Intraluminal pressures generated during esophageal bougienage
Gastroenterology
|November 1, 1981
Summary
Esophageal bougienage pressure was measured during dilation for strictures. Maximal pressures varied significantly, influenced by stricture age and dilator size, providing key insights into esophageal wall response.
Area of Science:
- Gastroenterology
- Medical Devices
- Physiology
Background:
- Esophageal bougienage is a common palliative treatment for esophageal strictures.
- The pressures exerted on the esophageal wall during bougienage are not well understood.
Purpose of the Study:
- To measure and characterize the esophageal wall pressure during bougienage for reflux-induced lower esophageal strictures.
- To investigate factors influencing pressure generation, such as stricture characteristics and dilator size.
Main Methods:
- Water-perfused catheters were radially implanted into Maloney dilators.
- Esophageal wall pressure was monitored in 13 patients undergoing bougienage for strictures and 11 control patients.
Main Results:
- Maximal esophageal wall pressure ranged from 25 to 830 mmHg in patients with strictures.
- Higher pressures were observed with newly dilated strictures and larger bougies.
- Resting esophageal wall pressure in controls was 5 mmHg, similar to stricture patients.
Conclusions:
- This study quantifies esophageal wall pressures during bougienage, revealing significant variability.
- Findings highlight the impact of stricture status and dilator size on pressure dynamics.
- The data contributes to understanding esophageal wall response to dilation procedures.

01:24Pressure Relationships in Thoracic Cavity
Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs during...

01:24Pulmonary Ventilation: Inhalation
Pulmonary ventilation is a vital process that ensures the exchange of oxygen and carbon dioxide in the lungs. It refers to the movement of air into and out of the lungs, enabling the body to obtain oxygen and remove waste carbon dioxide. In this article, we will explore the intricacies of pulmonary ventilation, including its underlying principles, mechanisms, and the interplay of pressures within the respiratory system.

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

01:27Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
01:25Gastroesophageal Reflux Disease
Gastroesophageal reflux disease (GERD) is the backward flow of stomach contents (acid, pepsin, or bile) into the esophagus, causing mucosal inflammation known as esophagitis. It results from failure of antireflux mechanisms, mainly the lower esophageal sphincter (LES), influenced by mechanical and physiological factors.Etiology and Risk FactorsGERD develops when LES function is weakened or when intra-abdominal pressure increases. Risk factors include aging, obesity, and sliding hiatal hernia,...
