Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

551
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 V: ERCP

2.7K
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 I: Esophagogastroduodenoscopy

884
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 III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

709
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: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

612
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:

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

814
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
Nasointestinal Feeding
Nasointestinal feeding involves placing a tube...

Area of Science:

  • Gastroenterology
  • Bariatric Surgery
  • Endoscopy

Background:

  • Obesity is a major global health concern requiring effective interventions.
  • Bariatric surgery is the primary treatment for severe obesity.
  • The necessity of routine preoperative Esophagogastroduodenoscopy (EGD) before bariatric surgery is debated.

Purpose of the Study:

  • To assess the diagnostic yield and impact of preoperative Esophagogastroduodenoscopy (EGD) in a Turkish cohort undergoing bariatric surgery.
  • To determine the prevalence of upper gastrointestinal pathologies detected by EGD in patients seeking bariatric procedures.

Main Methods:

  • Retrospective cross-sectional analysis of 117 patients undergoing Laparoscopic Sleeve Gastrectomy (LSG) or Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) from 2018-2021.
  • Data collected included demographics, comorbidities, endoscopic findings, histopathology, and surgical modifications.
  • Analysis of pathologies identified via EGD and their influence on surgical management.

Main Results:

  • Preoperative EGD revealed significant pathology in 86.3% of patients.
  • Common findings included antral gastritis (64.1%), hiatal hernia (22.2%), and erosive esophagitis (18.8%).
  • Histopathology confirmed chronic gastritis in 74.4%, with 15.4% having active Helicobacter pylori infection. EGD findings altered surgical plans in 18.8% of cases.

Conclusions:

  • Routine preoperative Esophagogastroduodenoscopy (EGD) is beneficial in bariatric surgery for detecting significant upper gastrointestinal conditions.
  • EGD findings can directly impact surgical decision-making and management strategies.
  • Further prospective, multicenter research is recommended to solidify these findings.
