Obesity continues to plague our society in epidemic proportions. Surgery for morbid obesity is considered by many as the most effective therapy for this complex disorder. Today, multiple surgical procedures for the treatment of obesity are available. As with most procedures, there are benefits and risks associated with open and laparoscopic gastric bypass surgery, as well as with laparoscopic adjustable gastric banding and partial biliopancreatic bypass with a duodenal switch. The risks and complications associated with bariatric surgery may be serious and in some cases life threatening. However, surgery for obesity has shown remarkable results in helping patients to achieve significant long-term weight control. In addition, it is associated with improvement and often resolution of co-morbid conditions, including type 2 diabetes mellitus, systemic hypertension, obesity hypoventilation, sleep apnea, venous stasis disease, pseudotumor cerebri, polycystic ovary syndrome, complications of pregnancy and delivery, gastroesophageal reflux disease, stress urinary incontinence, degenerative joint disease, and non-alcoholic steatohepatitis.

Regression of Barrett's esophagus may occur after effective anti-reflux surgery. Roux-en-Y gastric bypass (RYGBP) is an effective operation to treat morbid obesity. In addition, it provides complete relief of gastroesophageal reflux disease (GERD). Regression of Barrett's has not been reported after RYGBP. We performed a laparoscopic Roux-en-Y gastric bypass on a patient with GERD and Barrett's esophagus. At 1 year after the RYGBP, an upper endoscopy was performed as routine surveillance for the patient's Barrett's esophagus; endoscopic and histologic evaluation demonstrated complete regression of the Barrett's esophagus. The patient lost one-third of her preoperative weight and had resolution of her reflux symptoms. RYGBP limits the amount of acid reflux and completely diverts bile away from the esophagus. This may lead to the regression of Barrett's esophagus.

Weight loss is a frequent finding in achalasia because of the difficulty in swallowing. Although manometric findings compatible with achalasia have been found in morbidly obese patients, all of them were asymptomatic. The authors report a case of symptomatic achalasia and morbid obesity in a 38-year-old woman. A mental disorder become manifested after the patient was submitted to an esophageal myotomy and fundoplication. With weight gain, postoperative gastroesophageal reflux developed. Drawbacks of further operative procedures in such a patient are discussed.

During the past decade, laparoscopic adjustable gastric banding has become the most popular surgical procedure in treating morbid obesity. On the other hand, significant drawbacks such as inadequate long-term weight loss, a high prevalence of reoperations, and frequent postoperative symptoms have been reported in the literature. This analysis summarizes our Department's experience with this operation. Thirty-one patients (27 women and 4 men) with a mean body mass index of 46.5 kg/m(2) (range, 38.3-59.8 kg/m(2)) were operated upon laparoscopically between September 1997 and January 2003. The preoperative work-up of all patients included a psychological evaluation. Mean follow-up was 59.3 months (range, 19-84 months). Sixteen patients had esophageal pH-metry and 18 patients had upper gastrointestinal endoscopy preoperatively and postoperatively. Data were collected prospectively during the outpatient visits. Mean preoperative excess weight was 65.6 kg (range, 37.4-96.1 kg). Mean excess weight loss after 12, 24, 36, 48, 60, 72, and 84 months was 40.3%, 50.5%, 51.9%, 48.9%, 46.2%, 51.8%, and 30.2%, respectively. In total, six patients (19.4%) had an abdominal reoperation, including four patients (12.9%) for band removal. Upper gastrointestinal endoscopy was performed in 18 patients after 30.1 months (range, 5-67 months), showing a high prevalence of esophagitis (30.0%; grade 1: n=3, grade 2: n=3). Conversely, postoperative esophageal pH-metry performed in 16 patients was pathologic in 43.8%. Laparoscopic adjustable gastric banding produces significant weight loss even after long-term follow-up. However, the reoperation rate is high and postoperative symptoms are frequent. The high incidence of gastroesophageal reflux and esophagitis remains a matter of concern.

Flexible endoscopy has evolved from a diagnostic tool practiced predominantly by gastroenterologists to a minimally invasive surgical tool. Therapeutic endoluminal procedures have become the standard of care for many gastric, biliary, pancreatic and colonic maladies. New technologies are under investigation for endoscopic treatment of gastroesophageal reflux, morbid obesity, and ablation of premalignant tissue. In the future flexible endoscopes may play a role in "natural orifice" surgery, performing operations through the mouth or rectum without the need for external incisions.

Obesity is epidemic in the modern world. It is becoming increasingly clear that obesity is a major cause of cardiovascular disease, diabetes, and renal disease, as well as a host of other comorbidities. There are at present no generally effective long-term medical therapies for obesity. Surgical therapy for morbid obesity is not only effective in producing long-term weight loss but is also effective in ameliorating or resolving several of the most significant complications of obesity, including diabetes, hypertension, dyslipidemia, sleep apnea, gastroesophageal reflux disease, degenerative joint disease, venous stasis, pseudotumor cerebri, nonalcoholic steatohepatitis, urinary incontinence, fertility problems, and others. The degree of benefit and the rates of morbidity and mortality of the various surgical procedures vary according to the procedure.

