Pharyngeal Swallowing

Objectives This study aimed to demonstrate the feasibility of a novel high-resolution manometry (HRM) system, and to establish normal values of swallowing pressures along the velopharynx and upper esophagus. Methods 33 asymptomatic adult Japanese controls were studied. A solid-state HRM assembly with 36 circumferential sensors spaced 1 cm apart was positioned to record pressures during swallowing from the velopharynx to the upper esophagus. The maximum values of the swallowing (dry and 5 ml of water) pressures at velo, meso-hypopharynx, and at the upper esophageal sphincter (UES) were measured. The resting UES pressure, the length of the part in the cervical esophagus showing the resting UES pressure, and the distance from the nostril to the above-mentioned points of pressure were also measured. Results The maximum value of dry and water swallowing pressures at the velopharynx, meso-hypopharynx and UES, and the distances from the nasal vestibulum to each point were 132.3±61.3 (mmHg, mean ± standard deviation), and 146.5±77.5, 171.6±52.0, and 176.3±74.4, 163.5±70.6, and 239.3±80.1, and 9.8±1.2 (cm), and 9.8±1.3, 13.6±1.6, and 13.7±1.5, 17.0±1.9 and 17.1±1.6, respectively. The maximum value of the resting USE pressure, the length of the part in the cervical esophagus showing the resting USE pressure, and the distance from the nostril to the mid-point of the length of the resting UES pressure were 66.6±28.1 mmHg, 3.8±0.7 cm, and 18.2±1.6 cm, respectively. Conclusions The present study provides anatomical and physiological information about normal swallowing along the velopharynx and upper esophagus, which will be an aid to future clinical and investigative studies.

Objectives This study aimed to investigate the effects of a tongue-holding maneuver (THM) during swallowing, using a novel high-resolution manometry (HRM) system. Methods 27 asymptomatic adult Japanese controls were studied. A solid-state HRM assembly with 36 circumferential sensors spaced 1 cm apart was positioned to record pressures during swallowing from the velopharynx to the upper esophagus. The maximum values of the dry swallowing pressures at meso-hypopharynx, the upper esophageal sphincter (UES) and the mean values at meso-hypopharynx with and without THM were measured. Results The maximum values of dry swallowing pressures with and without THM were 195.0±77.2 (mmHg, mean ± standard deviation), and 178.1±53.0 at the meso-hypopharynx, and 213.4±74.0 and 190.0±95.0 at the UES, respectively. The mean values with and without THM at meso-hypopharynx were 47.4±11.9, and 44.0±11.2, respectively. The maximum value at UES (p=0.0347), and the mean value at the meso-hypopharynx (p=0.0124) of dry swallowing pressures with THM were significantly higher than those without THM. Conclusions These findings indicate that the THM has a potential to facilitate compensatory swallowing power at the pharynx and upper esophagus. HRM will provide us with important information about the swallowing physiology, and pathophysiology along the velopharynx, and upper esophagus.

Aim. Current recommendations of the Russian Gastroenterological Association on clinical use of high-resolution manometry in diagnosis of esophageal disorders are intended to assist in clinical decision making, terminology standardisation and interpretation of clinical data.Key points. In 2018, a joint meeting of the Russian Gastroenterological Association and Russian Neurogastroenterology and Motility Group approved unified terminology and classification of esophageal motor function disorders for high-resolution manometry diagnosis.Gastrointestinal patient complaints typically concern esophageal disorders such as dysphagia, regurgitation, heart-burn, chest pain or belching. To exclude erosive and ulcerative lesions, eosinophilic esophagitis and organic changes, esophagogastroduodenoscopy and biopsy are recommended in pre-treatment. Upon excluding mucosal lesions and esophageal lumen obstruction as causal for symptoms, use of high-resolution manometry is recommended. This method of esophageal examination has become the “gold standard” in diagnosis of motor disorders.High-resolution manometry enables detailed investigation of integral quantitative and qualitative characteristics of esophagus motor function and specific related disorders, analysis of esophageal contractile propagation and strictly coordinated synchronous peristalsis of upper esophageal sphincter, esophagus and lower esophageal sphincter, which malfunction may provoke development of achalasia, esophagospasm, hiatal hernia, ineffective eso pha geal motility and other motor disorders.Conclusion. High-resolution manometry is a relatively new method for study of esophagus motor function gaining increasingly wide application in clinical practice. It enables a medical professional to obtain evidence that may critically affect the choice of optimal patient care strategy and effective treatment. Current recommendations are based on an extensive review of up-to-date information and will be updated with new corpus of clinical data and assessment emerging in evidential medicine to provide gastroenterologists country-wide with latest scientific and practical guidelines.
