Background: The esophageal stricture is an important clinical problem in children, and the treatment is difficult.
Objective: To evaluate the results of fluoroscopy-guided balloon dilatation of benign pediatric esophageal strictures and to suggest a safety range for balloon diameters.
Materials And Methods: We retrospectively reviewed the medical records of children who underwent fluoroscopy-guided esophageal balloon dilatation for treatment of benign esophageal stricture from February 2008 to July 2019. We recorded the demographic data of the children, technical details of each procedure, balloon diameter, number of repeated procedures, clinical and technical success rates, complications and follow-up period. Technical success was defined as the disappearance of the waist formation on the balloon catheter, and clinical success was defined as no need for re-dilation or other treatment methods during the 1-year follow-up after the procedure. These children were divided into groups and evaluated according to esophageal stricture etiology.
Results: Technically successful procedures included 375 balloon dilatations in 116 patients (67 boys; age range: 1 month to 18 years; mean age: 4.3 ± 4.8 standard deviation [SD] years at the initial dilatation). The follow-up period was 1-138 months (median: 41 months; mean: 44 months) since the last dilatation. In this study, the clinical success rate was 34% per procedure (120 of 353 procedures) and 85% per patients (91 of 107 patients). The total complication rate per procedure was 0.5%, and the perforation rate was 0.25% per session.
Conclusion: Fluoroscopy-guided esophageal balloon dilatation is an effective and reliable method for treating benign esophageal strictures in children.

The management of locally advanced esophageal cancer typically involves esophagectomy; however, postoperative complications, particularly anastomotic stricture, remain prevalent. Anastomotic stricture can severely compromise patients' quality of life by leading to difficulties in food intake. Although endoscopic balloon dilation has become a standard treatment for gastrointestinal strictures, its efficacy is often limited due to the risk of perforation and the potential for recurrent stricture, necessitating multiple interventions.

Background: Coarctation of the aorta (CoA) is a narrowing of the aorta that affects 5-8% of congenital heart defects. Treatment options include surgical repair or transcatheter management with endovascular stenting or balloon dilatation. Late complications after operative repair include systemic hypertension, aortic valve abnormalities, aortic aneurysm, and recoarctation.

Background: In patients with mechanical aortic and mitral valves requiring catheter ablation of ventricular tachycardia (VT), a technique for access from the right atrium (RA) to the left ventricle (LV) via puncture of the inferoseptal process of the LV was previously described in a single-center series.
Objectives: This study sought to report the multicenter experience of VT ablation using this novel LV access approach.
Methods: We assembled a multicenter registry of patients with double mechanical valves who underwent VT ablation with RA-to-LV access.
Cervical balloon catheter versus Dilapan-S for outpatient cervical ripening: A randomized controlled trial.

Division of Maternal Fetal Medicine, Brigham and Women's Hospital.
Background: As induction of labor increases in the United States, safe, effective outpatient cervical ripening has been explored as a method to decrease the inpatient time burden. The most effective method of outpatient mechanical cervical ripening remains unclear.
Objective: To evaluate if Dilapan-S is non-inferior to cervical balloon for outpatient cervical ripening (CR) based on change in Bishop score.
Background: Predicting successful outcomes of gastric peroral endoscopic myotomy (G-POEM) is essential for identifying patients who are most likely to benefit from the procedure. This study aimed to evaluate the utility of the balloon dilation test (BDT) in optimizing patient selection for G-POEM.
Methods: A retrospective study was conducted from February 2021 to December 2023, including patients with refractory gastroparesis unresponsive to conventional medical treatments.
