Abstract Purpose To detect risk factors on clinical characteristics and multidetector computed tomographic (MDCT) findings for predicting bowel obstruction in patients with obturator hernia. Methods We retrospectively reviewed 47 patients who had an obturator hernia diagnosed by MDCT and/or surgery. The patients were divided into obstruction and non-obstruction group based on the presence or absence of bowel obstruction on MDCT images. Uni- and multivariate analyses were performed to identify risk factors for predicting bowel obstruction. Results There were 26 patients (55.32%) in the obstruction group and 21 patients (44.68%) in the non-obstruction group. Patients in the obstruction group were older (P = 0.002) and had more women (P = 0.033) and lower body mass index (BMI) (P = 0.0001) than patients in the non-obstruction group. The non-obstruction group suffered fewer bowel obstruction symptoms (P = 0.0001), Howship-Romberg (HR) sign (P = 0.012), deaths (P = 0.008) and major postoperative complications (P = 0.047). The hernia sac in the obstruction group had greater mean major diameter (P = 0.0001) and volume (P = 0.001) than those in the non-obstruction group. Multivariate analysis showed that age [odds ratio (OR) 1.18, 95% confidence interval (CI) 1.00–1.39, P = 0.046] and major diameter of hernia sac (OR 68.17, 95% CI 4.52–1027.70, P = 0.002) were independent risk factors associated with bowel obstruction in patients with obturator hernia. Conclusions Patient’s age and major diameter of hernia sac are independent risk factors resulting in bowel obstruction in patients with obturator hernia. Obturator hernia repair before bowel obstruction development may result in better outcomes and fewer postoperative complications.
