ABSTRACT IMPORTANCE Surgical site infection following stoma reversal (SR) poses a substantial burden to the patient and health care system. Its overall incidence is likely underreported and poorly characterized. Improving our understanding of surgical site infection following stoma reversal may help us identify methods to decrease this complication. OBJECTIVE To evaluate the incidence of surgical site infection (SSI) and identify predictors of SSI following SR. DESIGN A review of computerized hospital records on SR performed from January 1, 2005, until February 27, 2011. SETTING An integrated medical system at the Michael E. DeBakey Veterans Affairs Medical Center. PARTICIPANTS AND INTERVENTION All adults undergoing SR during the study period. MAIN OUTCOME MEASURES Rates of SSI and characteristics of patients with and without SSI were compared. A logistic regression model was developed to identify predictors of SSI. RESULTS One hundred twenty-eight patients underwent SR; 46 patients (36.0%) had an SSI. In comparison with no SSI, the infection was associated with seromas (17.4% vs 2.4%, P = .004), fascial dehiscence (15.2% vs 2.4%, P = .01), intensive care unit admission (34.8% vs 17.1%, P = .03), increased hospital length of stay (20 vs 9 days, P = .02), readmission (32.6% vs 13.4%, P = .01), delayed wound healing (91 vs 66 days, P = .02), and reoperation (32.6% vs 13.4%, P = .01). On multivariate analysis, history of fascial dehiscence (odds ratio, 16.9; 95% CI, 1.94-387), colostomy (5.07; 2.12-13.0), thicker subcutaneous fat (2.02; 1.33-3.21), and black race (0.35; 0.13-0.86) were associated with incisional SSI. There was no significant difference in patient satisfaction or functional status in late follow-up (1-73 months). CONCLUSIONS AND RELEVANCE Surgical site infection is common following SR and is associated with significant morbidity. Four factors are strongly associated with increased risk of SSI in SR: history of fascial dehiscence, thicker subcutaneous fat, colostomy, and white race. Patients with none of these risk factors had a 0% SSI risk; patients with all 4 risk factors had a 100% risk of SSI.

    ABSTRACT: The closure of a temporary stoma involves 2 different surgical procedures: the stoma reversal procedure and the abdominal wall reconstruction of the stoma site. The management of the abdominal wall has different areas that should be analyzed such us how to avoid surgical site infection (SSI), the technique to be used in case of a concomitant hernia at the stoma site or to prevent an incisional hernia in the future, how to deal with the incision when the stoma reversal procedure is performed by laparoscopy and how to close the skin at the stoma site. The aim of this paper is to analyze these aspects in relation to abdominal wall reconstruction during a stoma reversal procedure.

    ABSTRACT: Background/Aims: Surgical site infection (SSI) is a common complication of stoma reversal. Studies have suggested that different skin closures affect SSI rates. Our aim was to determine which skin closure technique following stoma reversal leads to the lowest rate of SSI. Methods: We conducted a retrospective review of all adult patients undergoing stoma reversal at a single institution (2005-2011) and compared the rate of SSI following four skin closure techniques: primary closure (PC), secondary closure (SC), loose PC (LPC), and circular closure (CC). Univariate analysis included χ(2) or Fisher's exact test and ANOVA or Kruskal-Wallis H test for categorical and continuous data, respectively. A multivariate logistic regression model was created to identify predictors of SSI. Results: One hundred and forty-six patients were identified: 40 (27%) PC, 68 (47%) SC, 20 (14%) LPC, and 18 (12%) CC. CC was less likely to have SSI (6%) compared to PC (43%), SC (16%), and LPC (15%; p < 0.01). Increasing body mass index was a predictor of SSI (odds ratio 1.11, 95% confidence interval 1.04-1.12, p < 0.01). CC was associated with the lowest odds of developing SSI [0.07 (0.01-0.63), p = 0.02]. Conclusions: SSI rate was the lowest for stomas that were closed with CC. © 2014 S. Karger AG, Basel.
