“…In fact, its use in thoracic surgery has also been described. Chen et al described the use of the magnetic anchoring and traction system (MATS) to facilitate esophageal dissection in a porcine model [31] . This system is composed of an external unit of Nd 2 Fe 14 B covered with nickel and an internal stainless steel cylinder.…”

“…Although this inconvenience was first noted during the animal trials, other groups have accounted for it when used in patients with higher BMI as they tend to have thicker abdominal walls [25] . Interestingly, in the studies of MATS, the attraction force measured (in Newtons) was compared to the distance between the magnets in millimeters [31,32] . In the study graphs, it can be seen that with a distance of 80 mm, the force of the magnets is minimal, which can account for the loss of coupling seen in patients with thicker abdominal walls.…”

The incorporation of magnetic fields into surgery to reduce the invasiveness of minimally invasive surgery led to the creation of magnetic-assisted surgery. External magnets coupled with their internal counterparts assist during surgical procedures, avoiding the need for additional trocars. Multiple advances have been made in this field in the past 15 years, with new promising technologies being developed. This review centers on the history of magnetic-assisted surgery and the available evidence of its safety, benefits and discusses the very promising combination of this new paradigm-shift technology with robotics.

“…This challenge is compounded by the elevated morbidity rates linked to lymphadenectomy in this region, potentially exerting an adverse impact on both prognosis and the quality of life (QoL) 4 . Therefore, many different methods, such as ʻbascule methodʼ 5 , ʻstripping methodʼ 6 , and ʻmagnetic anchoring methodʼ 7 , were reported with the intention of reducing the risk of iatrogenic LRLN injury. Nonetheless, each of method has its pros and cons, and a consistent surgical strategy has not yet been established.…”

Background: Lymph nodes along the left recurrent laryngeal nerve (LRLN) is thought to be highly involved in esophageal cancer. Given the unique anatomical positioning of the nerve, performing lymphadenectomy in this region requires advanced techniques within limited working space. Meanwhile, high incidence of morbidity and mortality is associated with lymphadenectomy. Although several methods have been applied to reduce the technical requirement and the incidence of postoperative complication, the optimal method remains controversial. Methods: This study was a single-center, prospective, randomized trial to investigate the utility of lymphadenectomy along the LRLN during the minimally invasive esophagectomy (MIE) in esophageal squamous cell carcinoma (ESCC) patients by comparing the surgical outcome, postoperative complication, survival rate and quality of life (QoL) between the retraction method (RM) and the suspension method (SM) in patients with esophageal cancer from June 2018 to November 2020. QoL was assessed according to questionnaire: EQ-5D-5L. Results: Of 94 patients were enrolled and randomized allocated to RM and SM group equally. Characteristics did not differ between groups. The duration of lymph node dissection along LRLN was significant longer in SM group (P<0.001). No difference was observed about postoperative complications. One of in-hospital death was occurred in each group (P>0.999). Patients in neither of groups exhibiting difference about 3-year disease free survival rate (P=0.180) and overall survival rate (P=0.430). No difference was observed in postoperative QoL between groups at different time points (all, P>0.05). Conclusion: Both methods of lymph node dissection along the LRLN during MIE in ESCC patients are technically feasible and safe. The RM appears more favorable in terms of reducing surgical duration compared to the SM.
