Summary

Laparoscopic abdominoperineal resection for low rectal cancer offers faster recovery and shorter hospital stays compared to open surgery. This minimally invasive approach is safe, feasible, and yields similar oncologic outcomes.

Area of Science:

  • Colorectal Surgery
  • Surgical Oncology
  • Minimally Invasive Surgery

Background:

  • Low rectal cancer necessitates surgical intervention, often abdominoperineal resection.
  • Conventional open surgery carries risks of prolonged recovery and complications.
  • Laparoscopic techniques offer potential benefits in surgical recovery and patient outcomes.

Purpose of the Study:

  • To prospectively compare laparoscopic abdominoperineal resection (APR) with conventional APR for low rectal cancer.
  • To evaluate operative parameters, postoperative recovery, and oncologic outcomes between the two surgical approaches.

Main Methods:

  • Prospective comparison of 18 patients undergoing laparoscopic APR (Group 1) and 18 patients undergoing conventional APR (Group 2).
  • Key parameters assessed: operative time, ileus, diet reintroduction, hospitalization duration, conversion rate, morbidity, mortality, and local recurrence.

  • Histopathological analysis of resection specimens (margins, lymph nodes) was performed for both groups.

    • Main Results:

    • Laparoscopic APR showed statistically significant reductions in time to diet reintroduction (2.5 vs. 3.8 days) and hospital stay (7.4 vs. 12.9 days).
    • Operative time was slightly longer in the laparoscopic group (229 vs. 208 min), but not statistically significant.
    • Histopathology, major complications, conversion rate (10%), mortality (one in conventional group), and local recurrence rates were similar between groups.

    Conclusions:

    • Oncologic laparoscopic abdominoperineal resection is technically feasible and safe for low rectal cancer.
    • The laparoscopic approach provides superior postoperative recovery and equivalent early oncologic outcomes compared to open surgery.
    • Laparoscopic APR represents a viable alternative to conventional surgery, enhancing patient recovery without compromising oncologic control.
