A Case of Adenocarcinoma of Meckel's Diverticulum Resected by Laparoscopy-assisted Surgery

Abstract

A 69-year-old man was admitted to the hospital with the complaint of epigastric pain. Abdominal CT revealed a tumor in the ileum, and PET/CT showed high uptake in the tumor and mesenteric lymph nodes. Laparoscopy-assisted surgery was performed. The tumor in Meckel's diverticulum was resected with the diverticulum. The intraoperative diagnosis based on frozen-section examination was adenocarcinoma of Meckel's diverticulum. Segmental resection of the ileum with lymph node dissection was performed. The patient received postoperative adjuvant chemotherapy with mFOLFOX6 for 6 months and is currently alive, 30 months after the surgery, without recurrence.

Adenocarcinoma of Meckel's diverticulum is extremely rare and preoperative diagnosis is very difficult due to the anatomical characteristics of this region. Laparoscopy-assisted surgery is useful for the diagnosis and resection of adenocarcinoma of Meckel's diverticulum.
