| 1 | Efficacy and safety of emergency endoscopic retrograde cholangiopancreatography for acute cholangitis in the elderly显示文摘AIM To investigate the efficacy and safety of emergency endoscopic retrograde cholangiopancreatography(ERCP) in elderly patients with acute cholangitis. METHODS From June 2008 to May 2016, emergency ERCPs were performed in 207 cases of acute cholangitis at our institution. Patients were classified as elderly if they were aged 80 years and older(n = 102); controls were under the age of 80 years(n = 105). The patients' medical records were retrospectively reviewed for comorbidities, laboratory data, etiology of cholangitis(presence of biliary stones, biliary stricture and malignancy), details of the ERCP(therapeutic approaches, technical success rates, procedure duration), ERCP-related complications and mortality. RESULTS The frequency of comorbidities was higher in the elderly group than the control group(91.2% vs 67.6%). Periampullary diverticulum was observed in the elderly group at a higher frequency than the control group(24.5% vs 13.3%). Between the groups, there was no significant difference in the technical success rates(95.1% vs 95.2%) or endoscopicprocedure durations. With regard to the frequency of ERCP-related complications, there was no significant difference between the two groups(6.9% vs 6.7%), except for a lower rate of post-ERCP pancreatitis in the elderly group than in the control group(1.0% vs 3.8%). Neither angiographic nor surgical intervention was required in any of the cases with ERCP-related complications. There was no mortality during the observational periods. CONCLUSION Emergency ERCP for acute cholangitis can be performed safely even in elderly patients aged 80 years and older. | Gen Tohda Masahiro Ohtani Masaki Dochin | 2016 | World Journal of Gastroenterology2016，22，37： | 28 |
| 2 | Gastric adenocarcinoma of fundic gland type:Endoscopicand clinicopathological features显示文摘Gastric adenocarcinoma of fundic gland type(GA-FG) with chief cell differentiation was recently proposed as an extremely rare type of gastric adenocarcinoma. Here, we report 4 cases of GA-FG with chief cell differentiation. Endoscopic features included a submucosal tumor shape or a flat shape, whitish discoloration and dilated vessels on the surface. The tumors were located in the upper or middle third of the stomach. All cases were preoperatively diagnosed as GA-FG by biopsy, and endoscopic submucosal dissection was performed. Resected specimens revealed well-differentiated adenocarcinomas resembling chief cells. Tumor cells were diffusely positive for pepsinogen-Ⅰ, but partially positive for H+/K+-ATPase in scattered locations around the tumor margin. Despite the presence of minimal invasion of the carcinoma into the submucosal layer, which was observed in two cases, neither lymphatic nor venous invasion was detected in any of the cases. Finally, all cases showed less aggressive clinical behavior with low grade malignancy. | Gen Tohda Takeshi Osawa Yasuyuki Asada Masaki Dochin Shintarou Terahata | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，4： | 26 |
| 3 | Management of endoscopic biliary stenting for choledocholithiasis: Evaluation of stent-exchange intervals显示文摘AIM To evaluate the best management of plastic stents in patients with choledocholithiasis who were unfit for endoscopic stone removal or surgery. METHODS Between April 2007 and September 2017, 87 patients(median age 83.7 years) with symptomatic choledocholithiasis were treated with insertion of 7-Fr plastic stents because complete endoscopic stone retrieval was difficult, and their general condition was not suitable for surgery. Seventy of these patients agreed to regular stent management and stent exchange was carried out at every 6 mo(Group A, n = 35) or every 12 mo(Group B, n = 35). The remaining 17 patients did not accept regular stent exchange, and stents were replaced when clinical symptoms appeared(Group C). We evaluated the frequency of biliary complication and stent patency rate during follow-up periods. RESULTS The patency rate of biliary plastic stents was 91.4% at 6 mo(Group A) and 88.6% at 12 mo(Group B), respectively. Acute cholangitis occurred in 2.9% of Group A patients and in 8.6% of Group B patients. In Group C, median stent patency was 16.3 mo, and stent exchange was carried out in 70.6% of cases because of acute cholangitis or obstructive jaundice. Although a high incidence of acute cholangitis occurred, there was no biliary-related mortality. CONCLUSION Plastic stent exchange at 12-mo intervals is considered a safe procedure for patients with choledocholithiasis. Long-term biliary stenting increases biliary complications, but it can be an acceptable option for select patients who are medically unfit for further invasive procedures. | Gen Tohda Masaki Dochin | 2018 | World Journal of Gastrointestinal Endoscopy2018，10，1： | 5 |
