TORRES PENA, Rafael et al. Single-port access laparoscopic cholecystectomy. Rev Cubana Cir [online]. 2013, vol.52, n.4, pp. 245-256. ISSN 0034-7493.

Introduction: single-port access laparoscopic surgery is basically performed through one incision (15-18mm) in which several trocars or a multi-port device are placed. Most of these procedures have two main limitations: accumulation and interference of surgical instruments and the reduction of the triangulation quality and of the surgical area exposure. Objectives: to describe the surgical technique and to evaluate the initial results of a new modality of laparoscopic cholecystectomuy through a single-port access. Methods: the surgical technique developed by the authors was detailed, which is based in the use of a laparoscope with working channel, new laparoscopic instruments and a retraction system supported on two specially designed 1.2mm retractors. The study was conducted from December 2010 through August 2012 and included 29 selected patients. The inclusion criteria were uncomplicated symptomatic disease, body mass index lower than 30 and not more than three calculi with less than 20mm diameter. Results: the procedure was performed satisfactorily (critical view) in 93.1% of cases. Eighty six percent were women, the average age was 36 years (range, 17-57), the average body mass index was 24.4 (range, 21.9-27.5) and the average surgical time was 62 minutes (range, 41-80). The rupture of a vesicular wall was reported during extraction but no consequences occurred during follow-up. Conclusions: the suggested technique avoids accumulation and interference of the surgical instruments and optimizes the quality of the surgical area exposure. It may be safely performed in selected patients, although it demands more surgical experience from the surgeon.
