Laparoscopic omentectomy for omental infarction after bicycle handlebar injury.

Handlebar injuries in children are commonly associated with significant gastrointestinal and solid organ damage. In this paper, we report a rare case of an isolated omental injury in a 6-year-old child after a blunt trauma with a bicycle handlebar. We describe a successful laparoscopic omentectomy performed with the LigaSure Atlas.

History of mesenteric ischemia. The evolution of a diagnosis and management.

This article has traced the evolution of our knowledge of mesenteric ischemia from the initial stage of recognition of the condition and its manifestations, through the phase of treatment after the fact-resection of gangrenous intestine, to our present-day attempts to diagnose and treat the ischemic episode before death of the bowel and patient occurs. It is history from the authors' perspective, and because of limitations of space it is, perforce, highly selective. Hundreds of valuable contributions could not be included, and their omission in no way detracts from their importance.

Bloodless splenic surgery: the safe warm-ischemic time.

To assess the feasibility of a technique of bloodless splenic surgery, experiments were performed to determine the safe warm-ischemic time of the spleen. Ten mongrel dogs were divided into two groups. Group I (n = 5) underwent division of all collateral splenic vessels, followed by total splenic artery and vein occlusion for 3 hours.

Pathophysiology of mesenteric ischemia.

Intestinal ischemia can result from a host of pathophysiologic disturbances and, in turn, may produce a variety of adverse local and systemic consequences. Mechanisms of ischemic injury and the central role of vasoconstriction are discussed.
