Prophylaxis against Postoperative Complications in Gastroenterology

Abstract

Gastrointestinal surgery results in pain, profound endocrine metabolic changes and organ dysfunction, immunosuppression and decreased resistance to infection, fatigue and convalescence. The main pathogenetic mechanism is the surgical stress response, which may be reduced by minimal invasive (laparoscopic) surgical techniques and afferent neural and perhaps humoral mediator blockade. Subsequently, these techniques have been documented as reducing a variety of postoperative morbidity parameters. A unifying concept for control of the postoperative period is presented as a combined effort to enhance preoperative information, stress reduction and sufficient functional pain relief allowing early mobilization and oral nutrition. Preliminary data, in combination with laparoscopic surgery, suggest that this approach improves outcome significantly.
