RESUMEN
OBJECTIVES: The impact of ineffective esophageal motility (IEM) on gastroesophageal reflux disease (GERD) remains unknown, and abnormal esophageal motility often coexists with abnormal gastric motility. We aimed to investigate the role of IEM in GERD and its relationship with gastric electrical activity. METHODS: Patients diagnosed as GERD based on GERD-questionnaire score ≥8 in our hospital from January 2020 to June 2022 were included. All patients underwent 24-h multichannel intraluminal impedance-pH monitoring, high-resolution manometry, and electrogastrogram and were categorized into the normal esophageal motility (NEM) and IEM groups, respectively. Reflux characteristics and gastric electric activity were compared between the two groups, and the correlation between gastric electric activity and reflux was analyzed. RESULTS: Acid exposure time, total reflux episodes, and DeMeester score in the IEM group were higher than those in the NEM group. Distal mean nocturnal baseline impedance was significantly lower in the IEM group. Compared with the NEM group, the power ratio (PR) of fundus, antrum and pylorus and premeal and postmeal normal wave ratio of antrum were significantly lower in IEM. The total reflux episodes were negatively correlated with the PR of fundus and pylorus, and the DeMeester score was negatively correlated with the PR of corpus and pylorus. CONCLUSIONS: IEM may lead to increased reflux, resulting in esophageal mucosal damage. There may be consistency between abnormal esophageal motility and gastric motility.

OBJECTIVE: We aimed to identify the differences in symptoms, high-resolution manometry (HRM) characteristics, and the efficacy of peroral endoscopic myotomy (POEM) regarding patients' sex in achalasia. METHODS: All patients diagnosed with achalasia by HRM who underwent POEM and were followed up for more than 6 months were included. The individual characteristics, symptoms and signs, POEM findings, HRM results and potentially related complications in male and female patients were reviewed. RESULTS: Prior to POEM, dysphagia was more severe in female than male patients (P = 0.044), while regurgitation was more severe (P = 0.013) and heartburn was more common in male patients (P = 0.003). Regarding HRM characteristics, the lower esophageal sphincter pressure (LESP) was higher (P = 0.01) and length of esophagus was shorter in female patients than in male patients. Eckardt scores, LESP and integrated relaxation pressure were significantly improved after the POEM procedure (P < 0.001). No significant difference was observed between the sexes regarding the efficacy of POEM, reflux symptoms, HRM data and complications after POEM. CONCLUSIONS: Before they seek treatment, female patients with achalasia may experience severe dysphagia and male patients are more likely to experience heartburn and more severe regurgitation. POEM is a safe and effective option for treating both male and female patients with achalasia.

OBJECTIVE: To explore the correlation between reflux disease and abnormal esophageal motility in patients with gastroesophageal reflux disease (GERD). METHODS: Participants (patients with GERD and controls) who underwent 24-h impedance-pH monitoring (MII-pH monitoring) and high-resolution manometry between January 2012 and February 2017 were retrospectively studied. The patients were divided into two groups (acid reflux and nonacid reflux) based on their MII-pH monitoring data. Reflux episodes, endoscopic findings, and esophageal dynamic parameters were assessed and compared. RESULTS: A total of 142 patients were included (acid reflux [n = 58], nonacid reflux [n = 60], control group [n = 24]). There were more patients with esophagitis and more severe esophageal mucosal injury in the acid reflux group than in the nonacid reflux group. The acid reflux group had reduced lower esophageal sphincter (LES) basal pressure, shorter LES length, lower esophageal pressure and distal contractile integral index than the nonacid reflux group. Patients in the acid reflux group had more large breaks and a higher incidence of type II and III esophagogastric junction morphology than those in the nonacid reflux group. Acid exposure time, the incidence of long-term acid reflux, recumbent acid reflux, and the incidence of acid and nonacid reflux had a significant negative correlation with esophageal body motility or LES function. CONCLUSION: This study suggests that an increase in esophageal acid exposure is correlated with an increase in esophageal dysmotility in patients with GERD.

To determine the relationship between baseline impedance levels and gastroesophageal reflux, we retrospectively enrolled 110 patients (54 men and 56 female; mean age, 51â±â14 years) with suspected gastroesophageal reflux disease (GERD) who underwent 24-h multichannel intraluminal impedance and pH monitoring. Patients were stratified according to symptom (typical or atypical) and reflux types (acid reflux, nonacid reflux [NAR], or no abnormal reflux). Mean nocturnal baseline impedance (MNBI) were measured 3âcm (distal esophagus) and 17âcm (proximal esophagus) above the lower esophageal sphincter. Median distal esophageal MNBI was lower in the acid reflux group (1244âΩ; 647-1969âΩ) than in the NAR (2586âΩ; 1368-3666âΩ) or no abnormal reflux groups (3082âΩ; 2495-4472âΩ; all Pâ<â.05). Distal MNBI were negatively correlated with DeMeester score and acid exposure time. Atypical symptoms were more frequently associated with NAR than typical symptoms (Pâ<â.01). Among patients with positive symptom-association probability (SAP) for NAR, median proximal MNBI tended to be lower in patients with typical symptoms (median, 3013âΩ; IQR, 2535-3410âΩ) than in those with atypical symptoms (median, 3386âΩ; IQR, 3044-3730âΩ, Pâ=â.05). Thus, atypical GERD symptoms were more likely to be associated with NAR. The mucosal integrity of the proximal esophagus might be relatively impaired in GERD patients with typical symptoms for NAR.

OBJECTIVE: To assess the prognostic value in Chinese patients of two new systems, the World Health Organization (WHO)-2010 and the American Joint Committee on Cancer and the Union for International Cancer Control (AJCC/UICC) systems, for the classification of gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN). METHODS: One hundred and three patients with GEP-NEN treated at the First Affiliated Hospital of Nanjing Medical University from January 2003 to December 2011 were included in the study. All patients were diagnosed pathologically and had complete follow-up data. Univariate and multivariate analyses of their clinicopathological characteristics were performed. RESULTS: The 5-year survival rates were 95%, 74%, 24% and 15% based on the AJCC/UICC stages I to IV, and 92%, 62% and 29% according to WHO-2010 grades 1 to 3, respectively, in patients with GEP-NEN. A higher mortality was observed in patients with AJCC/UICC stage III and IV tumors compared with those at stage I-II, and patients with stage II compared with those with stage I, whereas there was no difference in survival between stage IV and III patients. Based on the WHO-2010 grading classification, patients with grade 3 tumors had the lowest survival rate than those with grade 1 and 2 tumors, followed by patients with grade 2 tumors. CONCLUSION: The WHO-2010 and AJCC/UICC staging systems can effectively evaluate the prognosis of patients with GEP-NEN, although the latter might not accurately discriminate the prognosis of patients with local metastasis from those having distant metastasis.
