Trial Outcomes & Findings for Reinforced Staple Line on Leak Rate in Distal Pancreatectomy (NCT NCT01359410)

NCT ID: NCT01359410

Last Updated: 2017-05-10

Results Overview

* Identified as being a grade B or grade C fistula or any fistula that altered the patients' management in any way * Determination of severity of pancreatic fistula was done using the ISGPF(International Study Group Pancreatic Fistula) leak/fistula/pancreatic occlusion failure * Grade B: \>3x normal serum amylase, often well clinical condition, yes/no specific treatment, negative/positive ultrasound/CT, usually persistent drainage (\>3 weeks), yes/no signs of infection, yes/no readmission, no sepsis, no reoperation, no death related to fistula * Grade C: \>3x normal serum amylase, ill appearing/bad, requires specific treatment, positive ultrasound/CT, persistent drainage (\>3 weeks), signs of infection, yes/no readmission, sepsis, reoperation, and death related to fistula
