Peroral endoscopic myotomy (POEM) is an excellent endoscopic treatment for achalasia. Clinical and manometric parameters are used for evaluation and follow-up. However, clinical success does not guarantee high quality of life (QoL) scores, generating doubts about their direct relationship. We aimed to evaluate QoL scores before and after POEM at medium and long term, to evaluate differences between achalasia subtypes and find which factors related to low QoL scores. Achalasia-confirmed patients undergoing POEM between February 2012 and November 2016. and completing at least 1 year of follow-up, were included. Assessment before and at 1, 6, 12, 24, 36 and 48 months after POEM employed manometry, barium series, Eckardt score, and the AE-18 health-related QoL scale. Demographic, clinical, and procedure characteristics were documented, with comparisons between subgroups. Multiple logistic regression analysis was done. 65 of 88 patients were included (38 women, 27 men; median age 47 years, interquartile range [IQR] 20 - 81), and 50 (76.9 %) completed 4 years of follow-up. Eckardt score improved (median, preprocedure 10 vs. post-procedure 2; = 0.002) and this persisted. There was initial improvement in median integrated relaxation pressure (IRP) (29.4 mmHg [16 - 55] vs. 10.3 mmHg [3 - 18]; = 0.000) and median QoL scores (40 vs. 68 at 1 month; = 0.002); however IRP increased and QoL scores decreased. Men with confirmed type III achalasia had low QoL scores. All patients had significant clinical improvement after POEM, with medium- to long-term persistence. Though quality of life and IRP initially improved, they deteriorated in the long term. Male sex and type III achalasia seem to be associated with low QoL scores.
Background Treatment of Zenker’s diverticulum has evolved from open surgery to endoscopic techniques, including flexible and rigid endoscopic septotomy, and more recently, peroral endoscopic myotomy (Z-POEM). This study compared the effectiveness of flexible and rigid endoscopic septotomy with that of Z-POEM.
Methods Consecutive patients who underwent endoscopic septotomy (flexible/rigid) or Z-POEM for Zenker’s diverticulum between 1/2016 and 9/2019 were included. Primary outcomes were clinical success (decrease in Dakkak and Bennett dysphagia score to ≤ 1), clinical failure, and clinical recurrence. Secondary outcomes included technical success and rate/severity of adverse events.
Results 245 patients (110 females, mean age 72.63 years, standard deviation [SD] 12.37 years) from 12 centers were included. Z-POEM was the most common management modality (n = 119), followed by flexible (n = 86) and rigid (n = 40) endoscopic septotomy. Clinical success was 92.7 % for Z-POEM, 89.2 % for rigid septotomy, and 86.7 % for flexible septotomy (P = 0.26). Symptoms recurred in 24 patients (15 Z-POEM during a mean follow-up of 282.04 [SD 300.48] days, 6 flexible, 3 rigid [P = 0.47]). Adverse events occurred in 30.0 % rigid septotomy patients, 16.8 % Z-POEM patients, and 2.3 % flexible septotomy patients (P < 0.05).
Conclusions There was no difference in outcomes between the three treatment approaches for symptomatic Zenker’s diverticulum. Rigid endoscopic septotomy was associated with the highest rate of complications, while flexible endoscopic septotomy appeared to be the safest. Recurrence following Z-POEM was similar to flexible and rigid endoscopic septotomy. Prospective studies with long-term follow-up are required.
Background Zenker’s peroral endoscopic myotomy (Z-POEM) is a novel procedure for the management of symptomatic Zenker’s diverticulum. This study aims to report the technical feasibility and outcomes of Z-POEM in the management of Zenker’s diverticulum after prior failed interventions.
Methods Patients with persistent or recurrent symptoms after prior endoscopic and/or surgical intervention for Zenker’s diverticulum were retrospectively included. The primary outcome was clinical success, defined as complete or near complete resolution of dysphagia (dysphagia score of 0 or 1) without the need for repeat endoscopic or surgical intervention during follow-up.
Results Z-POEM was technically successful in 30/32 patients (93.8 %). Clinical success was achieved in 29/30 patients (96.7 %), and Z-POEM significantly reduced the median (interquartile range [IQR]) dysphagia score of patients from 2 (1 – 2) to 0 (0) (P < 0.001) over a median duration of follow up of 166 days (IQR 39 – 566). Four patients (12.5 %) had adverse events (two inadvertent mucosotomies and two leaks found on post-procedural esophagrams).
Conclusion Z-POEM is feasible, safe, and effective in the majority of patients with recurrent symptoms after prior surgical or endoscopic interventions.
