A comparison of clinical and surgical outcomes between laparo-endoscopic single-site surgery and traditional multiport laparoscopic surgery for adnexal tumors

OBJECTIVE: The purpose of this study was to compare clinical and surgical outcomes between laparo-endoscopic single-site (LESS) surgery and traditional multiport laparoscopic (TML) surgery for treatment of adnexal tumors. METHODS: Medical records were reviewed for patients undergoing surgery for benign adnexal tumors between January 2008 and April 2012 at our institution. All procedures were performed by the same surgeon. Clinical and surgical outcomes for patients undergoing LESS surgery using Glove port were compared with those patients undergoing TML surgery. RESULTS: A review of 129 patient cases undergoing LESS surgery using Glove port and 100 patient cases undergoing TML surgery revealed no significant differences in the baseline characteristics of the two groups. The median operative time was shorter in the LESS group using Glove port at 44 minutes (range, 19-126 minutes) than the TML group at 49 minutes (range, 20-196 minutes) (P=0.0007). There were no significant differences between in the duration of postoperative hospital stay, change in hemoglobin levels, pain score or the rate of complications between the LESS and TML groups. CONCLUSION: LESS surgery showed comparable clinical and surgical outcomes to TML surgery, and required less operative time. Future prospective trials are warranted to further define the benefits of LESS surgery for adnexal tumor treatment.

Transumbilical laparo-endoscopic single-site partial nephrectomy: An initial clinical experience of 2 cases / 第二军医大学学报

Objective: To summarize our experience and operative techniques of transumbilical laparo-endoscopic single-site partial nephrectomy (TLSPN). Methods: TLSPN was performed on two patients for the right kidneys in August and September of 2009. Results: The operation was successfully done in both cases, with an additional trocar of 5 mm to retract the liver. The operation time was 255 min and 240 min; the time periods of renal artery occlusion were 48 min and 40 min; and the intraoperative blood losses were 100 ml and 50 ml. None of the patients received blood transfusion or antalgic. The drainage was removed 9 days and 5 days after operation, and the postoperative hospital stays were 13 and 12 days. Conclusion: TLSPN is a safe and effective method with less trauma. However, special instruments are needed for the procedure, and the suture and knotting are somewhat difficult. An assistant trocar is needed for the procedure for the right kidney.
