Coexistence of one Meckel’s diverticulum and two duplication cysts misdiagnosed as three Meckel’s diverticula: a case report

Enteric duplication is a rare congenital disease affecting the entire gastrointestinal tract. Symptoms vary widely and may include abdominal pain, ileus, intestinal bleeding, and hematochezia. Distinguishing enteric duplication from Meckel’s diverticulum can be challenging. Here, we present a case involving both Meckel’s diverticulum and a duplication cyst. We present the case of a 9-month-old Kazakhstani boy who presented with abdominal pain and hematochezia. He underwent laparoscopic surgery in Kazakhstan due to suspected colitis, but no significant findings were observed. The patient then visited Korea, where a CT scan and Meckel’s scan were performed, followed by a second laparoscopic surgery. While the abdominal cavity was clean, three duplication cysts sharing the intestinal wall on the mesenteric side were found, located 75, 110 and 145 cm below the Treitz ligament. The surgery involved two small intestine wedge resections and one small bowel resection with anastomosis. The postoperative course was uneventful. Pathological examination confirmed enteric duplication. We report a rare case of combined intestinal duplication and Meckel’s diverticulum. Enteric duplications can present with diverse clinical symptoms. Recognizing the varied types of digestive enteric duplications is crucial, as each type is associated with different clinical manifestations.
