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 investigate the clinical effect of simultaneous use of three endoscopes(laparoscope,choledochoscope,and duodenoscope)combined with holmium laser in the treatment of gallstones complicated with common bile duct stones.Methods A prospective randomized controlled study was carried out.A total of 80 patients with cholecystolithiasis combined with choledocholithiasis in our hospital from August 2022 to January 2024 were selected and divided into three-endoscope group(n=40)and two-endoscope group(n=40)according to random number table method.Patients in the three-endoscope group underwent laparoscopic cholecystectomy(LC)and laparoscopic common bile duct exploration(LCBDE)combined with holmium laser lithotripsy,primary closure of the common bile duct,endoscopic retrograde cholangiopancreatography(ERCP),and endoscopic nasobiliary drainage(ENBD),while the two-endoscope group underwent LC+LCBDE+T-tube drainage.The intraoperative bleeding volume,operation time,hospitalization time,hospitalization costs,and postoperative complications between the two groups were observed and analyzed.Results There was no significant difference in intraoperative bleeding volume between the two groups[(55.6±14.3)ml vs.(53.2±16.3)ml,t=0.703,P=0.484].The operation time of the three-endoscope group was significantly longer than that in the two-endoscope group[214.5(171.5,246.8)min vs.178.0(151.0,227.8)min,Z=-2.069,P=0.039].The length of hospital stay in the three-endoscope group was significantly shorter than that in the two-endoscope group[(13.2±3.3)d vs.(16.2±3.7)d,t=3.864,P=0.001].The hospitalization costs were significantly higher in the three-endoscope group than those in the two-endoscope group[39 316.0(32 338.5,43 421.0)yuan vs.33 717.0(30 873.3,37 813.3)yuan,Z=-3.272,P=0.001].There were no significant differences in the incidence of postoperative pancreatitis[2.5%(1/40)vs.2.5%(1/40),χ2=0.000,P=1.000],the incidence of bile leakage[7.5%(3/40)vs.2.5%(1/40),χ2=0.263,P=0.615],and residual stone rate[7.5%(3/40)vs.0.0%(0/40),P=0.241]between the two groups.Forty cases in the three-endoscope group were followed up for 2-20 months,with a median of 13 months.One case of stone recurrence occurred at 8 months after surgery.Forty patients in the two-endoscope group were followed up for 1-21 months,with a median of 15 months.There was 1 case of stone recurrence at 6 and 10 months postoperatively,respectively.There was no statistically significant difference in stone recurrence rate between the two groups[2.5%(1/40)vs.5.0%(2/40),χ2=0.000,P=1.000].Conclusions LC+LCBDE combined with holmium laser lithotripsy,primary closure of the common bile duct,ERCP,and ENBD in the treatment of cholecystolithiasis and choledocholithiasis can shorten the hospitalization time.The replacement of T-tube with nasobiliary duct protects the function of the Oddi sphincter,which is more in line with the concept of minimally invasive surgery and worthy of clinical application.

Objective:To explore the risk factors of short-term prognosis of severe Budd-Chiari syndrome (BCS) patients,established and verified the nomogram prediction model for these BCS patients and evaluated its clinical application value.Methods:This study is a retrospective cohort study. The clinical data of 171 patients with severe BCS diagnosed were retrospectively analyzed in the Department of Hepatopancreatobiliary Surgery First Affiliated Hospital of Zhengzhou University from January 2018 to December 2023. There were 105 males and 66 females, aged (52.1±12.8) years (range: 18 to 79 years). The patients were divided into two groups based on whether they died within 28 days: the death group ( n=38) and the survival group ( n=133). The risk factors for short-term death of patients were analyzed,and independent risk factors were screened by univariate and multivariate analysis. Furthermore,these factors were used to establish the nomogram prediction model. The area under the curve(AUC),the Bootstrap Resampling,the Hosmer-Lemeshow test and the Decision Curve Analysis(DCA) were used to verify the model′s differentiation,internal verification,calibration degree and clinical effectiveness,respectively. Results:Univariate and multivariate Logistics regression analysis showed that the history of hepatic encephalopathy,white blood cell,glomerular filtration rate and prothrombin time were independent risk factors ( P<0.05). The above factors were used to successfully establish the prediction model with 0.908 of AUC and 0.895 of the internal verification of AUC,indicating that the predictive model was valuable. The 0.663 P-values in the Hosmer-Lemeshow test indicated the high calibration degree of the model. The clinical effectiveness of the model was proved by the 18% clinical benefit population using the DCA curve with the 17% probability threshold. Conclusions:The independent risk factors are the history of hepatic encephalopathy,white blood cell,glomerular filtration rate and prothrombin time. An adequate basis was acquired by establishing a nomogram prediction model of the short-term prognosis of severe BCS,which was helpful for early clinical screening and identification of high-risk patients with severe BCS who could die in the short term and timely providing timely intervention measures for improving the prognosis.

OBJECTIVE: To evaluate the treatment and prognosis of sinonasal mucosal melanoma (SMM). METHOD: Clinicopathological data of SMM patients from January 1976 to December 2005 were analyzed retrospectively. Survival analysis was performed and Kaplan-Meier analysis was used to compare the effect of clinicopathological factors on survival using SPSS 18.0 software. A Cox model was applied for multivariate analysis. RESULT: The 3-year and 5-year overall survival (OS) rates of 68 cases of SMM were 36.1% and 29.4%, respectively. The 3-year and 5-year OS of patients who underwent surgery or biotherapy were significantly higher than that of patients who underwent other therapeutic regimens without surgery or without biotherapy, respectively. Multivariate analysis showed the patients with distant metastasis at first present or residual/recurrence had a worse prognosis than that without distant metastasis or residual/recurrence, respectively. Surgery and biotherapy were effective treatments for SMM. CONCLUSION SMM has a poor prognosis, especially in the patients with distant metastasis or residual/recurrence. Surgery or biotherapy may improve the prognosis of patients with SMM.
