Minilaparoscopic versus conventional laparoscopic hysterectomy: results of a randomized trial.

STUDY OBJECTIVE

To compare operative outcomes and postoperative pain of laparoscopic hysterectomy (LH) versus minilaparoscopic hysterectomy (MLH).

DESIGN

Randomized controlled trial (Canadian Task Force Classification I).

SETTING

Tertiary care center.

PATIENTS

Seventy-six women scheduled to undergo a hysterectomy for a supposed benign gynecologic condition.

INTERVENTIONS

Participants were randomly assigned to LH (n = 38) or MLH (n = 38). MLH was performed with use of 3-mm ports. Both patients and assessors of the postoperative outcomes were blinded to the size of port used, and patients' wounds were concealed by standard-size nontransparent dressings.

MEASUREMENTS

Primary outcome was postoperative pain (both rest and incident on coughing and abdominal pain, as well as shoulder pain) by use of a 100-mm visual analogue scale.

MAIN RESULTS

The two groups were similar in terms of operative outcomes. No intraoperative conversion from MLH to both LH and open surgery occurred. No significant difference in pain scores at 1, 3, 8, and 24 hours after surgery between groups was found. Rescue analgesic requirement was similar in the MLH and LH groups (21.1% vs 13.2%, p =.54).

CONCLUSIONS

Ports can safely be reduced in size without a negative impact on the surgeon's ability to perform LH. MLH appears to have no advantage over LH in terms of postoperative pain.
