Dumping Syndrome After One Anastomosis Gastric Bypass-A Systematic Review

Area of Science:

• Metabolic and Bariatric Surgery
• Gastroenterology
• Surgical Outcomes

Background:

• One anastomosis gastric bypass (OAGB) is a prevalent bariatric procedure globally.
• Long-term complications, particularly dumping syndrome (DS), require further investigation.
• Understanding DS incidence is crucial for patient management and surgical evaluation.

Approach:

• Systematic review of published literature from PubMed and Scopus.
• Inclusion of 17 studies encompassing 3420 patients.
• Analysis of DS incidence based on standardized scoring and patient self-reporting.

Key Points:

• DS incidence varied significantly: 9-42.9% (Sigstad score) vs. 0.5-27.8% (patient-reported).
• Postoperative follow-up averaged 11.91 months.
• Primary treatments for DS included dietary modifications and pharmacotherapy.

Conclusions:

• Dumping syndrome appears to be a rare long-term complication following OAGB.
• Current evidence suggests revisional or conversion surgeries may not be routinely necessary for DS.
• Long-term outcomes of OAGB require continued monitoring and research.
