Introduction: Although endoscopic balloon dilation (EBD) is a common therapeutic approach for managing strictures associated with Crohn's disease (CD), the clinical application and complication rates of EBD remain unclear. Methods: We collected admission data for patients who underwent EBD using a nationwide database. We compared EBD outcomes between ileal and colonic strictures, CD and ulcerative colitis, and CD and anastomotic strictures arising from cancer‐related surgery. Subsequently, propensity score matching was employed to facilitate comparisons between each group. Results: The median duration of hospital stay was 4 days. Endoscopic hemostasis and urgent surgery rates after EBD for CD‐related strictures were considerably low (0.035% and 0.11%, respectively). Most patients with CD underwent only one EBD procedure during a single admission. Although no significant differences in patient backgrounds and severe complications were observed between ileal and colonic stricture in CD, multiple EBD procedures were more commonly performed for ileal strictures than for colonic stricture. Moreover, EBD for ileal stricture was more frequently conducted in high‐volume centers than in low‐volume centers. Regarding severe complications after EBD, no significant differences were observed between CD‐related strictures and ulcerative colitis or anastomotic strictures related to cancer surgery. Conclusion: Our findings support the safe and effective use of EBD for both ileal and colonic strictures associated with CD. The clinical practice and safety outcomes of EBD for CD‐related strictures were comparable to those for strictures stemming from other etiologies. [ABSTRACT FROM AUTHOR]

Background: Anastomotic strictures following colectomy and proctectomy are a significant cause of benign lower gastrointestinal tract (LGIT) obstruction, with a reported incidence of up to 30%. Endoscopic interventions such as balloon dilation, stricturotomy, mechanical dilation, electrocautery incision, and stent placement are utilized for management. This meta-analysis aimed to evaluate the efficacy and safety of endoscopic interventions for the management of benign LGIT anastomotic strictures. Methods: Literature search was performed for published full-text articles using the Embase, Pubmed, Web of Sciences, and Cochrane databases for endoscopic management of anastomosis strictures and related terms including endoscopic balloon dilation (EBD), stricturotomy (EST), mechanical dilation, electrocautery incision (ECI), and stent placement. Results: A total of 1363 patients from 33 studies were included. The most common indication for anastomosis was colorectal cancer (92%). Overall technical success (ability to pass the endoscope) was achieved in 93% of cases, with immediate clinical success in 85% and sustained success in 81% at follow-up. ECI demonstrated the highest clinical success rates (98% immediate, 91% at the end of follow-up). Adverse events occurred in 6% of patients, most commonly perforation, which was most frequent with EBD. Stent placement showed high initial success but had issues with stent migration and adverse events. Conclusion: Overall, EBD and ECI were the most effective, with ECI showing the highest success rates. Despite its technical challenges, EST was both effective and safe. This study underscores the need for further prospective research comparing various endoscopic interventions to improve management strategies for LGIT anastomotic strictures. [ABSTRACT FROM AUTHOR]

Purpose Proctitis distal to colorectal anastomosis is rare and infrequently reported. We evaluated the incidence, symptoms, treatment, and potential risk factors associated with this condition. Methods We conducted a retrospective population-based cohort study in Västmanland County, Sweden. This investigation included all patients who underwent sigmoidectomy with colorectal anastomosis between 2008 and 2020. We excluded patients without an anastomosis and those with inflammatory bowel disease. Results Of the 546 patients identified, 233 fulfilled the inclusion criteria, of whom 26 (11.2%) developed proctitis distal to colorectal anastomosis. The most frequent symptoms included urgency (n=16, 61.5%), increased stool frequency (n=12, 46.2%), and anorectal pain (n=12, 46.2%). Endoscopic balloon dilation was performed in 20 cases (76.9%), with 10 requiring only a single therapeutic procedure. The median number of dilations was 3 (range, 1–8). Multivariable analysis revealed that surgery due to malignancy and emergency surgery were associated with elevated risk of proctitis. A subgroup analysis of patients who underwent surgery due to malignancy indicated that smoking (odds ratio, 3.9; 95% confidence interval, 1.1–14.0) and emergency surgery (odds ratio, 6.5; 95% confidence interval, 1.1–37.1) were also associated with increased proctitis risk. Conclusion Proctitis distal to colorectal anastomosis is not uncommon following sigmoidectomy. Patients undergoing emergency surgery or surgery due to malignancy and who had a history of smoking displayed an increased risk of developing proctitis. Due to the paucity of symptoms observed, particularly in patients with a diverting stoma, routine endoscopic rectal examination should be performed during follow-up after sigmoidectomy.

Background: An anastomotic stricture after colorectal surgery is principally managed by endoscopic balloon dilation (EBD). Although this intervention is effective, however, subsequent procedures or surgical interventions are often required. This study aimed to assess the long-term outcomes of EBD for anastomotic stricture arising from colorectal cancer surgery. Materials and methods: We analyzed 173 patients who received curative surgery for colorectal cancer at our hospital between January 2000 and December 2022 and had undergone EBD to manage anastomotic stricture. The medical records of these cases were retrospectively reviewed to assess the outcomes and risk factors for restenosis and permanent stoma. Results: Of the 173 study patients, 41 (23.7%) presented with restenosis with a median time to recurrence of 49 [37–150] days. The restenosis group was significantly younger (55.6 years versus 60.8 years), with a more prominent rectal location (80.5% versus 57.6%), a higher incidence of hand-sewn anastomosis (24.4% versus 5.3%), and a higher percentage of neoadjuvant radiotherapy (34.1% versus 5.3%, P < 0.001). Multivariable analysis indicated neoadjuvant radiotherapy (adjusted HR 2.48; 95% CI 1.03–5.95) and cerebral vascular disease (adjusted HR 6.97; 95% CI 2.15–22.54) as independent prognostic factors for restenosis. Fourteen patients (8.1%) required a permanent stoma due to treatment failure. All cases needing a permanent stoma were male (14 patients, 100%, P = 0.007) and this group had a higher rate of neoadjuvant radiotherapy, adjuvant chemotherapy, and hand-sewn anastomosis. Conclusion: Patients receiving neoadjuvant radiotherapy are most prone to restenosis after an EBD intervention to manage an anastomotic stricture. Neoadjuvant radiotherapy is also a strong risk factor for requiring a permanent stomas due to treatment failure. [ABSTRACT FROM AUTHOR]

