[Barium meal after pancreatic surgery (author's transl)].

After duodenopancreatectomy the roentgenpattern of the upper gastrointestinal tract resembles the pattern after Billroth I- or Billroth II- resection. A different aspect results after Y-Roux anastomosis. The follow-up of pseudocysts drained into the stomach poses no problems. The follow-up of pseudocysts drained into the small bowel demands a roentgenexamination with duodenal intubation. The use of hypotonia is advisable in the diagnosis of malignancy. Problems may arise in roentgendiagnostics after palliative operations.
