Reviving the poppy seed test for the diagnosis of colovesical fistula: A case report from a single rural center experience.

Key Clinical Message: The poppy seed test is a valuable, cost-effective, and sensitive initial diagnostic investigation to identify the presence of colovesical fistula, particularly for clinicians in remote or rural areas with lack of access to specialist radiologic, endoscopic, surgical, or urological support. The poppy seed test therefore may act as a bridge toward the commencement of appropriate referral pathways for the management of colovesical fistula.

Abstract: The diagnosis of colovesical fistula is resource intensive, often requiring a combination of radiological investigation and endoscopy.
