Purpose: To prospectively evaluate the midterm outcomes of fluoroscopic eustachian tube (E-tube) balloon dilation by using a flexible guide wire in patients with obstructive E-tube dysfunction.
Materials And Methods: From October 2016 to September 2017, adult outpatients with persistent otitis media who were unable to perform the Valsalva maneuver were prospectively enrolled. The analysis included 32 E-tubes from 31 patients (18 women, 13 men; mean age, 47 years old, range 25-72 years). Participants underwent fluoroscopic E-tube balloon dilation with a 0.035-inch flexible guide wire and a 6- × 20-mm balloon catheter. Clinical examinations to check for the ability to perform the Valsalva maneuver and otomicroscopy were conducted at 1 week and then at 1, 3, 12, and 18 months after the procedure.
Results: Balloon dilation was technically successful in all E-tubes. The mean time required for the procedure was 6.9 minutes (range, 5.8-10.3 minutes). The Valsalva maneuver was successful in opening 25 of 32 E-tubes (78.1%) at 3 months after balloon dilation. During the median follow-up of 15.9 months, failure of the Valsalva maneuver occurred in 4 of 25 improved E-tubes (16%), yielding a 2-year patency rate of 84%.
Conclusions: The fluoroscopic balloon dilation results were encouraging, and using a flexible guide wire for E-tube balloon dilation did not cause a false passage.

Efficacy of robot-assisted double-flap techniques with refinements to minimize anastomosis-related complications after proximal gastrectomy.

Purpose: The double-flap technique (DFT) is an anti-reflux reconstruction procedure performed after proximal gastrectomy (PG), but its complexity and high incidence of anastomotic stenosis are problematic. We conducted this study to demonstrate the efficacy of robot-assisted DFT, with refinements, to address these issues.
Methods: Surgical outcomes were compared between the following procedures modified over time at our institution: conventional open DFT (group O, n = 16); early robotic DFT (group RE, n = 19), which follows the conventional open PG approach; and late robotic DFT (group RL, n = 21), which incorporates refinements to the early robotic DFT technique by exploiting more of the robotic capabilities available.

Contemporary Use of Post-Dilatation for Stent Optimization During Percutaneous Coronary Intervention; Results From the Netherlands Heart Registration.

Heart Centre, Catharina Hospital, Eindhoven, The Netherlands.
Backgrounds: Post-dilatation after stenting with a non-compliant (NC) balloon can be used to improve overall percutaneous coronary intervention (PCI) result. Due to lack of evidence on the effect of post-dilatation on adverse clinical endpoints there is no consensus whether post-dilatation should be used routinely. The aim of the current study was to determine the contemporary practice of post-dilatation.

Objective: This study aims to evaluate the clinical utility and effectiveness of a nomogram model in predicting outcomes for patients with benign esophagogastric anastomotic stenosis (BES) undergoing fluoroscopic balloon dilation (FBD).
Methods: The clinical data of 428 patients with BES who received FBD treatment at our hospital between January 2013 and June 2023 were retrospectively analyzed. The patients were divided into training and validation cohorts in a 7:3 ratio.
