Underwater endoscopic mucosal resection: The third way for en bloc resection of colonic lesions?

Arterial en bloc resection for pancreatic carcinoma.

BACKGROUND Surgery for locally advanced pancreatic cancer with arterial involvement of the hepatic artery, coeliac trunk and superior mesenteric artery (SMA) is highly controversial. In a retrospective review, the benefits and harms of arterial en bloc resection (AEBR) for pancreatic adenocarcinoma with arterial involvement were analysed. METHODS Patients were divided into three groups: 29 pa...

Endoscopic mucosal resection.

EMR has become an established therapeutic option for premalignant and early-stage GI malignancies, particularly in the esophagus and colon. EMR can also aid in the diagnosis and therapy of subepithelial lesions localized to the muscularis mucosa or submucosa. Several dedicated EMR devices are available to facilitate these procedures. Adverse event rates, particularly bleeding and perforation, a...

Endoscopic mucosal resection.

An Effective Technique for Endoscopic Resection of Advanced Stage Angiofibroma

Introduction: In recent years, the surgical management of angiofibroma has been greatly influenced by the use of endoscopic techniques. However, large tumors that extend into difficult anatomic sites present major challenges for management by either endoscopy or an open-surgery approach which needs new technique for the complete en block resection.   Materials and Methods: In a prospective obse...

Line-assisted complete closure of duodenal mucosal defects after underwater endoscopic mucosal resection.

Duodenal endoscopic mucosal resection (EMR) carries a high risk of adverse events, including delayed perforation [1, 2]. Because complete clip closure of mucosal defects can reportedly prevent post-procedural adverse events in the colorectum, we established a line-assisted complete closure (LACC) technique for large mucosal defects after colonic endoscopic submucosal dissection [3]. LACC can be...
