Abstract
BACKGROUND: In recent years, there has been an increasing trend towards day-case surgery for patients undergoing laparoscopic cholecystectomy (LC). We investigated the predictive value that pre-operative neutrophil-to-lymphocyte ratio (PNLR) had on surgical outcomes. METHODS: A review of all patients who underwent LC during a 6-year period in a single institution was performed and PNLR recorded. A PNLR cutoff value of 3 was utilised. We compared operation time, length of stay (LOS), and conversion to open between those with PNLR less and greater than 3. RESULTS: A total of 567 patients underwent elective LC. Those with PNLR>3 had associated prolonged operation time (p < 0.005), prolonged LOS (p < 0.005), and higher rates of conversion to open surgery (p < 0.005). CONCLUSIONS: PNLR correlates with outcomes following LC. It is useful in delineating patients that have higher risk of conversion or prolonged length of hospital stay and is helpful in assessing suitability of day-case surgery.
