SINGLE ANASTOMOSIS STOMACH–ILEAL BYPASS WITH SLEEVE GASTRECTOMY (SASI-S) PERTH

SASI-S (Single Anastomosis Stomach–Ileal Bypass with Sleeve Gastrectomy) is a modified and safer version of SADI-S (Single Anastomosis Duodenal–Ileal Bypass with Sleeve Gastrectomy). SASI-S combines the benefits of sleeve gastrectomy and intestinal bypass.

Sleeve gastrectomy removes 75% of the stomach resulting in a reduced capacity to eat and a reduced level of ghrelin, the hormone which causes hunger. Intestinal bypass involves joining the bottom part of the stomach (antrum) to the lower part of the small bowel (ileum).

This results in food bypassing part of the small intestine which causes a reduction in the absorption of fats, sugar and calories that are consumed. The amount of small bowel bypassed can be varied depending on the desired weight loss.

Advantages of the SASI-S procedure

Studies show SASI-S can provide greater weight loss than either a standard sleeve gastrectomy or gastric bypass. Some other advantages of SASI-S include:

• Combines benefits of sleeve and bypass
• Less risk of a leak from staple line as there are fewer staple lines than SADI-S
• Less risk of staple line leak from the sleeve as the muscle at the outlet of the stomach (pylorus) is bypassed
• Less risk of nutritional deficiencies as duodenum not excluded
• Access to bile duct to remove gallstones is intact (ERCP possible)
• Less risk of internal hernia

Disadvantages of the SASI-S procedure

• Increased risk of bile reflux into the stomach
• Weight loss may be less than SADI-S

How does Dr Kevin Dolan perform the SASI-S procedure?

The SASI-S procedure is a two-step process:

1. Create sleeve gastrectomy.
2. Join the bottom part of the stomach (antrum) to the distal part of the small bowel (ileum). The length of the bypass can be varied depending on the desired weight loss.

Post-Surgical Care

Following your surgery, you will spend two days in the hospital and will be administered pain-controlling medications to keep you comfortable. For the first two weeks following your surgery, you will be kept on a liquid diet. Your surgeon and dietician will give you a specific diet plan and instructions to follow after this. It is important to drink plenty of fluids throughout the day to avoid dehydration.

What are the Costs and Funding Options for SASI-S Surgery?

Costs will vary from $0 to $6000 out of pocket expenses depending on the complexity of the surgery and the previous surgery weight. Dr Dolan will discuss costs at your first consultation.

Medicare rebates are available for this procedure and our surgery offers payment plans for patients.
