Endoclips to Facilitate Cannulation and Sphincterotomy During ERCP in a Patient with an Ampulla Within a Large Duodenal Diverticulum: Case Report and Literature Review

Cannulation and sphincterotomy of the ampulla may be technically challenging at endoscopic retrograde cholangiopancreatography (ERCP) when the ampulla is located within a duodenal diverticulum because of obscuring of the ampulla and approaching it from an awkward angle. Successful application of endoclips to expose and facilitate cannulation of an ampulla within a duodenal diverticulum has been reported for three cases of diagnostic ERCP [1, 2] and one case of therapeutic ERCP . A second case is hereby reported of clinically beneficial, successful, therapeutic ERCP using endoclips.
Cases of facilitated cannulation at ERCP in association with duodenal diverticulum were identified by computerized literature search using terms “diverticulum” and (“ERCP” or “sphincterotomy” or “papillotomy” or “stone extraction,” or “common bile duct stones” or “CBD stones” or “choledocholithiasis”). Cases of facilitated cannulation at ERCP using endoclips were identified by adding “hemoclips”...
