Open Pancreatic Stenting with Duct-To-Mucosa Anastomosis for Pancreatic-Duct Obstruction after Pancreaticoduodenectomy with Pancreaticogastrostomy

Pancreatic-duct dilatation is frequently observed in the patients who have undergone pancreaticoduodenectomy (PD). Pancreaticodigestive anastomotic stricture may occasionally develop after PD. Stenosis of the pancreaticoenterostomy induces obstructive chronic pancreatitis, which occurs due to primary stenosis or obstruction of the main pancreatic duct and causes in inflammation of the distal pancreas. The patency of the pancreaticoenterostomy is one of the most important factors affecting the functioning of the remnant pancreas and the quality of life. Endoscopic dilatation is one of the treatment options for stenosis of pancreaticogastrostomy (PG). However, the failure of endoscopic dilatation necessitates surgical approaches. We have described our technique of open pancreatic stenting with a duct-to-mucosa anastomosis for a case which the stenosis of PG could not be resolved by endoscopic dilatation. This technique dose not require re-resected PG or side-to-side pancreaticojejunostomy: the risk of anastomotic leakage is quite low and the procedure is minimally invasive.
