| 1 | Clinical usefulness of endoscopic ultrasonography for the evaluation of ulcerative colitis-associated tumors显示文摘AIM:To evaluate the clinical usefulness of endoscopic ultrasonography(EUS) for the diagnosis of the invasion depth of ulcerative colitis-associated tumors.METHODS:The study group comprised 13 patients with 16 ulcerative colitis(UC)-associated tumors for which the depth of invasion was preoperatively estimated by EUS.The lesions were then resected endoscopically or by surgical colectomy and were examined histopathologically.The mean age of the subjects was 48.2 ± 17.1 years,and the mean duration of UC was 15.8 ± 8.3 years.Two lesions were treated by endoscopic resection and the other 14 lesions by surgical colectomy.The depth of invasion of UCassociated tumors was estimated by EUS using an ultrasonic probe and was evaluated on the basis of the deepest layer with narrowing or rupture of the colonic wall.RESULTS:The diagnosis of UC-associated tumors by EUS was carcinoma for 13 lesions and dysplasia for 3 lesions.The invasion depth of the carcinomas was intramucosal for 8 lesions,submucosal for 2,the muscularis propria for 2,and subserosal for 1.Eleven(69%) of the 16 lesions arose in the rectum.The macroscopic appearance was the laterally spreading tumor-non-granular type for 4 lesions,sessile type for 4,laterally spreading tumor-granular type for 3,semipedunculated type(Isp) for 2,type 1 for 2,and type 3 for 1.The depth of invasion was correctly estimated by EUS for 15 lesions(94%) but was misdiagnosed as intramucosal for 1 carcinoma with high-grade submucosal invasion.The 2 lesions treated by endoscopic resection were intramucosal carcinoma and dysplasia,and both were diagnosed as intramucosal lesions by EUS.CONCLUSION:EUS provides a good estimation of the invasion depth of UC-associated tumors and may thus facilitate the selection of treatment. | Kiyonori Kobayashi Kana Kawagishi Shouhei Ooka Kaoru Yokoyama Miwa Sada Wasaburo Koizumi | 2015 | World Journal of Gastroenterology2015，21，9： | 5 |
| 2 | Immediate detection of endoscopic retrograde cholangiopancreatographyrelated periampullary perforation: Fluoroscopy or endoscopy?显示文摘AIM:To investigate the causes and intraoperative detection of endoscopic retrograde cholangiopancreatography(ERCP)-related perforations to support immediate or early diagnosis.METHODS:Consecutive patients who underwent ERCP procedures at our hospital between January2008 and June 2013 were retrospectively enrolled in the study(n=2674).All procedures had been carried out using digital fluoroscopic assistance with the patient under conscious sedation.For patients showing alterations in the gastrointestinal anatomy,a short-type double balloon enteroscope had been applied.Cases of perforation had been identified by the presence of air in or leakage of contrast medium into the retroperitonealspace,or upon endoscopic detection of an abdominal cavity related to the perforated lumen.For patients with ERCP-related perforations,the data on medical history,endoscopic findings,radiologic findings,diagnostic methods,management,and clinical outcomes were used for descriptive analysis.RESULTS:Of the 2674 ERCP procedures performed during the 71-mo study period,only six(0.22%)resulted in perforations(male/female,2/4;median age:84 years;age range:57-97 years).The cases included an endoscope-related duodenal perforation,two periampullary perforations related to endoscopic sphincterotomy,two periampullary perforations related to endoscopic papillary balloon dilation,and a periampullary or bile duct perforation secondary to endoscopic instrument trauma.No cases of guidewire-related perforation occurred.The video endoscope system employed in all procedures was only able to immediately detect the endoscope-related perforation;the other five perforation cases were all detected by subsequent digital fluoroscope applied intraoperatively(at a median post-ERCP intervention time of 15 min).Three out of the six total perforation cases,including the single case of endoscope-related duodenal injury,were surgically treated;the remaining three cases were treated with conservative management,including trans-arterial embolization to control the bleeding in one of the cases.All patients recovered without further incident.CONCLUSION:ERCP-related perforations may be difficult to diagnose by video endoscope and digital fluoroscope detection of retroperitoneal free air or contrast medium leakage can facilitate diagnosis. | Yasuaki Motomura Kazuya Akahoshi Junya Gibo Kenji Kanayama Shinichiro Fukuda Shouhei Hamada Yoshihiro Otsuka Masaru Kubokawa Kiyoshi Kajiyama Kazuhiko Nakamura | 2014 | World Journal of Gastroenterology2014，20，42： | 5 |
