Comparative observation of short-term clinical outcome of laparoscopic and open transabdominal perineal resection for low rectal cancer

Abstract

Objective To compare the short-term clinical outcome of laparoscopic and open transabdominal perineal resection for low rectal cancer. Methods 110 patients with low rectal cancer from December 2014 to December 2018 were divided into two groups by using random number table method, including 55 cases in the open group and 55 cases in the combined group. Statistical analysis were performed by using SPSS24.0 software. Measurement data such as surgical indicators and intestinal function were represented as (±s) and were examined by using t test. Postoperative complications and 3-months recurrence rate were analyzed by using χ2 test. A P value of <0.05 was considered as statistical significant difference. Results The amount of intraoperative bleeding and the length of resected specimens in the combined group were lower than those in the open group respectively (P 0.05). The removal time of perineal drainage tubes, exhaust time, and postoperative hospital stay in the combined group were less than those in the open group respectively (P 0.05). Conclusion Laparoscopic transabdominal perineal resection and traditional open surgery could effectively treat low rectal cancer, and short-term recurrence rate is low, but the former has the advantages of refined operation, sufficient visual field exposure, less blood loss and complications, which is safe and reliable with protected intestinal function.
