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.
Background: Dorsomedian nasopharyngeal masses with benign macroscopic appearance are frequently observed during retrograde nasopharyngoscopy, particularly in brachycephalic breeds, but are not well described.
Hypothesis/objectives: To characterize these masses, assess their frequency, and identify the potential factors associated with their presence.
Animals: Dogs that underwent retrograde nasopharyngoscopy at a private hospital.
