Perianal complications of Crohn's disease are one of the significant reasons for abdominoperineal resection in patients with medically refractory perianal Crohn's disease. A 35-year-old man with Crohn's disease with colostomy presented to our clinic due to perianal fistulas. Complete stricture of the anus was observed, and the patient was found unsuitable for the stoma closure. The Turnbull-Cutait procedure was performed and he was discharged on the fifth postoperative day. In the second month after surgery, rectoscopy revealed a 2 cm long pouch on the neorectum. Then, the patient was treated with antibiotics and infliximab. Following the treatment, the symptoms of the patient were regressed. In the 10th postoperative month, a perianal abscess was seen, and the patient was treated with antibiotics. His ileostomy was reversed in the 18th postoperative month without any complications. In the 42nd postoperative month, no complications were reported. This case report presents the index perianal Crohn's disease case successfully treated with the Turnbull-Cutait procedure.

Crohn's perianal fistulas (CPF) are difficult to manage and often require multiple interventions. This study aimed to assess the preferences of patients and healthcare professionals (HCPs) for attributes of CPF-related procedures/surgeries to better inform CPF management.

This US cross-sectional, observational study was conducted via a web-enabled questionnaire (October 2021-January 2022) among patients aged 21-89 years with a self-reported physician diagnosis of CPF (with or without CPF-related surgery experience) and HCPs (gastroenterologists and colorectal surgeons who managed ≥3 patients with CPF in the past 12 months). Patient and HCP preferences for CPF-related procedure/surgery attributes were assessed using a discrete choice experiment and stated preference methodology.

In total, 100 patients and 137 HCPs were recruited. Benefits of therapy (symptom control and/or fistula closure) were rated as the most important CPF treatment attribute by both patients and HCPs influencing treatment decisions (mean relative importance 23.9 and 36.3, respectively). The mean relative importance of procedure invasiveness and postoperative discomfort was higher for patients (19.3 and 20.2, respectively) than for HCPs (14.3 and 11.0, respectively), whereas the mean relative importance of fecal incontinence was greater for HCPs than patients (25.0 vs. 19.3, respectively).

Patients and HCPs have different perspectives on the importance of specific CPF-related procedure/surgery attributes. The attributes identified as important to patients and HCPs in this study should be considered when managing patients with CPF and making treatment decisions.

Crohn disease perianal fistulas are associated with considerable morbidity and impaired quality of life. Nurses who specialize in inflammatory bowel disease (IBD) play a vital role in the management of Crohn disease perianal fistulas from diagnosis to long-term care; however, there is little evidence available to inform Crohn associated perianal fistula management strategies for nurses. This narrative review aims to provide IBD nurses with an up-to-date overview of Crohn perianal fistulas. It discusses the vital role IBD nurses play within the multidisciplinary team; the physical, social, and psychological impacts of Crohn perianal fistulas on patients; available treatment options; and how IBD nurses can support patients in their perianal fistula journey to enable optimum outcomes for patients. It also reviews diagnostic techniques and IBD nurses' involvement in Crohn perianal fistula diagnosis. While this article is aimed at IBD nurses, it is relevant to all nurses irrespective of their role (unit, clinic, community, and stoma) who interact with patients with Crohn perianal fistulas because awareness of the signs and symptoms of this condition will enable timely referrals and diagnosis.

Anal fistula has been a challenging clinical issue for years due to its complex pathogenesis. The risk of frequent recurrence and incontinence complicates long-term treatment. Recent scientific literature has reviewed new techniques used for anal fistula treatment in recent years, assessing the advantages and disadvantages of each based on clinical outcomes. Although surgery is the main method used to treat anal fistula, there is no simple technique that can completely heal complex anal fistula. The surgical treatment should consider the healing outcome and the protection of anal function comprehensively. Several innovative techniques have emerged in recent years, such as combined techniques based on drainage seton and LIFT-plug, which appear to be relatively effective therapies. However, more multi-center prospective trials with long-term follow-up are needed to validate their effectiveness. In some situations, medical treatment may also be considered.

Managing complex perianal fistulizing Crohn's disease (CD) remains challenging, despite current medical and surgical treatment approaches. Darvadstrocel, a therapy utilizing adipose-derived stem cells, shows promise in promoting tissue regeneration and healing, offering a novel and effective treatment for fistula management.

A systematic literature search was conducted on PubMed and Scopus to identify studies involving patients with complex perianal fistulizing CD treated with darvadstrocel.

In total, 2 randomized controlled trials (RCT), 5 observational studies with retrospective data collection and 2 observational studies with prospective design were included in the final review. Data from the European ADMIRE-CD RCT demonstrated that darvadstrocel is superior to placebo in terms of clinical and imaging improvement over both the short and long term. These findings align with the prospective studies analyzed in this systematic review. The rate of treatment-emergent adverse events in the ADMIRE-CD trial's RCTs was similar in both the darvadstrocel and control groups, with perianal abscess being the most common adverse event up to 52 weeks after drug administration. Retrospective studies indicated no side-effects beyond 52 weeks.

