Objective To preliminarily investigate the safety and efficacy of donor pancreas needle biopsy in simultaneous pancreas-kidney transplantation. Methods Clinical data of 7 cases undergoing donor pancreas biopsy were collected retrospectively. All cases underwent donor pancreas biopsy before or during simultaneous pancreas-kidney transplantation. Frozen section or paraffin sectioning techniques were used for tissue preparation, and hematoxylin-eosin and Masson staining were performed to histologically evaluate the donor pancreas. The quality of donor pancreas was comprehensively assessed by combining histological findings with the donor's clinical data. Postoperative follow-up data of 5 simultaneous pancreas-kidney transplant recipients were collected to summarize the safety of donor pancreas biopsy and the prognosis of transplant recipients. Results The 7 pancreas donors were aged 28 to 62 years, with a body mass index ranging from 20.76 to 27.68 kg/m². Liver ultrasound indicated fatty liver in 3 cases, while pancreatic ultrasound did not reveal any significant abnormalities. Among them, biopsy was performed on 2 donors after completion of pancreatic procurement and processing, and the frozen section histology showed moderate acute pancreatitis changes (edema of acinar cells, necrosis and inflammatory cell infiltration). Combined with a serum amylase level elevated more than 3 times the upper limit of normal value, these two donor pancreases were finally discarded. The remaining 5 cases underwent biopsy immediately after pancreatic vascular anastomosis during simultaneous pancreas-kidney transplantation, and histological evaluation was performed on paraffin-embedded sections. No biopsy-related complications (such as bleeding, pancreatic fistula, etc.) occurred after transplantation. One recipient died of severe infection 2 months after transplantation, while the other 4 recipients were followed up for more than 5 years, with well-functioning transplant kidneys and pancreases. Conclusions Donor pancreas biopsy is relatively safe, and the risk of biopsy-related complications after transplantation is controllable. Comprehensive assessment of donor pancreas quality by combining histological evaluation with the donor's clinical indicators is conducive to improving the accuracy of donor pancreas selection and organ utilization.

Objective:To evaluate the efficacy of modified splenic arteriovenous shunt surgery at the distal pancreatic tail in combined pancreas-kidney transplantation.Methods:A retrospective analysis was conducted on 24 recipients who underwent combined pancreas-kidney transplantation with the modified splenic arteriovenous shunt at the pancreatic tail from November 2023 to October 2024 (shunt group) and 231 recipients who received conventional splenic artery and vein ligation since 2016 (ligation group). The incidence of perioperative thrombosis and severe adverse events was compared between the two groups using the chi-square test or Fisher's exact test. Independent sample t-tests were performed to assess postoperative pancreatic and renal function recovery as well as blood perfusion in 15 recipients from the shunt group and 20 from the ligation group who underwent CT perfusion imaging (CTP).Results:The incidence of perioperative splenic arteriovenous thrombosis was lower in the shunt group (0) compared to the ligation group (4.76%, 11/231), though the difference was not statistically significant ( P=0.606). One month postoperatively, the shunt group demonstrated significantly lower serum amylase levels than the ligation group (99.61±19.62 vs. 148.20±70.67 U/L, P=0.018). However, at the time of CTP examination, serum lipase (67.87±32.35 vs. 45.11±17.94 U/L, P=0.014) and creatinine levels (131.79±26.41 vs. 112.1±24.98 μmol/L, P=0.034) were significantly higher in the shunt group. Urea nitrogen levels were also significantly higher in the shunt group both one month postoperatively (11.24±4.64 vs. 8.51±3.01 mmol/L, P=0.043) and at the CTP examination (10.41±1.78 vs. 6.87±1.91 mmol/L, P=0.001). Regarding pancreatic perfusion, blood volume in both the pancreatic head (15.99 ± 3.51 vs. 20.67 ± 5.47 ml/100 g, P = 0.024) and tail (17.19±4.24 vs. 27.40±19.80 ml/100 g, P=0.039) was significantly lower in the shunt group. After one minute of splenic artery perfusion, the shunt group exhibited significantly higher splenic artery blood flow (755.85±101.50 vs. 574.00 ± 142.06 ml·min -1· (100 g) -1, P<0.001) and blood volume (58.90 ±19.93 vs. 23.21±17.02 ml/100 g, P=0.007) compared to the ligation group. These differences persisted after two minutes of perfusion (blood flow: 793.83±68.57 vs. 503.78 ± 130.80 ml·min -1· (100 g) -1, P<0.001; blood volume: 64.22±15.74 vs. 34.32±20.39 ml/100 g, P=0.002). For the transplanted kidney, the shunt group had significantly lower blood flow (113.10±28.55 vs. 232.76±113.37 ml·min -1· (100 g) -1, P<0.001), blood volume (28.95±10.79 vs. 38.36±12.38 ml/100 g, P=0.047), and capillary surface permeability (PS) (26.49±16.57 vs. 43.02±20.37, P = 0.042) in the upper pole. Similar reductions in blood flow, blood volume, and PS were observed in the middle dorsal region ( P=0.018, 0.021, and 0.048, respectively) and lower pole ( P<0.001, P=0.048, and P=0.012, respectively). Conclusion:The modified splenic arteriovenous shunt at the pancreatic tail appears to be a safe and effective approach to reducing the risk of pancreatic graft thrombosis. This technique facilitates effective diversion of pancreatic parenchymal blood flow into the splenic vein, alleviating hyperperfusion of the transplanted pancreas. While renal blood perfusion was reduced postoperatively, it did not adversely affect renal function.

