Project description:BackgroundPeroral endoscopic myotomy (POEM) is an emerging technique in the treatment of Zenker's diverticulum (ZD). This study aimed to analyze the feasibility of Zenker's POEM (Z-POEM) in a multicenter setting and assess its performance using a validated Kothari-Haber Scoring System newly developed for symptom measurement in ZD.Materials and methodsThis was a multicenter retrospective study involving three Polish tertiary referral endoscopic units. The data of consecutive patients with symptomatic ZD treated with Z-POEM in Poland between May 2019 and August 2020 were retrieved and analyzed. Primary outcome measures were technical success and clinical success rate (<3 points in Kothari-Haber Score at 2-3 months follow-up). Secondary outcome measures included procedures' duration, length of hospital stay, and adverse events.Results22 patients with symptomatic ZD were included. The mean age was 67.6 (±10.7) years, and 14 (63.6%) were male. All but two patients were treatment naïve. The average size of the ZD was 30 mm (IQR, 24-40 mm). Technical success was achieved in all patients (100%), whereas clinical success was 90.9%. The average Kothari-Haber Score was 6.35 before treatment and has dropped to 0.65 after the treatment (p < 0.0001). The mean procedure time was 48.8 (±19.3) minutes, and the median length of hospital stay was 2 days (IQR, 2-3). Three patients (13.6%) had post-procedural emphysema, of which two were mild and self-resolving (9.1%), and one was moderate (4.5%) and complicated with laryngeal edema and prolonged intubation.ConclusionsThis feasibility study suggests that Z-POEM is a highly effective and safe treatment for ZD, particularly among treatment-naïve patients. Comparative studies with other treatment modalities over longer follow-up are warranted.

Project description:Background and aimsZenker's diverticulum (ZD) is attributed to a poorly compliant cricopharyngeus muscle, and the mainstay of treatment is a cricopharyngeal myotomy. We present a video series summarizing endoscopic treatment options for ZD and related conditions.MethodsWe review the rationale and key technique for various endoscopic treatment modalities for ZD, cricopharyngeal bar, and other esophageal diverticula.ResultsStandard flexible endoscopic cricopharyngeal myotomy involves the division of the common wall or septum of the ZD, aiming for complete transection of the cricopharyngeus. However, recurrence rates are high, likely owing to incomplete myotomy. Zenker's peroral endoscopic myotomy (Z-POEM) uses a proximal submucosal tunnel to provide direct visualization of the cricopharyngeus and septum, allowing confirmation of complete myotomy. We demonstrate an over-the-septum modification to simplify the technique. Submucosal fibrosis, commonly seen in patients with prior treatment, limits submucosal dissection. We present a hybrid technique to overcome this, whereby a traditional septotomy is performed until submucosal tissue is visualized. The intact mucosal flap after Z-POEM in a large ZD may contribute to residual dysphagia. We propose Z-POEM with mucosotomy for large ZD. Finally, we demonstrate modifications for treatment of other esophageal diseases, including cricopharyngeal bar and non-Zenker's esophageal diverticula.ConclusionEndoscopic treatment options for ZD and related conditions are rapidly expanding. With careful tailoring to individual patient characteristics, our expanding arsenal of options allows effective and safe treatment of a broad spectrum of patients.

Project description:Background and aimsZenker'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.MethodsWe present a retrospective case series of 9 patients undergoing endoscopic cricopharyngeal myotomy from 2014 to 2018 using our endoscopic technique.ResultsWe demonstrate that endoscopic technique provided adequate symptomatic relief in 7 of 9 patients, with no operative adverse events.ConclusionsCricopharyngeal 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:We discuss an unusual presentation of Zenker's Diverticulum (ZD). A 76-year-old man presented with a left sided neck mass which was misdiagnosed as a thyroid mass due to the anatomical location and size. The ultrasound and fine needle-aspiration cytology findings were inconclusive, and a CT scan was then considered which reported a large pharyngeal pouch. Our recommendation is to consider an early CT scan in patient's where there is a clinical suspicion or risk factors for the development of pharyngeal pouch specially when the fine-needle aspiration cytology findings are inconclusive. This would reduce the risk of a delayed diagnosis which can prevent potential perforation of the pharyngeal pouch and development of mediastinitis.

Project description:BackgroundIn recent years, flexible endoscopic therapy of Zenker's diverticulum seems to become the standard approach. The aim of this study was to assess the safety, efficacy and short-term outcome of flexible endoscopic diverticulotomy of Zenker's diverticulum with a pulsed Holmium laser (PHL).Patients and methodsAll patients treated with endoscopic laser-diverticulotomy using a PHL between February 2013 and November 2021 at the University Hospital Salzburg were extracted from our prospectively maintained endoscopic database. Demographic data, size of Zenker's diverticulum, procedure duration, complications, short-term outcome and rate of recurrence were evaluated.ResultsIn the study period, 45 procedures in 36 patients were performed. Mean depth of the Zenker diverticulum was 21 mm (10-60 mm), mean procedure time was 31 min (15-60 min), intraprocedural adverse events occurred in 2 out of 45 patients (5%) which were both managed endoscopically, post-procedural stenosis occurred in 1 patient (2%). In the follow-up examinations (mean follow-up after 6.4 months), 27 out of 36 patients (75%) were symptom-free, 6 patients (17%) reported an improvement of dysphagia. 3 patients (9%) suffered from persistent dysphagia. After initial symptom relief, a recurrent diverticulum occurred in 5 patients. Endoscopic re-intervention with PHL was done in these cases.ConclusionsFlexible endoscopic treatment of primary and recurrent Zenker's diverticulum using a PHL is a promising, safe and effective treatment with, in our opinion, technical advantages in comparison to the CO2 laser. Further controlled prospective trials are needed.
