Endoscopic Ampullectomy for Tumors of the Ampulla of Vater: Long-term Follow-up Results / 대한소화기내시경학회지

ABSTRACT

BACKGROUND/AIMS: The resectability rate and prognosis of tumors of the ampulla of Vater are significantly better than for other periampullary tumors. Treatment for ampullary tumors has traditionally been surgical resection. However, endoscopic ampullectomy has been reported in patients with benign ampullary tumors. This study is being conducted to evaluate the availability of endoscopic ampullectomy. METHODS: Between 1994 and 1996, 6 cases (M F=5 1) with ampullary tumors were treated by endoscopic ampullectomy. Clinical presentations, complications, pathologic findings, and follow-up information were reviewed. RESULTS: Complete resection was perfomed in 5 cases. Pancreatitis after this procedure occurred in 2 cases, but were resolved by conservative care. Pathologic findings of resected specimens were adenama in 4 cases and adenocarcinoma in 2 cases. There was no recurrence in adenoma during the follow-up period (9-37 months) except in one case, which the patient was lost after 9 months. In one case with adenocarcinoma, the patient refused the operation, and consequently had the tumor recurrence 13 months later. CONCLUSIONS: Endoscopic ampullectomy was considered safe and effective treatment for removing benign ampullary tumors as well as malignant tumors, the latter of which are not considered suitable for operation.