Objective:To explore the prognostic differences between liver resection and transarterial chemoembolization (TACE) in patients with Budd-Chiari syndrome (BCS) complicated by hepatocellular carcinoma (HCC) and to identify independent risk factors affecting patient survival.Methods:The clinical and follow-up data of 103 patients with stage Ⅰa-Ⅲa BCS complicated by HCC treated at the First Affiliated Hospital of Zhengzhou University from Aug 2015 to Sep 2023 were retrospectively analyzed.Results:Patients were divided into two groups based on their initial treatment choices: the liver resection group ( n=20) and the TACE group ( n=83). Before propensity score matching(PSM), the median overall survival in the liver resection group was 42 months longer than in the TACE group (74 months vs. 32 months, P=0.002). After PSM, the median overall survival remained significantly longer in the liver resection group by 39 months (74 months vs. 35 months, P=0.032). In terms of disease-free survival, before PSM, the liver resection group was 30-month longer than the TACE group (42 months vs. 12 months, P=0.001). After PSM, the difference in median disease-free survival between the two groups was 23 months (35 months vs. 12 months, P=0.018). Multivariate Cox regression analysis identified treatment modality and maximum tumor diameter as independent risk factors for overall survival, while treatment modality was the only independent factor for disease-free survival. Conclusions:Liver resection significantly prolongs both overall survival and disease-free survival in resectable HCC in BCS patients compared to TACE. Treatment modality and tumor size are key prognostic factors influencing overall survival.

Objective To discuss the efficacy and safety of transarterial chemoembolization(TACE)and hepatic arterial infusion chemotherapy(HAIC)combined with tyrosine kinase inhibitors(TKI)and immune checkpoint inhibitors(ICI)for advanced hepatocellular carcinoma(HCC).Methods A total of 101 patients with unresectable HCC,who were admitted to the Affiliated Cancer Hospital of Harbin Medical University of China between January 2021 and October 2022 to receive treatment,were enrolled in this study.Of the 101 patients,50 received TACE+TKI+ICI therapy(TACE+TKI+ICI group)and 51 received HAIC+TKI+ICI therapy(HAIC+TKI+ICI group).The overall survival(OS)and the progression-free survival(PFS)were compared between the two groups,and the adverse events were analyzed to assess the safety of the therapeutic scheme.Results The median PFS in the TACE+TKI+ICI group was 12.0 months,which in the HAIC+TKI+ICI group was 11.0 months(P=0.030).The median OS was not achieved in the TACE+TKI+ICI group,which in the HAIC+TKI+ICI group was 14.6 months(P=0.005).The most common adverse effects in the TACE+TKI+ICI group were the elevation of total bilirubin(46.0％)and hepatic function injury(26.0％),which in the HAIC+TKI+ICI group were the decrease of albumin level(62.7％),fatigue(39.2％),and gastrointestinal reactions(31.4％).Conclusion For the treatment of advanced HCC,the therapeutic scheme of TACE+TKI+ICI has a better long-term survival benefits and the therapeutic scheme of HAIC+TKI+ICI can better maintain the liver function reserve of the patients.Neither therapeutic scheme shows any unexpected toxicity,and both therapeutic schemes have high clinical safety.(J Intervent Radiol,2024,33:543-548)

