Fig. 4. Drainage: distal end was located below the stricture, as far as possible far in the Roux-en-Y-loop, and lateral holes were located above the stricture, at the level of the segmental bile ducts. The internal drainage segment (between proximal and distal openings) allows bile to flow into the intestine. The external drainage segment provides constant flow of the bile in the intestine (between proximal and distal openings) (a, б), and the external drainage segment provides constant access to the ducts (в). |
