Gastroenterology & Endoscopy

Ever wondered about the precision of medical instruments, how they are measured, or who pioneered this system? Join us on a captivating journey as we unearth the intriguing world of medical instrument measurements. We'll highlight the life and contributions of Swiss-French artisan, Joseph Frederick Benoit Chariere, the brain behind the French or Chariere gauge system. Used widely in endoscopy units worldwide, Chariere's precision instrument designs changed medical science forever. We'll discuss everything from scissors to syringes, anesthesia systems, and his innovative gauge system known for its uniform increments.

As we navigate the practical application of the French scale, you'll experience how it aids medical professionals in delivering precise treatments. Our discussion breaks down the complexities of this fascinating system and reveals its role in delivering vital medical equipment like catheters and stents. To bring it all to life, we'll delve into an exciting case study of balloon-assisted endoscopic retrograde colongeopancreatography, illuminating the importance of these measurements in real-world applications. Stay tuned for this engaging exploration into the precision and innovation that is at the heart of medical science.

Gastric antral vascular ectasia (GAVE) or watermelon stomach is an uncommon but important cause of gastrointestinal bleeding and anemia, first described in 1953 by Rider et al (1). GAVE is characterized by a “characteristic” endoscopic pattern, mainly represented by red spots either organized in stripes radially departing from pylorus (“watermelon stomach”, or arranged in a diffused-way or “honeycomb stomach”). In addition, there is a nodular variety, where there are multiple enlarged and nodular folds in the antrum (2, 3). Despite this GAVE is often misclassified or mis-diagnosed.

- Importance of having a range of endoscopic tools
  - Different types of tools (snares, basket nets, caps, over tubes, etc.)
  - Choosing the right tool
  - Teeth for firm grip on foreign bodies

- Dealing with capsule endoscopes in the GI tract
  - 1% getting stuck in the small bowel
  - Double balloon enteroscopy for removal
  - Visualizing strictures and ulcers via fluoroscopy
  - Preferred retrieval method: Rothnet or plain snares

- Extraction of gastric bands that migrate into the stomach
  - Discomfort caused by migrated bands
  - Use of gastric band cutters or biliary wire and lethal triptor device
  - Requires patience and persistence

- Challenges of migrated stents in the esophagus
  - Dilation of strictures can help
  - Pushing the stent into the stomach with an overt tube and cap
  - Grabbing the stent by its string and being gentle to avoid damage

- Increase in tight strictures in the esophagus possibly caused by ingestion of pills
  - Standard practice to inject contrast after dilation for safety
  - Reducing risks of perforation or damage

- Mastering foreign body extraction in GI endoscopy
  - Importance of equipping oneself with a diver

- Introduction to the management of colon polyps with thick and long stalks
  - Description of pedunculated polyps, specifically Paris zero ippy type with substantial stalk
  - Increased risk of bleeding during or post removal due to arteries in the stalk

- Interventions to prevent postpolipectomy bleeding
  - Mention of clipping injection and endoloop techniques
  - Possibility of using a combination of these techniques

- Explanation of endoloops and their operational difference from snares
  - Visual comparison between endoloops and snares
  - Endoloops lack the ease of opening and closing like snares

- Standard procedure for endoloop placement
  - Passing a catheter equipped with the endaloop above the polyp head
  - Incremental reveal of the loop while guiding it to encircle the polyp head

- Goal of snugly wrapping the endoloop around the polyp stalk
  - Positioning the loop about ten from the base of the stalk
  - Tightening the loop using the pushing ring or band

- Color transformation of the polyp head and commencement of resection
  - Polyp head changes to a blue or purplish hue
  - Three stages of polyp removal: firm clenching, coagulation current, and cutting current

- Caution regarding the use of clips
  - Need for vigilance to avoid complications with clips
