Inverted colonic diverticulum (ICD): report of two cases and literature review of a not that unusual endoscopic challenge.

Inverted colonic diverticulum (ICD) is a rare intraluminal lesion occurring in about 0.7-1.7% of people, often endoscopically indistinguishable from polyps.

Combined pancreatojejunal and hepatojejunal anastomotic stent placement in total laparoscopic pancreaticoduodenectomy.

Introduction: Laparoscopic pancreaticoduodenectomy (LPD) is a technically demanding procedure that is considered safe and feasible if performed in a high-volume institution, where surgeons and medical staff is appropriately trained. For this advanced abdominal procedure only few studies described a reproducible stepwise technique and a standard approach is still lacking.

Methods: The attached video reports all steps of our standardized LPD with pancreatojejunal and hepatojejunal anastomotic stent placement performed with a double approach.

Interobserver agreement of the Paris and simplified classifications of superficial colonic lesions: a Western study.

The Paris classification of superficial colonic lesions has been widely adopted, but a simplified description that subgroups the shape into pedunculated, sessile/flat and depressed lesions has been proposed recently. The aim of this study was to evaluate the accuracy and inter-rater agreement among 13 Western endoscopists for the two classification systems. Seventy video clips of superficial colonic lesions were classified according to the two classifications, and their size estimated.
