Abstract
BACKGROUND: The worldwide incidence of birth by Caesarean Section (CS) is rising. Many births after a previous CS are by repeat surgery, either by an elective CS or after a failed trial of labour. Adhesion formation is associated with increased maternal morbidity in patients with repeat CSs. In spite of large-scale studies the relation between the incidence of adhesion formation and CS surgical technique is unclear. This study aims to assess maternal and neonatal morbidity and mortality after repeat CSs in a rural hospital in a low-income country (LIC) and to analyse the effect of surgical technique on the formation of adhesions. METHODS: A cross-sectional, retrospective medical records study of all women undergoing CS in Ndala Hospital in 2011 and 2012. RESULTS: Of the 3966 births, 450 were by CS (11.3%), of which 321 were 1(st) CS, 80 2(nd) CS, 36 3(rd) CS, 12 4(th) and one 5(th) CS (71, 18, 8, 3 and 0.2% respectively). Adhesions were considered to be severe in 56% of second CSs and 64% of third CSs. In 2(nd) CSs, adhesions were not associated with closure of the peritoneum at 1(st) CS, but were associated with the prior use of a midline skin incision. There was no increase in maternal morbidity when severe adhesions were present. Adverse neonatal outcome was more prevalent when severe adhesions were present, but this was statistically non-significant (16% vs 6%). CONCLUSIONS: Our results give insight into the practice of repeat CS in our rural hospital. Adhesions after CSs are common and occur more frequently after midline skin incision at 1(st) CS compared to a transverse incision. Reviewing local data is important to evaluate quality of care and to compare local outcomes to the literature.
