Muscle activity and hand motion in veterinarians performing laparoscopic training tasks with a box trainer.

Objective: To evaluate muscle activity and hand motion in veterinarians performing a standard set of laparoscopic training tasks.

Sample: 12 veterinarians with experience performing laparoscopic procedures.

Procedures: Participants were asked to perform peg transfer, coordination, precision cutting, and suturing tasks in a laparoscopic box trainer.

Performance analysis on physical simulator of four different instrument setups in laparo-endoscopic single-site (LESS) surgery.

Background: Over the past decades, minimally invasive surgery has undergone continuous development due to the demand for scarless results, with laparo-endoscopic single-site (LESS) surgery constituting one of today's most favored alternatives. In this study, we aim to assess the relative technical difficulty and performance benefits of dynamic articulating and pre-bent instruments, either combined with conventional laparoscopic tools or not, during the completion of two basic tasks hands-on simulator.

Methods: A total of 20 surgeons were included and performed two basic simulator tasks-coordination and cutting-carried out using four different combinations of LESS-designed and straight conventional laparoscopy instruments.

Ergonomic analysis of muscle activity in the forearm and back muscles during laparoscopic surgery: influence of previous experience and performed task.

Purpose: The first aim of this study is to analyze the muscle activity in back and forearm muscles in surgeons during laparoscopic dissection and suturing maneuvers. The second aim is to determine the influence of the surgeons' previous experience in laparoscopic surgery.

Methods: A total of 30 laparoscopic surgeons were divided in 3 groups: novice suturing, novice dissecting, and experts suturing.

Laparoscopic sonography in the urinary system.

This work reports the use of laparoscopic-transducer sonography for the examination of the urinary system in a swine model. Animals underwent a two-phase study. In the first phase, the urinary system was examined using laparoscopic sonography.