Darvadstrocel appears to be a new, potentially effective and safe treatment option for the management of complex perianal fistulas. However, more randomized clinical trials are needed to evaluate the efficacy and safety profile of the drug.

Perianal fistulas (PAFs) represent a severe complication of Crohn's disease (CD). Despite the advent of biologic and small-molecule therapeutics for luminal disease, PAFs in CD (CD-PAF) are relatively resistant to treatment, with less than 50% responding to any therapy. We report an injectable, biodegradable, mechanically fragmented nanofiber-hydrogel composite (mfNHC) loaded with adipose-derived stem cells (ADSCs) for the treatment of fistulas in a rat model of CD-PAF. The ADSC-loaded mfNHC results in a higher degree of healing when compared to surgical treatment of fistulas, which is a standard treatment. The volume of fistulas treated with mfNHC is decreased sixfold compared to the surgical treatment control. Molecular studies reveal that utilization of mfNHC reduced local inflammation and improved tissue regeneration. This study demonstrates that ADSC-loaded mfNHC is a promising therapy for CD-PAF, and warrants further studies to advance mfNHC toward clinical translation.

Diagnosis and management of inflammatory bowel diseases [IBD] requires a lifelong multidisciplinary approach. The quality of medical reporting is crucial in this context. The present topical review addresses the need for optimised reporting in endoscopy, surgery, and histopathology.

A consensus expert panel consisting of gastroenterologists, surgeons, and pathologists, convened by the European Crohn's and Colitis Organisation, performed a systematic literature review. The following topics were covered: in endoscopy: [i] general IBD endoscopy; [ii] disease activity and surveillance; [iii] endoscopy treatment in IBD; in surgery: [iv] medical history with surgical relevance, surgical indication, and strategy; [v] operative approach; [vi] intraoperative disease description; [vii] operative steps; in pathology: [viii] macroscopic assessment and interpretation of resection specimens; [ix] IBD histology, including biopsies, surgical resections, and neoplasia; [x] IBD histology conclusion and report. Statements were developed using a Delphi methodology incorporating two consecutive rounds. Current practice positions were set when ≥ 80% of participants agreed on a recommendation.

Thirty practice positions established a standard terminology for optimal reporting in endoscopy, surgery, and histopathology. Assessment of disease activity, surveillance recommendations, advice to surgeons for operative indication and strategies, including margins and extent of resection, and diagnostic criteria of IBD, as well as guidance for the interpretation of dysplasia and cancer, were handled. A standardised report including a core set of items to include in each specialty report, was defined.

Interdisciplinary high-quality care requires thorough and standardised reporting across specialties. This topical review offers an actionable framework and practice recommendations to optimise reporting in endoscopy, surgery, and histopathology.

As one of the clinical manifestations of inflammatory bowel disease (IBD), perianal fistula disease (PFD) can potentially impact the patient quality of life. The management of PFD employs a multidisciplinary approach which includes antibiotics, biological therapies, immunomodulators, and surgery. We analyzed the outcome and prognostic factors of anal fistula surgery in IBD patients.

We conducted a retrospective study of IBD patients undergoing elective surgery for anal fistula between January 2015 and December 2018 at our University Department of Surgery. We collated demographic factors, disease activity, imaging (MRI and endoanal ultrasound), surgical interventions, and medical treatment assessing the rate of fistula closure and fecal incontinence, 2 months and 1 year after surgery.

Thirty-five IBD patients with anal fistula underwent surgery (28 Crohn's disease, four ulcerative colitis, and three indeterminate colitis). Twenty-seven patients presented with complex fistulas and eight with simple fistulas with 10 patients undergoing single-stage surgery. In 25 patients, a two-stage surgical approach was planned and performed (draining seton plus medical treatment and then second-stage surgery with curative intent). At 1 year of follow-up, the fistula healing rate was 50% for single-stage surgery and 60% for two-stage surgery (P = 0.09). Overall, 19.2% of patients developed postoperative fecal incontinence. A time interval greater than 12 months between surgeries is a favorable prognostic factor for fistula healing with the two-stage approach (P = 0.002).

In our retrospective study, two-stage surgery in IBD patients presenting with complex perianal fistulous disease results in a better medium-term outcome with a longer time interval between surgeries.

Perianal fistulizing Crohn's disease is associated with a poor quality of life and current medical and surgical treatment options are limited. Darvadstrocel, composed of mesenchymal stem (stromal) cells (MSC), has recently been approved by the European Medicines Agency (EMA) for the treatment for perianal disease. This drug profile educates the reader with this novel treatment approach.

A literature search was performed on PubMed with focus on perianal fistulizing Crohn's disease and mesenchymal stem (stromal) cells. This review summarizes evidence of the current standard of care and discusses the mechanism of action, manufacturing, and application and safety of darvadstrocel.

Darvadstrocel is a safe and effective therapy for complex perianal fistulizing Crohn's disease.
