Afferent loop syndrome caused by malignant obstruction arises in a distinct oncologic context requiring a specific clinical approach. When obstruction results from cancer recurrence rather than a benign mechanical cause, endoscopic management is the method of choice.
This protocol covers afferent loop syndrome secondary to malignant obstruction. The obstruction may be caused by recurrence of malignancy at the anastomosis or in the surgical bed, locoregional lymphadenopathy, or peritoneal carcinomatosis. In all of these settings, endoscopic treatment is preferred.
Management centres on an endoscopic luminal approach to relieve the afferent loop stricture. Multiple stenting strategies have been described in the literature. The clinical goal is relief of the afferent loop obstruction. The complete structured regimen — including stent selection and procedural technique — is detailed in the full protocol.
