Abstract Background The aim of this study was to present a percutaneous transhepatic biliary puncture simulator that can be used without radiation exposure and that reflects the conventional anatomy of the biliary ducts and its vicinity structures. Methods An anatomically based model of the biliary tree was developed using a cord network fixed to a wooden frame. The skin, ribs, intercostal muscles, and right lower lobe pleura were simulated using foam sponge, plastic tubes, a polystyrene foam panel, and an air pad, respectively. For the puncture, we used a 20-G Chiba needle and a wire with distal double arches; these were used to troll a cord, simulating the successful puncture of a bile duct. A camera was also placed above the model to allow the trainees to train eye-hand coordination while viewing the image on a monitor in real time. The simulator was tested with 60 radiology residents to evaluate the confidence and skills transferability of the training model. Results After receiving an introduction of the system and 5 min of training under tutor surveillance, all participants were able to troll a cord of the biliary simulator by themselves in less than 4 min. Only one participant punctured the simulated pleura. The participants’ evaluations showed positive results, with increased user confidence and skills transferability after the training session. Conclusions This proposed simulator can be an effective tool to improve a trainee’s confidence and competence while achieving procedural and non-procedural interventional radiology skills related to the liver.

Background:Systemic sclerosis (SSc) is a chronic, connective tissue disease with an autoimmune pattern characterized by inflammation, fibrosis and microcirculation changes leading to internal organs malfunctions. The gastrointestinal tract (GIT) is affected in up to 90% of patients with SSc. Any part of the GIT from the mouth to the anus can be affected. There are few descriptive studies about SSc-related GIT involvement.Objectives:We aimed to characterize the GIT involvement in patients with SSc.Methods:This retrospective study included all patients from SSc cohort of our autoimmune diseases unit in a tertiary referral centre. All patients fulfilled SSc criteria proposed by the American College of Rheumatology. All subjects’ histories were evaluated. Laboratory and imaging results were obtained from the hospital files. Patients with digestive manifestations were compared with patients without GIT involvement. Chi2 and t-student were used, using the statistical package SPSS25.0.Results:83 subjects with SSc were included, 68 (81,9%) of them were women. The mean age at the onset of SSc was 62,1 ± 15,3 years (range 26-89) with a mean follow-up of 9,6 ± 7,4 years. 80,7% of patients had limited SSc, 12% diffuse SSc, 4.8% SSc sine scleroderma and 2,4% early SSc. Considering the immunological profile 12 (14,5%) had Scl70 antibodies, 49 (59%) anticentromere and 21 (25,3%) had ANA antibodies without specificity for anti-Scl70 or anticentromere. 37,3% patients had lung involvement, 20,5% scleroderma and 30,1% digital ulcers. 79,5% of SSc patients were treated with proton pump inhibitors or H2 blockers. 53 (63,9%) patients with SSc had GIT involvement. In 11 patients (20,7%) digestive involvement was diagnosed before SSc (mean 26,2 months). Esophageal involvement occurred in 83%, gastric involvement in 28,3%, intestine involvement in 24,5% and liver and biliary tree involvement in 26,4%. See table 1. No significant differences in age, sex, SSc subtype, autoantibody profile, lung involvement, skin disease, mortality and therapy were observed between patients with or without GIT manifestations. There were no deaths associated with GIT involvement. The most common pharmacologic therapy used was proton pump inhibitors (86,8%), domperidone (20,8%) and antibiotic rotation (17%).EsophagealGastricIntestinalLiver and biliary tree44/53 (83%)15/53 (28,3%)12/53 (24,5%)14/53 (26,4%)Esophageal motility disorder 8 (15,1%)Gastroparesis 6 (11,3%)Small bacterial overgrowth 7 (13,2%)Primary biliary cholangitis 9 (17%)Gastroesophageal reflux 40 (75,5%)Abdominal pain /nausea 10 (18,9%)Colonic inertia 1 (1,9%)Autoimmune hepatitis 3 (5,7%)Dysphagia 11 (20,8%)Subacute gastritis 7 (13,2%)Diarrhea 6 (11,3%)Cholestatic liver enzymes 11 (20,8%)Flatulence / abdominal discomfort 6 (11,3%)Cirrhosis 2 (3,8%)Conclusion:Almost two thirds of our cohort of SSc have symptomatic gastrointestinal disease. GIT manifestations are heterogeneous. Symptoms are non-specific and overlapping for a particular anatomical site. Esophagus is the most commonly affected. More than seventy-five per cent of patients experience symptoms of gastroesophageal reflux. We did not find differences among patients with and without SSc GIT disease. 17% of patients had a Reynold’s syndrome.References:[1]Alastal Y et al.

Endoscopic Fistulotomy

Endoscopic retrograde cholangiopancreatography (ERCP) is established as the method of choice to investigate the biliary tree when obstruction is suspected. On rare occasions, the papilla cannot be entered because of anatomical or pathological abnormalities. This report describes endoscopic fistulotomy or the suprapapillary punch that has been carried out at the Foothills Hospital in Calgary, Alberta, on 30 of 623 patients referred for ERCP for conditions causing obstruction of the common bile duct or suspected obstruction of the common bile duct. The following communication also describes the method of suprapapillary punch or endoscopic fistulotomy. Results have been excellent with only one complication, a minor attack of pancreatitis after the procedure. In summary, the suprapapillary punch or fistulotomy is a safe and useful method for entering the common bile duct when access by the usual method is impossible.
