Endoscopic recanalization of a completely obstructed colorectal anastomosis using magnets

A male patient who had undergone emergency loop colostomy because of intestinal obstruction secondary to a sigmoid colon tumor subsequently underwent elective rectosigmoidectomy. Endoscopy prior to bowel reconstruction revealed complete stenosis of the colorectal anastomosis ([Fig. 1]). A previous attempt at recanalization using a needle-knife was aborted due to perforation. Following a multidisciplinary discussion, the decision was made to perform magnetic compression anastomosis.
