A 14-month-old, neutered female Miniature Pinscher was referred due to severe renal failure. The dog was treated with hysterotomy and followed by ovariohysterectomy (OHE) 6 days before the presentation. Excretory urographic and ultrasonographic studies revealed bilateral hydroureter and hydronephrosis. Postmortem necropsy revealed that ligatures were placed around the caudal portion of bilateral ureters in front of entrance into the bladder. This case shows that identifying and protecting the ureters are important during hysterotomy with OHE as well as OHE.

A 10-year-old, 8.28 kg, intact female Cocker Spaniel was presented with continuous polyuria and polydipsia. The dog had proestrus bleeding 5 weeks earlier, and hyperglycemia, glucosuria, ketouria, and high level of serum fructosamine in laboratory findings. Based on hyperglycemia, glucosuria, ketouria, and ketosis, the patient was tentatively diagnosed as diabetes mellitus (DM) with ketouria. After diagnosis, 5 to 7 U/body porcine lente insulin was administered during 11 days from initial presentation as the remission of DM for the dog. But, blood glucose was still high level. Because there was no reaction to porcine lente insulin, it was replaced by 4-10 U/body neutral protamine Hagedorn (NPH) during 3 days. But, NPH also did not regulate blood glucose level. Because insulin therapy failed to regulate blood glucose level, the dog was considering insulin-resistant diabetes. The dog was tentatively diagnosed with progesterone-resistant DM on the basis of the history that had revealed proestrus bleeding 5 weeks earlier. Progesterone level was moderate high (43.7 ng/ml; reference range, 15.0-90.0 ng/ml). Ovariohysterectomy (OHE) was performed to remove the cause of the dog's diabetes. After OHE 11 days, blood glucose was gradually declined by insulin treatment. Consequently, blood glucose was well controlled in reference range without insulin treatment after 2 months. This case is a report on progesterone-induced DM treated with OHE and insulin treatment during the diestrus.

Perioperative pain relief is essential in veterinary practice. However, the cat is one of the most poorly understood species regarding pain control management. Ovariohysterectomy(OHE) produces considerable postoperative pain in cats. Practitioners are often reluctant to administer analgesics due to lack of familiarity with available drugs, concern about side effects, or frustration with the need for record keeping of controlled substances. The purpose of this study was to determine if intraperitoneal administration of bupivacaine can provide relief of pain following OHE in cats. Twelve healthy female cats were randomly divided into two groups. OHE was performed under general inhalation anesthesia. Just prior to complete closure of the linea alba, 6 cats in SAL group received 0.88 ml/kg 0.9% saline, 6 cats in BUP group received 4.4 mg/kg 0.75% bupivacaine diluted to an equivalent volume with saline in the intraperitoneal space. Cats were scored at 0, 1, 2, 4, 8, 12 and 24 hours post-extubation by one observer. Cats were evaluated using a visual analogue scale(VAS) and composite pain scale(CPS) that included physiologic variables. There were no significant differences in body weight, anesthesia time, surgery time, and incision length between the two groups. Cats in the BUP group had significantly(p<0.05) lower VAS-pain scores than cats in the SAL group at 4, 8, 12 hours after surgery. Cats in the BUP group had significantly lower CPS scores than cats in the SAL group at 8, 12 hours after surgery. No adverse side effects were observed. These results support that the intraperitoneal administration of bupivacaine following OHE can be used for the prevention of postoperative pain and pain-induced behavioral changes in cats.

본 연구에서는 난소자궁적출술에 있어서 티타늄(titanium) 클립 적용 시 발생할 수 있는 합병증을 평가하고, 난소혈관과 난소걸이인대의 두 가지 결찰법을 비교하여 합병증을 최소화 할 수 있는 수술법을 찾고자 하였다. 실험을 위해 6마리의 암컷 비글견이 사용되었으며, 세 마리씩 두 그룹으로 나누어 한 그룹은 난소걸이인대와 난소혈관을 함께 결찰 하였고, 나머지 한 그룹은 난소걸이인대를 결찰하지 않고 난소혈관만 결찰 하였다. 두 수술법을 비교하기 위해서 매달 1회씩 1년 동안 복강 X-ray 검사를 통해 적용된 클립의 위치 변화를 확인하였고, 적용된 클립에 의한 염증반응 유무는 혈액검사를 통해 확인하였다. X-ray 검사 상에서 두 그룹의 클립 위치는 큰 변화를 보이지 않았으며, 혈액 검사에서도 거의 모든 수치들이 정상범위에 있었고, 염증과 관련된 임상증상 또한 관찰되지 않았다. 부검을 통한 두 그룹의 클립 포매 형태를 관찰한 결과 난소걸이인대를 결찰한 클립은 복강의 얇은 막으로 두껍게 싸여서 신장 후연에 위치하고 있는 것을 확인하였고, 난소걸이인대를 결찰하지 않은 클립은 얇게 둘러싸인 막 표면에 위치하여 신장의 아래쪽에서 관찰되었다. 이러한 결과는 난소걸이인대가 클립의 움직임을 최소화 할 수 있도록 지지해주는 역할을 하는 것을 의미하며, 따라서 티타늄 클립을 적용하는 난소자궁적출술에서 난소걸이인대를 함께 결찰하는 방법이 합병증 예방에 있어서 보다 적합한 방법으로 생각된다.

