An 8-month-old, intact male Maltese dog was referred to us because of anorexia, diarrhea, and jaundice. Hematologic examination revealed immune-mediated hemolytic anemia, and abdominal ultrasonography revealed heterogeneous changes in mesenteric fat and coarse echotexture in the splenic parenchyma. Septic peritonitis was diagnosed on the basis of a bacterial culture test of the peritoneal fluid. Exploratory laparotomy and subsequent omental biopsy and splenectomy were performed. On histopathological examination, the omental mass and splenic lesions were diagnosed as grain foreign body granulomas. This report describes a rare case in which a grain foreign body was embedded in the spleen of a dog.

신 주위 농양은 증상이 비특이적이고 다양하여 임상적으로 진단이 어렵고 치료가 늦어지기 쉬워 합병증과 사망률이 높은 질환이므로, 발열이 지속되는 경우에 감별 진단해야 하는 질환이다. 초음파 촬영술, 전산화 단층 촬영술 등은 신 주위 농양을 조기에 진단하고 적절한 치료 방향을 정하는데 유용하며, 치료 방법으로 항생제 외에 경피적 농흡인, 배농 및 수술 등의 처치가 필요하다. 저자들은 발열이 9일 동안 지속된 환아에서 경피적 배농술로 치료한 신 주위 농양 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

호두까기 증후군으로 인한 기립성 단백뇨의 보고는 적지 않다. 하지만, 아직 정확한 기전이 알려져 있지 않다. 본 증례와 같이 호두까기 증후군로 인하여 아침 첫 소변에서도 단백뇨가 나오고, 하루 1 g 이상의 단백뇨가 지속적으로 나올 수 있다는 보고는 아직 없다. 또한, 대동맥뒤 왼쪽 콩팥정맥의 경우에 단백뇨가 많이 나올 수 있다는 보고도 아직 찾을 수 없었다. 본 증례에서 단백뇨의 원인이 뒤 호두까기 증후군이라는 직접적인 증거는 없지만, 다른 단백뇨의 원인을 찾을 수 없었다. 만일 뒤 호두까기 증후군으로 인해 다량의 단백뇨를 유발할 수 있다는 것이 사실이라면, 좌측 신정맥에서 발생하는 강력한 혈역학적인 변화 자체가 직-간접적으로 사구체 상피세포의 손상을 유발시켰음을 암시하는 것으로 사료된다.

Ganglioneuroma of the gastrointestinal tract is a rare tumor that consists of ganglion cells, nerve fibers, and supporting cells of the enteric nervous system. Ganglioneuromas are usually associated with genetic disorders such as the multiple endocrine neoplasia syndrome or neurofibromatosis. Ganglioneuromas of the gastrointestinal tract predominantly involve the colon and rectum, and reports about duodenal ganglioneuromas are few. Herein, we report a case of duodenal ganglioneuroma treated with endoscopic resection. A 56-year-old female patient visited our hospital because of a subepithelial tumor in the second portion of the duodenum. She had no remarkable medical or family history and revealed no history of genetic disorders. Endoscopic ultrasonography and abdominal computed tomography revealed a tumor located mainly in the submucosal layer, without any regional lymph node involvement. Endoscopic resection of the lesion was performed, and the pathological examination confirmed a duodenal ganglioneuroma.

난소위체 낭종은 대부분 양성 단순 낭종의 형태로 나타나며 자궁부속기 종괴의 10~20%를 차지한다. 경계성 혹은 악성 난소위체 종양은 드물며, 매끈한 내부 벽에 유상돌기를 포함한다. 저자들은 2일간의 좌하복부 불편감을 주소로 내원한 19세 여성에서 발생한 난소위체 장액성 경계성 종양을 경험하여 초음파, 컴퓨터단층촬영과 자기공명영상의 소견을 보고하고자 한다.

