Acceptance of Ambulatory Laparoscopic Cholecystectomy in Central Switzerland

Abstract

Background

Currently, most patients undergoing laparoscopic cholecystectomy (LC) in Switzerland are inpatients for 2–3 days. Due to a lack of available hospital beds, we asked whether day-case surgery would be an option for patients in central Switzerland. The questions of acceptability of outpatient LC and factors contributing to the acceptability thus arose.

Methods

Hundred patients suffering from symptomatic cholecystolithiasis, capable of communicating in German, and between 18 and 65 years old, were included. Patients received a pre-operative questionnaire on medical history and social situation when informed consent on surgery and participation in the study was obtained. Exclusion criteria were patients suffering from acute cholecystitis or any type of cancer; having a BMI >40 kg/m²; needing conversion to open cholecystectomy or an intraoperative drainage; and non-German speakers. Surgery was performed laparoscopically. Both surgeon and patient filled in a postoperative questionnaire. The surgeon’s questionnaire listed medical and technical information, and the patients’ questionnaire listed medical information, satisfaction with the treatment and willingness to be released on the same day. These data from both questionnaires were grouped into social and medical factors and analysed on their influence upon willingness to accept an ambulatory procedure. No outpatient follow-up apart from checking for readmission to our hospital within 1 month after discharge was performed.

Results

Of the 100 participants, one-third was male. More than two-thirds were Swiss citizens. Only one participant was ineligible for rapid release evaluation due to need of a drainage. Among the social factors contributing to the acceptability of ambulatory care, we found nationality to be relevant; Swiss citizens preferred an inpatient procedure, whereas non-Swiss citizens were significantly more willing to return home on the same day. Household size, sex and age did not correlate with a preference for inpatient care in our study population. Furthermore, medical input factors such as the surgeon’s level of experience, operation time or use of local anaesthesia at the end of surgery had also no significant influence on whether patients preferred inpatient care or not. Medical output factors not found to contribute to the patients’ decisions included co-morbidities or postoperative nausea and vomiting (PONV). Patients of experienced surgeons reported significantly less pain at the operation site. This was correlated with a somewhat increased willingness to accept ambulatory treatment.

Conclusion

Given the choice, about half of the LC patients in central Switzerland prefer to stay in hospital overnight. PONV, age, sex or social surroundings were not predictive of the preferred treatment modality. Only being a non-Swiss citizen and experiencing little pain at the operation site due to the surgeon’s skills seem to be factors that lead to a preference for ambulatory LC (ALC). Therefore, ALC in central Switzerland is most acceptable to non-Swiss citizens, operated upon by experienced surgeons.
