[The surgical management of tracheal stenosis]. / Manejo quirúrgico de las estenosis traqueales.

We analyzed 26 cases of tracheal stenosis treated (ET) surgically at the National Institute of Respiratory Diseases between March 1987 and June 1990. The surgical technique practiced was end-to-end anastomosis of the trachea (ATT). The most important cause of stenosis was oro-tracheal intubation (69.2 percent). Followed by tracheostomy, respiratory scleroma, thyroid carcinoma with tracheal invasion and neck trauma. We describe the treatment of the patients and discussed the results, which were satisfactory from the functional anatomical point of view in all patients except one who died of hepatic coma 2 weeks postoperatively. We conclude that end-to-end anastomosis of the trachea is the treatment of choice to tracheal stenosis.

[Effect of the treatment of hyperthyroidism on the course of exophthalmos]. / Influencia del tratamiento del hipertiroidismo en el curso del exoftalmos.

The exophthalmos evolution in hyperthyroid patients was investigated: twenty patients were randomly assigned to treatment with radioiodine (group I followed 2-162 months) and 20 to treatment with thyroidectomy (group II followed 2-158 months). There was no correlation of sex age and follow up with exophthalmos evolution. In group I, exophthalmos improved in one patient (5%), did not change in ten (50%) and worsened in nine (45%). In group II it got better in six (30%), did not change in seven (35%) and got worse in seven (35%). The differences between the two groups were not statistically significant (p greater than 0.05). The postsurgical thyroid gamma-gram with one mCi of I-131 in group II showed absence of thyroid tissue in nine patients (45%) and remainders of the gland in 11 (55%) and apparently this did not influence the post treatment evolution. The length of pretreatment evolution did not influence the evolution post treatment. In summary, there was no correlation between exophthalmos evolution and kind of treatment in Graves' disease.
