简要总结
The investigators intend to determine the role of Seprafilm, a popular anti-adhesive agent in minimising internal adhesion formation in the neck after thyroid surgery and therefore reduce swallowing discomfort experienced by patients after surgery.
详细描述
Thyroid surgery not only constitutes one of the main pillars in the treatment of thyroid cancers, but is also employed in the management of symptomatic goitres. Occasionally, it is mandated in patients with thyrotoxicosis refractory to medical therapy. While thyroid surgery can be performed with low risks such that patients rarely have to stay beyond three days in hospital, the track record of thyroid surgery is somewhat blemished by the unfortunate side effects associated with the neck scarring after thyroid surgery. Not uncommonly, patients experience discomfort in the neck region after thyroid surgery; in the extreme of cases, patients may even complain of a lifelong pulling sensation in the neck area during eating.
The anti-adhesive properties of Seprafilm are well established in animal studies and affirmed by clinical observations in abdominal surgeries that utilize this material. Thus, Seprafilm is routinely used in instances when a surgeon foresees a need to perform abdominal surgery on the same patient in future, or during the fashioning of a temporary stoma. The safety profile of Seprafilm in thyroidectomy has also been shown by a recent study conducted by a group of clinicians in Seoul.
We postulate that the application of Seprafilm to the surgical wound towards the end of a thyroidectomy significantly reduces internal adhesion formation in the neck region. By achieving this objective, we hope to improve patients' satisfaction with thyroid surgery in terms of ease of swallowing after surgery.

结局指标
主要结局
Cricoid elevation
时间窗: 1 to 14 days before the surgery, postop day 14 and 3 months postop
Trial candidates are to undergo videofluoroscopy to assess their swallowing and cricoid elevation is measured using ImageJ. * First measurement is 1 to 14 days before the surgery. * Second measurement is 14 days postop. * Third measurement is 3 months postop.
次要结局
- Hyoid elevation(1 to 14 days before the surgery, postop day 14 and 3 months postop)
- Crico-hyoid distance(1 to 14 days before the surgery, postop day 14 and 3 months postop)
- Videotaping measurement(1 to 14 days before the surgery, postop day 14 and 3 months postop)
