[The 5-5-2 criteria for biliary cannulation and post endoscopic retrograde cholangiopancreatography complications: Experience in a reference hospital, Peru].

The European Society for Gastrointestinal Endoscopy (ESGE) defines "difficult biliary cannulation" by the presence of one or more of the following: more than 5 contacts with the papilla, more than 5 minutes attempting to cannulate, or inadvertent cannulation of the pancreatic duct in 2 or more times (5-5-2 criteria), recommending these cut-off points to perform advanced cannulation techniques in order to reduce the rate of post-ERCP adverse events. Our objective was to evaluate the performance of the 5-5-2 criteria and their association with post-ERCP complications in a reference hospital in Peru. We performed a prospective analytical case-control study and 120 patients who underwent ERCP were enrolled.

[Medical and surgical management of moderate-to-severe inflamatory bowel disease].

Unlabelled: The management of inflammatory bowel disease (IBD) is mainly medical, however, more than 70% of patients with Crohn's disease (CD) and 25% with ulcerative colitis (UC) will require surgery during their lifetime.

Objective: To evaluate medical, surgical management and evolution in patients with moderate-to-severe IBD.

Materials And Methods: Observational, descriptive, retrospective study from January 2011 to December 2019 in the Gastroenterology Service of the Guillermo Almenara Irigoyen National Hospital, Lima-Peru.

[Clinical-pathological characteristics and endoscopic management of colonic sessile serrated lesions in a reference hospital in Lima - Peru].

Unlabelled: Colorectal cancer (CRC) is one of the most frequent worldwide. Approximately one third of cases originate from the serrated pathway of carcinogenesis, with colonic sessile serrated lesions (SSL) being the main cause of interval CRC.

Objective: To evaluate the clinical, endoscopic, histological characteristics and endoscopic management of colonic LSS.
