Adhesion barriers and intraperitoneal or uterine infections after cesarean section: A retrospective cohort study

Published:October 07, 2022DOI:



      Intraperitoneal adhesion is a common complication of cesarean section, and adhesion barriers are often used to prevent postoperative adhesion. However, the association between the use of adhesion barriers and infections after cesarean section remains unknown. This study aimed to evaluate the association.


      Using the administrative claims database of a single prefecture in Japan, we identified all patients who underwent cesarean section from June 2014 to February 2019. A multivariable logistic regression model fitted with a generalized estimating equation was used to compare the postoperative outcomes between patients who received intraperitoneal adhesion barriers during cesarean section and those who did not. The primary outcome was intraperitoneal or uterine infections within 3 months after cesarean section, including intraperitoneal abscess, pelvic inflammatory disease, peritonitis, uterine wound infection, endometritis, and adnexitis.


      A total of 1,392 patients with 1,498 cesarean section cases were reviewed. Adhesion barriers were used in 1,153/1,498 (77.0%) cases. One hundred and fourteen (9.9%) intraperitoneal or uterine infections occurred in the group with and 15 (4.3%) in the group without adhesion barriers. The proportion of intraperitoneal or uterine infections was significantly higher in the group with than in the group without adhesion barriers (9.9% and 4.3%, respectively; adjusted odds ratio = 2.59; 95% confidence interval, 1.40–4.77; P = .002).


      The use of adhesion barriers was associated with an increase in intraperitoneal or uterine infections after cesarean section.
