(a) Construction of the VAC-instillation tubes with washing tube (red) and suction “sleeve” tubes. Arrows indicate the destination of washing solution flow. Outer tube with 10–15 side holes 1 cm from the blind distal end. ((b)–(d)) Representative OA cases treated with topical instillation and VAWCM. The topical solution (saline) flowed across the open abdomen to 300–500 mL/h, to clean and flush the abdomen. The abdominal fluid was captured by the VAC system.
