Laparoscopic Surgery for Morbid Obesity

The morbid obesity epidemic continues to spread throughout industrialized nations. It is a condition with a heterogeneous etiology, including genetic, psychosocial, and environmental factors. Prevention methods have currently been unable to halt the further spread of this disease. Obesity has been linked to increased healthcare costs, common physiologic derangements, reduced quality of life, and increased overall mortality. More than one third of adults and almost 17% of children in the United States are obese.

Medical therapy that can cause sustained significant weight loss may be years away. Bariatric surgery, when combined with a multidisciplinary team, continues to be the only proven method to achieve sustained weight loss in most patients. Bariatric procedures modify gastrointestinal anatomy and, in some cases, enteric hormone release to reduce caloric intake, reduce absorption, and alter metabolism to achieve weight loss. Currently, the three most common bariatric operations in the United States are Roux-en-Y gastric bypass, adjustable gastric band, and the vertical sleeve gastrectomy.

  2. […] While it is true that most sleeve-related GERD will be effectively treated with a conversion to Roux-en-Y gastric bypass, not every patient with GERD after reflux will require a bypass or would agree to have one. First key step in addressing the patient is to evaluate whether the patient was selected appropriately to have a sleeve and second is to determine the exact sleeve anatomy; are there anatomical factors that will make it more likely for this patient to experience reflux; is there dilated fundus? Is there a kink or stricture in the sleeve or is it an anatomically appropriate operation? We should pay important attention to the weight loss the patient has experienced with the sleeve. Patients who do not have adequate weight loss and have GERD symptoms should not undergo other therapies and should probably undergo a bypass; however it is our unpublished experience that patients with the association of poor weight loss after sleeve and difficult to treat GERD will correct their GERD after conversion, but their weight loss results are still marginal even with a well-constructed bypass.
