Traditionally, choledochoceles are treated with surgical resection or endoscopic choledochal cyst fenestration with cannulation of the cyst via the native papilla and marsupialization using a sphincterotome. We describe a novel approach to management of a type IIIA choledochal cyst with endoscopic needle-knife division and marsupialization of a type IIIA choledochal cyst.</div></div><div><h3>Methods</h3><div>A 19-year-old male nonsmoker with a 5-year history of intermittent, colicky epigastric pain was referred to our tertiary center for management of a large (69 × 53 × 89 mm) type IIIA choledochal cyst confirmed on MRCP. Duodenoscopy revealed a large pendulous mass, with significant medial displacement of the duodenum and intermittent gastric outlet obstruction, that prevented clear visualization of the distally located papilla. After careful multidisciplinary team discussion, it was decided that endoscopic needle-knife division and marsupialization would be undertaken to reduce biliary stasis and the chance of further ductal stone formation.</div></div><div><h3>Results</h3><div>Needle-knife division was performed using a freehand technique using ENDO CUT I (30 W, 3d 3i). To decompress the cyst, a large incision was made from the inferior to superior position on the luminal aspect of the cyst. Further incisions were made to marsupialize the cyst cavity and allow complete drainage of the cystic content into the duodenum.

However, the snare tip can sometimes slip when opening or closing the snare, resulting in increased risk of piecemeal resection. To address this issue, we report our technique of tip-fixing underwater EMR without submucosal injection for a laterally spreading colon polyp.</div></div><div><h3>Methods</h3><div>Degassed water was infused using a mechanical water pump to completely fill the lumen.

However, submucosal injection was not required in our technique of tip-fixing underwater EMR. Essentially, intraluminal water serves as a heat sink which, when combined with a relatively thicker wall resulting from the relaxation of mucosal tension by removing intraluminal air, may protect against thermal injury of the deeper colonic wall even while making a precut with the snare tip. However, excessive snare exposure, overapplication of cautery, or deep snare driving could cause perforation, especially in thin-walled areas such as the right-sided colon or small intestine.</div></div>","PeriodicalId":55855,"journal":{"name":"VideoGIE","volume":"10 8","pages":"Pages 425-427"},"PeriodicalIF":0.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144633550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