Background/Aims Transabdominal ultrasonography (US) helps evaluate Crohn’s disease (CD) activity. We investigated whether the US could predict subsequent adverse outcomes for patients with CD in clinical remission. Methods This single-center retrospective study included patients with CD in clinical remission who underwent US between April 2011 and April 2021, focusing on the predictability of subsequent adverse outcomes within 5 years. We used the US-CD, which was calculated using multiple US findings. Predictive variables were assessed using Cox proportional hazards regression analysis, and the predictive value was evaluated using receiver operating characteristic curves. Results Seventy-three patients were included. During a median follow-up of 1,441 days (range, 41–1,825 days), 16.4% (12/73) experienced clinical relapse, 9.6% (7/73) required endoscopic balloon dilation (EBD), 58.9% (43/73) required enhanced treatment, and 20.5% (15/73) underwent surgery. In the multivariate analysis, US-CD was significantly associated with clinical relapse (P= 0.038) and the need for enhanced treatment (P= 0.005). The area under the receiver operating characteristic curve for predicting clinical relapse and the need for EBD was 0.77 and 0.81, respectively, with US-CD (cutoff value = 11), and that for requiring enhanced treatment was 0.74 with US-CD (cutoff value = 6). Patients with US-CD ≥ 11 demonstrated a significantly higher occurrence of clinical relapse (P= 0.001) and EBD (P= 0.002) within 5 years. Patients with US-CD ≥ 6 experienced a significantly higher likelihood of requiring enhanced treatment (P< 0.001) within 5 years. Conclusions High US-CD is associated with subsequent adverse outcomes in patients with CD.

Objective: There are several options for surgical management of subglottic stenosis, including endoscopic and open procedures. However, treatment algorithms, outcomes, and anesthetic management of subglottic stenosis during pregnancy are not well described. Data Sources: MEDLINE, EMBASE, and the Cochrane databases. Review Methods: A scoping review of management of subglottic stenosis during pregnancy was performed, and then reported in compliance with Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. Inclusion criteria consisted of those with subglottic or tracheal stenosis aged greater than 18 years, those in whom management was performed during pregnancy, and those who reported delivery related outcomes. Results: After systematic review and detailed search of 330 identified articles, 15 articles met inclusion criteria and were included in the final analysis. All studies were case reports or case series (level 4 evidence). This study identified 27 patients. The median age was 29 and the median gestational age at intervention was 28 weeks. Left lateral positioning and fetal heart rate monitoring were used in nearly every case. The most common intervention performed was endoscopic balloon dilation. In many cases, jet ventilation or transnasal humidified rapid insufflation ventilatory exchange was satisfactory for maintenance of the airway. Three women ultimately required tracheostomy prior to labor and delivery. There was no fetal death or complications reported in these studies, and all but one woman proceeded to deliver at term. Conclusion: Endoscopic balloon dilation during pregnancy is safe and effective, resulting in optimized respiratory outcomes for the mother and safe delivery of the fetus. The third trimester appears to be safe for airway intervention. Laryngoscope, 134:1014–1022, 2024 [ABSTRACT FROM AUTHOR]

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.

Few studies have compared endoscopic balloon dilation (EBD) and surgery in the treatment of duodenal stricture in patients with Crohn's disease (CD). We performed a retrospective study to compare the efficacy and safety among patients with CD-associated duodenal stricture treated with EBD or surgery from October 2013 to December 2021. Univariate and multivariate analyses were performed to evaluate factors associated with recurrence-free or surgery-free survival. A total of 48 eligible patients were included, including 30 patients treated with EBD only and 18 patients treated with surgery. Patients treated with surgery experienced more symptomatic improvement (100% vs. 63.33%, p = 0.003) and significantly longer recurrence-free survival (6.31 [IQR: 3.00–8.39] years vs. 2.96 [IQR: 1.06–5.42] years, p = 0.01) but suffered more postprocedural adverse events (16.67% vs. 0.74% per procedure, p = 0.001). In patients initially treated with EBD (n = 41), a total of 11 (26.83%) required subsequent surgical intervention. Younger age at CD diagnosis (HR = 0.90, 95% CI: 0.81–1.00, p = 0.04) was associated with a higher risk for subsequent surgery. Surgery for CD-associated duodenal strictures was associated with a longer recurrence-free survival. EBD was safe and effective with minimal postprocedural adverse events but led to a high frequency of recurrence. [ABSTRACT FROM AUTHOR]

Objective: To compare the long-term effectiveness, complications, and outcomes of primary obstructive megaureter (POM) treated by endoscopic balloon dilation under fluoroscopic guidance versus not using radioscopy during the procedure. Patients and methods: A comparative study between POM cases treated at our institution by endoscopic balloon dilation (EBD) under fluoroscopic guidance (FG) (n = 43) vs no fluoroscopic guidance (NFG) (n = 48) between the years 2004 and 2018 was conducted. The procedure in FG consisted of performing a retrograde pyelography before dilation. Then, a guidewire is introduced to the renal pelvis, and the dilation of the vesicoureteral junction is performed using high-pressure balloon catheters under fluoroscopic vision. Finally, a double-J stent is placed between the renal pelvis and bladder. The procedure in NFG was performed exclusively under cystoscopic vision without radiological exposure. Complications, outcomes, and success rates were analyzed using Spearman's correlation test. Mean follow-up was 12.5 ± 2.2 years in FG and 6.4 ± 1.3 years in NFG. Results: MAG-3 showed significant differences in renal drainage before and after endoscopic treatment in both groups (p < 0.001 T-test). Statistical analysis did not reveal differences between groups in initial technical failure (r: − 0.035, p = 0.74), early postoperative complications (r: − 0.029, p = 0.79), secondary VUR (r: 0.033, p = 0.76), re-stenosis (r: 0.022, p = 0.84), long-term ureteral reimplantation (r: 0.065, p = 0.55), and final outcome (r: − 0.054, p = 0.61). The endoscopic approach of POM had a long-term success rate of 86.5% in FG VS 89.6% in NFG. Conclusions: Endoscopic balloon dilation of POM can be done with no radiation exposure with similar results, effectiveness, and outcomes. [ABSTRACT FROM AUTHOR]

Background: Interventional inflammatory bowel disease (IIBD) therapies can play a key role in inflammatory bowel disease (IBD) related stricture/fistula/abscess deferring or avoiding invasive surgery. Methods: A total of 112 studies pertaining to IIBD therapy for strictures/fistula/abscess between 2002 and December 2022 were included by searching Pubmed, Medline and Embase with a focus on technical/clinical success, recurrence, re-intervention and complications. Results: IIBD therapy for strictures include endoscopic balloon dilation (EBD), endoscopic stricturotomy (ES) and self-expanding metal stent (SEMS) placement. EBD is the primary therapy for short strictures while ES and SEMS can be used for refractory strictures. ES has higher long-term efficacy than EBD. SEMS is inferior to EBD although it can be useful in long, refractory strictures. Fistula therapy includes endoscopic incision and drainage (perianal fistula)/endoscopic seton (simple, low fistula) and endoscopic ultrasound-guided drainage (pelvic abscess). Fistulotomy can be done for short, superficial, single tract, bowel-bowel fistula. Endoscopic injection of filling agents (fistula plug/glue/stem cell) is feasible although durability is unknown. Endoscopic closure therapies like over-the-scope clips (OTSC), suturing and SEMS should be avoided for de-novo/bowel to hollow organ fistulas. Conclusion: IIBD therapies have the potential to act as a bridge between medical and surgical therapy for properly selected IBD-related stricture/fistula/abscess although future controlled studies are warranted.

