Backgrounds: Ambulatory laparoscopic cholecystectomy (LC) reduces healthcare cost and increases hospital bed capacity. Currently, there is no consensus on patient selection for ambulatory LC. Evaluation of risk factors for ambulatory discharge is essential. Materials and Methods: Consecutive patients who underwent LC in our centre throughout 2019 were collected. We evaluated the discharge fitness using the Post-Anaesthetic Discharge Scoring System at 8 h after the operation. The relations between pre-operative variables and dischargeable possibilities were analysed for screening risk factors. Furthermore, we performed a literature review to summarise all published information. Results: Six hundred and forty-one cases were included in this study. American Society of Anaesthesiologist (ASA) grading (odds ratio OR = 0.415, P = 0.001) and leucocytes (OR = 0.80, P < 0.001) significantly predicted the fitness of discharge. ASA contributed to lower activity (P = 0.002) and intake/output (P = 0.006) scores. Leucocytes influence the vital sign (P < 0.001) and pain or post-operative nausea and vomiting (PONV) (P < 0.001) scores. The prolonged operation could predict the inabilities of discharge with a cut-off value of 55 min by dropping vital signs (P = 0.011), activity (P < 0.001) and pain or PONV (P = 0.012) scores. Male sex (OR: 1.702, P = 0.010), body mass index (BMI) (OR: 1.087, P = 0.008), leucocytes (OR: 1.075, P = 0.017) and C-reactive protein (CRP) (OR: 1.018, P = 0.003) were predictors for prolonged operation (>55 min). Conclusions: We suggest that pre-operative ASA grading III and leucocytes are risk factors for the fitness of ambulatory discharge after LC and intraoperative time. Male, BMI and CRP predict complicated surgery, and they should be considered preoperatively.
