title: Single Incision Laparoscopic Cholecystectomy Performed Via the "Marionette" Technique Shows Equivalence in Outcome and Cost to Standard Four Port Laparoscopic Cholecystectomy in a Selected Patient Population.
abstract: The aim of our study is to compare single incision laparoscopic cholecystectomy (SILC) performed using the "marionette" technique (m-SILC), to the standard four-port technique [four-port laparoscopic cholecystectomy (4PLC)]. Patient information was extracted from a prospectively maintained database (n = 188). Our primary endpoint was operative costs (determined by operating time and instruments used). Secondary endpoints were length of stay, operative time, blood loss, and postoperative complication rates. Univariate and adjusted multivariate analysis was used to compare the outcomes. There were a total of 188 patients for this study. Gender, body mass index, American Society of Anesthesiologists class, and resident participation were similar. Patients undergoing m-SILC were younger (43.8 vs 49.8 years old), less likely to have cholangiogram (32% vs 54%), and were more likely to undergo cholecystectomy for chronic cholecystitis (73.3% vs 52%). In univariate analysis, cholecystectomy performed by the "marionette method" as compared with the 4PLC was associated with shorter operative time (67 vs 59 minutes respectively) and shorter hospital stay (1.2 vs 2.08 days respectively). In multivariate analysis, SILC was associated with shorter hospital stay and comparable operative time, blood loss, and postoperative complications. Instrumentation cost was less in SILC (by $94). SILC done by an experienced surgeon with the "marionette" technique on a carefully selected population shows a statistically significant cost benefit while maintaining clinically comparable outcomes to the standard 4PLC.
