Abstract
Magnetic compression anastomosis is a promising treatment option for patients with complex esophageal atresia; but, at the present time, should not be the first therapeutic option in those cases where the surgeon can perform a primary anastomosis of the two ends of the esophagus with acceptable tension.

Lessons Learned From the First-In-Human Compassionate Use of Connect-EA™ in Ten Patients With Esophageal Atresia. J Pediatr Surg 2024; 59:437-444. [PMID: 37838619 DOI: 10.1016/j.jpedsurg.2023.09.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 09/12/2023] [Accepted: 09/15/2023] [Indexed: 10/16/2023]
Abstract
INTRODUCTION Delayed primary repair of esophageal atresia in patients with high-risk physiologic and anatomic comorbidities remains a daunting challenge with an increased risk for peri-operative morbidity and mortality via conventional repair. The Connect-EA device facilitates the endoscopic creation of a secure esophageal anastomosis. This follow-up study reports our long-term outcomes with the novel esophageal magnetic compression anastomosis (EMCA) Connect-EA device for EA repair, as well as lessons learned from the ten first-in-human cases. We propose an algorithm to maximize the advantages of the device for EA repair. METHODS Under compassionate use approval, from June 2019 to December 2022, ten patients with prohibitive surgical or medical risk factors underwent attempted EMCA with this device. All patients underwent prior gastrostomy, tracheoesophageal fistula ligation (if necessary), and demonstrated pouch apposition prior to EMCA. RESULTS Successful device deployment and EMCA formation were achieved in nine patients (90%). Mean time to anastomosis formation was 8 days (range 5-14) and the device was retrieved endoscopically in five (56%) cases. At median follow-up of 22 months (range 4-45), seven patients (78%) are tolerating oral nutrition. Balloon dilations (median 4, range 1-11) were performed either prophylactically for radiographic asymptomatic anastomotic narrowing (n = 7, 78%) or to treat clinically-significant anastomotic narrowing (n = 2, 22%) with no ongoing dilations at 3-month follow up post-repair. CONCLUSION EMCA with the Connect-EA device is a safe and feasible minimally-invasive alterative for EA repair in high-risk surgical patients. Promising post-operative outcomes warrant further Phase I investigation. LEVEL OF EVIDENCE IV, Case series of novel operative technique without comparison group.

Abstract
Since the 1970s, magnets have been progressively harnessed for use in minimally invasive treatment of pediatric surgical disease. In particular, multiple magnetic devices have been developed for treating esophageal atresia, pectus excavatum and scoliosis. These devices, which can be placed via small incisions or under endoscopic or fluoroscopic guidance, provide the added benefit of sparing patients multiple large, invasive procedures, and allowing for gradual correction of congenital anomalies over days to months, depending on the disease. In the following text, we detail the current landscape of magnetic devices used by pediatric surgeons, illustrate their use through clinical cases, and review the available body of literature with respect their outcomes and complications.

Abstract
BACKGROUND Esophageal atresia (EA) is a life-threatening congenital malformation in newborns, and the traditional repair approaches pose technical challenges and are extremely invasive. Therefore, surgeons have been actively investigating new minimally invasive techniques to address this issue. Magnetic compression anastomosis has been reported in several studies for its potential in repairing EA. In this paper, the primary repair of EA with magnetic compression anastomosis under thoracoscopy was reported.
CASE SUMMARY A full-term male weighing 3500 g was diagnosed with EA Gross type C. The magnetic devices used in this procedure consisted of two magnetic rings and several catheters. Tracheoesophageal fistula ligation and two purse strings were performed. The magnetic compression anastomosis was then completed thoracoscopically. After the primary repair, no additional operation was conducted. A patent anastomosis was observed on the 15th day postoperatively, and the magnets were removed on the 23rd day. No leakage existed when the transoral feeding started.
CONCLUSION Thoracoscopic magnetic compression anastomosis may be a promising minimally invasive approach for repairing EA.

