A 2-year-old female Maltese dog was presented with a history of anemia and vaginal hemorrhagic discharge. Physical examination revealed severe vaginal hemorrhagic discharge, abdominal pain, pale mucous membranes, low blood pressure and dehydration. Results of serum biochemistry, hematology, venous blood gas, and electrolyte canine C-reactive protein (CRP) test revealed severe normocytic normochromic anemia, severe neutropenia, a high level of CRP, hypoglycemia, and imbalanced electrolytes. Abdominal ultrasound examination showed focal hypoechoic defect with loss of layering in uterine horn wall. A laparotomy revealed a clear reddish fluid in the abdomen, the fistula of left and right uterine horn, the purulent discharge from fistula, and symptoms of septic peritonitis near by the fistula site. The bitch underwent ovariohysterectomy and recovered without complication. Histopathological diagnosis of the uterine fistula site was adenocarcinoma.

경피경간담즙배액술은 담석, 양성협착, 악성종양 등에 의한 폐쇄성 황달을 감압시키기 위한 방사선학적 방법이다. 담관을 통한 담즙의 내부배액이 회복되면 경피경간담즙배액 도관은 경피적으로 제거할 수 있다. 본례에서는 병상에서 경피경간담즙배액 도관을 제거할 때, 도관이 복강으로 이동하여 복막염이 발생하였고 경구내시경으로 도관을 제거하였다. 경피경간담즙배액 도관을 제거할 때는 도관이 복강으로 이동하지 않도록 주의하여야 하며, 부주의로 인하여 도관이 복강으로 이동하였을 경우에는 경구내시경으로 도관을 제거할 후 있다.

Micrococcus lutus is common gram-positive aerobic cocci present in soil, water, dust, and the skin of humans and animals. A 72-year-old man was admitted to the hospital with a complaint of abdominal pain and a turbid peritoneal dialysate. He was empirically treated with intraperitoneal (IP) cefazolin and ceftazidime. Seven day after admission, Gaffkya species was identified from the peritoneal effluent. He was treated with same organism one month ago and discharged with the dialysis catheter intact. So, we suspected that organism is true pathogen, and identified M. luteus by culture. We changed the antibiotics to cefoxitin, which were given for the total of 14 days. This is the first report of relapsing peritonitis by M. luteus and successful treatment without catheter removal.

Peritonitis is a common, major complication in continuous ambulatory peritoneal dialysis (CAPD) patients and tuberculous (TB) peritonitis has been reported to constitute 1-2% of all peritonitis cases. In CAPD patients, TB peritonitis is often diagnosed late and has a high mortality rate. In a recent recommendation made regarding the treatment of TB peritonitis, primary removal of a peritoneal dialysis catheter has been advised in addition to anti-TB drugs. Here, we describe two cases of TB peritonitis in CAPD patients successfully treated without peritoneal dialysis catheter removal.