Background/Aims With the growing multidisciplinary model of practice in the management of complex inflammatory bowel disease (IBD) and rising incidence of IBD, interventional IBD (IIBD) promises to play a key role. We aimed to evaluate current the role of IIBD in India and its short-term outcomes. Methods IBD patients undergoing IIBD procedures for stricture, bleeding, colitis-associated neoplasia, therapeutic small bowel endoscopy including retained capsule retrieval and postsurgical complications were enrolled prospectively between September 2021 and May 2022. Demographic and disease details, indications, initial and redo procedure details, technical/clinical success, and complications were recorded. Results IIBD procedures were performed in total 54 patients (61% males, median age: 37.5 years, range: 21–74 years, Crohn's disease [CD]: 42, ulcerative colitis [UC]: 12 between September 2021 and April 2022). Endoscopic balloon dilation (EBD) was performed in 44 patients (56 strictures, 9% anastomotic, 9% pouch) who underwent total 83 EBD procedures in 63 sessions. Short-term clinical efficacy after maximal dilation, technical success (i.e., scope passage after EBD), and complications (all mild) were noted in 95.4, 81.8, and 9.1%, respectively. Recurrent symptoms were seen in 27.3% on short-term follow-up (1–8 months, median: 5 months) for which redilation, surgery, and endoscopic stricturotomy were done in 22.7, 2.3, and 2.3% respectively. During small bowel EBD, motorized spiral enteroscopy-guided retained capsule endoscope retrieval was done in four patients. Ulcerative colitis-associated neoplasia (UCAN) was resected endoscopically in six patients (endoscopic submucosal dissection (ESD)—1, endoscopic mucosal resection (EMR)—5). High-grade dysplasia was resected in two patients (1 ESD for recurrent UCAN, 1 EMR had residual neoplasia on follow-up treated with underwater EMR). R0 resection was achieved in 83.3%. Endoscopic hemostasis was done with hemoclipping and sclerotherapy for UC-related bleeding in two, whereas a case of CD with proximal ileal bleeding was controlled with antegrade single-balloon enteroscopy-assisted hemoclipping. Conclusions IIBD is a promising modality in resource-limited settings like India acting as a bridge between medical therapy and surgery. Surgery can be avoided in a significant proportion with good short-term outcomes. Long-term outcomes need to be evaluated.

The most established treatments for achalasia are endoscopic balloon dilation (EBD) and laparoscopic Heller myotomy (LHM). This study aimed to compare the clinical outcomes and long-term quality of life of patients treated with EBD or LHM. Our study was a cross-sectional study on patients with idiopathic achalasia referred to the manometry center of Khorshid Hospital from 2018 to 2020. First, clinical and demographic data of patients were asked and supplemented by HRQOL (health-related quality of life questionnaire) and Eckardt questionnaires. In a 1-year follow-up, patients were called again and asked about the treatment choice (EBD or LHM), and clinical symptom improvement, quality of life, the asymptomatic period after treatment, and failure of the procedure were assessed. Of a total of 100 patients, 63 (63%) were men, and the mean age was 43.48 SD 8.76. The EBD procedure was conducted for 43 (43%). After 1 year of follow-up, the mean delta Eckardt score and the mean relative effect for Eckardt were significantly better for the LHM group. However, the mean delta HRQOL score and the mean relative effect for HRQOL for both groups were not significantly different. The total number of treatment failures was 9 (9%), which was significantly higher in the EBD group. The mean asymptomatic period after the procedure was significantly higher in the LHM group. Both EBD and LHM methods have a noticeable effect on symptom improvement, but LHM had better results in symptom improvement, treatment failure, and asymptomatic period time after the procedure.

The number of laparoscopic sleeve gastrectomies (LSGs) performed in patients with obesity who are eligible for bariatric and metabolic surgery is currently much lower in Japan than in other countries. Considering the large number of potential patients with obesity and type 2 diabetes and the unique Japanese national health insurance system that guarantees fair healthcare delivery, there is room to increase the number of LSGs in Japan in the near future. However, strict health insurance regulations may limit access to mandatory devices needed to treat postoperative complications, such as staple line leakage, which can cause severe morbidity and even mortality. Therefore, understanding the pathogenesis and treatment options for this complication is crucial. This article examined the current situation in Japan and its impact on staple line leakage management, including the role of endoscopic treatment in reducing reoperation. The authors suggest increasing education and collaboration between healthcare professionals to optimize management and improve patient outcomes. [ABSTRACT FROM AUTHOR]

Abstract Background Endoscopic balloon dilation (EBD) is an effective, minimally invasive treatment for Crohn's disease (CD) related intestinal strictures. However, restenosis frequently occurs and requires repetitive EBD or surgical resection. Since previous studies could not evaluate restenosis based on stricture diameter, factors affecting restenosis after EBD were unclear. This study aimed to identify these factors by precisely measuring the diameter of small intestinal strictures in patients with CD. Methods This single‐center retrospective study enrolled patients with CD with de novo small intestinal strictures who underwent two double‐balloon enteroscopy sessions (EBD and follow‐up) between January 2016 and October 2021. Clinical and endoscopic data were obtained from electronic medical records. A calibrated small‐caliber‐tip transparent hood was used to precisely measure stricture diameters. Multivariate analysis was performed to identify factors associated with restenosis. Results Forty‐eight patients (37 male) were analyzed. The total number of strictures detected decreased from 162 to 143. The mean diameter of all strictures and the narrowest stricture in each patient increased significantly from 8.6 to 9.8 mm and from 7.6 to 8.7 mm, respectively. Thirty‐two (67%) patients developed endoscopic restenosis. Multivariate analysis showed that the presence of ulcers at the follow‐up session was a risk factor for restenosis (odds ratio 9.4, p = 0.01). Patients with complete mucosal healing at both sessions (n = 21) showed significant improvement in the narrowest stricture (+1.7 mm, p = 0.001). Conclusions Maintenance of complete mucosal healing is significantly associated with avoiding restenosis after EBD in CD‐related small intestinal strictures.

