The aim of this experimental study was to perform computed tomography lymphography (CTLG) of the head and neck in dogs. Five clinically healthy adult beagles and five cases were included in this study. In the majority of dogs, the sentinel lymph node (SLN) was the mandibular lymph node of the ipsilateral side of the injection site. However, in the group that received injections on the rostral mandibular lymph node, a case in which the SLN was the mandibular lymph node of both the ipsilateral and contralateral sides was confirmed. Furthermore, there was a case in which the medial retropharyngeal lymph node was the SLN. In this study, we confirmed that there were individual differences in the SLN of the head and neck in dogs. Therefore, CTLG can be considered highly beneficial in the preoperative examination of dogs with oral tumors.

Laparoscopy and endoscopy cooperative surgery (LECS) is a newly developed concept for tumor dissection of the gastrointestinal tract in human medicine. However, LECS is not common in veterinary medicine. In this study, we performed LECS gastropexy for two healthy adult Beagles.LECS gastropexy is simpler and easier than other gastropexy techniques. Moreover, perioperative complications were not observed in any of the dogs treated in this study. LECS gastropexy was supposed to be safe, minimally invasive, and highly useful technique for preventive gastopexy. Since this study used experimental models, its usefulness should be evaluated in future cases.

Encapsulating peritoneal sclerosis (EPS) is a rare clinical syndrome characterized by the fibrous sclerosis and adhesion of the abdominal organs. We have recognized three dogs with similar condition of human EPS, and had obtained characteristic findings such as thick membrane surrounding the intestines or the intestines gathering together by Echo and CT scan. We did surgical and medical therapy, and hypothesized that the results of surgical reduction affect the dog’s prognosis.
