Study Objective:
To estimate whether closed-suction drainage of the pelvis after laparoscopic-assisted vaginal hysterectomy reduces the risk of postoperative morbidity.
Design:
Prospective, randomized study (Canadian Task Force classification 1).
Setting:
Teaching medical center.
Patients:
Three hundred twenty-four women.
Intervention:
Laparoscopic-assisted vaginal hysterectomy.
Measurements And Main Results:
The 160 women in group 1 had closed-suction (Jackson-Pratt) drains inserted into the peritoneal cavity and cul-de-sac, whereas the 164 in group 2 had no drains. Postoperative time to flatulence, hemoglobin, analgesic requirements, duration of hospital stay, rehospitalization, complications, febrile morbidity, and infection were studied. No statistically significant differences were seen between groups in demographics, outcome measures, postoperative infectious morbidity, or complications. The small power value may mean that no true differences existed for most tests. A statistically significant difference in analgesic requirement was found, with more oral analgesics taken by women in group 2.
Conclusion:
Prophylactic surgical drainage may not be necessary to prevent postoperative morbidity after laparoscopic-assisted vaginal hysterectomy when prophylactic and postoperative antibiotics are given. A drain still has its role in gynecologic laparoscopy in selected women, such as in those with persistent ooze from raw surfaces, bowel injury, or frank pus in the abdomen.
