First Year Fellows Endoscopy Course (July 31 - August 1)

5-Tools of the Trade

Pdf Summary

This document provides an overview of the tools used in endoscopy procedures. The scope anatomy includes the umbilicus, connectors, insertion tube, and handle. The insertion tube contains the bending section, air-water-suction system, and various channels for instruments. CO2 can be used instead of room air for insufflation, resulting in improved patient satisfaction and fewer complications.<br /><br />Different types of endoscopes have varying dimensions, including insertion tube diameter and channel diameter. It is crucial to know the length and size of the scope being used.<br /><br />Before starting an endoscopy, several checks should be completed, such as ensuring the air and water, suction, and irrigation systems are working properly, and the image on the screen is clear.<br /><br />The most commonly used devices in endoscopy are biopsy forceps, polypectomy snares, retrieval nets, injection needles, and clips.<br /><br />Biopsy forceps have different sizes and jaw openings and can be used to determine lesion size. Taking multiple biopsies increases the likelihood of obtaining an accurate diagnosis.<br /><br />Polypectomy snares come in various sizes and shapes, and the choice depends on factors such as lesion location, size, and morphology. Different techniques, such as hot or cold snare polypectomy, can be used.<br /><br />Retrieval nets are used to remove objects like polyps, food, or foreign bodies. The differences between nets include material, size, and rotatability.<br /><br />Injection needles are used for submucosal injections and have various characteristics such as gauge, length, and adjustable features.<br /><br />Endoclips are mechanical compression devices used for various purposes, such as stopping non-variceal bleeding or closing defects. Different types of clips have varying features like jaw opening, ability to reopen, or rotate.<br /><br />Overall, understanding the different tools and their uses is crucial for successful endoscopy procedures.
