Comparison of scar with polypropylene and polyglactin 910 in thyroid incisions

ABSTRACT

To compare quality of scar after subcuticular stitches between Polypropylene [Prolene], a non-absorbable suture, with Polyglactin 910 [Vicryl], an absorbable suture after thyroid surgery. Randomized controlled trail [RCT]. Department of Surgery Combined Military Hospital and Military Hospital Rawalpindi from 1 Jan 2007 to 31 Dec 2007. Sixty patients undergoing elective thyroid surgery were included and randomly divided into two groups using random number tables. Informed written consent was obtained from each patient. The neck wound was closed by subcuticular suturing technique and the suture material was used according to the sampling technique. The patients were followed up in OPD on 10[th] post operative day and twelve weeks after surgery for the quality of scar. After 10 days, 1 patient in each of the Polypropylene group [3.3%] and Polyglactin 910 group [3.3%] had a bad scar [p = 1.000]. After twelve weeks of surgery, 2 patients in the Polypropylene group [6.7%] and 3 patients in the Polyglactin 910 group [10.0%] had bad scars [p = 1.000]. There is no significant difference between the frequency of bad scar formation in the Polypropylene and Polyglactin 910 group. It is thus recommended that absorbable Polyglactin 910 sutures should be used for wound closure after thyroid surgery as it does not require suture removal and thus prevents patient anxiety and discomfort and also saves surgeon and staff's time
