The key step in Meckel's diverticulectomy (MD) is to achieve complete resection of MD along with the ectopic epithelium. Currently main treatment methods for Meckel's diverticulum are either intestinal resection and anastomosis or wedge resection. Here we introduced a new method to treat MD. The goal of this study was to investigate the clinical effects and advantages of a new operation method for Meckel's diverticulum: basal ligation combined with intraoperative frozen section. 262 cases of Meckel's diverticulum were resected with simple basal ligation operation. Intraoperative frozen pathological section was performed to determine surgery strategies. Based on the existence of basal residual ectopic mucosa, surgery was either terminated or further wedge intestinal resection or bowel resection was performed. All 262 surgeries were successfully completed. Additional wedge resection or bowel resection was performed in only 23 of them due to the presence of ectopic basal residual gastric mucosa. No ectopic mucosa was found for the other cases, and the operation ended after basal ligation. All patients had no complications such as intestinal fistula, bleeding for 6 months-7.6 years after surgery. Intraoperative frozen pathological examination can well determine whether ectopic Meckel's diverticulum mucosa locates at the basal part. Basal ligation is a safe and effective operation method, and it can significantly shorten the operation time and postoperative fasting time.
