Abstract: Esophageal scar stenosis following chemical burns is a common and complex clinical issue. According to the Zargar classification, approximately 90% of patients with third-degree burns and 15%~30% of those with second-degree burns will develop esophageal or pyloric stenosis. Personalized treatment strategies tailored to the specifics of esophageal stenosis are particularly important.This review focuses on the selection of anastomotic sites during esophageal reconstruction following chemical burns and summarizes perioperative evaluations and timing of surgery. Overall, the treatment strategy for esophageal scar stenosis emphasizes personalized medicine, taking into account the characteristics of the stenosis and carefully selecting the most suitable surgical approach to achieve optimal therapeutic outcomes.
