INTRODUCTION

The advantages of single-stage treatment of cholecystocholedocholithiasis are well established, but the conditions for carrying out treatment on an outpatient basis require a review of concepts and practices of medical corporations.

OBJECTIVE

To evaluate the practice of treating cholecystocholedocholithiasis by laparoendoscopy on an outpatient basis with cost analysis.

METHOD

A retrospective study was conducted on patients with cholecystocholedocholithiasis treated by combined laparoscopic cholecystectomy and endoscopic choledocholithotomy from January 2015 to January 2019. After collecting data from physical and digital medical records, the patients were divided into two groups-AR ( = 42)-ambulatory regimen and HR ( = 28)-hospitalization regimen-which were compared in terms of demographic, clinical and treatment variables and their results, as well as in terms of costs.

RESULTS

The mean age of the AR group was lower than that of the HR group and the physical status of the AR patients was better when assessed according to the American Society of Anesthesiologists (ASA) ( = 0.01). There was no difference between groups regarding the risk of choledocholithiasis ( = 0.99). For the AR group, the length of stay was shorter: 11.29 h × 65.21 h ( = 0.02), as was the incidence of postoperative complications assessed by applying the Clavien-Dindo classification: 3 (7.1%) × 11 (39.2%) ( < 0.01). The total mean costs were higher for the HR group (USD 2489.93) than the AR group (USD 1650.98) ( = 0.02).

CONCLUSION

Outpatient treatment of cholecystocholedocholithiasis by laparoendoscopy is safe and viable for most cases, has a lower cost and can support the reorientation of training and practice of hepatobiliary surgeons.
