Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.2K
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

6.6K
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 Endoscopy

1.5K
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 I: Esophagogastroduodenoscopy

2.4K
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: Colonoscopy

1.3K
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:

Area of Science:

  • Colorectal Surgery
  • Gastroenterology
  • Oncology

Background:

  • Transanal endoscopic microsurgery (TEMS) is an established technique for rectal specimen resection.
  • Existing endoscopic treatments are complemented by TEMS for benign rectal conditions.
  • TEMS has evolved for early rectal cancer, altering standard treatment algorithms.

Purpose of the Study:

  • To review the role and evidence for TEMS in benign rectal conditions.
  • To present the evolution, concepts, and outcomes of TEMS in early rectal cancer.
  • To discuss the future of TEMS in organ-preserving early rectal cancer treatment.

Main Methods:

  • Literature review of TEMS applications in benign and early malignant rectal conditions.
  • Analysis of treatment outcomes and patient selection for TEMS.
  • Examination of combination treatments involving TEMS and radiotherapy.

Main Results:

  • TEMS provides accurate resection for benign rectal conditions.
  • TEMS is increasingly utilized for early rectal cancer, enabling organ preservation.
  • Patient selection for neoadjuvant, radical, or combination treatments is becoming more precise.

Conclusions:

  • TEMS is a valuable tool for both benign rectal diseases and early rectal cancer.
  • The technique facilitates organ preservation and personalized treatment strategies.
  • Further research is needed on TEMS combined with radiotherapy for optimal outcomes.
