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:

Ultrasound II: Endoscopic Ultrasound and FibroScan

Endoscopic Ultrasound (EUS) and FibroScan are valuable diagnostic tools in gastroenterology and hepatology, each with specific applications and techniques.
Endoscopic Ultrasound (EUS):

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...

Urodynamic Studies: Uroflowmetry

Urodynamic Studies: Uroflowmetry

Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Endoscopic Procedures II: Colonoscopy

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Summary

Laser Doppler flowmetry assessed gastric microcirculation during esophagogastrostomy. Results indicate that performing this procedure 5-6 cm from the right gastroepiploic artery termination increases risks of anastomosis failure and stenosis.

Area of Science:

Gastrointestinal surgery
Vascular surgery
Medical device technology

Context:

Esophagogastrostomy is a critical procedure in gastric surgery.
Assessing gastric wall microcirculation is vital for surgical success.
Laser Doppler flowmetry offers a method for real-time microvascular assessment.

Purpose:

To evaluate gastric wall microcirculation using laser Doppler flowmetry during esophagogastrostomy.
To identify critical distances from the right gastroepiploic artery termination that impact microcirculation.
To correlate microcirculatory changes with potential anastomosis complications.

Summary:

Laser Doppler flowmetry was used to assess gastric microcirculation in 22 patients undergoing esophagogastrostomy.
Impaired circulation was noted in stomach transplants positioned 5-6 cm from the right gastroepiploic artery termination.
Esophagogastrostomy at or proximal to this level elevates the risk of anastomosis failure and cicatricial stenosis.

Impact:

Provides objective data on microcirculatory changes during gastric surgery.
Highlights the importance of precise surgical planning to avoid compromised blood supply.
Informs surgical technique to reduce the incidence of anastomosis complications and improve patient outcomes.
