Incarcerated umbilical Littre’s hernia at the trocar site of a previous laparoscopic surgical procedure

摘要

IntroductionPrevalence of Littre’s hernia (protrusion of a Meckel´s diverticulum through an opening in the abdominal wall) is very low, and Littre’s hernias found in an umbilical site are uncommon. Even rarer are cases of an incarcerated hernia resulting in a surgical emergency. Trocar-site hernias are a relatively common complication after laparoscopic cholecystectomy that develop in association with insertion of wide trocars (usually at the umbilical port).
