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.
This surgical procedure is a first line in the treatment of esophageal achalasia. It is necessary to have special care in early diagnostic cases to avoid electrosurgical injury.
Background Peroral endoscopic myotomy (POEM) is a recognized technique for patients with achalasia. We aimed to evaluate the feasibility of using a small-caliber endoscope (thin-POEM) to perform POEM in patients with achalasia.
Methods Naïve or previously treated patients were included between February 2016 and April 2018. A small-caliber (5.9 mm) nasoendoscope was used, with a modified closure method using cyanoacrylate. Strict follow-up was performed.
Results 45 patients were included, aged 45.5 years (interquartile range [IQR] 22 – 69); 53 % (24/45) had type II achalasia. Median total time for thin-POEM was 54 minutes (IQR 37 – 77) and median myotomy length was 13.5 cm (IQR 6 – 20). Results pre-procedure and 3 months post were Eckardt score 10 vs. 1 (P < 0.001), integrated relaxation pressure (IRP) 25.3 vs. 8.5 mmHg (P < 0.001), and timed barium esophagram (TBE) 100 % severely delayed vs. 86 % normal (P < 0.001), respectively. Type III patients had the longest thin-POEM times (median 58 minutes [IQR 52 – 77]). Reflux was confirmed at 3 months clinically in 17 % of patients, endoscopically in 20 %, and on pH monitoring in 53 %. At 6 months and 12 months, 40 % and 33 % of patients remained positive on pH monitoring and were medically managed.
Conclusions Thin-POEM seems to be a safe, effective, and efficient procedure for POEM in patients with achalasia, with good short-term follow-up results.
