Mistakes in gastroscopy and how to avoid them

Arne Kandulski, Jochen Weigt

Summary

AI Generated

This article addresses common pitfalls and misdiagnoses in upper GI-endoscopy performance, emphasizing that gastroscopy should not be treated as routine despite being frequently performed.

Several pitfalls in gastroscopy performance can cause serious problems or misdiagnoses, including struggles in accurately describing and classifying abnormal findings.
Key technical concerns include correct endoscope introduction technique and proper investigation of the mucosal surface using available imaging modalities such as virtual chromoendoscopy or magnification.
Critical decisions must be made immediately during endoscopy, including which classification systems to use and whether to take biopsies, as biopsies may interfere with later endoscopic resection.
The article highlights the most common clinically relevant mistakes in gastroscopy and provides guidance on how to avoid them, intended for gastroenterologists performing upper endoscopy.

Abstract

Upper GI-endoscopy is one of gastroenterology's most frequently performed diagnostic and interventional methods. Even though gastroscopy is believed to be a routine investigation - which is the greatest mistake of all - several pitfalls in performance can cause serious problems or misdiagnoses. Struggles in accurately describing and classifying abnormal findings can occur and concern the correct basic technique of endoscope introduction, and the correct way of investigating the mucosal surface in total, with several available imaging modalities such as virtual chromoendoscopy or magnification. Which classification systems should be used? The decision to perform additional workup needs to be made immediately during the ongoing endoscopy. Is it necessary to take biopsies, or should it even be avoided due to potential interference with a later endoscopic resection? This article answers the questions, highlights the most common mistakes with clinical relevance and expands on how to avoid them.
