JOURNAL FREE ACCESSBoth double balloon endoscopy (DBE) and capsule endoscopy (CE) are high diagnostic tools. The most frequent indication for these endoscopies is obscure gastrointestinal bleeding (OGIB), which contains various diagnoses such as vascular disease, ulcers and tumors. High diagnostic yields depend on the early timing of the examination from bleeding. We should assemble the best diagnostic strategy based on the severity of bleeding, the detailed case history and the full knowledge about CE and DBE.View full abstractDownload PDF (1155K)

JOURNAL FREE ACCESS[Purpose]Recently, video capsule endoscopy (VCE) and double-balloon endoscopy (DBE) have been introduced into clinical practice for obscure gastrointestinal bleeding (OGIB). Both are said to be very useful. This study assessed the VCE images and effectiveness of VCE. [Methods]116 patients who had both VCE and DBE for OGIB were enrolled in the study. The diagnosis or findings obtained by VCE were compared to the final diagnosis, and the results and the efficacy of VCE were assessed. [Results]The VCE positive finding rate was 62.9%, but a definitive diagnosis was made in only 13 patients (11.2%) using VCE. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 76.7%, 74.2%, 87.5%, 57.5%, and 76.0%, respectively. The accuracy of VCE diagnosis was around 76%. [Conclusion]It is difficult to make a definitive diagnosis based on VCE findings. However, VCE findings play a “guide role” to the definitive diagnosis.View full abstractDownload PDF (570K)

JOURNAL FREE ACCESSA 62-year-old man had low anterior resection due to advanced rectal cancer 4 years earlier. He subsequently developed a hepatic tumor which was detected on CT and was likely a metastatic lesion. Preoperative gastrointestinal endoscopy revealed an adenocarcinoma (IIa+IIc) at the lesser curvature of the gastric antrum. First, a partial hepatectomy was carried out for the liver tumor, and then, an endoscopic submucosal dissection (ESD) was performed for the IIa+IIc lesion. On histopathology, the liver tumor was diagnosed as a rectal cancer metastasis ; the IIa+IIc lesion in the stomach was diagnosed as a well differentiated adenocarcinoma in the mucosal area and carcinoid (type III) in the submucosal area under the carcinoma. Since the gastric carcinoid and the gastric cancer were separated, even though they ware part of the same lesion, it was thought that they had occurred independently. In the paper, we present a rare cace that type III cartinoid coexisting with gastric cancer and review the literature.View full abstractDownload PDF (3198K) -

JOURNAL FREE ACCESSA 75-year-old man had undergone total gastrectomy with Roux-en Y reconstruction for advanced gastric cancer was admitted to our hospital because of dysphagia on 20 months after surgery. We made a diagnosis of a reconstructed jejunal stenosis due to local recurrence of gastric cancer. This was treated by insertion of a self-expandable metallic stent. After placement of the stent, the patient was able to maintain oral intake without complications for 6 months. SEMS placement would improve a quality of life for selected patients with malignant jejunal stenosis.View full abstractDownload PDF (1044K) -

JOURNAL FREE ACCESSA 73-year-old woman underwent sigmoidectomy for sigmoid colon cancer. Three months later, she had hematochezia. Colonoscopy revealed a elevated lesion 10 mm in diameter on the suture line. Its diameter increased to 30 mm in 1 month. The pathological finding was Group II. Laparotomy was perforemed for prevention of ileus. Laparotomy showed migration of fimbriae of oviduct into anastomosis in the previous sigmoidectomy. Because the anastomosis was performed without any trouble during operation, this migration seems to occur in postoperative course. Migration of fimbriae of oviduct into anastomosis has not been reported in Japan.View full abstractDownload PDF (564K) -

JOURNAL FREE ACCESSA 77-year-old man was abmitted to our hospital for abdominal pain and rectal mass. He had no hematochezia and no lower urinary tract symptoms. Digital examination of the rectum revealed hard mass of the left side of the rectum. CT image of the pelvis showed marked thickening of the rectal wall and slightly enlarged lymph nodes around the sigmoid colon. Colonoscopy revealed small depressed lesions like type 0-IIc colonic cancer at the sigmoid colon and protruded lesion like submucosal tumor at the rectum. Pathological findings showed poorly differentiated adenocarcinoma on both lesions. So we diagnosed colorectal cancer and surgical procedure was planned. But pathologist suggested to us that this lesion might be metastatic prostate cancer. We added measuring of serum prostate specific antigen (PSA) level and immunohistochemical study. Serum PSA was very high (2,162ng/ml) and immunohistochemical staining of PSA was positive. MRI imaging of the pelvis showed no infiltration to the rectum, so he was diagnosed as prostate cancer and colorectal metastasis. Anti-androgen therapy was started immediately. Colorectal involvement/metastasis by prostate carcinoma is rare but endoscopist should aware of this pit fall of differential diagnosis.View full abstractDownload PDF (1195K) -

