Background/aims

A prospective study was performed to evaluate the incidence of bile leak after T-tube removal, using 99mTc labelled BULIDA scintigraphy.

Patients and methods

Thirty seven patients with choledocholithiasis underwent choledocholithotomy and T-tube drainage. T-tubes were removed on 9--26 postoperative day (mean 13.4 days).

Results

Six (16%) patients had scintigraphic evidence of bile leak; 4 patients had leak demonstrated in the early phase only. One patient each had partial persistent leak and complete bile leak. All patients were managed nonsurgically; conservative treatment: (4), percutaneous drainage (PCD) of intra-abdominal collection (1) and endoscopic sphincterotomy and PCD of intra-abdominal collection (1). There was no significant difference in the leak rate when T-tubes were removed at < 2 weeks versus later than 2 weeks (P=.97).

Conclusions

T-tubes should be removed with extreme caution and treatment of symptomatic patients should be guided by clinical and scintigraphic findings.
