If properly treated, typical cases of surgically correctable peritonitis (e.g., perforated peptic ulcer, appendicitis, and diverticulitis) have a mortality rate of about <10% in otherwise healthy people. The mortality rate rises to 35% in peritonitis patients who develop sepsis, and patients who have underlying renal insufficiency and complications have a higher mortality rate.
