Enclosed Passive Infraversion Lavage-Drainage System (EPILDS): A Novel Safe Technique for Local Management of Early Stage Bile Leakage and Pancreatic Fistula Post Pancreatoduodenectomy

This study's objective was to test the new drainage apparatus called enclosed passive infraversion lavage-drainage system (EPILDS) in the treatment of bile leakage and pancreatic fistula Post Pancreatoduodenectomys. The EPILDS device has a design of a siphon. The inlet bag that contains the rinse liquid is put lower than the abdominal lacuna to be washed but higher than the outlet bag. The hydrostatic pressure difference between the inlet and outlet bags constitutes the driving force of the flow. The three-way cock valves are installed in the inlet and outlet tubes to facilitate the washing of occluded tubes. Two side by side Penrose drainage tubes were placed during the operation. One tube passed through the posterior side of pancreatico-jejunal and biliary-jejunal anastomoses, right paracolic gutter, and exited through an opening made in the right lower abdomen. Second tube came from the smaller sac, went through the anterior side of pancreatico-jejunal and biliary-jejunal anastomoses, and exited through an opening made in the left upper abdomen. Using this system, we successfully treated two patients. Both inlet and outlet volumes were observed to verify that the outlet exceeds the inlet volume. In conclusion, EPILDS has a simple and practical design. It changes the active washing process into a passive one, in which the input is controlled by the exiting fluid. This is the effective and safe system for treatment of severe bile leakage and pancreatic fistula at the early postoperative stage.
