Battery acid burns of the upper gastro-intestinal tract
1Department of Otolaryngology, Groote Schuur Hospital, Cape Town, South Africa.
Abstract:
Strong acid ingestion produces distinctly different injuries from alkali burns. Alkali burns are well described but the lack of literature on the diagnosis and management of acid burns is apparent. This retrospective review of 18 patients with battery acid (30% sulphuric acid) ingestion showed no correlation between the severity of the symptomatology and the degree of injury. The quantity of acid needed to cause a significant upper GIT burn was more than 200 ml. Previous reports that acid spared the oesophagus due to rapid transit were disproved, since oesophageal involvement was found in 55% (10/18). Deep burns rather than circumferential burns resulted in stricture formation. The major injury site was the gastric antrum with 4 patients (23%) requiring surgical intervention to restore function.
