Ileal Interposition

 

Ileal interposition is a surgical procedure that involves re-routing a portion of the small intestine to a different location in the digestive tract. It is usually performed as a treatment for type 2 diabetes, although it may also be used to help people who are severely overweight (obese) lose weight. During the procedure, a section of the ileum, the final part of the small intestine, is disconnected from the rest of the intestine and moved to a location between the stomach and the rest of the small intestine.

 

What is Ileal Interposition Surgery?

 

Ileal Interposition (II) surgery is a type of bariatric surgery that involves rerouting the small intestine to a lower portion of the digestive tract. This procedure is typically performed in conjunction with gastric bypass surgery and is intended to enhance weight loss and improve obesity-related health conditions.

In II surgery, a portion of the small intestine is isolated and reconnected to the lower portion of the intestine, bypassing a portion of the small intestine that is responsible for absorbing calories. By bypassing this section of the intestine, the patient's body absorbs fewer calories from food, leading to weight loss.

II surgery is considered a complex procedure and carries a higher risk of complications compared to other bariatric procedures, such as a gastric sleeve or gastric bypass. It is typically recommended for patients with a high BMI and severe obesity-related health conditions who have not achieved significant weight loss with other bariatric procedures.

 

Who are Good Candidates for Ileal Interposition Surgery?

 

Good candidates for Ileal Interposition (II) surgery are individuals with a high body mass index (BMI) and severe obesity-related health conditions who have not achieved significant weight loss with other bariatric procedures, such as a gastric sleeve or gastric bypass. Individuals who want to be a candidate for II surgery should have some characteristics.

 

  • Have a BMI of 40 or greater or have a BMI of 35 or greater with obesity-related health conditions such as type 2 diabetes or sleep apnoea
  • Be committed to making lifestyle changes to maintain a healthy weight after surgery
  • Willingness to follow a strict diet and exercise regime after the procedure
  • Being free from medical conditions that may increase the risk of complications during or after surgery.

 

It is important to thoroughly discuss all options with a bariatric surgeon and carefully consider the potential risks and benefits of the procedure before deciding on a treatment. 

 

How Is Ileal Interposition Procedure Performed?

 

Ileal Interposition (II) procedure is performed under general anesthesia and typically involves the following steps:

 

  • Creation of a Gastric Pouch: The first step of the procedure involves creating a small gastric pouch to limit the amount of food that can be consumed. This is typically done using a laparoscopic technique, in which small incisions are made in the abdomen, and a scope and instruments are used to perform the procedure.
  • Rerouting of the Small Intestine: Next, the surgeon will isolate a portion of the small intestine and reroute it to the lower portion of the intestine. This bypasses a portion of the small intestine that is responsible for absorbing calories, reducing the number of calories absorbed by the body.
  • Reattachment of the Small Intestine: The rerouted portion of the small intestine is then reattached to the lower portion of the intestine. This allows food to continue to move through the digestive system, but the bypassed portion of the intestine no longer absorbs calories.

 

It is important to note that II surgery is a complex procedure and carries a higher risk of complications compared to other bariatric procedures, such as a gastric sleeve or gastric bypass. The success of the procedure depends on the patient's commitment to a healthy diet and exercise regimen after the surgery, as well as regular follow-up appointments with a doctor to monitor progress and make any necessary adjustments.

 

How is the Ileal Interposition Recovery Cycle?

 

The recovery cycle for ileal interposition surgery can vary depending on several factors, including the type of procedure, the patient's general health status, and the patient's willingness to follow postoperative instructions. In general, patients experience a specific timeline in the recovery process.

 

  • Hospital Stay: Most patients undergo ileal interposition surgery as an outpatient procedure or may require an overnight stay.
  • Pain Management: Pain is managed with a combination of over-the-counter and prescription pain medications.
  • Diet: After Surgery, patients typically follow a liquid diet for several days and gradually progress to solid foods as tolerated.
  • Activity Restrictions: Physical activity should be limited during the first few days following surgery. Light exercise and physical therapy may be recommended to aid in recovery.
  • Follow-up Appointments: Follow-up appointments with the surgeon will be scheduled to monitor the healing process and address any concerns.

 

The recovery cycle may differ from person to person. It is important to remember that some patients may experience complications that may prolong their recovery. It is essential to follow the surgeon's instructions and attend all follow-up appointments to ensure a smooth and successful recovery.
