TAPIA, CLAUDIO et al. Early detection of wound infection after appendectomy. Rev Chil Cir [online]. 2006, vol.58, n.3, pp. 181-186. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262006000300004.

Background: Wound infection is one of the most common complications of appendectomy. We devised a method for early detection of this complication. A piece of braid suture is left in the subcutaneous tissue (sentinel stitch) of the operative wound, is withdrawn 24 to 48 after the surgical procedure and cultured. Aim: To assess the usefulness of the sentinel stitch in the diagnosis of wound infections. Material and Methods: Forty six patients operated for a perforated acute appendicitis were studied. The cultures of the sentinel stitch were compared with the clinical evaluation of the operative wound, indicating the presence of infection. Results: Eleven patients had an operative wound infection. Ten of these had a positive culture of the sentinel stitch. The cultures were negative in 34 of 36 patients without wound infection. Therefore, the sensitivity and specificity of the sentinel stitch were 91 and 97% respectively. Conclusions: The sentinel stitch is a simple and effective method for the early detection of wound infections after appendectomy
