1. Of, relating to, or affecting the peritoneum.
   • 1914, Transactions of the Section on Genito-Urinary Diseases of the American Medical Association, page 80:

Usage notes

• Peritoneal (which concerns certain organs or matter inside the abdomen) is not to be confused with peroneal (which concerns the lower leg) or perineal (which concerns the skin between the genitals and anus); the words can sound somewhat similar, especially in rapid speech such as during a doctor's dictation.
