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 II: Colonoscopy

1.2K
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:

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Area of Science:

  • Surgical Education
  • Minimally Invasive Surgery
  • Colorectal Surgery

Background:

  • Existing laparoscopic colorectal surgery training lacks segmentation for focused skill development.
  • A standardized, segment-based training approach is needed for consistency across institutions.
  • This study aimed to define key procedural steps for targeted laparoscopic colectomy training.

Purpose of the Study:

  • To achieve expert consensus on the critical steps of laparoscopic right hemicolectomy.
  • To achieve expert consensus on the critical steps of laparoscopic sigmoid colectomy.
  • To establish a foundation for the INVEST video-assisted training curriculum.

Main Methods:

  • The Delphi method was employed to gather expert opinions.
  • A comprehensive list of procedural steps was compiled from established guidelines.
  • 22 experts rated the importance of each step via online questionnaires over two rounds.

Main Results:

  • Consensus was achieved among 14 participating experts across two rounds.
  • High internal consistency was demonstrated (Cronbach's alpha 0.79 for right hemicolectomy, 0.91 for sigmoid colectomy).
  • 25 key steps for laparoscopic right hemicolectomy and 24 for sigmoid colectomy were identified.

Conclusions:

  • Expert consensus was successfully reached on the essential steps for both laparoscopic procedures.
  • The identified key steps will be integrated into a video-assisted training module.
  • This curriculum aims to standardize and enhance surgical resident education in laparoscopic colectomy.
