Analysis of 17 cases underwent laparoscopic rectal cancer surgery with transanal natural orifice specimen extraction and resection / 中华肿瘤杂志

Objective@#To study the feasibility, safety and short-term efficacy of total laparoscopic rectal cancer surgery with transanal natural orifice specimen extraction and resection.@*Methods@#From May 2014 to March 2016, 17 patients with rectal carcinoma were treated by total laparoscopic rectal cancer surgery with transanal natural orifice specimen extraction and resection. The clinical data of these patients was collected and retrospectively analyzed to assess the impact of the operation on postoperative recovery time and the incidence of complications.@*Results@#All operations had been successfully accomplished without conversion to open surgery or conversional laparoscopic-assisted surgery . The median operative time was 105 minutes. The median blood loss was 35 ml. The median proximal and distal margin of tumor is 16 cm and 3.5 cm. The median number of lymph nodes harvest is 21, and the median first bowl movement is 43 hours. The hospitalization after operation is 8 days. No patient underwent abdomen hemorrhage or anastomotic leakage.@*Conclusion@#Laparoscopic rectal cancer surgery with transanal natural orifice specimen extraction and resection appears to be feasible, safe and with promising efficacy for selected patients.

Transanal everted extraction of laparoscopic rectal excision without abdominal incision: a report of 11 cases / 肿瘤研究与临床

Objective To assess the feasibility and short-term effect of transanal everted extraction of laparoscopic rectal excision without abdominal incision.Methods Eleven patients were operated by transanal everted extraction of laparoscopic rectal excision without abdominal incision.Results All the operations were accomplished successfully,the average operative duration was (189.5±25.2) min,the intra-operative blood loss volume was (25.4±9.4) ml,the average time to flatus was (38.9±8.6) h,the average postoperative hospital stay was (12.7±2.5) d,and the number of lymph nodes harvested was 13.5±4.1.There were no post-operative complications.Conclusion The technique of transanal everted extraction of laparoscopic rectal excision without abdominal incision is safe and feasible,but the long-term effects need more observation.
