General information
The gastric bypass is based on reducing the size of the stomach with sutures (without an incision), to limit food intake. The gastric volume is reduced by about 75%.
The laparoscopic intervention typically lasts around 40 minutes. It begins by freeing the vascular connections from the wider section of the stomach (located at the greater gastric curvature), followed by inward folding of the gastric wall and suturing it.
As in all bariatric operations, there are certain dietary rules that must be followed after gastric bypass surgery. The patient must consume liquid food during the first 2 postoperative weeks, after which different pureed foods can be consumed. After the first postoperative month, the patient can eat solid food again.
Similar to other bariatric surgery procedures, gastric bypass surgery can be performed with considerably lower risks. Its early postoperative complication rates are minimal, ranging from 1% to 9%. No mortality risk associated with this type of intervention has been reported, and the rate of serious complications is less than 1%.
Nausea and vomiting are the most common problems encountered in the early postoperative period, but these can be easily managed and reduced by medication.
Who is it suitable for?
The gastric bypass is the operation addressed to patients who suffer from overweight and obesity of the first degree, being suitable for losing about 25-30 kilograms.
Body weight will be normal at the end of the first year after surgery. Like other bariatric operations, the procedure also has beneficial effects against obesity comorbidities, such as hypertension or diabetes.
Contraindications to this surgical procedure include hiatal hernias and gastroesophageal reflux disease.
