Bile-induced chronic gastric ulcer in swine with excised oxyntic gland area

After excision of the oxyntic gland area in seven miniature pigs and cholecystogastrostomy in six of them, two developed chronic gastric ulcers in the gastric remnant. No parietal cells were found in the two pigs with ulcers, whereas small areas with polypoid oxyntic mucosa were found in four pigs without ulcer. The study indicates that bile-induced chronic gastric ulcer can occur in the pig despite the absence of oxyntic cells.
