The cecal resection indicated disorders such as impaction, inversion, perforation, dilatation, neoplasia, and severe inflammation (typhlitis). The cecum surgical ablation depends on the disease's progression and stringency; the cecum can be excised partially or completely from the colon. This study aimed to investigate the histopathological findings and provide a comparative analysis of cecal tissue following partial and complete typhlectomy in dogs, offering insights into the comparative outcomes and implications aiding in surgical decision-making and postoperative management strategies. Tissue samples from the cecum were collected from two dogs who underwent exploratory laparotomies two months later, either partial or complete typhlectomy procedures, and were subjected to histopathological examination. The results reveal distinct histopathological changes associated with each surgical approach, demonstrating that partial typhlectomy involved more active repair and healing processes in the cecal intestinal wall layers compared to the changes in granulation or organized tissue proliferation in complete typhlectomy. Partial typhlectomy was characterized by more active lymphoglandular complexes and peripheral lymphoid follicle formations having vast, clear germinal centers, while complete typhlectomy had fewer active changes. The mucosa surface looked near normal histology after a partial typhlectomy. In contrast, in a complete typhlectomy, the upper villi appeared short and thickened due to connective tissue proliferation and dilated lacteal ducts. In Conclusion, the histopathological results show distinct tissue responses. The comparative analysis indicates differences in tissue damage and healing and revealed that partial typhlectomy resulted in an enhanced or more advanced degree of repair than complete typhlectomy in dogs.
