Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

720
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 III: Video Capsule Endoscopy

446
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,...

Assessment of the Abdomen III: Palpation

2.3K
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

239
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 Laproscopy

301
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...

Summary

Twenty-five percent of women undergoing bowel resection for endometriosis had nonvisualized, palpable satellite lesions. Some lesions as small as 2mm were found at or beyond the planned stapler site, potentially reducing repeat surgeries.

Area of Science:

  • Gynecologic surgery
  • Gastroenterology
  • Surgical oncology

Background:

  • Laparoscopic bowel resection is standard for endometriosis, but reoperation rates range from 1-16%.
  • Endometriotic lesions at stapler margins increase repeat surgery risk.
  • Small nodules (<1cm) are often missed during laparoscopy but found histologically.

Purpose of the Study:

  • To determine the prevalence of nonvisualized, palpable satellite bowel nodules near the stapler site in women undergoing bowel resection for endometriosis.

Main Methods:

  • A single-arm, observational study included 51 women undergoing laparoscopic-assisted bowel resection for deep infiltrating endometriosis.
  • Patients were assessed for nonvisualized palpable satellite lesions during routine clinical care.
  • Focus was on lesions at or near the planned stapler site.

Main Results:

  • Overall, 25.5% (13/51) of patients had nonvisualized palpable satellite lesions (as small as 2mm).
  • Seven patients (14%) had lesions at or beyond the planned stapler site.
  • Preoperative MRI did not identify these satellite lesions.

Conclusions:

  • Nonvisualized, palpable satellite lesions, even as small as 2mm, are present in a significant portion of women undergoing bowel resection for endometriosis.
  • Palpation during surgery can identify these lesions, allowing for wider resection to potentially decrease recurrent surgery rates.
  • Awareness of these lesions is crucial for surgical planning, especially in cases of repeat surgery or unexplained symptoms.
