Percutaneous Balloon Dilatation for Hepaticojejunostomy Stricture Following Paediatric Liver Transplantation: Long-Term Results of an Institutional "Three-Session" Protocol.

Purpose: The aim of this study was to report the long-term results of an institutional protocol of percutaneous biliary balloon dilatation (PBBD) on paediatric patients with benign anastomotic stricture after liver transplantation. As a secondary objective, we evaluated risk factors associated with post-treatment re-stricture.

Materials And Methods: Fourteen paediatric, post-liver transplant patients with benign anastomotic stricture of Roux-en-Y hepaticojejunostomy were included.

Impact of Cholestasis on the Sensitivity of Percutaneous Transluminal Forceps Biopsy in 93 Patients with Suspected Malignant Biliary Stricture.

Purpose: The aim of this study was to determine the effect of hyperbilirubinemia in the sensitivity of percutaneous transluminal forceps biopsy (PTFB) in patients with suspected malignant biliary stricture.

Materials And Methods: Ninety-three patients with suspicion of malignant biliary stricture underwent percutaneous transhepatic cholangiography followed by PTFB. Sensitivity, specificity and predictive values were analysed based on the presence or absence of hyperbilirubinemia, defined as total bilirubin equal to, or higher than 5 mg/dL.

Fluoroscopy and endoscopy-guided transanastomotic rendezvous: a novel technique for recanalization of a completely obstructed colorectal anastomosis.

Background: Colorectal anastomotic stricture is a frequent complication that may affect up to 30% of patients. However, a complete obstruction is rare. Endoscopic balloon dilation is the first-line therapy, but it invariably requires being able to cross the stricture with the dilation device.

Early pancreatic cancer in IgG4-related pancreatic mass: A case report.

Background: IgG4-related disease can manifest diversely, including autoimmune pancreatitis and IgG4-related cholangiopathy. We are reporting a very unusual cause of pancreatic cancer triggered in a previously unknown IgG4-related disease.

Case Summary: A 75-year-old man was diagnosed with a 43 mm × 33 mm pancreatic head tumor after consulting for abdominal pain and jaundice.

Percutaneous Patency Recovery and Biodegradable Stent Placement in a Totally Occluded Hepaticojejunostomy After Paediatric Living Donor Liver Transplantation.

Biliary complications after living donor liver transplantation (LDLT) cause severe morbidity and mortality, with biliary anastomotic stricture being the most common form of presentation. Surgical revision is risky, and it is avoided whenever possible. When a Roux-en-Y hepaticojejunostomy (RYHJ) is used for bilioenteric reconstruction, endoscopic approach is more difficult, if not impracticable.

Risk factors and outcomes of pyogenic liver abscess in adult liver recipients: a matched case-control study.

Background: Adult liver recipients (ALR) differ from the general population with pyogenic liver abscess (PLA) as they exhibit: reconstructed biliary anatomy, recurrent hospitalizations, poor clinical condition and are subjected to immunosuppression. The aim of this study was to identify risk factors associated with PLA in ALR and to analyze the management experience of these patients.

Methods: Between 1996 and 2016, 879 adult patients underwent liver transplantation (LT), 26 of whom developed PLA.

Percutaneous Biliary Balloon Dilation: Impact of an Institutional Three-Session Protocol on Patients with Benign Anastomotic Strictures of Hepatojejunostomy.

Background: Percutaneous biliary balloon dilation (PBBD) stands as a safe, useful, and inexpensive treatment procedure performed on patients with benign anastomotic stricture of Roux-en-Y hepatojejunostomy (BASH). However, the optimal mode of application is still under discussion.

Methods: A retrospective cohort study was conducted including patients admitted between 2008 and 2015 with diagnosis of BASH.

Skin fibroblasts from patients with type 1 diabetes (T1D) can be chemically transdifferentiated into insulin-expressing clusters: a transgene-free approach.

The conversion of differentiated cells into insulin-producing cells is a promising approach for the autologous replacement of pancreatic cells in patients with type 1 diabetes (T1D). At present, cellular reprogramming strategies encompass ethical problems, epigenetic failure or teratoma formation, which has prompted the development of new approaches. Here, we report a novel technique for the conversion of skin fibroblasts from T1D patients into insulin-expressing clusters using only drug-based induction.

[Cell therapy for diabetes mellitus: beyond stem cells].

Type 1 diabetes is an autoimmune disease of unknown etiology characterized by destruction of pancreatic beta cells, leading to absolute insulin deficiency. Standard therapy includes the use of exogenous insulin. However, due to the difficulty to achieve a tight metabolic control, a number of patients will present severe complications, including vascular, renal and ophthalmologic disease.

Effect of the embolization of completely unpurified islets on portal vein pressure and hepatic biochemistry in clinical practice.

Here we report on the impact of completely unpurified islet transplantation on the portal vein pressure (PVP) and the hepatic biochemistry in the peritransplant period and on follow-up. Type I diabetic patients underwent simultaneous kidney and islet transplantation. Islets were not purified from the acinar tissue to prevent loss of endocrine mass.
