    Abstract:
    BACKGROUND: The studies that established historical rates of surgical infection after cholecystectomy predate the modern era of laparoscopy and routine prophylactic antibiotics. Newer studies have reported a much lower incidence of infections in "low-risk" elective, outpatient, laparoscopic cholecystectomies. We investigated the current rate of postoperative infections in these cases within a large, U.S. METHODS: We retrospectively reviewed elective laparoscopic cholecystectomies from the 2016-2017 American College of Surgeons National Surgical Quality Improvement Program database. Our primary outcome was postoperative surgical site infection; secondary was Clostridium difficile infection. Logistic models evaluated the associations of patient and operation characteristics with these outcomes. RESULTS: Surgical infection occurred in 1.0% of cases (293/30,579). Cdifficile infection occurred in 0.1% (31 cases). In our adjusted multivariable models, other/unknown race/ethnicity, diabetes, hypertension, smoking, American Society of Anesthesiologists >2, operative minutes, and wound class 4 were associated with a significantly higher odds of surgical infection; no covariates were significantly associated with Cdifficile infection. CONCLUSIONS: In the setting of modern U.S. surgical practice, the incidence of infection after elective laparoscopic cholecystectomy is very low, on par with clean cases. Our study identified several patient characteristics that were strongly associated with surgical infection. Many of these are not included as risk factors in current guidelines for antibiotic prophylaxis and may help to identify those at higher risk for this rare complication.
