Objective:To compare the therapeutic characteristics of anterior hybrid decompression and posterior cervical posterior laminectomy in the treatment of multilevel cervical spondylotic myelopathy.Methods:Thirty six cases of multilevel cervical spondylotic myelopathy patients treated by anterior hybrid decompression and thirty three cases of multilevel cervical spondylotic myelopathy patients treated by posterior cervical posterior laminectomy were involved.The general information,bleeding amount,operative time,cervical curvature D value,JOA score and incidence of postoperative complications of the two groups before and after surgery were compared.Results:There was no significant difference in the general information among the two groups(P＞0.05),including age (anterior group:56.23± 7.64 years old,posterior group:55.76± 8.18 years old),sex (anterior group:22 males/14 females,posterior group:20 males/13 females),cervical curvature D value (anterior group:7.41± 3.14,posterior group:8.19± 2.74),JOA score (anterior group:9.08± 1.09 scores,posterior group:8.82± 1.26 scores),disease course (anterior group:17.24± 7.36 months,posterior group:15.75± 5.78 months) and affected segment (anterior group:3.11 ± 0.26 segments,posterior group:3.24± 0.39 segments).The the amount of bleeding in the anterior group (anterior approach:221.79± 178.02 ml,posterior group:483.07± 434.25 ml) was lower than that of the posterior group(P＜0.05).The operative time (anterior group:196.54± 51.88 mins,posterior group:175.12± 54.93 mins) was longer,but there was no significant difference (P＞0.05).The cervical curvature D value and JOA score of posterior group were increased with the extension of surgery time.However,the cervical curvature D value of posterior group was decreased,but JOA score was increased.The incidence of bone unfinished,hoarseness and cerebrospinal fluid leakage were found in the anterior group,and axial pain and C5 nerve root paralysis were found in the posterior group.But there was no significant difference in the incidence of complications between the two groups (anterior group 14.89％,posterior group:12.12％)(P＞0.05).Conclusions:Anterior hybrid decompression and posterior cervical posterior laminectomy had their own advantages in the treatment of multilevel cervical spondylotic myelopathy.,The appropriate treatment should be taken according to the condition of patients.

Objective To review our experiences in portaazygous disconnection for the treatment of portal hypertension and to analyze the causes of postoperative complications. Methods We reviewed the results of 236 patients with portal hypertension who were treated with disconnection from April 1994 to July 2002. Results Postoperative complications occurred in 65 of all the patients(the incidence rate was 27.5%). Twenty-four patients experienced postoperative infection(10.2%),12 patients suffered from intraabdominal massive bleeding(5.1%),12 from massive ascites (5.1%),8 patients suffered from recurrent upper gastrointestinal bleeding (3.4%),7 patients experienced acute thrombosis of portal venous system(3.0%). Two patients suffered from multiple organ dysfunction syndrome (1.0%). The operative mortality was 3.4%(8/236). The main causes of death included intraabdominal massive bleeding and severe infection with MODS. Conclusions The occurrence of postoperative complications was related with the selection of patients,thorough portaazygous disconnection and perioperative management.

ObjectiveTo learn the clinical characteristics of concurrent acute-on-chronic liver failure (ACLF) and hepatorenal syndrome (HRS), and to investigate the predictive factors for HRS in patients with ACLF. MethodsA total of 806 patients with ACLF who were admitted to our hospital from January 2012 to May 2014 were selected and divided into two groups according to the incidence of concurrent HRS. Clinical indices and laboratory test results were analyzed in the two groups, and the multivariate logistic regression analysis was used to figure out independent indices for the prediction of HRS in patients with ACLF. A prediction model was established and the receiver operating characteristic curve was drawn to evaluate the accuracy of the prediction model. Comparison of continuous data between the two groups was made by t test, and comparison of categorical data between the two groups was made by χ2 test. ResultsIn all patients with ACLF, 229 had HRS and 577 had no HRS. The univariate logistic regression analysis showed that hepatic encephalopathy, peritonitis, infection, age, cystatin C (Cys-C), serum creatinine (SCr), blood urea nitrogen, albumin, prealbumin, total bilirubin, direct bilirubin, total cholesterol, K+, Na+, phosphorus, Ca2+, prothrombin time, prothrombin activity, international normalized ratio, and hematocrit were significant predictive factors for HRS. The multivariate logistic regression analysis showed that concurrent peritonitis, Cys-C, SCr, and HCO3- were independent predictive factors for HRS in patients with ACLF (OR=3.155, P＜0.01; OR=30.773, P＜0.01; OR=1062, P＜0.01; OR=0.915, P＜0.05). The model was proved of great value in prediction. ConclusionConcurrent peritonitis, Cys-C, SCr, and HCO3- are effective predictive factors for HRS in patients with ACLF.
