Our Summary

This research is aimed at understanding how small areas of the small intestine (known as the jejunal arteries or JA) are supplied with blood, and how this affects the removal of certain types of tumors in the small intestine (specifically, small-intestinal neuroendocrine tumors or SI-NET).

The scientists conducted their research on six cadavers, conducting a detailed examination and taking measurements of the small intestine and its blood supply. They found that the first two jejunal arteries could potentially supply enough blood to a significant length of the small intestine, suggesting that it may be possible to remove stage III or higher small-intestinal neuroendocrine tumors while leaving only two jejunal arteries intact.

In simpler terms, this research suggests a method for removing certain types of advanced tumors in the small intestine that could potentially leave the patient with a functional length of intestine, reducing the risk of complications associated with having a shorter intestine.

Doctor’s Tip

A helpful tip a doctor might give a patient undergoing intestinal resection is to follow a strict post-operative diet plan to ensure proper healing and prevent complications. This may include gradually reintroducing solid foods, staying hydrated, and avoiding foods that may irritate the digestive system. It is also important to follow any recommendations for supplements or medications to support digestion and nutrient absorption. Additionally, regular follow-up appointments with your healthcare provider are essential to monitor your progress and address any concerns.

Suitable For

Patients who are typically recommended for intestinal resection include those with:

  1. Small-intestinal neuroendocrine tumors (SI-NET) that are stage III or higher.
  2. Tumors or obstructions in the small intestine that cannot be treated with other methods.
  3. Severe Crohn’s disease or other inflammatory bowel diseases that have not responded to medical treatment.
  4. Intestinal ischemia or infarction, where blood supply to the intestine is compromised.
  5. Intestinal perforation or severe trauma to the intestine.
  6. Intestinal strictures or blockages that are causing severe symptoms or complications.
  7. Intestinal fistulas or abscesses that are not responding to conservative treatment.

It is important for patients to undergo a thorough evaluation by a healthcare provider to determine if intestinal resection is the appropriate treatment option for their specific condition.

Timeline

Before intestinal resection:

  1. Patient presents with symptoms such as abdominal pain, weight loss, and changes in bowel habits.
  2. Patient undergoes diagnostic tests such as blood tests, imaging studies (CT scan, MRI), and endoscopy to determine the cause of their symptoms.
  3. Patient is diagnosed with a small-intestinal neuroendocrine tumor and treatment options, including surgery, are discussed.
  4. Patient undergoes pre-operative preparations such as bowel cleansing and fasting.

After intestinal resection:

  1. Patient undergoes surgery to remove the small-intestinal neuroendocrine tumor, which may involve removing a portion of the small intestine.
  2. Patient recovers in the hospital for a few days post-surgery, with close monitoring of their condition and pain management.
  3. Patient gradually resumes eating and drinking, starting with clear liquids and progressing to solid foods.
  4. Patient may experience side effects such as abdominal pain, bloating, and changes in bowel habits as their digestive system adjusts to the changes.
  5. Patient is discharged from the hospital and follows up with their healthcare team for monitoring and further treatment as needed.

What to Ask Your Doctor

  1. What is an intestinal resection and why is it necessary in my case?

  2. How will the removal of a section of my small intestine affect my digestion and absorption of nutrients?

  3. What are the potential risks and complications associated with an intestinal resection surgery?

  4. How long is the recovery process after an intestinal resection surgery?

  5. Will I need to make any changes to my diet or lifestyle after the surgery?

  6. What are the chances of the tumor returning after the intestinal resection?

  7. Are there any alternative treatment options to intestinal resection for my condition?

  8. How many jejunal arteries will be left intact during the surgery, and how will this affect the blood supply to my small intestine?

  9. What is the success rate of removing stage III or higher small-intestinal neuroendocrine tumors while leaving only two jejunal arteries intact?

  10. How will the preservation of two jejunal arteries potentially benefit me in terms of long-term gastrointestinal function and overall health?
