Laparoscopic Heller Myotomy and Roux-en-Y Gastric Bypass as Treatment for Patients with Achalasia and Morbid Obesity: Outcomes in a Short Series of Patients

Résumé fourni par la source

Background: The association between morbid obesity and esophageal achalasia is very infrequent. However, over the last decade, these cases started to increase because of the disturbing rise of morbid obesity worldwide. Heller myotomy (HM) and laparoscopic fundoplication represent the best treatment option for esophageal achalasia. However, in morbidly obese patients with achalasia, the best treatment option is not established. We present laparoscopic HM and Roux-en-Y gastric bypass (RYGB) as an alternative treatment for morbidly obese patients with achalasia. Materials and Methods: We analyzed the course of patients with achalasia and morbid obesity in our institution undergoing a laparoscopic HM and RYGB, with at least 1 year of follow-up. Symptoms questionnaire, body mass index (BMI), and minuted esophagogram before and after treatment were performed in all patients. Results: Seven patients underwent laparoscopic HM and RYGB. All patients had dysphagia. The mean BMI before the onset of symptoms was 42 kg/m2 (range 40 to 50). In 5 patients, preoperative contrast esophagram showed mild or marked dilated esophagus, and in 2, one esophageal curve and severe dilation. Manometry confirmed the diagnosis. At a mean follow-up of 38 months (range 14–69), all patients reported a marked improvement in dysphagia, with median overall satisfaction rating of 10 (range 9–10), and no symptom of gastroesophageal reflux disease (GERD). The mean percentage excess weight loss (%EWL) was 77.1% (range 70.1–98.1) and the mean BMI was 25.7 kg/m2 (range 23–31). Conclusion: HM and RYGB are an excellent treatment for morbidly obese patients with achalasia. All patients reported a marked improvement of their dysphagia and no symptoms of GERD. The %EWL and BMI descent was very good and maintained through time, showing also an excellent control for morbid obesity.
