The study demonstrates that laparoscopic rectal cancer surgery is associated with comparable short-term outcomes in terms of operative time and postoperative morbidity to open surgery, with the added benefit of a faster recovery. Additionally, there were no significant differences observed between laparoscopic and open surgery in terms of oncological adequateness of the surgical specimen and long-term survival rates.
Background Laparoscopic resections for rectal cancer are routinely performed in high-volume centres. Despite short-term advantages have been demonstrated, the oncological outcomes are still debated. The aim of this study was to compare the oncological adequateness of the surgical specimen and the long-term outcomes between open (ORR) and laparoscopic (LRR) rectal resections. Methods Patients undergoing laparoscopic or open rectal resections from January 1, 2013, to December 31, 2019, were enrolled. A 1:2 propensity score matching was performed according to age, sex, BMI, ASA score, comorbidities, distance from the anal verge, and clinical T and N stage. Results Ninety-eight ORR were matched to 50 LRR. No differences were observed in terms of operative time (224.9 min. vs. 230.7; p = 0.567) and postoperative morbidity (18.6% vs. 20.8%; p = 0.744). LRR group had a significantly earlier soft oral intake (p < 0.001), first bowel movement (p < 0.001), and shorter hospital stay (p < 0.001). Oncological adequateness was achieved in 85 (86.7%) open and 44 (88.0%) laparoscopic resections (p = 0.772). Clearance of the distal (99.0% vs. 100%; p = 0.474) and radial margins (91.8 vs. 90.0%, p = 0.709), and mesorectal integrity (94.9% vs. 98.0%, p = 0.365) were comparable between groups. No differences in local recurrence (6.1% vs.4.0%, p = 0.589), 3-year overall survival (82.9% vs. 91.4%, p = 0.276), and disease-free survival (73.1% vs. 74.3%, p = 0.817) were observed. Conclusions LRR is associated with good postoperative results, safe oncological adequateness of the surgical specimen, and comparable survivals to open surgery.
