RESUMEN
BACKGROUND: Esophageal dysmotility is a common finding in patients being evaluated for antireflux surgery, although its implication remains unclear. We aimed to evaluate outcomes of patients with esophageal dysmotility after fundoplication. METHODS: A retrospective review of a prospective quality-database was performed. All patients who underwent laparoscopic Nissen (NF) or Toupet (TF) fundoplication were included. Esophageal dysmotility was defined using the Chicago Classification v4.0 and conventional metrics, creating three sub-groups: ineffective esophageal motility (IEM), distal/diffuse esophageal spasm (DES), and hypercontractile esophagus (HE). Quality of life (QOL) outcomes were measured by the Reflux Severity Index (RSI), Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL), and Dysphagia Scores. RESULTS: Of 487 patients included, 99 (20.3%) had esophageal dysmotility (49 IEM, 40 DES, 10 HE). While a majority in the dysmotility group (81.8%) underwent TF, most patients in the normal group (76.5%) underwent NF (p < 0.001). On multivariable analysis controlling for sex, age, BMI, hiatal hernia, and surgery type, the normal group had higher Dysphagia Scores at 3 weeks (2.2 ± 0.9 vs. 1.7 ± 0.8, p < 0.001), but not at 6-month, 1-year, 2-year, or 5-year follow-up. There were no differences between normal and dysmotility groups in terms of RSI or GERD-HRQL scores at any time point. Patients with different sub-types of esophageal dysmotility had similar QOL outcomes at all time points. CONCLUSION: Patients with esophageal dysmotility had similar outcomes compared to those with normal motility after fundoplication, suggesting the tailored approach favoring partial fundoplication for patients with dysmotility as part of an appropriate treatment algorithm.

BACKGROUND: There is growing interest in developing impedance planimetry as a tool to enhance the clinical outcomes for endoscopic and surgical management of achalasia. The primary aim of this study was to determine whether impedance planimetry measurements can predict clinical response and reflux following peroral endoscopic myotomy (POEM). METHODS: A multicenter cohort study of patients with achalasia undergoing POEM was established from prospective databases and retrospective chart reviews. Patients who underwent impedance planimetry before and after POEM were included. Clinical response was defined as an Eckardt score of ≤â3. Tenfold cross-validated area under curve (AUC) values were established for the different impedance planimetry measurements associated with clinical response and reflux development. RESULTS: Of the 290 patients included, 91.7â% (266/290) had a clinical response and 39.4â% (108/274) developed reflux following POEM. The most predictive impedance planimetry measurements for a clinical response were: percent change in cross-sectional area (%ΔCSA) and percent change in distensibility index (%ΔDI), with AUCs of 0.75 and 0.73, respectively. Optimal cutoff values for %ΔCSA and %ΔDI to determine a clinical response were a change of 360â% and 272â%, respectively. Impedance planimetry values were much poorer at predicting post-POEM reflux, with AUCs ranging from 0.40 to 0.62. CONCLUSION: Percent change in CSA and distensibility index were the most predictive measures of a clinical response, with a moderate predictive ability. Impedance planimetry values for predicting reflux following POEM showed weak predictive capacity.

BACKGROUND AND STUDY AIMS: The efficacy of per oral endoscopic myotomy (POEM) in non-achalasia esophageal motility disorders such as esophagogastric junction outflow obstruction (EGJOO), diffuse esophageal spasm (DES), and jackhammer esophagus (JE) has not been well demonstrated. The aim of this international multicenter study was to assess clinical outcomes of POEM in patients with non-achalasia disorders, namely DES, JE, and EGJOO, in a large cohort of patients. PATIENTS AND METHODS: This was a retrospective study at 11 centers. Consecutive patients who underwent POEM for EGJOO, DES, or JE between 1/2014 and 9/2016 were included. Rates of technical success (completion of myotomy), clinical response (symptom improvement/Eckardt scoreâ≤â3), and adverse events (AEs, severity per ASGE lexicon) were ascertained . RESULTS: Fifty patients (56â% female; mean age 61.7 years) underwent POEM for EGJOO (nâ=â15), DES (nâ=â17), and JE (nâ=â18). The majority of patients (68â%) were treatment-naïve. Technical success was achieved in all patients with a mean procedural time of 88.4â±â44.7âmin. Mean total myotomy length was 15.1â±â4.7âcm. Chest pain improved in 88.9â% of EGJOO and 87.0â% of DES/JE ( P â=â0.88). Clinical success was achieved in 93.3â% of EGJOO and in 84.9â% of DES/JE ( P â=â0.41) with a median follow-up of 195 and 272 days, respectively. Mean Eckardt score decreased from 6.2 to 1.0 in EGJOO ( P â<â0.001) and from 6.9 to 1.9 in DES/JE ( P â<â0.001). A total of 9 (18â%) AEs occurred and were rated as mild in 55.6â% and moderate in 44.4â%. CONCLUSION: POEM is effective and safe in management of non-achalasia esophageal motility disorders, which include DES, JE, and EGJOO.
