Positive Fecal Occult Blood Test After Prostate Cancer Surgery - Gastroenterology and Hepatology

More Info

---

Understanding a positive fecal occult blood test (FOBT) after prostate cancer surgery can be complex, especially considering your father's medical history. Let's break down the questions and concerns you have regarding the implications of a positive FOBT result, the potential influences of supplements like pomegranate extract, and the next steps in terms of further testing and specialist referrals.

1. Impact of Pomegranate Extract on FOBT Results: Pomegranate extract is often touted for its health benefits, particularly in relation to prostate health. However, there is limited research specifically addressing its effect on fecal occult blood tests. Generally, pomegranate is not known to cause false positives in FOBT. The test is designed to detect hemoglobin from blood in the stool, and while certain foods (like beets) can affect stool color, pomegranate is unlikely to interfere with the test results. Nonetheless, it is always wise to inform your healthcare provider about any supplements being taken, as they can provide tailored advice based on your father's overall health and treatment plan.

2. Influence of Hematuria (Blood in Urine) on FOBT Results: Blood in the urine (hematuria) and blood in the stool are separate issues, and one does not typically affect the other. However, the presence of hematuria may indicate underlying issues that could warrant further investigation. If your father is experiencing blood in his urine, it is essential to discuss this with his healthcare provider, as it may require additional diagnostic workup, such as imaging studies or cystoscopy, to rule out complications related to prostate cancer or other urinary tract issues.

3. Need for Colonoscopy: Given the positive FOBT result, a colonoscopy is often recommended to investigate the source of the bleeding. This is particularly important in the context of your father's prostate cancer history, as it is crucial to rule out any potential colorectal issues, including polyps or malignancies. The FOBT can indicate bleeding from various sources in the gastrointestinal tract, and a colonoscopy is the gold standard for direct visualization and biopsy if necessary.
4. Choosing the Right Specialist: In terms of which specialist to consult, both colorectal surgeons and gastroenterologists (hepatobiliary and gastrointestinal specialists) can perform colonoscopies. If the primary concern is the positive FOBT and potential colorectal issues, a gastroenterologist may be the most appropriate choice, as they specialize in gastrointestinal health and procedures. However, if there are specific concerns about surgical interventions or if your father has had previous colorectal issues, a colorectal surgeon might also be a suitable option. It may be beneficial to discuss this with your father's primary care physician or oncologist, who can provide a referral based on his specific medical needs.

In summary, a positive FOBT after prostate cancer surgery necessitates careful evaluation. While pomegranate extract is unlikely to affect the test results, the presence of hematuria and the positive FOBT warrant further investigation through a colonoscopy. Consulting a gastroenterologist would be a prudent next step to ensure comprehensive evaluation and management of your father's health concerns. Regular follow-ups and communication with his healthcare team are essential to navigate these complexities effectively.
