Total parenteral nutrition.C. Division of the ligament of Treitz and duodenal mobilization.D. Percutaneous endoscopic gastrostomy.E. Duodenojejunostomy.Answer: BCEDISCUSSION: Vascular compression of the duodenum is best treated initially with supportive care. Of paramountimportance is supplying adequate nutrition, since most patients have significant weight loss with this syndrome. This canbest be done with a nasojejunal feeding tube placed past the ligament of Treitz (and the obstructed area). Gastrostomyalone does not provide unobstructed enteral access. Parenteral nutrition may be used successfully when enteral accesscannot be established. When operative therapy is needed, duodenojejunostomy has been the most common and successfuloperation and is the treatment of choice for adults. In the pediatric population, division of the ligament of Treitz andduodenal mobilization has also proved successful. Gastrojejunostomy has been used, but with a lower overall success rate.Distal gastrectomy usually worsens duodenal obstruction by preventing duodenogastric reflux.
