Cystogastrostomy in the treatment of pancreatic pseudocyst/abscess in two dogs

Abstract

Two dogs with pancreatic pseudocyst or pancreatic abscess formation were treated by transgastric cystogastrostomy. In each case drainage of the cyst/abscess cavity into the stomach was followed by resolution of the primary lesion. One dog succumbed to an E coli bronchopneumonia after infection of the deep venous line used for total parenteral nutrition. The second dog recovered despite requiring additional surgery for biliary obstruction. Both dogs required intensive care during and after the operation.

Pancreatitis

“…A splenectomy may be required at the same time if the splenic artery cannot be preserved (Salisbury et al 1988). Drainage of an unresectable abscess has been established in the stomach or the duodenum (Bellenger et al 1989). Partial pancreatectomy is performed with gentle dissection across the pancreatic parenchyma and ligation of the pancreatic duct.…”

“…Repeated ultrasound-guided aspiration may be required in some cases (Smith & Biller 1998). Drainage of the cyst can be achieved in the duodenum or the stomach if the capsule is thick to prevent leakage (Bellenger et al 1989). In these cases surgical intervention is usually recommended, although surgical techniques are poorly described in veterinary medicine.…”

Pancreatic pseudocyst causing extrahepatic biliary obstruction in a dog

“…Alkaline phosphatase IV Intravenous/ly ALT Alanine aminotransferase MUVH Murdoch University Veterinary Hospital CT Computed tomography PO Per os P ancreatic pseudocysts are a result of pancreatic duct disruption secondary to acute or chronic pancreatitis, or occasionally pancreatic trauma. 1,2 Pancreatic enzymes and necrotic pancreatic tissue collect within or adjacent to the pancreas and become surrounded by inflamed peritoneal, mesenteric or serosal membranes which form a thick fibrous capsule. 3 Pseudocysts are commonly recognised in humans but there are only four reported cases in dogs.…”

“…3 Pseudocysts are commonly recognised in humans but there are only four reported cases in dogs. 2,4,5 In humans, pancreatic pseudocysts are suspected when patients with pancreatitis fail to recover within a week of treatment. 1 The clinical signs of pancreatic pseudocyst are similar in humans and dogs and include persistent vomiting, depression, anorexia, abdominal pain and diarrhoea.…”

“…1 The clinical signs of pancreatic pseudocyst are similar in humans and dogs and include persistent vomiting, depression, anorexia, abdominal pain and diarrhoea. 2,4,5 Jaundice may also result from compression of the common bile duct by the pseudocyst or stricture of the bile duct secondary to chronic pancreatic inflammation and fibrosis. 2,6,7 The cranial position of the pancreas and abdominal guarding due to pain associated with pancreatic pseudocysts can make detection of the mass difficult.…”
