Evaluation of thoracic inlet view plain radiograph in the management of patients with goitre
Abstract
Background: Thoracic inlet view radiograph is an investigation for assessing patients with goitre in many centres in the sub-Saharan-
region. However, there is paucity of information on its usefulness in the diagnosis of retrosternal goitre (RSG) and in planning for thyroidectomy.
Method: A review of patients with goitre managed in the Division of Endocrine Surgery, University College Hospital, Ibadan, Nigeria, between 2002 and 2014 was done. Data were obtained from Operating Theatre Log and electronic data archive of the Division. Clinical RSG (CRSG) was taken as a gland that the examining fingers could not get below its lower margin and Radiological RSG (RRSG) on thoracic inlet view was any extension of the thyroid gland beyond the thoracic inlet. Intra-operatively, if any part of the gland extends beyond the thoracic inlet it was considered as an RSG.
Results: 221 (96.5%) of the 229 patients who had thoracic inlet plain radiograph were included in this study. The Male to Female ratio was 1:5.5. WHO grade III goitre was seen in 56.1% of the patients and 43.9% had grade II goitre. The CRSG, RRSG and Intra-operative RSG were seen in 7.7%, 16.7% and 17.6% respectively. The specificity and sensitivity of clinical examination in determining RSG was 88.7% and 94.1% and that of Thoracic inlet radiograph was 97.8% and 94.6% respectively.
Conclusion: It is a useful study for screening patients with goitre for retrosternal extension, however it could not be used to determine the need for extra-cervical surgical access during thyroidectomy.
