A Comparative Assessment of Novel Mini-Laparoscopic Tools

Background: Mini-laparoscopy, or needlescopy, is an emerging minimally invasive technique that aims to improve on standard laparoscopy in the areas of tissue trauma, pain, and cosmesis. The objective of this study was to determine if there was a difference in functionality between 2 novel mini-laparoscopic instruments when compared to standard laparoscopic tools. Differences were assessed in a simulated surgical environment. Methods: Twenty participants (5 novices, 10 intermediate, 5 expert) were recruited for this institutional review board–approved study in a surgical simulation training center. Group A tools were assembled intracorporeally, and Group B tools were assembled extracorporeally. Using standard laparoscopic graspers, mini-laparoscopic graspers, or a combination of both, each participant performed 3 basic laparoscopic training tasks: a Peg Transfer, Rubber Band Stretch, and Tootsie Roll Unwrapping. Following each round of tasks, participants completed a survey evaluating the mini-laparoscopic...
