Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

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...
Endoscopic Procedures II: Colonoscopy01:25

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 II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

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 to...
Suctioning the Nasopharyngeal Airway01:29

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.
Equipment Required
Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

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:

Summary

Endoscopic sinus surgery (ESS) significantly improves most chronic rhinosinusitis (CRS) symptoms. While nasal obstruction shows the greatest improvement, fatigue and bodily pain also see meaningful gains after ESS.

Area of Science:

  • Otolaryngology
  • Surgical Outcomes Research

Background:

  • Chronic rhinosinusitis (CRS) significantly impacts patient quality of life.
  • Endoscopic sinus surgery (ESS) is a common treatment for refractory CRS.

Purpose of the Study:

  • To synthesize recent evidence on the effectiveness of ESS for various CRS symptoms.
  • To analyze the impact of ESS on symptom severity, pain, fatigue, and psychological factors.

Main Methods:

  • Systematic review and meta-analysis of studies reporting CRS symptom outcomes post-ESS.
  • Inclusion of data from over 18 different survey instruments and symptom scoring systems.
  • Calculation of effect sizes for individual and pooled symptom improvements.

Main Results:

  • Most major CRS symptoms demonstrated significant improvement after ESS (overall effect size 1.19).
  • Nasal obstruction showed the largest improvement (effect size 1.73), while headache and hyposmia improved less.
  • Fatigue and bodily pain, often elevated in CRS patients, improved by a clinically meaningful degree (approx. 0.5 SD).

Conclusions:

  • ESS generally leads to comparable improvements across major CRS symptoms.
  • Associated symptoms like bodily pain and fatigue are positively impacted by ESS.
  • Depression is linked to lower quality of life pre- and post-surgery but does not confound symptom reporting.
