Laparoscopic Partial Nephrectomy with a Remotely Activated Bulldog Clamp in a Pig Model

Abstract

The newly designed device can remotely control the renal artery, which made clamping and unclamping much easier. It is effective and safe in LPN.

Use of hemostatic agents for surgical bleeding in laparoscopic partial nephrectomy: Biomaterials perspective

“…However, this technique is time consuming and requires experience and expertise, since an accurate tumor excision followed by an efficient wound closure in a time‐controlled manner (due to the limited warm ischemia time) is a demanding task (Breda et al, 2007; Kane et al, 2004). It is well established that when the warm ischemia time exceed 30 min, and irreversible renal damage occurs (Chen, Guo, Hou, & Wang, 2017; Porpiglia et al, 2007). In fact, the warm ischemia time during LPN is in the range of 27–44 min (an average of 35 min), so avoiding or saving ischemia time is an effort that is worth investigating (Chen et al, 2017).…”

Several alternatives have been exploited both to avoid hilar occlusion in cases of small renal lesions and, when hilar occlusion cannot be avoided, to provide an additional help, reducing the time and difficulty of the procedure.…”

“…Several alternatives have been exploited both to avoid hilar occlusion in cases of small renal lesions and, when hilar occlusion cannot be avoided, to provide an additional help, reducing the time and difficulty of the procedure. Chen and his team developed a new technology that allows the control and monitoring of clamping pressure from the outside of the body and proved a reduction of the warm ischemia time in pig model (Chen et al, 2017).…”
