and deeper, and microsurface structure could not be evaluated due to erosion on the depressed surface. However, the conventional images and morphological changes of the lesion strongly suggested T1b colorectal cancer with rapid growth. Fourteen days after detection, just before the laparoscopic surgery, the third examination revealed that the depressed area had become much deeper with increased thickness of the elevated margin, and a VI high-grade pit pattern was observed on the depressed surface with exposure of the submucosal cancer mass. Histological examination revealed submucosal massive invasion (2800 μm) of moderately differentiated tubular adenocarcinoma and lymph node metastasis (N1). Some T1b cancers develop rapid morphological changes in a short period of time. In those cases, we should perform surgery even for T1b cancers as soon as possible.

A 27 year-old male was admitted to our hospital because of having bloody stool and diarrhea. Serum hemoglobin level was 7.9 g/dl. Because of bloody stool as anemia progressed, so he underwent colonoscopy. Endoscopy showed of ulcer in the ileocecal valve, it had bleeding point. Endoscopic hemostasis was performed for the vessel using Argon Plasma Coagulation (APC). After endoscopic procedure, he had no bloody stool and anemia was improved. Hemoglobin level recovered to 10 g/dl. Campylobacter jejuni was detected by the cultivation for the stool. So we used for the patient the antibiotic to Fosfomycin Calcium Hydrate for a couple of the days. On the basis of literature, endoscopic procedure is not necessary for campylobacter colitis. However, when bloody stools continues and values of hemoglobin decrease, colonoscope may be recommended as therapeutic option for enterocolitis.

A 66-year-old man visited our hospital complaining of anorexia and hair loss. Upper gastrointestinal endoscopy revealed polyposis with redness throughout the gastric mucosa. Colon scopy also showed polyposis over the entire colon and was complicated by sigmoid colon cancer. On pathological examination, mucous lamina propria was accompanied by cystic dilation of the gland, mucosal edema, inflammatory cell infiltration, and it was a diagnosis of hamartomatous polyps. Based on the above, the patient was diagnosed with Cronkhite-Canada syndrome complicated with colon cancer. Steroid treatmet was started after surgical treatment for colon cancer. After the start of steroid treatment, gastrointestinal tract lesons, alopecia and anorexia was improved. Since steroid treatment was gradually reduced and remission was made, steroid treatment was terminated. However gastrointestinal tract lesions and alopecia worsened, steroid treatment was resumed, and treatment is continued now. Discontinuation and low-dose maintenance of steroid in treatment of CCS have not been clarified in previous studies.
This case report may indicate that the maintenance treatment with low-dose steroid is nessesary for remission of CCS.
