Endoscopic revision of gastrojejunal anastomosis for the treatment of dumping syndrome in patients with Roux-en-Y gastric bypass: a systematic review and meta-analysis

Endoscopic Management of Surgical Complications of Bariatric Surgery

Bariatric surgery, although highly effective, may lead to several surgical complications like ulceration, strictures, leaks, and fistulas. Newer endoscopic tools have emerged as safe and effective therapeutic options for these conditions. This article reviews post-bariatric surgery complications and the role of endoscopy in their management.

Dumping Syndrome: Pragmatic Treatment Options and Experimental Approaches for Improving Clinical Outcomes

Dumping syndrome is a common complication after esophageal, gastric and bariatric surgery and has a significant negative impact on the quality of life of patients. This narrative review describes the clinical syndrome, pathophysiology, diagnosis and reports on standard and pragmatic therapeutical treatment options in order to improve the clinical outcome of patients with dumping syndrome. Dumping syndrome consists of early and late dumping symptoms and can be diagnosed using clinical parameters with the help of the Sigstad's score, questionnaires or by provocative testing. The prevalence of dumping syndrome varies depending on the employed definition of dumping syndrome. Overall, dumping syndrome is more frequent nowadays due to increasing numbers of upper gastrointestinal and bariatric surgeries being performed. First treatment step includes dietary adjustment and dietary supplements, which are often sufficient to manage symptoms for the majority of patients. Next step of therapy includes acarbose, which is effective for late dumping symptoms, but the use is limited due to side effects. Somatostatin analogues are indicated after these two steps have failed. Somatostatin analogues are very effective for controlling early and late dumping, also in the long term. Glucagon like peptide-1 receptor agonists, endoscopic and surgical (re)interventions are reported as treatment options for refractory dumping syndrome; however, their use is not recommended in clinical practice due to the limited evidence on and uncertainty of outcomes. These alternatives should be considered only as last resort options in patients with otherwise refractory and invalidating dumping syndrome.

Metabolic and Bariatric Endoscopy: A Mini-Review

We are currently in a worldwide obesity pandemic, which is one of the most significant health problems of the 21st century. As the prevalence of obesity continues to rise, new and innovate treatments are becoming available. Metabolic and bariatric endoscopic procedures are exciting new areas of gastroenterology that have been developed as a direct response to the obesity crisis. These novel interventions offer a potentially reversible, less invasive, safer, and more cost-effective method of tackling obesity compared to traditional bariatric surgery. Minimally invasive endoscopic treatments are not entirely novel, but as technology has rapidly improved, many of the procedures have been proven to be extremely effective for weight loss and metabolic health, based on high-quality clinical trial data. This mini-review examines the existing evidence for the most prominent metabolic and bariatric procedures, followed by a discussion on the future trajectory of this emerging subspecialty.

Bariatric endoscopy: from managing complications to primary metabolic procedures

Obesity is a worldwide epidemic and is the second leading cause of preventable death. The approach to treating obesity involves a multidisciplinary approach including lifestyle interventions, pharmacological therapies, and bariatric surgery. Endoscopic interventions are emerging as important tools in the treatment of obesity with primary and revisional bariatric endoscopic therapies. These include intragastric balloons, aspiration therapy, suturing and plication, duodenal-jejunal bypass liners, endoscopic duodenal mucosal resurfacing, and incisionless magnetic anastomosis systems. Endoscopic interventions have also demonstrated efficacy in treating complications of bariatric surgery. Approaches include stenting, endoscopic internal drainage, and endoscopic vacuum-assisted closure. This review aimed to discuss the current endoscopic procedures used as primary and revisional bariatric therapy including those used for managing bariatric surgical complications.

[Management of Endoscopic Complications after Bariatric Surgery: Focus on Current Endoscopic Therapy]

In bariatric surgery, complications are rare. Most of the complications can be managed by endoscopy. Rare complications impose a challenge in everyday clinical work. To optimally treat the complications and to minimise the harm to the patient it is important to implement complication management. This review gives an overview of relevant bariatric complications and endoscopic therapy strategies, focusing on published literature of the last five years. This manuscript could be a starting point for complication management in the clinic.
