Objective To compare the clinical efficacy between laparoscopic resection and open resection for rectal cancer and explore the safety and feasibility of laparoscopic resection.Methods The clinical data of 68 patients suffering rectal cancer resection were analyzed retrospectively.The patients were divided into laparoscopic group(31 cases)and open group(37 cases)according to the operation method.Results There was no significant difference in the number of lymph nodes dissection and postoperative complication rate between two groups(P ＞ 0.05).The operation time in laparoscopic group was significantly longer than that in open group [(162.03 ±39.78)min vs.(142.70 ±30.29)min].The bleeding in laparoscopic group was less than that in open group [(153.23 ± 58.94)ml vs.(247.46 ± 92.51)ml].The recovery of intestinal function time and hospital stay in laparoscopic group was shorter than that in open group [(51.39 ±7.28)h vs.(77.81 ±11.68)h,(12.65 ±2.24)d vs.(15.29 ±3.11)d].And there were significant differences between two groups(P ＜ 0.05 or ＜ 0.01).Conclusion Laparoscopic resection for rectal cancer can achieve short-term clinical efficacy similar to the traditional open surgery,and advantages in terms of safety and postoperative recovery worthy of further promotion.

【Objective】 To share the technical key points and experience of transvesical robot-assisted radical prostatectomy (TvRARP). 【Methods】 The clinical data of 13 patients with prostate cancer (PCa) receiving TvRARP during Nov.2021 and May 2022 were collected. The operation time, estimated blood loss, blood transfusion rate, catheter removal time, postoperative length of hospital stay, immediate urinary continence rate, postoperative IIEF-5 score and perioperative complications were evaluated. 【Results】 The operation time was (142±39) min, estimated intraoperative blood loss was (76±40) mL, and no transfusion was needed. The median postoperative IIEF-5 score was 16 (12-22), hospital stay 3 (2-5)days, and catheter removal time 7(5-14)days. Of all 13 patients, 12(92.3%) achieved immediate urinary continence at the removal of catheter. There were no postoperative complications of Clavien Ⅲ and above. Clavien Ⅰ-Ⅱ complications were observed in 4 patients (30.8%). 【Conclusion】 TvRARP is feasible and safe for selected patients with clinically localized PCa, which can ensure promising postoperative urinary continence and preserve erectile functional.
