ABSTRACT

Along with the increasing quantity of patients with end-stage liver diseases year by year, as an efficacious treatment, the safety and efficacy of liver transplantation are critical issues to be considered. In addition, liver transplant techniques have become a new research hot spot. In recent years, liver transplant techniques are constantly innovating and developing with the unremitting efforts of researchers. Researchers have successively developed multiple liver transplant techniques, such as split liver transplantation, ischemia-free liver transplantation, liver xenotransplantation, domino liver transplantation, delayed total hepatectomy combined with liver resection and segment Ⅱ-Ⅲ liver transplantation, heterotopic auxiliary liver transplantation on splenic fossa and magnetic anastomosis. It has laid a foundation for expanding the donor pool, improving clinical efficacy of liver transplantation and enhancing the quality of life of liver transplant recipients. In this article, the exploration, development, innovation and improvement of liver transplant techniques were reviewed and prospected, aiming to provide reference for clinical application of liver transplantation.

ABSTRACT

Cholecystolithiasis is a common disease of the digestive system. In recent years, due to the changes in diet and daily living habits, the incidence of cholecystolithiasis in the world is rising gradually. Choledocholithiasis can form initially in situ, mainly due to infection and cholestasis, but also secondary to cholecystolithiasis or intrahepatic bile duct stones.Symptomatic gallstone disease in patients with laparoscopic cholecystectomy is the standard treatment.However, for patients with common bile duct calculi, traditional open surgery, laparoscopic combined choledochoscope, laparoscopic combined endoscopic and laparoscopic combined laser lithotripsy are all effective ways of treatment. But which one specific operation method is the best choice has yet to agree a consensus. In this paper, several different surgical treatment methods of common bile duct calculi are reviewed in order to provide certain reference value for clinical practice.

ABSTRACT

Bilioenterostomy is the one of the main therapy options for extrahepatic and perihilar biliary diseases(benign and malignant tumors, congenital biliary dilatation, inflammatory stricture of bile duct reconstructive drainage of bile duct after lesion and iatrogenic injury of bile duct) resection and is a common procedure for hepatobiliary surgery. It’s necessary to take a further consideration in the choice of operation type, anastomosis method, suture and the placement of biliary stent in the bilioenterostomy for the hepatobiliary surgeon, since the incidence of postoperative complications such as anastomotic stenosis and reflux cholangitis will increase on account of the difference and inappropriateness of these choices. Currently, the development of techniques relating bilioenterostomy has become more proficient and some viewpoints have been unified. However, there are still some controversies in clinical application. It is necessary for surgeon to make the appropriate and reasonable choice on the basis of the specific circumstances in patients.

ABSTRACT

Objective@#To explore the relationship between procalcitonin (PCT), C-reactive protein (CRP) and blood glucose (BG) levels and postoperative pancreatic fistula (POPF) in non-diabetic patients after pancreaticoduodenectomy (PD), and evaluate the clinical value of early multi-indicators combined prediction of pancreatic fistula.@*Methods@#The clinical data of 68 non-diabetic patients who underwent PD surgery from April 2016 to June 2018 in the First Affiliated Hospital of Harbin Medical University were retrospectively analyzed, including 42 males and 26 females, with average age of 58 years, age range from 26 to 80 years. According to the diagnostic criteria of POPF, the patients were divided into the pancreatic fistula group (n=17) and the non-pancreatic fistula group (n=51). The surgical related indicators, health economic indicators and PCT, CRP, and BG levels on preoperative and postoperative day 1, 3 and 5(POD1, POD3, POD5) were compared between two groups. Multivariate logistic regression analysis was used to screen out independent risk factors associated with POPF, and a weighted predictive model (wScore M) for predicting pancreatic fistula in non-diabetic patients was established by combining independent risk factors. The receiver operating characteristic (ROC) curves of each independent risk factor and prediction model were plotted to determine the cutoff value, area under the ROC curve (AUC), sensitivity, specificity, positive predictive value, negative predictive value, and individual risk factors were compared. And the predictive value of the multi-indicator combined prediction model.@*Results@#Univariate analysis showed that the pathological types of the tumor, the tumor size, the blood glucose level of POD3, the PCT level of POD1, POD3, POD5 and the CRP level of POD3, POD5 were statistically different (P<0.05). Multivariate analysis showed that PCT (P=0.004), CRP (P=0.031), and BG (P=0.005) levels of POD3 were independent risk factors of POPF. The AUC of the ROC were 0.967, 0.692, and 0.698, respectively. The sensitivity were 0.588, 0.706, and 0.647, respectively. The specificities were 0.863, 0.686, and 0.765, respectively. The positive predictive values were 52.9%, 70.6%, and 64.7%, respectively. The negative predictive values were 88.2%, 70.6%, and 76.5%; the AUC of the wScore M ROC curve was 0.877, the sensitivity was 0.706, the specificity was 0.863, the positive predictive value was 70.6%, and the negative predictive value was 86.3%. Compared with the non-pancreatic fistula group, the patients of the pancreatic fistula group with pancreatic fistula complications had prolonged hospitalization time and increased the total hospitalization cost, which were statistically different (P=0.039, 0.010).@*Conclusion@#PCT, CRP and BG are independent risk factors for POPF, and early combined prediction of multiple indicators (POD3)has good predictive value, which has significant clinical reference for optimal and effective interventions at early stage.

