Postoperative Bleeding After the Modified Frey Procedure With Laparoscopic Distal Pancreatectomy for a Hemorrhagic Pancreatic Pseudocyst: A Case Report
Abstract
We report a case of a hemorrhagic pancreatic pseudocyst (PPC) in which a laparoscopic distal pancreatectomy and modified Frey procedure were performed. These procedures resulted in postoperative bleeding from a small hole in the pancreatic duct wall, caused by the removal of a pancreatic duct stone. A 76-year-old man had been undergoing follow-up treatment for six years for alcoholic chronic pancreatitis (CP). While the main pancreatic duct had gradually dilated, and its intraluminal stones had increased in number and size, a PPC had appeared and enlarged gradually at the distal end of the pancreatic tail. During a periodic follow-up, an abdominal computed tomography (CT) scan showed a new, small PPC at the duodenal side of the original, containing a hemorrhagic pseudoaneurysm. Abdominal angiography showed extravasation into the small PPC from arterial branches of the great pancreatic artery, which were subsequently embolized. Nine days after the arterial embolization, a modified Frey procedure with a laparoscopic distal pancreatectomy was performed. The postoperative course was uneventful until 13 days after the operation, when the patient exhibited epigastralgia and melena. An abdominal CT scan revealed hemorrhagic dilatation of the cavity of the longitudinal pancreaticojejunostomy, without pseudoaneurysms or active bleeding. Surgical exploration revealed arterial bleeding from a small hole in the pancreatic duct wall, which had been created during the removal of a…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
