Case series of non-ampullary duodenal adenomas.

Duodenal adenomas are benign tumours of the duodenum which carry a malignant potential. They are found either sporadically or associated with familial syndromes. Majority of these cases are treated endoscopically but surgical resection is a better alternate to endoscopy in select cases. Endoscopic treatment is associated with higher chances of local recurrence and require frequent check endoscopies in the follow up period, while surgery offers a one-time treatment option. Identification of the ampulla and a duodenal resection sparing ampullary area becomes difficult in larger lesions of the 2nd part of the duodenum. Passage of a catheter from cystic duct through common bile duct to duodenum aids in identification of the ampullary area and is helpful in performing a local/wedge resection of the duodenum containing adenoma without injuring ampullary orifice.
