Objective To study the prognosis of patients with end-stage liver cirrhosis who using controlled cardiac death liver donor in situ liver transplantation. Methods Seven cases of transplants which used liver donated after cardiac death were done in our center. The preoperative and postoperative data were analyzed. The prognosis of these patients was observed. Results Except one recipient died of upper gastrointestinal bleeding at the 9th day after surgery, the remaining 6 patients were followed up for more than 12 months (mean 15.7 months) and the prognosis was satisfactory.Conclusion Patients can get good prognosis after the liver transplants with donated liver after cardiac death which meets the Maastricht Classification type Ⅲ.

Objective To describe the feasibility of biliary reconstruction methods and to explore the preventing and curing methods for biliary complications. Methods A total of 77 cases of living donor liver transplantation were included in our study for retrospective analysis. The operation types included right lobe contain middle hepatic vein (n=29), right lobe without middle hepatic vein (n=45), left lobe (n=1) and left lateral lobe transplantation (n=1). The biliary reconstruction was performed by duct-to-duct and Roux-en-Y epaticojejunostomy. Results Fifty-four grafts had 1 bile duct and 23 had multiple ones. The duct-to-duct biliary reconstruction was performed for 75 adult cases and T-tube drainage was used in 63 patients. Meanwhile, the conventional Roux-en-Y epaticojejunostomy was utilized for 2 pediatric patients. Total biliary complication incidence was 36.4% (28/77) and the complications included bile leakage (10.4%, 8/77) and biliary stricture (26.0%, 20/77).The rate of biliary complication was remarkably different between single hepatic duct group and multiple group (P<0.05). All the 8 patients suffering from bile leakage were cured by percutaneous bile drainage guided by ultrasound. By percutaneous balloon cholangioplasty and placing stent through the T-tube tract or endoscopic retrograde balloon cholangioplasty, the liver function of biliary stricture cases got better and most cases were cured. Conclusion Protecting the blood supply of bile duct at the cutting surface and harvesting one bile duct stump as much as possible can reduce biliary complication effectively. Radiate intervention treatment such as percutaneous balloon cholangioplasty and endoscope treatment etc. are effective for treatment of biliary complications.

Objective: To investigate the relationship between psoas muscle index (PMI) and early postoperative survival rate and the incidence of complications after liver transplantation in adults. Methods: The clinical data of 225 patients (male, n=184; female, n=41) underwent liver transplantation at the Organ Transplantation Department of First Central Clinic Institute of Tianjin Medical University from January 2014 to December 2016 were analyzed, retrospectively.Original disease: hepatitis B liver cirrhosis(44 cases), hepatitis C cirrhosis(10 cases), autoimmune liver cirrhosis(29 cases), other benign liver diseases(24 cases), liver cirrhosis with liver cancer(116 cases), hilar cholangiocarcinoma(1 case) and hepatic vascular sarcoma(1 case). The area of bilateral psoas muscle on the lower edge level of the third lumbar vertebral body was measured through preoperative CT image.The PMI was calculated using this formula: bilateral psoas muscle area (mm²)/the square of the body height (m²). According to the receiver operating characteristic curve and cut-off values, the male and female patients were divided into low PMI group and high PMI group respectively.The χ² test, Fisher exact test and t-test was used to compare the differences in perioperative data, survival rate and postoperative complications between the two groups, respectively. Results: There were 44 patients in the low PMI group, and 181 patients in the high PMI group. ICU time was longer (82.5(62.0-128.0) hours vs.69.1(56.0-104.0) hours; P=0.006) and preoperative blood urea nitrogen level (5.86(4.35-15.52) mmol/L vs. 4.94(4.05-7.06) mmol/L; P=0.012) was higher in the low PMI group than those in the high PMI group. Incidence rates of grade 5 complication (18.2%) and grade 4a complication (18.2%) were higher in the low PMI group, and 120-day cumulative survival rate was lower than that in high PMI group(81.8% vs. 95.6%, P=0.001). On the other hand, there were no significant differences in preoperative white blood cell count level, serum creatinine level, operative time, anhepatic period time, intraoperative blood loss, and incidence of postoperative grade 3 complications between the two groups(all P>0.05). Conclusions There is a significant correlation between PMI and early postoperative survival rate and incidence of complications.Patients with lower PMI has poor prognosis after liver transplantation.

