Experience with wound complications after surgery for sacral tumors

[摘要] PurposeThe aim of this article is to summarize our experience in treating sacral wound complications after sacrectomy. We focus, in particular, on factors associated with wound complications, including surgical site infection (SSI) and wound dehiscence.MethodsThe definition of SSI devised by Horgan et al. was applied. Wound dehiscence was defined as a wound showing breakdown in the absence of clinical signs meeting the diagnostic standard for SSI. Between September 1997 and August 2009, 387 patients with a sacral tumor underwent sacrectomy performed by the same team of surgeons and were followed up for ≥12 months. Potential risk factors were evaluated for univariate associations with SSI and wound complications. Multivariable conditional logistic regression was used to identify the combined effects of several risk factors.ResultsOf the 387 wounds studied, 274 healed uneventfully, and 113 (29.2 %) broke down because of infection or dehiscence. Fifty-one (13.2 %) patients developed a postoperative SSI, and 62 (16.0 %) patients developed wound dehiscence. Gram-negative bacteria grew in 45 cultures (91.8 %) and included 38 cases of Escherichia coli. Previous radiation, rectum rupture, longer duration of surgery, and cerebrospinal fluid leakage were significantly associated with increased likelihood of developing an SSI. Previous radiation, rectum rupture, age <40 years, history of diabetes mellitus, maximum tumor diameter ≥10 cm, and instrumentation used were risk factors for wound complications.ConclusionsThe incidence of wound complications is not so high at a musculoskeletal tumor center with surgeons experienced in treating sacral tumors. Controlling for these risk factors when possible may improve clinical outcomes...