Abstract Background Small intestinal stricture is a major cause for surgery in Crohn’s disease (CD). Endoscopic balloon dilation (EBD) is performed for small intestinal strictures to avoid surgery, often repeatedly. However, factors that are associated with prognosis after EBD of small intestinal strictures remain poorly investigated. Mucosal healing is the therapeutic target in CD. We aimed to investigate the impact of mucosal healing defined by the presence of ulcers at the small intestinal stricture site on the prognosis of EBD in CD patients. Methods We retrospectively included patients with CD who underwent initial EBD for endoscopically impassable small intestinal strictures from January 2012 to March 2020 at a single center. The association between presence of ulcer at the stricture site and surgery after EBD was examined by Cox proportional hazards model. Results Of the 98 patients included, 63 (64.3%) had ulcer at the stricture site. 20 (31.7%) of these patients underwent surgery for the stricture in due course, whereas 4 (11.4%) of the patients without ulcer of the stricture underwent surgery. In multivariate analysis, patients with ulcer of the stricture had a significantly higher risk for surgery than those without ulcer (hazard ratio 4.84; 95% confidence interval 1.58–14.79). Conclusion Mucosal healing at the stricture site indicated a favorable prognosis after EBD for small intestinal strictures in CD.

Background: Endoscopic balloon dilation (EBD) has emerged as an alternative intervention to manage Crohn's disease (CD) strictures. We determined the cost-effectiveness of EBD versus resection surgery for patients with short (< 4–5 cm) primary or secondary/anastomotic small or large bowel strictures. Methods: A microsimulation state-transition model analyzed the benefits and risks of EBD and resection surgery for patients with primary or anastomotic CD strictures. Our primary outcome was quality-adjusted life years (QALYs) over ten years, and strategies were compared using a willingness to pay of $100,000/QALY from a societal perspective. Costs (2021 $US) and incremental cost-effectiveness ratios (ICER) were calculated. Deterministic 1-way and probabilistic analyses assessed model uncertainty. Results: The EBD strategy cost $19,822 and resulted in 6.18 QALYs while the surgery strategy cost $41,358 and resulted in 6.37 QALYs. Surgery had an ICER of $113,332 per QALY, making EBD a cost-effective strategy. The median number of EBDs was 5 in the EBD strategy and 0 in the surgery strategy. The median number of surgeries was 2 in the surgery strategy and 1 in the EBD strategy. Of individuals who initially received EBD, 50.4% underwent subsequent surgery. One-way sensitivity analyses showed that the probabilities of requiring repeated interventions, surgery mortality (< 0.7%), and quality of life after interventions were the most influential model parameters. Probabilistic sensitivity analyses favored EBD in 50.9% of iterations. Conclusions: EBD is a cost-effective strategy for managing CD strictures. Differences in patient risk and quality of life after intervention impact cost-effectiveness. Intervention decisions should consider cost-effectiveness, patient risks, and quality of life.

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/Aims With the growing multidisciplinary model of practice in the management of complex inflammatory bowel disease (IBD) and rising incidence of IBD, interventional IBD (IIBD) promises to play a key role. We aimed to evaluate current the role of IIBD in India and its short-term outcomes. Methods IBD patients undergoing IIBD procedures for stricture, bleeding, colitis-associated neoplasia, therapeutic small bowel endoscopy including retained capsule retrieval and postsurgical complications were enrolled prospectively between September 2021 and May 2022. Demographic and disease details, indications, initial and redo procedure details, technical/clinical success, and complications were recorded. Results IIBD procedures were performed in total 54 patients (61% males, median age: 37.5 years, range: 21–74 years, Crohn's disease [CD]: 42, ulcerative colitis [UC]: 12 between September 2021 and April 2022). Endoscopic balloon dilation (EBD) was performed in 44 patients (56 strictures, 9% anastomotic, 9% pouch) who underwent total 83 EBD procedures in 63 sessions. Short-term clinical efficacy after maximal dilation, technical success (i.e., scope passage after EBD), and complications (all mild) were noted in 95.4, 81.8, and 9.1%, respectively. Recurrent symptoms were seen in 27.3% on short-term follow-up (1–8 months, median: 5 months) for which redilation, surgery, and endoscopic stricturotomy were done in 22.7, 2.3, and 2.3% respectively. During small bowel EBD, motorized spiral enteroscopy-guided retained capsule endoscope retrieval was done in four patients. Ulcerative colitis-associated neoplasia (UCAN) was resected endoscopically in six patients (endoscopic submucosal dissection (ESD)—1, endoscopic mucosal resection (EMR)—5). High-grade dysplasia was resected in two patients (1 ESD for recurrent UCAN, 1 EMR had residual neoplasia on follow-up treated with underwater EMR). R0 resection was achieved in 83.3%. Endoscopic hemostasis was done with hemoclipping and sclerotherapy for UC-related bleeding in two, whereas a case of CD with proximal ileal bleeding was controlled with antegrade single-balloon enteroscopy-assisted hemoclipping. Conclusions IIBD is a promising modality in resource-limited settings like India acting as a bridge between medical therapy and surgery. Surgery can be avoided in a significant proportion with good short-term outcomes. Long-term outcomes need to be evaluated. [ABSTRACT FROM AUTHOR]

Balloon‐assisted enteroscopy allows endoscopic treatments in the deeper segments of the small bowel. Endoscopic balloon dilation has become a popular minimally invasive alternative for the treatment of Crohn's disease‐associated small intestinal strictures. As a supplement to the Clinical Practice Guidelines for Enteroscopy, the Japan Gastroenterological Endoscopy Society's Working Committee has developed the present "Guidelines for endoscopic balloon dilation in treating Crohn's disease‐associated small intestinal strictures," based on new scientific techniques and evidence. The guidelines cover standard procedures for the insertion route of the balloon endoscope, bowel preparation, indications, procedure‐related complications, efficacy, target diameter and duration, management of multiple strictures, and the current state of combined and alternative treatments. Unresolved future research questions are also listed in this guideline. [ABSTRACT FROM AUTHOR]

