Pneumoperitoneum after rough sexual intercourse.

Our objective is to report on a case of nonsurgical pneumoperitoneum and review the mechanism/gynecologic causes of such. We present a case report and review of the literature based on a MEDLINE search using the keywords pneumoperitoneum and nonsurgical. Radiographic evidence of free intraperitoneal air suggests hollow viscus rupture and usually warrants urgent surgical management. Findings of diffuse rebound tenderness and guarding solidify the decision for urgent surgical exploration. We present a case of a patient who presented with all of the above findings that subsequently underwent a negative laparotomy. On the day after surgery she admitted to having had rough sexual intercourse 3 days before presentation. Nonsurgical pneumoperitoneum has a number of unusual causes. Intra-abdominal, thoracic, gynecologic, iatrogenic, and miscellaneous etiologies are encountered. It was determined that the pneumoperitoneum in this case was secondary to rough sexual intercourse. We concluded that pneumoperitoneum secondary to nonsurgical causes represents a diagnostic dilemma. In the patient with free intraperitoneal air on plain X-ray one should be suspicious of less common nonsurgical etiologies. The majority of patients will require laparotomy. Thorough sexual and gynecologic/obstetrical history is a valuable adjunct in identifying the patient who does not.
