[The aberrant pancreas in gastro-duodenal disease. A clinical, endoscopic-bioptic study].

30 instances of aberrant pancreas were noted in 13,620 routine gastroduodenoscopies (0.22%), usually in the antrum or duodenum (antrum 83.5%, cap 6.6%, D2 6.6%). Symptoms, where present, took many forms and were aspecific, since they were related to size and site. The difficulties surrounding conventional methods of diagnosis are explained. Radiology reveals local alteration in 80% of cases, though its offers formally useful data in only 10%. Endoscopy and oriented biopsy partly make up for this inadequancy, because an aberrant pancreas may present as an atypical, nonumbelicated form that cannot be endoscopically distinguished from other benign growths. In addition, biopsy of the pancreas may be difficult in a submucosal site. Given the relative inefficacy of even the most recent techniques, perendoscopic polypectomy is proposed as a means of combining optimum diagnosis and radical treatment.
