A 10-year and 8-month-old male beagle with vomiting, anorexia and icterus presented to our veterinary hospital. Based on ultrasonography of the abdominal cavity and blood laboratory testing, the dog was diagnosed with gallbladder mucoceles accompanied by extrahepatic biliary obstruction. Because medical treatments did not effectively improve the dog’s clinical symptoms, surgical treatment was scheduled. An experimental laparotomy showed a large dilated and slightly white discolored gallbladder and a marked dilated extrahepatic bile duct. Total cholecystectomy was intended as a surgical treatment for the gallbladder mucoceles, but because of severe adhesion between the gallbladder and liver, the gallbladder was first incised and the contents removed. However, the extrahepatic biliary obstruction remained unresolved despite bile duct irrigation. Therefore, a subtotal cholecystectomy followed by cholecystojejunostomy using the remaining gallbladder was performed to form a bile outflow route. Postoperative recovery was uneventful, and the dog’s clinical symptoms, including icterus, have improved. The dog remains in good physical condition 6 months after surgery. This surgical method was useful in a dog with extrahepatic biliary obstruction in which the obstruction was difficult to remove.

A dog with a large prostatic abscess in the pelvic cavity was treated with total prostatectomy. The prostate was continuous with a large abscess. The abscess, which had adhered to the surrounding tissue in the pelvic cavity, was carefully detached. The caudal part of the urethra was preserved. Postoperative urinary incontinence was mild and gradually improved. Two years after surgery, normal urination was possible, and the abscess had not recurred. Total prostatectomy, which is considered to be associated with many complications, may be useful for the treatment of large prostatic abscesses.

A 7-year and 8-month-old female rabbit presented with severe hemorrhagic discharge from the vulva. An ovariohysterectomy was performed, and then seven large nodules in the uterus and several small nodules on the uterine mesometrium were detected. The uterine nodules were diagnosed as adenocarcinomas, among which three were classified as papillary type and four were classified as tubular/solid type. The small nodules on the mesometrium were also diagnosed as tubular/solid adenocarcinomas, which were suspected to have been due to disseminated metastasis from the uterine myometrium into the mesometrium. The tumor cells of the tubular/solid adenocarcinoma had conspicuously infiltrated the myometrium, and some had invaded the uterine mesometrium. The rabbit suddenly exhibited anorexia and died 5 months after the surgery. Necropsy revealed marked thickening of the greater omentum and numerous small nodules on the intestinal mesometrium where tubular/solid adenocarcinomas were detected.