Abstract
Background: Magnetic compression anastomosis (MCA) is an alternative technique for patients with long-gap esophageal atresia (EA). It allows for preservation of the native esophagus. We aimed to systematically summarize the current literature on MCA in EA. Methods: Studies where neonates with EA were treated with MCA devices were included, while studies on esophageal stenosis were excluded. All clinical studies, including comparative studies, case series, and case reports, were eligible for inclusion. Methodological quality assessment was performed using a validated tool. Results: Twelve studies with a total of 42 patients were included in this review. There was a wide variation among these studies with regard to the time of initiation of MCA (1 day to 7 months), procedure time (13-320 minutes), and magnet characteristics (strength, size, and shape of the magnets used). The time to achieve anastomosis ranged from 1 to 12 days. Stricture at the anastomotic site was reported in almost all the patients, which required multiple endoscopic dilatations (median no. of dilatations/patient = 9.8). Stent placement for refractory stricture was required in 9 (21%) patients, and surgery for stricture was required in 6 (14%) patients. Long-term outcomes included esophageal dysmotility (n = 3) and recurrent pulmonary infections (n = 3) were reported in only four studies. Conclusion: As per the findings of this review, neonates with long-gap EA undergoing MCA would invariably require multiple sittings of endoscopic dilatations (median no. of dilatations/patient = 9.8). Also, there is a wide variation among the included studies in terms of the procedure of MCA. Future studies with a standardized procedure for achieving MCA are needed to determine additional outcomes in this fragile patient population.

Abstract
Since the 1970s, magnetic force has been used to augment modern surgical techniques with the aims of minimizing surgical trauma and optimizing minimally-invasive systems. The majority of current clinical applications for magnetic surgery are largely centered around gastrointestinal uses-such as gastrointestinal or bilioenteric anastomosis creation, stricturoplasty, sphincter augmentation, and the guidance of nasoenteric feeding tubes. However, as the field of magnetic surgery continues to advance, the development and clinical implementation of magnetic devices has expanded to treat a variety of non-gastrointestinal disorders including musculoskeletal (pectus excavatum, scoliosis), respiratory (obstructive sleep apnea), cardiovascular (coronary artery stenosis, end-stage renal disease), and genitourinary (stricture, nephrolithiasis) conditions. The purpose of this review is to discuss the current state of innovative magnetic surgical devices under clinical investigation or commercially available for the treatment of non-gastrointestinal disorders.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND Aim of study is to report our preliminary experience with magnetic anastomosis (magnamosis) treating long-gap esophageal atresia (LGEA), the most challenging condition of esophageal atresia continuum. Magnamosis has been reported in 20 patients worldwide as an innovative and marginally invasive option. METHODS Prospective evaluation of all LGEA patients treated with magnamosis was performed (study registration number: 2535/2021). Main outcomes considered were demographic and surgical features, postoperative complications and feeding within 6-month of follow-up. RESULTS Between June 2020 and January 2021, 5 LGEA patients (Type A, Gross classification) were treated. Median preoperative gap was 5 vertebral bodies. Magnetic bullets were placed at an average age of 81 days of life, leading to successful magnamosis in all cases: 4 infants had primary magnetic repair (one after thoracoscopic mobilization of the pouches), 1 patient had a delayed magnamosis after Foker's procedure. Esophageal anastomosis was achieved after an average of 8 days. No anastomotic leak was found. All patients developed anastomotic stenosis at 6-month follow-up, requiring a mean of 6 dilations each. Full oral feeding was achieved in 3 patients, while 2 were still on oral-gastrostomy feeding. One patient experienced small esophageal perforation after dilation (3 months after magnamosis), distal to the anastomotic stricture and subsequently developed oral aversion. CONCLUSIONS Our preliminary results suggest magnamosis a safe and effective minimally invasive option in patients with LGEA. Absence of postoperative esophageal leaks may represent a major advantage of magnamosis over conventional surgery, although possible high rate of esophageal stenosis should be further evaluated.

