The pancreatico-enteric anastomisis has always been a great concern in pancreatoduodenectomy,even been called "Achilles heel".Pancreatic surgeons are interested in improving the anastomosis technique to prevent the pancreatic fistula rate.More than a hundred of anastomosis techniques were reported,authors reviewed the history of pancreatico-enteric anastomisis and divided it into three historical stages,as well as summarized the characteristics of each stage.At the same time,auhors introduced the most representative anastomotic techniques and conccpts in each period.

Objective:To evaluate the clinical application efficacy of four-stitch cholangiojejunostomy.Methods:Of 38 patients who received four-needle biliary and enterointestinal anastomosis in the Department of Hepatobiliary Surgery, Yuebei People's Hospital Affiliated to Shantou University Medical College from November 2016 to April 2020 were included, and the diseases, surgical methods and postoperative complications of four-needle biliary and enterointestinal anastomosis were analyzed.Results:There were 26 males and 12 females with an average of 57.3(44-77) years. Among 38 patients, there were 12 hilar cholangiocarcinoma patients, 10 pancreatic head cancer, 9 duodenal papillary cancer, 4 intrahepatic and extrahepatic bile duct stones, 1 pancreatic cystic adenoma, 1 gastric cancer invading pancreatic head and 1 gallbladder carcinoma. The procedure included pancreatoduodenectomy in 20, radical resection of hilar cholangiocarcinoma in 12, hepatectomy with biliary-enteric anastomosis in 4, radical resection of gastric cancer combined with pancreaticoduodenectomy in 1, radical resection of gallbladder carcinoma in 1. One, two and three ductal openings were anastomosed in 27, 7 and 4 patients, respectively. 10 patients have bile duct diameter <6 mm. Postoperative anastomotic leakage occurred in 1, and all patients were received followed-up visit for 2 months to 4 years without anastomotic stenosis.Conclusion:Four-stitch cholangiojejunostomy is simple, safe, effective, and convenient for small biliary ductal surgeries.

Objectives:To examine the efficacy of terminal branches portal vein embolization(TBPVE) for the increment of FLR in hepatocellular carcinoma (HCC) patients and to introduce its clinical value with transcatheter chemoembolization(TACE) in the treatment of HCC patients without surgery.Methods:One hundred and fifty HCC patients from three clinical centers of china underwent TBPVE technique from December 2016 to May 2021,including 89 males and 61 females. The average age was 51.9 years(range:18 to 79 years).One hundred and one patients were diagnosed with a background of HBV infection,including 27 patients with portal venous hypertension.TACE was performed simultaneously with TBPVE in 102 patients.Fifty-three patients underwent hepatectomy,who were subdivided into HBV positive and HBV negative groups,with TACE and without TACE groups to analyze the increment of future liver remnant (FLR), complications and survival data.These data were also analyzed in other 97 patients without hepatectomy.Results:All the patients reached adequate FLR successfully in 14 days after TBPVE including patients with portal venous hypertension.The average increment rates of FLR was 56.2% in 7 days and 57.8% in 14 days after TBPVE. There was no significant difference neither between HBV positive and HBV negative groups(7 days:(55.0±27.3)% vs.(57.8±20.9)%, t=0.885, P=0.373; 14 days:(57.3±24.6)% vs.(58.3±23.7)%; t=0.801, P=0.447),or between with TACE and without TACE groups(7 days:(62.3±26.3)% vs. (48.8±20.6)%; t=1.788, P=0.077;14 days:(64.4±25.0)% vs.(55.2±23.1)%; t=1.097, P=0.257).The morbidity and mortality rates were 20.8% and 1.9% in patients with hepatectomy.The 1-,3-year overall survival(OS) and disease-free(DFS) rates were 87.5%,64.5% and 64.7%,40.6% for patients underwent surgery.There was no significant difference of 1-,3-year OS and DFS between HBV positive and negative groups,but there were different between TACE and without TACE groups.The 1-,3-year OS for patients underwent TBPVE and TACE but without surgery were 80.1%, 53.7%. Conclusion:TBPVE is a good alternative technique for modulation of FLR for staged hepatectomy even in HBV positive HCC patients and can be applied with TACE procedure simultaneously as an option treatment for patients with no intend to surgery.