Background: Managing refractory esophageal strictures (RES) presents formidable challenges. Although endoscopic balloon dilation (EBD) is the first step for esophageal stricture, the clinical outcomes of EBD for RES after esophageal atresia (EA) repair are not established., Methods: All EA patients with esophageal balloon strictures (EBS) from October 2016 to October 2022 treated by EBD in our institution were retrospectively reviewed. The primary endpoint was to evaluate the clinical outcomes and the risk factors for poor outcomes of EBD for RES. The secondary endpoint was to evaluate the risk factors for pathological weight in RES patients., Results: 87 patients with RES were included in our study. After the first session of EBDs, 40.2 % experienced a recurrence of esophageal strictures. The median number (IQR) of the first session of EBD was 13.0 (8.0, 16.0), and the median number (IQR) of total dilations of achieving long-term clinical success was 14.0 (10.0, 19.0) with 81.6 % achieving long-term clinical success with less than 20 EBDs. In follow-up, all patients achieved a total oral diet. On multivariable analysis, the presence of GERD (OR 4.17, 95%Cl 1.29-13.51, p = 0.017), LGEA (long-gap esophageal atresia) (OR 5.19, 95 % Cl 1.15-23.52, p = 0.033), eccentric stricture shape (OR 3.34, 95%Cl 1.06-10.53, p = 0.040), and longer stricture length (OR 10.22, 95%Cl 1.14-92.01, p = 0.038) were statistically significant associated with increased endoscopic dilations. The presence of LGEA (OR 3.25, 95%Cl 1.03-10.20, p = 0.044) was significantly associated with recurrence after short-term clinical success. Additionally, Older age at first dilation after LEAP, stricture level at 1/3 upper (ref = 1/3 middle), and LGEA were identified as risk factors for developing pathological weight., Conclusion: Endoscopic balloon dilation is an effective method for treating RES after EA repair. GERD, LGEA, eccentric stricture shape, and longer stricture length are the risk factors for increased dilation times. Older age at first dilation after LEAP, stricture level at 1/3 upper, and LGEA were identified as risk factors for developing pathological weight., (Copyright © 2024 Asian Surgical Association and Taiwan Society of Coloproctology.

Purpose: Proctitis distal to colorectal anastomosis is rare and infrequently reported. We evaluated the incidence, symptoms, treatment, and potential risk factors associated with this condition., Methods: We conducted a retrospective population-based cohort study in Västmanland County, Sweden. This investigation included all patients who underwent sigmoidectomy with colorectal anastomosis between 2008 and 2020. We excluded patients without an anastomosis and those with inflammatory bowel disease., Results: Of the 546 patients identified, 233 fulfilled the inclusion criteria, of whom 26 (11.2%) developed proctitis distal to colorectal anastomosis. The most frequent symptoms included urgency (n=16, 61.5%), increased stool frequency (n=12, 46.2%), and anorectal pain (n=12, 46.2%). Endoscopic balloon dilation was performed in 20 cases (76.9%), with 10 requiring only a single therapeutic procedure. The median number of dilations was 3 (range, 1-8). Multivariable analysis revealed that surgery due to malignancy and emergency surgery were associated with elevated risk of proctitis. A subgroup analysis of patients who underwent surgery due to malignancy indicated that smoking (odds ratio, 3.9; 95% confidence interval, 1.1-14.0) and emergency surgery (odds ratio, 6.5; 95% confidence interval, 1.1-37.1) were also associated with increased proctitis risk., Conclusion: Proctitis distal to colorectal anastomosis is not uncommon following sigmoidectomy. Patients undergoing emergency surgery or surgery due to malignancy and who had a history of smoking displayed an increased risk of developing proctitis. Due to the paucity of symptoms observed, particularly in patients with a diverting stoma, routine endoscopic rectal examination should be performed during follow-up after sigmoidectomy.

ABSTRACT BACKGROUND: Esophageal stenosis (ES) in children is a fixed intrinsic narrowing of the esophagus due to numerous aetiologies. OBJECTIVE: This study aimed to determine the clinical and nutritional impacts of endoscopic balloon dilation (EBD) in Iranian children with an esophageal stricture. METHODS: This retrospective study, pediatric patients (aged

Objective: Eustachian tube dysfunction (ETD) is a chronic entity that has been historically managed with adenoidectomy and ventilation tube insertion. Recently, balloon dilation of the eustachian tube has shown promising results in recalcitrant eustachian tube dysfunction. We reviewed the literature to determine the outcome of eustachian tube balloon dilation in children. Methods: A literature search was conducted for the period from 1990 to 2020 by searching several databases over a 1-month period (January 2021) according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Cochrane Handbook for Systematic Reviews for Interventions. Primary outcome was defined as the success of the intervention determined by the resolution of symptoms, and secondary outcome was determined by revisions surgery and presence of complications. Results: Only 7 articles were identified based on our objectives and selection criteria. All studies included are retrospective cohort case series (Level IV) and 1 cohort of matched controls (Level III). A total of 284 patients were included in this review, with a mean age of 7.8 years. A total of 463 balloon dilation were performed either bilaterally or unilaterally. The most common finding of ETD is middle ear effusion in 5 studies. Balloon dilation of eustachian tube was second-line treatment in 6 studies and first-line treatment in 1 study. Improvement of symptoms was identified in all studies through various assessments performed. Revision surgery was performed in 1 study with no major complications reported. Conclusions: Balloon dilation of the eustachian tube may be considered as an alternative procedure following failed standard treatment in children. The quality of evidence is inadequate to recommend widespread use of the technique until a better-quality study has been completed. Future randomized controlled studies with a large sample size are warranted to determine the efficacy of this procedure amongst children. [ABSTRACT FROM AUTHOR]

Small bowel evaluation is warranted in all newly diagnosed cases of Crohn’s disease (CD) as small bowel is involved in two-thirds of CD patients at diagnosis and the involvement can be discontinuous. Endoscopic evaluation of the small bowel in suspected or established CD can be done by video capsule endoscopy (VCE), device assisted enteroscopy (DAE) (which includes single and double balloon enteroscopy, novel motorized spiral enteroscopy (NMSE) and balloon guided endoscopy (BGE)) and intra-operative enteroscopy (IOE). In suspected CD with a negative ileo-colonoscopy, VCE is the preferred initial diagnostic modality in the absence of obstructive symptoms or known stenosis. VCE should be preceded by cross-sectional imaging or patency capsule testing if obstruction is suspected given with high retention risk. In established cases, small bowel cross-sectional imaging (magnetic resonance or computed tomography enterography) is preferred over VCE as it can assess transmural and extra-luminal involvement. VCE is indicated subsequently if necessary to assess disease extent, unexplained symptoms (e.g., anemia, malnutrition) or mucosal healing. Pan-enteric capsule endoscopy (PCE) and the use of artificial intelligence are the recent developments with VCE. DAE with small bowel biopsy can provide definitive evidence of CD including the extent and severity. A final diagnosis of CD is based on the constellation of clinical, radiologic, histologic and endoscopic features. Newer technologies like NMSE and BGE can help with deeper and faster small bowel evaluation. DAE has also allowed endoscopic treatment of small bowel strictures, small bowel bleeding and retrieval of retained capsule or foreign bodies. Endoscopic balloon dilation (EBD), endoscopic electro-incision, strictureplasty and stenting have shown promising results in CD related small bowel strictures. In conclusion, endoscopic evaluation of the small bowel is rapidly evolving field that has a major role in diagnosis and management of small bowel CD and can alter treatment outcomes in properly selected patients.