Abstract
INTRODUCTION Preservation of native esophagus is a tenet of esophageal atresia (EA) repair. However, techniques for delayed primary anastomosis are severely limited for surgically and medically complex patients at high-risk for operative repair. We report our initial experience with the novel application of the Connect-EA, an esophageal magnetic compression anastomosis device, for salvage of primary repair in 2 high-risk complex EA patients. Compassionate use was approved by the FDA and treating institutions. OPERATIVE TECHNIQUE Two approaches using the Connect-EA are described - a totally endoscopic approach and a novel hybrid operative approach. To our knowledge, this is the first successful use of a hybrid operative approach with an esophageal magnetic compression device. OUTCOMES Salvage of delayed primary anastomosis was successful in both patients. The totally endoscopic approach significantly reduced operative time and avoided repeat high-risk operation. The hybrid operative approach salvaged delayed primary anastomosis and avoided cervical esophagostomy. CONCLUSION The Connect-EA is a novel intervention to achieve delayed primary esophageal repair in complex EA patients with high-risk tissue characteristics and multi-system comorbidities that limit operative repair. We propose a clinical algorithm for use of the totally endoscopic approach and hybrid operative approach for use of the Connect-EA in high-risk complex EA patients.

Hornok Z, Kubiak R, Csukas D, Ferencz A, Cserni T. Esophageal Magnetic Anastomosis Device (EMAD) to simplify and improve outcome of thoracoscopic repair for esophageal atresia with tracheoesophageal fistula: A proof of concept study. J Pediatr Surg 2022:S0022-3468(22)00631-5. [PMID: 36307298 DOI: 10.1016/j.jpedsurg.2022.09.040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Revised: 09/04/2022] [Accepted: 09/22/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND We designed a new Esophageal Magnetic Anastomosis Device (EMAD) for thoracoscopic repair of esophageal atresia (EA) with tracheoesophageal fistula (TEF) without the need of handheld suturing or additional gastrostomy. METHODS Synthetic EA-TEF model: Spherical and tubular shaped rubber balloons and a term infant sized plastic doll were used. Medical students (n = 10) and surgical trainees (n = 10) were asked to perform thoracoscopic repair of an "EA" with a hand sutured anastomosis (HA) and with the EMAD. Euthanized animal model: The esophagus in 5 piglets (3-4 kg) was dissected and a thoracoscopic esophageal magnetic anastomosis (EMA) was performed. Bursting pressure (BP) and pulling force (PF): HA and EMA were created on ex vivo New Zealand white rabbit (2.5-3 kg) esophagi (n = 25 in each test series). BP and PF were measured and compared against each other. RESULTS Medical students were unable to complete HA, but were successful with the EMAD in 11.1 ± 2.78 min. Surgical trainees completed EMA in 4.6 ± 2.06 min vs. HA 30.8 ± 4.29 min (p<0.001). The BP following a HA (14.1 ± 3.32 cmH2O) was close to the physiological intraluminal pressure reported in a neonatal esophagus (around 20 cmH2O), whereas the BP with the EMAD was extremely high (>90 cmH2O) (p<0.001). The PF of an EMA (1.8 ± 0.30 N) was closer to the safety limits of anastomotic tension reported in the literature (i.e. 0.75 N) compared with the HA (3.6 ± 0.43 N) (p<0.0001). CONCLUSION The EMAD could simplify, shorten, and potentially improve the outcome of thoracoscopic repair for EA with TEF in the future. A high BS and a relative low PF following EMAD application may lower the risk of postoperative complications such as esophageal leakage and stricture formation.

