Pdf Summary

This document provides an overview of the different tools used in endoscopy procedures. It begins by discussing the anatomy of endoscopes, including the insertion tube, bending section, and various channels for air, water, and instruments. It mentions the use of CO2 instead of room air for improved patient satisfaction and fewer complications.<br /><br />Next, the document highlights the importance of knowing the length, insertion tube diameter, and channel diameter of each scope used. It provides a checklist before starting endoscopy, which includes checking the functionality of air, water, suction, and image on the screen.<br /><br />The most frequently used devices in endoscopy are mentioned, such as biopsy forceps, polypectomy snares, retrieval nets, injection needles, and clips. The document explains the importance of verifying compatibility between the accessory and endoscope and knowing the length and diameter of both.<br /><br />For biopsy forceps, it explains the different sizes available and the importance of using larger forceps for better sample collection. It mentions the value of a central spike in anchoring forceps onto the mucosa and allowing for deeper sampling.<br /><br />The document discusses snares and their different sizes and configurations based on the location, size, and morphology of the lesion. It explains the techniques for snare polypectomy, including hot and cold methods, and the use of saline lift.<br /><br />Retrieval nets are explained as soft, flexible mesh attached to a snare, used for containing and removing objects like polyps, food, and foreign bodies.<br /><br />Injection needles are used for submucosal injections and have different characteristics such as gauge, length, adjustability, and the ability to be locked. Their various indications are mentioned, including hemostasis, polypectomy, and injection of pharmacologically active agents.<br /><br />Endoclips are mechanical compression devices used for various purposes such as closing defects, managing bleeding, and anchoring feeding tubes. Different types of clips are mentioned, along with their characteristics and deployment techniques.<br /><br />Overall, this document provides a comprehensive overview of the tools used in endoscopy procedures, highlighting their different features, functions, and techniques for optimal use.
