Scientific paperForty-three cases of obturator hernia
Section snippets
Methods
From 1968 to 1999, 43 cases of obturator hernias were diagnosed and treated at Tokyo Metropolitan Geriatric Hospital. All cases were reviewed retrospectively with respect to sex, age, body weight on admission, and pregnancy history. In 1987, CAT was introduced for the diagnosis of obturator hernias at our institute and was performed particularly in elderly and emaciated female patients who had intestinal obstruction.
To evaluate the effect of CAT, we divided 43 patients with obturator hernia
Patient characteristics and clinical symptoms
The 2 groups were comprised of 41 women and 2 men (female:male ratio 20.5:1). The patients ranged in age from 65 to 91 years (mean 80.2). Nine patients had a history of previous abdominal surgery (n = 4 in group A, n = 5 in group B), and 34 patients (81%) had no history of such surgery (n = 19 patients in group A, n = 15 in group B). There were no statistically significant differences between groups A and B regarding mean age (80.1 vs 80.3 years), body weight (34.2 vs 36.5 kg), number of
Comments
The total number of obturator hernias in this series represented 1.0% (43 of 4266) of all hernias repaired at our institution. Obturator hernia occurs in an older age group, and the mean age of patients in this series was 80.2 years. Multiparity and recent weight loss are important etiologic factor in the development of obturator hernia. Women are affected nine times more frequently than men because of their broader pelvis, larger obturator canal, and history of pregnancy [5], [6], [7]. In our

The largest reported case series of obturator hernia constituted only 43 patients (6). These hernias are six times more likely to occur in elderly thin women in their 7th and 8th decades.
