BACKGROUND: Preexisting malnutrition has been shown to be a major clinical problem in surgical patients. Surgical stress itself increases the energy expenditure and protein loss making necessary the early nutritional support. Although there is strong evidence that "nil by mouth" is not justified, the data are still conflicting over the role of early enteral nutrition compared with the traditional methods of postoperative feeding including total parenteral nutrition support. METHODS AND FOCUS: This paper deals with the various trials related to early enteral feeding. It also compares this with the possible advantages of total parenteral nutrition as a method of perioperative nutritional support in patients undergoing gastrointestinal surgery.

Malnutrition is a common and significant problem in patients with cancer. Enteral nutrition support is an important therapy and is preferred over parenteral nutrition in the setting of a functional gastrointestinal tract. Familiarity with the indications for enteral support, the choice of an enteral access device, and the selection of an enteral formula are critical for the care of patients with cancer and malnutrition. Enteral nutrition has proven efficacy in patients receiving radiation to the head and neck, those with persistent dysphagia, and critically ill patients with impaired gastric emptying. Placement of feeding tubes through the nose or percutaneously provides a mechanism to deliver nutrients when proximal obstructions or oropharyngeal dysphagia prevent adequate oral intake. Direct access to the jejunum can be safely obtained endoscopically and is very useful in patients who require enteral nutrition support following a gastrectomy or esophagectomy or have impaired gastric emptying. Standard polymeric formulas are appropriate for most patients. Specialized formulas designed to enhance immune function may decrease infectious complications but do not improve survival.
