Case report: Diverticulitis complicating a giant Meckel's divertuculum

In this paper, we discuss a unique case of diverticulitis in which the patient presented a giant Meckel's diverticulum.

The patient was a 44 year old male whose medical history included a laparoscopic gastric bypass four years before the finding, and chronical high blood pressure. The patient came to the emergency department with an abdominal pain and elevated acute-phase reactants. An abdominal CT revealed a 17 cm long Meckel's diverticulum with signs of severe inflammation. The patient was then taken to the operating room, and subjected to a 4 cm ileum resection, including the entire diverticulum, with a manual end-to-end anastomosis.

Although Meckel's diverticulum is the most common congenital abnormality of the intestinal tract, it is unusual for it to cause symptoms in adults. However, when a patient arrives at the emergency department with a complicated Meckel's diverticulum, an early diagnosis is essential to prevent serious complications, such as perforation of the diverticulum and subsequent peritonitis. The presence of a giant diverticulum is an extremely rare condition. There are few publications to date, but these diverticula are associated with more complications, presenting a higher risk of torsion, volvulus or intestinal obstruction. This paper include a bibliographic review of existing studies on etiopathogenesis, and the diagnosis and treatment of complicated Meckel's diverticulum, particularly in its giant variant.

Although Meckel's diverticulitis is a rare entity, it can appear as an acute abdomen. An early diagnosis and treatment to prevent subsequent complications is essential to ensure an optimal recovery.
