Abstract
A 32–year–old male with right lower abdominal pain was admitted to our hospital. The patient received a preoperative diagnosis of acute appendicitis, and underwent appendectomy. Since the patient had right lower abdominal pain as well as fever on the 12 th postoperative day, he received emergency reexploration due to the suspicion of intra–abdominal abscess. During the second operation, we observed an inflammatory long band as well as necrotic cystic mass with abscess. The mass including the affected ileum was resected. The histopathological report indicated that the mass was due to the inflammation of large Meckel's diverticulum.
Our present case was an extremely rare example of Meckel's diverticulum with a band–like shape of 10 cm in length. We think that it is very difficult to make a precise diagnosis of diverticulm even during laparotomy. Therefore, we should consider the existence of Meckel's diverticulum like our present case when we do not observe the typical macroscopical findings of appendicitis.
