Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

277
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 III: Video Capsule Endoscopy

426
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 Studies I: Bronchoscopy and Thoracoscopy

329
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 I: Esophagogastroduodenoscopy

515
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:

Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

328
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:

Summary

Endoscopic full-thickness resection (EFTR) with an over-the-scope clip (OTSC) offers a safe and effective method for removing difficult gastrointestinal lesions. This technique achieved a high rate of complete tumor removal (98.5%) with no recurrence during follow-up.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery
  • Oncology

Background:

  • Conventional endoscopic submucosal dissection (ESD) has limitations in achieving complete resection for certain mucosal and submucosal lesions.
  • Endoscopic full-thickness resection (EFTR) presents an alternative with a higher rate of microscopically margin-negative (R0) resection.
  • EFTR enables definitive diagnosis and treatment of lesions unsuitable for standard endoscopic resection.

Purpose of the Study:

  • To assess the efficacy and safety of EFTR when utilizing an over-the-scope clip (OTSC) for lesion removal.
  • To evaluate the R0 resection rates and adverse events associated with EFTR-OTSC procedures.
  • To determine the long-term outcomes and recurrence rates following EFTR-OTSC treatment.

Main Methods:

  • A prospective, single-center clinical trial involving 68 patients aged 18-70 years.
  • Inclusion criteria: gastric or colorectal submucosal tumors (SMTs) or early-stage cancers (≤20 mm) assessed by EUS and CT.
  • All lesions were treated with EFTR followed by OTSC for wound closure; data on demographics, lesion characteristics, R0 status, and follow-up were analyzed.

Main Results:

  • Successful EFTR and 100% OTSC defect closure were achieved in all 68 patients.
  • The mean procedure time was 39.6 minutes, with OTSC closure taking 5.0 minutes.
  • Histologically complete resection (R0) was obtained in 98.5% of patients, with a 16.2% rate of procedure-related adverse events and no recurrence during a mean follow-up of 48.2 months.

Conclusions:

  • EFTR in conjunction with OTSC is a highly effective and safe endoscopic technique.
  • This combined approach facilitates the complete removal of select subepithelial and epithelial lesions.
  • EFTR-OTSC is a viable option for lesions not amenable to conventional endoscopic resection methods.
