Post-oesophagectomy gastric conduit outlet obstruction following caustic ingestion, endoscopic management using a SX-ELLA biodegradable stent: A case report

BACKGROUND: Benign oesophageal strictures secondary to caustic ingestion are rare and difficult to manage. They often present with symptoms such as chest pain, dysphagia and vomiting. Surgical resection is often not justified in majority of these cases who later presents with recurrent benign stricture. CASE SUMMARY: We present a unique case of a patient who presented with post-oesophagectomy gastric conduit outlet obstruction (POGO) secondary to caustic ingestion. Our patient had already undergone two stage oesophagectomy with pyloroplasty for operable oesophageal cancer with curative intent 5 years prior. This is a distinctive case, where a successful deployment of a SX-ELLA biodegradable (BD) stent (019-10A-28/23/28-080) after failed dilatations. We have briefly reviewed literature with regards to the role BD stents in patients with recurrent benign stricture and discussed management dilemma. CONCLUSION: We recommend the attending gastroenterologist should bear the usefulness of BD stents in the management of refractory POGO after oesophagectomy.
