Common bile duct obstruction secondary to chronic fibrosing pancreatitis: treatment by use of cholecystoduodenostomy in the dog

Six small to medium-sized, middle-aged, female dogs with histories of acute pancreatitis developed clinical signs of extrahepatic biliary obstruction. Clinical findings were similar in the 6 dogs and included icterus. Serum biochemical analyses indicated high concentrations of total bilirubin and cholesterol and high alkaline phosphatase and alanine transaminase activities. Exploratory abdominal surgery was performed in each dog. Each dog had a firm mass involving the body of the pancreas, with obstruction of the distal portion of the common bile duct, marked peripancreatic inflammation, and omental adhesions. Cholecystoduodenostomy, using an open mucosal appositional technique for biliary redirection, was performed in each dog. Clinically, results of surgery were good to excellent (ie, lack of postoperative icterus, anorexia, lethargy, or weight loss and absence or infrequency of vomiting). The mean postoperative evaluation period for the 6 dogs was 35 months (range, 20 to 48 months); 5 dogs were alive and healthy at the end of the study. Histologic examination of tissue specimens of the pancreatic mass indicated chronic active fibrosing pancreatitis in the 6 dogs.     

Cholecystography and cholecystoduodenostomy in the diagnosis and treatment of bile duct obstruction in a dog

A common bile duct obstruction was documented in a dog, by performing cholecystography haparoscopic visualization facilitated performance of the cholecystography. Target cells were a consistent hematologic finding. Cholecystoduodenostomy, an easily performed surgical technique, allowed for restoration of bile flow and resolution of clinical signs.     

Tracheal obstruction due to a nodular hyperplastic tracheitis in a dog

A case of a hyperplastic tracheitis of unknown aetiology is recorded. The physical, radiographic, bronchoscopic and histopathological findings are described and discussed.     

Cystadenocarcinoma of the intrahepatic bile duct in a dog

A 14-year-old spayed female Shih-Tzu was referred to the Veterinary Medical Teaching Hospital of Konkuk University for evaluation of an abdominal mass. In diagnostic imaging, two large cystic masses were identified. The affected liver lobes were surgically resected, and the specimens were submitted for histopathological evaluation and immunohistochemical staining. The two cystic lesions were diagnosed as biliary cystadenocarcinoma (BCAC). Recurrence and regional invasion were identified on ultrasonography 36 days postoperatively. The patient died on postoperative day 271. To the best of our knowledge, previously reported case studies of BCAC in dogs presented limited clinical information. In this report, we present a detailed picture comprising a range of clinical information and histopathological examination of BCAC in a dog.     

Traumatic rupture of the common bile duct in a dog

Extrahepatic biliary tract rupture only rarely occur secondary to blunt or sharp trauma to the abdomen. Clinical symptoms result from chemical peritonitis and are unspecific. Recognition most often is delayed from several days to weeks, when patients suffer from ascites, icterus, dehydration and apathy. Surgical therapy depends of the site of laceration. In the present case, a dog with bile peritonitis was presented two weeks after being hit by a car. Explorative celiotomy revealed a rupture of the common bile duct. A cholecystojejunostomy was performed.     

A case of gastrinoma in a Shih-Tzu dog

A five-year-old male Shih-Tzu dog presented with severe vomiting and weight loss. The clinical signs were successfully improved by an eight-day treatment with an H(2)-receptor antagonist, gastrointestinal protectant and antibiotics. Ten days later, however, recurrence of vomiting was seen despite continuous medical treatment. Based on clinical signs and the results of various diagnostic tests including CBC, biochemical analysis, contrast radiography, and endoscopy, a duodenal or pancreatic neoplasm was suspected and exploratory laparotomy was conducted. Some swollen pancreatic regions were found, and biopsy of the pancreas indicated the diagnosis of a gastrin-secreting tumor. Consequently, based on a high serum gastrin level as well as clinical signs and immunohistological findings, we diagnosed the disease as canine gastrinoma, a rare tumor of the pancreas.     

