Résumé
Background: The total goitre rate in Yemen declined by half after the country adopted universal salt iodisation in 1995. We investigated the recent epidemiology, pathology, and management of goitre so as to evaluate changes since the initiation of the salt iodisation programme. We also sought to determine the effect of new diagnostic tools in the preoperative work-up of surgically treated patients
Methods: Data were collected from the records of 667 patients with goitre seen in Kuwait University Hospital between 1997 and 2001
Results: Females constituted 92.5% [n=617] of the series. The mean age of all patients was 35.2 +/- 11.58 years [range, 13 to 90 years]. Most patients [93%] came from highland areas with an average altitude of 2000 to 2600 meters above sea level. The average duration since patients noticed swelling until the diagnosis was made was about 4 years. Multinodular bilateral swelling was the most common clinical finding [44.9%], while solitary nodules constituted the least common [17.4%]. The most common associated symptom was dyspnoea [20.5%]. The most common histopathological finding was nodular and colloid goitre [62.8%], while malignancy accounted for 17.7%. Subtotal thyroidectomy was the most frequent procedure, and the most common postoperative complication was hypocalcaemia
Conclusion: Goitre is a national problem in Yemen. The late presentation, which may be important in malignant transformation of the thyroid gland, makes surgery imperative. The salt iodisation programme has been associated with a decrease in the malignancy rate. Yemen is in great need of experienced cytologists and radiologists to increase the efficacy of fine needle aspiration cytology and ultrasonography in the diagnosis of thyroid lesions. Patients need to be educated about the importance of post-operative follow up
