Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

149
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

115
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 II: Colonoscopy

54
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

47
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

Total pelvic exenteration (TPE) for T4b colorectal cancer (CRC) has high short- and intermediate-term complication risks. Many complications occur after 30 days, necessitating extended recovery awareness for patients undergoing TPE.

Area of Science:

  • Surgical Oncology
  • Gastroenterology
  • Clinical Medicine

Background:

  • Total pelvic exenteration (TPE) for advanced colorectal cancer (CRC) is linked to substantial morbidity.
  • Understanding short-term (0-30 days) and intermediate-term (31-90 days) complication timing is crucial for patient counseling before TPE.

Purpose of the Study:

  • To analyze the temporal onset of postoperative complications within 90 days following TPE for clinical T4b CRC.
  • To identify predictors of postoperative morbidity in patients undergoing TPE for T4b CRC.

Main Methods:

  • Retrospective cohort study of 27 patients with primary or recurrent clinical T4b pelvic CRC undergoing open TPE (2014-2023).
  • Complications classified by Clavien-Dindo (CD) grade and stratified by time of onset (within 90 days).
  • Statistical analysis included Chi-square, Fisher's Exact, Mann-Whitney U tests, and logistic regression (R software, p<0.05).

Main Results:

  • 85.2% of patients experienced complications within 90 days; no mortality was observed.
  • 37.0% had Clavien-Dindo grade ≥ 3 events, with 40% occurring after 30 days.
  • Anemia requiring transfusion was the most common complication; pelvic abscess was the most common major complication. No clinicopathologic variables predicted major complications.

Conclusions:

  • TPE for clinical T4b CRC presents a high risk of short- and intermediate-term postoperative morbidity.
  • A significant portion of complications arise after 30 days, indicating a need for extended recovery expectations.
  • This complication profile can aid informed consent discussions for TPE.
