Summary: This study retrospectively analyzed the failure rate of esophagogastric junction (EGJ) insertion during high-resolution manometry (HRM) and reported the use of guidewire-assisted procedures. The results showed that insertion of a water-perfused HRM probe using an endoscopically-placed nasogastric guidewire allowed successful assessment of EGJ and esophageal peristalsis in cases where EGJ traversal was not possible.

Summary: This study describes the expected endoscopic and histological changes at the gastro-esophageal junction (GEJ) and defines diagnostic paradigms for Barrett esophagus (BE) post-sleeve gastrectomy (SG).

Summary: This study examined the effect of topical nasal anesthetic (TNA) on swallowing and tolerability during high-resolution impedance manometry (HRIM) with a 4.2-mm catheter. The results showed that TNA did not improve comfort or significantly affect swallowing behavior during the procedure.

Summary: The aim of this study was to provide a complete set of HRM data for patients with a normally functioning fundoplication. The results showed that the addition of a fundoplication significantly increased the values of the lower esophageal sphincter. The previously accepted upper limit defining esophageal outflow obstruction may not be clinically applicable after fundoplication.

Summary: This study examines the impact of HRM characteristics, such as abnormal motility and DCI, on surgical decision-making at the GE junction. The results show that HRM altered the planned procedure in over 50% of cases.

Summary: This study found that there are significant differences in results obtained by different operators during high-resolution anorectal manometry (HRM), despite using similar instructions. These differences may have a significant impact on the diagnoses and therapies offered to constipated patients.

Summary: The study aimed to investigate the prevalence of abnormal esophageal motor patterns in healthy individuals. Results showed that motor abnormalities are infrequent in healthy individuals and consist mainly of ineffective esophageal motility (IEM), with lower proportions when using stringent criteria in the supine position. Thresholds for HRM metrics varied across HRM systems and study positions.

Summary: Colonic high-resolution manometry (HRM) is a novel diagnostic method used in chronic constipation. This study aimed to determine agreement for motor pattern identification with HRM, and results showed substantial or high interobserver agreement for most motor patterns, supporting its use in clinical and research settings.

Summary: This study demonstrated significantly different pressure values obtained with different types of catheters. Normal ranges for conventional manometry cannot be applied to high-resolution systems, and results obtained by different types of manometry cannot be compared without adjustments.

Summary: Jackhammer esophagus is a rare esophageal motility disorder that can cause symptoms like dysphagia. High-resolution manometry and upper gastrointestinal endoscopy are key in diagnosis, with treatment options including calcium channel blockers and proton pump inhibitors.

Summary: The study found that patients prefer atomized lidocaine for increased comfort during pharyngeal high-resolution manometry procedures. While no significant differences were detected in pharyngeal pressure measurements between the two groups, the use of atomized lidocaine did not affect measurement outcomes.

Summary: This study investigated the effects of sildenafil on secondary peristalsis using HRM and found that sildenafil reduces the success rate and vigor of secondary peristalsis, similar to its effects on primary peristalsis.

Summary: This study suggests that constipated men and women exhibit different recto-anal pressure patterns, with women being more prone to defecatory disorders and men being more likely to have abnormal balloon expulsion tests. These findings are independent of sex-specific physiological differences.
