“…In the field of adult surgery, magnets have also been used for a wide spectrum of applications, including duodeno–ileal anastomosis [ 33 , 34 ], ureterostenosis after kidney transplantation [ 35 ], hepaticojejunostomy [ 36 , 37 ], biliary strictures [ 38 , 39 , 40 ], as well as for foregut issues, such as strictures after esophageal cancer surgery [ 41 ] and sleeve gastrectomy [ 42 ].…”

Originating in the 1970s, magnetic compression anastomosis (MCA) has lately been revisited with a focus on minimal invasive surgery (MIS). The aim of this report is to reappraise our earlier experience with MCA with the intention of facilitating future MCA advancement. A retrospective review was conducted regarding preclinical experiments and clinical trials at a single institution from 1980 to 1995. The reviewed information was compiled and appraised to generate proposals for future MCA use. The experimental studies, including 250 MCA cases in gastrointestinal and urinary tract animal models, demonstrated the technical versatility of MCA as well as the superior biomechanical characteristics in comparison to hand-sewn anastomoses. Clinical trials encompassed 87 MCA procedures in 86 children, 2 to 10 years of age, involving the following techniques: non-operative esophageal recanalization (n = 15), non-operative ileostomy undiversion (n = 46), Swenson pull-through (n = 10), non-operative urethral recanalization (n = 5), and extravesical ureterocystoneostomy (n = 11). Clinical MCA was found to be successful in over 87% of cases. MCA limitations concerning anastomotic failure and scarring were thought to be mostly due to inadequate magnetic compression. Based on our historic experience, we propose further research on the technical aspects of MCA, along with the biological aspects of anastomotic tissue remodeling. Magnets should be designed and manufactured for a wide spectrum of pediatric surgical indications, particularly in combination with novel MIS techniques.

Background: The problems associated with shaft-based instrumentation include restricted manoeuvrability, restricted visibility and sword fighting of instruments. One of the easiest solutions is to reduce the number of working ports. A unique approach is by the use of a natural force of nature i.e.; magnetism. In this study, we have tried to incorporate the properties of magnetism and magnetic substances to the advantage of surgeons and hence, patients.Methods: The magnet employed in our study is a 3500 Gauss magnet, of 15×10 cm which was placed over the anterior abdominal wall in a sterile manner. The magnet was moved along the anterior abdominal wall in order to manipulate and mobilize intra-abdominal tissue. Laparoscopic bull dog clamps as well as B. P. handles were used intra-peritoneally to grasp tissue, which in turn are mobilised by the magnet. The end point evaluated was of safety and feasibility to adequately mobilize and manipulate organs to achieve effective exposure for dissection.Results: In total, we have successfully completed 15 surgical procedures using magnet assisted tool. Eight patients underwent magnet assisted laparoscopic appendectomy. three patients underwent magnet assisted laparoscopic cholecystectomy. Four patients underwent magnet assisted mesh repair for ventral hernias. None of the patients developed magnet related complications.Conclusions: Magnet assisted laparoscopic surgery is feasible and easy to use. The cost can be minimal. This is a new concept that is here to stay and will become integrated into many other forms in the future. In the rapidly evolving world of surgery, with invasiveness of surgery on the downward trend, magnetism may be the answer to the next leap in surgery: non-invasive surgery.
