Abstract

Introduction

The use of a suction drain in Thyroid surgery is in common practice. This is done mainly to ‘prevent’ formation of haematomas and seromas on the Thyroid bed and subsequently to reduce complications and hospital stay.

Objective

The aim of this study is to determine the efficacy of routine drainage after Thyroid surgery.

Method

A randomized prospective control trial was conducted on 50 patients over a period of ten months. These patients were randomly allocated to drained and non-drained groups. The surgeon was informed of the group just before the closure of the wound. Post-operative ultrasound scan neck was done on second post-operative day by the Radiologist to assess the amount of fluid on the thyroid bed. Wound infection, seroma and heamatoma formation were assessed during the hospital stay and 1^st and 2^nd week after surgery. Post-operative pain was also assessed on postoperative day 2. The data were analysed using two sample T-test.

Results

Both groups were homogenous according to the age, size of the gland, type of the procedure performed and histopathological diagnosis. There was no significant collection of fluid on the Thyroid bed assessed by the USS scan on day 2 in the 2 groups (P = 0.1016). But the length of hospital stay was significantly reduced amongst the non-drained group (P = 0.0002). None of the patients in either group had post-operativeseroma orheamatoma and did not require reoperation for post-operative bleeding. No significant difference in post-operative pain was observed amongst two groups (P = 0.6818).
