ABSTRACT
The ligation of dorsal venous complex (DVC) is a very important procedure during laparoscopic radical prostatectomy (LRP). Inaccurate DVC ligation may lead to severe bleeding or postoperative incontinence. We, therefore, designed the DVC pretightening technique to facilitate this procedure. The 32 involved patients with localized prostate cancer underwent LRP between July 2017 and October 2018. All of the patients received DVC pretightening technique. A laparoscopic intestinal clamp was used to narrow and strain DVC. The needle passage was limited between the bone and clamp. The ligation time, DVC-related blood loss, and continence data were recorded. The ligation of DVC in 32 patients was performed with DVC pretightening technique. Every suture was completed with one attempt. The mean ligation time was 2.7 ± 1.0 min. The DVC-related blood loss was 2.0 ± 1.3 ml. The 3-month continence rate was 81.3% (26/32). Positive margin rate was 9.4% (3/32). In conclusion, the DVC pretightening technique simplified the ligation of DVC during LRP. It is a safe and reliable technique. However, large-sample randomized controlled trials are still required to confirm the advantage of the new method in improving mean ligation time, DVC-related blood loss, continence rate, and positive margin rate.

Objective To observe and compare the safety and short-term outcomes of laparoscopic surgery (LS)versus conventional open surgery(OS)for stage Ⅱor Ⅲ rectal cancer(RC). Methods One hundred and six patients with stage ⅡorⅢRC were divided into LS group(n=53)and OS group(n=53)according to the random double blind method. The related outcomes of two groups were compared ,including surgical duration , intraoperative blood loss , length of incision , distal margin length , proximal margin length , the number of lymph node dissection,residual cancer rate,exhaust time,first ambulation time,and postoperative hospital stay. Results Intraoperative blood loss,length of incision,postoperative hospital stay,exhaust time and the first ambu-lation time in LS group were significantly different from those in OS group (P < 0.05 for all comparisons). And there were no significant differences between the two groups in surgical duration ,the number of lymph node dissec-tion,distal margin length,proximal margin length and residual cancer rate(P > 0.05). Conclusions Laparo-scopic technology is safe and feasible in treating rectal carcinoma,with less trauma,quicker recovery,and shorter hospital stay.
