Background and Aim: Resection for Crohn's disease (CD) related strictures is definitive but carries risk of morbidity, recurrence, and short bowel syndrome. On the contrary, the durability of endotherapy (ET) for CD‐related strictures is questionable. Prospective comparative studies are limited. We aimed to prospectively compare the outcomes of ET in CD strictures with a case‐matched surgical therapy (ST) cohort. Methods: Patients undergoing ET or resection for primary CD strictures (symptomatic, non‐traversable, < 5 cm length, n ≤ 3) between January 2021 and March 2022 in a high‐volume tertiary center were compared with regard to recurrent symptoms, escalation of therapy, re‐intervention, and re‐operation based on propensity matched analysis. Results: Fifty‐nine patients [49% ET, 57.6% male, median (years): 34 (15–74)] had ≥ 12 months of follow up. Before propensity matching, cumulative re‐intervention rate was significantly higher with ET [34.5% (10/29) vs 3.3% (1/30) ST, P = 0.002]. Recurrent symptoms (34.5% vs 26.7%, P = 0.42), escalation of medical therapy (27.5% vs 23.3%, P = 0.64), and re‐operation (7.4% vs 3.1%, P = 0.55) were comparable. In propensity matched analysis adjusted for demographics, disease, and stricture characteristics [n = 42, 21 each, 62% male, median (years): 32 (15–60)], cumulative probability of re‐intervention rates was higher in ET (28.6% vs 4.8%, P = 0.042). The cumulative probability of recurrent symptoms (ET: 33.3% vs surgery 33.3%, P = 0.93), therapy escalation (ET: 23.8% vs surgery 28.6%, P = 0.75), and re‐operation (ET: 9.5% vs surgery 4.8%, P = 0.57) was similar. Conclusions: ET for CD strictures require higher re‐interventions compared with resection although re‐operation could be avoided in the majority with comparable symptom free survival at 1 year.

Background and Aim: We aim to evaluate the efficacy and safety of endoscopic radial incision (ERI) versus endoscopic balloon dilation (EBD) treatment of naïve, recurrent, and refractory benign esophageal anastomotic strictures. Methods: One hundred and one ERI, 145 EBD, and 42 ERI combined with EBD sessions were performed in 136 consecutive patients with benign esophageal anastomotic stricture after esophagectomy at Zhongshan Hospital from January 2016 to August 2021. Baseline characteristics, operational procedures, and clinical outcomes data were retrospectively evaluated. Parameters and recurrence‐free survival (RFS) were compared between ERI and EBD in patients with naïve or recurrent or refractory strictures. Risk factors for re‐stricture after ERI were identified using univariate and multivariate analyses. Results: Twenty‐nine ERI versus 68 EBD sessions were performed for naïve stricture, 26 ERI versus 60 EBD for recurrent strictures, and 46 ERI versus 17 EBD for refractory stricture. With comparable baseline characteristics, RFS was greater in the ERI than the EBD group for naïve strictures (P = 0.0449). The ERI group had a lower 12‐month re‐stricture rate than the EBD group (37.9% vs 61.8%, P = 0.0309) and a more prolonged patency time (181.5 ± 263.1 vs 74.5 ± 82.0, P = 0.0233). Between the two interventions, recurrent and refractory strictures had similar RFS (P = 0.0598; P = 0.7668). Multivariate analysis revealed initial ERI treatment was an independent predictive factor for lower re‐stricture risk after ERI intervention (odds ratio = 0.047, P = 0.001). Few adverse events were observed after ERI or EBD (3.0% vs 2.1%, P = 0.6918). Conclusions: ERI is associated with lower re‐stricture rates with better patency and RFS compared with EBD for naive strictures. [ABSTRACT FROM AUTHOR]

Background and Aim: There have been studies on risk factors for stenosis after pyloric endoscopic submucosal dissection (ESD). However, the most appropriate strategies for the management of cases with these risk factors have not been established. This study aimed to investigate post‐ESD management by evaluating the timing of stenosis and the effectiveness of endoscopic balloon dilation (EBD) after pyloric ESD. Methods: We retrospectively reviewed cases of pyloric ESD. We first reassessed risk factors for stenosis in multivariate analysis and receiver operating characteristic curve and defined patients with the identified risk factors as the risk group. The primary outcome was the timing of stenosis in the risk group assessed by the Kaplan–Meier method. Results: We reviewed 159 cases with pyloric ESD and observed pyloric stenosis in 25 cases. Cases with circumferential mucosal defect ≥ 76% were identified as the risk group. The stenosis‐free probability in the risk group was 97% (95% confidence interval [CI]: 79–100%), 94% (95% CI: 76–98%), and 85% (95% CI: 66–93%) on days 7, 14, and 21, respectively. It decreased every week thereafter and did not significantly change after day 56. Twenty‐three stenosis cases, except for conservative improvement, including six whole circumferential pyloric ESD cases, were improved by EBD without complications. Conclusions: Post‐ESD stenosis often developed from the third to the eighth week. In all pyloric ESD cases, including whole circumferential pyloric ESD cases, pyloric stenosis was improved following EBD without complications. [ABSTRACT FROM AUTHOR]

Abstract: Crohn's disease (CD) is a chronic relapsing and remitting disease that can affect any segments of the gastrointestinal tract. More than 50% of patients with CD develop stricturing or penetrating complications within the first 10 years after diagnosis. Strictures can lead to intestinal obstruction, which is a common indication for surgery. Despite significant advances in the understanding of the pathogenesis of intestinal fibrostenosis, imaging and therapeutic armamentarium of CD, the risk of intestinal surgery remained significantly high. Endoscopic balloon dilation is a promising first‐line alternative to surgery as it is less invasive and could preserve intestinal length. In this review, we will evaluate the literature on the mechanism of intestinal fibrosis, emerging imaging techniques, and management strategies for CD associated strictures. [ABSTRACT FROM AUTHOR]
