Aneurysm II: Clinical Manifestations and Diagnostic Studies01:21

Aneurysm II: Clinical Manifestations and Diagnostic Studies

338
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Hypertension III: Clinical Manifestations and Diagnostic Studies

558
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

341
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Behavior of Concrete Under Compressive Load01:23

Behavior of Concrete Under Compressive Load

625
Concrete exhibits specific behaviors under different compressive loads. Understanding this is crucial for understanding its structural integrity. When concrete undergoes uniaxial compression, it tends to develop cracks that run parallel to the direction of the force. These parallel cracks stem from localized tensile stresses that occur perpendicular to the compression direction. Additionally, angled cracks may appear due to the formation of shear planes.
As the concrete specimen fractures under...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

579
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Imaging Studies IV: Magnetic Resonance Imaging

275
Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Area of Science:

  • Minimally invasive surgery
  • Gastrointestinal surgery
  • Biliary tract surgery

Background:

  • Bilioenteric anastomosis (BEA) is crucial for biliary tract reconstruction.
  • Magnetic compression anastomosis has shown feasibility in animal models.
  • Laparoscopic techniques offer advantages in minimally invasive surgery.

Purpose of the Study:

  • To evaluate the initial clinical experience of laparoscopically magnetic compression bilioenteric anastomosis (LMC-BEA).
  • To assess the safety and efficacy of LMC-BEA in patients with obstructive jaundice.

Main Methods:

  • Prospective enrollment of patients undergoing LMC-BEA from 2013 to 2015.
  • Laparoscopic placement of magnets and a drainage tube for anastomosis.
  • Postoperative follow-up including cholangiography and monitoring for magnet discharge.

Main Results:

  • Five patients (4 malignant obstructive jaundice, 1 benign biliary stricture) were included.
  • Median LMC-BEA time was 12 minutes; complete anastomosis confirmed in a median of 21 days.
  • No anastomotic complications (bile leakage, stricture) were observed during a median follow-up of 313 days.

Conclusions:

  • Laparoscopic magnetic compression is a promising alternative for BEA.
  • The initial clinical experience demonstrates the safety and efficacy of LMC-BEA.
  • No anastomotic complications occurred in the five patients who underwent LMC-BEA.
