“…The successful treatment of LGEA in the infant may merit attention. MCA was previously reported for treating benign biliary strictures, [ 4 ] as magnetic connectors for coronary surgery, [ 5 ] and for the functional undiversion of ileostomyin pediatric patients. [ 6 ] At present, MCA for the treatment of EA patients is restricted to gross type A (without TEF) and anastomotic stenosis without thoracotomy.…”

Rationale: Neonatal long-gap esophageal atresia (LGEA) with tracheoesophageal fistula (TEF) is an uncommon but serious congenital malformation of the esophagus in newborns, and it remains challenging for pediatric surgeons. Magnetic compress has been shown to be effective for the treatment of LGEA in children and adults. However, the implementation of this unique technique for neonatal LGEA has not been evaluated. Patient concerns: A female infant was born at 37 weeks of gestation. Prenatal ultrasound imaging revealed signs of esophageal atresia, including the absence of the gastric bubble and polyhydramnios. Diagnoses: A diagnosis of LGEA with TEF was confirmed at birth by contrast X-ray. Interventions: She was treated with magnetic compression anastomosis (MCA) following an esophago-esophagostomy. Two magnetic rings were customized, and the MCA was conducted during the same stage surgery of ligating the TEF. Under the magnetic force, the 2 magnet rings pulled along the gastric tube to achieve anastomosis. The postoperative permanent suction of these 2 pouches was instituted, and spontaneous growth was awaited. Magnet removal was performed at 36 days, and enteral nutrition was continued via a gastric tube for 4 weeks at post-operation. Outcomes: The upper gastrointestinal contrast confirmed the anastomotic patency perfectly after 3 months. The patient was followed up for 18 months, and exhibited durable esophageal patency without dysphagia. Lessons: These results suggest that MCA is feasible and effective for treating LGEA in infants.

“…The MS employed in this study was based on magnetic anchoring, a highly popular technique [16][17][18][19][20][21][22]. These devices adsorb onto anchoring points through a magnetic field.…”

“…Thus, magnetic anchoring devices can act as a mechanical arm, grasping and retracting a tissue or organ, exposing the surgical field, and simplifying the operation. Along the same principle, Rivas et al [19] invented a magnetic gallbladder grasper. It consists of two main parts: an external magnet placed on the patient's right hypochondria, and a gallbladder grasper attached to the gallbladder.…”

Magnetic Spiderman, a New Surgical Training Device: Study of Safety and Educational Value in a Liver Transplantation Surgical Training Program

et al. 2019

Introduction Difficulties with liver transplantation (LT)‐related surgical techniques are great challenges for young surgeons. Thus, young surgeons need to undergo systematic preclinical training. However, an optimal training system for LT is still lacking. This study aims to evaluate the safety and educational value of the Magnetic Spiderman (MS) during LT‐related surgical techniques training, particularly during training for the preparation of the donor's liver and vascular reconstruction. Methods For the donor liver preparation training, the pulling force of the MS was measured using 16 porcine livers. Another 40 porcine livers were divided into two groups: MS group (used MS in the preparation of the liver) (n = 25) and manual group (took manual assistance in the preparation of the liver) (MA group, n = 15). In vascular reconstruction training, 25 pairs of porcine iliac veins were used to practice reconstruction. Five LT experts evaluated the MS for its use in LT‐related surgical techniques training. Results During the donor liver preparation training, the number of assistants required in the MS group was significantly less than the number required in the MA group (0 vs. 1.8 ± 0.1; P < 0.001). However, the number of vasculature leaking points was similar between the two groups (0.2 ± 0.1 vs. 0.4 ± 0.2; P = 0.51). In vascular reconstruction training, the trainee alone could complete the vascular reconstruction training, with a reconstruction success rate of 80% (20/25). All five experts considered the MS a viable alternative to assistants, with the ability to facilitate single surgeon training for LT. Four out of five (80%) experts considered MS quite safe for surgery and effective at keeping the surgical field clear. Conclusion MS can reduce the number of assistants to zero in LT‐related techniques training without increasing the risk of the operation, thus facilitating training for LT.

“…A similar use of an internal–external paired magnet system is also being studied in obstructive sleep apnea treatment—as an alternative to continuous positive airway pressure (CPAP)—by advancing the hyoid bone forward to maintain airway patency during sleep ( Figure 3 ) [ 102 , 133 ]. Other surgical applications of an internal–external paired magnetic system include the use of internal detachable magnetic graspers manipulated by external magnets to aid in organ retraction during laparoscopic gallbladder surgery and bariatric surgery to decrease the number of incisions ( Table 3 ) [ 91 , 92 , 93 , 95 , 96 , 134 ]. These multiple uses highlight the potential and versatility of magnetic surgical systems that can manipulate internal tissues via an external source.…”

The Evolving Use of Magnets in Surgery: Biomedical Considerations and a Review of Their Current Applications

2023

The novel use of magnetic force to optimize modern surgical techniques originated in the 1970s. Since then, magnets have been utilized as an adjunct or alternative to a wide array of existing surgical procedures, ranging from gastrointestinal to vascular surgery. As the use of magnets in surgery continues to grow, the body of knowledge on magnetic surgical devices from preclinical development to clinical implementation has expanded significantly; however, the current magnetic surgical devices can be organized based on their core function: serving as a guidance system, creating a new connection, recreating a physiologic function, or utilization of an internal–external paired magnet system. The purpose of this article is to discuss the biomedical considerations during magnetic device development and review the current surgical applications of magnetic devices.
