Background:
Early or late pouch dilatations account for a moderate complication rate after restrictive bariatric operations. Various strategies were developed to prevent or treat pouch dilatations.
Methods:
A case of necrosis of gastric wall in a concentric dilated pouch following laparoscopic adjustable gastric banding is reported as a severe complication of a conservative treatment attempt.
Results:
Emergency laparotomy resulted in band removal, partial gastric resection and prolonged hospital stay.
Conclusion:
Conservative strategies in the treatment of pouch dilatations bear the risk of complications, with both failure of the bariatric procedure and critical clinical course. Indication for early operative reintervention is recommended.

The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
