Peritonitis following intestinal anastomosis and enteroplication in a kitten with intussusception.

A 10 week old kitten with an intussusception was treated by intestinal resection and enteroplication. Several months later it developed peritonitis which responded to open peritoneal drainage and antibiotics.     

Chronic mesenteric volvulus in a dog

A chronic, partial mesenteric volvulus was found on laparotomy of an adult Bernese mountain dog with a 4-month history of intermittent vomiting, diarrhea, and weight loss. The dog had elevated cholestatic and hepatocellular leakage enzymes, increased bile acids, azotemia, isosthenuria, and a hypokalemic, hypochloremic, metabolic alkalosis. The dog recovered fully following reduction of the volvulus.     

Recurring gastric volvulus in a dog

A successful prophylactic permanent gastropexy was performed on a dog that had previously experienced four gastric volvulus procedures, one prophylactic pyloroplasty, and two subsequent gastric volvulus repairs. Radiographic evaluation of the previous pyloroplasty and the final permanent gastropexy are illustrated.     

Mesenteric and gastric volvulus in a dog

Concomitant gastric and mesenteric volvulus was diagnosed in a 5-year-old Komondorok. Despite surgical correction of both displacements, the dog died 14 hours after surgery. Although gastric volvulus is a well-known syndrome in dogs, mesenteric volvulus has been reported infrequently. This report illustrates the importance of radiography in cases of suspected gastric volvulus to rule out other potential causes of acute abdominal distention, including mesenteric volvulus.     

Gastroduodenal intussusception in a young dog

A 21-month-old German shepherd crossbreed presented with a nine-month history of intermittent vomiting, anorexia and melaena interspersed with periods of clinical normality. Investigations suggested recurrent pancreatitis and the vomiting resolved with supportive therapy but recurred two weeks later. Abdominal radiographs revealed evidence of an intermittent abdominal mass which, on uitrasonography, had the typical appearance of an intussusception. At laparotomy, a gastroduodenal intussusception was found obstructing the pancreatic and bile duct outflows with perforation of the duodenal wail. The dog was euthanased. Postmortem examination and histology showed no obvious cause for the intussusception but confirmed pancreatic involvement. This is believed to be the first case of gastroduodenal intussusception reported in an animal.     

Incomplete tracheal intussusception in a dog

An 18-year-old male miniature poodle had a chronic nonproductive cough. On radiographic examination, an opacification resembling a foreign body was noticed within the trachea at the level of the sixth cervical vertebra. When the trachea was examined endoscopically, a circumferential flap-like lesion was found. To differentiate the invagination from an annular mass, thoracic computed tomography (CT) of the trachea was performed. There was cranial displacement and invagination of a tracheal segment creating the flap-like lesion. Tracheal intussusception should be considered as a cause of an annular tracheal mass.     

Ileocecocolic volvulus in a German shepherd dog

This report describes an ileocecocolic volvulus in a German shepherd dog with risk factors of previous abdominal surgeries and concurrent chronic enteropathy. Contrast-enhanced computed tomography (CT) with multiplanar reformatting was more sensitive than abdominal radiographs or ultrasound to obtain a diagnosis, because of the presence of a “whirl-sign” on CT. A combination of colopexy and cecopexy was succesfully used to treat the patient’s condition.     

Gastroesophageal intussusception in a young German shepherd dog

A gastro-oesophageal intussusception in a female, six-week-old German shepherd dog was treated surgically with success. The dog was presented with acute dyspnoea and signs of shock. After laparotomy, the herniated organs were reduced from the lumen of the oesophagus into the abdomen and an imbrication of the oesophageal hiatus, an appositional fundoplica-tion and a left-sided incisional fundopexy were performed. The dog made an uneventful recovery. Eighteen months after surgery the dog is still alive, with no clinical signs despite the persistent presence of megaoesophagus.     

