Introduction  Cervical esophagostomy has been variously utilized in the experimental laboratory for sham feeding, for introducing food into the stomach without its being masticated, or for collecting specimens of saliva. The classic operation is done in two stages: A loop of cervical esophagus is first exteriorized, and later a double stoma may be produced, or the distal limb may be occluded if desired. When either preparation is used, the maintenance of nutrition obviously is a problem, and the procedure is therefore undesirable for a long-term experiment.The following procedure produces a cervical fistula which allows easy passage of a tube or catheter into the distal part of the esophagus and yet, by its position and size, allows little loss of saliva or food. Consequently, the animals remain in excellent physical condition without the need for special care.
