Generally speaking, one to three dilations are enough to relieve dysphagia. Few patients require additional sessions. Complex strictures are usually longer (>2 cm), angulated, irregular, or have a severely narrowed diameter.
Gastrostenosis was originally treated by surgery, and balloon dilatation was used in 1982. Dilation is suitable for esophageal stenosis, benign pyloric obstruction, anastomotic stenosis after upper gastrointestinal anastomosis. Complications are generally rare. The more serious complication is gastrointestinal perforation. Local mucosal bleeding and edema may occur after balloon expansion, which can be relieved within a few days.

After the dilation is done, you will probably be observed for a short time and then back to normal life. You are allowed to drink when the anesthetic no longer makes numbness to your throat, unless your doctor has other instructions.
After esophageal dilation surgery, you'd better stay in bed, fast for two hours after surgery to avoid coughing, drink a small amount of warm water after two hours, observe whether there is chest pain and abdominal pain to determine whether there is pneumothorax and digestive tract perforation. Then you can gradually have high-sugar, high-protein, low-vitamin and no residue liquid diet. Observe your condition closely. Monitor blood pressure and breathing.
