Did you know?

This was an interesting story I heard yesterday, though not in quite as vivid a detail.
A 25 yo girl comes into ER with abdominal pain and vomiting though vomiting started after the pain. KUB shows free air. The girl is stable but she is tender. Attending is called in to take the girl to the OR to see if she perfed an ulcer or what. Right before going to the OR, the attending asks her if she had rough sex the night before (earning himself the looks of "say wha?") and anyway, any such activity is denied. The lap doesnt show any perforation, but there is some fluid in cul-de-sac which ob/gyn evaluates intra-op and says it looks physiological. Next day and (with her father this time in the room), the girl mentions that she may have had enough to drink the night before to not remember anything and or pass out and oh by the way she has a new partner. Apparently during rough sex, air can get pushed up into the uterus and out the fallopian tubes, causing intraperitoneal air with more or less irritating symptoms. Moral of the story: if you think the family is dysfunctional, get the family in the room to get the best sexual history ever.
