Clinical Outcomes for General Surgery

Clinical Studies

Many clinical studies have been published about Transcollation® technology, a combination of RF energy and saline that provides hemostatic sealing of soft tissue and bone and has been shown to reduce blood transfusion rates during and after general surgery.1 Below are a few key studies and their corresponding results.

Hepatic Resection in 170 Patients Using Saline-cooled Radiofrequency Coagulation1
In a study of 170 patients at the University of Pittsburgh Medical Center, Geller et al. reduced transfusion rates for liver resections to 3.5% when using Transcollation technology compared to published averages of 15-33% for large institutions.

Novel Method of Stump Closure for Distal Pancreatectomy with a 75% Reduction in Pancreatic Fistula Rate2
In a study examining the rate of pancreatic fistula (PF) formation occurring following distal pancreatectomy in 62 patients, those cases that incorporated Transcollation technology experienced a 75% reduction in the PF rate compared to control (10% PF rate in the Transcollation arm vs. 36% PF rate in the control arm).

Open Partial Nephrectomy Using Saline-Enhanced Monopolar Radiofrequency Device: Evaluation of Novel Surgical Technique with TissueLink DS3.0 Dissecting Sealer3
In a study of 22 open partial nephrectomies with hilar occlusion, data showed a 30-35% (p=0.07) reduction in blood loss in the 11 cases treated with Transcollation technology.
