We here report 3 cases successfully treated with transjugular intrahepatic portosystemic shunt using Viatorr stent. The 3 patients were had a diagnosis of liver cirrhosis with portal vein hypertension, and presented with black stool and hematemesis. After the treatment, the patients' portal vein pressures were decreased without black stool or hematemesis. Our success demonstrate the feasibility of using Viatorr stent in transjugular intrahepatic portosystemic shunt.

OBJECTIVE: To assess the clinical application of preoperative retrograde portal venography for children with cavernous transformation of the portal vein (CTPV). METHODS: The clinical data of 8 cases of CTPV admitted in the Children's Hospital of Zhejiang University from January 2018 to September 2019 were retrospectively analyzed. Preoperative retrograde portography was performed to determine the corresponding vascular morphology and size of portal vein system. If the retrograde portography showed that the left branch of the shadow portal vein was unobstructed and its diameter was greater than 3 mm, Rex shunt would be performed after anatomic exploration of Rex recess; if retrograde portography showed that the diameter of left portal vein was less than 3 mm, but the diameter of left renal vein dissected during shunt operation was greater than 5 mm, Warren operation was selected. The patients were followed up for 1, 3 and 6 months after discharge, and then were followed up every 6 months. RESULTS: Retrograde portal venography was successfully performed in 8 child patients.The anatomical position and size of main portal vein and its left and right branches, left renal vein and other important vessels were determined. Among them, there was the well-developed left and right branches of portal vein in 4 child patients, in which the left and right branches of portal vein converged together, but did not communicate with the main portal vein. In addition, the left branch diameter of the portal vein was greater than 3 mm, and the anatomical exploration results during shunt were consistent with it, so Rex shunt was performed. In the other 4 cases, the left branch diameter of the portal vein was small (less than 3 mm) in 3 cases, and the right branch was not clearly developed. Moreover, the left branch of the portal vein was poorly developed and almost occluded in 1 case. However, the left renal vein in these 4 child patients was well developed, the blood flow was unobstructed and the diameter was greater than 5 mm, so Warren operation was performed. Seven patients recovered well after the operation, and the other one had digestive tract rudimentary one year after operation, and the condition was stable after conservative treatment. CONCLUSIONS The preoperative retrograde portal venography can be used to evaluate the portal vein system in children with CTPV, which provides important clinical basis for making appropriate treatment plan before surgery.

Clinical practice using associating liver partition and portal vein ligation for staged hepatectomy(ALPPS) or its modified procedures in treatment of primary hepatocellular carcinoma(HCC) with insufficient future liver remnant(FLR) in the past 10 years has failed to meet our expectations both in achieving decreased perioperative complications and mortality.The efficacy of ALPPS in improving long-term survival outcome of HCC still remains poor.Due to the trauma of two surgery within a short period,and patients with inadequate FLR are all diagnosed at advanced disease stages,ALPPS can only achieve surgical rather than biological tumor-curability.Previous studies have demonstrated comparable 5-year survival rates between early and advanced stages of HCC who underwent regional treatments.Therefore,tumor biological conversion is the key strategy prior to liver remnant volume conversion in improving treatment outcomes for HCC patients with insufficient FLR.Target therapy,immunotherapy together with locally treatment were expected to improve the conversion efficacy.Looking back at the development of ALPPS for the last decade,the rapid proliferation of FLR should be passed on,while the technology costs high risks and result in poor long-term outcome must be cautiously selected.

Pancreatic cancer is a major problematic concern among all forms of gastrointestinal malignancies because of its poor prognosis. Although significant progress has been made in the surgical treatment in terms of increased resection rate and decreased treatment-related morbidity and mortality, the true survival rate still remains below 5% today. Surgical options for pancreatic cancer are based on the its unique anatomy and physiology, catastrophic tumor biology, experience of surgeon, and status of patients. Four main options exist for the surgical treatment of pancreatic cancer. These include standard "Whipple" pancreaticoduodenectomy (PD), pylorus preserving PD (PPPD), distal pancreatectomy (left-side pancreatectomy), and total pancreatectomy according to the location of tumor. Portal vein involvement by tumor is regarded as an anatomical extension of disease, and en bloc resection of portal vein with tumor is recommended if technically feasible, which is stated in 2002 AJCC tumor staging for pancreatic cancer. In comparison of the survival rates between standard and extended resection of pancreatic head cancer, no significant survival benefit was demonstrated from the prospective reports. PPPD may be superior to standard PD in respect to nutrition and quality of life without any deleterious effect upon long term survival or tumor recurrence. New surgical treatment modalities including modified extended pancreatectomy, neoadjuvant chemotherapy, and radical antegrade modular distal pancreatectomy have been tried to improve the patients' survival. However, early diagnosis and treatment remain as key factors for the cure of pancreatic cancer irrespective of various surgical trials.

OBJECTIVETo review the outcomes of living-related liver transplantation (LRLT) in treating 3 cases of cavernous transformation of portal vein (CTPV) with severe portal hypertension.

METHODSThree children (two boys and one girl) were presented to our hospital with recurring esophageal variceal bleeding, decompensating ascites, splenomegaly and refractory anemia. CTPV was confirmed by intravenous computed tomographic portography using a helical computed tomography scanner and 3-dimensional image reconstruction. LRLT were performed in these 3 patients from July 2006 to January 2007. The evaluation of the outcomes was made by referring to their clinical features and laboratory and imaging examination findings.

RESULTSAlthough one patient died from early graft thrombosis, the other two patients showed excellent prognoses. They lived and stayed well during a follow-up period of 12-14 months. Following the transplantations, there had been no esophageal variceal hemorrhage, the ascites disappeared and the portal hypertension vanished. Their hemoglobin, blood platelets count, and serum albumin reached normal values.

CONCLUSIONLRLT is an effective procedure in treating CTPV with severe portal hypertension. The reconstruction of the portal vein is the difficult part of the LRLT procedure.

Few are familiar with the gluconeogenesis that occurs in the intestine under fasting or the influence of insulin. Recently, however, studies that revealed the function of intestinal gluconeogenesis as a regulatory process for glucose homeostasis and appetite were described. The intestine produces about 25% of total endogenous glucose during fasting and regulates energy homeostasis through communication with the brain. Glucose produced via intestinal gluconeogenesis is delivered to portal vein where periportal neural system senses glucose and sends a signal to the brain to regulate appetite and glucose homeostasis. Moreover, studies uncovered that intestinal gluconeogenesis contributes to the rapid metabolic improvements induced by gastric bypass surgery.
