Background and aims: Limited evidence exists regarding the impact of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on upper endoscopy. Therefore, a meta-analysis was conducted to comprehensively review the available evidence on this subject.

Methods: A systematic bibliographic search was carried out until May 2024. Pooled estimates were analyzed using a random-effects model, with results presented as odds ratio (OR) and 95% confidence interval (CI). The primary outcome assessed was the rate of retained gastric content (RGC), while secondary outcomes included rates of aborted and repeated procedures, adverse event rate, and rates of aspiration.

Results: This analysis included 13 studies involving a total of 84,065 patients. Patients receiving GLP-1RA therapy exhibited significantly higher rates of RGC (OR, 5.56; 95% CI, 3.35 to 9.23), a trend that was consistent among patients with diabetes (OR, 2.60; 95% CI, 2.23 to 3.02). Adjusted analysis, accounting for variables such as sex, age, body mass index, diabetes, and other therapies, confirmed the elevated rates of RGC in the GLP-1RA user group (adjusted OR, 4.20; 95% CI, 3.42 to 5.15). Furthermore, rates of aborted and repeated procedures were higher in the GLP-1RA user group (OR, 5.13; 95% CI, 3.01 to 8.75; and OR, 2.19; 95% CI, 1.43 to 3.35; respectively). However, no significant differences were found in AE and aspiration rates between the 2 groups (OR, 4.04; 95% CI, 0.63 to 26.03; and OR, 1.75; 95% CI, 0.64 to 4.77; respectively).

Conclusion: Use of GLP-1RAs is associated with increased retention of gastric contents and more frequent aborted procedures during upper endoscopy. However, the adverse event and aspiration rates do not seem different; therefore, adjusting fasting time instead of routinely withholding GLP-1RAs could be reasonable in these patients.

Background & aims: Perianal fistulation is a challenging phenotype of Crohn's disease, with significant impact on quality of life. Historically, fistulae have been classified anatomically in relation to the sphincter complex, and management guidelines have been generalized, with lack of attention to the clinical heterogenicity seen. The recent 'TOpClass classification system' for perianal fistulizing Crohn's disease (PFCD) addresses this issue, and classifies patients into defined groups, which provide a focus for fistula management that aligns with disease characteristics and patient goals. In this article, we discuss the clinical applicability of the TOpClass model and provide direction on its use in clinical practice.

Methods: An international group of perianal clinicians participated in an expert consensus to define how the TOpClass system can be incorporated into real-life practice. This included gastroenterologists, inflammatory bowel disease surgeons, and radiologists specialized in PFCD. The process was informed by the multi-disciplinary team management of 8 high-volume fistula centres in North America, Europe, and Australia.

Results: The process produced position statements to accompany the classification system and guide PFCD management. The statements range from the management of patients with quiescent perianal disease to those with severe PFCD requiring diverting-ostomy and/or proctectomy. The optimization of medical therapies, as well as the use of surgery, in fistula closure and symptom management is explored across each classification group.

Conclusion: This article provides an overview of the system's use in clinical practice. It aims to enable clinicians to have a pragmatic and patient goal-centered approach to medical and surgical management options for individual patients with PFCD.
