Abstract
A 35-year-old man with lower abdominal pain was admitted to our hospital. Abdominal computed tomography revealed a 2-cm funic structure connected to the small intestine suggesting inflammatory Meckel's diverticulum. At first, conservative therapy with antibiotics was attempted, and the patient's abdominal pain temporarily improved before recurring later. Laparoscopic surgery was performed. Meckel's diverticulum with severe inflammatory change was detected in the ileum about 120 cm proximal to the ileal end, and was resected using an endoscopic linear stapler. Histological findings showed that the acute inflammation was limited to Heinrich type I ectopic pancreatic tissue within the tip of the diverticulum. There are only two clinical reports of ectopic pancreatitis in a Meckel's diverticulum in the literature and this is the first report of treatment by laparoscopic surgery, highlighting the extreme rarity of this clinical entity.
