A 3-year-old female red corn snake was presented for a three-week history of anorexia and decreased defecations. On physical examination, a soft midbody intracoelomic swelling was palpated. Transcutaneous coelomic ultrasound revealed a target-like mass on a transverse section of the stomach, suggesting the presence of a gastrointestinal intussusception. On exploratory coeliotomy, a double compounded esophagogastric and gastroduodenal intussusception was diagnosed and reduced surgically. A gastropexy was also performed to prevent recurrence. On histopathology, the gastric glandular mucosa showed moderate to marked proliferation. Diffusely lining the luminal surface of glandular epithelium and free within the lumen were a myriad of protozoa consistent with sp. A diagnosis of chronic proliferative gastritis due to sp. was made based on these findings. Intussusceptions are rare in reptiles and are infrequently reported in snakes. This is the first report of a double compounded intussusception in a nonmammalian species and the first report of an intussusception involving the stomach in a snake with gastritis due to sp.
一条3岁雌性红玉米蛇因厌食和排便减少三周前来就诊。体格检查时，可触及腹腔中部有一个柔软的肿胀。经皮腹腔超声显示胃横断面上有一个靶样肿物，提示存在胃肠套叠。在剖腹探查术中，诊断为双重复合性食管胃和胃十二指肠套叠，并进行了手术复位。还进行了胃固定术以防止复发。组织病理学检查显示，胃腺黏膜呈中度至重度增生。在腺上皮的管腔表面弥漫性排列并游离于管腔内有大量与 种一致的原生动物。基于这些发现，诊断为由 种引起的慢性增生性胃炎。套叠在爬行动物中很少见，在蛇类中也鲜有报道。这是首例关于非哺乳动物双重复合性套叠的报告，也是首例关于因 种导致胃炎的蛇发生涉及胃的套叠的报告。
