Background: To study mortality and infectious complications (IC) risk relative to operative duration in a large and contemporary cohort of patients undergoing hepatectomy. Methods: A retrospective cohort study of 21,443 patients from the National Surgical Quality Improvement Program dataset of patients who underwent liver resection from 2012 to 2016. Results: Patients undergoing hepatectomy during the study period (N = 21,443) had a mean operative duration of 243.5 min of which 16.6% (3533) developed at least one IC. The overall 30-day mortality was 1.6%. A significant increase in mortality and IC was demonstrated from 3 h of operating time (OR: 1.99 and OR: 1.94, respectively), peaking at 8 h (OR: 7.15 and OR: 6.37, respectively). Pneumonia, sepsis/septic shock, and SSI presented high prevalence and were linked to significant mortality. After case-matching, elective hepatectomy was associated with a 4-fold increased risk of infectious complications. Conclusions: Operative duration was associated with a linear increased risk of mortality and IC after hepatectomy. The most critical determinants of IC were ASA class, COPD, CHF, and type of hepatectomy.
