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…
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…
The learning curve, accuracy, and interobserver agreement of endoscope-based confocal laser endomicroscopy for the differentiation of colorectal lesi…
2012
Background: The endoscope-based confocal laser endomicroscopy (eCLE) system allows in vivo imaging of colorectal epithelium. Little is known about the learning curve for accurate interpretation of confocal images acquired with eCLE. Objective: To determine the learning curve of eCLE, its diagnostic accuracy, and the intra- and interobserver agreement for the differentiation of colorectal lesions. Design: Post hoc assessment of selected eCLE images. Setting: Academic centers. Patients: This study involved colonoscopic images from 47 patients. Main Outcome Measurements: Learning curve of eCLE, accuracy, and intraobserver and interobserver agreement. Methods: Three endoscopists received a shor…
Facilitation of Health Professionals Responsible Autonomy with Easy-to-Use Hospital Data Querying Language
2018
Support for the development of responsible autonomy as opposite to management that is based on direct control is found to be by far more effective approach in healthcare management, especially when it concerns physicians as the most influential group of health professionals. It is therefore important to obtain a process-oriented knowledge system where physicians would be able to autonomously answer questions which are outside the scope of pre-made direct control reports. However, the ad-hoc data querying process is slow and error-prone due to inability of health professionals to access data directly without involving IT experts. The problem lies in the complexity of means used to query data…
Self-service Ad-hoc Querying Using Controlled Natural Language
2016
The ad-hoc querying process is slow and error prone due to inability of business experts of accessing data directly without involving IT experts. The problem lies in complexity of means used to query data. We propose a new natural language- and semistar ontology-based ad-hoc querying approach which lowers the steep learning curve required to be able to query data. The proposed approach would significantly shorten the time needed to master the ad-hoc querying and to gain the direct access to data by business experts, thus facilitating the decision making process in enterprises, government institutions and other organizations.
Robot Retrofitting by Using LinuxCNC Complemented with Arduino/RaspberryPI
2020
The use of robots for any manufacturing process is present in almost every industry nowadays. Nevertheless, automating the manufacturing process has always been a challenge for every one of them due to costs and complexity of adding this kind of automation. Acquiring robotic equipment in a concentrated market where the vendors have locked-in their clients can be expensive. In addition to this, the development of intern-factory made solutions has a very steep learning curve and it is not easily achievable. Due to these barriers small and medium size players can’t easily jump into this revolution.
Laparoscopic subtotal gastrectomy for the treatment of advanced gastric cancer: a comparison with open procedure at the beginning of the learning cur…
2017
Background: In the last decades, after some initial concern, laparoscopic subtotal gastrectomy (LSG) is gaining popularity also for the treatment of advanced gastric cancer (AGC). The aim of this study is to compare a single surgeon initial experience on LSG and open subtotal gastrectomy in terms of surgical safety and radicality, postoperative recovery and midterm oncological outcomes. Methods: a case control study was conducted matching the first 13 LSG for AGC with 13 open procedures performed by the same surgeon. Operative and pathological data, postoperative parameters and midterm oncological outcomes were analyzed. Results: There was no significant difference in mortality (0%) and mor…
Adapted Transfer of Distance Measures for Quantitative Structure-Activity Relationships and Data-Driven Selection of Source Datasets
2012
Quantitative structure–activity relationships are regression models relating chemical structure to biological activity. Such models allow to make predictions for toxicologically relevant endpoints, which constitute the target outcomes of experiments. The task is often tackled by instance-based methods, which are all based on the notion of chemical (dis-)similarity. Our starting point is the observation by Raymond and Willett that the two families of chemical distance measures, fingerprint-based and maximum common subgraph-based measures, provide orthogonal information about chemical similarity. This paper presents a novel method for finding suitable combinations of them, called adapted tran…
Laparoscopic distal pancreatectomy: what factors are related to the learning curve?
2014
none 7 no PURPOSE: The factors related to the learning curve for laparoscopic distal pancreatectomy have rarely been evaluated. METHODS: A retrospective study of 32 patients who underwent a laparoscopic distal pancreatectomy performed at a high-volume center by a single pancreatic surgeon experienced with laparoscopic surgery was conducted. Pre-, intra- and postoperative data were collected. The primary endpoint was the length of the operation. The secondary endpoints were the conversion and reoperation rates, overall postoperative morbidity and mortality rates, the length of hospital stay and rate of unplanned splenectomy. RESULTS: The length of the operation and the cumulative sum of the …
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.
