Bolus flow and biomechanical properties of the esophageal wall during primary esophageal peristalsis: Effects of bolus viscosity and posture

Ali Zifan et al.

Summary: Intraluminal impedance recordings can measure luminal distension in the esophagus. Factors such as posture and bolus viscosity affect bolus flow rate, esophageal wall tension, and esophageal wall distensibility during swallow-induced primary peristalsis.

Transient hypopharyngeal intrabolus pressurization patterns: Clinically relevant or normal variant?

Taher Omari et al.

Summary: Translating: In oropharyngeal dysphagia, impaired pharyngoesophageal junction (PEJ) opening is reflected by an elevated hypopharyngeal intrabolus pressure (IBP), quantifiable using pharyngeal high-resolution manometry with impedance (P-HRM-I). Transient intrabolus pressurization (TP) phenomena are not sustained and last for only a brief period. We hypothesized that TP patterns reflect impaired coordination between timing of hypopharyngeal bolus arrival and PEJ relaxation. Chinese Summary: Transient intrabolus pressurization (TP) in oropharyngeal dysphagia reflects mistimed coordination between bolus arrival and PEJ relaxation, with higher IBP and shorter PEJ relaxation time during TP swallows. In Patients, RT-DCL time difference correlated with IBP, suggesting pathological TP swallows impede bolus flow due to mistimed coordination. English Summary: In oropharyngeal dysphagia, transient intrabolus pressurization (TP) patterns may indicate impaired coordination between bolus arrival and PEJ relaxation, leading to an increased IBP and shorter PEJ relaxation time during TP swallows. The mistimed coordination in TP swallows may impede bolus flow and result in a brief period of pharyngeal chamber pressurization by muscular forces, with IBP correlating with RT-DCL time difference in Patients.

Rhythmic contraction but arrhythmic distension of esophageal peristaltic reflex in patients with dysphagia

Kazumasa Muta et al.

Summary: Patients with unexplained dysphagia show abnormalities in the distension phase of esophageal peristalsis, with faster bolus transit, smaller luminal cross-sectional area, and fragmented bolus flow compared to normals. These abnormalities are sensitive and specific markers of dysphagia, suggesting that the cause of dysphagia sensation may be due to esophageal contraction forcing the bolus through a narrow lumen esophagus.

Esophageal Bolus Domain Pressure and Peristalsis Associated With Experimental Induction of Esophagogastric Junction Outflow Obstruction

Wei-Yi Lei et al.

Summary: This study measured the effect of esophageal outflow obstruction induced by a leg-lift protocol on intrabolus pressures. The results showed an increase in relaxation pressure and distal contractile integral at the esophagogastric junction, as well as increased pressures in all bolus categories. Measuring pressures within the intrabolus domain can aid in confirming a diagnosis of EGJ outflow obstruction.

Novel gel bolus to improve impedance-based measurements of esophageal cross-sectional area during primary peristalsis

Melissa Ledgerwood et al.

Summary: This study compared novel gel bolus with other materials for impedance-based luminal distension measurement during swallowing-induced peristalsis. The novel gel bolus showed the least amount of air in the bolus during passage through the esophagus and had the best correlation between US measured CSA and nadir impedance value in both supine and Trendelenburg positions. Using the novel gel bolus is suggested for assessing distension and contraction during routine clinical HRM testing.

Rena Yadlapati et al.

Summary: CCv4.0 is an updated classification scheme for esophageal motility disorders using HRM, developed by fifty-two international experts in seven subgroups over two years. Key updates include a more rigorous and expansive HRM protocol, refined definition of EGJOO, stricter criteria for ineffective esophageal motility, and description of baseline EGJ metrics. These changes aim to provide more standardized criteria for disorders of peristalsis and obstruction at the EGJ.

Distension-contraction profile of peristalsis in patients with nutcracker esophagus

Ali Zifan et al.

Summary: The study found that patients with nutcracker esophagus have smaller amplitudes of distension and contraction during swallow-induced peristalsis compared to normal subjects, but greater amplitude of contraction. Additionally, there are abnormalities in the temporal relationship between distension and contraction in patients, which may contribute to dysphagia.

Esophagogastric junction outflow obstruction

Albert J. Bredenoord et al.

Summary: EGJOO is defined as an elevated IRP and IBP during wet swallows and persistently elevated IRP in the upright position according to CCv4. A conclusive diagnosis requires a manometric diagnosis of EGJOO and associated symptoms supported by additional investigations, with history and endoscopic evaluation being crucial for excluding secondary causes. Proposed changes in CC4.0 aim to improve specificity of diagnosis and reduce clinically irrelevant diagnoses.
