Diagnosis and treatment of primary malignant tumors of the duodenum:a report of 82 cases / 中国普通外科杂志

ABSTRACT

Objective To investigate the clinical manifestations, histopathological patterns, and methods of diagnosis and treatment of primary malignant duodenal tumors. Methods The data of 82 patients with primary malignant duodenal tumors confirmed by pathology and admitted to our hospital over a 10-year period were analyzed retrospectively. Results Tumor locationTumors were located in the peripapilla region in 64 cases, at the descending portion of the duodenum in 11 cases, at other regions of the duodenum in 7 cases. The common presenting symptoms and signs were abdominal pain in 57 cases, jaundice 53 cases, and gastrointestinal bleeding in 41 cases. In these patients, radical resection of tumor was performed in 36 cases, palliative resection of tumor in 31cases,and operative intervention was not done in 15 cases.The 5-year survival rate of followed-up patients in this group was 2.4%. Conclusions The common presenting symptoms and signs of patients with primary malignant duodenal tumors were abdominal pain, jaundice and GI bleeding, but these patients usually lack specific symptoms and signs. The chief pathologic type is adenocarcinoma and the predisposed site of occurrence is the duodenal papillary region and the descending duodenum . CT, B ultrasonography and gastroduodenoscopy are the chief measures for the diagnosis of primary duodenal malignant tumors, and surgical resection is the main modality of treatment of this disease. The prognosis of primary duodenal malignant tumors is very poor.
