Endoscopic Procedures I: Esophagogastroduodenoscopy

Endoscopic Procedures I: Esophagogastroduodenoscopy

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:

Suctioning the Nasopharyngeal Airway

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Pressure Relationships in Thoracic Cavity

Pressure 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...

Tracheostomy Suctioning I: Pre-Procedural Steps

Tracheostomy Suctioning I: Pre-Procedural Steps

Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...

Summary

Sialendoscopy irrigation can cause salivary duct swelling. Maintaining intraductal pressure below 400 daPa minimizes duct trauma and reduces post-procedure inflammation and edema.

Area of Science:

Otolaryngology
Salivary Gland Surgery
Minimally Invasive Procedures

Background:

Sialendoscopy, a minimally invasive procedure for salivary gland disorders, can lead to post-operative swelling and infection.
Intraductal pressure from irrigation fluid is a suspected cause of salivary duct damage during sialendoscopy.

Purpose of the Study:

To investigate the relationship between intraductal pressure during sialendoscopy and salivary ductal tissue changes.
To establish safe pressure limits for irrigation fluid during sialendoscopy.

Main Methods:

Physiological intraductal pressures during sialendoscopy were measured.
Simulated intraductal pressures were applied to excised salivary glands.
Histological analysis of salivary gland tissue was performed.

Main Results:

Normal intraductal filling pressure ranges from 100-250 daPa, with flushing peaks up to 2000 daPa.
Pressures exceeding 400 daPa caused dilatation of salivary ducts and acinar areas.
No direct histological damage to duct structures was observed at tested pressures.

Conclusions:

Irrigation during sialendoscopy should be intermittent, not continuous.
Intraductal filling pressure should be kept below 400 daPa to minimize salivary duct trauma.
Adhering to pressure limits may reduce the risk of post-sialendoscopy edema and inflammation.