ABSTRACT

Objective@#To summarize the experience of treatment for blunt pancreatic trauma.@*Methods@#The clinical data of 52 patients with blunt pancreatic trauma admitted to the Department of Pancreatic and Biliary Surgery of the First Affiliated Hospital of Harbin Medical University from January 2013 to June 2018 were analyzed retrospectively.There were 40 male and 12 female patients, aging from 12 to 112 years with a median age of 35.5 years.According to the organ injury scale by American Association for the Surgery of Trauma(AAST) for pancreatic injury severity, 15 cases were in grade Ⅰ(28.8%), 20 cases were in grade Ⅱ(38.5%), 10 cases were in grade Ⅲ(19.2%),5 cases were in grade Ⅳ(9.6%) and 2 cases were in grade Ⅴ(3.8%). Isolated blunt pancreatic trauma occurred in 11(21.2%) patients including 5 cases of grade Ⅰ,5 cases of grade Ⅱ and 1 case of grade Ⅲ, and associated injuries existed in 41 patients(78.8%).@*Results@#Among 52 patients, 36 patients(69.2%) were transferred from other hospitals and 16(30.8%) patients were admitted through the emergency department. Finally, 49 patients(94.2%) were cured and 3 patients (5.8%) died.For the 15 cases of grade Ⅰ,9 patients were managed non-operatively, 5 cases underwent peritoneal lavage and drainage after surgery for the other injured abdominal organs, and 1 patient received percutaneous catheter drainage(PCD) with non-operative treatment. For the 20 cases of grade Ⅱ,4 cases only received non-operative treatment and 2 cases also received PCD. Besides, 2 cases underwent debridement and drainage for peripancreatic necrotic tissue and external drainage for pancreatic pseudocyst retrospectively after about 25 days of getting injured. As for patients who received exploratory laparotomy, 5 patients underwent suture repair associated with external drainage, and 7 patients were managed only with external drainage. For the 10 cases of grade Ⅲ,6 patients were cured through distal pancreatectomy and splenectomy with external drainage, while 2 patients underwent endoscopic retrograde cholangiopancreatography and ductal stenting, and the other 2 patients just received debridement and drainage for peripancreatic necrotic tissue.For the 5 cases of grade Ⅳ,2 patients underwent jejunostomy and abdominal cavity drainage, 1 patient had a pancreaticoduodenectomy with drainage,1 patient received suture repair of the pancreas and pancreaticojejunostomy, and 1 patient was managed with suture repair of the head of pancreas and external drainage.For the 2 patients of grade Ⅴ,1 patient received exploratory laparotomy and gauze compression packing hemostasis, and the other patient underwent pancreaticoduodenal repair, gastrointestinal anastomosis, duodenal exclusion surgery and external drainage.@*Conclusion@#According to the AAST classifications, associated injuries, physiological status and intraoperative situation, it could be better to make a comprehensive judgment, achieve early diagnosis and take appropriate individualized treatment strategy, and to improve the overall therapeutic effect for blunt pancreatic trauma.

