Abstract
BACKGROUND
Surgical site infection (SSI) is a common complication of gastrointestinal surgery. Because retention suture is known to prevent abdominal wound dehiscence, it is only considered indicated in high-risk patients. At present, there are no clear indications for retention suture. The purpose of this study was to analyze the effect of prophylactic retention suture and to determine what situations indicate prophylactic retention suture against SSI.
MATERIAL AND METHODS
Between January 2014 and January 2016, 135 patients who underwent midline laparotomy in our hospital were analyzed. Inclusion criteria for this study were patients with American Society Anesthesiologists' physical status classification system (ASA-PS score) ≥ 3 or emergent surgery.
RESULTS
Of the 135 patients, 30 (22.2%) received prophylactic retention suture. Diabetes mellitus, surgical wound classification, large incision, and retention suture were associated with SSI in multivariate analysis. In subgroup analysis, SSI risk factors were analyzed in each surgical wound classification. Only in surgical wound classification class II and III did retention suture significantly reduce the risk of SSI (odds ratio = 0.100 [0.012-0.837], P = 0.034). In class IV, however, half the patients developed SSI, regardless of retention suture. Table 3 summarizes the results of the subgroup analysis.
CONCLUSIONS
The present data suggest that prophylactic retention suture reduces SSI for surgical wound classification class II or III. For class IV operations, however, other methods to prevent SSI are necessary.
