Background: We developed a minimally invasive technique of esophagostomy called percutaneous transesophageal gastrotubing (PTEG) using a rupture-free balloon (RFB) for enteral nutrition and drainage as well as percutaneous endoscopic gastrostomy (PEG). PTEG using RFB allows surgeons to create a nonsurgical esophagostomy even in difficult cases of PEG (i.e., total gastrectomized patients and massive ascites).
Methods: To create the PTEG, a RFB is inserted into the esophagus through the nose and inflated. The RFB is punctured with a needle at the left neck under ultrasonographic vision. A guidewire is inserted through the needle, followed by dilatation of the punctured site using a dilator with sheath. Finally, the tube is inserted into the gastrointestinal tract and the sheath is peeled off.
Results: From January 1998 to June 2002, we treated 115 patients using PTEG with a RFB and there were no major complications. Therapeutic results are as good as those for PEG and it took approximately 15 min to perform.
Conclusions: PTEG with RFB is as safe as PEG and is simple and less invasive. It can be used in some cases for which PEG is contraindicated.
