The clinical impact of malnutrition on the postoperative outcomes of patients undergoing gastrectomy for gastric cancer: Propensity score matched analysis of 2011-2017 hospital database.

Background & Aims: Malnutrition is a prominent feature of gastric cancer patients who suffer from gastric outlet obstruction, impaired peristalsis, and cancer-mediated disruptions in metabolic hemostasis. In this study, we systematically evaluate the impact of malnutrition on the postoperative outcome of patients with gastric cancer undergoing gastrectomy.

Methods: 2011-2017 National Inpatient Sample was used to isolate patients with gastric cancer who underwent gastrectomy, who were stratified using malnutrition.

The clinical impact of malnutrition on the postoperative outcomes of patients undergoing colorectal resection surgery for colon or rectal cancer: Propensity score matched analysis of 2011-2017 US hospitals.

Background & Aims: Malnutrition can be prevalently found in patients with significant-to-advanced colorectal cancer, who potential require colorectal resection procedures; to accurately describe the postoperative risks, we used a propensity-score matched comparison of national database to analyze the effects of malnutrition on post-colectomy outcomes.

Methods: 2011-2017 National inpatient Sample was used to isolate inpatient ceases of colorectal resection procedures, which were stratified using malnutrition into malnutrition-present cohort and malnutrition-absent controls; the controls were propensity-score matched with the study cohort using 1:1 ratio and compared to the following endpoints: mortality, length of stay, costs, postoperative complications.

Results: After matching, there were 11357 with and without malnutrition who underwent colorectal resection surgery; in comparison, malnourished patients had higher rates of in-hospital mortality (6.

The clinical impact of cirrhosis on the postoperative outcomes of patients undergoing bariatric surgery: propensity score-matched analysis of 2011-2017 US hospitals.

: Since there is increasing number of patients with cirrhosis who require the bariatric procedure due to obesity and obesity-related nonalcoholic steatohepatitis fibrosis, we evaluate the effect of cirrhosis on post-bariatric surgery outcomes.: 2011-2017 National Inpatient Sample was used to isolate bariatric cases, which were stratified by cirrhosis; controls were propensity-score matched to cases and compared to endpoints: mortality, length of stay (LOS), costs, and postoperative complications.: From 190,753 patients undergoing bariatric surgery, there were 957 with cirrhosis and 957 matched controls.
