Objective: This review aimed to determine the role of single-incision laparoscopic surgery (SILS) in abdominal and pelvic operations.
Data Sources: The Medline, EMBASE, and PsycINFO databases were systematically searched until October 2009 using "single-incision laparoscopic surgery" and related terms as keywords. References from retrieved articles were reviewed to broaden the search
Study Selection: The study included case reports, case series, and empirical studies that reported SILS in abdominal and pelvic operations.
Data Extraction: Number of patients, type of instruments, operative time, blood loss, conversion rate, length of hospital stay, length of follow-up evaluation, and complications were extracted from the reviewed items
Data Synthesis: The review included 102 studies classified as level 4 evidence. Most of these studies investigated SILS in cholecystectomy (n=34), appendectomy (n=24), and nephrectomy (n=17). For these procedures, operative time, hospital stay, and complications were comparable with those of conventional laparoscopy. Conversion to conventional laparoscopy was seldom performed in cholecystectomy (range, 0-24%) and more frequent in appendectomy (range, 0-41%) and nephrectomy (range, 0-33%).
Conclusion: The potential benefits of SILS include superior cosmesis and possibly shorter operative time, lower costs, and a shortened time to full physical recovery. Careful case selection and a low threshold of conversion to conventional laparoscopic surgery are essential. Multicenter, randomized, prospective studies are needed to compare short- and long-term outcome measures against those of conventional laparoscopic surgery.
