Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

532
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
This summary is machine-generated.

Laparoscopic abdominoperineal resection (LAPR) shows fewer early postoperative complications, reduced blood loss, and shorter hospital stays compared to open APR (OAPR). This minimally invasive approach may be a viable option for low rectal cancer patients.

Area of Science:

  • Colorectal Surgery
  • Minimally Invasive Surgery
  • Surgical Oncology

Background:

  • Abdominoperineal resection (APR) is standard for low rectal cancer (RC).
  • Laparoscopic APR (LAPR) offers potential benefits over open APR (OAPR).
  • Comparative data on early postoperative complications between LAPR and OAPR is limited at Jinnah Postgraduate Medical Centre (JPMC), Karachi.

Purpose of the Study:

  • To compare 30-day postoperative complications between LAPR and OAPR for low RC.
  • To evaluate secondary outcomes including surgical site infection (SSI), pulmonary complications, blood loss, operative time, and hospital stay.

Main Methods:

  • Prospective, comparative observational study at JPMC, Karachi (January 2024 - January 2025).
  • 90 patients with low rectal adenocarcinoma randomized into LAPR (Group A) and OAPR (Group B).
  • Monitoring for 30-day postoperative complications including SSIs, pulmonary issues, ileus, and reoperations; statistical analysis using IBM SPSS.

Main Results:

  • LAPR group had longer operative time (195.2 min vs. 158.7 min) but significantly reduced intraoperative blood loss (120.5 mL vs. 285.3 mL).
  • LAPR patients experienced shorter hospital stays (6.2 days vs. 9.3 days) and fewer overall complications (20% vs. 51.1%).
  • Significantly lower rates of surgical site infections (8.9% vs. 24.4%) and pulmonary complications (2.2% vs. 13.3%) in the LAPR group.

Conclusions:

  • Laparoscopic APR is associated with fewer early postoperative complications, reduced blood loss, and shorter hospital stays compared to open APR.
  • LAPR demonstrates potential as a favorable surgical option for selected low rectal cancer patients.
  • Further multicenter randomized trials are needed to confirm these findings and assess long-term oncologic outcomes.
