Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

2.2K
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Endoscopic Procedures V: ERCP

6.7K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.2K
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Endoscopic Procedures III: Video Capsule Endoscopy

1.4K
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Barrett Esophagus-I: Introduction01:21

Barrett Esophagus-I: Introduction

1.4K
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...

Summary

Routine upper endoscopy before bariatric surgery often reveals abnormalities but rarely changes surgical plans. Alternative screening methods for gastrointestinal conditions may be more appropriate for select patients.

Area of Science:

  • Gastroenterology
  • Bariatric Surgery
  • Endoscopy

Background:

  • Routine esophagogastroduodenoscopy (EGD) is frequently performed before bariatric surgery.
  • Its impact on patient management and surgical outcomes remains debated.
  • Preoperative EGD aims to identify conditions that might affect surgical decisions.

Purpose of the Study:

  • To determine the rate of abnormal findings on preoperative EGD in bariatric surgery candidates.
  • To assess how often these findings alter medical or surgical management.
  • To identify risk factors associated with abnormal EGD findings.

Main Methods:

  • Retrospective observational study of 232 patients undergoing bariatric surgery evaluation.
  • Review of preoperative esophagogastroduodenoscopy (EGD) findings and subsequent management changes.
  • Analysis of potential risk factors for abnormal EGD results.

Main Results:

  • Abnormal findings were detected in 61.6% of patients (143/232).
  • Medical management was altered in 15.1% (35/232), but surgical management was altered in only 1.7% (4/232).
  • Age over 55 and gastroesophageal reflux disease were linked to abnormal findings.

Conclusions:

  • Preoperative EGD in bariatric surgery candidates frequently reveals abnormalities.
  • However, these findings rarely lead to changes in surgical management.
  • Consideration of alternative screening strategies for common GI conditions is warranted.
