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.
