An 8-year-old potbellied pig was evaluated for anorexia, decreased fecal production, signs of depression, inappetence, and abdominal distension. During hospitalization, a tooth root impaction and abscess were diagnosed, and abdominal radiography revealed severely distended, gas-filled large and small intestines. Exploratory laparotomy revealed a stricture of the proximal centripetal loop of the spiral colon and megacolon of the proximal portion of the spiral colon and cecum. A side-to-side spiral colon anastomosis was performed to create a partial bypass of the spiral colon. The success of this procedure suggests that spiral colon bypass is a treatment option for spiral colon stricture formation in potbellied pigs. Spiral colon stricture formation should be considered as a differential diagnosis in geriatric potbellied pigs that are anorectic, have abdominal distension, and have decreased fecal production.

To evaluate the clinical value of multi-slice spiral CT in preoperative TNN staging and postoperative recurrence and metastasis of colon carcinoma, and to provide evidence for the reliability of CT in the diagnosis of colon carcinoma METHODS: 89 patients with colon carcinoma diagnosed pathologically in our hospital from July 2020 to April 2023 were selected retrospectively. The preoperative TNN staging and postoperative recurrence and metastasis were monitored by 64 row 128 layer spiral CT. The diagnostic coincidence rate, TNM staging coincidence rate and postoperative recurrent TNM staging accuracy were evaluated according to the pathological diagnosis RESULTS: The diagnostic coincidence rate of multi-slice spiral CT was 97.

Introduction: The gastrointestinal microbiota profoundly influences the health and productivity of animals. This study aimed to characterize microbial community structures of the mouth, gastrointestinal tract (GIT), and feces of cattle.
Methods: Samples were collected from 18 Akaushi crossbred steers at harvest from multiple locations, including the oral cavity, rumen, abomasum, duodenum, jejunum, ileum, cecum, spiral colon, distal colon, and feces.

We report the case of a 74-year-old male with abdominal pain, distention and obstipation for 8 hours. He had a medical history of 24 sigmoid volvulus (SV) episodes, 23 of which treated with endoscopic detorsion, while one resolved spontaneously. Physical examination revealed abdominal distention, tenderness, hyperkinetic bowel sound and an empty rectum.

Article Synopsis
- Torsion of the spiral colon (TSC) is a serious condition in cows characterized by twisting of the spiral colon, often leading to severe health issues and abnormal vital signs such as increased heart rate and breathing difficulties.*
- In a study of 58 cows, common clinical signs included an empty rectum, reduced rumen motility, and dilated intestines, with a significant percentage showing biochemical imbalances like hypermagnesemia and acidosis.*
- Treatment primarily involved surgery, where 53 cows underwent right flank laparotomy, resulting in a survival rate of about 44.8%, while over half of the cows were euthanized due to their condition.*
