Protocol for acquisition of images and measurement of transabdominal ultrasound pancreatic two-dimensional shear wave elastography (2D-SWE). / Protocolo de adquisición de imágenes y medición de la elasticidad pancreática mediante elastografía por onda de cizallamiento bidimensional (2D-SWE) transabdominal.

INTRODUCTION: Transabdominal ultrasound (TU) pancreatic 2D-SWE elastography is a developing technique that needs to be protocolized. OBJECTIVES: Establish a protocol for image acquisition and measurement of TU pancreatic - 2D-SWE elastography and estimate the minimum number of measurements to be performed. MATERIALS AND METHODS: Ten measurements of pancreatic elasticity were taken in healthy volunteers using TU-2D-SWE, following a strict protocol for image acquisition and measurement. RESULTS: The 70% of the participants were women, with an average age, weight, and BMI of 49.5±15.7 years, 65.9±11.9kg, and 24.5±4.2kg/m2, respectively. Measurements were taken from the body (70%), tail (16.7%), and pancreatic head (13.3%). The median mean velocity and elasticity were 1.46±0.25cm/sec and 6.46±2.87KPa, respectively. The ROI depth was 4.12±1cm and the SP-ROI distance was 5.2mm on average. There were no statistically significant differences between the 10 measurements. The reliability analysis of the measurements showed high internal consistency and repeatability. Taking 5-6 measurements ensured high concordance with the ten reference measurements. The measurements were significantly lower when the SP-ROI values were intermediate (0.3-0.6cm). The measurement accuracy was higher when performed at a depth less than 4.8cm. CONCLUSION: To measure pancreatic elasticity using TU-2D-SWE, we propose a strict protocol for image acquisition and measurement, taking a minimum of 5 measurements in the best visualized and accessible pancreatic portion, and preferably at a depth of less than 4.8cm.

Double major papilla: diagnostic challenge of an unusual anatomical variant.

We report the endoscopic finding of a double papilla of Vater in a patient presenting choledocholithiasis who underwent endoscopic retrograde cholangiopancreatography (ERCP). The images showed the presence of two perfectly delimited papillary orifices, 1cm apart from each other. After cannulation of each orifice, we observed the Wirsung and the common bile duct (CBD) as completely independent ducts. Given the diagnostic challenge posed by this entity and the importance of differentiating it from a bilioenteric fistula, we believe it is worth knowing about it in order to manage it properly and to minimize secondary risks during the exploration.

Duodenal pyogenic granuloma: An unusual cause of chronic anemia.

We present the endoscopic finding of a juxtapapillary duodenal pyogenic granuloma in a patient under study for chronic recurrent anemia. The images show the presence of an enlarged papilla, with an exophytic growth of erythematous and friable tissue at its lower border. Although this is a very rare entity, it is necessary to take it into account in the differential diagnosis of refractory anemia because there is an effective endoscopic treatment for it.

Management of betablocked patients after sustained virological response in hepatitis C cirrhosis.

