Endoscopic treatment of acute gastric volvulus causing cardiac tamponade

Acute gastric volvulus occurs when the stomach, or part of the stomach, rot ates more than 180 degrees, creating a closed-loop obstruction, which event ually leads to ischemia and strangulation. Acute gastric volvulus may occur in association with a diaphragmatic defect, diaphragmatic elevation of any cause, tumors of the pancreas and stomach, trauma, and congenital abnormal ities of mesenteric fixation. We describe an unusual case of an acute gastr ic volvulus causing cardiac tamponade, which was successfully treated by en doscopic reduction of the gastric volvulus.
