Background: The aim of this study was to assess the indication for surgical treatment of incidentally discovered Meckel's diverticulum (MD) on the basis of clinical and histological features. Methods: The charts of patients undergoing surgery for MD were analysed. Two groups were identified: (1) patients who had incidentally discovered MD resected (incidental MD, IMD) and (2) patients who received first-line surgery for a complicated MD (CMD). Demographics and intraoperative and post-operative outcomes were compared. Histological findings were also analysed and compared. Results: Sixty-five patients were included in the study. IMD was observed in 39 patients (60%), while CMD was observed in 26 (40%). Male gender was significantly more frequent in CMD (P = 0.020), and mean age was significantly higher in IMD (P = 0.025). Body mass index and the American Society of Anesthesiologists score >2 were similar in both groups. Laparoscopy was carried out in 36% of IMD and in 50% of CMD patients (P = 0.309). A tangential resection was performed in 92% of IMD and 73% of CMD patients (P = 0.07). No complications related to diverticular resection were found in IMD, while they occurred in 8% of CMD patients (P = 0.931). Meanly, diverticula were longer when complicated (P = 0.001). CMD showed significant histological differences and more frequent gastric ectopic mucosa (P = 0.039). A malignant tumour was incidentally found in IMD. Conclusion: As surgery is mandatory in CMD, the optimal management of IMD remains uncertain. Mucosal abnormalities may favour complications, but these cannot be identified before excision. Stapled diverticulectomy is safe and effective. A surgical approach to IMD may prevent complications at a very low cost.

Abstract

Background: The aim of this study was to assess the indication for surgical treatment of incidentally discovered Meckel's diverticulum (MD) on the basis of clinical and histological features. Methods: The charts of patients undergoing surgery for MD were analysed. Two groups were identified: (1) patients who had incidentally discovered MD resected (incidental MD, IMD) and (2) patients who received first-line surgery for a complicated MD (CMD). Demographics and intraoperative and post-operative outcomes were compared. Histological findings were also analysed and compared. Results: Sixty-five patients were included in the study. IMD was observed in 39 patients (60%), while CMD was observed in 26 (40%). Male gender was significantly more frequent in CMD (P = 0.020), and mean age was significantly higher in IMD (P = 0.025). Body mass index and the American Society of Anesthesiologists score >2 were similar in both groups. Laparoscopy was carried out in 36% of IMD and in 50% of CMD patients (P = 0.309). A tangential resection was performed in 92% of IMD and 73% of CMD patients (P = 0.07). No complications related to diverticular resection were found in IMD, while they occurred in 8% of CMD patients (P = 0.931). Meanly, diverticula were longer when complicated (P = 0.001). CMD showed significant histological differences and more frequent gastric ectopic mucosa (P = 0.039). A malignant tumour was incidentally found in IMD. Conclusion: As surgery is mandatory in CMD, the optimal management of IMD remains uncertain. Mucosal abnormalities may favour complications, but these cannot be identified before excision. Stapled diverticulectomy is safe and effective. A surgical approach to IMD may prevent complications at a very low cost.
