Clinical analysis of 18 cases of obturator hernia.

INTRODUCTION: Obturator hernia is a relatively rare type of abdominal external hernia.The diagnosis is often delayed because of its rarity and nonsepcific symptoms and signs. PATIENTS AND METHODS: Retrospective study of 18 patients undergoing surgery for obturator hernia in a 11-year period. RESULTS: 15 female and 3 male patients were recorded. Low body mass index (BMI) was the common predisposing factor. Accurate preliminary diagnosis were made only in 8 patients with support of timely computed tomography (CT) scans. The rate of strangulated hernias was 33.33% (6/18)and intestinal resection was required in 4 cases. 11 patients underwent open surgery while 7 received laparoscopic surgery. Simple closure of the hernia defect or hight ligation was performed in 12, mesh repair in 6. No serious operative complications was observed. CONCLUSIONS: Obturator hernia should be included in the differential diagnosis of intestinal obstruction of unknown origin, especially in elderly women with low BMI. Early surgical intervention is imperative to avoid intestinal resection and reduce complications. Laparoscopy has a tendency to rapid recovery but has its limits.
