Comparisons of nutritional status and complications between patients with and without postoperative feeding jejunostomy tube in gastric cancer: a retrospective study.

Background: Feeding jejunostomy tube (FJT) enables early postoperative nutritional supply for gastric cancer patients undergoing surgery. However, the nutritional benefit of FJT may be accompanied by potential risk of increased complications, so both the nutritional improvement and the complication rates associated with FJT should be assessed. Methods: From January 2009 to December 2014, 715 consecutive patients underwent gastric cancer resection at the Peking Union Medical College Hospital in China. The perioperative nutritional index and incidence of complications in patients with FJT placement were retrospectively compared to those in patients without FJT placement. Nutritional data including albumin, prealbumin, hemoglobin, and high sensitivity C-reactive protein, the neutrophil-to-lymphocyte ratio (NLR), and Onodera's prognostic nutrition index (OPNI) were recorded at the following 3 timepoints: preoperatively, 1-week postoperatively, and 1-month postoperatively. Postoperative complications including surgical site infection, intra-abdominal infections, anastomotic leaks and gastroparesis were assessed. Multivariate logistic regression was used to study the association between FJT and complications. Results: A total of 715 patients were included in the study. The mean age was 60.4 years and 72.2% were male. The overall characteristics between FJT and no-FJT groups were comparable. Of the 247 total gastrectomy cases, 98 (39.7%) had a FJT placed. Compared to the total gastrectomy patients without a FJT, the 98 patients with a FJT had a lower hemoglobin level (P=0.048) and NLR (P=0.030) preoperatively, and higher albumin (P=0.005), prealbumin (P<0.001), and hemoglobin (P=0.014) levels, a higher OPNI (P=0.027), and a lower NLR (P=0.005) 1-month postoperatively. Of the 468 subtotal gastrectomy cases, 87 (18.6%) had a FJT placed. Compared to the subtotal gastrectomy patients without a FJT, these 87 patients had a lower NLR (P=0.006) 1-week postoperatively, and a higher albumin level (P=0.009) 1-month postoperatively. In the multivariate analysis, FJT placement was not associated with postoperative adverse outcomes, including surgical site infection [odds ratio (OR) =1.21, P=0.79], intra-abdominal infection (OR =0.38, P=0.11), anastomotic leak (OR =0.58, P=0.53), reoperation (OR =0.22, P=0.23), gastroparesis (OR =6.35, P=0.08), or hospitalization for more than 30 days (OR =0.58, P=0.32). Conclusions: Early enteral nutritional support by FJT after gastrectomy tended to improve the nutritional status of patients, while it did not appear to increase the incidence rate of postoperative complications.
