Treatment of the Pancreatic Stump With Neoprene®-Based Glue After High-risk Pancreatoduodenectomy

Postoperative Complications Clinical Trial

Official title: Efficacy and Safety of Exocrine Pancreatectomy With Neoprene®-Based Glue After High-risk Pancreatoduodenectomy (PD) in Patients With Pancreatic, Papilla, Duodenal, and Distal Choledochus Neoplasm

Status Completed

Clinical Trial Summary

The study evaluates the safety and efficacy of Neoprene-based glue in the management of pancreatic stump after pancreatoduodenectomy (PD) in patients at high risk for pancreatic fistula and early neoplastic recurrence, compared with a population of patients at conventional risk.

Clinical Trial Description

Although improved in many aspects, the PD intervention is still burdened by a significant morbidity, related above all to the delicate phase following the removal of the tumor which involves the reconstruction of the gastro-enteric, biliary and especially pancreatic pathway. Among the many variants of the reconstructive phase, that of pancreato-jejunal anastomosis is the one burdened by the highest complication rate (quantified around 40%, with a percentage of pancreatic fistula between 5% and 35%).

In cases at risk of pancreatic fistula it is possible not to perform a conventional pancreato-jejunal anastomosis, but to decide to inject into the pancreatic stump the solidifying glues with the aim of inducing a chemical pancreatectomy of the exocrine component of the pancreas.

Neoprene® (Polychloroprene) has the property of polymerizing and solidifying in an environment with a pH lower than its own (pH <12).

After a systematic review of the sporadic experiences of chemical pancreatectomy published until today, due to the increased complexity of the surgical cases of patients undergoing PD, the investigators have undertaken a formal, single-center prospective study, aimed at clarifying the safety and efficacy data of a Neoprene®-based glue in patients selected through objective criteria (such as the high risk of pancreatic fistula and early tumor recovery after pancreatoduodenectomy).

In this study is expected the prospective collection of a cohort of patients with tumor of the head of the pancreas, papilla, duodenum and distal choledochus to undergo pancreatoduodenectomy (PD) at high risk of pancreatic fistula and / or local recurrence ("Study Arm").

At the same time a second cohort of patients with the same type of neoplasia will be collected, subjected to PD intervention in which however it will be possible to proceed with pancreato-jejunal anastomosis. This group will be defined as "Control Arm".

The first cohort will be the group of patients in which to detect the safety and efficacy of the treatment with Neoprene®-based glue.

The second cohort will be the comparative control group against which patients treated with Neoprene®-based glue can be compared in the hypothesis that peri-operative morbidity,mortality and short and long-term side effects of the intervention are equivalent. ;
