Strangulated Richter's Umbilical Hernia - A Case Report.

Richter's hernia is an abdominal hernia in which part of the circumference of bowel entrapped in the hernial sac. The segment of the entrapped bowel is nearly always the distal ileum but any part of gastrointestinal tract from the stomach to the colon may become incarcerated. The most common sites for Richter's hernia are the femoral ring (71%), deep inguinal ring (23%) and ventral or umbilical hernias (6%). The growing popularity of laparoscopic surgery has led to a new possible site for development of Richter's hernia. In most cases as less than two thirds of the circumference of the bowel wall is involved, the lumen of the gut remains free and thus features of intestinal obstruction are often absent. Richter's hernia is a deceptive entity whose high death rate can be reduced by accurate diagnosis and early surgery. We report a case of strangulated Richter's umbilical hernia in a 36 years old male.
