Urograffin had been used to opacify the bile and the pancreatic duct
. For the current study, successful stent retrieval was defined as complete removal of stent or where the distal tip of the stent was left in the duodenum.7 Proximal CBD migration was defined as when the lower end of the migrated stent was present above the cystic duct in the CBD.
[ClickPress, Mon Jul 15 2019] Biliary and pancreatic stents have been used to establish patency of a pancreatic duct
or obstructed bile.
Intraductal solid tumor within the main (n=7) or branch (n=1) pancreatic duct
was detected in 62.5% of cases with CT (5 of 8), 71.4% with MRCP (5 of 7), and 100% with EUS (7 of 7).
Gross examination of the surgical specimen revealed a 115/70 mm pancreatic mass, firm, relatively well-circumscribed, located in the cephalic zone with intraluminal extension into the dilated main pancreatic duct
towards ampullary region; thus, the major duodenal papilla was still permeable.
After 12 weeks of conservative management, the patient underwent pancreatic duct
stenting for his disconnected duct syndrome.
PJBSID was first applied by us in a patient with complete disruption of pancreaticojejunal anastomosis after pancreaticoduodenectomy in June 2006, and this use of internal drainage through the main pancreatic duct
led to the patient having an unexpectedly smooth postoperative recovery.
An additional 4, 6, or 7cm long 5FrGeenenA(r) pancreatic plastic stent (Cook Medical) was placed in all cases where pancreatic duct
was accidentally cannulated.
MCN does not usually communicate with the pancreatic duct
. (18) MCN is typically a solitary lesion, so if additional cystic pancreatic lesions are present, intraductal papillary mucinous neoplasm or pseudocyst should be considered as an alternative diagnosis.
We hypothesize that cholesterol polyps in our patient acted like gallstones and caused temporary obstruction of the pancreatic duct
leading to pancreatitis.
Based on the numerous studies into the biology of pancreatic ductal adenocarcinoma, it has been proved that it develops due to cancerous transformation of epithelial cells in pancreatic ducts
. In this process, numerous mutations of suppressive genes and oncogenes transform the normal non-mucinous, cuboidal epithelium lining up the pancreatic ducts
into noninvasive, cancerous cylindrical epithelial cells possessing the ability to produce mucus .
(1) Intraductal tubulopapillary neoplasm shows solid and nodular masses occluding the pancreatic duct
without mucin production, whereas IPMN shows polypoid tumors as mural nodules intruding into dilated duct with prominent cystic changes and visible mucin.
2) closure of remnant pancreatic stump with continuous suture after pancreatic duct
ligation: following transection of the pancreas, the orifice of the pancreatic duct
was ligated with non-absorbable 4-0 polypropylene suture, and pancreatic remnant stump was closed with continuous oversewing non-absorbable 2-0 polypropylene or absorbable 2-0 polyglactin suture.
