Well it was another interesting night on call. This was one of thoose rare times when the main teaching objective was when not to operate. We admitted a middle-age male with an attack of presumed diverticulitis. He had a CT scan that was not indicative of an acute free perforation, his abdominal exam showed mostly localized left lower quadrant tenderness, but no signs of peritoneal irritation. He was started on IV fluids and antibiotics and after 12 hours shows some improvement. He will continue to be observed for improvement or worsening. JTE.
