Adult intussusception associated with mesenteric Meckel's diverticulum and antimesenteric ileal polyp

Intestinal intussusception of Meckel's diverticulum, a case report and literature review of the last five years

Meckel's diverticulum is the most common gastrointestinal tract anomaly. It arises from the incomplete closure of the omphalomesenteric conduit, which is a true diverticulum at the antimesenteric border of the ileum. Although the majority of patients are asymptomatic, they can present with inflammation, hemorrhage, intussusception, intestinal obstruction, and perforation, among others; this constitutes an important differential diagnosis for acute abdomen. A 19-year-old female sought medical attention because of intermittent diffuse abdominal pain for two months, nausea, and diarrhea. In the requested imaging tests, tomography, and enterotomography, a diagnosis of Meckel's diverticulum with some degree of intussusception was suggested. The patient underwent elective surgical treatment without complications and was discharged on the second postoperative day with clinical improvement. In this section, we review publications on similar cases published in the last five years.

[Intussusception due to Meckel´s diverticulum in adults: a case report]

Meckel´s diverticulum is the most common congenital anomaly affecting the gastrointestinal tract resulting from failure of involution of the omphalomesenteric duct. This anomaly is most often asymptomatic and may be revealed by a complication, such as intussusception. This study reports the diagnostic pathway and the management of an 18-year-old female patient admitted to the Emergency Department with ileoileal invagination due to Meckel´s diverticulum complicated by occlusion. This study is interesting because it provides an overview of this rare disease whose diagnosis, based on abdominal scanner, must be made early in order to prevent small bowel perforation or necrosis. Bowel resection without desinvagination is the gold standard treatment.
