Gut access in critically ill and injured patients: Where have we gone thus far?

The Role of Nutritional Access in Malnourished Elderly Undergoing Major Surgery for Acute Abdomen: A Propensity Score-Matched Analysis

BACKGROUND

About 50% of the elderly undergoing emergency abdominal surgery are malnourished. The role of timely surgical nutritional access in this group of patients is unknown.

METHODS

We analyzed the National Inpatient Sample database from 2009 through the first three-quarters of 2015 of patients aged ≥65 years who were malnourished and underwent major abdominal surgery for the acute abdomen within the first 2 days of hospital admission.

RESULTS

Of 3 246 721 patients analyzed, 4311 patients met inclusion criteria. Of these, only 507 (11.8%) patients had surgical nutritional access (gastrostomy or jejunostomy) (group I), while 3804 patients (88.2%) did not (group II). In the propensity score-matched population, there were 482 patients in each group. The patients in group I had lower odds of mortality and postoperative gastrointestinal complications (paralytic ileus, anastomotic dehiscence, and intestinal fistulae) (P-value <.01, respectively).

DISCUSSION

Elderly who receive surgical nutritional access have lower rates of gastrointestinal complications and mortality.

Gastrointestinal tract access for enteral nutrition in critically ill and trauma patients: indications, techniques, and complications

BACKGROUND

Enteral nutrition (EN) is a widely used, standard-of-care technique for nutrition support in critically ill and trauma patients.

OBJECTIVE

To review the current techniques of gastrointestinal tract access for EN.

METHODS

For this traditional narrative review, we accessed English-language articles and abstracts published from January 1988 through October 2012, using three research engines (MEDLINE, Scopus, and EMBASE) and the following key terms: "enteral nutrition," "critically ill," and "gut access." We excluded outdated abstracts.

RESULTS

For our nearly 25-year search period, 44 articles matched all three terms. The most common gut access techniques included nasoenteric tube placement (nasogastric, nasoduodenal, or nasojejunal), as well as a percutaneous endoscopic gastrostomy (PEG). Other open or laparoscopic techniques, such as a jejunostomy or a gastrojejunostomy, were also used. Early EN continues to be preferred whenever feasible. In addition, evidence is mounting that EN during the early phase of critical illness or trauma trophic feeding has an outcome comparable to that of full-strength formulas. Most patients tolerate EN through the stomach, so postpyloric tube feeding is not needed initially.

CONCLUSION

In critically ill and trauma patients, early EN through the stomach should be instituted whenever feasible. Other approaches can be used according to patient needs, available expertise, and institutional guidelines. More research is needed in order to ensure the safe use of surgical tubes in the open abdomen.
