Few organs are more easily exposed and mobilized than are loops of small intestine; adhesions from previous surgery are the chief obstacles. Detailed step-by-step technique is given for jejunostomy and resection of small bowel for tumor. The surgeon should always be conservative. In benign disease, the ileocecal valve should be spared. There is no good way to identify an isolated loop of small intestine without following it in one direction to the duodenojejunal junction or in the other direction to the ileocecal junction.
An intussusception is created when a proximal segment of intestine (the intussusceptum) invaginates into the portion of intestine immediately distal to it (the intussuscipiens). Meckel’s diverticulum is the most common form of intussusception in children.