Objective:To investigate the effect of fluid resuscitation and circulatory support, directed by different target mean arterial pressure (MAP), on abdominal blood flow, gastrointestinal function and inflammatory response in septic shock patients with hypertension.Methods:A prospective randomized controlled study was conducted. Hypertensive patients with septic shock admitted to the department of intensive care unit (ICU) of Liuzhou People's Hospital from January 1, 2019 to May 31, 2020 were enrolled. Patients were randomly divided into the low MAP groups (low standard group, LS group) or high MAP group (high standard group, HS group). According to the Surviving Sepsis Campaign Guidelines in 2016 and the updated guideline in 2018, all patients were given treatment of primary disease, fluid resuscitation, supportive management. The target MAP was 65-70 mmHg (1 mmHg = 0.133 kPa) in LS group, and was 75-80 mmHg in HS group. Acute gastrointestinal function injury (AGI) classification was performed on the 1st, 3rd and 7th day. The mean flow rate (Vm) and resistance index (RI) of superior mesenteric artery were evaluated using ultrasound, and the gastrointestinal function was dynamically evaluated using the modified single section ultrasonic gastric antrum method. The gastric antrum movement index (MI) and gastric empaging time (GET) were recorded. The levels of inflammatory markers in serum were detected by enzyme linked immunosorbent assay (ELISA), such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), procalcitonin (PCT) and vascular endothelial growth factor (VEGF). The target MAP, the days of use of vasopressors and the amount of fluid resuscitation were recorded.Results:A total of 208 hypertensive patients with septic shock were enrolled, including 109 in the LS group and 99 in the HS group. There were no significant differences in gender, age, acute physiology and chronic health evaluationⅡ (APACHEⅡ) score and sequential organ failure assessment (SOFA) score between the two groups when diagnosed. After treatment, there was no significant difference in AGI classification between the LS group and HS group on the 1st day. On the 3rd and 7th day, there were statistical differences between the two groups (3rd day: proportion of Ⅰ, Ⅱ, Ⅲ, Ⅳ grades were 25.69%, 56.88%, 11.93%, 5.50% in LS group, 15.15%, 54.55%, 25.25%, 5.05% in HS group, respectively, χ 2 = 7.900, P = 0.048; 7rd day: proportion of Ⅰ, Ⅱ, Ⅲ, Ⅳ grades were 44.96%, 49.54%, 3.67%, 1.83% in LS group, 31.31%, 52.53%, 11.11%, 5.05% in HS group, respectively, χ 2 = 8.178, P = 0.042). The Vm of superior mesenteric artery was higher and the RI was lower in the LS group than those in the HS group on day 1, 3 and 7 [Vm (cm/s): 21.72±3.02 vs. 19.50±2.83, 20.42±2.62 vs. 17.02±1.99, 26.52±2.70 vs. 22.47±4.03; RI: 0.86±0.05 vs. 0.92±0.04, 0.87±0.05 vs. 0.95±0.05, 0.81±0.03 vs. 0.85±0.03, all P < 0.01]. The MI was higher and the GET was shorter in the LS group than those in the HS group on day 3 and day 7 [MI: 3.00±0.33 vs. 2.60±0.29, 4.50±0.51 vs. 3.90±0.33; GET (minutes): 86.01±19.78 vs. 100.99±25.01, 71.00±16.37 vs. 84.98±20.18, all P < 0.01]. In addition, the levels of serum TNF-α, IL-6, PCT, VEGF were lower in the LS group than those in the HS group after 3 days of treatment [TNF-α (ng/L): 147.05±28.32 vs. 256.99±27.04, IL-6 (ng/L): 762.99±57.83 vs. 1 112.30±118.32, PCT (μg/L): 37.00±5.58 vs. 56.00±12.36, VEGF (ng/L): 123.00±19.78 vs. 167.01±21.55, all P < 0.05]. The target MAP was maintained at (68.02±4.71) mmHg in LS group, and (79.04±3.04) mmHg in HS group. The difference between the two groups was statistically significant ( P < 0.01). Compared with the HS group, the days of using vasopressors was shorter in LS group (days: 3.50±1.27 vs. 4.55±1.47), and the amountof fluid was reduced significantly (mL: 1 602.29±275.49 vs. 2 000.30±272.59, both P < 0.01). Conclusion:Maintaining a low target mean arterial pressure (65-70 mmHg) in hypertensive patients with septic shock can improve blood supply of superior mesenteric artery, protect the gastrointestinal function, reduce the level of inflammatory factors, and diminish the duration of using vasopressors and the amount of fluid.
