RESUMO
PURPOSE: The efficacy of the novel SphinKeeper® procedure for the treatment of fecal incontinence (FI) is not yet well defined. This study aimed to assess long-term functional outcomes after SphinKeeper® surgery. METHODS: We included 32 patients with FI (28 female), who were operated at a tertiary referral center between August 2018 and September 2021. Functional outcome and quality of life were evaluated prospectively using validated questionnaires before and after surgery. Additionally, endoanal ultrasound and anal manometry were conducted prior and after SphinKeeper® implantation. Predictive parameters for treatment success were defined. RESULTS: The mean follow-up time was 22.62 ± 8.82 months. The St. Mark's incontinence score decreased significantly after surgery (median preoperative = 19 (IQR 17-22) versus median last follow-up = 12 (IQR 8-16), p = 0.001). Similarly, physical short-form health survey showed a significant improvement after SphinKeeper® implantation (p = 0.011). Patients with a higher degree of internal sphincter defect showed an improved objective therapy success (r = 0.633, p = 0.015) after SphinKeeper® operation, whereas the type and severity of FI had no impact on the functional outcome. Notably, a higher number of dislocated prostheses (r = 0.772, p = 0.015) showed a significant correlation with reduced improvement of incontinence. CONCLUSION: The SphinKeeper® procedure showed a significant long-term functional improvement in over half of the patients. Patients with a higher internal sphincter defect benefited most, whereas dislocation of the prostheses was associated with less favorable results.

The Sphinkeeper® procedure for treating faecal incontinence (FI) may be associated with potential implant migration (IM) and dislocation (ID), with considerable variations regarding their occurrence and effects on consecutive functional outcome. This study assessed IM and ID following the Sphinkeeper® procedure and its correlation with physical activity. This was a prospective observational clinical study of ten patients undergoing Sphinkeeper® operation due to FI between August 2020 and November 2020 at the Medical University of Vienna. Patients were followed-up after 1, 2, 3 and 6 months and 1 year postoperatively. Each follow-up visit included endosonographic monitoring of protheses location and manometric examinations. Additionally, functional outcome and physical activity were assessed using validated standardized questionnaires. The median number of prostheses implanted was 10 (IQR 9-10). The St. Mark's incontinence (SMS) score improved significantly until the last follow-up (p = 0.049), without observing a significant effect on the physical SF-12 score. The median rate of implants leading to IM and ID was 3 (range 1-4) and 2 (range 1-2) after 3 months of follow-up. A strong association of deltaSMS with number of dislocated prostheses at one month after Sphinkeeper® implantation was observed (r = 0.654, p = 0.078). Physical activity, assessed by the international physical activity questionnaire, did not have an impact on the correct prosthesis placement (1 month: p = 0.527; 2 months: p = 0.886; 3 months: p = 0.180; 6 months: p = 0.111). IM and ID of Sphinkeeper® prostheses occurred frequently early after surgery and affected functional outcome negatively. Physical activity did not have an influence on the implants displacement.

BACKGROUND: The use of mesenchymal stem cells is considered a novel and promising therapeutic option for patients with perianal fistulizing Crohn's disease; however, data on its clinical application remain scarce. This multicenter nationwide study aimed to assess the clinical efficacy of mesenchymal stem cells in closing complex anal fistulas. METHODS: In this study 14 Crohn's disease patients (3 males, 11 females) with complex anal fistulas treated in 3 tertiary hospitals in Austria were included between October 2018 and April 2021. Injection of 120 million allogeneic expanded adipose-derived mesenchymal stem cells (Cx601-darvadstrocel) was performed in each patient. Closure of the external fistula opening without secretion by external manual compression was defined as treatment success. RESULTS: The median age of the patient population at the time of surgery was 32 years (range 26-53 years) with a median body mass index of 21.7â¯kg/m2 (range 16.7-26.6â¯kg/m2). Of the patients 12 (86%) received monoclonal antibodies (infliximab, adalimumab, ustekinumab, vedolizumab) at the time of surgery. The median number of complex fistulas was 1.4 (range 1-2), The median operative time was 20â¯min (range 6-50â¯min) with no perioperative complications. After a median follow-up of 92 weeks, we found successful fistula closure in 57.1% (nâ¯= 8) of treated patients. The perianal disease activity index did not improve significantly from initially 7 to a median of 6 after 52 weeks (pâ¯= 0.495). CONCLUSION: Darvadstrocel is a safe, minimally invasive surgical technique without significant perioperative complications. Clinical success can be expected in about half of the treated patients.
RESUMO
(1) Background: The Sphinkeeper implantation for faecal incontinence (FI) is a novel surgical procedure with limited data on its clinical efficacy. Therefore, we aimed to assess the functional outcome following Sphinkeeper surgery in patients with refractory FI. (2) Methods: Between 2018 and 2020, eleven consecutive patients (9 female) with FI met the inclusion criteria and were enrolled for surgery. Functional outcome and quality of life were evaluated by standard questionnaires pre- and post-surgery. Migration of protheses was demonstrated by 3D endoanal ultrasound. The median follow-up time was eight months (range 3-18 months). (3) Results: The median age was 75 years (range 46-89 years) with a median BMI of 27.4 (range 21.2-30.1). The median number of implanted prostheses per intervention was nine (range 9-10). We found no intraoperative or early postoperative complications. After two months, two prostheses in one patient had to be removed due to pain at the perianal skin site. The median St. Mark's incontinence score decreased significantly from 22 to 13 points (p = 0.008). The SF-12 showed a significant improvement (35.9 versus 46.3) after surgery (p = 0.028). A migration of at least one prosthesis was observed in ten patients (91%). Six (60%) prostheses were found at the same level in another ten patients. (4) Conclusion: Sphinkeeper implantation is a promising surgical technique for patients with severe FI. The complication rate is low, and short-term functional improvement can be achieved even in severe forms of FI. Migration of implants commonly occurs.
