Embolization of the vasa recta in acute lower gastrointestinal hemorrhage: A report of five cases.

PURPOSE: To present our preliminary experience in embolization of the vasa recta in acute gastrointestinal hemorrhage. METHODS: In four of five patients with acute gastrointestinal hemorrhage superselective embolization of the vasa recta was performed. In one patient in whom superselective catheterization of the bleeding vas rectum was technically impossible, the origin of this vessel was embolized at the level of the terminal arcade. The following embolization materials were used: microcoils and polyvinyl alcohol particles (355-500 microm), n = 2; microcoils only, n = 2; Gelfoam particles, n = 1. RESULTS: Bleeding was found in two patients in the small bowel (jejunum and ileum) and in three patients in the colon. Immediate hemostasis was achieved in all patients. No signs of ischemia or infarction were observed after intervention. CONCLUSIONS: Superselective embolization of the vasa recta proved efficient and safe in our small patient group. Advantages of this technique are reduction of the embolized area to a minimum and direct control of hemostasis.

Superselective coil embolization in acute gastrointestinal hemorrhage: personal experience in 10 patients and review of the literature.

PURPOSE: To evaluate the safety and efficiency of microcoil embolization in upper and lower gastrointestinal hemorrhage. PATIENTS AND METHODS: Superselective microcoil embolization was performed in 10 patients (upper gastrointestinal bleeding, n = 3; lower gastrointestinal bleeding, n = 7) who had acute gastrointestinal hemorrhage. Embolization was performed as peripherally as possible with use of coaxial catheter systems. Embolization materials included microcoils (2-4 mm) alone (n = 5), microcoils and polyvinyl alcohol particles (355-500 microm) (n = 4), and microcoils and gelatin sponge particles (n = 1). RESULTS: Immediate hemostasis was achieved in eight patients. In two patients with dual blood supply of the bleeding site, significant reduction of hemorrhage resulted. In these two patients, it was technically impossible to place the coaxial catheter distally enough to allow safe embolization of both feeding vessels. No clinical signs of ischemia or infarction were observed after intervention. CONCLUSION: Microcoil embolization is a safe and efficient procedure for controlling acute lower gastrointestinal bleeding if performed in a superselective catheter position. In upper gastrointestinal bleeding, microcoil embolization is an established treatment and can be performed more proximally.

Milk formulae in the prevention of food allergy.

Because food allergy is frequent and severe, all possible means should be used to try to prevent its manifestations or at least to delay them until the child is older and stronger and therefore better able to follow an exclusion diet. The capacity of breast-feeding for preventing food allergy has been challenged in the past, but a consensus seems to be emerging now that breast-feeding can indeed prevent food allergy if it is started at birth and is exclusive for at least 4, and preferably 6, months. In the most "at-risk" babies the breast-feeding mother should try to eliminate the most potent allergens (eggs, fish, soya, nuts, and cow's milk) from her diet. If a substitute or a complement to breast milk is necessary, neither goat's milk nor soy milk formula are adequate. Heat treatment alone will not be sufficient to make cow's milk hypoallergenic. Only a combination of protein hydrolysis and managed heat treatment can make cow's milk hypoallergenic and retain its nutritional value. This nutritional value should be assessed by animal studies and also by studying infant growth. The hypoallergenicity of a formula can be studied in vitro and with animal tests, but only clinical trials on human infants will prove its efficacy.
