A Virtual Counseling Application Using Artificial Intelligence for Communication Skills Training in Nursing Education: Development Study.

Journal of medical Internet research·2019

This study introduces an integrated device for radiofrequency (RF) liver resection, improving avascular plane estimation and minimizing RF energy use. This innovation reduces blood loss and liver damage during surgery.

Area of Science:

  • Surgical Innovation
  • Minimally Invasive Surgery
  • Hepatobiliary Surgery

Background:

  • Radiofrequency (RF) energy ablation can minimize blood loss during liver resection.
  • Estimating avascular plane depth and controlling RF energy application are challenges, potentially leading to overtreatment and damage.

Purpose of the Study:

  • To evaluate a novel integrated device for simultaneous ablation and division during laparoscopic liver resection.
  • To determine the feasibility and applicability of this integrated model in a porcine model.

Main Methods:

  • Laparoscopic liver resection was performed on a live porcine model.
  • The study utilized a new device integrating ablation and division functionalities.

Main Results:

  • The integrated device facilitated uncomplicated liver resections with minimal intraoperative blood loss.
  • The device effectively resolved challenges in estimating avascular plane depth post-coagulation.
  • A real-time feedback mechanism minimized unnecessary RF energy application, reducing collateral liver damage.

Conclusions:

  • The proposed integrated device is functionally acceptable for liver resection.
  • This model offers a potential method for accurately determining avascular plane depth and required RF energy during liver resection.
