Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

6.0K
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.

Imaging Studies for Cardiovascular System III: X-Ray

670
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

642
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...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.1K
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...

Imaging Studies I: CT and MRI

1.2K
Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Area of Science:

  • Medical Imaging
  • Gastroenterology
  • Radiation Safety

Background:

  • Endoscopic retrograde cholangiopancreatography (ERCP) traditionally uses pulsed or continuous fluoroscopy.
  • Minimizing radiation exposure is crucial for patient safety during ERCP procedures.

Purpose of the Study:

  • To evaluate the cumulative radiation exposure in patients undergoing ERCP using single-frame fluoroscopy.
  • To compare radiation doses across different ERCP complexity levels.

Main Methods:

  • Retrospective review of 400 ERCP procedures.
  • Data collected included fluoroscopy time (FT), total radiation dose, dose area product (DAP), and effective dose (ED).
  • ERCPs were categorized by a complexity score.

Main Results:

  • Single-frame fluoroscopy resulted in significantly lower FT, total radiation dose, DAP, and ED for complexity score 1 procedures.
  • Mean FT was 1.57 minutes, mean total radiation dose was 23.02 mGy, mean DAP was 3.62 Gy cm², and mean ED was 0.94 mSv.
  • No significant difference in radiation parameters was observed between successful and unsuccessful procedures.

Conclusions:

  • Successful ERCP can be achieved using solely single-frame fluoroscopy.
  • This technique demonstrates lower radiation exposure compared to previously reported methods in the literature.
