Endoscopic management is challenging given the inability to directly access the lumen to allow for dilation. We present a case of esophageal reconstitution using an endoscopic rendezvous technique.
Case Description/
Methods: A 27-year-old man with a history of intellectual disability and refractory peptic stricture status post gastrostomy tube placement presented for EGD. On exam, he was not tolerating any secretions. EGD showed a dilated and fluid-filled esophagus with a completely closed-off stenosis in the distal esophagus, preventing passage of a guidewire. A pediatric endoscope was advanced through the gastrostomy tract and was also unable to identify the lumen on the distal end of the stenosis. The case was discussed with Cardiothoracic Surgery, who felt that the patient was a poor surgical candidate. The decision was made to manage the obstruction endoscopically using a rendezvous technique. An adult gastroscope was passed through the mouth to the level of the closed-off stenosis. A pediatric endoscope was passed through the patient's gastrostomy tract to allow for direct visualization from the distal esophagus. The two endoscopes were lined up on fluoroscopy. Under endoscopic and fluoroscopic guidance, the stiff end of a long 0.035-inch guidewire was passed through the gastroscope and used to puncture through the esophageal mucosa in the direction of the pediatric endoscope and the gastric lumen. The guidewire successfully passed into the stomach. The stenosis was dilated with a 10 mm biliary balloon dilator. Given the patient’s intellectual disability, nasogastric tube placement was not an option due to the risk of tube removal prior to mature tract formation. Therefore, the decision was made to place a metal biliary stent to maintain luminal patency. A 10 mm by 10 cm fully covered metal biliary stent equipped with anti-migration flaps was placed under endoscopic and fluoroscopic guidance. Endoscopic suturing was performed to further secure the stent in place with plans to upsize in 6-8 weeks after tract maturation. Discussion: For patients with refractory peptic strictures that progress to complete obstruction, surgical evaluation may be necessary. However, for non-surgical candidates with a pre-existing gastrostomy tract, endoscopic management with rendezvous technique offers a viable option for palliation.
