Introduction: Obesity is a global epidemic and has become a public health crisis in the United States. Bariatric surgery is considered the most effective way to achieve long term weight loss. Roux-n-Y gastric bypass (RYGB) and sleeve gastrectomy are two of the most commonly performed bariatric procedures. Most significant complications are staple line bleeding, stricture, and staple line leak. Formation of liver abscess without intra-abdominal infectious process is a rare complication after bariatric surgery.
Methods and Procedures: Two cases of liver abscesses after revisional bariatric surgery.
Results: We report two cases of pyogenic liver abscesses after laparoscopic gastric bypass revision and sleeve gastrectomy. These were managed by percutaneous drainage and antibiotics.
Conclusion: Liver abscess is a rare complication of revisional bariatric surgery and could be due to multiple factors; it could be due to a clinical leak, subclinical leak, pyelophlebitis of the porto-mesenteric veins or from the combination of parenchymal liver injury and bacterial seeding from staple line when leak is not evident. Most liver abscesses respond to percutaneous drainage and antibiotic administration.
