Resection of Meckel's Diverticulum with a Secondary Pseudo-diverticulum—A Case Report—

Abstract

A 51-year-old woman had sometimes felt abdominal pain, but it had remained un diagnosed. One month earlier, she had complaints of abdominal discomfort and bloating and went to the hospital. Multidetector computed tomography showed a saccular mass, 11 × 7 cm in size, on the wall of the small intestine in the lower right abdomen. Meckel's diverticulum was diagnosed, and single-port laparoscopic surgery was performed. During the operation, a huge, saccular, small intestinal diverticulum was found in the upper left abdomen. The saccular diverticulum in the small intestine had expanded to the contralateral side of the mesentery. Since no other lesion was suspected, the lesion was excised outside the body. Pathological findings showed a diverticulum contralateral to the mesentery, with the muscularis propria ruptured at the base and the submucosal adipose tissue growing in the subserosal layer. It was diagnosed as a huge Meckel's diverticulum with a secondary pseudo-diverticulum because it was continuous from the same part to the area lacking the muscularis propria that occupied most of the diverticulum. Reports of Meckel's diverticulum with a secondary pseudo-diverticulum are rare. A case of Meckel's diverticulum with secondary pseudo-diverticulum resected by single-port laparoscopic ileectomy is reported.