Objective:To investigate the clinical characteristics of 130 children with severe SARS-CoV-2 infection in Yunnan province after the relaxation of non-pharmaceutical interventions, and analyze the risk factors for mortality.Methods:This study is a retrospective case summary that analyzed the demographic data, underlying diseases, clinical diagnoses, disease outcomes, and laboratory results of 130 children with severe COVID-19 infections admitted to nine top-tier hospitals in Yunnan Province from December 2022 to March 2023. According to the prognosis, the patients were divided into survival group and death group. The clinical and laboratory data between the two groups were compared, and the risk factors of death were evaluated. The χ2 test and Mann-Whitney U test were employed to compare between groups, while Spearman correlation test and multiple Logistic regression were used to analyze the risk factors for death. The predictive value of independent risk factors was evaluated by receiver operating characteristic curve. Results:The 130 severe patients included 80 males and 50 females with an onset age of 28.0 (4.5, 79.5) months. There were 97 cases in the survival group and 33 cases in the death group with no significant differences in gender and age between the two groups ( P>0.05). Twenty-five cases (19.2%) out of the 130 patients had underlying diseases, and the number with underlying diseases was significantly higher in death group than in survival group (36.4% (12/33) vs. 13.4%(13/97), χ2=8.36, P=0.004). The vaccination rate in the survival group was significantly higher than that in the death group (86.1% (31/36) vs. 7/17, χ2=9.38, P=0.002). A total of 42 cases (32.3%) of the 130 patients were detected to be infected with other pathogens, but there was no significant difference in the incidence of co-infection between the death group and the survival group (39.3%(13/33) vs. 29.9% (29/97), χ2=1.02, P>0.05). Among the 130 cases, severe respiratory cases were the most common 66 cases (50.8%), followed by neurological severe illnesses 34 cases (26.2%) and circulatory severe 13 cases (10%). Compared to the survival group, patients in the death group had a significantly higher levels of neutrophil, ferritin, procalcitonin, alanine aminotransferase, lactate dehydrogenase, creatine kinase isoenzyme, B-type natriuretic peptide, interleukin-6 and 10 (6.7 (4.0, 14.0) vs. 3.0 (1.6, 7.0)×10 9/L, 479 (298, 594) vs. 268 (124, 424) μg/L, 4.8 (1.7, 10.6) vs. 2.0 (1.1, 3.1) μg/L, 66 (20, 258) vs. 23 (15, 49) U/L, 464 (311, 815) vs. 304 (252, 388) g/L, 71(52, 110) vs. 24(15, 48) U/L, 484 (160, 804) vs. 154 (26, 440) ng/L, 43 (23, 102) vs. 19 (13, 27) ng/L, 216 (114, 318) vs. 86 (45, 128) ng/L, Z=-4.21, -3.67, -3.76, -3.31, -3.75, -5.74, -3.55, -4.65, -5.86, all P<0.05). The correlated indexes were performed by multivariate Logistic regression and the results showed that vaccination was a protective factor from death in severe cases ( OR=0.01, 95% CI 0-0.97, P=0.049) while pediatric sequential organ failure assessment (PSOFA) ( OR=3.31, 95% CI 1.47-7.47, P=0.004), neutrophil-to-lymphocyte ratio (NLR) ( OR=1.56, 95% CI 1.05-2.32, P=0.029) and D dimer ( OR=1.49, 95% CI 1.00-1.02, P=0.033) were independent risk factors for death (all P<0.05). The area under the curve of the three independent risk factors for predicting death were 0.86 (95% CI 0.79-0.94), 0.89 (95% CI 0.84-0.95) and 0.87 (95% CI 0.80-0.94), all P<0.001, and the cut-off values were 4.50, 3.66 and 4.69 mg/L, respectively. Conclusions:Severe SARS-CoV-2 infection can occur in children of all ages, primarily affecting the respiratory system, but can also infect the nervous system, circulatory system or other systems. Children who died had more severe inflammation, tissue damage and coagulation disorders. The elevations of PSOFA, NLR and D dimer were independent risk factors for death in severe children.

In order to facilitate the treatment strategies for biliary tract injury, hilar cholangiocarcinoma, bile duct tumor thrombus, cholangiocellular carcinoma and bile duct cystic dilatation, many classifications have been made, even more than 10 types for one disease. Each type is represented by numbers or English alphabet, which are not only confusing but also difficult to remember. The Academician Mengchao Wu divided the liver into five sections and four segments base on its anatomy, this classification is very direct and visual, thus had been using till now. In order to overcome those complicated problems, it is considered to develop a new classification based on actual anatomic location similar to that for liver cancer, which is easy to remember and to directly determine the treatment strategy. All kinds of classifications have their own characteristics and advantages and disadvantages. This practical classifications avoid the complexity and may be useful for clinicians.
