A major challenge of minimally invasive surgery (MIS), particularly in laparoendoscopic single site (LESS) surgery, is trocar crowding. Trocar crowding causes instruments fencing, limited instrument access and limited endoscope views. It also increases the workload of surgeons. One strategy to alleviate the problem is to use magnetic anchored and guided system (MAGS). Existing MAGS endoscopes are assembled by multiple miniature components and actuated by onboard motors. This makes them complex, difficult to manufacture as well as requires additional power consumption. In this work, we present a novel soft-bodied magnetic anchored and guided endoscope, which comprises of a silicon structure, the magnets and a wireless camera module. The developed endoscope incorporates benefits of both MAGS (e.g. wireless steering and translation) and soft-bodied devices (e.g. compactness, lightweight, safety and simple fabrication). We model the moment loads experienced by the silicon structure to optimize the design of the endoscope. Performance and feasibility of the endoscope are validated using both benchtop setting and animal cadaver.

The field of minimally invasive surgery has evolved rapidly since the first laparoscopic appendectomies and cholecystectomies were performed nearly 30 years ago.1 Minimally invasive approaches are now widely used for gastrointestinal resection, hernia repair, antireflux surgery, bariatric surgery, and solid-organ surgery, such as hepatic, pancreatic, adrenal, and renal resections. Although the techniques and equipment needed to access, expose, and dissect vary according to the type of operation and surgeon’s preference, a basic set of equipment is essential for any laparoscopic or robotic procedure: endoscope, camera, light source, signal processing unit, video monitor, insufflator and gas supply, trocars, and surgical instruments. Understanding how to use and troubleshoot this equipment is critical for any surgeon who performs minimally invasive surgery. We review the essentials of basic laparoscopic equipment, including the mechanics of normally functioning equipment and the various types of laparoscopic trocars and instruments. We also discuss robotic equipment and the fundamental differences from laparoscopy. Minilaparoscopy and single-site equipment are briefly explained. Additionally, we discuss potential technical difficulties that surgeons may encounter while performing minimally invasive procedures and provide suggestions for troubleshooting these problems.

Minimally invasive surgery has changed the landscape of women’s surgical healthcare. Conventional and robotic laparoscopy are the preferred approach for many major minimally invasive gynecological procedures. However, the philosophy of minimally invasive surgery has been pushed to reduce the size and minimize the number of ports placed. Many conventional minimally invasive surgical procedures use 3–5 ports through multiple small incisions. Laparoscopic single site surgery tries to perform on that philosophy but has its limitations. Enters robotic surgery already a major force in minimally invasive surgery and now sets to remove the limitations of single site surgery. However it requires proper understanding of the instruments and the techniques for successful robotic single site surgery. It starts with patient selection. Knowing the instruments needed and the proper set up of those instruments. Then knowing how to use the instruments in operating and suturing and closing. And finish with special considerations.

Abstract Background Risk of surgery is among the highest-rated concerns among Crohn’s disease (CD) patients. Quality of life is often worsened by intestinal surgery. This study aimed to assess the possible predictors of long-term quality of life after minimally invasive surgery for ileal, colonic or ileocolonic CD. Methods Data of all the 72 consecutive patients operated from 2010 to 2018 for CD were retrieved and 72 patients who had ileal, colonic or ileocolonic resection were selected and interviewed with the Cleveland Global Quality of Life (CGQL) questionnaire and the Body Image Questionnaire (BIQ). Disease activity was defined as the Harvey–Bradshaw Index (HBI). Comparisons between laparoscopic and open groups were carried out with non-parametric tests and log-rank test. Results Seventy-two patients who had laparoscopic ileal, colonic or ileocolonic resection and had a follow-up greater than 1 year were interviewed. The total CGQL score was associated with clinical disease activity at the moment of the interview (rho = −0.61, p < 0.0001) and to the presence of extraintestinal complication (rho = 0.28, p = 0.03). At multivariate analysis, disease activity at the moment of the interview and the presence of extraintestinal complication confirmed to be independent predictors of long-term quality of life. Conclusion Long-term quality of life after minimally invasive intestinal surgery is essentially predicted by current disease activity. Thus, it is crucial to prevent clinical CD recurrence