Abstract
BACKGROUND Magnetic compression anastomosis (MCA) is a novel suture-free reconstruction of the digestive tract. It has been used in gastrointestinal anastomosis, jejunal anastomosis, cholangioenteric anastomosis and so on. The traditional operative outcomes of congenital esophageal atresia and benign esophageal stricture are poor, and there are too many complications postoperatively. AIM To test MCA technology to reconstruct the esophagus in dogs, prior to studying the feasibility and safety of MCA in humans. METHODS Thirty-six dogs were randomized into either the study or control group (n = 18 per group). The dogs in the study group were subjected to end-to-end esophageal anastomosis with the magnetic compression device, while those in the control group underwent hand-sewn anastomosis with 4-0 absorbable multifilament Vicryl. We used interrupted single-layer inverting sutures. The anastomosis time, gross appearance, weight and pathology of the anastomosis were evaluated at one month, three months and six months postoperatively. RESULTS The anastomosis time of the MCA group was shorter than that of the hand-sewn group (7.5 ± 1.0 min vs 12.5 ± 1.8 min, P < 0.01). In the MCA group, X-ray examination was performed every day to locate the magnetic device in the esophagus before the magnetic device fell off from the esophagus. In the hand-sewn group, dogs did not undergo X-ray examination. One month after the surgeries, the mean weight of the dogs in the hand-sewn group had decreased more than that of the dogs in the MCA group (11.63 ± 0.71 kg vs 12.73 ± 0.80 kg, P < 0.05). At 3 mo and 6 mo after the operation, the dogs' weights were similar between the two groups (13.75 ± 0.84 kg vs 14.03 ± 0.82 kg, 14.93 ± 0.80 kg vs 15.44 ± 0.47 kg). The number of inflammatory cells in MCA group was lower than that in hand-sewn group on 1 mo after operation. CONCLUSION MCA is an effective and safe method for esophageal reconstruction. The anastomosis time of the MCA group was less than that of the hand-sewn group. This study shows that MCA technology may be applied to human esophageal reconstruction, provided these favorable results are confirmed by more publications.

Abstract
In the pediatric surgical environment, we can enrich our knowledge and improve our skills through interdisciplinary knowledge transfer in exchange with other surgical or even non-surgical disciplines. To demonstrate this, we present in this article three patient cases of method transfer enabling new techniques in minimally invasive pediatric surgery. 1. The somewhat modified application of the AeroStat rigid tip laparoscopic cholangiography catheter during the single-step laparoscopic cholecystectomy facilitates the safe intraoperative cholangiography with common bile duct flushing. 2. A magnetic rod is used during laparoscopic enterotomy to locate and retrieve ingested magnets. 3. Using a patient-specific MRI 3D model representing a syndromic high anorectal malformation improves surgical planning and parental education.

Esophageal Magnetic Compression Anastomosis in Esophageal Atresia Repair: A PRISMA-Compliant Systematic Review and Comparison with a Novel Approach. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9081113. [PMID: 35892616 PMCID: PMC9394416 DOI: 10.3390/children9081113] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 07/12/2022] [Accepted: 07/22/2022] [Indexed: 12/29/2022]
Abstract
The use of magnet compression to endoscopically create an esophageal anastomosis is an intriguing approach to esophageal atresia repair, but published cases with an existing available device have demonstrated mixed success. One major shortcoming has been the formation of subsequent severe, recalcitrant strictures after primary repair. To address the limitations of the existing device, we recently introduced and reported success with specially designed bi-radial magnets that exhibit a novel geometry and unique tissue compression profile. The aim of this study is to compare the outcomes using our novel device (novel group, NG) with those of previous reports which utilized the historical device (historic group, HG) in a PRISMA-compliant systematic review. Seven studies were eligible for further analysis. Additionally, one of our previously unreported cases was included in the analysis. Esophageal pouch approximation prior to primary repair was performed more frequently in the NG than in the HG (100% NG vs. 21% HG; p = 0.003). There was no difference in the overall postoperative appearance of postoperative stricture (95% HG vs. 100% NG; p = 0.64). The number of postoperative dilatations trended lower in the NG (mean 4.25 NG vs. 9.5 HG; p = 0.051). In summary, magnetic compression anastomosis adds a new promising treatment option for patients with complex esophageal atresia. Prior approximation of pouches and a novel magnet design have the potential to lower the rate of stricture formation.
