Duodenal Switch Surgery in Argentina

The Duodenal Switch Surgery is associated with the best results in terms of weight loss and is applied to severely obese patients.

This method includes the two ways to help patients lose weight, since it combines a reduction of the stomach size as in the gastric sleeve procedure with a rerouting of a lengthy portion of the small intestine.

By means of a suture, the stomach is divided vertically, and nearly 80% is removed. The intestine is then divided at the level of the duodenum and approximately 4 meters ahead.

The stomach is then connected to the distal part of the intestine allowing food to pass, and the remaining portion of the stomach is connected to the intestine where bile and digestive juices mix with food.

In this way, the procedure restricts food intake, and a lengthy portion of the small intestine is bypassed reducing the absorption process, generating a new food circulation.

Initially, the amount of food consumed is not enough to meet energy needs, forcing the body to use stored fat. However, as time goes by, an adaptation phenomenon that allows the patient to maintain body weight at the same pace of eating will occur.

Technique: Minimally invasive, video assisted laparoscopic procedure.
Length: 2 to 3 hours depending on the state of the patient.
Anesthesia: General Anesthesia.
Hospitalization: from 4 to 5 days.

After the surgery

In the recovery room, you can expect to have some discomfort and feel the effects of the surgery (this can last for several days). Some medicine for this may be prescribed to help control pain. Or infusion pump may be used which provides a local anesthetic directly to the surgical site to control pain without the side effects of narcotics.

The changes made to your gastrointestinal tract will require permanent changes in your eating habits that must be followed for successful weight loss. What is vital is that you follow the physician guidelines'. The following are some of the usually accepted dietary guidelines:

* When you start the consumption of solid food, chew your food thoroughly and eat very slowly. It is important to wait a few minutes after swallowing before putting the next bite of food in your mouth.

* Don't drink fluids while eating. They will make you feel full before you have eaten enough food.

* Don't eat desserts and other items with sugar if they have more than 3 to 5 grams per serving size.

* Avoid carbonated drinks, high-calorie nutritional supplements, foods high in fat, milk shakes, and foods that have no nutritional value.

* Avoid alcohol.

* Reduce snacking between meals.

Returning to Normal Routine

After the Duodenal Switch Surgery, the surgeon requires you to get up and move around. You are asked to walk or stand at the bedside the night of surgery and take several walks the next day. After leaving the hospital, you may be able to concern on all your personal needs, but you will need help with shopping and lifting, and with transportation.

Drive is an activity that usually takes from 7 to 14 days to resume, as is not appropriate while under medications.

Depending on your physical condition, the nature of the activity, and the type of bariatric surgery you had, the surgeon suggests you the rhythm of returning to routine. Many patients return to normal levels of activity within six weeks of surgery.
It is strongly advised that women of childbearing age use the most effective forms of birth control during the first 16 to 24 months after bariatric surgery.

Bariatric Surgery Alternatives to Duodenal Switch:

  • Lap Band: Gastric band surgery is based on the placement of a prosthetic silicone ring around the upper stomach.
  • Gastric Bypass Surgery: the most frequently performed surgery. This method combines the two ways to help patients lose weight, even though the main purpose of gastric bypass surgery is to reduce the volume of the stomach.
  • Gastric Sleeve Surgery: it has recently gained popularity and is associated with excellent results of weight loss. It is a restrictive procedure since approximately only 80% of the stomach is removed.
