Management of Zenker's diverticulum using flexible endoscopy.

ABSTRACT: Background and Aims:Zenker's diverticulum is a false diverticulum through Killian's dehiscence. Symptoms include halitosis, dysphagia, regurgitation, cough, and aspiration pneumonia. Treatment options include open transcervical cricopharyngeal myotomy, trans-oral rigid endoscopic stapling, and minimally invasive endoscopic myotomy. Although open surgical techniques have historically been the criterion standard for treatment, endoscopic options have become increasingly used. We propose the use of flexible endoscopy in the management of Zenker's diverticulum. Methods:We present a retrospective case series of 9 patients undergoing endoscopic cricopharyngeal myotomy from 2014 to 2018 using our endoscopic technique. Results:We demonstrate that endoscopic technique provided adequate symptomatic relief in 7 of 9 patients, with no operative adverse events. Conclusions:Cricopharyngeal myotomy using flexible endoscopy is a safe and effective technique for the management of Zenker's diverticulum. Potential benefits of this approach include shorter operative times, shorter postoperative admissions, and earlier progression of diet. Initial treatment with endoscopic technique does not preclude future open repairs.

Project description:To assess the placement, surveillance management and long-term outcomes of the tracheobronchial (TB) balloon expandable metallic stent (BEMS) managed by therapeutic flexible endoscopy (TFE).This is a retrospective review and analysis of all computerized medical records and related flexible endoscopy videos of pediatric patients who received TB BEMS during 20 years period, from January 1997 to December 2016. TFE techniques with forceps debridement, balloon dilatation and laser ablation were used to implant stents, perform regular surveillance, maintain their functions, and expand the diameters of BEMS. Short-length (30cm-36cm) endoscopes of OD 3.2mm to 5.0mm coupled with the noninvasive ventilation, without ventilation bag, mask or airway tube, supported the whole procedures.146 BEMS were implanted in 87 consecutive children, including 84 tracheal, 15 carinal and 47 bronchial stents. At the time of placement, the mean age was 35.6 ± 54.6 month-old (range 0.3-228) and the mean body weight was 13.9 ± 10.6 kg (range 2.2-60). Surveillance period was 9.4 ± 6.7 years (range, 0.3-18.0). Satisfactory clinical improvements were noted immediately in all but two patients. Seventy-two (82.8%) patients were still alive with stable respiratory status, except two patients necessitating TFE management every two months. Fifty-one stents, including 35 tracheal and 16 bronchial ones, were successfully retrieved mainly with rigid endoscopy. Implanted stents could be significantly (< .001) further expanded for growing TB lumens. The final stent diameters were positively correlated to the implanted duration. Altogether, 33 stents expired (15 patients), 51 were retrieved (40 patients), and 62 remained and functioning well (38 patients), with their mean duration of 7.4 ± 9.5, 34.9 ± 36.3 and 82.3 ± 62.5 months, respectively.In pediatric patients, TFE with short-length scopes coupled with this NIV support has provided a safe, feasible and effective modality in placing and subsequently managing TB BEMS with acceptable long-term outcomes.
