True about mesenteric vein thrombosis -

Peritoneal signs are present in less than half the cases. Any length of bowel may be involved depending on the level and extent of thrombosis. Resection of the nonviable bowel along with its, mesentry is the treatment of choice. Heparin is given in all cases and along with bowel rest and fluid resuscitation is sufficient in patients without bowel infarction. When extensive resection is done, short bowel syndrome can occur.
