Endoscopy is an effective technique for determining the presence of esophageal and gastric damage and to avoid unnecessary treatment in patients with no or mild injury.

Short-segment esophageal strictures, improvement of food intake capacity, and increase in intervals of dilation sessions are good patient indicators. We suggest that esophageal balloon dilatation is a safe and effective method of treatment in caustic esophageal strictures and recommend that balloon dilation program be performed for at least 2 years before deciding that dilation has failed and preferring other treatment modalities which have higher risk of complications.

Treatment of a perianal abscess either through incision and drainage with antibiotics or through antibiotics alone resulted in a high rate (85%) of fistula formation. Fistula-in-ano can be treated either by fistulotomy or by fistulectomy, both of which are associated with a reasonable chance of recurrence of fistula-in-ano formation. We obtained good results in our patients through surgical approach (fistulotomy or fistulectomy), for fistula-in-ano formed following treatment of perianal abscess.

Urinary NGAL levels may be used as a noninvasive diagnostic marker for predicting renal scarring in reflux nephropathy.

Although endoscopic balloon dilatation for benign PS in adults is a generally accepted method of treatment, there is less experience with endoscopic balloon dilatation for PS in children. PS due to benign disorders can be effectively and successfully treated through endoscopic balloon dilatation in suitable patients. In patients with successful pyloric balloon dilatation, surgery can be avoided.
