JOURNAL FREE ACCESSIn Japan, the number of obese patients has been gradually increasing, and the morbidly obese patients who are refractory to conventional therapies such as diet and behavior therapy are also increasing year by year. Now, endoscopic intragastric balloon placement and laparos-copic bariatric surgery have been generally performed as endoscopic treatments for morbid obesity in the world. The intragastric balloon placement which has become a safe therapy can induce the weight loss of 12-15 kg for six months and improve comorbidities such as diabetes and hypertension. Laparoscopic adjustable gastric banding which is one of the typical laparos-copic bariatric operations can also reduce the weight and improve the comorbidities more certainly. Although both procedures will be popular in the field of treatments for Japanese obese patients in the near future, the collaboration of bariatric physicians and endoscopists including endoscopic surgeons is essential.View full abstractDownload PDF (6178K) -

JOURNAL FREE ACCESSEGD is conventionally performed transorally. Many patients are reluctant to undergo peroral EGD, however, due to nausea and throat discomfort. Transnasal EGD has a high rate of successful introduction, with a lower incidence of nausea, but also has problems with nasal pain and epistaxis. Nasal pain is usually mild, and the incidence of epistaxis is low, so transnasal EGD is a safe and feasible alternative. At present, the transnasal method is only suitable for diagnostic EGD because the narrow instrument channel does not allow the use of instruments required for therapeutic procedures. In the future, transnasal EGD will be used increasingly in screening for gastric cancer and for routine health checks, as well as a wide variety of clinical applications, in the insertion of ileus tubes, the production of percutaneous endoscopic gastrostomies (PEG), and in endoscopic submucosal dissection (ESD).View full abstractDownload PDF (10300K) -

JOURNAL FREE ACCESSWe report two cases of rapidly developing endocrine call carcinoma (ECC) of the stomach and review 100 (including our two) ECC cases, that have been reported in the Japanese medical literature. Case 1. A 76-year-old male patient had an enlarging lesion in the esophagogastric junction that had grown from 5 mm to 20 mm in diameter over a two months period. On histopathology of a specimen obtained by polypectomy ECC was diagnosed. Thus, the patient had a gastric f undectomy and postoperatively has survived for 15 months to date. Case 2. In a 75-year-old male patient, small erosion in the antrum of the stomach was noted on upper GI x-rays. Over 9 months, it grew to a IIa + IIc type, 18 x 17 mm early gastric cancer. The patient had a distal gastrectomy. In these two cases, diagnosis of ECC was based on immunohisto-chemistry. The incidence of stomach ECC is relatively low, and the prognosis appears to be very poor due to its rapid growth and invasiveness. The preoperative diagnosis of this disease is quite difficult ; in the Japanese medical literature there are very few cases that have been preoperatively diagnosed as ECC. Since, in general, ECC has an aggressive course, it would be preferable to diagnose stomach ECC early and to base the diagnosis on immunohistochemical data.View full abstractDownload PDF (9345K) -

JOURNAL FREE ACCESSA 51-year-old woman, with the diagnosis of pseudomyxoma peritonei, was referred to us for further evaluation of intestinal obstruction. Barium swallow showed a stricture of the distal stomach with complete obstruction. Endscopically no tumor invaded the mucosa on the stricture. Computed tomography of abdomen revealed that stomach was compressed by tumor and there was no obstruction in the small intestine and cob-rectum. The Stent was inserted as palliation for obstruction. She was alive for 7 years after stent insertion. Stent insersion was effective for the certain period for pyloric stenosis caused by extra-compression of pseudomyx-oma peritonei.View full abstractDownload PDF (10526K) -

JOURNAL FREE ACCESSA 32-year-old female was admitted to our hospital due to general fatigue and nausea. Eleven months before this event, she had a history of ulcerative colitis, which had been treated by total colectomy. Ecdoscopic examination revealed multiple tiny ulcerations in the duode-num. X-ray examination revealed disappearance of mucosal fold, granular mucosa and lead-pipe appearance from bulb to forth portion of the duodenum. Histological findings showed crypt abscess with diffuse inflammatory changes in the duodenal mucosa. Those findings were compatible with those in ulcerative colitis. Leukocytapheresis together with steroid administra-tion improved symptoms and findings.View full abstractDownload PDF (11368K) -

JOURNAL FREE ACCESSA 80-year-old man was admitted to our hospital because of massive melena. Colonoscopic examination showed a elevated lesion with bleeding in the lower rectum, and bleeding was stopped by clipping. A inferior mesenteric angiogram revealed an arteriovenous malformation (AVM) in the peripheral lesion of the left branch of superior rectal artery. He was treated by transarterial embolization. However, 10 days after embolization, melena occurred again. Since abdominal angiography revealed a part of nidus in peripheral lesion of the right branch of superior rectal artery and the right middle rectal artery, embolization was performed again. The patient has been followed after the treatment without evidence of recurrence.View full abstractDownload PDF (9520K) -

JOURNAL FREE ACCESSThe patient was a 60-year-old male who developed the left flank pain and purpuric rashes on both lower thighs. Henoch-Schonlein purpura (HSP) was suspected, and the patient was admitted to our department on the 22nd day of illness. Double-baloon enteroscopy was performed transanally on the 29th day of illness and revealed blood-blister-like findings called hemorrhagic blebs in the mid-ileum. Circular ulcers, and irregular shaped ulcers were observed, and they appeared to be a typical small bowel lesions of HSP. The findings observed in the ileum in our patient resembled the endoscopic appearance of duodenal lesions that had been reported in the past. DBE appeared to be useful in confirming thesmall bowel lesions in HSP, the same as radiographic examinations.View full abstractDownload PDF (8320K) -

JOURNAL FREE ACCESSA 61-years-old man who had been treated acute pancreatitis visited our department with epigastric discomfort. Endoscopic examination revealed yellowish-white fluids on the angulus and the duodenal bulbus. Abdominal computed tomography scan disclosed irregular cavities around the pancreas with gas. We made a diagnosis of pancreatic abscess with fistulizations to the alimentary tract. He had a conservative therapy without abscess drainage because of the irregular cavities. This is a rare case of pancreatic abscess with fistulizations.View full abstractDownload PDF (8016K) -

JOURNAL FREE ACCESSThe narrow band imaging (NBI) system is a new illumination method for medical endoscopes in which the spectral bandwidth of the filtered light is narrowed. Until recently, iodine staining was recommended for finding superficial esophageal squamous cell carcinoma (SCC). However, unpleasant reactions such as heartburn or discom-fort sometimes occur after iodine staining. NBI, combined with magnified observation, clearly enhances the microvascular structure of the organ surface, allows us to easily detect a superficial neoplastic lesion as a clearly demarcated brownish area, without having to resort iodine staining. IPCL (intra-papillary capillary loop) pattern observed by magnifying endoscopy is expected to become as a marker for tissue structural atypism and invasion depth of cancer. On NBI observation, IPCL pattern were more clearly demonstrated with a better contrast to the background. NBI may be a promising and powerful tool to identify squamous cell carcinoma at an earlier stage in esophagus. In addition, NBI enables us to predict the diagnosis of specialized intestinal metaplasia and adenocarcinoma in Barrett's esophagus. Herein, we described the NBI findings of superficial lesions in the esophagus.View full abstractDownload PDF (13681K) -
