Intussusception of the spiral colon was diagnosed in a 3-year-old Charolais bull. Necropsy revealed the intussusception to involve approximately 40 cm of the first centripetal gyrus of the spiral loop, beginning 70 cm distal to the ileocolic junction. Predisposing lesions were not noticed in the mesentery or lumen of the affected intestine; however, the involved intestine was necrotic. Surgical resection of the lesion was not attempted because of the compromised nature of the involved large intestine and because of the inability to exteriorize the region in the standing animal.

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.*
Background: Colon cancer is a common malignant tumor that often leads to intestinal obstruction, resulting in significant morbidity and mortality. Early and accurate diagnosis of colon cancer and associated ileus is crucial for timely treatment and improved patient outcomes. Various diagnostic methods, including MSCT and MRI, are currently used in clinical practice.

Dual-nozzle fused deposition modeling (FDM) is a 3D printing technique that allows for the simultaneous printing of two polymeric filaments and the design of complex geometries. Hence, hybrid formulations and structurally different sections can be combined into the same dosage form to achieve customized drug release kinetics. The objective of this study was to develop a novel bicompartmental device by dual-nozzle FDM for colon-specific drug delivery.
