Description of intervention(s) / exposure
: This is a cohort study which conducted from 02/08/2016 to 02/02/2019. Patients files and notes were reviewed in a retrospective manner. The entire participants had undergone open surgery in the form of total or subtotal thyroidectomy or lobectomy or hemithyroidectomy for benign thyroid disorders. And had been already admitted and discharged from the wards of Al-Imam Al-Hussein medical city hospital/University of Kerbala/Faculty of Medicine/Kerbala/Iraq. The selection of entire participants was based on certain criteria. Those participants had been classified into two categories; drain and no drain categories. Drain category had drain inserted following the operation, while the no-drain category did not have drain following the operation. A comparison between both categories was done with regards to the following variables ;(i) the occurrence of post operative heamatoma (ii) the post operative seroma formation. (iii) The duration and expenses of in-patient ward admission. Statistical analysis was done using Pearson Chi-square test, Independent sample t test and Mann-Whitney U Test
