A review of the ifu revealed a list of precautions for the physician to review with the patient.Risks associated with failure to counsel the patient include, but are not limited to "early release of the flange, plug migration out of the fistula, fluid accumulation, infection, abscess, and failure of the fistula to heal." the ifu states that "if the flange is retained in the patient beyond an eight-week period, the patient should be monitored for bowel obstruction, erosion, perforation or flange migration." migration, fistula recurrence, and delayed or failed incorporation of the device are listed amongst the potential complications noted in the ifu.Lastly, the ifu notes that "the bowel fistula opening is the higher-pressure zone of the fistula, as well as the site of ingress of enteric contents into the fistula tract.The flange of the enterocutaneous fistula plug must therefore be flush against the bowel wall to restrict ingress of intestinal contents into the fistula." the root cause of the flange migration into the fistula tract is inconclusive.Factors that could contribute to this occurrence include, but are not limited to excess tension on the device, patient post-op care and activity, patient anatomy, size of the device in comparison to fistula size, and the integrity of the bowel opening.
