RATIONALE: Spontaneous breathing during mechanical ventilation increases transpulmonary pressure and tidal volume, and worsens lung injury. Intuitively, controlling tidal volume and transpulmonary pressure might limit injury from added spontaneous effort. OBJECTIVES: To test the hypothesis that during spontaneous effort in injured lungs, tidal volume and transpulmonary pressure limitation by volume-controlled ventilation results in less injurious patterns of inflation...

Manometry is used worldwide to assess motor function of the gastrointestinal tract, and the measured intraluminal pressure patterns are usually equated with contraction patterns. In the colon, simultaneous pressure increases throughout the entire colon are most often called simultaneous contractions, although this inference has never been verified. To evaluate the relationship between pressure and contraction in the colon we performed high-resolution manometry and measured diameter changes reflecting circular muscle contractions in the rabbit colon...

BACKGROUND: The joint hypermobility syndrome (JHS) is a common non-inflammatory connective tissue disorder which frequently co-exists with postural tachycardia syndrome (PoTS), a form of orthostatic intolerance. Gastrointestinal symptoms and dysmotility have been reported in PoTS. Dysphagia and reflux are common symptoms in JHS, yet no studies have examined the physiological mechanism for these, subdivided by PoTS status. METHODS: Thirty patients (28 female, ages: 18-62) with JHS and symptoms of reflux (n=28) ± dysphagia (n=25), underwent high-resolution manometry and 24 hour pH-impedance monitoring after questionnaire-based symptom assessment...

Chronic constipation is a common, persistent condition affecting many patients worldwide, presenting significant economic burden and resulting in substantial healthcare utilization. In addition to infrequent bowel movements, the definition of constipation includes excessive straining, a sense of incomplete evacuation, failed or lengthy attempts to defecate, use of digital manoeuvres for evacuation of stool, abdominal bloating, and hard consistency of stools. After excluding secondary causes of constipation, chronic idiopathic or primary constipation can be classified as functional defecation disorder, slow-transit constipation (STC), and constipation-predominant irritable bowel syndrome (IBS-C)...

INTRODUCTION: Surgical procedures for colonic replacement of the esophagus are most commonly associated with anastomotic stricture which cause dysphagia. In this report, we describe a rare case of a patient who demonstrated dysphagia resulting from an anastomotic stricture following esophageal replacement with the colon. All the treatments to dilate the anastomotic stricture were ineffective. To investigate the new treatment strategy for a case with complicated dysphagia, clinical dysphagia evaluations, functional oral intake scale (FOIS), videofluoroscopic swallowing study as well as high-resolution manometry were used to evaluate the swallowing function of the patient before and after treatments...

Symptoms of refractory gastroesophageal reflux disease (GERD) are commonly encountered in clinical practice. The aim of this study was to analyze the data obtained from questionnaires, high-resolution manometry (HRM), and ambulatory impedance-pH monitoring in patients with persisting GERD symptoms and to explore the possible underlying causes for this clinical presentation. After completing the questionnaires, the selected patients underwent endoscopy, HRM, and ambulatory impedance-pH monitoring. Based on the results of these investigations, we divided the patients into 4 groups: reflux esophagitis (RE), hypersensitive esophagus (HE), functional heartburn (FH), and nonerosive gastroesophageal reflux disease (NERD)...

The bolus volume has a modulating effect on the swallowing dynamics, but previously reported adaptations of the pharyngeal function have been inconsistent. Therefore, the aim of this study was to comprehensively evaluate changes of pressure and time parameters in the pharynx and upper esophageal sphincter (UES) in relation to the swallowed bolus volume with high-resolution manometry (HRM). To examine the normal swallowing physiology, particularly thin HRM probes were used, which were expected to influence the investigated structures only minimally...

Obstructed defecation is a complex disorder that results in impaired propagation of stool from the rectum. It is one of the major subtypes of functional constipation and can be secondary to either functional or anatomic etiologies. Patients with obstructed defecation typically present with symptoms of abdominal discomfort, a sensation of incomplete evacuation and rectal obstruction, passage of hard stools, the need for rectal or vaginal digitation, excessive straining, and reduced stool frequency. Evaluation of obstructed defecation is multimodal, starting with a thorough history and physical examination with focus on the abdominal, perineal, and rectal examination...

REVIEW
Isaac Payne, Leander M Grimm
Paradoxical puborectalis contraction (PPC) and increased perineal descent (IPD) are subclasses of obstructive defecation. Often these conditions coexist, which can make the evaluation, workup, and treatment difficult. After a thorough history and examination, workup begins with utilization of proven diagnostic modalities such as cinedefecography and anal manometry. Advancements in technology have increased the surgeon's diagnostic armamentarium. Biofeedback and pelvic floor therapy have proven efficacy for both conditions as first-line treatment...

High-resolution manometry (HRM) is currently the most important diagnostic test for esophageal motility disorders, providing information on the contraction pattern of the circular muscle layer, which helps classify these esophageal motor diseases. However, with the increasing development of ultrasound, other techniques, such as high-frequency intraluminal ultrasound (HFIUS), have gained importance. This technique uses a flexible shaft with a central wire integrated into a standard endoscope, which facilitates real-time sonography...

BACKGROUND: Obesity and gastroesophageal reflux disease (GERD) are major health problems showing an inconstant relationship in the literature. Therefore, anthropometric parameters which are predictive and can simply be assessed at first patient presentation may lead to a better patient selection for ambulatory reflux monitoring. We aimed to examine the association of body mass index (BMI) and waist to hip ratio (WHR) with gastroesophageal reflux activity during 24 hour-pH-impedance monitoring...
