“…Three major factors that should influence the decision: the experience in CBD explora on the availability of endoscopic retrograde cholangiopancreatography, which the surgeon would use postopera vely, and the size of the stones, which indicates if they must be removed or are likely to come out on their own. The short hospital stay can be assumed to indicate the early resump on of normal ac vi es; three of the surgical groups reported that 6963 (85 percent) of 8192 pa ents who underwent LESC returned to full me employment within 7 23 days a er the surgery. The large number of laparoscopic cholecystectomies being performed within the frame work of this study suggests that LESC may be a more popular alterna ve to 3PLC surgery and 24 more than 4PLC.…”

Introduction: Laparoscopic Cholecystectomy is a standard operative procedure for patients with gallbladder diseases and is the most common laparoscopic procedure performed worldwide. The aim of this study is to analyze the different methods of laparoscopic cholecystectomies done by a single surgeon at Nobel Medical College Teaching Hospital. Objectives: The objective and aim of this study are comparing 4 port classic Laparoscopic Cholecystectomy (4PLC), 3 port (3PLC) and Laparo-Endoscopic Single-Site Cholecystectomy (LESC) performed by a single surgeon and correlate worldwide experience with outcomes in our institution. Methodology: The study includes retrospective analysis of 8192 patients who underwent elective laparoscopic Cholecystectomy (LC) from October 2010 to July 2020 performed by the single surgeon. All cases divided into 3 groups depending on the type of LC (4PLC, 3PLC, LESC). The data included the type of the surgery, gender, age, operative time, conversion and complication rate and duration of hospital stay. Results: The hospital stays, operation time and conversion rate decreased from group I to group III. Female patients out numbered the male ones (M:F=1:4). The hospital stays (3.4 days), operation time (35 min), conversion (0.4%) and complications (0.7%) rate decreased from Group of 4PLC to Group of LESC (1.5 days, 13 min, 0.1% conversion, 0.4% complication respectively) which is true for almost all other similar studies. Conclusion: The advantages of LESC include a better cosmetic effect and reduced chance of infections. It has been postulated to be superior in scarless surgery with added benefits of lower pain level and reduced need for analgesics, shorter hospital stays, quicker return to work and lower financial expenses.

This paper reports on the performance evaluation of a novel latching-type electromagnetic actuator which is designed to be embedded at selected joints along single-port laparoscopic surgical instruments (SLS). The aim of this actuator is to allow these instruments to become articulated with a push of a button in order to provide the optimum angulation required during SLS operations. This new actuator is comprised of electromagnetic coil elements, soft magnetic frames and a permanent magnet. Unlike conventional electromagnetic actuators, latching-type electromagnetic actuators could maintain their positions at either end of the actuation stroke without any power application requirement. In the current design, magnetic attraction forces initiated between the permanent magnet and the magnetic frame are utilised to lock the position of the actuator whilst a certain angulation position of the actuator is achieved as a result of the magnetic repulsion forces established between the permanent magnet and the coil elements. The performance of the new actuator in terms of the output force, maximum angulation and patient's safety, was evaluated experimentally and the results were found to compare well with those acquired numerically using finite element methods. This actuator was seen to exhibit sufficient actuation forces and hence, it was capable of providing adaptable angulation characteristics for SLS tools. Finally, thermal evaluation of the actuator's operation was conducted, which was found to be within safety limits specified by clinicians.
