Dumping syndrome after bariatric surgery: prevalence, pathophysiology and role in weight reduction - a systematic review.
Background: Dumping syndrome is a frequent and wellknown adverse event after bariatric surgery and covers a dynamic spectrum of early and late dumping. Accelerated gastric emptying is generally considered to be the cause of gastrointestinal and vasomotor complaints. However, there is much uncertainty regarding the exact pathophysiology of dumping. It has been speculated that the syndrome is a desired consequence of bariatric surgery and contributes to more efficient weight loss, but supporting data are scarce.
Methods: A systematic search was conducted in PubMed in July-August 2021. The prevalence of dumping after the most frequently performed bariatric procedures was analyzed, as well as underlying pathophysiology and its role in weight reduction.
Results: Roux-en-Y gastric bypass (RYGB) is associated with the highest postoperative prevalence of dumping. The fast transit induces neurohumoral changes which contribute to an imbalance between postprandial glucose and insulin levels, resulting in hypoglycemia which is the hallmark of late dumping. Early dumping can, when received in a positive way, become a tool to maintain a strict dietary pattern, but no significant relationship to the degree of weight loss has been shown. However, late dumping is detrimental and promotes overall higher caloric intake.
Conclusion: Dumping syndrome is common after bariatric surgery, especially after RYGB. The pathophysiology is complex and ambiguous. Currently available data do not support dumping as a necessary condition to induce weight loss after bariatric surgery.
期刊介绍:
The Journal Acta Gastro-Enterologica Belgica principally publishes peer-reviewed original manuscripts, reviews, letters to editors, book reviews and guidelines in the field of clinical Gastroenterology and Hepatology, including digestive oncology, digestive pathology, as well as nutrition. Pure animal or in vitro work will not be considered for publication in the Journal. Translational research papers (including sections of animal or in vitro work) are considered by the Journal if they have a clear relationship to or relevance for clinical hepato-gastroenterology (screening, disease mechanisms and/or new therapies). Case reports and clinical images will be accepted if they represent an important contribution to the description, the pathogenesis or the treatment of a specific gastroenterology or liver problem. The language of the Journal is English. Papers from any country will be considered for publication. Manuscripts submitted to the Journal should not have been published previously (in English or any other language), nor should they be under consideration for publication elsewhere. Unsolicited papers are peer-reviewed before it is decided whether they should be accepted, rejected, or returned for revision. Manuscripts that do not meet the presentation criteria (as indicated below) will be returned to the authors. Papers that go too far beyond the scope of the journal will be also returned to the authors by the editorial board generally within 2 weeks. The Journal reserves the right to edit the language of papers accepted for publication for clarity and correctness, and to make formal changes to ensure compliance with AGEB’s style. Authors have the opportunity to review such changes in the proofs.
