A randomized controlled trial of uterine exteriorization versus in situ repair of the uterine incision during cesarean delivery

Objective

To compare extra-abdominal repair of the uterine incision at cesarean delivery with in situ repair.

Methods

The present study was a double-blind randomized controlled trial conducted at a university hospital in Egypt during 2012–2013, and included women with an indication for cesarean delivery. Extra-abdominal repair was used in group 1 (n = 500) and in situ repair in group 2 (n = 500). The primary outcome measure was the surgery duration.

Results

Surgery duration was significantly longer in group 1 than group 2 (49.9 ± 2.3 minutes vs 39.9 ± 1.8 minutes; P < 0.001). More patients in group 1 than in group 2 had postoperative moderate-to-severe pain (165 [33.0%] vs 115 [23.0%]; P = 0.001) and needed additional postoperative analgesia (100 [20.0%] vs 50 [10.0%]; P < 0.001). Moreover, mean time to bowel movement was longer in group 1 than in group 2 (17.0 ± 2.7 hours vs 14.0 ± 1.9 hours; P < 0.001).

Conclusion

In situ uterine closure is more advantageous than extra-abdominal repair in terms of surgery duration, postoperative pain and need for additional analgesia, and return of bowel movement.ClinicalTrials.gov:NCT01723605
