Summary
Laparoscopic abdominoperineal resection (APR) for lower rectal cancer shows technical efficiency and quick recovery. Short-term oncologic results are acceptable, but long-term follow-up is needed for definitive outcomes.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
- Colorectal Surgery
Background:
- Laparoscopic approach for rectal cancer resection remains controversial, unlike its established use in colon cancer.
- This study investigates the feasibility of laparoscopic abdominoperineal resection (APR) for lower rectal cancers.
Purpose of the Study:
- To evaluate the technical efficiency and outcomes of laparoscopic abdominoperineal resection (APR) for lower rectal cancers.
- To assess the safety and recovery profile of this minimally invasive surgical approach.
Main Methods:
- A prospective phase II study involving 22 patients with lower rectal adenocarcinoma (within 6 cm of the anal verge).
- Surgical principle: en bloc resection with high ligation of inferior mesenteric vessels (no-touch isolation) and total mesorectal excision.
- Laparoscopic APR procedure details were documented, and outcomes were prospectively evaluated.
Main Results:
- The study included 22 patients (12 female, 10 male; mean age 62.5 years).
- Mean operation time was 214 minutes with minimal blood loss (54 ml). No major complications occurred; one patient had wound infection.
- Patients experienced quick convalescence: postoperative ileus (48h), hospitalization (8 days), and pain (3.5 VAS). Return to work averaged 6 weeks.
- Short-term follow-up (18 months median) showed one lung metastasis and two local recurrences.
Conclusions:
- Laparoscopic APR is technically feasible in a clinical setting, offering good efficiency and rapid functional recovery.
- Short-term oncologic outcomes appear acceptable, but long-term data are essential to confirm efficacy.
- Further long-term follow-up is mandatory to fully define the oncologic outcomes of laparoscopic APR for lower rectal cancer.