Background: Small intestinal stricture is a major cause for surgery in Crohn's disease (CD). Endoscopic balloon dilation (EBD) is performed for small intestinal strictures to avoid surgery, often repeatedly. However, factors that are associated with prognosis after EBD of small intestinal strictures remain poorly investigated. Mucosal healing is the therapeutic target in CD. We aimed to investigate the impact of mucosal healing defined by the presence of ulcers at the small intestinal stricture site on the prognosis of EBD in CD patients.Methods: We retrospectively included patients with CD who underwent initial EBD for endoscopically impassable small intestinal strictures from January 2012 to March 2020 at a single center. The association between presence of ulcer at the stricture site and surgery after EBD was examined by Cox proportional hazards model.Results: Of the 98 patients included, 63 (64.3%) had ulcer at the stricture site. 20 (31.7%) of these patients underwent surgery for the stricture in due course, whereas 4 (11.4%) of the patients without ulcer of the stricture underwent surgery. In multivariate analysis, patients with ulcer of the stricture had a significantly higher risk for surgery than those without ulcer (hazard ratio 4.84; 95% confidence interval 1.58-14.79).Conclusion: Mucosal healing at the stricture site indicated a favorable prognosis after EBD for small intestinal strictures in CD.

Esophageal endoscopic submucosal dissection can cause esophageal strictures. Endoscopic balloon dilation is the standard treatment for esophageal strictures, but has complications, including perforation, and sometimes requires surgery. We report a case of perforation during endoscopic balloon dilation for esophageal stricture secondary to esophageal submucosal dissection that was successfully treated conservatively. A 66-year-old man with superficial carcinoma in the upper thoracic esophagus underwent circumferential endoscopic submucosal dissection with local steroid injections. Endoscopic balloon dilation was performed weekly for esophageal stricture. However, during the sixth procedure, an attempt to increase the size of the balloon to 13.5 mm resulted in perforation. The patient was treated conservatively using polyglycolic acid sheet with fibrin glue at the perforation site, which was fixed using an endoclip. However, the esophageal stricture persisted after the perforation was closed and Endoscopic balloon dilation was carefully repeated twice weekly up to a maximum of 17 mm, and the endoscope was able to pass through, and associated symptoms improved. This report indicates that endoscopic tissue shielding using polyglycolic acid sheet with fibrin glue and endoclip to correct perforation, followed by additional endoscopic balloon dilation, is an alternative to surgery.

Abstract A 58‐year‐old man who had the history of alcohol dependence was referred to our emergency center due to severe nausea, vomiting, and subsequent onset of chest and back pain. Esophagogastroduodenoscopy (EGD) showed black‐appearing esophagus mucosa extending from the cervical esophagus to the esophagogastric junction with clear margins, a condition typically referred to as a black esophagus. Alcohol abuse was considered an important factor associated with acute esophageal necrosis in this patient. After admission, he received fluid resuscitation and proton‐pump inhibitors, with restriction of oral intake and treatment of alcohol dependence. Follow‐up EGDs and endoscopic balloon dilation were performed for the management of esophageal narrowing before the development of severe strictures. Strictures were successfully treated endoscopically without complications such as perforation.

• Esophageal stenosis improves after radiotherapy and ESD. • The frequency of grade 3 esophageal stenosis was low, and grade 3 esophageal stenosis improved to grade 2 or less by EBD. • No new ≥ grade 2 esophageal stenosis were observed 6 months after radiotherapy. • Cervical esophageal cancer is a risk factor for severe esophageal stricture after combined ESD and RT. Radiotherapy (RT) has recently received increasing attention as an additional treatment for organ preservation after non-curative endoscopic submucosal dissection (ESD) in patients with superficial esophageal cancer. Esophageal stenosis is an adverse event related to RT after ESD that is not widely studied. The aim of this study was to investigate esophageal stenosis related to salvage RT in superficial esophageal cancer after non-curative ESD. Fifty patients who received salvage RT after non-curative ESD at a single institution between 2011 and 2018 were included in this study. The Common Terminology Criteria for Adverse Events, version 5.0, was used to assess esophageal stenosis. Data were compared using Fisher's exact test. Statistical significance was set at P < 0.05. Median follow-up time was 48 months (range, 12–95 months). Grade 2 and 3 esophageal stenosis were observed in 17 (34%), and 3 patients (6%), respectively. The frequency of grade 2 or worse esophageal stenosis decreased over time (before RT, 6 months, 1 year, and 2 years after RT: 16 (32%), 13 (26%), 10 (20%), and 6 (12%) patients, respectively). Only one patient required endoscopic balloon dilation (EBD) 1 year after RT. All grade 3 esophageal stenosis improved grade 2 or less by EBD. In univariate analysis, only tumor location was a significant risk factor for grade 3 esophageal stenosis. Esophageal stenosis, after salvage RT in patients with esophageal cancer who received non-curative ESD, improved naturally or after EBD; only a few cases required long-term EBD.

ObjectivesTo evaluate the safety and efficacy of endoscopic treatment for congenital pediatric esophageal stenosis or pediatric stenosis that develops after a chemical burn or surgical repair of esophageal atresia.MethodsWe retrospectively reviewed the medical records of 15 pediatric patients who underwent endoscopic treatments (dilation and/or stenting and/or incision) for congenital esophageal stenosis or esophageal stenosis that developed after a chemical burn or surgical repair of esophageal atresia, between January 2010 and January 2019. The patients were periodically followed-up to assess the safety and efficacy of treatment by comparing the diameter of stricture and dysphagia score before and after procedures, and complications or recurrence.ResultsAll children successfully underwent the procedures. Fourteen of the 15 patients received endoscopic balloon dilation (EBD) as the first step of treatment, but EBD alone only resolved the symptoms in two patients. The remaining patients received other comprehensive treatments, such as EBD with endoscopic incision (EI), EBD with stent replacement, or a combination of EBD, stent replacement, and EI. Eleven (11/15, 73.3%) patients experienced symptomatic relief after endoscopic treatment, and recurrence was noted in four patients on 3–36 months after the final endoscopic treatment. All four patients underwent esophageal surgery to relieve their symptoms. Until October 2021, all patients experienced symptom relief, and their dysphagia scores decreased from 3–4 to 0–1 during the follow-up period of 8–121 months. The average diameter of stenosis was increased from 0.34 cm (range 0.2–0.7 cm) to 1.03 cm (range 0.8–1.2 cm). No severe complications occurred during endoscopic treatment and follow-up.ConclusionsEndoscopic treatment is safe and effective for pediatric esophageal stenosis that is congenital or induced by chemical burns or surgical repair of esophageal atresia. Comparative large-scale studies are required to confirm our findings.

