    Abstract:
    There are several reports on oesophageal strictures caused by alkali ingestion, but information on oesophageal strictures due to acid ingestion is scarce. Endoscopic dilatation, which has been found to be quite safe and effective in the treatment of benign oesophageal strictures of other aetiology, has also not been evaluated adequately in the treatment of these strictures. Over a period of 2 years, of 47 patients treated at this centre of benign oesophageal strictures, 17 (36.2%) patients had strictures following ingestion of corrosive agents. Thirteen patients had ingested acids and only four gave a history of alkali ingestion. The age range of these 13 patients was 14-50 years (mean = 25.5 years, s.d. = 2.6). The amount of acid ingested varied from 10 to 100 ml (median = 50 ml). The interval between acid ingestion and presentation to hospital ranged from 1 to 60 months (median = 2 months). Ten patients had multiple strictures, and the most common site of involvement was the upper third followed by the lower third of the oesophagus. Only five of these 13 patients had evidence of gastric involvement in the form of antral stricture (four) and hour glass deformity (one). Strictures were dilated using Eder-Puestow metal olives passed over a guide wire. The total number of sittings required to achieve adequate dilatation in this group ranged from 1 to 30 (median = 14). Most patients were managed successfully with dilatation (good response 63.6%, satisfactory response 18.2%). On follow-up, recurrence of dysphagia was seen in a high number of patients (66%), but this could be managed easily with repeat dilatation.(ABSTRACT TRUNCATED AT 250 WORDS)
