Review of(acquired) incidental, rare and difficult tracheoesophageal fistula management

引用

World Journal of Surgical Procedures 2014年第1期4卷 9-12页

作者： Jose Paulo Freire Jose Crespo Mendes de Almeida Department of General Surgery Hospital de Santa Maria 1649-035 Lisbon Portugal

Acquired benign tracheoesophageal fistula is a rare condition and a difficult problem. The rarity and unpredictable presentation of this condition makes the design and setting of randomized prospective trials impossible. Guidelines on this matter are also difficult to establish. Based on a comprehensive evaluation of published literature and their experience, the authors review the etiology and best options for treatment, either surgical and non surgical, according to present knowledge.

One Stage Reconstruction of Esophageal Atresia and Distal tracheoesophageal Fistula in a 3250-gm Neonate: A Case Report

引用

Open Journal of Pediatrics 2015年第2期5卷 147-150页

作者： Bijay Upadhyay Xuedong Wu Jun Li Ning Wang Shanshan Zhang Na Li Department of Pediatric Surgery Affiliated Hospital of Dali University Dali China

Esophageal atresia (EA) occurs when the upper part of the esophagus does not connect with the lower part of esophagus and stomach. tracheoesophageal fistula (TEF) is an abnormal connection between the upper part of the esophagus and the trachea. Treatment for esophageal atresia has advanced over several decades due to improvements in surgical techniques and neonatal intensive care. The aim is to share our experience regarding the treatment of esophageal atresia with tracheoesophageal fistula. A 4-day-old neonate suffering from esophageal atresia with type IIIB tracheoesophageal fistula underwent one stage esophageal reconstruction and obtained good outcome without any complications. In this paper, a simple intra-operative technique for tracheal fistula repair and end to end esophageal anastomosis is discussed. We used a simple technique that we have found useful for ligation of tracheal fistula. Anastomosis of lower and upper esophagus without any complication like anastomotic leakage or stricture/stenosis of the neonate with EA/TEF (type IIIB), was proved to be safe and effective.

Endoscopic management for congenital esophageal stenosis: A systematic review

引用

World Journal of Gastrointestinal Endoscopy 2015年第3期7卷 183-191页

作者： Keita Terui Takeshi Saito Tetsuya Mitsunaga Mitsuyuki Nakata Hideo Yoshida Department of Pediatric Surgery Graduate School of Medicine Chiba University

Congenital esophageal stenosis(CES) is an extremely rare malformation, and standard treatment have not been completely established. By years of clinical research, evidence has been accumulated. We conducted systematic review to assess outcomes of the treatment for CES, especially the role of endoscopic modalities. A total of 144 literatures were screened and reviewed. CES was categorized in fibromuscularthickening, tracheobronchial remnants(TBR) and membranous web, and the frequency was 54%, 30% and 16%, respectively. Therapeutic option includes surgery and dilatation, and surgery tends to be reserved for ineffective dilatation. An essential point is that dilatation for TBR type of CES has low success rate and high rate of perforation. TBR can be distinguished by using endoscopic ultrasonography(EUS). Overall success rate of dilatation for CES with or without case selection by using EUS was 90% and 29%, respectively. Overall rate of perforation with or without case selection was 7% and 24%, respectively. By case selection using EUS, high success rate with low rate of perforation could be achieved. In conclusion, endoscopic dilatation has been established as a primary therapy for CES except TBR type. Repetitive dilatation with gradual step-up might be one of safe ways to minimize the risk of perforation.
