INFECTION, COMPLICATIONS
Percutaneous endoscopic gastrostomy (PEG) was introduced by a pediatric surgeon in 1980 [Compared to traditional surgical gastrostomy, there were fewer complications and a lower mortality rate in patients receiving PEG [Povidone-iodine is a chemical complex of povidone, hydrogen iodide, and elemental iodine. It had been applied in hand disinfection, skin preparation, and antiseptic irrigation [It is rational to expect that povidone-iodine coating gastrostomy tube would help reduce opportunities for oral microbes’ colonization and reduce the peristomal infection rate. We designed a randomized controlled trial to test the effectiveness of a povidone-iodine coating gastrostomy tube to reduce peristomal infection after percutaneous endoscopic gastrostomy.
