Crohn's disease of the colon.

The surgical treatment of Crohn's disease of the colon is distinct from that used in treating ulcerative colitis. Crohn's disease often involves the small bowel and is not "cured" by colorectal resection. The popular ileo-anal pouch procedures used in the management of ulcerative colitis generally are not used for the treatment of Crohn's colitis, because of higher complication rates. Commonly performed operations include ileostomy, segmental colon resection, subtotal colectomy, and proctocolectomy. The general surgeon, therefore, is provided with many options when faced with complications of Crohn's colitis. This article examines the attributes of and results reported for each of these options.

Thoracoscopic diaphragmatic plication.

We report on thoracoscopic plication of the the paralyzed right hemidiaphragm of a 33-year-old woman with a history of reactive airway disease. The paralysis was secondary to transection of the phrenic nerve during right first rib resection for thoracic outlet syndrome 1 year prior to evaluation. By use of video-assisted thoracoscopic surgery (VATS), the diaphragm was plicated as with open thoracotomy. Postoperative recovery was uneventful, with minimal pain and early discharge. Preoperative symptoms of exertional dyspnea and orthopnea were significantly improved.

Evolution and current status of the total artificial heart: the search continues.

Artificial hearts have been used for temporary and permanent replacement of failing human hearts. Attempts at permanent implantation during the 1980s were complicated by a high incidence of infection and thromboembolism, combined with a low quality of life for recipients. Given the success of cardiac transplantation, the artificial heart was relegated to temporary use in critically ill patients who were waiting for a donor heart. Continued difficulties with complications, combined with the success of ventricular assist devices for this purpose, dramatically reduced the use of the artificial heart. However, the recent development of compact electromechanical artificial hearts powered by transcutaneous energy systems has led to renewed hope for the possibility of permanent implantation. Some of these devices have been successful in animal studies and are approaching human trials. After years of hope and disappointment, artificial heart technology may be on the verge of efficacy. The history, status, and future of the artificial heart are discussed.
