venoperitoneostomy

An obsolete operation involving insertion of the cut end of the saphenous vein into the peritoneal cavity in cases of ascites; the vein is inverted so that the valves prevent regurgitation of blood into the cavity while the ascitic fluid flows into the vein. [veno- + peritoneum + G. stoma, mouth]
