Purpose
Natural orifice transluminal endoscopic surgery (NOTES) is a novel technique that aims at reducing or abolishing skin incisions and potentially also postoperative pain. The purpose of this study was to analyse operative and long-term results of a series of hybrid transvaginal cholecystectomy.
Materials and methods
Between July 2007 and May 2009, transvaginal NOTES cholecystectomy for symptomatic cholelithiasis was performed by a hybrid technique in 18 women (mean age 54 years), including four women with a body mass index >30 kg/m2. Dissection was conducted in the first four cases by a round-tip unipolar electrode (UE) introduced through the operative channel of the endoscope coming from the vagina and in the last 14 cases by a ultrasonic scalpel (US) introduced through a 5-mm abdominal port. The short-term outcomes and the long-term results of the two methods were compared.
Results
The transvaginal approach entailed no intraoperative complication and no conversion. The overall mean duration of procedures was 75 min (range 40–190). In the first four cases (UE), the operating time was 148 min (range 140–190), whilst in the last 14 (US), it was considerably shorter, 53 min (range 40–60, p < 0.01). We experienced one biliary leak in the UE group, whilst morbidity with US was nil (p < 0.005). The biliary leak healed in 7 days with nasobiliary drainage. No other complications were encountered in either group. The mean follow-up was 12 months (range 1–22), and none of the patients has complained of dyspareunia or other colpotomy-related complications so far.
Conclusions
Until specifically designed endoscopic tools are available for NOTES, the hybrid technique with US dissection conducted through a 5-mm port should be preferred in transvaginal cholecystectomy in order to shorten the duration of surgery and make this approach effective, safe and reproducible. After a mean follow-up of 1 year, none of our patients has complained of any problem related to transvaginal approach.
