Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

178
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 IV: Sigmoidoscopy and Laproscopy

157
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...

Inflammatory Bowel Disease V: Surgical Management

197
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:

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

138
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

823
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
  • Endoscopy
  • Surgical Oncology

Background:

  • Resection of adenomatous colorectal polyps reduces colorectal cancer mortality.
  • Simpler, safer colorectal polypectomy methods are needed for complete lesion resection.
  • Cold snare polypectomy (CSP) offers advantages over hot snare polypectomy for smaller polyps.

Purpose of the Study:

  • To review the efficacy and safety of CSP for non-pedunculated polyps <10 mm.
  • To describe technical aspects of CSP based on current evidence.
  • To explore expanding CSP indications and discuss recurrent lesion management.

Main Methods:

  • Review of previous studies on CSP efficacy and safety.
  • Analysis of technical points for CSP practice.
  • Discussion of evidence for expanded CSP indications.

Main Results:

  • CSP shows similar complete resection rates to hot snare polypectomy for polyps <10 mm.
  • CSP offers shorter procedure times, reduced bleeding risk, and lower costs.
  • Evidence supports expanding CSP for larger, pedunculated, or near-appendiceal orifice lesions.

Conclusions:

  • CSP is a safe and effective endoscopic resection method for small colorectal polyps.
  • Technical refinements and expanded indications enhance CSP's utility.
  • Further research is needed for managing recurrent lesions after CSP.
