S352 Presidential Poster Award Light at the End of the Tunnel: Pipeline to the Jejunum

Introduction: Small intestinal strictures that are distal to the duodenum, particularly the jejunum, are uniquely complicated to manage. Adult endoscopes are often too short or too rigid to reach this region of the small bowel. Furthermore, duodenal stents are not flexible enough and are uncovered. In this case, we were able to place several esophageal stents in the proximal jejunum using a pediatric colonoscope that could not be placed previously. Case Description/Methods: A 56 year-old woman with hypertension, obstructive lung disease, and a prior ischemic stroke presented to the hospital for four days of postprandial emesis, abdominal distention, epigastric pain, and constipation. She previously underwent appendectomy and hysterectomy, and had no prior endoscopic studies. Computed tomography (CT) was performed demonstrating mural thickening of the distal duodenum and partial occlusion of the small bowel with regional lymphadenopathy, and a large left adrenal mass. Esophagogastroduodenoscopy (EGD) showed an intrinsic severe stenosis in the distal duodenum. After biopsies were taken, the tissue was found to be a primitive neuroectodermal tumor. Because of the presence of mesenteric adhesion and extensive stenosis, it was decided to correct the stricture endoscopically rather than with surgical intervention. Using a pediatric colonoscope and fluoroscopic guidance, three stents were placed sequentially and telescoping each other from the proximal jejunum to the distal duodenum: a fully covered 20 mm x 120 mm esophageal stent, a partially covered 18 mm x 97 mm esophageal stent, and a fully covered 20 mm x 60 mm esophageal stent (Figure). There were no immediate complications with the procedure and repeat imaging demonstrated luminal patency. Due to the expansion of the stents through a tight stricture, the abdominal pain and pressure was present despite no evidence of perforation on CT. Discussion: This demonstrates the feasibility of utilizing multiple esophageal stents to help relieve more distal gastrointestinal obstructions that were not feasible in the past. The covered esophageal stents are extremely useful when there is discontinuity in the lumen of the small bowel to keep the natural flow of food and help prevent surgical interventions.