Objective To evaluate the efficacy and safety of mFOLFOX-based hepatic arterial infusion chemotherapy(HAIC)combined with tyrosine kinase inhibitors(TKIs)and immune checkpoint inhibitors(ICIs)in the treatment of advanced hepatocellular carcinoma(HCC)complicated by portal vein tumor thrombus(PVTT).Methods The clinical data of 37 patients with HCC complicated by PVTT,who received mFOLFOX-based HAIC combined with TKI and ICI at the Department of Intervention,Affiliated Cancer Hospital of Harbin Medical University of China between January 2021 and January 2023,were retrospective analyzed.The primary endpoint was the objective remission rate of PVTT response,and the secondary endpoints included the 6-month survival rate,one-year survival rate,and overall survival(OS).The treatment-related adverse events and complications were evaluated.PVTT response was assessed using ITK-SNAP software,life table was used to calculate 6-month and one-year survival,Kaplan-Meier survival curve was used to assess overall OS,and logistic regression analysis and Cox regression analysis were used to analyze the risk factors associated with PVTT response and OS.Results Of the 37 patients,complete resolution of PVTT volume(CR)was obtained in 7(18.92％),and reduction of PVTT volume over 50％was obtained in 21(56.76％).The objective remission rate(ORR)of PVTT was 75.68％.The 6-month survival rate was 89％,the one-year survival rate was 66％,and the median OS was 15.8 months.Univariate analysis indicated that cavernous degeneration of portal vein(CTPV)was correlated with PVTT response(P=0.010).The Child-Pugh score(P=0.010)and the presence of PVTT response(P=0.004)to treatment were the important factors for predicting OS.Multivariate analysis revealed that the preoperative volume of cancer thrombus(P=0.033),cavernous degeneration of portal vein(P=0.007)were the important factors for predicting the PVTT response,and the Child-Pugh score(P=0.035)and the presence of PVTT response during treatment(P=0.015)were the important factors for predicting OS.The most common adverse reactions related to HAIC were oxaliplatin-related pain(n=30,80％)and thrombocytopenia(n=22,59％),among them 10patients(27％)developed grade Ⅲ painand4patients(11％)developed grade Ⅲ thrombocytopenia.The pain could be alleviated by slowing down the pump velocity and corresponding pain relief treatment.The targeted therapy and immunotherapy-related common adverse reaction was hand and foot reactions(n=16,45％),among them 6 patients(16％)developed grade Ⅲ hand and foot reactions.Conclusion FOLFOX-based HAIC combined with targeted therapy and immunotherapy can obtain a 75.68％ORR of PVTT,which provides more therapeutic options for intrahepatic tumors.

One case of COVID-19 infection secondary to pulmonary mucormycosis in a recipient of simultaneous pancreas-kidney transplantation was described. Early identification of the pathogen was achieved by metagenomic next-generation sequencing. On the basis of disease status and liver function changes, targeted treatments included intravenous amphotericin B liposome, amphotericin B nebulization& gargling and subsequently a maintenance therapy of oral posaconazole. This regimen resulted in the absorption of lung infection, stabilization of transplanted pancreas function and reduced levels of creatinine and urea as compared to pre-infection period. The therapeutic efficacy was decent.
