Management of Early-Stage Esophageal Adenocarcinoma by Endoscopic Spray Cryotherapy in the Setting of Portal Hypertension With Varices.

The use of endoscopic spray cryotherapy to manage pathological conditions of the esophagus has become increasingly common. This mucosal ablation technique is believed to carry a lower risk of bleeding than other modalities. A 71-year-old woman and a 64-year-old man with portal hypertension and varices were diagnosed with invasive esophageal adenocarcinoma during routine variceal surveillance. Staging by endoscopic ultrasound and computed tomography was uT1N0M0 in both patients. They each underwent mucosal ablation using liquid nitrogen cryosprays with no adverse events. Both cancers completely resolved with 2 treatments, and neither patient has shown recurrence of neoplasia during follow-up observations for up to 2 years.
