OBJECTIVES:Limited information is available concerning the post-treatment neutrophil-lymphocyte ratio in critical limb ischemia patients who receive conservative therapy. Accordingly, this study was designed to evaluate the predictive value of the post-treatment neutrophil-lymphocyte ratio in critical limb ischemia patients without surgery.METHOD:From January 2009 to January 2011, critical limb ischemia patients were admitted to a vascular center. The demographic data, patient histories, comorbidities and risk factors were documented, and the differential cell count was determined at admission and seven days later after conservative therapy. The cutoff value of the post-treatment neutrophil-lymphocyte ratio was determined by an ROC curve. Patients were divided into groups A and B according to the cutoff value. Amputation-free survival was compared between groups. Univariate and multivariate analyses were used to identify independent risk factors.RESULT:A total of 172 patients were identified with a mean age 71.98±10.09 years; among them, 122 were male. A value of 3.8 was identified as the cutoff value of the post-treatment neutrophil-lymphocyte ratio. Groups A (post-treatment neutrophil-lymphocyte ratio ≥3.8) and B (post-treatment neutrophil-lymphocyte ratio <3.8) showed a significant difference in amputation-free survival (P<0.001). The 1-year, 2-year and 3-year amputation-free survival rates were 79.6%, 55.6% and 46.3%, respectively, in group A; however, in group B, these values were 89.7%, 79.3% and 75.9%, respectively. The post-treatment neutrophil-lymphocyte ratio was identified as an independent predictive factor for amputation in critical limb ischemia patients (P<0.001).CONCLUSION:The post-treatment neutrophil-lymphocyte ratio is an independent predictive factor for amputation in critical limb ischemia patients. Patients with a post-treatment neutrophil-lymphocyte ratio ≥3.8 are likely to suffer from amputation; amputation-free survival usually occurs in patients with a post-treatment neutrophil-lymphocyte ratio <3.8.

BackgroundChylous ascites is the pathologic leakage of triglycerides-rich lymphatic fluid into the peritoneal cavity. Chylous ascites is a rare complication in abdominal surgery. This study aimed to find a relatively better method for nutrition support in the treatment of chylous ascites after abdominal surgery.MethodsThis study was a retrospective study. This study retrospectively reviewed patients who underwent abdominal surgery and developed chylous ascites, from the year 2010 to 2014, at the West China Hospital of Sichuan University and the Affiliated Hospital of Zunyi Medical College. Fifty-eight patients who developed chylous ascites after abdominal surgery were included in the study. The clinical effect of somatostatin was evaluated. The differences in the curative efficacy among a daily diet, a low-fat diet supplemented with medium-chain triglyceride (MCT), and total parenteral nutrition (TPN) were also analyzed in this study.ResultsComplete clinical success was reached earlier in patients treated with somatostatin (P<0.001). The tube removal time, the time to resumption of an oral diet, and the length of hospital stay after chylous leakage were significantly different between patients treated with and without somatostatin. The curative efficacies of the enteral nutrition (EN) + MCT plan and the TPN plan were quite similar, with no significant difference, however, were significantly different from the MCT regime, which was the worst. However, using the EN + MCT plan was more cost-effective (P=0.038).ConclusionIn treating chylous ascites, EN + MCT instead of TPN was the best nutrition support. Moreover, somatostatin or its analog octreotide should be used immediately. The treatment with somatostatin in combination with EN + MCT is recommended in the conservative treatment of postoperative chylous ascites.
