title: Large Tubullo-villous Adenoma of Duodenum Presenting as Gastric Outlet Obstruction.
abstract: Tubullo-villous adenoma of duodenum is a rare entity. These are potentially malignant tumours and therefore, complete excision is the treatment of choice. However, at times preoperative diagnosis could not be always achieved posing difficulty in choosing the optimal surgical method of excision. We report a 40-year-old male patient presented with vague upper abdominal pain and vomiting for last 6 months. His computed tomography and endoscopy demonstrated intraluminal polypoidal mass. Endoscopic biopsies were negative for malignancy. Local surgical excision with tumour free margin was performed and histology revealed tubullo-villous adenoma.
