    Abstract:
    BACKGROUND: The association between sarcopenia and postoperative outcomes in patients who undergo laparoscopic-assisted gastrectomy is unclear. We aimed to determine the predictive value of sarcopenia for adverse postoperative outcomes after laparoscopic-assisted gastrectomy for gastric cancer. MATERIALS AND METHODS: We prospectively collected the clinical data of patients who underwent elective radical laparoscopic-assisted gastrectomy for gastric cancer in two large centers from August 2014 to October 2017. The third lumbar vertebra skeletal muscle index, handgrip strength, and 6-m usual gait speed were measured to diagnose sarcopenia. Subsequently, we aimed to identify the risk factors for postoperative complications. RESULTS: The study included 313 patients and 37 (11.8%) patients were classified as sarcopenic. Compared with non-sarcopenic patients, sarcopenic patients were significantly older (P < 0.001), had higher nutritional risk screening 2002 scores (P = 0.013), Charlson comorbidity index (CCI) scores (P = 0.033), and neutrophil to lymphocyte ratio (P = 0.004), and lower body mass index (P < 0.001), preoperative serum albumin (P < 0.001), and hemoglobin (P < 0.001). Sarcopenic patients had higher postoperative complication rate (P = 0.002), longer postoperative hospital stays (P = 0.020) and higher total cost of hospitalization (P = 0.001). Multivariate analysis revealed that CCI score ≥1 (odds ratio [OR]: 2.424, 95% confidence interval [CI]: 1.309-4.487; P = 0.005) and sarcopenia (OR: 2.752, 95% CI: 1.274-5.944; P = 0.010) were independent risk factors for short-term postoperative complications. CONCLUSION: Sarcopenia is an independent clinical predictor of short-term postoperative complications after laparoscopic-assisted gastrectomy.
