Medical history was significant for critical alcohol consumption and an episode of acute pancreatitis >20 years ago. Transabdominal ultrasound and computed tomography indicated advanced calcified chronic pancreatitis with marked biliary dilation and minor pancreatic duct dilation. The patient underwent endoscopic-retrograde cholangiopancreatography (ERCP) revealing a complex tight and hard-to-cross biliary stricture, thus a 10-Fr biliary plastic stent was inserted. Pancreatic duct intervention was not entertained in the absence of pancreatic-type pain. Following this cholestasis parameters were significantly improved including normalization of bilirubin levels and the patient's weight stabilized under pancreatic enzyme substitution for fecal elastase-confirmed exocrine insufficiency. Given that an additional endoscopic ultrasound (EUS) did not clearly suggest malignancy over pancreatitis-related benign biliary stricture and the patient was a very poor surgical candidate, temporary metal stenting using a 60<span class="elsevierStyleHsp" style=""></span>×<span class="elsevierStyleHsp" style=""></span>10-mm fully-covered self-expanding metal stent (FCSEMS) was performed. Due to difficulties in transversing the stricture at index ERCP we opted for a “two-devices-in-one-channel”-approach for a guidewire-secured plastic-to-metal stent switch. First, the papilla with the indwelling 10-Fr double-pigtail plastic stent was visualized (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1A</a>) and a 0.035-in guidewire inserted alongside the stent by an ERCP cannula. (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1B</a>) Next, a grasper was inserted through the 4.2-mm working channel of the therapeutic duodenoscope next to the guidewire left in place and the most distal part of the plastic stent grasped (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1C</a>) and extracted through the scope (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1D</a>). Finally, the FCSEMS was inserted over the guidewire (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1E</a>) and deployed as per standard procedure. (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1F</a>) In addition, supplementary oral nutrition and pancreatic enzyme replacement was initiated.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><p id="par0010" class="elsevierStylePara elsevierViewall">Taken together, the “two-devices-in-one-channel” approach represents an easy-to-accomplish trick of the trade out of the interventional endoscopists toolbox to avoid troublesome re-cannulation manoeuvres in difficult strictures.</p><span id="sec0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0005">Financial disclosure</span><p id="par0020" class="elsevierStylePara elsevierViewall">The author discloses no financial relationships relevant to this publication.</p></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Conflict of interest</span><p id="par0025" class="elsevierStylePara elsevierViewall">The author states no conflict of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:2 [ 0 => array:2 [ "identificador" => "sec0005" "titulo" => "Financial disclosure" ] 1 => array:2 [ "identificador" => "sec0010" "titulo" => "Conflict of interest" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "multimedia" => array:1 [ 0 => array:7 [ "identificador" => "fig0005" "etiqueta" => "Figure 1" "tipo" => "MULTIMEDIAFIGURA" "mostrarFloat" => true "mostrarDisplay" => false "figura" => array:1 [ 0 => array:4 [ "imagen" => "gr1.jpeg" "Alto" => 873 "Ancho" => 1750 "Tamanyo" => 236663 ] ] "descripcion" => array:1 [ "en" => "<p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">(A) Duodenoscopic visualization of the indwelling 10-Fr biliary double pigtail plastic stent.
