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 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:

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 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.

Summary

Intraoperative enteroscopy (IOE) is effective for minimally invasive surgery. This procedure aids in discovering additional intestinal lesions and tumors not detected preoperatively, improving patient diagnosis.

Area of Science:

Gastroenterology
Minimally Invasive Surgery
Endoscopy

Background:

Minimally invasive surgery offers benefits but can limit direct visualization of the small intestine.
Accurate preoperative diagnosis is crucial for effective surgical planning.

Purpose of the Study:

To evaluate the efficacy and safety of intraoperative enteroscopy (IOE) during minimally invasive surgery.
To determine the diagnostic yield of IOE in identifying intra-abdominal pathologies.

Main Methods:

A prospective study involving 12 patients undergoing minimally invasive surgery.
Intraoperative enteroscopy was performed after intestinal exteriorization via minilaparotomy.
A sterilized enteroscope was utilized for visualization.

Main Results:

The mean skin incision length was 5.7 cm.
An average of 334 cm of the small intestine was observed.
IOE identified additional lesions in 5/9 Crohn's disease patients and 1 ileal tumor missed preoperatively.
Two patients experienced postoperative complications.

Conclusions:

Intraoperative enteroscopy is an efficacious tool in the context of minimally invasive surgery.
IOE enhances diagnostic capabilities by revealing previously undetected intestinal abnormalities.
