Meckel's diverticulum complicated by a congenital intestinal adhesive band: a case report and literature review.

As one of the most common congenital gastrointestinal malformations, Meckel's diverticulum (MD) often has its clinical significance underestimated due to its atypical manifestations. MD may coexist as "concomitant lesions" with various abdominal surgical diseases, increasing the risk of misdiagnosis and missed diagnosis. This article reports an extremely rare case of a 5-month-old male infant with necrotic Meckel's diverticulitis coexisting terminal ileal necrosis and perforation due to a congenital intraabdominal fibrous band. Through a systematic review of the literature on MD with surgical complications associated with other surgical diseases in the PubMed database from 1982 onward (including a total of 12 cases), this study aims to explore the diagnostic challenges and treatment strategies of this condition.