Post-surgical gastroparesis (PSG) is recognized as a consequence of vagal nerve injury following upper abdominal surgery. It has been well documented following vagotomy for peptic ulcer surgery. With the increasing role of surgical treatment in the management of GERD and morbid obesity, PSG is now being diagnosed after fundoplication and bariatric surgery. PSG has also been reported after heart and lung transplantation, possibly due to opportunistic viral infection or motor-inhibitory effects of the immunosuppressive drugs, in addition to vagal nerve injury. Initial postoperative management of PSG should be conservative as many symptoms following abdominal surgery resolve with time. This occurs possibly because the enteric nervous system is able to adapt to the loss of vagal input or vagal reinnervation occurs. Persistent symptoms are difficult to manage and require a multidisciplinary team approach. Gastric electrical stimulation has shown promise in small series.

Bariatric surgery has considerably developed during the last 20 years in Belgium. The increase of prevalence of the morbid obesity and the development of multiple surgical procedures widened the spectrum of treatment. If a rigorous selection and a multidisciplinary approach of the patients are inescapable, the various decision-making algorithms plunge the practitioner into a certain confusion. The purpose of this paper is to clarify the advantages and the inconveniences of the different surgical treatments in light of the evolution of the principles and the objective results of the literature. Among the techniques proven and validated in the long run, one can mention the Silastic Ring Vertical Gastroplasty according to Mac Lean by minilaparotomy, the laparoscopic adjustable ring and the more recent gastric by pass. The evaluation of laparoscopic sleeve gastrectomy, and of duodenal switch is on course. The bilio-pancreatic by-pass according to Scopinaro remains strongly controversed. A meta-analysis of the literature confirms the success of the gastric bypass. Regarding to the long term follow-up, the adjustable gastric banding deceives. The sleeve gastrectomy should be analyzed in the long term. The preliminary results of a epidemiologic and financial study within a private hospital of Brussels reveals that the cost effective ratio is in favor the Silastic Ring Vertical Gastroplasty and the laparoscopic adjustable banding, as well in terms of public health support than the charge for the private insurance and the patient. The projection beyond 5 years reverses the tendency to plead in favor of the gastric by-pass. First with the hit-parade of comfort, food diversification, tolerance, gastro-esophageal reflux, and undoubtedly of the rate of recurrence, it supplants the others techniques for sweet eaters. The volume eaters can profit from a sleeve gastrectomy which undoubtedly supplants the Silastic Ring Vertical Gastroplasty responsible for late annular stenoses and reccurences.

Obesity has been implicated as an important risk factor for the development of gastroesophageal reflux disease (GERD). A variety of physiological abnormalities have been described which likely contribute to the association of GERD and obesity. These abnormalities involve the oesophageal body, lower oesophageal sphincter and stomach. For obese patients with GERD, weight loss in conjunction with anti-secretory medications is first-line therapy. For those with severe obesity who fail medical weight loss treatment, bariatric surgery has been shown to be beneficial. On balance, Roux-en-Y gastric bypass is probably the most efficacious surgery for patients with morbid obesity suffering from concomitant GERD.

Gastro-oesophageal reflux disease (GORD) and morbid obesity are entities with increasing prevalence. New clinical strategies are cornerstones for their management. The aim of this study was to assess the prevalence of heartburn during sleep (HDS) and whether this symptom predicts the presence of objective GORD parameters and increased heartburn perception in morbidly obese patients. Ninety-one consecutive morbidly obese patients underwent clinical evaluation, upper gastrointestinal endoscopy and oesophageal pH monitoring. HDS was characterized when patients replied positively to the question, 'Does heartburn wake you from sleep?'. A General Score for Heartburn (GSH) ranging between 0 and 5 was assessed with the question 'How bad is your heartburn?'. HDS was reported by 33 patients (36%). More patients with HDS had abnormal acid contact time or reflux oesophagitis than patients without HDS (94%vs 57%, P < 0.001). HDS had a positive predictive value of 94% (0.95 CI 82-98), sensitivity of 48% (0.95 CI 37-60%) and specificity of 93% (0.95 CI 77-98%) for detection of GORD. A higher proportion of patients with HDS perceived heartburn preceded by acid reflux in diurnal (39%vs 9%; P < 0.001) periods during pH-metry. HDS patients showed higher GSH (2.4 +/- 0.5 vs 1.7 +/- 0.4; P < 0.0001) compared with patients who denied HDS but reported diurnal heartburn. HDS occurs in a significant minority of patients with morbid obesity and has high positive predictive value for GORD. Symptomatic reflux during the sleep seems to be a marker of increased heartburn perception in this population.