Recently, endoscopic screening systems have enabled the diagnosis of gastric cancer in the early stages. Early gastric cancer (EGC) is typically characterized by a shallow invasion depth and small size, which can hinder localization of EGC tumors during laparoscopic surgery. Here, we review nine recently reported tumor localization methods for the laparoscopic resection of EGCs. Preoperative dye or blood tattooing has the disadvantage of spreading. Preoperative 3-dimensional computed tomography reconstruction is not performed in real time during laparoscopic gastrectomy. Thus, they are considered to have a low accuracy. Intraoperative portable abdominal radiography and intraoperative laparoscopic ultrasonography methods can provide real-time feedback, but these methods require expertise, and it can be difficult to define the clips in some gastric regions. Despite a few limitations, intraoperative gastrofibroscopy provides real-time feedback with high accuracy. The detection system using an endoscopic magnetic marking clip, fluorescent clip, and radio-frequency identification detection system clip is considered highly accurate and provides real-time feedback; we expect a commercial version of this setup to be available in the near future. However, there is not yet an easy method for accurate real-time detection. We hope that improved devices will soon be developed and used in clinical settings.

A 10-year-old spayed female Maltese with a history of vomiting and lethargy was referred to the hospital. Physical examination revealed dehydration and severe pain following abdominal palpation. A large mass was observed in the cranial abdomen through radiography and ultrasonography. Laparotomy was performed to find the origin of the mass. The mass was about 8 cm originating from the cecum and subsequently removed. Histopathologic evaluation revealed that the cecal mass was suspected to be a mesenchymal-derived tumor. Through immunohistochemistry, the mass was diagnosed as a gastrointestinal stromal tumor (GIST) based on the c-kit expression. Given its recurrence, postoperative preventive therapy was initiated with masitinib mesylate, which is a tyrosine kinase inhibitor. The animal did not show any side effects during the medication period. After 6 months of therapy, it was well controlled without any recurrence. In this case, we introduced a novel postoperative management of GIST using masitinib mesylate.

본 연구는 2021년 10월부터 2021년 12월까지 부산 소재 I 병원을 내원한 환자와 건감검진 대상 중 간 초음파와 Fibroscan 검사를 모두 시행한 441명의 검사 결과지를 후향적으로 분석하였다. 연구 목적은 간 초음파를 이용한 지방간 평가와 Fibroscan을 이용한 지방간 평가의 상관관계분석 및 카이제곱검정을 시행하여 지방간 평가에 있어 Fibroscan의 유용성을 알아보고자 하였다. 복부초음파의 지방간 판독 결과와 Fibroscan UAP의 상관관계 분석 결과 r=0.600, p=0.000으로 나타나 상관관계가 확인되었다. 지방간 평가에 있어서 Fibroscan은 지방간 수치로 하여 객관적인 결과를 예측하는데 높은 타당도를 보였다.

A 9-year-old, intact female Shih-tzu dog presented with a three-week history of anorexia, lethargy, and weight loss. Abdominal radiography revealed a mass in the right cranial quadrant of the abdomen that was displacing the right kidney caudally. Ultrasonography showed a large, irregular, heterogeneous hepatic mass and a small amount of peritoneal fluid. On computed tomography (CT), a large hypoattenuating mass with heterogeneous contrast enhancement occupied the right lateral lobe, and parts of the right medial and caudate lobes of the liver. There was no evidence of regional lymph node or pulmonary metastasis. Lobectomy of the right medial, right lateral and caudate liver lobes was performed, however, the patient did not recover from surgery. Hepatoblastoma was confirmed by histological examination. Hepatoblastoma is rare in dogs, and this is the first report describing CT imaging of hepatoblastoma in a dog.

Background: In solid organ transplantation patients, complications of cholelithiasis may run a fulminant course, resulting in high morbidity and mortality under immunosuppression and may even result in rejection. Here, we reviewed medical records of 66 patients in order to determine the outcome of management approach for asymptomatic gallstones in renal transplantation patients. Methods: We retrospectively reviewed clinical courses of 66 cases of renal transplantation performed between 2000 and 2012 at Kosin University Gospel Hospital. Results: Among 66 cases, eight had gallstones before transplantation. Three of these cases had undergone previous cholecystectomy for symptomatic gallstones, one had a simultaneous laparoscopic cholecystectomy and renal transplantation, and four were observed by regular abdominal ultrasonography. One patient was found to have cholangitis, and endoscopic retrograde biliary drainage was performed, resulting in alleviation of symptoms. Among 58 cases without preoperative gallstones, three developed gallstones after transplantation. One patient had cholecystitis, and the symptoms subsided after conservative treatment. Conclusions: For patients with asymptomatic gallstones who are awaiting renal transplantation, expectant management should be considered.
