[New techniques of postoperative cholelith endoscopy via the "T" tube fistula].

OBJECTIVE
to explore some new techniques of postoperative cholelith endoscopy via the fistula.


METHODS
Netting, washing, clamping, pushing, and electrohydraulic techniques were used in 260 cases of postoperative cholelith endoscopy via the fistula and the clinical data were analyzed retrospectively.


RESULTS
The stones in 257 cases (98.8%) were removed completely in an average of 2.7 times. Three patients were operated on again because of biliary stricture and huge stones.


CONCLUSION
The application of some new techniques in postoperative cholelith endoscopy via the fistula favors the complete removal of stones.
