Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

174
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 Laproscopy

150
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...

Urologic Endoscopic Procedure: Cystoscopic Examination

252
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

313
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

764
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.

Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

335
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
This summary is machine-generated.

Updated guidelines recommend endocervical curettage (ECC) for specific high-risk patients undergoing colposcopy. ECC is preferred for women over 40 and those with high-grade cytology or HPV 16/18 infection.

Area of Science:

  • Gynecology
  • Oncology
  • Cervical Cancer Screening

Background:

  • The 2017 Colposcopy Standards Consensus Guidelines in the US did not include recommendations for endocervical curettage (ECC).
  • Previous guidelines for ECC were established in 2012.
  • An expert workgroup convened in 2021 to update ECC guidelines.

Purpose of the Study:

  • To provide updated guidelines for the use of endocervical curettage (ECC) in patients referred for colposcopy.
  • To incorporate recent literature and data into ECC recommendations.

Main Methods:

  • A systematic literature review was conducted for studies published between 2012 and 2021.
  • Data from the NCI Biopsy study were analyzed.
  • An expert workgroup developed consensus guidelines based on the reviewed literature and data.

Main Results:

  • ECC is recommended for patients with high-grade cytology, HPV 16/18 infection, positive p16/Ki67 dual staining, prior cervical precancer treatment, or when the squamocolumnar junction is not visualized.
  • ECC is preferred for nonpregnant patients over 40 years old.
  • ECC may be omitted in specific cases, such as planned excisional procedures or in young, nulliparous patients with low-grade cytology, but is unacceptable in pregnancy.

Conclusions:

  • These updated guidelines for ECC supplement the 2017 colposcopy practice recommendations.
  • The guidelines aim to optimize the use of ECC in cervical cancer screening and management.