Background: Successful Crohn's disease (CD) therapy relies on timely and precise management strategies. Endoscopic balloon dilation (EBD) has been applied as a first-line treatment for symptomatic CD-associated strictures due to its minimally invasive nature and the possibility of preserving intestinal length., Objective: The aim of the present study was to determine patient-related predictive factors associated with the need for surgery for CD-associated ileocolic strictures after technically successful EBD., Methods: All original studies published before December 2023 that reported the outcomes of patients treated with EBD for ileocolic strictures secondary to CD and described follow-up for at least 1 year were included. The difference in risk of needing surgery was calculated for 8 different patient characteristics (Sex, smoking habit, previous surgery, biologic therapy, steroids, immunosuppressors, nature of the stricture, and endoscopic disease activity)., Results: There were significant differences in the risk of needing surgery after EBD among patients who underwent surgery and patients without a history of surgery (RD: -0.20 [-0.31, -0.08]), patients with endoscopic mucosal activity and patients in remission at the time of EBD (RD: 0.19 [0.04, 0.34]), patients using biologics at the time of EBD and patients not using biologics (RD: -0.09 [-0.16, -0.03]), and patients using steroids and those not using steroids at the time of EBD (RD: 0.16 [0.07, 0.26])., Conclusions: The use of biologics and endoscopic disease remission at the time of EBD were protective factors against the need for surgery. No previous surgery or use of steroids at the time of EBD was associated with the need for surgery during follow-up., Competing Interests: None declared.

Interventional endoscopy can play a key role in the multidisciplinary management of complex inflammatory bowel disease (IBD) as an adjunct to medical and surgical therapy. The primary role of interventional IBD (IIBD) includes the treatment of Crohn's disease-related stricture, fistula, and abscess. Endoscopic balloon dilation (EBD), endoscopic stricturotomy, and placement of endoscopic stents are different forms of endoscopic stricture therapy. EBD is the most widely used therapy whereas endoscopic stricturotomy has higher long-term efficacy than EBD. Fully covered and partially covered self-expanding metal stents are useful in long and refractory strictures whereas lumen-apposing metal stents can be used in short, and anastomotic strictures. Endoscopic fistula/abscess therapy includes endoscopic fistulotomy, seton placement, endoscopic ultrasound-guided drainage of rectal/pelvic abscess, and endoscopic injection of filling agents (fistula plug/glue/stem cell). Endoscopic seton placement and fistulotomy are mainly feasible in short, superficial, single tract fistula and in those with prior surgical seton placement. Similarly, endoscopic fistulotomy is usually feasible in short, superficial, single-tract fistula. Endoscopic closure therapies like over-the-scope clips, suturing, and self-expanding metal stent should be avoided for de novo /bowel to hollow organ fistulas. Other indications include management of postoperative complications in IBD such as management of surgical leaks and complications of pouchitis in ulcerative colitis. Additional indications include endoscopic resection of ulcerative colitis-associated neoplasia (by endoscopic mucosal resection, endoscopic submucosal dissection, and endoscopic full-thickness resection), retrieval of retained capsule endoscope, and control of bleeding. IIBD therapies can potentially act as a bridge between medical and surgical therapy for properly selected IBD patients., Competing Interests: None declared., (© The Author(s) 2024.

Background: Crohn's disease (CD) is a chronic inflammatory condition of the gastrointestinal tract. Current drugs are not effective for treating the primary fibrotic component of CD. Recommended invasive treatments include endoscopic balloon dilation, surgery with resection, or strictureplasty. This meta-analysis compared invasive treatment techniques for CD-related strictures in the pediatric population., Methods: The MEDLINE, EMBASE, and LILACS databases were searched from inception to December 2023. This meta-analysis was performed as per the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The outcome was measured by the rate of stenosis recurrence and the adverse events of the techniques. Eligibility criteria were studies that involved the analysis of the recurrence rate of stenosis in pediatric patients with CD requiring surgical intervention after undergoing any of the previously proposed therapies. Additionally, adverse events were analyzed., Results: Three studies comprising a total of 106 endoscopic balloon dilations demonstrated a combined rate of stricture recurrence in patients with CD requiring surgical intervention of 0.171 (95% confidence interval [CI], 0.110-0.255). Three studies comprising a total of 49 surgical resections demonstrated a pooled event rate of 0.100 (95% CI, 0.038-0.240). Finally, 2 studies comprising a total of 38 strictureplasties demonstrated a pooled event rate of 0.347 (95% CI, 0.070-0.789). Concerning adverse events, the most common occurrences were found after surgical resection., Conclusions: Surgical resection is the best option for treating strictures in pediatric CD patients in terms of recurrence rate, compared with endoscopic balloon dilation and strictureplasty. Nevertheless, surgical resection is associated with more adverse events., (© The Author(s) 2024. Published by Oxford University Press on behalf of Crohn’s & Colitis Foundation. All rights reserved.

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]

Aim: The present study was performed on patients with large bile duct stones to compare clinical outcomes and complications of balloon dilatation treatment between two sizes of balloons, < 15 mm and ≥ 15 mm. Background: in 1982, the endoscopic papillary balloon dilatation (EPBD) method was presented by Staritz to reduce bleeding and perforation risk of large bile duct stones. Methods: Patients with large bile duct stones admitted to Taleghani hospital from December 2018 to December 2019 who were the candidates for balloon dilation with limited sphincterotomy. Patients were randomly divided into two groups. In group B, a ≥ 15 mm balloon was used, and in group A, a balloon <15 mm was used. The clinical results of balloon dilation and its complications were recorded and compared. Results: Most patients had 1 or 2 large bile duct stones, and there was no significant difference in the number of stones. Extraction was successful in 92.8% of group B and 85.7% of group A without significant differences (P = 0.8). Pancreatitis, hemorrhage, cholangitis, and perfusion occurred in 8%, 4.2%, 1.4%, and 2.8% of group B subjects and also in 10%, 2.8%, 0%, and 1.4% of group A subjects, respectively, and the difference between the two groups was not significant. Conclusion: Generally, this study results showed that balloon size did not have a significant effect on the success rate of bile duct stones. Moreover, considering the lack of significant association between balloon dilatation size and the occurrence of post-endoscopic complications such as pancreatitis, it seems that large-size dilatation has no serious clinical risk.

