Background:
The skin is closed in open appendectomy traditionally with few interrupted nonabsorbable sutures. The use of this old method is based on a suggestion that this technique decreases wound infections. In pediatric surgery, skin closure with running intradermal absorbable sutures has been found to be as safe as nonabsorbable sutures, even in complicated cases. Our purpose was to compare the safety of classic interrupted nonabsorbable skin closure to continuous intradermal absorbable sutures in appendectomy wounds in adult patients.
Methods:
A total of 206 adult patients with clinically suspected appendicitis were allocated to the study and prospectively randomized into two groups of wound closure: the interrupted nonabsorbable (NA) suture and the intradermal continuous absorbable (A) suture group. Primary wound healing was controlled on the first postoperative day, at 1 week clinically and after 2 weeks by means of a telephone interview. Follow-up data were obtained from 185 patients (90 in group NA and 95 in group A).
Results:
Continuous absorbable intradermal suturing was as safe as nonabsorbable sutures in regard to wound infections.
Conclusion:
Continuous, absorbable sutures can be used safely even in complicated appendicectomies without increasing the risk of wound infection. Considering the benefits of absorbable suturing, we recommend this method in all open appendectomies.
