Nonclosure of the visceral and parietal peritoneum at caesarean section: a randomised controlled trial.

OBJECTIVE

To assess the short term morbidity of nonclosure of the peritoneum at caesarean section.

DESIGN

Women undergoing a lower segment caesarean section were randomly allocated to either closure or nonclosure of the visceral and parietal peritoneum.

SETTING

Tertiary Care University Hospital of Geneva.

MAIN OUTCOME MEASURES

Length of post-operative hospital stay. Other outcomes include maternal pain as assessed by both a visual analogue scale and the amount of post-operative analgesics administered, post-operative ileus, and febrile morbidity. Operative time was recorded.

RESULTS

We allocated 137 women to the nonclosure group and 143 to the closure group. Population characteristics were similar between groups. The mean length of hospital stay was 6.5 (SD 1.9) days for the nonclosure group and 6.8 (SD 2.2) days for the closure group (P = 0.21). No differences were found in the level of post-operative pain, the number of analgesic doses given, nor in the proportion with febrile morbidity. Post-operative ileus resolved later in the closure group (P = 0.006). The mean operative time was shorter by 6 min (P = 0.006) in the nonclosure group.

CONCLUSIONS

Short term post-operative morbidity and maternal pain are not increased by a shorter and more simple surgical procedure in which the peritoneum is left unsutured.