Intestinal obstruction in a dog due to incarceration of small intestine in a coccygeal fracture

A case of dorsal rupture of the abdominal wall with prolapse, incarceration and partial obstruction of small bowel in a 2-year-old dog is reported. The diagnosis was made and confirmed radiographically by an upper gastrointestinal barium study and the defect was corrected surgically. The dog made an uneventful recovery. Résumé. On a rapporté, chez un chien de deux ans, un cas de rupture dorsale de la paroi abdominale avec prolapsus, incarcération et obstruction partielle de l'intestin grêle. Le diagnostic a été fait et confirmé par radiographie au moyen d'une étude de baryum dans la partie supérieure gastro-intestinale et le défaut a été corrigé chirurgicalement. Le chien s'est rétabli normalement. Zusammenfassung. Ein Fall von dorsalem Riss der Bauchdecke mit Prolaps, Inkarzeration und Teilobstruktion des Dünndarms wurde von einem 2-jährigen Hund berichtet. Die Diagnose wurde getroffen und röntgenologisch mit einer ober-gastro-intestinalen Barium Untersuchung bestätigt. Das Gebrechen wurde chirurgisch beseitigt und der Hund erholte sich, ohne weiteren Zwishenfall.     

An unusual clinical presentation of a dog with gastrinoma

Gastrinoma is a rare malignant neuroendocrine neoplasia that results in autonomous gastrin secretion that stimulates hypersecretion of gastric acid, resulting in severe gastric and proximal small intestinal ulcerations. The principal clinical manifestation of gastrinoma is persistent vomiting. This report describes an uncommon manifestation of pancreatic gastrinoma in a dog.     

Traumatic rupture of the bile duct in the dog: a report of seven cases

The paper describes the clinical signs, treatment and post-operative management of seven dogs with bile duct rupture, all of which recovered.     

Multimodality characterization of a noncommunicating congenital duodenal duplication cyst causing pyloric outflow obstruction in a young dog

A 10‐month‐old German Shepherd Dog presented for evaluation of intermittent vomiting. Abdominal radiographs revealed a marked right cranial mass effect. Initial differentials included abscess/cyst or less likely neoplasia from undetermined origin. On abdominal ultrasound the mass appeared cystic and thin walled. Computed tomography revealed a large cystic lesion originating from the pyloroduodenal junction causing pyloric outflow obstruction. A noncommunicating duodenal duplication cyst was found on exploratory laparotomy and further confirmed with histopathology and immunohistochemistry. Enteric duplication cyst should be considered as a differential in young dogs with gastrointestinal signs and a cystic abdominal mass detected with different imaging modalities.     

Hemorrhagic bile pleuritis and peritonitis secondary to traumatic common bile duct rupture,diaphragmatic tear,and rupture of the spleen in a dog

Objective– To describe the diagnosis and successful treatment of bile pleuritis and peritonitis secondary to traumatic rupture of the common bile duct and a diaphragmatic tear in a young dog. Case Summary– A 1‐year‐old German Shepherd dog was referred for evaluation of vomiting and icterus 4 days after being hit by a car. Thoracic radiographs, thoracic and abdominal ultrasonographic examinations, thoraco‐ and abdominocentesis, and positive contrast celiogram indicated hemorrhagic pleuritis and peritonitis, left dorsal diaphragmatic tear, and rupture and infarct of the spleen. Surgical exploration of the abdomen confirmed these findings in addition to a circumferential tear of the common bile duct, leading to a diagnosis of hemorrhagic bile pleuritis and peritonitis. Aerobic and anaerobic bacterial culture of the abdominal fluid yielded no growth. Surgical correction of the traumatic injuries was achieved via common bile duct anastomosis, cholecystojejunostomy, repair of the diaphragm, and splenectomy. The dog developed postoperative signs consistent with aspiration pneumonia but was successfully treated and discharged from the hospital. Clinical signs and laboratory abnormalities resolved and the dog was alive and healthy 8 months after discharge. New or Unique Information Provided– Bile pleuritis is rare in dogs and cats and is usually associated with penetrating, not blunt, abdominal trauma. Multiple organ injury in cases of traumatic bile duct rupture is uncommon; in this dog, rupture of the common bile duct was accompanied by rupture of the diaphragm and spleen.     

Parotid duct sialolithiasis in a dog

Computed tomography was used to evaluate a 7-year-old English bulldog with a history of facial swelling and to aid in the diagnosis of parotid duct sialolithiasis. Removal of the sialolith with repair of the duct was not possible because of ductal fibrosis. Histological evaluation revealed glandular atrophy and fibrosis with lymphoplasmacytic inflammation. The parotid duct was ulcerated and fibrotic, with a mixed inflammatory infiltrate. Surgical excision of the parotid duct and salivary gland was curative.
