Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

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

Endoscopic Procedures III: Video Capsule Endoscopy

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, unexplained...

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

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 II: Colonoscopy

Endoscopic Procedures II: Colonoscopy

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 I: Esophagogastroduodenoscopy

Endoscopic Procedures I: Esophagogastroduodenoscopy

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:

Background:

Computer assistance in surgery is limited, especially for soft tissue interventions.
Existing systems focus on diagnostics and rigid structures, with limited application in soft tissue surgery.
Endoscopic surgery presents unique challenges for image guidance due to perceptual limitations.

Purpose of the Study:

To review computer-assisted navigation systems for soft tissue surgery.
To focus on applications in endoscopic thoracic and abdominal surgery.
To inform about new trends and technologies in computer-assisted surgery.

Main Methods:

Review of existing literature on computer-assisted navigation systems.
Analysis of approaches applicable to endoscopic thoracic and abdominal surgery.
Identification of challenges and benefits in endoscopic navigation.

Main Results:

Computer-assisted navigation systems aim to improve localization, critical structure observation, and tissue sparing.
Key research areas include addressing organ shift, tissue deformation, and system-surgeon communication.
Endoscopic navigation offers potential benefits despite perceptual limitations.

Conclusions:

Computer-assisted navigation is crucial for advancing soft tissue surgery, especially in endoscopic procedures.
Further development is needed to overcome challenges in organ shift, deformation, and system integration.
Endoscopic navigation represents a significant advancement in computer-aided medical procedures.
