Transduodenal ampullectomy (TDA) is not in wide clinical use due to its low radical effect and a high recurrence rate of tumors. However, TDA is still an effective treatment method that has great clinical value in cases of duodenal benign tumors, precancerous lesions, and benign and malignant borderline tumors; it can avoid the risks associated with pancreaticoduodenectomy (PD) and offers a larger resection range and greater thoroughness than endoscopic papillectomy (EP).
The investigation of surgical method choice and the coincidence rate of pathological diagnoses in TDA can improve our understanding of TDA. TDA is still an effective treatment method and is of great clinical value in cases of duodenal benign tumors, precancerous lesions, and benign and malignant borderline tumors.
The main objective of this study was to investigate surgical method choice and the coincidence rate of pathological diagnoses in TDA.
Ten patients with ampullary neoplasm underwent TDA based on the fact that the endoscopic biopsy results suggested benign lesions and the endoscopic ultrasound (EUS)-assessed tumors were resectable. All cases underwent duodenal ampullary lesion endoscopic biopsy, intraoperative frozen-section pathology, and postoperative pathological examination.
There were seven patients with benign tumors and three with malignant tumors (1 pTis, 2 pT1) according to the postoperative pathology results. The coincidence rate of the postoperative pathology results with the intraoperative frozen-section biopsy results was 100% (10/10), and the coincidence rate with the endoscopic biopsy results based on pathological characteristics was 70% (7/10). The false-negative rate of endoscopic biopsy results was 30% (3/10). All patients were followed for 6 to 70 months without tumor recurrence or metastasis.
The coincidence rate of postoperative pathology results, intraoperative frozen-section pathology results, and endoscopic biopsy results is the restraining factor of TDA clinical application. Endoscopic biopsy results and EUS are an importance reference for surgical planning. Intraoperative frozen-section pathology results have a significant influence on the surgical procedure.
Due to the small sample size and the retrospective nature of the study, it is difficult to draw reliable conclusions. However, TDA is still an effective treatment method that has great clinical value in cases involving duodenal benign tumors, precancerous lesions, and benign and malignant borderline tumors. Based on the coincidence rate of postoperative pathology results, intraoperative frozen-section pathology results, and endoscopic biopsy results, TDA can be considered as a treatment choice between EP and radical PD.
