Use of intraoperative cholangiography in patients diagnosed with choledocholithiasis with preoperative imaging or endoscopic study.

BACKGROUND

Cholecystectomy is one of the most performed procedures worldwide. Many surgeons defend the use of routine intraoperative cholangiography (IOC), but this action is getting less practiced because other preoperative tools that can omit IOC.

OBJECTIVE

Evaluate the utility of performing intraoperative cholangiography in patients whom got a preoperative imaging or endoscopy study. We analized the association between the diagnostic-therapeutic approach and hospital readmissions because of bile duct obstruction.

METHOD: Retrospective and comparative study of 117 patients admitted with choledocholithiasis and submitted to cholecystectomy between January 2014 and December 2016. The statistical analysis was performed comparing groups using chi squared test with a statistical significance of p < 0.05.

RESULTS

Patients whom got a preoperative study and had performed an intraoperative cholangiography didn't readmitted. The study reported nine readmissions, being residual gallbladder stone the diagnostic. Patients whom didn't get an intraoperative cholangiography reported the most readmissions. The studied group who registered the most readmissions was the one who didn't get performed an intraoperative cholangiography nor a preoperative study. No mortality was reported.

CONCLUSION

Patients who had IOC performed reported less readmissions for residual stone.
