Diagnosis and Surgical Treatment of Primary Appendiceal Tumor: a Report of 13 Cases / 中国医师杂志

ABSTRACT

Objective To study the clinical characteristics and treatment of primary appendicular tumor. Methods The clinical data of 13 patients with primary appendicular tumor treated in our hospital from 1979 to 1999 were retrospectively analyzed. Results The primary appendicular tumors included 4 cases of mucinous tumor, 5 cases of carcinoid, 3 cases of adenocarcinoma and 1 case of leiomyosarcoma. None was diagnosed correctly before operation. All 13 cases were treated by operation. Right hemicolectomy was performed in carcinoid, diameter of which was longer than 1cm, right hemicolectomy and regional lymphadenectomy were performed in adenocarcinoma, and the other five cases were only received appendectomy. The patients were in good general condition after operation. Conclusions Primary appendicular tumor lacked particular symptoms, and the rate of misdiagnosis was extremely high. Barium radiography and ultrasonography were helpful for diagnosis. Intraoperative frozen section detection was very important for diagnosis. Operation is a principle therapy, and suitable operation plan may be key factor for improving the prognosis of the patients with appendicular tumor.
