Review Case ReportsAsymptomatic pneumoperitoneum diagnostic and therapeutic dilemma.
The most common cause of pneumoperitoneum is iatrogenic postsurgical free air that enters the abdominal cavity during laparotomy. In these patients, pneumoperitoneum usually resolves within the first week of surgery and laparoscopic procedures. In patients who have not had recent laparotomy or laparoscopy, pneumoperitoneum indicates rupture of an intra-abdominal viscus in about 90 per cent of the time. ⋯ We report here six patients who presented to Howard University Hospital with nonsurgical pneumoperitoneum. Four of these patients underwent negative laparotomies and one died postoperatively. The most common causes of benign pneumoperitoneum are discussed and a review of the literature is presented.
