O-Ring Protector in Prevention of SSIs in Laparoscopic Colorectal Surgery.

BACKGROUND

Surgical-site infections (SSIs) remain a serious complication of colorectal surgery, causing a significant financial burden to the health care system. The aim of this study is to investigate whether the use of an O-ring retractor can be effective in preventing the incidence of wound infections after elective laparoscopic colorectal surgery.

METHODS

A retrospective case-control study from January 2014 to June 2018 was performed. Data were analyzed from a retrospective colorectal database. SSI was defined according to criteria published by the European Centre for Disease Prevention and Control and analyzed as a primary outcome.

RESULTS

Three hundred twelve consecutive patients (n = 312) were enrolled in our study. Among them, 158 patients (Group A) in which an O-ring retractor device was used during surgery was compared with a control group of 154 patients (Group B) in which an O-ring retractor device was not used. Primary outcome was to determine SSIs rates among the 2 groups. No statistically differences were observed with regard to baseline characteristics between both groups. A total of 9 patients (5.69%) and 24 (15.58%) with SSIs were identified in Group A and B, respectively, and the difference was statistically significant (OR, 0.32; 95% CI, 0.14-0.72; = .0045). The median postoperative hospital stay length was 6.7 days in group A and 7.6 days in group B ( ≤ .05).

CONCLUSIONS

SSIs infections rates were significantly higher in patients in which an O-ring retractor device was not used. This study suggests that the use of a wound protector device can be considered for routine use in elective colorectal surgery.