Gastric dilatation and volvulus in a brachycephalic dog with hiatal hernia

A brachycephalic dog was presented with an acute onset of retching and abdominal discomfort. The dog had a chronic history of stertor and exercise intolerance suggestive of brachycephalic airway obstructive syndrome. Radiographs were consistent with a Type II hiatal hernia. The dog was referred and within hours of admission became acutely painful and developed tympanic abdominal distension. A right lateral abdominal radiograph confirmed gastric dilatation and volvulus with herniation of the pylorus through the hiatus. An emergency exploratory coeliotomy was performed, during which the stomach was derotated, and an incisional gastropexy, herniorrhaphy and splenectomy were performed. A staphylectomy was performed immediately following the exploratory coeliotomy. The dog recovered uneventfully. Gastric dilatation and volvulus is a potentially life‐threatening complication that can occur in dogs with Type II hiatal hernia and should be considered a surgical emergency .     

一犬场幼犬频发肠套叠的诊治

肠套叠是指部分肠管及其肠系膜套入邻近肠腔所致的一种绞窄性肠梗阻,是幼犬常见的急腹症之一。2005年四川省某犬养殖场繁殖的幼犬在2～3月龄时频繁发生肠套叠,发病率高达14.5%,治愈率极低,造成了较大的经济损失。     

Pylorogastric intussusception in the dog: a case report and literature review

A 10-month-old, neutered male Saint Bernard presented for evaluation of acute, severe vomiting. A soft-tissue mass was noted within the stomach on survey abdominal radiographs. The diagnosis of pylorogastric intussusception was made during exploratory celiotomy. The intussusception was manually reduced at surgery, the pyloric antrum was enlarged, and the duodenum was permanently affixed to the abdominal wall in an attempt to prevent recurrence of the intussusception. The dog recovered, has gained weight (5 kg), and has had only one isolated episode of vomiting during the one year since discharge from the hospital. This report documents the fourth reported case of pylorogastric (i.e., duodenogastric, gastrogastric) intussusception in the veterinary literature and is the first report that details the surgical management of the disease.     

Aortic thromboembolism as a complication of gastric dilatation/volvulus in a dog

An unusual complication of gastric dilatation/volvulus developed in a 10-year-old spayed Great Dane. An aortic thromboembolus lodged in the iliac artery bifurcation 4 days after admission and tube gastropexy to correct the condition. The dog was euthanatized after 48 hours of supportive care failed to elicit any improvement. Thrombus formation appeared to originate in the left ventricle; however, a primary cause could not be determined.     

Gastro–oesophageal intussusception in an adult dog

A case of oesophageal intussusception of the stomach in a 9–year–old 351b cross–bred male dog is reported. This condition has previously been recorded only in young animals, often in the first few weeks of life. The history and post mortem findings are described, the aetiology is discussed and the literature briefly reviewed.     

Mesenteric volvulus in the dog: a retrospective study of 12 cases

Mesenteric volvulus was diagnosed in 12 dogs over a nine-year period. Each case was presented with abdominal distension and shock. Haematochezia, which is frequently reported in association with mesenteric volvulus, was present in only two of the dogs. The diagnosis, which in all cases was based on radiography, was followed by immediate treatment for shock and surgical intervention whenever possible. In five of the 12 cases, the volvulus was treated successfully and these patients survived. This indicates that the prognosis for mesenteric volvulus might be better than is currently believed, and immediate laparotomy is recommended if mesenteric volvulus is suspected.     

Torsion and volvulus of the transverse and descending colon in a German shepherd dog

A German shepherd dog was presented two months after surgery for correction of acute gastric dilatation volvulus. The dog had been diagnosed with exocrine pancreatic insufficiency. Radiographs revealed marked gaseous distension of one loop of intestine with a generalised increase in intestinal gas content. A 360 degrees anticlockwise rotation of the descending and transverse colon, around the longitudinal axis of the mesocolon, was diagnosed at exploratory coeliotomy. The transverse and descending colon appeared uniformly necrotic and an end-to-end colo-colic resection and anastomosis was performed. The dog initially made satisfactory postoperative progress but was euthanased on the third postoperative day after it developed an intestinal intussusception.
