Abstract
We report a case of metachronous bilateral obturator hernia obstruction with contralateral onset occurring nine days after initial surgery. An 81-year-old woman was re-admitted due to a small intestinal obstruction related to a left obturator hernia which occurred nine days after a hernioplasty for a right obturator hernia. It was thought that she might have already had the contralateral obturator hernia at the time of the initial operation. Retrospectively, it was noted that the abdominal pelvic CT done at the time of the first operation showed a left soft tissue density area with a space of more than 10 mm between the pectineus and the obturator muscles, thus providing evidence of left obturator hernia. In patients with a unilateral obturator hernia, we a contralateral hernia should be ruled out. Pelvic CT may be helpful in such cases in order to help plan the operative procedure.
