Laparoendoscopic Single-Site Cholecystectomy: First Experiences with a New Standardized Technique Replicating the...

After reports on laparoendoscopic single-site (LESS) cholecystectomy, concerns have been raised over the level of difficulty and a potential increase in complications when moving away from conventional gold standard multiport laparoscopy due to incomplete exposure and larger umbilical incisions. With continued development of technique and technology, it has now become possible to fully replicate this gold standard procedure through an LESS approach. First experiences with the newly developed technique and instrument are reported.

Fifteen patients presenting with cholelithiasis without signs of inflammation were operated using all surgical steps considered appropriate for the conventional four-port laparoscopic approach, but applied through a single access device. Operation-centered outcomes are presented.

There were no peri- or postoperative complications. Mean operating time was 32.3 minutes. No conversion to regular laparoscopy was required. The critical view of safety was achieved in all cases. Mean skin incision length was 2.2 cm.

The application of a standardized technique combined with the use of a four-port LESS device allows us to perform LESS cholecystectomy, giving us a correct exposure of the structures and without increasing the mean operating time combining previously reported advantages of LESS. A universal trait of any new technique should be safety and reproducibility. This will enhance its applicability by large number of surgeons and to large number of patients requiring cholecystectomy.