An eight-year-old, 3.4 kg, spayed female poodle dog was referred to Gyeongsang National University Animal Medical Center with obstinate bilateral retroperitoneal subcutaneous abscess. The medical history revealed ovariohysterectomy (OHE), lipoma, and mammary gland tumor excision performed two years ago. The dog presented with left retroperitoneal subcutaneous abscess discharge five months back and was treated by abscess drainage and antibiotics in a local veterinary hospital, but a relapse was reported on discontinuing antibiotics. On physical examination, the dog was febrile (40℃) and both retroperitoneal masses showed typical inflammatory reaction and purulent discharge. On serum chemistry analysis, hyperproteinemia, hyperglobulinemia, and elevated levels of C-reactive protein were observed. Cytologic examination showed degenerative neutrophils and phagocytic macrophages. Radiological examination revealed encapsulated hypoechoic subcutaneous masses in bilateral abdominal flank and the left flank mass was connected with the caudal pole of left kidney through fistula. Based on the diagnostic examination, exploratory celiotomy was recommended and left nephrectomy, and resection of bilateral masses were performed. During procedure, fistula between caudal pole of left kidney and left subcutaneous abscess was detected and suture material was identified. Resected tissue was histologically examined and diagnosed as suppurative abscess caused by the suture material. This case report describes chronic suppurative foreign body reaction including caudal pole of left kidney and bilateral retroperitoneal subcutaneous masses induced by the suture material used in OHE two years ago and the necessity of computed tomography examination to identify character of mass and extent of surgical resection.

An 8-year-old female pet rabbit presented at the veterinary clinic for mammary gland palpation due to the presence of a mass. Upon physical examination, a mass was identified in the left fourth mammary gland. Abdominal ultrasonography revealed a 3 × 2 cm mass in the right uterus and general thickening of the endometrium, suggesting uterine sinusitis. Multiple pulmonary nodules suspected to be metastatic lesions were identified on chest radiography. Surgery was performed to mastectomy and ovariohysterectomy (OHE). The histopathological examination of the tumor revealed mammary gland adenocarcinoma (simple-type) with multiple nodules consisting of the proliferation of tumor cells forming tubules containing secretory materials, cellular debris, and solid nests with a central area of necrosis. Metronomic chemotherapy was performed with cyclophosphamide and lomustine (CCNU) based on the histopathological findings. The quality of life has been well maintained, with no specific clinical symptoms observed for 8 months after metronomic chemotherapy. To the best of authors' knowledge, this study is the first to examine the effects of metronomic chemotherapy with cyclophosphamide and lomustine in a pet rabbit.

네 살령의 암컷 시츄견이 복부 팽만으로 내원하여 조직검사 결과 cystic papillary adenocarcinoma로 진단되었으며, 복강 장간막으로의 전이도 확인되었다. 난소 자궁 적출술을 실시하고 1달 후, 복수를 제거한 후 cisplatin을 (50 $mg/m^2$)을 0.9% 생리식염수(250 $ml/m^2$)에 희석하여 복강내로 주입하였다. 치료기간 동안 3번의 재발이 있었으나, 임상증상의 개선이 매우 뚜렷하였으며, 특별한 부작용을 보이지 않고 진단 후 33개월 간 건강 상태를 유지할 수 있었다. 그러나 11번의 항암 치료 이후에 복수와 더불어 흉수가 병발하였고, 신부전증도 동반하였다. 수액요법과 대증치료의 일환으로 복강, 흉강 천자도 실시하였으나 개선을 보이지 않고 환자는 폐사하였다. 복강 내 cisplatin의 투여법은 난소종양으로 인한 악성 복수, 흉수를 치료하는데 효과적인 완화요법으로 쓰일 수 있을 것으로 사료된다. 본 증례는 복강전이를 동반한 악성 난소 종양이 발생한 환자를 복강 내 cisplatin투여를 통해 효과적으로 치료한 한국에서의 첫 번째 보고이다.
