Meckel's diverticulum in the adult: surgical treatment

Introduction: Management of asymptomatic Meckel's diverticulum (MD) incidentally discovered in adults remains controversial. The aim of this study was to determine if incidental diverticula should be removed. Materials and methods: We reviewed a consecutive series of patients surgically managed from January 1994 to December 2016. Patients were divided into two groups according to symptomatic or asymptomatic diverticula, and characteristics were compared. Results: The study included 66 patients: 30 in the symptomatic group (45%) and 36 in the incidental group (55%). We found 12 females (18.2%), and the ratio male:female was higher in the symptomatic group (14:1 vs. 2.6:1). Patients in the symptomatic group were significantly younger: 41.7 ± 18.1 vs. 54.7 ± 19.8 years (p = .007). MD in the symptomatic group tended to be longer (3.8 ± 1.9 vs. 2.6 ± 0.9 cm; p = .003). A MD-associated malignancy was present in three patients (4.5%), all neuroendocrine tumours. Major postoperative complications occurred in 6.6% of symptomatic patients and 0% within the incidental group, without specific morbidity related to prophylactic surgery. No mortality was observed. Conclusion: Resection of incidentally found Meckel's diverticulum can be made because of benefits outweigh the risks in this high-risk area for cancer.
