[Acute Pancreatitis as a Result of Supramesocolic Ischemia after Scoliosis Surgery].

Ischemic complications in the supramesocolic anatomical region with the development of acute pancreatitis due to compression of the celiac artery or superior mesenteric artery are rare but potentially serious complications after major spine surgery. A case report of two patients with idiopathic scoliosis who underwent posterior instrumented correction and fusion with subsequent development of acute pancreatitis due to vascular compression of the retroperitoneum is presented. The manifestation of an acute abdomen within 24 hours after the surgery with elevation of pancreatic obstruction enzymes and confirmation of acute pancreatitis on CT angiography with abdominal pain, gastrectasia, and ileus clinical findings. In both cases, due to the clinical progression, acute revision spinal surgery was performed with release of the original deformity correction. Subsequently, in combination with conservative treatment of the acute abdomen, both patients achieved full clinical recovery.
