ABSTRACT
OBJECTIVE: This study aimed to evaluate if placement of transverse cesarean skin incision above or below the overhanging pannus is associated with wound morbidity in morbidly obese patients.
STUDY DESIGN: We identified a cohort of patients with body mass index (BMI) ≥40 kg/m2 undergoing cesarean delivery at a single center from 2017-2020 with complete postpartum records. Data was abstracted after institutional review board exemption, and patients were grouped by low transverse or high transverse skin incision. The primary outcome was a composite of wound infection, fascial dehiscence, incisional hernia, therapeutic wound vacuum, and reoperation. Secondary outcomes included the individual components of the composite, blood transfusion, operative time, and immediate neonatal outcome. T test and χ2 were used for continuous and categorical comparisons. Logistic regression was used to compute adjusted odds ratios for categorical outcomes and linear regression to compare operative times adjusting for factors associated with wound complications and surgical duration respectively.
RESULTS: 328 patients met inclusion criteria: 65 with high transverse (infraumbilical and supraumbilical) and 263 with low transverse (Pfannenstiel) incision. 11% of patients had wound morbidity; high transverse incision was associated with 3.64-fold increased odds of composite wound morbidity (23.1% vs 8%, aOR 3.64, 95% CI 1.52-8.70) and 5.73-fold increased odds of wound infection (13.8% vs. 4.9%, aOR 5.73, 95% CI 1.83-17.96). Time from skin incision to delivery was 1.87 min longer (11.09 vs 14.98 min, β = 1.87, 95% CI 0.17-4.61). There was no significant difference in neonatal outcomes, non-low transverse hysterotomy, or total operative time.
CONCLUSION: High transverse skin incision for cesarean delivery was strongly associated with increased wound morbidity in morbidly obese patients.
