SUBMUCOSAL TUNNELING ENDOSCOPIC BIOPSY FOR MANAGEMENT OF UNKNOWN ESOPHAGEAL STENOSIS

Video Transcription

Video Summary

In this video, a 48-year-old man with a history of lung cancer is admitted to the hospital with severe dysphagia. Despite previous treatments, including surgery, chemotherapy, and radiation, the cancer has recurred and metastasized. The patient had undergone esophageal dilation at a local hospital but saw no improvement. Further examinations revealed inflammatory lesions in the mid-thoracic esophagus and mediastinal lymphadenitis. To determine the cause and plan treatment, an endoscopy ultrasound examination was conducted, which showed thinning of the muscular layer. After discussing the findings, a semicircular tunneling endoscopy biopsy was performed, including muscle biopsy. Steps included mucosal incision, side mucosal channeling, full thickness myotomy, muscle biopsy, and mucosal closure with endoclips. No evidence of cancer recurrency or metastasis was found.
