In the years 1963-1991 inclusive, 88 patients were operated on with a diagnosis of pulmonary hydatid disease. The cysts were intact in 69 and infected in 19 cases. It was possible to use a surgical technique that preserved the pulmonary parenchyma in 67 patients. In this technique, the cavity after removal of the mother membrane is left open and only the air leaks are sutured. Continuous postoperative drainage of the residual cavity and the ipsilateral hemithorax always resulted in complete inflation of the affected lung. Enucleation of the endocyst and extended resection of the sclerotic pulmonary parenchyma were performed in 15, enucleation and obliteration in three, lobectomy in two and Barrett's method was applicable in one patient. A bronchopleural fistula developed in 11 patients postoperatively and in four of these cases a second thoracotomy was necessary. Postoperative empyema developed in four cases. There were two postoperative deaths in the series. Eighty-six patients were symptom-free in the long-term postoperative follow-up. We conclude that in the surgical management of the disease it should not be necessary to obliterate the residual cavity with extensive suturing which always leads to extra fibrosis with loss of viable pulmonary parenchyma.

Five hundred and nineteen NaOH ingestion cases were admitted to our department between 1975 and 1994, and examined via esophagoscopy in the first 48 hours. Two hundred and forty-six patients in this series were diagnosed as severe burns endoscopically. This group of 246 patients were evaluated in a retrospective study to determine whether systemic steroid treatment had any place in preventing stricture formation following severe esophageal burns. Seventy-nine patients in this group were divided into three subgroups and they received methyl prednisolone parenterally in three different regimens. The control group consisted of 167 patients admitted between the years 1986 and 1994 who did not receive any form of steroid treatment. There were no statistically significant differences between the healing rates of the subgroups and the control group (p > 0.01). The authors concluded that systemic steroid treatment has no beneficial effect on esophageal wound healing following caustic esophageal burns.
