Postoperative pain after laparoscopic and vaginal hysterectomy for benign gynecologic disease: a randomized trial.

OBJECTIVE: To compare postoperative pain after laparoscopic and vaginal hysterectomy for benign disease. STUDY DESIGN: A prospective randomized trial was designed to compare laparoscopic hysterectomy and vaginal hysterectomy in patients with uterine volume <or=14 weeks of gestation. Postoperative pain was measured using the visual analog scale (VAS) at 1, 3, 8, and 24 hours postoperatively. Intra- and postoperative outcomes were carefully recorded, including the need for postoperative rescue doses of analgesia. RESULTS: A total of 82 patients were enrolled. Patients who underwent vaginal hysterectomy complained of higher postoperative pain at each VAS evaluation (VAS-1 hour, P < .0001; VAS-3 hour, P < .0001; VAS-8 hour, P < .0001; VAS-24 hour, P = .0003) with a higher need for rescue analgesia (P < .0001) and a longer hospitalization (P = .001). The other perioperative characteristics were comparable between the 2 groups. CONCLUSION: Laparoscopic hysterectomy provides an advantage over vaginal hysterectomy in terms of postoperative pain, need for rescue analgesia and hospital stay, with similar perioperative outcomes
