Accidental ingestion of corrosive substances remains a major health hazard in children. Most infants and children who ingest caustic substances present with very few symptoms or signs. Approximately 40% of caustic substance ingestions result in esophageal injury, but the optimal management of caustic esophageal burns remains controversial, with different treatment modalities in use. The aim of this study was to compare the results of prophylactic early bougienage with dilatation that was begun after stricture development. We retrospectively analyzed the management of 125 pediatric cases of corrosive substance ingestion. For children seen primarily at our institution, initial management consisted of prompt endoscopy. Of 125 children admitted with a history of caustic substance ingestion, 54 were found to have esophageal burns, and 32 underwent treatment for stricture formation. Patients with severe injury were divided into two groups: In group A, consisting of 20 patients, prophylactic early dilatation had been done. In the eight patients in group B, dilatation had begun after stricture development. The strictures had resolved after 6 months of dilatation in patients initially treated with prophylactic early bougienage, whereas in patients in whom dilatation began after stricture development, stricture resolution did not occur for more than a year. The goal of initial treatment is to avoid stricture formation. Although early dilatations do not eliminate stricture formation completely, the stricture can resolve more easily with early bougienage.

The association between testicular tumors/nodules and congenital adrenal hyperplasia (CAH) has been recognized for many years. Tumors are considered to be an aberrant adrenal tissue that has descended with the testes and has become hyperplastic due to ACTH stimulation. The recommended treatment consists of increasing the glucocorticoid dose to suppress ACTH secretions. If the testicular size is not reduced after suppression therapy or a side effect of glucocorticoid dose is noted, surgical intervention should be considered. We diagnosed steroid unresponsive testicular tumors of the CAH in two patients who were treated by testicular sparing tumor enucleation. We believe that testis sparing surgery is the procedure of choice for all patients with testicular adrenal rest tumor, since it maximizes future fertility potential.

ED is the abnormal elevation of the diaphragm as a result of paralysis or aplasia of the muscular fibres. The abnormally elevated diaphragm may compress the ipsilateral lung, and with respiratory effort the mediastinum may shift towards the normal side. Therefore, diaphragmatic plication is performed to restore normal pulmonary parenchymal volume by replacing the diaphragm in its normal location. After plication, there was immediate remission of symptoms in most patients and decreasing symptoms were observed for a year in others. During follow-up, the location of the diaphragm was normal and no paradoxical movement was observed. Relapse of symptoms was not noted in patients with immobile diaphragms.

Anal canal duplication (ACD) is a very rare abnormality. Because of the high rate of malignant changes in anal canal duplications complete removal of the ACD is recommended. In the current study, simple mucosectomy for management of cases of ACD has been discussed. There was no complication and patients had good cosmetic results with a normal sphincter control. This technique is simple, safe, takes less time and achieves good anatomic appearance and functional results.

The results of our study showed that the majority of the patients have impaired anorectal motility. There were no significant differences in the results of the functional studies for the seven patients with symptoms of obstruction or constipation when compared with asymptomatic patients after surgery for HD.
