STER for Esophageal Tumors

Certain tumors that grow within the wall of the esophagus can sometimes be removed endoscopically instead of surgically. Dr. Pavan Addala was the first surgeon in Andhra Pradesh to perform STER, in 2017.

Quick Summary

What Are Submucosal Esophageal Tumors

Submucosal tumors grow within the wall of the esophagus, beneath the lining, and many are benign (leiomyomas are the most common type). STER removes tumors from this deeper layer without cutting through the esophagus from outside.

Symptoms

Many cause no symptoms and are found incidentally. When symptoms occur: difficulty swallowing, a sensation of something stuck in the chest, chest discomfort.

Diagnosis

Diagnosis involves upper endoscopy with endoscopic ultrasound, which determines which layer the tumor arises from and its characteristics.

The STER Procedure

STER creates a tunnel within the esophageal wall, reaching the tumor from inside, removing it, and closing the tunnel entrance.

Recovery

Recovery is typically short, often one to two days of hospital observation, with a gradual return to normal eating.

Risks & Considerations

STER carries the general risks of any endoscopic procedure working within the esophageal wall, including bleeding and, rarely, perforation, though these are uncommon in experienced hands. Individual risk is discussed based on tumor size and location during evaluation.

Before You Decide

Because submucosal esophageal tumors are relatively uncommon and require specific expertise to evaluate accurately, a second opinion can help confirm the right course of action.

Frequently Asked Questions

Not usually. Most submucosal tumors are benign.

No. Small, asymptomatic tumors with reassuring features are sometimes monitored rather than removed.

No. Endoscopic, no external incision, generally shorter recovery than surgical removal.

Relatively uncommon; many are found incidentally rather than through symptoms.

Cost varies by tumor size and case complexity. Confirm coverage specifics with your insurer.
