PERFORATED DUODENAL ULCER
Close, but not quite there.

The duodenal ulcer was the underlying cause of death in this patient; gastric contents escaped through into the peritoneal cavity via the perforation. However, the ulcer in itself didn't kill the patient; what would three litres of bacteria-laden intestinal contents do to the peritoneum assuming the ulcer wasn't picked up the moment it perforated?
