BACKGROUND: Although various devices have been clinically used for laparoscopic liver resection (LLR), the best device for liver parenchymal transection remains unknown. Olympus Corp (Tokyo, Japan) developed a laparoscopic hybrid pencil (LHP) device, which is the first electric knife to combine ultrasound and electric energy with a monopolar output. We aimed to evaluate the feasibility of using the LHP device and to compare it with the laparoscopic monopolar pencil (LMP) and laparoscopic ultrasonic shears (LUS) devices for LLR in a porcine model...

One of the main procedures in intestinal surgery is anastomosis, which is mostly performed by stapling or hand suturing. Due to limitations of these methods, a novel automatic suturing machine was designed and fabricated in this study, equipped with a needle-driving system; a thread control mechanism, and a linear mechanism, which is applicable in intestinal anastomosis by making continuous sutures. The main advantages of the fabricated machine are employing biocompatible suture, from the tissue's adaptation point of view, and making a uniform suturing pattern, independent of surgeon's skill, and thus offering a greater strength than the hand-sutured specimen...

Orthognathic surgery belongs to the scope of maxillofacial surgery. It treats dentofacial deformities consisting in discrepancy between the facial bones (upper and lower jaws). Such impairment affects chewing, talking, and breathing and can ultimately result in the loss of teeth. Orthognathic surgery restores facial harmony and dental occlusion through bone cutting, repositioning, and fixation. However, in routine practice, we face the limitations of conventional tools and the lack of intraoperative assistance...

The implementation of augmented reality (AR) in image-guided surgery (IGS) can improve surgical interventions by presenting the image data directly on the patient at the correct position and in the actual orientation. This approach can resolve the switching focus problem, which occurs in conventional IGS systems when the surgeon has to look away from the operation field to consult the image data on a 2-dimensional screen. The Microsoft HoloLens, a head-mounted AR display, was combined with an optical navigation system to create an AR-based IGS system...

OBJECTIVE: The aim of this study is to examine the experience of European surgeons on autologous fat transfer (AFT) and highlight differences between countries and levels of experience. BACKGROUND DATA: The popularity of AFT causes an increase in sophisticated scientific research and clinical implementation. While results from the former are well-documented, important aspects of the latter are far less recognized. METHODS: An international survey study about surgeon background, besides AFT familiarity, technique, and opinion, was distributed among surgeons from 10 European countries...

Mini-invasive surgery-for example, laparoscopy-has challenged surgeons' skills by extending their usual haptic space and displaying indirect visual feedback through a screen. This may require new mental abilities, including spatial orientation and mental representation. This study aimed to test the effect of cognitive training based on motor imagery (MI) and action observation (AO) on surgical skills. A total of 28 postgraduate residents in surgery took part in our study and were randomly distributed into 1 of the 3 following groups: (1) the basic surgical skill, which is a short 2-day laparoscopic course + MI + AO group; (2) the basic surgical skill group; and (3) the control group...

The advantage of simulation environments is that they present various insights into real situations, where experimental research opportunities are very limited-for example, in endoscopic surgery. These operations require simultaneous use of both hands. For this reason, surgical residents need to develop several motor skills, such as eye-hand coordination and left-right hand coordination. While performing these tasks, the hand condition (dominant, nondominant, both hands) creates different degrees of mental workload, which can be assessed through mental physiological measures-namely, pupil size...

Eugène Louis Doyen (1859-1916) is considered as the reformer of French surgery at the end of 19th and early 20th century. Although he had a short life, dying at the age of 57, he left his mark in the history of French medicine and especially surgery, not only because he introduced many new medical instruments but also for his innovative idea to introduce cinematography in surgical education, which is crucial until today in the education of every surgeon in the world.

INTRODUCTION: A recent development in minimally invasive surgery (MIS) is single-port surgery, where a single large multiport trocar is placed in the umbilicus. All medical schools require that students complete an anatomy course as part of the medical curriculum. However, there is limited instruction regarding the detailed parts of the "umbilicus." In several famous anatomy atlases, the umbilicus is not dissected at all and is merely represented as a button. Until now, the true nature of the umbilicus has not been anatomically demonstrated...
