Cornell University Program of Computer Graphics The term computer graphics includes almost everything on computers that is not text or sound. Today almost every computer can do some graphics, and people have even come to expect to control their computer through icons and pictures rather than just by typing.
Anal fistula. An anal fistula is a small channel that can develop between the end of the bowel and the skin near the anus. An anal fistula can cause bleeding and discharge when passing stools-and can be painful. An anal fistula can occur after surgery to drain an anal abscess. In some cases, an anal fistula causes persistent drainage. In other cases, where the outside of the channel opening closes, the result may be recurrent anal abscesses. The only cure for an anal fistula is surgery.
Gastrocutaneous fistula is an infrequent but serious surgical complication which has received little attention in the recent literature. The current report analyzes 13 patients with this complication. The fistula most commonly occurs in the fundic portion of the greater curvature of the stomach and is usually a result of unrecognized iatrogenic injury or associated with severe left upper quadrant inflammation and external drainage.
