Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

1.8K
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.

Inflammatory Bowel Disease V: Surgical Management

837
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:

  • Colorectal Surgery
  • Minimally Invasive Surgery
  • Oncology

Background:

  • Low anterior resection (LAR) poses surgical challenges for distal rectal tumors.
  • Transanal total mesorectal excision (taTME) offers a potential solution to these difficulties.

Purpose of the Study:

  • To report the initial experience and outcomes of the transanal total mesorectal excision (taTME) technique.
  • To evaluate the safety and feasibility of taTME for low rectal pathologies.

Main Methods:

  • A prospective database was maintained for 20 selected patients undergoing transanal rectal resection between June 2013 and September 2014.
  • All rectal cancer cases were reviewed in a multidisciplinary team meeting.
  • Data included operative details, postoperative complications, and oncological outcomes.

Main Results:

  • Seventeen of 20 patients had rectal cancer, with tumors located a median of 2 cm from the anorectal junction.
  • The minimally invasive approach included 16 LARs, with 94.1% intact TME specimens and an R1 rate of 5.9%.
  • Six postoperative complications occurred, including two Clavien-Dindo Grade IIIb events; median length of stay was 7 days.

Conclusions:

  • Transanal total mesorectal excision (taTME) demonstrated safety in this small patient cohort.
  • The technique is particularly beneficial for patients with narrow, irradiated pelves and distal rectal tumors.
  • Good outcomes warrant further randomized studies and international registry participation.
