The bovine jugular valved conduit was used to reconstruct the right ventricular outflow tract. selleck compound Results There was one early death due to sudden cardiac arrest at the night of surgery day. The remaining 5 patients were successfully recovered and discharged. Follow-up of survivors ranged from 3 to 13 months. Echocardiographic follow-up demonstrated the flow velocity across the mitral valve position was 1.5 to 2.3 m/s, with a means gradient of 4 to 6 mmHg (1 mmHg=0.133 kPa). Four patients showed mild mitral insuffiency, normal left atrium and ventricle size and left ventricle ejection fraction.One patient had moderate mitral insuffiency, pulmonary valve endocarditis, and reduced left ventricle ejection fraction. The clinical symptoms of all survivals improved significantly and the weight gain were satisfactory. Conclusion Pulmonary autograft mitral valve replacement may be a feasible and effective remedial surgical strategy for young infants with intractable congenital mitral valve lesions.Objective To examine the safety and clinical efficacy of ultrasound-guided irreversible electroporation (IRE) using the open surgery approach, after induction chemotherapy, in the treatment of locally advanced pancreatic cancer (LAPC) . Methods The data of 64 LAPC patients who underwent ultrasound-guided IRE using the open surgery approach after induction chemotherapy at Department of Pancreatobiliary Surgery, Sun Yat-sen University Cancer Center from August 2015 to March 2019 were retrospectively analyzed. The study comprised of 30 males and 34 females, with median age of 58.5 years old (range 34 to 87 years old) , were included in this study.The tumor was located in the pancreatic head and body/tail in 30 and 34 patients, respectively.The largest recorded tumor size was 6.1 cm (≤4.0 cm n=35; >4.0 cm n=29) .To create an electric field around the tumor, Two to six probes were parallelly inserted into each patient’s tumor, based on the size of the tumor, at a distance of 2 cm apart through the transverse mesoche entire cohort was 20.3% and all were classified as grade B.Of them, pancreatic fistula, incisional infection, and upper gastrointestinal hemorrhage were observed in 7, 4, and 2 cases, respectively.The rate of complications for patients in the primary and secondary treatment groups were significantly different (10/15 vs. 6.1%) , respectively (χ(2)=26.01, P less then 0.01) .Further, two deaths were observed after IRE in the primary treatment group, while none was observed in the secondary treatment group. Conclusions Ultrasound-guided IRE using the open surgery approach after induction chemotherapy is found to be safe and effective in treating patients with LAPC.However, these findings should be validated in prospective randomized trials before wide clinical application.Objective To examine the surgical approach, practical cognition as well as clinical effect of the orthotopic resection for laparoscopic pancreatoduodenectomy(OLPD). Methods From March 2019 to December 2019, 32 cases were treated with laparoscopic pancreatoduodenectomy (LPD) in a novel approach without mobilization of pancreatoduodenum in Pancreas Center of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine.There were 16 male patients and 16 female patients.The mean age was (64.8±9.5) years old.Body mass index was 14.9 to 31.0 kg/m(2).All patients were diagnosed as ampullary or pancreatic head tumors and were not unresectable cases.In the surgical strategy, Kocher’s dissociation, turning and pulling of the pancreaticoduodenal region, was not performed first.Anatomy in situ, separation of vessels which enter and exit from pancreas, separation of lymphatics and isolation of tumors were carried out in priority through the combined middle and left posterior approaches.Finally, the pancreatiive better treatments and results.Objective To examine the value of serum protein induced by vitamin K absence or antagonist-Ⅱ (PIVKA-Ⅱ) detection in the early diagnosis and surveillance of hepatocellular carcinoma (HCC). Methods The clinical data of 215 patients with HCC admitted to Department of Hepatobiliary-Pancreatic Surgery of China-Japan Union Hospital of Jilin University from October 2017 to May 2018 were analyzed retrospectively. There were 172 males and 43 females, aged of (59.0±9.3) years old (range 34 to 86 years old). In addition, there were 85 non HCC patients were enrolled in the control group, 42 males and 43 females, aged (54.2±11.3) years old (range 22 to 80 years old). The blood sample of 3 ml was drawn from the elbow vein at 6∶00 am on the next day of admission, and then was kept in low temperature away from light, and sent for PIVKA-Ⅱ detection on the same day. The positive value of AFP was ≥20 μg/L and PIVKA-Ⅱ was ≥32 AU/L. The data were analyzed statistically by χ(2) test, t test or rank sum test. The correlation betweeA-Ⅱ detection was significantly sensitive than AFP in the earlier stage of HCC. Combined detection of PIVKA-Ⅱ and AFP can effectively improve the diagnostic rate of HCC in all stages. The significant elevation of PIVKA-Ⅱ is also helpful to determine the tumor aggressiveness, vascular invasion and prognosis of HCC patients.Objective To examine the safety and effectiveness of ultrasound-guided percutaneous radiofrequency ablation in the treatment of liver malignant tumor under subcardiac. Methods The clinical data of 26 patients (31 tumors) with subcardiac liver malignant tumors who underwent ultrasound-guided percutaneous radiofrequency ablation from January 2017 to October 2019 at the Affiliated Tumor Hospital of Zhengzhou University were retrospectively analyzed. There were 21 males and 5 females. The age was 55 years old (range 40 to 77 years old) .There were 14 cases of primary liver cancer and 12 cases of metastatic liver cancer. The maximum diameter of tumor was (2.3±1.0) cm (range 1.0 to 4.2 cm) .According to the maximum diameter of the tumor, 1∶1 match was made between 27 non-subcardiac patients admitted at the same time and a total of 36 liver malignant tumors. subcardiac tumor is defined as tumor ≤1 cm from pericardium in sagittal or coronal imaging. The ablation effect and complications were recorded, and the one-time complete ablation rate, main technical efficiency and complications were evaluated.
