Indications for total esophagogastric dissociation in children with gastroesophageal reflux disease.

Abstract
Total esophagogastric dissociation (TED) is used to treat gastroesophageal reflux (GER) after failed fundoplication in neurologically impaired patients. It is now performed for some otherwise healthy patients with severe GER. In this procedure, the gastrointestinal tract is reconstructed in a non-physiological way with a Roux-en-Y esophagojejunal anastomosis and jejuno-jejunostomy. Although TED eliminates almost all GER, some patients experience late complications. In this review, we investigated the long-term outcomes after TED to determine the best indications. In total, 147 neurologically impaired patients and 28 neurologically normal patients were identified. The total rate of complications requiring re-operation was 17.2% in neurologically impaired patients and 32.1% in normal patients, both higher than the rates associated with fundoplication. Although most authors added pyloroplasty when there was a concern of gastric emptying, this sometimes caused bile reflux. Nutritional and metabolic complications, including dumping syndrome and chronic digestive malabsorption, were also reported to occur after TED. TED is an option for the treatment of neurologically impaired patients with recurrent GER after fundoplication or who are at a high risk of recurrence of GER with fundoplication. However, neurologically normal patients who have the ability to obtain nutrition orally should consider options other than TED, as postoperative complications are frequent.

Metabolic and nutritional complications of bariatric surgery : a review.
Mesureur, L, Arvanitakis, M
Acta gastro-enterologica Belgica. 2017;(4):515-525
Abstract
Bariatric surgery is considered as the only effective durable weight-loss therapy and may be curative for obesity-related comorbidities such as diabetes. Nevertheless this surgery is not devoid of potential long-term complications such as dumping syndrome, gastroesophageal reflux disease and nutrient deficiencies. For this reason, preoperative nutritional assessment and rigorous postoperative follow-up with administration of multi-vitamins supplements and assessment of serum levels is recommended for each patient who is undergoing a bariatric surgery. The aim of this review is to identify and treat the metabolic and nutritional complications of bariatric surgery.

Complications of bariatric surgery: dumping syndrome, reflux and vitamin deficiencies.
Tack, J, Deloose, E
Best practice & research. Clinical gastroenterology. 2014;(4):741-9
Abstract
Bariatric surgical procedure are increasingly and successfully applied in the treatment of morbid obesity. Nevertheless, these procedures are not devoid of potential long-term complications. Dumping syndrome may occur after procedures involving at least partial gastric resection or bypass, including Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy. Diagnosis is based on clinical alertness and glucose tolerance testing. Treatment may involve dietary measures, acarbose and somatostatin analogues, or surgical reintervention for refractory cases. Gastro-esophageal reflux disease (GERD) can be aggravated by vertical banded gastroplasty and sleeve gastrectomy procedures, but pre-existing GERD may improve after RYGB and with adjustable gastric banding. Nutrient deficiencies constitute the most important long-term complications of bariatric interventions, as they may lead to haematological, metabolic and especially neurological disorders which are not always reversible. Malabsorptive procedures, poor postoperative nutrient intake, recurrent vomiting and poor compliance with vitamin supplement intake and regular follow-up are important risk factors. Preoperative nutritional assessment and rigourous postoperative follow-up plan with administration of multi-vitamin supplements and assessment of serum levels is recommended in all patients.

Tolerance of probiotics and prebiotics.
Marteau, P, Seksik, P
Journal of clinical gastroenterology. 2004;(6 Suppl):S67-9
Abstract
The clinical efficacy of probiotics and prebiotics has been proved in several clinical settings. The authors review their proved or potential side effects. Probiotics as living microorganisms may theoretically be responsible for 4 types of side effects in susceptible individuals: infections, deleterious metabolic activities, excessive immune stimulation, and gene transfer. Very few cases of infection have been observed. These occurred mainly in very sick patients who received probiotic drugs because of severe medical conditions. Prebiotics exert an osmotic effect in the intestinal lumen and are fermented in the colon. They may induce gaseousness and bloating. Abdominal pain and diarrhea only occur with large doses. An increase in gastroesophageal reflux has recently been associated with large daily doses. Tolerance depends on the dose and individual sensitivity factors (probably the presence of irritable bowel syndrome or gastroesophageal reflux), and may be an adaptation to chronic consumption.
