(b) Herniated ileum (arrow head) was noted between right pectineus muscle and obturator externus muscle (arrows). An 84-year-old lady presented with a 3-day history of abdominal distention and intermittent colic. She was underweight (body mass index of 12 Kg/m2) and received adhesiolysis for ileus several years ago. Physical examination revealed diminished distal bowel sound and intermittent throbbing pain of right groin area. The kidney, ureter and bladder (KUB) radiography demonstrated small intestine obstruction (Figure 1a). Symptoms persisted despite of prokinetic agents and enema. Abdominal computed tomography (CT) disclosed bowel segment between right pectineus muscle and obturator externus muscle (Figure 1b). Mechanical small intestine obstruction secondary to right obturator hernia was diagnosed, and symptoms relieved after segmental resection of incarcerated ileum via laparoscopy. Intestinal obstruction can be functional or mechanical. Etiologies of mechanical obstruction include postoperative adhesions, hernias, tumors, gallstones, intussusceptions, etc. Obturator hernia, a rare hernia type, is abdominal contents protruding through the obturator foramen. It is more common in the elderly and debilitated woman, also named the “little old lady’s hernia”. Once the diagnosis was available during intestinal obstruction exploration due to lack of specific physical examination, and now it could be detected early and correctly before operation with the assistance of CT, which typically showed herniated segment between pectineus and obturator muscle. Surgical intervention is the most proper treatment option. In typical patients with intestinal obstruction of unknown origin, image studies such as abdominal or pelvis CT should be considered for obturator hernia. *Corresponding author: Cheng-Chieh Yen, Department of Internal Medicine, Ditmansion Medical Foundation Chia-Yi Christian Hospital, No.539, Zhongxiao Rd., East Dist, Chia-Yi City, 60002, Taiwan; Tel: +88652765041; E-mail: [email protected] Citation: Yen CC, Chen CJ (2016) Small Intestine Obstruction Secondary to Obturator Hernia.

Radiology, Pham Ngoc Thach University of Medicine, Ho Chi Minh City, VNM Corresponding author: Huynh Quang Huy, [email protected] Abstract Obturator hernia is a rare condition, characterized by the herniation of an intestinal segment between the obturator and the pectineus muscles through the obturator foramen. Obturator hernias usually occur in the elderly and are less common in males than in females, with a male-to-female ratio of about 1/14. In recent years, the use of diagnostic imaging, especially CT, to determine the causes of intestinal obstruction has been improved to allow for an early and accurate diagnosis, even of obturator hernias, which are extremely rare in male patients. We report a thin elderly man, without a history of surgery and with chronic constipation and an unremarkable Howship-Romberg sign, which was correctly diagnosed before surgery as an obturator hernia using CT. Categories: Radiology Keywords: obturator hernias, computed tomography, intestinal obstruction Introduction Obturator hernia is a rare condition that accounts for approximately 1%-3.9% of all abdominal hernias and 0.4%-1.6% of all cases of mechanical intestinal obstruction [1-5]. In addition, the incidence of obturator hernia is higher in Asia than in the West [3].

This is the development of acute appendicitis within an abdominal hernia. Amyand’s hernia is a rare but important disease to know. This pathology bears the name of the English surgeon, Claudius Amyand, operator of the fi rst appendectomy in the history of medicine in 1735, performed for an acute appendicitis inside an inguinal hernia.

ABSTRACT An obturator hernia is a rare type of hernia and unusual cause of acute intestinal obstruction. The combination of diagnostic difficulty and high mortality rates make obturator hernia a serious diagnosis that can be potentially overlooked. We present a case of an elderly multiparous woman presented at the emergency room with complaints of abdominal distension, pain, vomiting and constipation for the last 4 days. On examination abdominal tenderness with distension was noted. Hernial orifices were normal. A CT and MRI reports were suggestive of right obstructed obturator hernia. Patient underwent emergency exploratory laparotomy. The hernial sac contained a narrow neck Meckel's diverticulum with perforation of proximal ileum. Resection of perforated segment along with Meckel's diverticulum was done and end to end ileo-ileal anastomosis was performed.
