Signs and tests Return to top
Examination of the abdomen typically shows tenderness. The abdomen may feel firm and "board-like" and there may be extensive "guarding" (protective movements such as curling up or refusal to allow the abdomen to be touched).
Blood tests and x-rays or CT scans may be ordered.
Treatment Return to top
The cause must be identified and treated promptly.
Treatment typically involves surgery and antibiotics. In cases associated with peritoneal dialysis, antibiotics may be infused through the dialysis catheter, but if the infection is severe, the catheter itself must often be removed.