BACKGROUND: Current guidelines do not address the post-sustained virological response management of patients with baseline hepatitis C virus (HCV) cirrhosis and oesophageal varices taking betablockers as primary or secondary prophylaxis of variceal bleeding. We hypothesized that in some of these patients portal hypertension drops below the bleeding threshold after sustained virological response, making definitive discontinuation of the betablockers a safe option. AIM: To assess the evolution of portal hypertension, associated factors, non-invasive assessment, and risk of stopping betablockers in this population. METHODS: Inclusion criteria were age > 18 years, HCV cirrhosis (diagnosed by liver biopsy or transient elastography > 14 kPa), sustained virological response after direct-acting antivirals, and baseline oesophageal varices under stable, long-term treatment with betablockers as primary or secondary bleeding prophylaxis. Main exclusion criteria were prehepatic portal hypertension, isolated gastric varices, and concomitant liver disease. Blood tests, transient elastography, and upper gastrointestinal endoscopy were performed. Hepatic venous pressure gradient (HVPG) was measured five days after stopping betablockers. Betablockers could be stopped permanently if gradient was < 12 mmHg, at the discretion of the attending physician. RESULTS: Sample comprised 33 patients under treatment with propranolol or carvedilol: median age 64 years, men 54.5%, median Model for End-Stage Liver Disease (MELD) score 9, Child-Pugh score A 77%, median platelets 77.000 × 103/µL, median albumin 3.9 g/dL, median baseline transient elastography 24.8 kPa, 88% of patients received primary prophylaxis. Median time from end of antivirals to gradient was 67 wk. Venous pressure gradient was < 12 mmHg in 13 patients (39.4%). In univariate analysis the only associated factor was a MELD score decrease from baseline. On endoscopy, variceal size regressed in 19/27 patients (70%), although gradient was ≥ 12 mmHg in 12/19 patients. The elastography area under receiver operating characteristic for HVPG ≥ 12 mmHg was 0.62. Betablockers were stopped permanently in 10/13 patients with gradient < 12 mmHg, with no bleeding episodes after a median follow-up of 68 wk. CONCLUSION: Portal hypertension dropped below the bleeding threshold in 39% of patients more than one year after antiviral treatment. Endoscopy and transient elastography are inaccurate for reliable detection of this change. Stopping betablockers permanently seems uneventful in patients with a gradient < 12 mmHg.

Pyogenic granuloma of the duodenum as an unusual cause of gastrointestinal bleeding

Pyogenic granuloma of the duodenum as an unusual cause of gastrointestinal bleeding.

Pyogenic granulomas are lobular capillary hemangiomas, usually found on skin and oral mucosa. To date, few cases of pyogenic granuloma of the gastrointestinal tract have been reported, being duodenal involvement extremely rare. We report the case of a patient with a history of long-standing iron deficiency anemia where the endoscopy revealed an oozing redish semipedunculated polypoid lesion in the duodenum with a biopsy specimen consistent with a pyogenic granuloma. The lesion was removed by endoscopic resection, and during the follow-up hemoglobin level was maintained.

Acute psychotic episode secondary to Helicobacter pylori eradication treatment.

The side effects of Helicobacter pylori (H. pylori) eradication treatment are few, usually in the form of gastrointestinal or allergic complaints. However, occasionally, some antibiotics including clarithromycin, included in the classic eradication regimen, may result in reversible psychosis, a condition called "antibiomania" or "Hoigne syndrome".

Ultrasound-guided percutaneous drainage and sclerotherapy in a patient with isolated autosomal dominant polycystic liver disease.

Isolated polycystic liver disease (IPLD) is a rare genetic condition characterized by the presence of multiple liver cysts with no association with polycystic kidney disease. Most patients are asymptomatic and acute complications (cyst torsion, bleeding, infection) are uncommon.Imaging techniques, including abdominal ultrasounds, computerized axial tomography, and magnetic resonance imaging, represent a vital diagnostic modality. They are also useful for therapy support in this disease. Below we report a peculiar case of a female patient recentlydiagnosed with IPLD who, having received treatment with ultrasoundguided percutaneous drainage and sclerotherapy for a giant liver cyst, showed symptom and laboratory improvement.

Drenaje percutáneo y escleroterapia guiada por ecografía en paciente con poliquistosis hepática aislada autosómica dominante / Ultrasound-guided percutaneous drainage and sclerotherapy in a patient with isolated autosomal dominant polycystic liver disease

La enfermedad hepática poliquística aislada (EHPA), es una rara entidad genética que se caracteriza por la presencia de múltiples quistes hepáticos, sin estar asociada a la poliquistosis renal. La mayoría de los pacientes son asintomáticos, y son infrecuentes las complicaciones agudas (torsión quística, hemorragia e infecciones). Las técnicas de imagen, como la ecografía abdominal, tomografía axial computarizada y resonancia magnética, son un método diagnóstico fundamental. Además, son útiles como apoyo terapéutico en esta enfermedad. A continuación les presentamos un caso clínico peculiar de una paciente recientemente diagnosticada de enfermedad hepática poliquística aislada, quien tras recibir un tratamiento con drenaje percutáneo de un quiste hepático gigante y escleroterapia guiada por ecografía, presentó mejoría sintomática y analítica
