Tip 50: Demonstration of Passage of a Narrowed and Angulated Sigmoid | February 2022-Demonstration of Passage of a Narrowed and Angulated Sigmoid

Demonstration of Passage of a Narrowed and Angulated Sigmoid

Video Transcription

Video Summary

In this video, a case of cecal intubation in a patient with a narrowed and angulated sigmoid colon is shown. The patient had a poor prep proximal to the sigmoid, requiring a different approach. The key learning tips discussed are the importance of scope diameter and length of the bending section, using water insertion for safety and success in a narrow and angulated colon, and the use of the left-hand scope grip for better control. The video demonstrates the use of an ultra-thin scope, water pumping instead of gas, and the difficulty in finding the lumen due to severe angulation. Despite limitations in prep, the video shows successful intubation of the cecum. Credits: ASGE SuTab tip of the week.
