Abstract：Objective To compare the effect of laparoscopy and laparotomy radical resection in treating low rectal cancer.Methods Totally 118 patients with low rectal cancer from March 2012 to March 2014 underwent laparoscopy radical resection (laparoscopy group, 65 cases) and laparotomy radical resection (laparotomy group,53 cases).The operation duration, blood loss, volume of abdominal drainage, time of gastrointestinal recovery,length of hospitalization, number of lymph nodes dissected, rate of sphincter-preserving, postoperative complications were analyzed and compared between the two groups.Results There were no significant differences regarding operation duration and number of lymph nodes dissected between groups (P ＞ 0.05).The volume of bleeding and abdominal drainage were less, time of gastrointestinal recovery and length of hospitalization were shorter in laparoscopy group than those in laparotomy group [(92 ± 51) ml vs (143 ± 83) ml, (169 ±45) ml vs (195 ±58) ml, (2.5±0.7) dvs (3.3±0.5) d, (8.7±1.3) dvs (9.6±2.1) d] (P＜0.05).The operation was finished successfully in all the 65 patients in laparoscopy group, including 63 anterior resection and 2 abdominoperineal resection;10 cases received abdomino-perineal resection in laparotomy group.The rate of sphincterpreserving in laparoscopy group was significantly higher than that in laparotomy group [96.9％ (63/65) vs 81.1％ (43/53)] (P ＜ 0.05).Four cases had anastomotic leakage and 8 cases had increased frequency of stool in laparoscopy group, 3 cases had anastomotic leakage and 7 cases had increased frequency of stool in laparotomy group;all the patients got recovery after conservative treatment.No other complications, such as ureteral ingury,dysuresia, fecal incontinence occurred in both groups.Conclusion Laparoscopy radical resection is safer and feasible with less injury and shorter recovery time compared with laparotomy in treating low rectal cancer, while without increasing the incidence of postoperative complications;in addition, laparoscopy radical resection is superior to laparotomy radical resection regarding sphincter-preserving.
