• Fig GI 29-1 Crohn's disease. Marked thickening of the mesentery and mesenteric nodes produces a lobulated mass that widely separates small bowel loops.

• Fig GI 29-2 Intestinal hemorrhage with bleeding into the bowel wall and mesentery.

Fig GI 29-3 Carcinoid tumor. Localized separation of bowel loops with luminal narrowing and fibrotic tethering of mucosal folds.

• Fig GI 29-4 Carcinoid tumor. An intense desmoplastic reaction incited by the tumor causes kinking and angulation of the bowel and separation of small bowel loops in the mid-abdomen.

• Fig GI 29-5 Retractile mesenteritis.36

• Fig GI 29-6 Right paraduodenal hernia. The loops of bowel crowded together in the hernia sac (arrows) are widely separated from other segments of small bowel that remain free in the peritoneal cavity.
