Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

350
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 Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

306
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...

Cardiac Catheterization I: Pre-Procedure Overview01:28

Cardiac Catheterization I: Pre-Procedure Overview

542
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

349
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...

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

1.6K
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.

Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

266
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Area of Science:

  • Orthopedic Surgery
  • Anatomy
  • Hand Surgery

Background:

  • Anatomical variations in the abductor pollicis longus (APL) muscle insertion.
  • Accessory or supernumerary distal APL bundles can cause issues.
  • Zancolli described a partial APL tenotomy for these variations.

Purpose of the Study:

  • To describe the surgical technique for a minimally invasive partial APL tenotomy.
  • To report the results and indications for this procedure.
  • To evaluate its use in trapeziometacarpal osteoarthritis.

Main Methods:

  • Anatomical and pathophysiological review.
  • Description of a minimally invasive, extra-capsular surgical technique.
  • Partial tenotomy of accessory or supernumerary distal APL bundles.

Main Results:

  • The technique is simple and minimally invasive.
  • It is indicated for Dell stage I or II trapeziometacarpal osteoarthritis.
  • Effective for pain relief when conservative treatment fails.

Conclusions:

  • Partial APL tenotomy is a viable surgical option for specific anatomical variations.
  • This technique offers a conservative surgical approach for early-stage trapeziometacarpal osteoarthritis.
  • It provides pain relief in patients unresponsive to non-operative management.
