Gastrectomía en manga
Sleeve gastrectomy (SG), also known as gastric sleeve surgery, bariatric sleeve surgery or vertical gastrectomy, involves shrinking the size of the stomach to help an individual lose weight by limiting their calorie intake. During a sleeve gastrectomy around 80% of the lower stomach is removed creating a long, tubular structure, which will limit food intake.
A sleeve gastrectomy can be performed as a minimally invasive laparoscopy, which involves making small incisions through which surgical tools and a specialized camera will be inserted. In rare cases, sleeve gastrectomy may be done as an open surgery, where a large abdominal incision must be made. In both cases, the patient receives general anesthesia, so they stay asleep throughout the surgery.
Recognized and Approved for Weight Loss
Sleeve gastrectomy is recognized by the American Society for Metabolic and Bariatric Surgery (ASMBS) as an approved procedure for weight loss.
Sleeve gastrectomy surgery helps people lose weight and reduce their risk of developing life-threatening health problems associated with excessive body fat, such as cancer, diabetes and heart disease. Bariatric surgery is not a cure for any of these conditions, but it can help reduce obesity-related health complications.
The mechanisms of weight loss and improvement in co-morbidities seen after SG might be related to:
- Gastric restriction - restricting the amount of food you can eat
- Hormonal changes related to gastric resection, such as the GLP-1 hormone which reduces appetite and regulates glucose metabolism
- Gastric emptying, with food passing through the stomach faster
In comparison to gastric bypass, sleeve gastrectomy, which primarily restricts food intake rather than altering the digestive pathway, does not predispose individuals to marginal ulcers, vitamin deficiencies, dumping syndrome or malabsorption. Endoscopy can still be used as a diagnostic technique, as the remaining stomach and first portion of the intestine are still accessible.
How Is Sleeve Gastrectomy Performed?
A laparoscopic sleeve gastrectomy is usually performed in this manner:
- The surgeon creates several small incisions in the abdominal area to insert surgical tools and a camera.
- A measuring device known as a bougie (specialized tube) is placed into the stomach to determine the appropriate length of the stomach that should remain. This flexible tube helps the surgeon maintain a consistent size for the newly formed stomach sleeve.
- A surgical stapler will be used to divide the stomach into two and seal it in between.
- The surgeon removes the larger portion of the stomach and closes the incision.
- The surgical instruments are removed. The incisions are stitched closed.
After surgery, patients are brought to the recovery area, where they are closely monitored. The doctor will provide them with post-operative care that includes instructions on managing pain, watching out for complications and consuming foods. Patients will also need to attend follow-up appointments with their healthcare provider to monitor their progress. Nutritional counseling and lifestyle adjustments may also be part of postoperative care.

La cirugía de pérdida de peso se recomienda para personas con un índice de masa corporal (IMC) igual o superior a 35, independientemente de la presencia, ausencia o gravedad de las comorbilidades. La banda gástrica ajustable laparoscópica con banda gástrica® también está aprobada por la FDA para la cirugía de pérdida de peso en personas con un IMC de 30 a 35 que tienen al menos una afección relacionada con la obesidad. La cirugía para bajar de peso se considera segura, pero como muchos tipos de cirugía, tiene riesgos. Consulte con su médico sobre los riesgos y beneficios de la cirugía de pérdida de peso. Estos testimonios reflejan los resultados alcanzados por estos pacientes. Como cada caso debe evaluarse y manejarse de forma independiente, la pérdida de peso real variará.
