ABSTRACT

Objective Toidentify factors contributing to posthepatectomy liver dysfunction (PHLD),focusing on the Functional remnant liver volume to spleen volume ratio (FreLSVR).Methods The clinical data of 74 patients undergoing precise liver resection from January 2016 to October 2017 were retrospectively analyzed.IQQA liver system was used to reconstruct the liver and spleen 3D image by using patients' preoperative abdominal CT image data.Tumor volume,3D estimated functional residual liver volume,spleen volume and FreLSVR were measured and calculated.Preoperative and postoperative liver function test,blood coagulation function test,operation time,intraoperative blood loss,and the volume of daily postoperative abdominal drainage were recorded.Correlations between multiple parameters and PHLD were analyzed.Results PHLD occurred in 16 (21.6%).Single factor analysis revealed that the standardized residual liver volume ratio (P<0.05),FreLSVR (P<0.05) and preoperative AST value (P<0.05) were correlated with postoperative hepatic insufficiency.Multivariate regression analysis showed that FreLSVR (OR=0.535,95%CI=0.305~0.936,P<0.05) was the only independent factor of PHLD.In the ROC curve analysis for FreLSVR,a cut-off value of 2.56 (AUC=0.824,Sensitivity 81.1%,specificity 71.7%.) was the appropriate value for predicting the risk of PHLD according to Youden index.Then the patients were regrouped according to this cut-off value.Compared with the FreLSVR>2.56 group (53 cases),the highest postoperative INR value (1.46± 0.19 to 1.29± 0.29,t=-2.405,P<0.05) was higher that of FreLSVR≤2.56 group,and the amount of average daily abdominal drainage in one and two weeks after operation was higher,(188.0(79.2 ~ 375.1)ml to 96.0(46.5 ~ 179.3)ml,P<0.05) and (207.2(125.6 ~ 827.1)ml to71.8(14.0 ~ 179.8) ml,P<0.05),respectively.Conclusion FreLSVR has significant correlation with postoperative hepatic dysfunction,and provides guidance for the safety of liver resection in the future.

ABSTRACT

The percutaneous transhepatic portal approach is the most commonly used technique for islet transplantation, largely owing to its safety and minimally invasive characteristic. Bleeding complications after islet transplantation are rare. A case of type 1 diabetes mellitus (T1DM) was treated in Tianjin First Center Hospital, who had a massive intra-abdominal hemorrhage after percutaneous transhepatic portal vein catheterization for islet transplantation. Through the review of the overall development of the case, we aim to improve the awareness of the complications of islet transplantation, to reduce the incidence of complications after percutaneous transhepatic portal vein transplantation, and to provide experience.

ABSTRACT

Objective To evaluate the indications and results of liver transplantation ior benign liver tumors.Methods From Jan 2001 to Dec 2014,16 patients of inoperable severely symptomatic benign liver tumors underwent liver transplantation in our department.There were 10 cases of polycystic liver disease,2 cases of hepatic epithelioid hemangioendothelioma,1 case of hepatic cavernous hemangioma,1case of liver mesenchymal hamartoma,1 case of hilar bile duct mucinous cystadenoma,1 case of hepatic adenoma.Results 3 cases were dead in the perioperative period.The remaining patients were alive and discharged with normal perioperative liver and kidney function.One case of polycystic liver lost to follow-up,the remaining 12 patients were all alive at the end of a follow-up of 17 to 161 months,with fully active life style.Conclusions Liver transplantation is an effective and sometimes the only treatment option for unresectable and symptomatic benign liver lesion.

ABSTRACT

Objective To study the clinical treatment and prognosis of de novo liver cancer following renal transplantation.Methods The clinical data of 15 patients who developed de novo liver cancer after renal transplantation carried out prior to treatment of liver cancer at the First Center Hospital of Tianjin between June 2006 and June 2016 were retrospectively studied.These patients were diagnosed to have liver cancer ranging from 23 to 98 months after renal transplantations,with an average of (42.5 ± 29.7) months.Two patients were diagnosed within 2 years,7 within 5 years,and 6 over 5 years after renal transplantation.Results Three patients underwent transcatheter arterial chemoembolization (TACE) and 12 patients underwent surgical resection which included right/left hemihepatectomy (n =5),hepatic segment resection (n =4),and tumor enucleation (n =3).Postoperative histopathology confirmed hepatocellular carcinoma in 8 patients,cholangiocarcinoma in 1 patient,and mixed liver cancer in 3 patients.Among the 12 patients who initially underwent'curative'surgery,3 patients died from recurrent cancer 8,16,25 months after surgery,respectively.The remaining 9 patients were still alive with a follow-up which ranged from 0.6 to 65-month.The 3 patients who underwent TACE were alive for 4,7 and 13 months,respectively.Conclusions De novo liver cancer were usually asymptomatic and had a rapid onset.The optimal clinical management which includes early diagnosis,appropriate therapy with immunosuppression and renal function preservation can result in good long-term survival.

ABSTRACT

The use of laparoscopic liver resections for benign and malignant diseases has spread worldwide.As in open liver surgery,anatomical orientation and the ability to control intraoperative challenges as bleeding have to be combined with expertise in advanced laparoscopic techniques.We provide an overview regarding the literature on laparoscopic liver resection for benign and malignant liver tumors with the aim to discuss the current standards and define remaining challenges.Laparoscopic liver resection is feasible and safe in selected patients and experienced hands.The minimal invasive approach offers benefits in perioperative shortterm outcome without compromising oncological outcomes compared to open liver resections.Further randomized trials are needed to formally prove these statements and to define the optimal indication and techniques for the individual patient.

ABSTRACT

Objective To probe the correlation between preoperative pulmonary dysfunction and postoperative pulmonary complications in patients of orthotopic liver transplantation. Methods From August 2008 to June 2009, 71 orthotopic liver transplantation patients were studied. Preoperative pulmonary function and its relationship with postoperative pulmonary complications were analyzed.Results Preoperatively 65 out of 71 patients had abnormal lung functions, suffering from pulmonary diffusing capacity reduction (65 cases, 91.5% ), followed by reduction of restrictive ventilation function (30 cases, 42. 2% ), small airway function reduction ( 28 cases, 39.4% ), and obstructive ventilatory function reduction (21 cases, 29. 6% ). The incidence of postoperative pulmonary complications was 56. 3% including: pulmonary atelectasis, pneumonia, acute respiratory failure. The incidence of posttransplantation pulmonary complications in patients with pulmonary restrictive or obstructive ventilation function reduction was higher than in normal group (x2 = 6.703, P= 0.010; x2 = 4.768, P = 0.029), and there was significant difference in pulmonary complication rate between groups of moderate and severe diffusing capacity reduction and mild reduction and normal range (x2 = 8.478, P = 0.004 ).Conclusions Preoperative pulmonary function abnormality in patients before liver transplantation such as pulmonary ventilatory function reduction (VCmax < 80% or FEV1.0 < 80% ) and moderate to severe pulmonary diffusing capacity reduction (TLCOSB < 60% ) predicts higher incidence of postoperative pulmonary complications.
