Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

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 I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

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: ERCP01:26

Endoscopic Procedures V: ERCP

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 II: Colonoscopy01:25

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:
Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

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, unexplained...

Summary

Laparoscopic-assisted transgastric endoscopy provides a safe and effective method for accessing the upper gastrointestinal tract when traditional endoscopic methods are challenging due to altered anatomy. This technique facilitates therapeutic procedures with minimal complications.

Area of Science:

  • Minimally Invasive Surgery
  • Gastroenterology
  • Surgical Innovation

Background:

  • Proximal gastrointestinal tract access can be challenging due to anatomical variations.
  • Laparoscopic visualization allows trocar placement into the stomach for endoscope introduction.
  • This study evaluates a novel laparoscopic-assisted transgastric endoscopy technique.

Purpose of the Study:

  • To describe the technique of laparoscopic-assisted transgastric endoscopy.
  • To demonstrate the safety, effectiveness, and feasibility of this approach.
  • To address limitations in traditional endoluminal therapy access.

Main Methods:

  • Six patients with altered proximal foregut anatomy were studied.
  • Procedures included laparoscopic port placement and anterior gastrotomy for endoscope insertion.
  • Simultaneous laparoscopic and endoscopic monitoring was utilized.

Main Results:

  • All therapeutic endoscopic retrograde cholangiopancreatography (ERCP) procedures were successful.
  • Operative times ranged from 64 to 93 minutes.
  • Patients experienced minimal postoperative pain with no complications.

Conclusions:

  • Laparoscopic-assisted transgastric endoscopy serves as a viable portal for gastrointestinal access.
  • This technique is safe and efficient for patients with limited traditional endoscopic access.
  • It offers a solution for complex cases requiring endoscopic intervention.
