“…It is considered to be a safe surgical technique that is equivalent or superior to anastomoses created by traditional sutures or stapling techniques [ 10 ]. For certain diseases (bile duct anastomotic stricture or esophageal atresia) [ 17 – 20 ] or under extreme circumstances (inflammatory or infectious situation) [ 21 – 23 ], the MCA was as the safest way to construct anastomosis.…”

BackgroundAlthough commonly used procedure, Roux-en-Y hepaticojejunostomy (RYHJ) remains to be complicated, time consuming, and has a relatively poor prognosis. We designed the magnetic compressive anastomats (MCAs) to perform RYHJ more efficiently and safely.Materials and methods36 dogs were divided into two groups randomly. After obstructive jaundice model construction, RYHJ was performed with MCAs in study group or by hand-sewn in control group. Both groups were followed for 1, 3, and 6 months after RYHJ. The liver function and postoperative complications were recorded throughout the follow-up. At the end of each time point, dogs were sent for magnetic resonance imaging (MRI) and sacrificed. Anastomotic samples were taken for anastomotic narrowing rate calculation, histological analyses, tensile strength testing, and hydroxyproline content testing.ResultsThe anastomotic construction times were 44.20 ± 23.02 min in study group, compared of 60.53 ± 11.89 min in control group (p < 0.05). The liver function recovered gradually after RYHJ in both groups (p > 0.05). All anastomats were expelled out of the body in 8.81 ± 2.01 days. The gross incidence of morbidity and mortality was 33.3% (6/18) and 16.7% (3/18) in study group compared with 38.9% (7/18) and 22.2% (4/18) in control group (p > 0.05), and there is no single case of anastomotic-specific complications happened in study group. The narrowing rates of anastomosis were 14.6, 18.5, and 18.7% in study group compared with 35.4, 36.9, and 34% in control group at 1st, 3rd, and 6th month after RYHJ (p < 0.05). In study group, preciser alignment of tissue layers and milder inflammatory reaction contributed to the fast and better wound healing process.ConclusionPerform RYHJ with MCAs is safer, more efficient than by hand-sewn method in obstructive jaundice dog models.Electronic supplementary materialThe online version of this article (doi:10.1007/s00464-017-5740-5) contains supplementary material, which is available to authorized users.

“…[ 8 – 11 ] This observation introduced the idea that rectal atresia could be treated with an anastomosis formed by rare earth magnets (magnamosis). [ 4 ] Magnamosis has been successfully used in treatment of benign and malignant biliary strictures, magnetic connectors for coronary surgery, [ 12 , 13 ] and the functional magnamosis undiversion procedure of ileostomy in pediatric patients. [ 14 ] At present, MCA for the treatment of esophageal atresia patients is restricted to gross type A (without tracheoesophageal fistula [ 15 ] and anastomotic stenosis after definitive esophago-esophagostomy without thoracotomy.…”

“…After several communications with her parents, it was decided in agreement to attempt to approximate the 2 pouches by magnet force, as previously reported. [ 4 ] At age of 4 months, the patient underwent rectocecal anastomosis, and the distance has been confirmed less than 3 cm from blind end to anal edge in the rectum. A 12 mm magnet ring through the mucous fistula and a second magnet through the anus was implanted respectively to create a magnamosis between the distal and proximal pouches (Fig.…”

Rationale: Rectal atresia caused by necrotizing enterocolitis (NEC) is a serious and rare complication in children. Magnetic compression anastomosis (MCA) has been effectively applied in children with congenital oesophageal atresia and biliary atresia. Herein, we reported a case of successfully application of MCA in an infant with rectal atresia following NEC. Patient concerns: A 30 +6 weeks premature birth female fetal infant was transferred to our neonatal intensive care unit due to premature delivery, low birth weight, and neonatal respiratory distress. On postpartum day 11, the infant developed abdominal distension and mucosanguineous feces. This infant was then clinically diagnosed as NEC. She underwent anesthesia and intestinal fistula operation on postpartum day 11 because of NEC. Diagnosis: After 3 months, radiographic examination revealed rectal atresia and stricture. Interventions: This infant was successfully treated with MCA following a cecum-rectal anastomosis and ileocecal valve was reserved. Outcomes: On postoperative day 9, she passed the 2 magnets per rectum. In addition, there were no difficult defecation or fecal incontinence or other short-term complications. After the 7-month follow-up, the patient had an excellent clinical outcome. Lessons: MCA is a feasible and effective method for treating rectal atresia in infants.

Magnamosis: a novel technique for the management of rectal atresia

Abstract: We report a case of rectal atresia treated using magnets to create a rectal anastomosis. This minimally invasive technique is straightforward and effective for the treatment of rectal atresia in children.
