Risk Factors for Surgical Site Infection After Laparoscopic Colectomy: An NSQIP Database Analysis

Abstract Background Surgical site infection (SSI) is a common complication after colon surgery. This study aimed to evaluate risk factors for SSI and its types in laparoscopic colectomy patients using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. Materials and methods The NSQIP database was queried for patients undergoing laparoscopic colectomy from 2011 through 2017. Univariate analysis and multivariable logistic regression were used to evaluate risk factors associated with any SSI, superficial SSI, deep-incisional SSI, and organ-space SSI. Results Of 72,519 patients, 4906 cases of SSI were identified: 2276 superficial SSI, 357 deep-incisional SSI, and 2483 organ-space SSI. Risk factors associated with superficial SSI were admission before procedure (adjusted odds ratio [AOR] = 1.31; 95% confidence interval [CI] 1.17-1.47; P  Conclusions SSI types in patients undergoing laparoscopic colectomy have different risk factors. Modifiable risk factors may provide an opportunity to reduce SSI risk and its associated morbidity.
