Summary
Endoscopic submucosal dissection (ESD) effectively diagnoses and treats non-ampullary duodenal tumors, including early-stage cancers. This minimally invasive technique offers a potential cure for duodenal carcinoma with no recurrence observed in this study.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Endoscopic Procedures
Background:
- Primary duodenal tumors are increasingly detected due to improved endoscopic technology.
- Accurate histological diagnosis can be challenging with endoscopic biopsies alone.
Observation:
- Four patients with non-ampullary duodenal tumors underwent endoscopic submucosal dissection (ESD).
- Tumors varied in size (10-31 mm) and included adenocarcinomas and adenomas with severe atypia.
- Two cases experienced perforation, managed conservatively with antibiotics and supportive care.
Findings:
- ESD enabled complete en bloc resection of all four duodenal tumors.
- No tumor recurrence was observed during an 18-month follow-up period.
- Histological confirmation of malignancy or pre-malignancy was achieved for all lesions.
Implications:
- ESD is a valuable tool for diagnosing and minimally invasively treating duodenal tumors, especially those with suspected malignancy.
- This technique provides a curative option for duodenal carcinoma without extensive surgery.
- ESD facilitates definitive histological diagnosis when biopsies are inconclusive.
