Sleeve Gastrectomy / Gastric Sleeve, Raleigh, North Carolina
The Sleeve Gastrectomy is a surgery performed only on the stomach and does not involve any surgery on intestines (which would make it malabsorptive).
Sleeve Gastrectomy has also been called Partial Gastrectomy and Vertical Sleeve Gastrectomy and Gastric Sleeve. It basically consists of making a stomach that looks like a pouch into a long tube; therefore the name “sleeve.” The Sleeve Gastrectomy removes two thirds of the stomach, which provides for quicker satiety (sense of fullness) and decreased appetite.
The smaller stomach pouch restricts food intake by allowing only a small amount of food to be eaten at one time. After the separation of the stomach into a smaller tube, the remainder of the stomach is removed. The valve at the outlet of the stomach remains; this provides for the normal process of stomach emptying to continue which allows for the feeling of fullness. If you eat too quickly, take large bites of food, drink fluids with meals/snacks, eat dry, tough, or sticky foods, vomiting or discomfort can occur.
- The sleeve is created with a surgical stapler along the inside curve of the stomach.
- After the new stomach is created the remaining stomach is removed.
- The valve at the outlet of the stomach remains, which provides for the normal process of stomach-emptying to continue, which allows for the feeling of fullness.
- Internal incisions are typically closed with absorbable sutures and will not need to be removed. External incisions can be closed with sutures, steri-strips, or staples.
Sleeve Gastrectomy Surgery and Potential Side Effects
The sleeve gastrectomy is typically performed in less than an hour. The majority of the outer portion of the stomach is removed leaving a small tubular stomach behind (see photo). Often, most patients feel less hungry and are less interested in carbohydrates, and patients lose weight despite usually not feeling hungry!
Common side effects early on include nausea and feeling full. If you eat too quickly or too much you may throw up, which is defeating the purpose of the surgery. Average meal should be one cup of food or less over the course of 30 minutes five times daily spaced 3-4 hours apart.
Average weight loss depends on several factors, the most important being the compliance of the patient in regards to their diet. Other factors include the weight a patient started at, incorporating exercise and being more active, avoiding calorie-laden beverages, and complying with medical therapy for other ailments. Average weight loss is between 50-70% of your excess weight.
