Afferent loop syndrome may develop when a benign stricture forms at the gastrojejunal anastomotic site of the afferent limb, obstructing normal drainage and producing the clinical features of afferent loop obstruction.
In this scenario, a benign anastomotic stricture is present at the afferent limb gastrojejunal anastomotic site. Benign enteral strictures can arise from fibrosis at this anastomotic site. When such a stricture underlies the syndrome, a targeted approach to the structural lesion itself is indicated.
The protocol specifies an endoscopic intervention directed at the anastomotic stricture — the full procedural details and criteria are contained in the structured regimen.
Obliteration of the anastomotic stricture with relief of afferent loop obstruction.

One exception is anastomotic ulcerations and associated strictures which may be managed endoscopically with balloon dilations.
Benign enteral strictures may occur as a result of radiation enteropathy or fibrosis at the afferent limb GJ anastomotic site.
Alves et al. described the successful use of endoscopic balloon dilation to obliterate an anastomotic stricture in a patient with a previous gastrectomy with Roux-en-Y reconstruction.
