Idiopathic Spontaneous Pneumoperitoneum and Call for a Multi-Institutional Database.

Idiopathic spontaneous pneumoperitoneum (ISP) refers to intraperitoneal air of unknown origin when other more common etiologies such as traumatic, intrathoracic, and gynecologic etiologies have been excluded. We present a case of a 42-year-old woman with insignificant history presenting with ISP who underwent exploratory laparoscopy and thorough diagnostic workup that was ultimately unrevealing. This case report adds to the existing literature of ISP, and the authors recommend initiating a multi-institutional database to improve our understanding of ISP and contribute to developing consensus guidelines for presumed ISP.