ABSTRACT

Objective@#To examine the association of hyperglycemia and postoperative complications in non-diabetic patients underwent pancreaticoduodenectomy(PD).@*Methods@#The clinical data of 209 non-diabetic patients who underwent PD from January 2012 to June 2018 at Department of Pancreatic and Biliary Surgery, the First Affiliated Hospital of Harbin Medical University and met the inclusion criteria were retrospectively analyzed. According to the diagnostic criteria of postoperative hyperglycemia, the patients were divided into postoperative hyperglycemia group (167 cases, 79.9%) and control group(42 cases, 20.1%). The propensity score matching(PSM) method was used to eliminate the difference between groups(caliper value=0.02; 38 cases in control group including 30 males and 8 females with age of 59.0 years; 38 cases in postoperative hyperglycemia group including 32 males and 6 females with age of 61.0 years; 37 cases of pancreatic head carcinoma, 30 cases of periampullary carcinoma and 9 cases of benign diseases). A comparative analysis was applied for preoperative data, surgical related indicators and postoperative complication rates.The receiver operating characteristic(ROC) curve was used to calculate the area under the curve(AUC) of blood glucose values on postoperative day 1,3 and 5(POD1, POD3, POD5), to determine the high-risk blood glucose cutoff value of complications and to evaluate its sensitivity and specificity for the prediction of postoperative complications.@*Results@#Univariate analysis showed that the differences in gender, body mass index, preoperative blood glucose, and serum urea nitrogen levels were statistically significant before PSM.There was no significant difference in the preoperative data between the two groups after PSM. Compared with the control group, the incidence of postoperative pancreatic fistula (31.6% vs. 5.3%), abdominal infection(29.0% vs. 7.9%) and Clavien-Dindo Ⅲ-Ⅴ complications(31.6% vs.7.9%) were statistically different(χ2=7.092, P=0.008; χ2=4.290, P=0.038; χ2=5.316, P=0.021), respectively. According to the AUC on POD3, the blood glucose value≥8.860 mmol/L was an independent risk factor for pancreatic fistula with sensitivity of 58.3% and specificity of 76.9%, the blood glucose value ≥9.130 mmol/L was an independent risk factor for abdominal infection with sensitivity of 54.5% and specificity of 81.5% and the blood glucose value ≥7.685 mmol/L was independent risk factor of Clavien-Dindo Ⅲ-Ⅴcomplications with sensitivity of 75.0% and specificity of 57.7%.@*Conclusions@#Postoperative hyperglycemia in non-diabetic patients is associated with postoperative pancreatic fistula, abdominal infection, and Clavien-Dindo Ⅲ-Ⅴ complications.According to the early postoperative blood glucose value, the occurrence of postoperative pancreatic fistula, abdominal infection and Clavien-Dindo Ⅲ-Ⅴ complications can be effectively predicted.

ABSTRACT

Hepatic cellular carcinoma is the third most common cause of cancer deaths in China.Partial hepatectomy is still the most effective treatment for hepatic cellular carcinoma.The liver is an organ with strong regenerative ability,and its regenerative mechanism is very complex.Majority of patients with hepatic cellular carcinoma are accompanied by cirrhosis,and cirrhosis is an important factor affecting the regeneration of the remaining liver after surgery.Liver regeneration is obviously impaired under this condition.However,the anti-liver fibrosis mechanisms behind these processes have not been completely elucidated,the current treatment of fibrosis is merely supportive care,and thus further definition of the antiliver fibrosis related factors such as keratinocyte growth factor,hepatocyte growth factor,milk fat globule epidermal growth factor 8,collagen-binding vascular endothelial growth factor,ex vivo expansion of circulating CD34+ cells has far-reaching significance for improving their prognosis.This article mainly introduces some relevant factors associated with anti liver fibrosis,for later use of single factor or a combination of multifarious factors to resist liver fibrosis,to provide reference for improving the ability of remained liver regeneration after partial hepatectomy.

Objective@#To study the prognostic factors of delayed gastric emptying(DGE) after pancreaticoduodenectomy(PD) and construct a prognostic predictive model for clinical application.@*Methods@#Clinic data of 401 consecutive patients who underwent PD between January 2012 and July 2016 in the First Affiliated Hospital of Harbin Medical University were retrospectively collected and analyzed. The patients were randomly selected to modeling group(n=299) and validation group(n=102) at a ratio of 3∶1. The data of modeling group were subjected to univariate and multivariate analysis for prognostic factors and to construct a prognostic predictive model of DGE after PD. The data of validation group were applied to test the prognostic predictive model.@*Results@#DGE after PD occurred in 35 of 299 patients(11.7%) in the modeling group. The multivariate analysis of the modeling group showed that upper abdominal operation history(χ2=6.533, P=0.011), diabetes mellitus(χ2=17.872, P=0.000), preoperative hemoglobin <90 g/L(χ2=14.608, P=0.000) and pylorus-preserving pancreaticoduodenectomy(PPPD)(χ2=8.811, P=0.003) were associated with DGE after PD independently. A prognostic predictive model of DGE after PD was constructed based on these factors and successfully tested. The area under the receiver operating characteristic(ROC) curve was 0.761(95%CI: 0.666-0.856) of the modeling group and 0.750(95% CI: 0.577-0.923) of the validation group.@*Conclusions@#Upper abdominal operation history, diabetes mellitus, preoperative hemoglobin<90 g/L and PPPD are associated with DGE after PD independently. The preoperative assessment of a patient′s prognostic for DGE after PD is feasible. The model is a valid tool to take precautions against DGE after PD.
