Outpatient laparoscopic cholecystectomy in Hong Kong Chinese -- an outcome analysis

Laparoscopic cholecystectomy (LC) is now the procedure of choice for symptomatic gallbladder disease. Although many recent studies, mostly from abroad, report that it can be performed safely in the outpatient setting, the experience of outpatient LC in Hong Kong is still limited. This retrospective study evaluated the feasibility, safety and patient acceptance of outpatient LC in Hong Kong Chinese patients.

The data of 73 consecutive patients who had undergone outpatient LC between February 2000 and October 2002 in the Day Surgery Centre of Tung Wah Hospital were prospectively collected and reviewed. The selection criteria for patients undergoing outpatient LC included American Society of Anesthesiologists risk classification I or II, age less than 70 years, and the availability of a competent adult to accompany the patient home and look after them for 24 hours. No effort was made to exclude complicated cases. After assessment by the operating surgeon, patients were discharged from the Day Surgery Centre in the afternoon when their clinical condition satisfied pre-defined discharge criteria. All patients were followed up in the Day Surgery Centre in the first and fourth postoperative weeks.

The same-day discharge rate was 88% and the conversion rate was 4%. Six patients (8.2%) with uneventful LC required hospitalization after the procedure. There was no major complication and no unplanned admission. Two patients had port site wound infection requiring hospital admission at the first follow-up. Patient satisfaction was high, pain acceptance was good, and analgesic consumption was minimal. Mild fat intolerance was common in patients postoperatively (> 50%), but this had almost all resolved by postoperative week four. All patients were able to resume their usual daily activities within 2 weeks after surgery.

LC is a safe and feasible outpatient procedure in Hong Kong, with high levels of patient satisfaction. A prospective study with a larger patient population is warranted to verify whether it should be recommended as treatment for gallstone disease in selected patients in future.
