Objective:To investigate the influencing factors for anastomotic biliary stric-ture after liver transplantation.Methods:The retrospective case-control study was conducted. The clinical data of 428 recipients who underwent allogeneic orthotopic liver transplantation in the First Hospital of Jilin University from September 2014 to August 2021 were collected. There were 324 males and 104 females, aged (52±10)years. Observation indicators: (1) surgical conditions of recipients; (2) occurrence of anastomotic biliary stricture after liver transplantation and its treat-ment; (3) analysis of influencing factors for anastomotic biliary stricture after liver transplantation. Follow-up was conducted using outpatient examination to detect occurrence of anastomotic biliary stricture and treatment up to August 30, 2021. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measure-ment data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were represented as absolute numbers, and the chi-square test was used for comparison between groups. Logistic regression model was used for multivariate analysis. Results:(1) Surgical conditions of recipients: the operation time of 428 recipients was 465(420,520)minutes, the cold ischemia time was 368(320,450)minutes, and the volume of intraoperative blood loss was 2 500(1 500,4 000)mL. Of the 428 recipients, 142 cases were performed continuous biliary posterior wall anastomosis + interrup-ted anterior wall anastomosis by polygluconate sutures, 286 cases were anastomosed with polypro-pylene sutures, including 169 cases undergoing continuous biliary posterior wall anastomosis combined with interrupted anterior wall anastomosis, 73 cases undergoing completely interrupted biliary anterior and posterior wall anastomosis, and 44 cases undergoing completely continuous biliary anterior and posterior wall anastomosis. None of the 428 recipients had indwelling T tubes. (2) Occurrence of anastomotic biliary stricture after liver transplantation and its treatment:all the 428 recipients were followed up for 3 to 72 months, with a median follow-up time of 28 months. During the follow-up, 50 patients developed anastomotic biliary stricture, of which 41 patients were treated with endoscopic retrograde cholangiopancreatography, 8 patients were treated with percutaneous transhepatic cholangial drainage, and 1 patient was treated with surgery, showing no recurrence. (3)Analysis of influencing factors for anastomotic biliary stricture after liver transplanta-tion: results of univariate analysis showed that anastomosis method and donor liver cold ischemia time were related factors for postoperative anastomotic biliary stricture of recipients undergoing allogeneic orthotopic liver transplantation ( χ2=15.74, Z=-2.04, P<0.05). Results of multivariate analysis showed that completely interrupted biliary anterior and posterior wall anastomosis and donor liver cold ischemia time were independent influencing factors for postoperative anastomotic biliary stricture of recipients undergoing allogeneic orthotopic liver transplantation ( odds ratio=0.25, 1.00, 95% confidence interval as 0.08-0.85, 1.00-1.01, P<0.05). Conclusions:Suture type is not an influencing factor for postoperative anastomotic biliary stricture of recipients undergoing allogeneic orthotopic liver transplantation. Completely interrupted biliary anterior and posterior wall anastomosis and donor liver cold ischemia time were independent influencing factors.

Objective To study the effects of perioperative body temperature management on intraperitoneal hyperthermic perfusion chemotherapy patients with abdominal malignant tumor. Methods From June to Decmber 2016, a total of 120 intraperitoneal hyperthermic perfusion chemotherapy patients with abdominal malignant tumor who met the inclusion criteria were recruited and randomly divided into control group and observation group, with 60 cases in each. All the subjects were given routine operation nursing. On the basis of that, the observation group were given perioperative body temperature management. The body temperature, heart rate, pulse pressure and the difference of tumor markers of carcineombryonic antigen (CEA) and carbohydrate antigen19-9(CA199) before and after treatment were compared between the two groups. Results The difference value of temperature, heart rate and pulse pressure between 30 minutes after treatment and before treatment in the observation group were (3.7±0.4)℃, (12.4±2.7)bp/min and (5.6±1.9)mmHg respectively. The fluctuation of vital signs was lower than the control group, and the differences were statistically significant (t=6.062, 14.897, 10.392; P<0.01). The observation group patients' CEA was (52.8±2.4)μg/L, and CA199 was (106.1±5.3)U/ml after treatment, which were both lower than the control group, with statistical differences(t=31.415, 33.803; P< 0.05). Conclusions Perioperative body temperature management could significantly stabilize the body temperature, heart rate and pulse pressure, which could significantly promote intraperitoneal hyperthermic perfusion chemotherapy's curative effect for patient with abdominal malignant tumor.

This study was aimed to observe effects of different doses of D-galactosamine (D-GalN) plus lipopoly-saccharide (LPS) and blood coagulation changes among rat model of acute liver failure, in order to establish an ideal model of acute liver failure in rats. SD rats were randomly divided into the control group, D-GalN high, medium and low dose groups, with 10 rats in each group. Except the normal group, rats in other groups were injected with D-GalN plus LPS at different doses to induce acute liver failure. The mortality of rats was observed. The liver function and blood coagulation were detected from rat serum at 0 h, 12 h, 24 h, 48 h, and 72 h. HE stain was used in the observa-tion of changes on liver pathological changes. The results showed that the mortality of D-GalN high, medium and low dose groups within 72 h were 60%, 30%, 10%, respectively. There were significant differences on the serum content level of ALT, AST, TBIL, PT, INR, FIB from different dose groups at different time points and the normal group (P<0.05). However, the comparison among D-GalN high, medium and low dose groups showed no statistical difference on ALT and AST; while there were statistical differences on TBIL, PT, INR and FIB (P < 0.05). It was concluded that coagulation index was more stable in the liver failure model. Through observation on the liver function, blood coagulation and pathological morphology, the model of acute liver failure induced with medium dose of D-GalN plus LPS in SD rats at 48 h was more similar to the clinical symptom of acute liver failure. Therefore, the medium dose was the ideal model inducing dose.
