Two double-pigtail stents were placed across the LAMS to relieve the obstruction. Endoscopic placement of a lumen-apposing metal stent (LAMS) is a novel means of managing patients with malignant gastric outlet obstruction (GOO), particularly those with prohibitive surgical risk factors. However, long-term data on endoscopic gastrojejunal LAMSs are lacking, and mechanical obstruction may still occur from benign processes. In this video (Video 1, available online at www.giejournal.org), we describe a novel case in which double-pigtail stents were used to manage an obstructed LAMS due to occlusion of the distal flange of the LAMS by the contralateral jejunal wall. A 71-year-old woman with locally advanced pancreatic adenocarcinoma was referred for GOO. Her history was notable for prior placement of a gastrojejunal LAMS for management of malignant GOO secondary to infiltration of the duodenum by pancreatic adenocarcinoma. Upper endoscopy revealed recurrent GOO (Fig. 1A and B) at the distal flange of the LAMS owing to occlusion by the contralateral wall of the jejunum. A 0.035-inch guidewire (Dreamwire; Boston Scientific Corporation, Natick, Mass, USA) was coiled into the afferent and efferent jejunal limbs (Fig. 1C and D). To keep the contralateral jejunal wall away from the LAMS, 2 double-pigtail stents (Advanix Biliary Stents; Boston Scientific Corporation) were placed, one into the afferent jejunal limb across the LAMS and the other into the efferent jejunal limb (Fig. 1E and F). A single pigtail may provide sufficient ability to prevent jejunal wall obstruction on the distal end of the LAMS, but using 2 pigtails (1 in the afferent limb and 1 in the efferent limb) ensures patent drainage.1Chen Y.I.

In this case, the double-pigtail stents allowed successful treatment of a recurrent GOO. Prospective, randomized clinical trials are warranted to validate this procedure as treatment in patients with recurrent GOO.
