The Roux-en-Y gastric bypass is known as the "gold standard" by which all other bariatric surgeries are measured. It is a precise surgical procedure that restructures the digestive system in a way that simultaneously reduces the amount of food consumed and the absorption of calories.

The procedure completely separates the stomach into a small upper portion (pouch) and a remaining lower portion, then connects the small intestine to the upper pouch in a Y-shaped configuration. This ensures an alteration of the natural food pathway and hormonal changes that promote calorie burning and rapid satiety.

Procedure Steps

The Roux-en-Y bypass requires very high surgical skill — an area where Dr. Abdulrahman Al-Sayigh excels through the following steps:

  1. Complete Stomach Separation: Unlike some other procedures, the stomach is completely separated to create a very small pouch (approximately 30 ml capacity), significantly limiting the amount of food you can consume.
  2. Intestinal Reconnection: The small intestine is cut and its lower end is connected to the new gastric pouch, while the upper end (carrying digestive juices) is reconnected to the side of the intestine at a defined distance, reducing the absorption area.
  3. Laparoscopic Precision: The entire procedure is performed through very small holes in the abdomen, reducing recovery time and ensuring excellent cosmetic results (barely visible scars).
  4. Surgical Safety: The latest generation of medical staplers is used, with dual pressure and leak tests performed to ensure 100% integrity of all surgical connections before leaving the operating room.

Advantages & Results

What makes Roux-en-Y the preferred choice for certain cases:

  • Permanent Solution for Acid Reflux: It is the only procedure that guarantees a near-permanent cure for patients with severe acid reflux and heartburn, as the acid pathway is completely separated from the esophagus.
  • Most Stable Results: Long-term medical studies (over 20 years) confirm that Roux-en-Y provides the best long-term weight maintenance compared to any other procedure.
  • Full Control of Metabolic Diseases: Achieves the highest remission rates from diabetes, high blood pressure, and cholesterol/triglyceride disorders.
  • Goodbye to Sweets: Remarkably helps patients change their eating behavior and avoid sweets through the positive "dumping syndrome" that prevents the body from tolerating high sugar intake.

Pre- and Post-Operative Instructions

Before the Procedure:

  • Perform precise examinations including gastric endoscopy to check the condition of the esophagus and stomach valve before surgery.
  • "Pre-surgery diet" to reduce fat around the liver, giving the surgeon a clearer view and greater safety during the operation.
  • Complete fasting for 8 hours, and stop blood-thinning medications (under physician supervision).

After the Procedure (Tips for Reaching Your Ideal Weight):

  1. Strict Nutrition Protocol: Following the liquid phase (two weeks) then pureed (two weeks) is essential to ensure healing of the precise surgical connections.
  2. Vitamins Are Your Lifelong Companion: Due to reduced absorption, daily vitamins and minerals (for life) are mandatory to ensure bone and blood health and prevent hair loss.
  3. The Art of Eating: Meals must be small (palm-sized) and spread throughout the day, with eating and drinking separated by 30 minutes to avoid nausea or pressure.
  4. Avoid "Dumping": Completely avoid concentrated sugars and sweets, as consuming them may cause sweating or rapid heartbeat (a temporary sensation that helps you stay on your diet).
  5. Lab Follow-Up: Comprehensive blood tests every 3-6 months in the first year are a safety valve to confirm your body is receiving all necessary nutrients.
  6. Movement and Activity: Daily walking from the first week speeds up fat burning and prevents blood clots; avoid vigorous exercise for two months.
