Laparoscopic-assisted vaginal hysterectomy: a case control comparative study with total abdominal hysterectomy

We compared laparoscopic-assisted vaginal hysterectomy (LAVH) with total abdominal hysterectomy (TAH) in a case control study that evaluated length of operation, blood loss, length of hospital stay, drug requirements for pain, and postoperative pain and activity levels. Of 81 women who underwent nonradical hysterectomy for a primary diagnosis of pelvic pain between June 1 and December 31, 1992, 19 who underwent each procedure were chosen for inclusion in the study. Patients were matched in a case control manner with age, weight, diagnosis, and uterine weight. All 38 hysterectomies were completed without incident. When indicated, unilateral or bilateral oophorectomies were performed. The average surgery time for LAVH was 144 minutes and for TAH 98 minutes, a significant difference (p <0. 005). There were no significant differences between estimated blood loss and change in hemoglobin from preoperative levels to postoperative day 1 levels between the groups. Women having TAH reported significantly more pain after their release from the hospital. There was no significant difference in pain during hospitalization apparently because patients who had TAH self-medicated to maintain acceptable levels. That group in fact used an average of 436 mg meperidine during their hospital stay, significantly more than the 197 mg used by the LAVH group (p <0.005). The length of stay was 2.125 days for LAVH and 3.542 days for TAH (p <0.001). On a scale of 1 to 10 (10 being complete normal activity) the activity level of women undergoing LAVH was 9.2 by day 14 compared with 6.4 for those having TAH (p <0.005). By the sixth postoperative week the latter group reported an activity level of only 8.5, indicating that the ability to function is much more severely limited after TAH than LAVH.
