Postoperative pain after conventional laparoscopy and laparoendoscopic single site surgery (LESS) for benign adnexal disease: a randomized trial

Objective: To compare postoperative pain after laparoendoscopic single-site surgery (LESS) approach with conventional multiaccess laparoscopy (LPS). Study Design: Prospective randomized trial. Setting: University hospital. Patient(s): Benign adnexal disease. Intervention(s): Postoperative pain was measured by using the visual analog scale (VAS) at 20 minutes, 2 hours, 4 hours, and 8 hours after surgery. The need for postoperative rescue doses of analgesia was also recorded. Main Outcome Measure(s): Pain after surgery. Result(s): A total of 60 patients were enrolled. Within 8 hours, patients who underwent conventional LPS complained of statistically significant greater postoperative pain at VAS evaluation than those undergoing LESS, both at rest and after Valsalva maneuver, with a higher need for rescue analgesia. Conclusion(s): LESS provides an advantage over conventional multiaccess LPS in terms of postoperative pain and need for rescue analgesia, with similar perioperative outcomes.
