Witzel fistula
The Witzel fistula , occasionally also Witzel fistula , is an artificial feeding channel.
This feeding tube was named after its inventor, the surgeon Oskar Witzel (1856–1925). It is used to nourish inoperable constrictions of the upper digestive tract, e.g. B. by esophageal carcinoma or gastric carcinoma , which is inserted with surgical presentation of the stomach. It was widely used until the 1980s, but PEG ( percutaneous endoscopic gastrostomy ) is now preferred. The surgical installation of a Witzel fistula is still used when the esophagus cannot be passed endoscopically. Connections from the gastrointestinal tract to the outside in the manner of a Witzel fistula are also used in other diseases of oncological surgery, for example bile duct discharge in hepatectomy.
It is an operative external gastric or intestinal fistula (especially as a nutritional fistula, e.g. as a palliative intervention for gastric cancer) with the formation of a sloping canal from extended wall folds of the organ concerned. It is loaded with a catheter (catheter gastrostomy or catheter enterostomy).
