Single-incision laparoscopic surgery (SILS), or laparoendoscopic single-site surgery, has been employed in various fields to minimize traumatic effects over the last two decades. Single-incision laparoscopic cholecystectomy (SILC) has been the most frequently studied SILS to date. Hundreds of studies on SILC have failed to present conclusive results. Most randomized controlled trials (RCTs) have been small in scale and have been conducted under ideal operative conditions. The role of SILC in complicated scenarios remains uncertain. As common bile duct exploration (CBDE) methods have been used for more than one hundred years, laparoscopic CBDE (LCBDE) has emerged as an effective, demanding, and infrequent technique employed during the laparoscopic era. Likewise, laparoscopic biliary-enteric anastomosis is difficult to carry out, with only a few studies have been published on the approach. The application of SILS to CBDE and biliary-enteric anastomosis is extremely rare, and such innovative procedures are only carried out by a number of specialized groups across the globe. Herein we present a thorough and detailed analysis of SILC in terms of operative techniques, training and learning curves, safety and efficacy levels, recovery trends, and costs by reviewing RCTs conducted over the past three years and two recently updated meta-analyses. All existing literature on single-incision LCBDE and single-incision laparoscopic hepaticojejunostomy has been reviewed to describe these two demanding techniques.
Core tip: Single-incision laparoscopic surgery (SILS) has been employed in various fields to minimize traumatic effects. Single-incision laparoscopic cholecystectomy (SILC) has been the most widely studied SILS approach to date. Hundreds of studies on SILC have failed to present conclusive results. Only a small number of studies on single-incision laparoscopic common bile duct exploration (SILCBDE) and single-incision laparoscopic hepaticojejunostomy (SILH) have been published. This paper serves as an updated review of SILC approaches and as the only existing review on SILCBDE and SILH. Our findings underscore the safety and efficacy of SILC, SILCBDE, and SILH and potential benefits and disadvantages of these methods in relation to conventional multi-incision laparoscopic surgery approaches.
