ObjectivesEndoscopic retrograde cholangiopancreatography (ERCP) represents the gold standard for jaundice palliation in patients with distal malignant biliary obstruction (DMBO). Biliary drainage using electrocautery lumen apposing metal stent (EC‐LAMS) is currently a well‐established procedure when ERCP fails. In a palliative setting the endoscopic ultrasound‐guided gallbladder drainage (EUS‐GBD) could represent an easy and valid option. We performed a prospective study with a new EC‐LAMS with the primary aim to assess the clinical success rate of EUS‐GBD as a first‐line approach to the palliation of DMBO.MethodsIn all, 37 consecutive patients undergoing EUS‐GBD with a new EC‐LAMS were prospectively enrolled. Clinical success was defined as bilirubin level decrease >15% within 24 h and >50% within 14 days after EC‐LAMS placement.ResultsThe mean age was 73.5 ± 10.8 years; there were 17 male patients (45.9%). EC‐LAMS placement was technically feasible in all patients (100%) and the clinical success rate was 100%. Four patients (10.8%) experienced adverse events, one bleeding, one food impaction, and two cystic duct obstructions because of disease progression. No stent‐related deaths were observed. The mean hospitalization was 7.7 ± 3.4 days. Median overall survival was 4 months (95% confidence interval 1–8).ConclusionEndoscopic ultrasound‐guided gallbladder drainage with the new EC‐LAMS is a valid option in palliative endoscopic biliary drainage as a first‐step approach in low survival patients with malignant jaundice unfit for surgery. A smaller diameter EC‐LAMS should be preferred, particularly if the drainage is performed through the stomach, to avoid potential food impaction, which could result in stent dysfunction.

Pancreatic adenocarcinoma is the most common malignancy of the pancreas; on rare occasions, metastatic tumors are present. Differentiating a primary neoplasm from a metastatic one is important for ensuring adequate treatment for the patient. We present a case of metastatic melanoma to the pancreas. A 60-year-old man presented with a history of weight loss, vague abdominal pain, jaundice, and pruritus. Laboratory tests showed increased total bilirubin, with a direct fraction predominance, as well as increased alkaline phosphatase and gamma glutamyl transferase. Imaging studies revealed a mass in the head of the pancreas. Endoscopic ultrasound (EUS)-guided fine needle biopsy was performed, and histologic examination confirmed the diagnosis of metastatic melanoma. This case report illustrates the invaluable use of EUS-guided tissue acquisition in the study of pancreatic solid lesions to obtain an accurate diagnosis. Melanomas should always be part of a differential diagnosis when evaluating patients with pancreatic masses.

Se hizo un estudio retrospectivo en el cual se revisaron los expedientes de 1135 pacientes sometidos a endoscopias digestivas diagnósticas y terapéuticas, en el período comprendido entreenero de 2016 y marzo de 2017. Los pacientes se organizaron por su: edad, género, clasificación de riesgo de la Sociedad Americana de Anestesiólogos, indicación para la endoscopia, y dosis utilizada de propofol. Se registraron los efectos adversos asociados al uso de Propofol, tales como: episodios de hipoxemia transitoria, complicaciones cardiopulmonares serias y muerte.
