[Choledocholithiasis in nonstandard situations: possibilities of combined methods of minimally invasive intervention].

The possibilities of minimally invasive combined interventions were shown in treatment of 49 patients with choledocholithiasis in nonstandard situations. The worked out and used minimally invasive combined operations allow ablation of concrements from bile ducts in patients who had undergone such operations as Billroth-II gastric resection and extirpation of the stomach and when cannulation of the major duodenal papilla is not possible. The authors have extended the possible application of minimally invasive methods of lithoextraction in patients with choledocholithiasis in nonstandard situations.
