Laparoscopic adjustable gastric banding outcomes in patients with gastroesophageal reflux disease or hiatal hernia

Esophageal Squamous Cell Carcinoma After Adjustable Gastric Banding

The prevalence of morbid obesity has been increasing worldwide. Therefore, multiple laparoscopic adjustable gastric bandings (LAGBs) have been placed in Belgium in the nineties. The procedure was considered as minimal invasive with low morbidity rates. However, some publication cases suggest a possible association between LAGB and the onset of an esophageal cancer. We present a case of a 49-year-old female who consulted for dysphagia, epigastric pain, and anorexia 17 years after LAGB. An esophageal squamous cell carcinoma was diagnosed in the distal esophagus, close to the lap band. The diagnostic value of the performed contrast swallow study seemed limited. We suggest that a routinely gastroscopic evaluation in the long-term follow-up after LAGB should be strived for in patients presenting with late-onset dysphagia.

Ten years of follow-up of bilio-intestinal bypass: is malabsorption necessary for long-term metabolic results?

BACKGROUND

Bilio-intestinal bypass (BIBP) is an uncommon bariatric procedure. In 1999, a prospective trial was started at our institution to evaluate the effectiveness of BIBP. Trial was interrupted in 2006 due to high rate of complications. The aim of the present paper was to retrospectively review 10-year outcomes of BIBP.

METHODS

Retrospective review of bariatric database was performed to find patients that had undergone BIBP from 1999 to 2006. Data collected were as follows: age, gender, body weight, body mass index (BMI), percentage of excess weight loss (%EWL), remission from weight-related diseases, complications, and deaths at 1,3, 5, 7, and 10 years. Quality of life was evaluated using "BAROS" questionnaire.

RESULTS

From May 1999 to September 2006, 86 patients underwent BIBP. The mean age was 34.9 ± 22.4 years, and the initial weight and BMI were 141.2 ± 40.4 kg and 49.8 ± 15.5 kg/m², respectively. After 10 years, the mean %EWL and BMI were 72.6 ± 18.7 and 31.2 ± 5.6 kg/m². Almost all patients had diarrhea after surgery. Bloating syndrome occurred in 24% of patients, 48% had nephrolithiasis, and 20.9% had cholelithiasis. Remission from diabetes and hypertension was obtained in 75% and 80% of patients. Mortality was 3.2% and reoperation rate was 14.5%.

CONCLUSIONS

Malabsorption plays a determinant role to obtain a long-lasting treatment for obese patients. However, BIBP is not recommendable due to high rate of complications and metabolic disorders.

Operative Treatments for Reflux After Bariatric Surgery: Current and Emerging Management Options

Gastroesophageal reflux disease (GERD) is a common disorder that has a well-established connection with obesity. To ameliorate the morbidity associated with obesity, bariatric procedures have become an established pathway to accomplish sustained weight loss. In some procedures, such as with the Roux-en-Y gastric bypass surgery, weight loss is also accompanied by the resolution of GERD symptoms. However, other popular bariatric surgeries, such as the sleeve gastrectomy, have a controversial impact on their effect on reflux. Consequently, increased attention has been given to the development of strategies for the management of de novo or recurrent reflux after bariatric surgery. This article aims to discuss medical and surgical strategies for reflux after bariatric surgery, and their outcomes.

Impact of obesity treatment on gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD) is a frequently encountered disorder. Obesity is an important risk factor for GERD, and there are several pathophysiologic mechanisms linking the two conditions. For obese patients with GERD, much of the treatment effort is focused on weight loss and its consistent benefit to symptoms, while there is a relative lack of evidence regarding outcomes after novel or even standard medical therapy is offered to this population. Physicians are hesitant to recommend operative anti-reflux therapy to obese patients due to the potentially higher risks and decreased efficacy, and these patients instead are often considered for bariatric surgery. Bariatric surgical approaches are broadening, and each technique has emerging evidence regarding its effect on both the risk and outcome of GERD. Furthermore, combined anti-reflux and bariatric options are now being offered to obese patients with GERD. However, currently Roux-en-Y gastric bypass remains the most effective surgical treatment option in this population, due to its consistent benefits in both weight loss and GERD itself. This article aims to review the impact of both conservative and aggressive approaches of obesity treatment on GERD.

Gastroesophageal reflux disease in the obese: Pathophysiology and treatment

Obesity is a condition that has increased all over the world in the last 3 decades. Overweight and gastroesophageal reflux disease (GERD) are related. GERD may have different causative factors in the obese compared with lean individuals. This review focuses on the proper treatment for GERD in the obese based on its pathophysiology. Increased abdominal pressure may play a more significant role in obese subjects with GERD than the defective esophagogastric barrier usually found in nonobese individuals. A fundoplication may be used to treat GERD in these individuals; however, outcomes may be not as good as in nonobese patients and it does not act on the pathophysiology of the disease. All bariatric techniques may ameliorate GERD symptoms owing to a decrease in abdominal pressure secondary to weight loss. However, some operations may lead to a disruption of natural anatomic antireflux mechanisms or even lead to slow gastric emptying and/or esophageal clearance and thus be a refluxogenic procedure. Roux-en-Y gastric bypass decreases both acid and bile reflux from the stomach into the esophagus. On the other hand, gastric banding is a refluxogenic operation, and sleeve gastrectomy may show different outcomes based on the anatomy of the gastric tube.
