Single-Incision Laparoscopic Cholecystectomy Using the Marionette Transumbilical Approach Is Safe and Efficient with Careful Patient Selection: A Comparative Analysis with Conventional Multiport Laparoscopic Cholecystectomy.

 The "marionette technique" for transumbilical laparoscopic cholecystectomy (m-TLC) offers improved cosmesis and possibly shorter postoperative recovery for patient undergoing laparoscopic cholecystectomy versus the four-port conventional laparoscopic cholecystectomy (CLC). We compared the outcomes of m-TLC and CLC at a tertiary care facility in New York.  A retrospective chart review was conducted and data on patients who underwent m-TLC and CLC were retrieved. Hospital length of stay (LOS), operative time, and complications were compared between the two groups using linear and logistic regression, as appropriate.  M-TLC group patients were significantly younger, predominantly females with lower body mass index. They were less likely to have previous abdominal surgery and more likely to have noninflammatory pathology (  < 0.05 for all). Nonadjusted LOS (1 vs. 3 days, -value < 0.0001) and operative time (50 vs. 56 minutes, -value = 0.007) were significantly lower among patients who underwent m-TLC; however, there was no significant difference on multivariate analysis. In multivariate analysis, there was no difference in the overall complication rate (odds ratio: 1.63; 95% confidence interval 0.02-2.39).  With careful patient selection, m-TLC offers better cosmesis with comparable safety outcomes.  Level III.
