ABSTRACT
Objective To investigate the clinical efficacy of magnetic compression anastomosis for congenital esophageal atresia and stenosis.Methods The retrospective and descriptive study was conducted.The clinical data of 4 children who underwent magnetic compression anastomosis for congenital esophageal atresia and stenosis in the Northwest Women and Children's Hospital from December 2017 and February 2019 were collected.There were 2 males and 2 females.The children were aged 11 days,7 days,5 days,and 3 years,respectively.The children underwent magnetic compression anastomosis.Observation indicators:(1) surgical and postoperative situations;(2) follow-up.Follow-up using outpatient examination and telephone interview was performed to detect food intake and complications of children up to May 2019.Measurement data with normal distribution were represented as Mean±SD,and measurement data with skewed distribution were represented as M (range).Results (1) Surgical and postoperative situations:four children underwent magnetic compression anastomosis successfully.Of the 4 children,3 with esophageal atresia underwent open tracheoesophageal fistula repair and endoscopeassisted magnetic compression anastomosis,and 1 with congenital esophageal stenosis underwent endoscopic gastrostomy combined with magnetic compression anastomosis.The operation time of 4 children was (2.3±0.9) hours.The length of esophageal blind ending in the 3 children with esophageal atresia and length of esophageal stenosis were in the children with esophageal stenosis 30-35 mm and 8 mm.Four children has good magnet apposition,and time of postoperative magnet removal was (29± 10)days.Three children with esophageal atresia had oral removal of magnet,and 1 with esophageal stenosis had magnet removed by gastrostomy.One child complicated with postoperative fistula and anastomotic stenosis was cured by unobstructed drainage and nutritional support treatment.The duration of postoperative hospital stay was (39± 10)days.(2) Follow-up:4 patients were followed up for 3-17 months,with a median time of 10 months,and restored to oral intake after oral removal of magnet and removal of magnet by gastrostomy on the days 14-36 postoperatively.One child was detected anastomotic stenosis by esophagography at the postoperative 3 months,and was improved after esophageal dilatation.The other 3 children recovered to normal connectivity of esophagus postoperatively and maintain unobstructed.Four children had normal eating,without dysphagia or other serious complications.Conclusion Magnetic compression anastomosis is safe and feasible for congenital esophageal atresia and stenosis,with good short-term efficacy.
ABSTRACT
A new system of blood flow block for control of bleeding in abdominal operation is composed of an abdominal magnetic blocking unit, an abdominal external electromagnet unit and other non-magnetic operation instrument. The abdominal external electromagnetic unit is placed in advance in the operation bed. The abdominal magnetic blocking unit can be placed directly on the ventral of the large vessels when need to blocking the abdominal large vessels during the operation. According to the non-contact suction characteristics of magnetic materials, the two magnetic units will attract each other and compression the vessels. Using this system for vascular occlusion does not need clear exposure and without separating vessel. There is the advantage of rapid, accurate and reliable for the system.
