Impact of preoperative hand grip strength on morbidity following XXXX surgery.

BACKGROUND: @entity6288 is a decrease in both muscle mass and strength. It remains unclear whether @entity6288 is associated with morbidity after @entity356 surgery. This study evaluated the impact of @entity6288 on the morbidity of @entity356 surgery. METHODS: A total of 293 @entity356 @entity1 who underwent curative surgery between May 2011 and June 2013 were retrospectively examined. @entity1 with performance status 3 or 4 were excluded. Preoperative lean body mass (LBM) was evaluated by bioelectrical impedance analysis and expressed as LBM index. Preoperative muscle function was measured by hand grip strength (HGS). The cutoff values were the gender-specific lowest 20  %. Grade 2 or higher morbidities, as retrospectively evaluated by the Clavien-Dindo classification, were obtained from the @entity1 record. The risk factors for morbidity were examined by univariate and multivariate analyses. RESULTS: Morbidity was observed in 39 @entity1 (13.3  %), including 7 with pancreatic leakage, 12 with @entity834 , and 4 with intraabdominal abscesses, but no mortality was observed. The univariate analysis showed that male gender, total gastrectomy, splenectomy, and a low HGS were significant risk factors for morbidity. A low LBM was not a significant risk factor. A low HGS, male gender, and total gastrectomy remained significant in the multivariate analysis. CONCLUSIONS: A low hand grip strength was a significant risk factor for morbidity after @entity356 surgery. The importance of the hand grip strength as a risk factor should be examined in future prospective studies.
