    Dogs with advanced chronic hepatitis respond poorly to the existing treatments. Treatment with adipose-derived mesenchymal stem cells is a novel therapeutic option. In this study, we evaluated the distribution of the adipose tissue in dogs with chronic hepatitis based on computed tomography images and attempted to collect adipose tissue using laparoscopy. This study included 25 dogs with chronic hepatitis divided into the chronic hepatitis/advanced group (n = 11) and non-advanced group (n = 14). In the chronic hepatitis/advanced group, the subcutaneous fat area was significantly smaller than the visceral fat area. Additionally, the ratio of the visceral fat area and subcutaneous fat area was significantly higher in the chronic hepatitis/advanced group than in the non-advanced group. Furthermore, laparoscopic fat collection attempted in one dog with chronic hepatitis could be performed easily. These results suggest that visceral fat can be collected more easily than subcutaneous fat in dogs with advanced chronic hepatitis. Additionally, visceral adipose tissue can be collected under scheduled laparoscopic liver biopsy in dogs with suspected chronic hepatitis.

    A mixed breed and castrated male cat, aged approximately 7 years, had decreased appetite and hypersalivation since a month. Oral examination revealed severe periodontitis and loose maxillary canines. The condition was diagnosed as anorexia due to severe periodontitis. On the 30th day of the illness, total extraction of all teeth was performed under general anesthesia. When the left mandibular canine was dried with an air syringe during the extraction procedure, swelling and crepitus were observed in the left mandibular region. Radiographic examination revealed air permeation in the lower jaw showing subcutaneous emphysema. After confirming that the vital signs did not worsen, the treatment was continued, and the remaining teeth were extracted. After the treatment, 8 mg/kg cefovecin sodium was administered subcutaneously. Crepitus was observed on the 3rd day postoperatively, but it disappeared on the 7th day. Moreover, no findings suggestive of air permeation were observed on radiography. There were no complications such as incomplete union observed in the wound. Thus, this case shows that tooth extraction has a potential risk of emphysema development. When using an air syringe, it is necessary to pay attention to the direction of the compressed air being discharged.
