Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

503
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...

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:

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:

Summary
This summary is machine-generated.

Colorectal cancer surgery in patients 75 and older has acceptable outcomes. A high Charlson Comorbidity Index (CCI) score predicts complications, while minimally invasive surgery may improve results.

Area of Science:

  • Geriatric Surgery
  • Surgical Oncology
  • Outcomes Research

Background:

  • Elderly patients (≥75 years) with colorectal cancer (CRC) are underrepresented in outcomes research.
  • Accurate risk stratification is crucial for surgical decision-making in this demographic.
  • The Charlson Comorbidity Index (CCI) is a key tool for assessing comorbidity burden.

Purpose of the Study:

  • To evaluate the outcomes of colorectal cancer resection in patients aged 75 years and older.
  • To assess the predictive value of the Charlson Comorbidity Index (CCI) for adverse outcomes in this population.
  • To determine the impact of surgical approach on outcomes.

Main Methods:

  • Retrospective review of 211 patients (≥75 years) undergoing CRC resection (Jan 2019 - Sep 2024).
  • Primary outcome: composite of major postoperative complications (Clavien-Dindo grade ≥3) or 30-day mortality.
  • Stratification by CCI (≥5 vs. <5); analysis included chi-square, Fisher's exact, and Mann-Whitney U tests.

Main Results:

  • Median age was 81 years; 24.6% had a CCI ≥ 5.
  • Patients with CCI ≥ 5 had significantly higher rates of major complications or 30-day mortality (29.4% vs. 11.9%, p=0.04).
  • Laparoscopic resection was independently protective (aOR 0.37, p=0.048); age ≥85 and emergency presentation were not significant predictors.

Conclusions:

  • Colorectal resection in patients ≥75 years is associated with acceptable morbidity and low mortality.
  • A CCI ≥ 5 is a significant predictor of adverse outcomes in elderly CRC patients.
  • Minimally invasive surgery may offer advantages for this high-risk group.
