Balloon-assisted endoscopic stricturotomy for small bowel fibrostenotic strictures: A comparison of Crohn’s disease-related and non-Crohn’s disease strictures

Figure 1 Flowchart of patient selection and grouping. CD: Crohn’s disease.

Figure 2 Representative techniques of endoscopic stricturotomy for small-bowel strictures. A: Narrow tubular stenosis in the ileum; B: Layered incision performed parallel to the bowel axis; C: Luminal patency restored after longitudinal incision; D: Circumferential narrowing of the ileum; E: Multiple radial incisions performed perpendicular to the stricture plane; F: Luminal patency restored after radial incision.

Figure 3 Reintervention-free survival following endoscopic stricturotomy in patients with small-bowel strictures. A: Kaplan-Meier curves comparing reintervention-free survival between patients with Crohn’s disease (CD)-related and non-CD small-bowel strictures; B: Kaplan-Meier curves stratified by neutrophil-to-lymphocyte ratio (NLR). Patients were categorized as low NLR (< 2.4) or high NLR (≥ 2.4). Shaded areas represent 95%CIs, and plus signs indicate censored observations. Survival curves were compared using the log-rank test. CD: Crohn’s disease; NLR: Neutrophil-to-lymphocyte ratio.
