Advantages of Laparoscopic Abdominoperineal Resection for Anastomotic Recurrence of Rectal Cancer

Background: Surgery offers the only potential for cure and long-term survival of recurrence of rectal cancer.Few studies about laparoscopic recurrent lesion resection have been reported. This study was designed to evaluatethe safety and feasibility of laparoscopic abdomino-perineal resection for anastomotic recurrence of rectal cancer.Materials and
Methods: Data for 42 patients with recurrence of rectal cancer were collected retrospectively. Of the42 patients, 22 underwent laparoscopic surgery (LR group) and 20 received open surgery (OR group). Outcomesbetween the two groups were compared.
Results: Operation time in LR group was shorter compared with theOR group (164.6±27.7min vs 203.0±45.3min); intra-operative blood loss was 119.7±44.4ml and 185.0±94.0ml inLR group and OR group, respectively (p<0.001); time to first flatus in LR group was shorter than in OR group,and the difference was statistically significant (2.6±0.8 days vs 3.1±0.8 days, p=0.013); hospital stay in the LRand OR groups was 8.6±1.3 days and 9.8±2.2 days; 3-year survival rates in the LR and OR groups were 44.4%and 42.8% (p=0.915) and the 3-year disease-free survival rates were 36.4% and 30.0%, respectively (p=0.737).
Conclusions: Laparoscopic abdomino-perineal resection is safe and feasible for anastomotic recurrence of rectalcancer.
