What are differences between gastric sleeve and gastric bypass surgery?
Patients who have severe abdominal adhesions from a prior operation benefit from the gastric sleeve procedure. Patients who smoke, use aspirin, or have a history of ulcers may also benefit from having a sleeve gastrectomy.
Patients with severe acid reflux (GERD) and a slow metabolism benefit more from gastric bypass. Gastric bypass is the best option for patients who have previously undergone Nissen fundoplication anti-reflux surgery, in which the stomach was wrapped around the esophageal valve. RNY bypass is preferable for people who need a lot of insulin.
Gastric bypass offers somewhat higher predicted excess weight loss than gastric sleeve and is therefore more suited to treating obesity-related health issues. This is the key distinction between these two procedures. On the other hand, compared to a sleeve gastrectomy, the RNY gastric bypass has greater rates of hazards and more complications.
Because a portion of the intestines is not rerouted or bypassed during a gastric sleeve procedure, it is less invasive than a gastric bypass. The body is unable to absorb vital nutrients and minerals as a result of malabsorption. As a result, it's critical to continue taking vitamins and dietary supplements following gastric bypass.
In gastric bypass, there is a chance to expand the new stomach (stoma), although this is less likely with a gastric sleeve because the pyloric valve is preserved. Patients who have had sleeve surgery have a wide range of viable options for a potential future revision procedure, whereas RNY patients have fewer options.
How does gastric sleeve work?
The new stomach retains around 85% less food (and calories) after a sleeve gastrectomy, so the patient feels satisfied more quickly and for longer.
- Gastric sleeve surgery is a restrictive treatment; a reduced stomach volume implies fewer calories. The gastric sleeve operates through these three methods, i.e., the patient learns to exercise portion management because they are unable to eat a large meal at once.
- The majority of the hunger-inducing hormones that are found in the upper stomach are eliminated. Much less of the gut hormones (Ghrelin) that affect appetite are secreted by the new stomach.
- After gastric surgery, the body regains its sensitivity to leptin levels in the blood flow. Satiety and a sense of fullness are caused by the leptin hormone.
The new, smaller pouch has a similar impact on malabsorption to gastric bypass in that it speeds up stomach emptying and reduces the amount of time food has to be digested.
