Segmental intestinal preservation and enteral nutrition help to maintain the intestinal function after a massive...

We report a case in which both segmental intestinal preservation and enteral nutrition helped to maintain the intestinal function after a massive bowel resection for superior mesenteric artery (SMA) thrombosis. A 53-year-old Japanese man was admitted to our hospital with acute abdomen. Extensive necrosis of the small intestine was found during the operation; however, a loop of the ileum appeared to be viable. A massive resection of the small intestine which preserved a 50-cm length of the viable ileum loop was thus performed. However, diffuse stenosis of the remaining ileum was found after surgery. An end-to-end anastomosis of the distal end of the preserved ileum loop and the terminal ileum was made in the second operation, and enteral nutrition was infused to improve the remnant intestinal function. A jejunoileostomy was performed in the final operation. An X-ray study after the final operation showed the stenosis of the remaining ileum to have improved. The patient therefore did not need any nutritional support after being discharged.
