Our experience at Bangabandhu Sheikh Mujib Medical University on laparoscopic assisted surgery for rectal cancer

Abstract

Background: Rectal cancer is a leading cause of mortality worldwide, with laparoscopic surgery emerging as a viable alternative to open surgery due to its benefits in postoperative recovery, pain management and survival rates. Despite its advantages, laparoscopic colorectal resection faces scrutiny over oncologic safety and technical demands, limiting its widespread adoption. Methods: This retrospective descriptive study analyzed 60 patients with colorectal adenocarcinoma treated at the Department of Colorectal Surgery, BSMMU, from January 2018 to December 2018. Inclusion criteria encompassed clinically diagnosed colorectal cancer with histological confirmation. Data on demographics, tumor characteristics, surgical details and postoperative outcomes were collected and analyzed with SPSS software. Results: Among the 60 patients, 32 were male, with a mean age of 52 years. Tumors within 5 cm of the anal verge necessitated abdominoperineal resections (n=44), while anterior resections were performed for the remaining (n=16). All patients achieved adequate proximal margins (>5 cm) and most (90%) had distal margins >2 cm. The average operative time ranged from 190 to 270 minutes, with no intraoperative complications and a postoperative stay of 3-5 days. Patients reported less postoperative pain and faster recovery. Conclusions: Laparoscopic colorectal surgery demonstrated similar oncologic outcomes to open surgery but involved a longer operative time and required advanced surgical skills. The benefits included reduced blood loss, lower postoperative pain and a shorter hospital stay, although costs were higher. A need for expert surgeons in selected patients is emphasized for optimal outcomes. Laparoscopic resection for rectal cancer aligns with oncologic principles and offers a safe, effective approach, yielding improved recovery metrics compared to traditional surgery. Further analysis on cost-effectiveness, especially for lower socioeconomic populations, is warranted to enhance accessibility.