JOURNAL FREE ACCESSHuman intestinal spirochetosis (HIS) is considered a zoonotic agent. HIS is a common condition in the Western and developing countries, especially in homosexual men and HIV infected patients. HIS have been implicated in the manifestation of bowel symptoms such as purulent discharge, diarrhea, and rectal bleeding. Histopathologicaly, it is characterized by being basophilic and flocculent colonies that adhere to the epithelial surface of the large intestine. We report two cases of intestinal spirochetosis caused by B. aalborgi, which was complicated amebic colitis in Japan.View full abstractDownload PDF (907K) -

JOURNAL FREE ACCESSA 70-year-old man developed abdominal pain. Abdominal CT scan showed fluid collections in the subcapsular space of the liver and around the hepatic flexure of the colon, as well as calcifications similar to gallstones which measured 10 mm in diameter in the ascending colon. A subcapsular liver abscess and an intraabdominal abscess due to acute cholecystitis were diagnosed. Calcifications in the ascending colon were thought to be gallstones from the cholecystocolic fistula. On colonoscopy, a stone-like gallstone in the descending colon and the orifice of the cholecystocolic fistula located at the hepatic flexure were found. The abscess cleared with percutaneous transhepatic abscess drainage and the cholecystocolic fistula closed spontaneously. We report a rare case of the cholecystocolic fistula complicated by a subcapsular liver abscess.View full abstractDownload PDF (813K)

JOURNAL FREE ACCESS[Background/Aims]A wide endoscopic view is required for safe percutaneous endoscopic gastrotomy (PEG). We introduced a new method of transnasal gastroscopy to observe the gastric angle in an inverted position during PEG. Here, we investigated the efficacy of this method.
[Subjects and Methods]We carried out PEG with a transnasal gastroscope in an inverted position (the inversion group) and in a looking-down position (the looking-down group) in 10 patients each. We compared the endoscopic view and maneuverability during PEG and complications between the two groups.
[Results]In the inversion group, the better visualization of the gastric angle including the posterior wall provided easier manipulation of each PEG procedure, as compared to the looking-down group. In the inversion group, no complications were observed, while mucosal hemorrhage from the posterior gastric wall was observed in 2 patients of the looking-down group.
[Conclusions]The inverted position of the transnasal gastroscope is useful to provide better view and manipulation for a safe PEG.View full abstractDownload PDF (643K)

JOURNAL FREE ACCESSFormerly, patients with a past history of gastrectomy or with a history of gastric surgical reconstruction, such as Roux-en-Y reconstruction, were said to be difficult cases for endoscopic evaluation and treatment. Because of this, endoscopic procedures were performed only in limited facilities. Much of the endoscopic precedures were made possible only by the physician's passion and technique. However, after the development of double-balloon endoscopy, it has become relatively easier for physicians to reach the duodenal papilla of post-gastrectomy patients, and as a result, more facilities are reporting ERCP cases performed on post-gastrectomy patients, and also techniques related to ERCP. By using regular upper endoscopy and thin-radius lower tract endoscopy, we were able to reach the duodenal papilla of post-Billroth II reconstruction patients in 87.5% of the cases. We were able to reach the papilla in the rest of the two cases by using the double-balloon endoscopy. Papillary procedures were possible in all of the cases where the duodenal papilla was reached. In three cases of post-Roux-en-Y reconstruction patients, we were able to reach the duodenal papilla in all cases by using the double-balloon endoscopy. However, papillary procedure was not possible in one of the cases. We were able to reach the papilla in all three post-PD patients with choledochojejunostomy reconstruction with regular upper tract endoscopy. In performing ERCP and EST in post-gastrectomy patients, it is the utmost importance to obtain information about the reconstruction method, but we have taken up the techniques related to reaching the duodenal papilla in this presentation.View full abstractDownload PDF (1327K)

JOURNAL FREE ACCESSProximally migrated biliary plastic stent and migrated stent in the pancreatic pseudocyst are relatively rare complications. A migrated stent causes poor drainage conditions, which leads to secondary complications such as infection, abscess, perforation and, moreover, becomes a foreign object in the body, and retrieval or re-stenting is therefore necessary. The retrival of a migrated stent includes surgical, percutaneous and endoscopic approaches, and the most non-invasive method is endoscopic retrieval. However, because very few devices are exclusively designed for retrival, the current situation is that the available devices are used while taking advantage of various ideas and techniques. From previously reported cases and our experiences of such cases, we herein describe the methods of endoscopic retrieval for stents that have migrated into a bile duct or pancreatic pseudocysts.View full abstractDownload PDF (778K)
