Change from Hybrid to Fully Minimally Invasive and Robotic Esophagectomy is Possible without Compromises.

2018

Background The incidence of esophageal carcinoma is increasing in the western world, and esophageal resection is the essential therapy. Several studies report advantages of minimally invasive esophagectomies (MIEs) versus conventional open procedures (OPs). The benefits of the use of fully MIE or robot-assisted MIE (RAMIE) compared with the hybrid approaches (laparoscopic gastric preparation and open transthoracic esophagectomy) remain unclear. Methods Between July 2015 and August 2017, the data of 75 patients with esophageal carcinoma were prospectively registered. Of the 75 patients, 25 treated with a hybrid MIE (hybrid), 25 with total MIE (MIE), and 25 with RAMIE. All patients were oper…

Comparative Study of the Initial Experience in Performing Robotic and Laparoscopic Right Hepatectomy with Technical Description of the Robotic Techni…

2017

<b><i>Background:</i></b> Despite potential benefits of robotic liver surgery, it is still considered a “development in progress” technique. <b><i>Methods:</i></b> The outcomes of 14 patients undergoing robotic right hepatectomy were analyzed and compared with the results of 20 laparoscopic right hepatectomies consecutively performed by the same young surgeon. <b><i>Results:</i></b> The overall mean operative time was less in robotic arm (425 ± 139 vs. 565.18 ± 183.73, <i>p</i> = 0.022) and the estimated blood loss was similar (335.15 ± 139.8 vs. 423.95 ± 205.15, <i>p</i> = 0.17); no blood transf…

Robotic Pancreaticoduodenectomy: Technical Considerations

2017

Robotic surgery can help to overcome some technical limitations of laparoscopic pancreaticoduodenectomy thanks to EndoWrist instrumentations and the 3D view. Despite the potential benefits, its employment is still low and controversial. We focused on some important technical details crucial for a safe robotic pancreatectomy. After performing 52 robotic pancreatic resections that included 10 pancreatoduodenectomies, the authors describe their technique. The review of literature on robotic and laparoscopic duodenopancreatectomy is also performed in order to evaluate possible benefits of the robotic platform. We describe the step-by-step surgical procedure, analyzing all possible troubleshooti…

A DGS gesture dictionary for modelling on mobile devices

2017

ABSTRACTInteractive or Dynamic Geometry System (DGS) is a tool that help to teach and learn geometry using a computer-based interactive environment. Traditionally, the interaction with DGS is based on keyboard and mouse events where the functionalities are accessed using a menu of icons. Nevertheless, recent findings suggest that such a traditional model of interaction has a steep learning curve and is inadequate to develop DGS for devices with multi-touch screens. Thus, we propose a new interaction model for DGS based on a gesture dictionary which enables the construction and manipulation of geometric objects without the need of accessing a menu of icons. The dictionary is divided into thr…

Learning Curve in Surgical Treatment of Odontoid Fixation for a Series of Type II C2 Fractures

2019

The craniovertebral junction (CVJ) is a complex anatomical area upon which most of the motion of the upper cervical spine depends [1]. Because of its unique range of motion, the CVJ is subject to several types of traumatic injury; it has been shown that odontoid fractures are the most common ones in the general population and are the most common isolated spinal fractures [2]. Accounting for up to 18% of all cervical fractures, odontoid fractures are the most common ones in elderly patients [3], in whom they account for up to 60% of spinal cord injuries [4].

Position Paper on Young Vascular Surgeons Training of the Mediterranean Federation for the Advancing of Vascular Surgery (MeFAVS): State of the Art a…

2021

ABSTRACT The Mediterranean Federation for the Advancing of Vascular Surgery (MeFAVS) was founded in 2018, with the aim to promote cooperation among vascular professionals within Mediterranean countries. Due to its prominent social and economic impact on national health systems, diabetic peripheral artery was selected as the very first topic to be investigated by the federation. In this second paper, different experiences from delegates of participating countries were shared to define common strategies to harmonize, standardize, and optimize education and training in the Vascular Surgery specialty.

A structured training pathway to implement robot-assisted minimally invasive esophagectomy: the learning curve results from a high-volume center

2019

ABSTRACTTo ensure safe implementation of robot-assisted minimally invasive esophagectomy (RAMIE), the learning process should be optimized. This study aimed to report the results of a surgeon who implemented RAMIE in a German high-volume center by following a tailored and structured training pathway that involved proctoring. Consecutive patients who underwent RAMIE during the course of the program were included from a prospective database. A single surgeon, who had prior experience in conventional MIE, performed all RAMIE procedures. Cumulative sum (CUSUM) learning curves were plotted for the thoracic operating time and intraoperative blood loss. Perioperative outcomes were compared between…

A sequence of flaps and dissection exercises in the living model to improve the learning curve for perforator flap surgery.

2020

Abstract Introduction The training to learn how to perform perforator flaps requires practice on a living model to optimize dissection and to evaluate outcome. The purpose of this study was to describe a training model that optimizes the use of animals in order to perform the maximum number of exercises per animal. Material and methods The sequence has been planned and practiced by the first and last author, recorded perfected and implemented in a two-day surgical course. The sequence was then evaluated by the trainers and the trainees by means of a questionnaire. Results All students were able to complete the sequence of exercises before the end of the second day except two (8/10) who coul…
