Reviving the poppy seed test for the diagnosis of colovesical fistula: A case report from a single rural center experience.
Article in Clinical case reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
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. The poppy seed test is a non-invasive and cost-effective alternative that has been demonstrated to identify presence of colovesical fistula with high sensitivity. There is however a noticeable paucity of recommendations for the poppy seed test in the diagnostic approach to colovesical fistula due to significant advancements in alternative radiologic and endoscopic technologies. Despite this, in resource-challenged areas with lack of specialist support, the poppy seed test is a cost-effective, accessible and safe test that can be performed to confirm the presence of colovesical fistula. We report a case of a 79-year-old man with a past history of colorectal cancer managed surgically with adjuvant chemoradiotherapy who develops noisy micturition, pneumaturia, and fecaluria 22 years after treatment. Given the suspicion of colovesical fistula, computed tomography imaging and cystoscopy were performed which was unable to demonstrate an overt fistula. The poppy seed test was utilized and demonstrated presence of poppy seeds in the urine, confirming the presence of a fistula. The patient was referred to a specialist surgical center for consideration of further management. The poppy seed test is a valuable initial diagnostic investigation for clinicians in remote or rural areas with lack of access to specialist radiologic, endoscopic, surgical, or urological support in confirming the presence of a colovesical fistula and initiating referral pathways for the management of this condition.
