A double-cannula pancreatic gastrostomy method for pancreatic duct stenosis due to disconnected pancreatic duct syndrome: A surgical case report

INTRODUCTION AND IMPORTANCE: Disconnected Pancreatic Duct Syndrome (DPDS) without peripancreatic fluid collections are relatively difficult for endoscopists to manage and usually treated with distal pancreatectomy or pancreaticojejunostomy. However, these procedures are risky for patients with severe edema of pancreatic tissue. We report an original one-stage surgical approach for these patients, namely, the “double-cannula pancreatic gastrostomy method”. CASE PRESENTATION: A 38-year-old man was admitted with recurrent acute pancreatitis. ct images suggest pancreatic duct discontinuity syndrome. Intraoperative exploration revealed that pancreas inflammation was severe and distal pancreatectomy or pancreaticojejunostomy were risky. Therefore, we decided to perform a double-cannula pancreatic gastrostomy. A 16F type catheter penetrated the front and back walls of the stomach for gastrostomy, and a 6F catheter was inserted into the pancreatic duct for drainage. We placed the drainage tube of pancreatic duct into the gastrostomy tube to ensure the drainage tube of pancreatic duct could reach the gastric cavity. The gastrostomy tube is led out of the body through the abdominal wall. CLINICAL DISCUSSION: Both endoscopic and surgical approaches have been reported in treating DPDS patients. Internal drainage and excision are common surgical methods. CONCLUSIONS: The double-cannula pancreatic gastrostomy was a safe and effective method in this patient. CORE TIP: In this case, the patient suffered recurrent acute pancreatitis due to disconnected pancreatic duct syndrome. This patient without peripancreatic fluid collections was relatively difficult for endoscopists to manage. However, intraoperative exploration revealed a high risk of distal pancreatectomy or pancreaticojejunostomy. Therefore, we used A double-cannula pancreatic gastrostomy method and successfully treated the complications of pancreatic duct stenosis.
