Preparation of a chronic gastric fistula in the rat.
A stainless steel gastric cannula was surgically implanted in the rat forestomach to allow gastric secretion to be collected continuously without restraining the animal. When gastric collections were not being made, the cannula was closed with a plugging screw. Rats with these cannulas were easily maintained without special care or complications for 12 months.