Endoscopic submucosal dissection (ESD) for extensive esophageal cancer is sometimes associated with post-ESD stenosis, despite preventative steroid therapy. In this retrospective multicenter analysis, we evaluated the factors associated with therapy resistance. We enrolled 73 patients with 75 extensive esophageal cancers treated with ESD. Stenosis prevention was performed using two esophageal triamcinolone acetonide (TA)-fillings, and repeated if stenosis was found on follow-up. Therapy-resistance factors associated with incidence of severe stenosis requiring endoscopic balloon dilation (EBD) were evaluated, including age, gender, previous treatment history, tumor location, morphology, resection size, histologic type, invasion depth, and horizontal resection grade (HR-grade 1, ≥ 9/12 and <10/12 of the circumference; grade 2, ≥ 10/12 and <11/12; grade 3, ≥ 11/12 but not circumferential; and grade 4, entirely circumferential). Severe stenosis occurred in 17.3%(13/75) of cases, with a median of two EBDs (range, 1–6 times). Severe stenosis was significantly associated with HR-grade elevation and previous treatment history (p <.05); multivariate analysis showed both as independent therapy-resistance factors (p <.05). Patients without previous treatment history demonstrated severe stenosis at 12.9%(9/70): 0%(0/26) HR-grade 1, 18.8%(3/16) grade 2, 17.6%(3/17) grade 3, and 27.3%(3/11) grade 4, showing a risk of HR-grade 2 or more resection but an acceptable stenosis prevention even after entirely circumferential resection. Conversely, patients with previous treatment history demonstrated severe stenosis at a high frequency of 80%(4/5). Esophageal TA-filling is a promising stenosis-preventive steroid therapy, even in entirely circumferential ESD cases. However, HR-grade 2 or more elevation and previous treatment history were independently associated with therapy resistance. [ABSTRACT FROM AUTHOR]

Introduction: Fibrostenosis is a hallmark of Crohn's disease (CD), remains a challenge in today's clinical management of inflammatory bowel disease patients and represents a key event in the disease course necessitating improved preventative strategies and a multidisciplinary approach to diagnosis and management. With the advent of anti-fibrotic therapies and well-defined clinical endpoints for stricturing CD, there is promise to impact the natural history of disease. Areas covered: This review summarizes current evidence in the natural history of stricturing Crohn's disease, discusses management approaches as well as future perspectives on intestinal fibrosis. Expert opinion: Currently, there are no specific therapies to prevent progression to fibrosis or to treat it after it becomes clinically apparent. In addition to the international effort by the Stenosis Therapy and Anti-Fibrotic Research (STAR) consortium to standardize definitions and propose endpoints in the management of stricturing CD, further research to improve our understanding of mechanisms of intestinal fibrosis will help pave the way for the development of future anti-fibrotic therapies.

Stricture formation is common in Crohn's disease, and endoscopic intervention plays an increasingly important role in managing these strictures. A 61-year-old man with biological aortic prosthesis and a 30-year history of ileocolonic stricturing Crohn's disease, managed with azathioprine and infliximab, presented with marked occlusive symptoms. Colonoscopy revealed a descending colon stricture, prompting endoscopic balloon dilation. At the time of the procedure, no prophylactic antibiotic was given. Subsequently, he developed Streptococcus gallolyticus endocarditis, necessitating aortic valve replacement. The authors present a case of late Streptococcus gallolyticus endocarditis associated with endoscopic balloon dilation of a Crohn-related colonic stricture., (© 2024 The Author(s).

Esophageal perforation is a rare but critical emergency that requires early detection and prompt management. In the pediatric population, iatrogenic injury is the most common etiology of esophageal perforation, and the majority of cases come from stricture dilation. Treatment options include medical management, endoscopic therapy, and surgery. Usually, conservative treatment is appropriate in most carefully selected patients, especially in the setting of early diagnosis and with the absence of severe sepsis. A surgical approach is reserved for a large tear with mediastinum contamination, or clinical deterioration after unsuccessful conservative management. With the advancement of the endoscopy technique, endoscopy therapy using esophageal stents is an available choice for adult populations who have a complicated protracted healing course or comorbidities precluding surgical attempts. However, this procedure is seldom implemented in children, especially in young infants, owing to unavailable equipment and experts. We report our successful use of a fully-covered self-expandable metal biliary stent in managing esophageal perforation in a seven-month-old infant. In light of this encouraging achievement, this model can be applied to more children who have the same problem.

Background: There is no information regarding the outcome of Crohn's disease (CD) patients treated with endoscopic balloon dilation (EBD) in non-referral hospitals, nor on the efficacy of EBD in ulcerative colitis (UC). We report herein the results of the largest series published to date.Aim: To assess the efficacy and safety of EBD for inflammatory bowel disease (IBD) stenosis performed in 19 hospitals with different levels of complexity and to determine factors related to therapeutic success.Methods: We identified IBD patients undergoing EBD in the ENEIDA database. Efficacy of EBD was compared between CD and UC and between secondary and tertiary hospitals. Predictive factors of therapeutic success were assessed with multivariate analysis.Results: Four-hundred dilations (41.2% anastomotic) were performed in 187 IBD patients (13 UC/Indeterminate colitis). Technical and therapeutic success per dilation was achieved in 79.5% and 55.3%, respectively. Therapeutic success per patient was achieved in 78.1% of cases (median follow-up: 40 months) with 49.7% requiring more than one dilation. No differences related to either diagnosis or hospital complexity was found. Technical success [OR 4.12 (95%CI 2.4-7.1)] and not receiving anti-TNF at the time of dilation [OR 1.7 (95% CI 1.1-2.6)] were independently related to therapeutic success per dilation. A stricture length ≤ 2 cm [HR 2.43 (95% CI 1.11-5.31)] was a predictive factor of long-term success per patient. The rate of major complications was 1.3%.Conclusions: EBD can be performed with similar efficacy and safety in hospitals with differing levels of complexity and it might be a suitable treatment for UC with short stenosis. To achieve a technical success and the short length of the stenosis seem to be critical for long-term therapeutic success. [ABSTRACT FROM AUTHOR]

The therapeutic target in Crohn's disease (CD) has been raised to the achievement of mucosal healing. Although effective treatments that target cytokines and other molecules has been widely used for CD, intestinal strictures are still a major cause of surgery. Endoscopic balloon dilation (EBD) is known to be an effective and safe intervention for intestinal strictures in CD. Since frequent intestinal resection often results in short bowel syndrome and can decrease the quality of life, EBD can help avoid surgery. EBD with a conventional colonoscope for Crohn's strictures of the colon and ileo-colonic anastomosis has established efficacy and safety. In addition, EBD using balloon-assisted enteroscopy has recently been applied for small bowel Crohn's strictures. Although the evidence is not strong, EBD may become an alternative to surgery in small bowel strictures in CD. EBD and other new methods such as self-expanding stent implantation for Crohn's strictures may be useful and safe; however, it is important to address several issues regarding these interventions and to establish a protocol for combined therapies.
