Mild to moderate stricture was developed after ESD for EGC abutting the pyloric ring, but the patient had no symptoms. Balloon dilatation is not required.

2. Treatment of gastric stricture

When the patient have symptoms of obstruction, single or multiple endoscopic balloon dilatations are required.

Two small EGCs are found in the pyloric ring. Two ESDs were successfully performed in a single session. Because of the obstruction symptoms, TTS dilatation was done. After the dilatation, there was no more obstructive symptoms. There was no recurrence until now (7 years after the procedure).

4. Prevention of esophageal stricture after ESD

After esophageal ESD, stricture is quite common. When symptoms are mild and intermittent, endoscopic treatment is not recommended. When obstuction symptom is moderate to sever, TTS balloon dilatation is usually required. In cases with circumferential ESD, preemptive treatments, as scheduled endoscotpic dilatation, triamcinolone injection, and oral prednisolone, have been tried. Currently, some authors recommended prophylatic therapy (link). Please refer to the recent review (Isomoto, 2013) for further information.
