Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this trial is to assess the efficacy and safety of single port-access laparoscopic-assisted vaginal hysterectomy. The operative time, weight of the uterus, blood loss and hospital stay will be record, respectively. The pain score is based on the visual analogue scale in which patients record the intensity of their pain 12, 24, and 48 hours after surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Single port laparoscopy is an attempt to further enhance the cosmetic benefits of minimally invasive surgery while minimizing the potential morbidity associated with multiple incisions. Preliminary advances in LESS as applied to urologic and gastrointestinal surgery demonstrate that the techniques are feasible provided that both optimal surgical technical expertise with advanced skills and optimal instrumentation are available. Recently, Lee et al. performed the multiple channel single port-access laparoscopic-assisted vaginal hysterectomy (SPA-LAVH) in 24 patient. All cases but 3 were performed exclusively through a single port. The median operative time, weight of the uterus, and estimated blood loss were 119 minutes (range 90 to 255 minutes), 347 g (range 225 to 732 g), and 400 mL (range 100 to 1000 mL), respectively. The median hospital stay (postoperative day) was 3 days (range 3 to 7). Although there are a limited number of studies demonstrating the feasibility of single-port access laparoscopic-assisted vaginal hysterectomy (LAVH), single-port surgery is "new-old" (i.e., a revisited and unstandardized technique) because the major disadvantage of limited movement caused by collisions of the laparoscopic instruments has been mitigated by the development of multi-channel approaches. Therefore, the investigators used a 2-channel single-port system, which was different from the previously published 3-channel single-port technique11,12 to reduce collisions and aid the assistant in controlling the scope without interfering with the surgeon's instruments. To our knowledge, there are no randomize control trial to evaluate of 2-channel or multiple channel single port laparoscopic surgery in gynecologic disorders. The purpose of this study was to assess the feasibility of 2-channel and multiple-channel single port laparoscopy in the treatment of benign uterine disease.
