Inflammatory Bowel Disease V: Surgical Management01:21

Inflammatory Bowel Disease V: Surgical Management

320
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:

Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

770
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

382
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:

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

259
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 IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

325
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...

Drugs for Treatment of Diarrhea-Predominant IBS01:17

Drugs for Treatment of Diarrhea-Predominant IBS

466
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Summary
This summary is machine-generated.

A small percentage of patients with malignant colorectal polyps removed endoscopically develop lymph node (LN) metastases. Rectal polyp location may increase the risk of LN metastases, warranting further investigation.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Colorectal Surgery

Background:

  • Management of endoscopically removed malignant colorectal polyps is debated, with options including surgery or surveillance.
  • Lymph node (LN) metastases are found in 6-16% of patients with malignant polyps.
  • This study investigates LN metastasis rates in patients undergoing resection for endoscopically removed malignant polyps.

Purpose of the Study:

  • To assess the rate of lymph node (LN) metastases in patients who underwent surgical resection for malignant colorectal polyps.
  • To determine if polyp location (colon vs. rectum) influences the rate of LN metastases.

Main Methods:

  • Retrospective review of a prospectively maintained database from 2010-2018.
  • Analysis of clinical data, including patient demographics and tumor characteristics.
  • Inclusion criteria: patients undergoing surgical resection after endoscopic removal of a malignant colorectal polyp.

Main Results:

  • 177 patients underwent surgical resection; 8.5% had malignant LNs.
  • Malignant LNs were found in 5.5% of right-sided colon tumors, 5.6% of left-sided colon tumors, and 12.9% of rectal tumors.
  • No statistically significant difference in LN metastasis rates between colon and rectal polyps (P=0.090).

Conclusions:

  • A small proportion of patients with malignant polyps removed endoscopically have LN metastases.
  • Tumor location, particularly in the rectum, may be a predictive marker for LN metastases.
  • Further studies with larger patient cohorts are needed to confirm these findings.
