Purpose
Two non-inferiority randomised control trials have questioned the utility of laparoscopic surgery for rectal cancer by failing to prove that pathological markers of high-quality surgery are equivalent to those achieved by open technique. We present short- and long-term post-operative outcomes from the largest single surgeon series of consecutive patients undergoing laparoscopic TME for rectal cancer. We describe the standardised laparoscopic technique developed by the principal surgeon, and the short-term outcomes from three surgeons who were trained in and subsequently adopted the same approach.
Methods
Prospectively acquired data from consecutive patients undergoing surgery for rectal cancer by the principal surgeon at the minimally invasive colorectal unit in Portsmouth between 2006 and 2014 were analysed along with data acquired between 2010 and 2017 from surgeons at three further international centres. Endpoints were overall and disease-free survival at 5 years, and early post-operative clinical and pathological outcomes.
Results
Two hundred sixty-three consecutive patients underwent laparoscopic TME surgery by the principal surgeon. At 5 years, overall survival was 82.9% (Dukes’ A = 94.4%; B = 81.6%; C = 73.7%); disease-free survival was 84.0% (Dukes’ A = 93.3%; B = 86.8%; C = 72.6%). Post-operative length of stay, lymph node harvest, mean operating time, rate of conversion, major morbidity and 30-day mortality were not significantly different between the principal surgeon and those he had trained when subsequently in independent practices.
Conclusion
Laparoscopic TME produces excellent long-term survival outcomes for patients with rectal cancer. A standardised approach has the potential to improve outcomes by setting benchmarks for surgical quality, and providing a step-by-step method for surgical training.
