Objective: An infant born with long-gap esophageal atresia has its esophagus separated into two pouches, and typically undergoes multiple open-chest surgeries for esophageal reconstruction. In this paper, we study a possible approach for less invasive correction of long-gap esophageal atresia.
Methods: Our technique utilizes a magnet-tipped catheter with a piston on the end to push the esophageal pouch from the inside. The attractive magnetic force helps the catheter stretch the esophageal pouches, while the hydraulic piston prevents the magnet from applying too large force. The piston also enables estimation of the esophageal tension based on the hydraulic pressure measurement.
Results: We have built a prototype system and performed bench-level tests on an esophageal mock-up. A hydraulic dither is applied to the piston to average out seal friction, thereby improving the tension estimation performance.
Conclusion: The bench-level tests demonstrate that the prototype bougienage system gives a reliable low-frequency estimate of the esophageal tension in real-time, and also enables longitudinal bougienage by a desired amount of load, e.g., 2N, for various gap sizes.
Significance: This study provides a foundation for the next step of designing a system for use on actual patients.

Thoracoscopic Repair of Long-Gap Esophageal Atresia Using the Thoracoscopic Internal Traction Technique: A Challenging Feat.

Long-gap esophageal atresia (LGEA) is an abnormality in the development of the esophagus resulting in the disruption of the continuity of the esophageal lumen with no feasible primary repair due to the "long gap" between two esophageal stumps. There is controversy regarding both the precise definition and the treatment protocol of this congenital condition. Methods such as delayed primary repair, open external traction, thoracoscopic external traction, and thoracoscopic internal traction were used in the treatment of patients with varied outcomes.

Aim: This study aims to explore the rationality, feasibility, safety, and effectiveness of single-incision laparoscopic gastric pull-up (SILS-GPU) and robot-assisted gastric pull-up (R-GPU) methods.
Methods: Hospital records of patients who underwent gastric pull-up with either SILS-GPU or R-GPU between May2016 and January 2024 were reviewed. Demographics, diagnosis, surgical techniques, and postoperative outcomes were evaluated.

Background: Children undergoing surgical anastomosis for long-gap esophageal atresia (LGEA) often suffer from complications related to delayed oral feeding, which may impair their early development. Clinical swallow evaluation (CSE) is an effective technique to improve feeding outcomes. However, there are limited evidences on the application of CSE in these children.

Purpose: We sought to engage with expert patient/carers to understand attitudes towards use of tissue engineering (TE) for long-gap oesophageal atresia (OA).
Methods: An in-person engagement event for 70 patients/parents was held by the OA patient group, TOFS. Attitudes towards TE were assessed before and after a talk on use of TE oesophagi in a pre-clinical OA model.

Objectives: Survival rates in children born with esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) have improved; however, morbidity associated with the disease remains high. This study aimed to assess the prevalence of gastroesophageal reflux disease (GERD), eosinophilic esophagitis (EoE), fungal esophagitis, esophageal strictures, and long-term outcomes in children with EA/TEF.
Methods: We conducted a retrospective chart review on patients with EA/TEF who were seen at Children's Wisconsin from January 2003 to January 2023.
