Small bowel obstruction secondary to obturator hernia in an elderly female.

Obturator hernia is an extremely rare type of pelvic hernia with relatively high mortality and morbidity due to delayed diagnosis. Most cases present with acute intestinal obstruction and typically affect elderly, emaciated females. A high index of suspicion is required for early diagnosis and timely surgical intervention. We present a rare case of an 81-year-old female who was initially discharged from the emergency department due to nonspecific symptoms. She represented with clinical features of bowel obstruction and was diagnosed preoperatively with computed tomography imaging identifying a left-sided obturator hernia with a loop of bowel extending through the obturator canal. She was taken to theater for lower midline laparotomy and repair of obturator hernia. Although many cases are identified intraoperatively, we will discuss preoperative means of diagnosis of obturator hernia from examination findings to imaging diagnosis.
