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 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:
Inflammatory Bowel Disease V: Surgical Management01:21

Inflammatory Bowel Disease V: Surgical Management

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:
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.

Area of Science:

  • Gastroenterology
  • Endoscopic Procedures
  • Colorectal Cancer Prevention

Background:

  • Colonoscopic polypectomy is crucial for reducing colorectal cancer incidence and mortality.
  • Cold snare technique is preferred for small and diminutive polyps due to elimination of electrosurgical risks.

Purpose of the Study:

  • To review the effectiveness and safety of colonoscopic polypectomy techniques.
  • To highlight the need for further research into operator variation and best practices.

Main Methods:

  • Review of existing clinical trial data on polypectomy techniques.
  • Analysis of the impact of polypectomy on the polyp-cancer sequence.

Main Results:

  • Cold snare technique is favored for small/diminutive polyps, avoiding electrosurgical risks.
  • Limited clinical trial data exist for specific polypectomy techniques.
  • Significant variability in polypectomy techniques among endoscopists is observed.

Conclusions:

  • Standardization of colonoscopic polypectomy techniques is necessary.
  • Further research is required to establish evidence-based best practices and address operator variability.
  • Optimizing polypectomy techniques can further reduce colorectal cancer burden.
