Summary
Duodenal villous tumors are rare and can become malignant. Early diagnosis with hypotonic duodenography and fibroscopy, along with intraoperative frozen section analysis, is crucial for effective treatment and preventing recurrence.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Context:
- Duodenal villous tumors are uncommon neoplasms.
- This study reviews 8 cases of duodenal villous tumors, totaling 11 excised lesions.
- Tumors were located in the duodenal bulb (2) and descending part (9).
Purpose:
- To analyze the characteristics, diagnosis, and management of duodenal villous tumors.
- To highlight the importance of intraoperative frozen section examination.
- To emphasize the need for long-term postoperative follow-up.
Summary:
- Malignant transformation was observed in 50% of the cases (4 out of 8 patients).
- Diagnosis can be achieved through hypotonic duodenography and upper gastrointestinal endoscopy (fibroscopy).
- Intraoperative frozen section analysis is recommended to guide surgical decisions and ensure complete tumor removal.
Impact:
- Accurate diagnosis and appropriate surgical intervention are key to successful outcomes.
- Periodic postoperative surveillance is necessary due to the risk of tumor recurrence after local excision.
- This case series contributes to understanding the clinical behavior and management strategies for duodenal villous tumors.
