Can a patient with Crohn's disease undergo a transrectal prosthetic biopsy?

Transrectal Prostatic Biopsy in Patients with Crohn's Disease

Patients with Crohn's disease should not undergo transrectal prostatic biopsy due to the high risk of infectious complications and poor wound healing associated with perianal Crohn's disease. 1

Risks and Considerations

• Patients with Crohn's disease have a higher risk of developing perianal complications, including abscesses and fistulas, which can be exacerbated by invasive transrectal procedures 1
• Crohn's disease is characterized by transmural inflammation that can affect any part of the gastrointestinal tract, including the perianal region, increasing the risk of procedure-related complications 2
• The perianal region in Crohn's disease patients often has compromised tissue integrity and impaired healing capacity, making it susceptible to infection and delayed healing after invasive procedures 1
• Perianal sepsis is a common manifestation of Crohn's disease that requires careful management, and any invasive procedure in this area could trigger or worsen existing disease 1

Alternative Approaches

• For patients requiring prostatic tissue sampling, alternative approaches should be considered, such as:
  • Transperineal prostatic biopsy, which avoids the rectal mucosa and reduces the risk of fecal contamination 1
  • MRI-guided biopsy approaches that may offer safer alternatives for patients with perianal Crohn's disease 1
• Any procedure involving the perianal region in Crohn's disease patients should be performed only after:
  • Comprehensive assessment of disease activity including pelvic MRI scan 1
  • Endoscopic assessment of rectal mucosa to evaluate for active inflammation 1
  • Consultation with a multidisciplinary team including gastroenterology and colorectal surgery 1

Management Principles if Procedure is Absolutely Necessary

• If a transrectal prostatic biopsy is deemed absolutely necessary despite the risks:
  • The procedure should only be performed when Crohn's disease is in complete remission with no active rectal or perianal inflammation 1
  • Prophylactic antibiotics should be administered, with broader coverage than typically used for standard transrectal biopsies 1
  • The patient should be closely monitored post-procedure for signs of infection or abscess formation 1
  • Any post-procedure abscess must be promptly and adequately drained surgically 1

Recommendations for Clinical Practice

• Patients with Crohn's disease requiring prostatic evaluation should be managed under joint care of a urologist, gastroenterologist, and colorectal surgeon with experience in inflammatory bowel disease 1
• The decision-making process should prioritize the patient's overall disease status, with careful consideration of the risks of triggering perianal disease flares 1
• For patients with active perianal Crohn's disease, any elective prostatic biopsy should be deferred until the disease is well-controlled 1
• Medical optimization of Crohn's disease should be achieved before considering any invasive perianal procedure 1

Important Caveats

• Even in patients with seemingly inactive Crohn's disease, subclinical inflammation may be present, increasing the risk of complications from transrectal procedures 3
• The disconnect between symptoms and inflammation in Crohn's disease means that patients may have significant rectal inflammation even without obvious symptoms 3
• Surgical interventions in Crohn's disease should generally be limited to symptomatic disease rather than asymptomatic findings 1
• Poor wound healing is a well-documented complication of perianal procedures in Crohn's disease patients, even for seemingly minor interventions 1
