Fluid resuscitation
Analgesia
Antibiotics with bowel coverage if perforation or gangrene suspected (e.g. ceftriaxone plus flagyl)
Emergent surgery consult
Gastric<unk> 
Endoscopic reduction
Recurrence possible, which would mandate surgical repair
Cecal<unk>  always requires surgical repair with resection (preferred) or cecopexy
Endoscopy relatively contraindicated in signs of ischemia such as significantly elevated lactate
Sigmoid<unk>  may be managed with endoscopic decompression/detorsion (if no signs of gangrenous bowel/perforation)
