Have you ever wondered.
*Appendicitis. It can be done without going under the knife.
No scars are left behind.
The recovery after surgery is fast.
Internet.
The appendix can be removed without removal
With the continuous development of minimally invasive concepts and technologies, the current minimally invasive surgical methods for appendicitis include laparoscopic appendectomy, appendectomy through natural orifice surgery (notes surgery), etc., however, all procedures are appendectomy.
Internet.
The latest studies have shown that the appendix is rich in lymphoid tissue, which can participate in cellular and humoral immunity, and can be classified as a central immune organ.

No appendiceal excision**
Endoscopic retrograde appendicitis** surgery (ERAT), pioneered by Professor Liu Bingrong of the First Affiliated Hospital of Zhengzhou University in 2010, achieves the purpose of rapidly reducing the pressure in the appendix cavity and reducing inflammation through intubation, imaging, irrigation, drainage and other operations, while preserving the intact appendix.
ERAT has the advantages of no incision, less trauma, and faster postoperative recovery.
Internet.
Conventional ERAT surgery is done under X-ray imaging, by injecting a contrast agent into the appendix cavity to show the condition of the appendix space (whether there is obstruction, stenosis, fecal stones, etc.) under X-ray, and then take targeted measures (stone extraction, basket stone removal, stent placement, etc.).
The images obtained in this way are indirect images, and due to radiation, they are not suitable for special populations such as pregnant women and children.
Internet.
With the rapid development of endoscopic technology, the "Eyemax" visual endoscopic imaging system has been maturely applied to ERAT.
To put it simply, the visual ERAT is to insert the imaging catheter into the appendix cavity through the colonoscopy, and the "EyeMax" visual endoscopic imaging system illuminates the appendix cavity, the last section of the digestive tract, just like the gastrointestinal endoscope illuminates the gastrointestinal tract, and the appendix cavity can be observed under direct vision, and at the same time, stones can be removed and rinsed under direct vision.
Visualize the ERAT step
1.Insertion of a guidewire through the endoscopic appendix cavity: the appendix opening is often covered by Gerlach's valve, which can be pushed open using a tapered transparent cap and the guidewire inserted retrograde by the appendix.
2.The "EyeMax" visual endoscopic imaging system enters the appendix: after the guidewire is successfully intubated, the visualizer enters the appendix along the guidewire to explore the situation in the appendix cavity.
3.Patients with fecal obstruction in the lumen may be given endoscopic stone removal** at the same time.
Visualize the advantages of ERAT technology
1.Fast recovery.
After decompression of the appendix cavity, the patient's pain is quickly relieved, and the patient can immediately resume his daily activities to avoid post-surgical incision pain.
2.Minimal trauma and no scarring.
The ERAT technique is less invasive, scarless, quick and convenient to operate, and preliminary clinical results show that the patient has no complications such as bleeding, perforation, and periappendiceal abscess formation.
3.The appendix is left intact.
Underlying appendiceal physiology is preserved.
4.No rays.
This technology does not require radiation throughout the process, which protects the patient and the surgeon, and is also suitable for special populations such as pregnant women and children.
5.Precise under direct gaze**.
The blind area of the previous gastrointestinal endoscopy is projected into a high-definition image on the electronic screen, and the doctor can directly observe, once the lesion is found, the accurate location can be obtained at the first time, and related surgical operations can be carried out through the ultra-fine biopsy orifice, such as irrigation, stone removal, lithotripsy, etc.
Internet.
Suitable for visualization of ERAT indications: Patients with acute and chronic appendicitis caused by various reasons without necrotic perforation are suitable for visualization ERAT, such as acute appendicitis with appendiceal stone obstruction, appendicitis reversal, high pressure in the purulent cavity of the appendix, local stenosis of the appendix cavity, etc.
Unsuitable: Endoscopy should not be performed for abdominal infection caused by perforation in complex cases, narrowing of the lower end of the intestine, difficulty in passing colonoscopy, etc.**;Those who cannot tolerate endoscopy and those who cannot undergo bowel preparation are not suitable for this procedure.
