Perioperative Outcomes of Laparoendoscopic Single-Site Surgery (LESS) Versus Conventional Laparoscopy for Adnexal Disease: A Case-Control Study

Objective: This study aimed to evaluate the potential advantages of laparoendoscopic single-site surgery (LESS) approach with respect to conventional laparoscopy. Methods: Thirty LESS patients were matched 2:1 with a previous cohort of 58 patients undergoing conventional laparoscopy for the same type of surgery (controls). Results: Median operative time (38.5 vs 54 minutes; P = .09) and estimated blood loss (20 vs 30 mL; P = .008) were more favorable in patients undergoing LESS treatment compared with those undergoing conventional laparoscopy. Rupture of the cyst was observed in 11 out of 30 cases (36.6%) and 26 of 58 controls (44.8%; P = .46). Median length of stay was 1 day in the cases and 2 in the controls (P = .03). Conclusions: Decreases in operative time, estimated blood loss, or length of stay should not be considered a benefit attributable to LESS; rather it seems there are no differences between these 2 surgical approaches after an adequate selection of patients.
