Complex perianal fistula is a common complication of Crohn's disease (CD) which leads to negative impact on patient's quality of life. Successful management of the disease requires a multidisciplinary approach, including a gastroenterologist and a colorectal surgeon, applying combined surgical and medical therapy. One of frequently practiced surgical procedures is seton placement in the fistula tract, which is used to control perianal sepsis and drain the fistula, while preventing recurrent abscess formation.Darvadstrocel, a suspension of expanded, allogeneic, adipose-derived, mesenchymal stem cells, is safe and effective for treatment-refractory complex perianal fistulas in patients with Crohn's disease. Following approval of darvadstrocel, the INSPIRE registry is being conducted in order to evaluate long-term safety and effectiveness of the drug on a large, heterogenous population.An online expert meeting was held from March 20 to March 30, 2023, which provided relevant insights into the decision-making process regarding seton use and obtained feedback on the first experiences with darvadstrocel. The aim of this article is to present the perspectives from gastroenterologists and colorectal surgeons practicing in Czechia, Hungary, Israel, Lithuania, Serbia, and Slovenia in topics such as diagnosis and treatment options for patients with complex Crohn's perianal fistulas (CPF), specifically focusing on the use of setons and darvadstrocel.During this virtual session, unavailability of comprehensive data on safety and efficacy of available treatment procedures was emphasized as an important obstacle towards development of standardized recommendations and improvement of outcomes in treatment of (CPF). Furthermore, achieving consensus in seton use, duration of its placement, and frequency of change is recognized as one of CPF treatments major challenges. Despite these issues, it is important to promote better understanding and treatment of complex perianal fistulas in order to improve the quality of life of those affected by this condition., (© 2024.

Introduction: The incidence of inflammatory bowel disease is increasing worldwide and, despite advances in conservative and surgical treatment, a significant proportion of patients do not achieve complete remission and have to undergo repeated surgical procedures. Stem cell therapy is a new alternative to immunomodulatory therapy., Methods: We performed a systematic review of the literature dealing with the use of mesenchymal stem cells for the treatment of IBD. The PubMed database was searched and original studies published between 2015 and 2021 were included., Results: A total of 80 citations were found, of which 21 clinical studies and 47 experimental studies were included in the review., Conclusion: The efficacy of MSCs in the treatment of perianal Crohns disease is at least comparable to current therapies. A positive effect of MSC administration has also been demonstrated in animal models of luminal disease or enterocutaneous fistula. The results after systemic administration in IBD patients are still ambiguous., Key Words: inflammatory bowel disease.

Introduction: Perianal hidradenitis suppurativa is a chronic recurrent inflammatory, suppurative, and fistulising disease of apocrine glands, adjacent anal canal and soft tissues. Perianal area is the second most common affected area after axilla. There are three grades of the disease. Hidradenitis suppurativa represents a chronic, recurrent, deep-seated folliculitis resulting in abscesses, followed by the formation of sinus tracts and subsequent scarring. Perianal hidradenitis suppurativa is the last and the most serious grade of the disease and a specific access is needed for patient preparation and surgical treatment alone. The currently preferred method of treatment for patients with extensive perianal hidradentitis is excision and closure with combination of skin flaps, primary suture and skin graft in one or two stages., Case Reports: There are three case reports of perianal hidradenitis suppurativa in this article. The local and overall initial treatment of patients followed by a radical excision and closure with a rotation skin flaps and skin grafts is described. The final results were satisfactory, with no recurrence or serious complication.

Introduction: Crohns disease is a chronic inflammatory autoimmune disease with unknown etiology. Although the disease may involve any part of the gastrointestinal tract, the most frequently affected site is the terminal ileum. Crohns disease itself is more common in women and in younger patients. Typical symptoms of the condition are diarrhoea, abdominal pain, weight loss and fever. A part of patients may present with extraintestinal symptoms like exanthema, joint pain, conjunctivitis or less often a hepatic lesion. In our publication, we have reported a rare case of Crohns disease with isolated involvement of the appendix, in which the definitive diagnosis was established after the surgery., Case Report: Our patient presented with atypical symptoms and endoscopy findings. The majority of patients with Crohns disease of the appendix present as if they had acute appendicitis., Conclusion: Appendiceal form of Crohns disease is a relatively rare variety of Crohns disease and is less aggressive than in the other locations. Surgical resection (appendectomy) is considered to be curative and the risk of relapse is very low. Key words: Crohns disease - appendix differential diagnosis - treatment surveillance.
