RESUMO

AIM: The medico-surgical strategy for the treatment of perianal fistulizing Crohn's disease (CD) following surgical drainage remains challenging and debated. Our aims were to describe the failure rate of therapeutic interventions after drainage of the fistula tract and determine the factors associated with failure to optimize medico-surgical strategies. METHOD: All consecutive patients with perianal fistulizing CD who underwent surgical drainage with at least a 12-week follow-up were included. Failure was defined as the occurrence of at least one of the following items: abscess recurrence, purulent discharge from the tract, visible external opening and further drainage procedure(s). RESULTS: One hundred and sixty-nine patients were included. The median follow-up was 4.0 years. The cumulative failure rates were 20%, 30% and 36% at 1, 3 and 5 years, respectively. The cumulative failure rates in patients who had sphincter-sparing surgeries or seton removal were significantly higher than in those who had a fistulotomy. Anterior fistula [hazard ratio (HR) = 2.52 (1.13-5.61), P = 0.024], supralevator extension [HR = 20.78 (3.38-127.80), P = 0.001] and the absence or discontinuation of immunosuppressants after anal drainage [HR = 3.74 (1.11-12.5), P = 0.032] were significantly associated with failure in the multivariate analysis model. CONCLUSION: Combined strategies for perianal fistulizing CD lead to a failure rate of 36% at 5 years. Where advisable, fistulotomy may be preferred because it has a lower rate of recurrence. The benefits of immunosuppressants require a dedicated prospective randomized trial.

RESUMO

AIM: To compare the rate of failure of radiofrequency thermocoagulation for anal fistula with that of rectal advancement flap in a case-matched study. METHOD: Patients who underwent radiofrequency treatment were compared with age- and sex-matched patients with Crohn's disease (CD) who underwent a rectal flap procedure. Fistula features, general characteristics and the main clinical events were recorded in a prospective database. Failure was defined by at least one of following: abscess, purulent discharge, visible external opening or further drainage procedure. RESULTS: A total of 62 patients [median age 45 (range 36.8-57.5) years; 22 women, 40 men; 22 with CD] were analysed. The failure rate of radiofrequency treatment was higher than that of rectal flap treatment (74.2% vs 32.2%; P = 0.004). The cumulative probabilities of failure of the radiofrequency treatment were 53.8% (38.8-68.3), 71.8% (55.3-84.0) and 87.4% (70.6-95.3) at 3, 6 and 12 months, respectively. Three patients in the radiofrequency group required drainage for an abscess and one had severe thermal ulceration. The Cox proportional hazards regression model (surgical procedure, obesity, CD) showed rectal flap treatment [3.48 (1.60-8.07); P = 0.001] and CD [2.60 (1.16-6.41); P = 0.02] to be the main independent predictors of healing. CONCLUSION: Radiofrequency thermocoagulation is a less satisfactory sphincter-sparing treatment for the management of anal fistula than a rectal flap procedure.

RESUMO

AIM: Rectal flap advancement is still a part of therapeutic management of anal fistulas. Data on the outcome of rectal flap advancement in patients with Crohn's disease (CD) is scarce. Our objective was to ascertain rates of failure of rectal flap advancement and to determine predictive factors for failure, with a special focus on CD METHOD: The patients' details, the characteristics of the fistula and the main clinical and therapeutic events were prospectively assessed among patients who underwent rectal flap advancement. All patients had a partial-thickness rectal flap advancement. Failure of primary rectal flap advancement was defined as the occurrence of at least one of the following: abscess, discharge, visible external opening, further drainage procedure. The rates of failure of rectal flap and the predictive factors of failure were assessed. RESULTS: Eighty-seven patients (34 patients with CD) were included. The median (interquartile range) follow-up was 13.3 (3.8-38.1) months. The cumulative failure rates were 15.9% (10.3-23.6), 23.0% (16.0-31.8), 31.6% (22.9-41.8) and 41.3% (30.5-53.0) at 3, 6, 12 and 24 months respectively. These data were comparable in Crohn's patients. Those with a supralevator fistula [hazard ratio 2.53 (1.01-7.71), P = 0.0476] and patients who had fewer than two fistula drainages before rectal flap [hazard ratio 3.19 (1.40-8.23), P = 0.005] were associated with higher rectal flap failure rates. In CD patients, the absence of biological therapy at referral was predictive of failure. CONCLUSION: Rectal flap advancement is a satisfactory option for the therapeutic management of anal fistula, including CD populations. Fistula drainage is needed before performing this surgical technique.

RESUMO

PURPOSE: The aim of the study was to explain the relationship between urinary stones and bowel disease. METHODS: A systematic review was performed on Medline, Embase and Cochrane using following keywords: urinary stones; urolithiasis; bowel; enteric and digestive. The literature selection was based on evidence and practical considerations. RESULTS: Fifty-three articles were selected. Three types of urolthiasis are mainly involved in digestive pathologies: calcium oxalate stones, uric acid and ammonium acid urate stones. Bowel pathologies responsible for stone disease are divided into small bowel diseases, colonic lesions and lack of an oxalate degrading bacteria (Oxalobacter formigenes) in the intestinal flora. Resulting in a decreased urine output, pH, hyperoxaluria, hypocitraturia or a hypomagnesurie. Blood and urinary explorations are the basis of diagnostic management. CONCLUSION: Bowel diseases can be responsible for urolthiasis. Understanding of the mechanisms, and metabolic evaluations can prevent recurrences. Increase fluid intake associated with specific supplementation and diet are the key of the treatment.
