    Abstract:
    In industrialized countries, surgical gastroplasty is performed more and more frequently in patients with morbid obesity. The aims of this prospective study were to determine the incidence of upper gastrointestinal lesions in obese patients and to assess the place of digestive endoscopy in symptomatic patients after gastroplasty. A consecutive group of 159 obese patients were studied before and after vertical banded gastroplasty. In the preoperative evaluation, reflux esophagitis and gastroduodenal lesions were endoscopically observed in 31% and 37% of the patients, respectively. Interestingly, the majority of the obese patients with upper gastrointestinal lesions were asymptomatic. In the postoperative follow-up period, 55 of the 159 patients complained of upper gastrointestinal symptoms such as vomiting (72%), esophageal reflux (17%), and epigastric pain (3%). Stenosis of the outlet of the gastric pouch was described in 40 of the 55 symptomatic patients. Esophagitis was observed in 60% of these patients. Endoscopic dilation using Savary bougies or TTS balloon was successfully performed in all the patients with symptomatic stenosis of the gastric outlet. Food impaction was endoscopically removed in four patients. Thus, we recommend performing an upper gastrointestinal endoscopy in obese patients who are candidates for surgical gastroplasty because of the high incidence of upper gastrointestinal peptic lesions. Endoscopy is also helpful in patients with digestive disorders occurring after gastroplasty in order to define and to treat the lesions.
