Two-Stage Peroral Endoscopic Myotomy for Sigmoid-Type Achalasia.

Project description:Peroral endoscopic myotomy (POEM) has been recently considered as the first treatment option for achalasia. The standard POEM procedures are often successful in most patients, but sometimes technical challenges are encountered. We report a new technique that is divided between two tunneling sites in the esophagus for sigmoid-type achalasia. A 40-year-old male patient with dysphagia for 10 years was diagnosed with a sigmoid-shaped esophagus at our hospital. We devised a two-stage myotomy technique to treat sigmoidtype achalasia. The myotomy was first performed in the upper part of the greater flexion area and then in the lower part of the flexion. We termed this method "two-stage POEM", which was successfully performed without any complications. This new POEM method can also be used to improve symptoms in patients with achalasia who have a structural deformity that may result in a high change of treatment failure.

Peroral Endoscopic Myotomy for the Treatment of Achalasia in a 10-Year-Old Male Patient.

Project description:Peroral endoscopic myotomy (POEM) is a new endoscopic treatment for achalasia with very good short-term results in adults. Data about POEM in pediatric patients are missing. We present the case of a 10-year-old male patient with type I (classic) achalasia, successfully treated with POEM. The procedure was accomplished in a similar fashion to the technique used in adults. Short-term results were fine, with a complete control of dysphagia and absence of reflux. We suggest that POEM is a suitable option in pediatric patients-similar to adults-but long-term results must be awaited.

Esophageal Motility Patterns After Peroral Endoscopic Myotomy in Patients With Achalasia.

Project description:Background/aimsSeveral studies have reported partial recovery of peristalsis in patients with achalasia after myotomy. The aim of our study is to analyze esophageal motility patterns after peroral endoscopic myotomy (POEM) and to assess the potential predictors and clinical impact of peristaltic recovery.MethodsWe performed a retrospective analysis of prospectively collected data of consecutive patients with achalasia undergoing POEM at a tertiary center. High-resolution manometry (HRM) studies prior to and after POEM were reviewed and the Chicago classification was applied.ResultsA total of 237 patients were analyzed. The initial HRM diagnoses were achalasia type I, 42 (17.7%); type II, 173 (73.0%); and type III, 22 (9.3%). Before POEM, peristaltic fragments were present in 23 (9.7%) patients. After POEM the Chicago classification diagnoses were: 112 absent contractility, 42 type I achalasia, 15 type II, 11 type III, 26 ineffective esophageal motility, 18 esophagogastric junction outflow obstruction, 10 fragmented peristalsis, and 3 distal esophageal spasm. Altogether 68 patients (28.7%) had signs of contractile activity, but the contractions newly appeared in 47 patients (47/214, 22.0%). Type II achalasia showed a trend for appearance of contractions (P = 0.097). Logistic regression analysis did not identify any predictors of peristaltic recovery. The post-POEM Eckardt score did not differ between patients with and without contractions nor did the parameters of timed barium esophagogram.ConclusionsMore than 20% of achalasia patients have signs of partial recovery of esophageal peristalsis after POEM. It occurs predominantly in type II achalasia but the clinical relevance seems to be negligible.

Peroral Endoscopic Myotomy in the Management of Zenker's Diverticulum: A Retrospective Multicenter Study.

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.

Abnormal performance of peroral endoscopic myotomy (POEM): a case misdiagnosed as achalasia of cardia.

Project description:BackgroundPseudoachalasia is a rare disease that behaves similarly to achalasia (AC), making it sometimes difficult to differentiate.Case presentationWe report a case of 49-year-old male with adenocarcinoma of the gastroesophageal junction misdiagnosed as achalasia. No obvious abnormalities were found in his initial examinations including upper digestive endoscopy, upper gastrointestinal imaging and chest computed tomography (CT). During the subsequent introduced-peroral endoscopic myotomy (POEM), it was found that the mucosal layer and the muscular layer had severe adhesion, which did not receive much attention, delayed the clear diagnosis and effect treatment, and ultimately led to a poor prognosis for the patient.ConclusionsThis case suggests that when patients with AC found mucosal and muscular adhesions during POEM surgery, the possibility should be considered that the lesion may be caused by a malignant lesion.
