Tissue Adhesive Glue Modified Cyanoacrylate (Glubran® 2) in Soft Pancreas

Официальное название

Pancreaticojejunostomy With or Without Modified N-butyl-2-cyanoacrylate Following Pancreaticoduodenectomy in Soft Pancreas: Randomized Controlled Trial

Обзор

This is a single-center, randomized controlled trial comparing the efficacy of pancreaticojejunostomy with modified N-butyl-2-cyanoacrylate(Glubran® 2) versus standard pancreaticojejunostomy without cyanoacrylate in preventing postoperative pancreatic fistula (POPF) in patients undergoing pancreaticoduodenectomy with soft pancreatic texture. The primary endpoint is the incidence of postoperative pancreatic fistula at 30 days post-surgery, as defined by the International Study Group on Pancreatic Fistula (ISGPF) criteria.Secondary outcomes include surgical complications and length of hospital stay. The study will enroll approximately 194 patients at a single center.

Подробное описание

Postoperative pancreatic fistula (POPF) remains the most common and serious complication following pancreaticoduodenectomy, with incidence rates reaching up to 56.7% in patients with soft pancreatic texture. The soft pancreatic parenchyma is particularly vulnerable to anastomotic breakdown due to its friable nature and difficulty in achieving secure suturing.

N-butyl-2-cyanoacrylate is a biodegradable tissue adhesive that polymerizes rapidly upon contact with hydroxide ions in tissue fluids, forming a strong, flexible bond. The application of modified N-butyl-2-cyanoacrylate to pancreaticoenteric anastomoses may reduce the incidence of POPF by providing additional mechanical reinforcement and sealing of minor leaks.

This is a phase III, single-center, prospective, randomized controlled trial with parallel groups. Eligible patients will undergo intraoperative assessment of pancreatic texture (soft confirmed by surgeon's palpation). Randomization will occur intraoperatively after resection but before reconstruction, using computer-generated blocks.

This study aims to evaluate whether the application of modified N-butyl-2-cyanoacrylate (Glubran® 2) during pancreaticojejunostomy can significantly reduce the incidence of POPF in patients with soft pancreatic texture undergoing pancreaticoduodenectomy. Patients will be randomized to receive either standard pancreaticojejunostomy (control group) or pancreaticojejunostomy with modified N-butyl-2-cyanoacrylate application (intervention group).

The intervention group will receive 1-2 mL of modified N-butyl-2-cyanoacrylate applied topically to the pancreatic stump and anastomosis site during pancreaticojejunostomy. The control group will receive standard duct-to-mucosa pancreaticojejunostomy without adhesive. All patients will receive standardized perioperative care, including prophylactic antibiotics and drain management per ISGPF guidelines.

Follow-up will include daily amylase measurements in drains (days 1,3,5), CT imaging if POPF suspected.
