Association of appendectomy with disease phenotype and clinical course in Crohn's disease: results from two cohorts.
Background: The appendix, as a component of the digestive system, plays a role in intestinal immunity.
Objective: To investigate the association between appendectomy history and disease phenotype/progression in Crohn's disease patients.
Design: Two cohorts from a single center.
Patients: Patients with Crohn's disease diagnosed between 2011 and 2021, including those without surgery and those undergoing their first surgery for Crohn's disease.
Methods: Patients were divided into surgical and non-surgical cohorts, each further split into appendectomy and non-appendectomy groups.
Results: In the non-surgical cohort, significant phenotypic disparities were observed between appendectomy-only and non-appendectomy groups across Montreal classification parameters, including age (p < 0.001), location (p = 0.03), and behavior (p = 0.01), with reduced perianal lesion prevalence in appendectomy patients (15% (9/60) vs. 35.7% (162/454), p = 0.001). Appendectomy patients exhibited later disease onset (IQR36 vs. 24 years, p < 0.001) and diagnosis (IQR37 vs. 26 years, p < 0.001). In the surgical cohort, significant differences emerged among non-appendectomy, appendectomy-only, and ileocecal resection groups in Montreal classification parameters: age at diagnosis (p = 0.014), location (p < 0.001), and behavior (p = 0.003). Disease progression timelines differed markedly, with later onset (IQR 29 vs. 27 vs. 25 years, p < 0.001), diagnosis (IQR 31 vs. 30 vs. 27 years, p < 0.001), and surgery (IQR 35 vs. 33 vs. 31 years, p < 0.001) observed in appendectomy-only patients. Surgical management varied significantly, including diagnosis-to-surgery intervals (mean 3.4 vs. 2.6 vs. 3.7 years, p < 0.001), perianal lesion (29.3% (123/420) vs. 24.4% (39/160) vs. 35.3% (173/490), p = 0.02), and one-stage surgery (36.2% (152/420) vs. 75.6% (120/160) vs. 66.1% (324/490), p < 0.001).
Limitations: Retrospective analysis with potential data biases.
Conclusion: Despite notable differences in disease phenotype, appendectomy does not seem to influence the clinical course of Crohn's disease. However, it seems to be associated with the lower risk of perianal disease and alleviates the severity of their condition.
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. Authors will be held responsible for false statements or for failure to fulfill such requirements.
