Ampullary composite gangliocytoma/neuroma and neuroendocrine tumor (CoGNET), previously called ampullary gangliocytic paragangliomas, is a rare entity, with only few reported cases in the literature. This is a multicentric retrospective cohort study of patients treated with endoscopy or surgery for ampullary CoGNET. A literature review of ampullary CoGNET was also performed.

Vermiform appendiceal cancers are rare and commonly diagnosed incidentally after appendectomy for acute appendicitis. Establishing a diagnosis and staging appendiceal cancer is important as the treatment options differ based on the subtypes of tumor and their spread in the peritoneum. The role of endosonography in tissue diagnosis of appendiceal cancer is limited.

Surgical resection for ampullary lesions lacks clear guidelines. Pancreaticoduodenectomy (PD) is the standard treatment for malignant ampullary tumors but is often excessive for ampullary adenomas (AAs) due to its high morbidity and mortality. Transduodenal ampullectomy (TDA) is generally reserved for small benign lesions where endoscopic treatment fails, but its role in early ampullary cancers is debatable.

Objective: Ampullary neoplastic lesions can be resected by endoscopic papillectomy (EP) or transduodenal surgical ampullectomy (TSA) while pancreaticoduodenectomy is reserved for more advanced lesions. We present the largest retrospective comparative study analysing EP and TSA.
Design: Of all patients in the database, lesions with prior interventions, benign histology advanced malignancy (T2 and more), patients with hereditary syndromes and those undergoing pancreatoduodenectomy were excluded.
