Abstract
The frequency of obturator hernia is as rare as about 0.4-1.5% of that of strangulated hernia. However, a fact that the onset of the disease concentrates on an aged people may bring us more opportunities to encounter the disease routinely with a progression of aged society. We describe 3 cases of obturator hernia.
Case 1 (70-year-old male), 2 (80, female), and 3(78, female) had right obturator hernias. Two cases were positive to Howsip-Romberg sign, an oppressed symptom of the obturator nerve, but the rest one was negative in which preoperative diagnosis was difficult. Postoperative complication was observed in case 1 which was a formation of abscess on the femur and delayed the treatment period. The reason might be that we had overlooked residual hernia sac to which the necrotized intestinal tract was intussuscepted. Hence, extirpation of hernia sac is necessary for a case of obturator hernia, in which the intestinal tract was necrotized with inflamed hernia sac.
