In medicine,<unk>  is pain presenting in the right lower quadrant of the abdomen caused by a duodenal ulcer with perforation through the retroperitoneum. It is named after Rudolph<unk> , an Italian actor, who presented with right lower quadrant pain in New York, which turned out to be a perforated peptic ulcer. He subsequently died from an infection and organ dysfunction in spite of surgery to repair the perforation. Due to his popularity, his case received much attention at the time and is still considered a rare medical condition. However, the degree of peritoneal findings is strongly influenced by a number of factors, including the size of perforation, amount of bacterial and gastric contents contaminating the abdominal cavity, time between perforation and presentation, and spontaneous sealing of perforation.
