Endoscopic Magnetic Compression Anastomosis For Small Bowel Bypass in a High Operative Risk Setting.

The endoscopic enteroenteral bypass could revolutionize the treatment of small bowel obstruction (SBO) in inoperable patients. We describe the technique of endoscopic delivery of a magnetic compression anastomosis device and the creation of an enteroenteral anastomosis in a patient with recurrent acute on chronic SBOs and prohibitively high operative risk. In this novel procedure, a magnetic compression anastomosis device is delivered on either side of the obstruction using a hybrid endoscopic/fluorographic technique, effectively bypassing the obstruction and relieving symptoms. The anastomosis was endoscopically evaluated at regular intervals postprocedure. By 7 days, healthy villi were visible through the mated magnetic rings. By 10 days, the anastomosis was widely patent. The rings passed through the ileostomy and were evacuated, and the patient's symptoms completely resolved. The anastomosis remained widely patent at 1 year. In summary, this case demonstrates the benefit of magnetic compression anastomosis in a patient with SBO and high operative risk.
