A Cochrane review included 5 studies with a total of 429 subjects. The trials recruited 49% of patients undergoing cholecystectomy. The selection criteria varied, but most included only patients without other diseases. The patients were living in easy reach of the hospital and with a responsible adult to take care of them. On the day of surgery, 81% of day-case patients were discharged. There was no significant difference between day-case and overnight stay group as regards to morbidity, prolongation of hospital stay, re-admission rates, pain, quality of life, patient satisfaction and return to normal activity and work. Because of the decreased hospital stay, it is likely to save costs.
Comment: The quality of evidence is downgraded by imprecise results (few patients and wide confidence intervals).
