Total fistula volume predicts surgical outcomes in complex perianal fistulizing Crohn's disease following fistula-tract laser closure: a single-center retrospective study.
Backgrounds: This study aimed to identify risk factors influencing long-term treatment outcomes in patients with complex perianal fistulizing Crohn's disease (pfCD) following fistula-tract laser closure (FiLaC™).
Methods: A retrospective analysis was conducted on data from patients with complex pfCD who underwent FiLaC™ from January 2019 to December 2020, including demographics, pharmacological regimens, and preoperative MRI assessments. Follow-up monitored fistula outcomes such as healing, remission, failure, and recurrence.
Results: Among 49 patients followed for an average of 60.0 months, 31 (63.3%) achieved fistula healing, 3 (6.1%) showed improvement, 3 (6.1%) had non-healing, and 12 (24.5%) experienced recurrence. Significant differences were found between healed and unhealed groups in total fistula volume (TFV), number of fistula tracts, and perianal Crohn's disease activity index (PDAI) (P = 0.036, P = 0.020, and P = 0.041, respectively). Multivariate regression analysis indicated TFV as a significant predictor of healing outcomes (P = 0.013). ROC analysis confirmed its predictive value for fistula healing in complex pfCD, with an area under the curve (AUC) of 0.729 (P = 0.008). The optimal threshold for TFV was 4.81 cm3, with a sensitivity of 61.1% and a specificity of 83.9%. The AUC for recurrence rates was 0.883 (P < 0.001), with sensitivity and specificity at 83.3% and 83.8%, respectively, using the same threshold for TFV. The Kaplan-Meier survival curve highlighted the predictive potential of TFV for fistula recurrence (P < 0.0001).
Conclusions: TFV is an effective predictor of long-term outcomes in patients with complex pfCD following FiLaC™.
期刊介绍：
Techniques in Coloproctology is an international journal fully devoted to diagnostic and operative procedures carried out in the management of colorectal diseases. Imaging, clinical physiology, laparoscopy, open abdominal surgery and proctoperineology are the main topics covered by the journal. Reviews, original articles, technical notes and short communications with many detailed illustrations render this publication indispensable for coloproctologists and related specialists. Both surgeons and gastroenterologists are represented on the distinguished Editorial Board, together with pathologists, radiologists and basic scientists from all over the world. The journal is strongly recommended to those who wish to be updated on recent developments in the field, and improve the standards of their work.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1965 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted. Reports of animal experiments must state that the Principles of Laboratory Animal Care (NIH publication no. 86-23 revised 1985) were followed as were applicable national laws (e.g. the current version of the German Law on the Protection of Animals). The Editor-in-Chief reserves the right to reject manuscripts that do not comply with the above-mentioned requirements.
