Long-term adenoma recurrence and development of colorectal cancer following endoscopic mucosal resection in large non-pedunculated colonic polyps ≥4 cm.

Objectives: Data of long-term follow up for large non pedunculated colorectal polyps (LNPCPs) ≥4 cm removed with piecemeal wide field endoscopic mucosal resection (PWF-EMR) are limited. We primarily evaluated the recurrence rates and secondarily the rates of post colonoscopic polypectomy colorectal cancer (PCPCRC) on a long-term basis.

Methods: We retrospectively reviewed a prospectively-stored electronic database of all patients who underwent PWF-EMR for LNPCPs at the Venizeleion General Hospital, between 2009 and 2020.

A rare case of massive hepatic abscess 6 years after ERCP due to retained biliary stent.

Backround: ERCP combined with the insertion of biliary endoprosthesis is considered a daily practice endoscopic intervention for the treatment of choledocholithiasis. Nevertheless, retained biliary stents for a prolonged period without follow up may cause serious complications.

Case Presentation: We present the case of a 62-year-old man who was hospitalized with symptoms of vomiting, abdominal pain, fatigue and fever.
