P71 Investigating the rate of successful day case discharges for laparoscopic cholecystectomies between June-November 2019

Laparoscopic Cholecystectomy (LC) is the gold standard treatment for symptomatic gallstones. The British Association of Day Surgery (BADS) recommend that at least 60% of LCs are performed as day cases. We investigated the rate of successful discharge for LCs and factors contributing to unexpected overnight stays. Methods Retrospective data analysis was performed on elective LCs between June-November 2019. Electronic records were reviewed for: admission and discharge date; time of procedure; length of procedure; training grade of the surgeon; use of total intravenous anaesthesia (TIVA) or volatile anaesthesia; use of IV morphine in theatre/recovery and reasons for failed discharge. Results A total of 119 patients underwent elective LC, of which 63 were planned day cases. 46 patients (73.0%) listed as day cases were successfully discharged the same day. LCs performed before 1pm had a success rate of 78.8% compared to 45.5% after 1pm (p < 0.05). There was no statistically significant difference in success rates due to length of procedure; training grade of the surgeon; method of induction (TIVA or Volatile) or use of IV morphine in theatre/recovery. 17 planned day cases failed same day discharge. 7 of these patients (41.2%) reported pain and 4 (23.3%) reported nausea, vomiting or dizziness. Conclusion This centre successfully discharged 73.0% of planned day case LCs, although only 52.9% of elective LCs were listed as day cases. Success rates were positively associated with am procedures compared to pm. We recommend a review of operation scheduling and evening staffing in order to increase the probability of discharge on the same day.
