ABSTRACTS
262 Intrauterine Production of Coarctation of the Aorta: Studies of Hemodynamics and Collateral Aortic Circulation in Newborn Animals. J. A. Hailer, Jr., I. J. Shaker, R. Gingell, and C. Ho. J. Thorac. Cardiovasc. Surg. 66:343-349 (September), 1973. P r e - o r postductal coarctations were produced in seven fetal lambs. Aortograms were obtained in all seven within 2 hr of birth. There was no significant hemodynamic difference between the pre- and postductal position of the coarctation. The ductus closed in both groups. There did not appear to be any difference in the amount of collaterals with the pre- or postductal coarctation.--Thomas M. Holder
ALIMENTARY TRACT The Gastric Tube for Esophageal Replacement in Children. K. D. Anderson and J. G. Randolph. J. Thorac. Cardiovasc. Surg. 66: 333-342 (September), 1973. The gastric tube is advocated for esophageal replacement for patients with failed colon replacement, patients with anal or colonic anomalies who require esophageal replacement or as an alternative to colon interposition. Seven patients (three patients with esophageal atresia without tracheoesophageal fistula and four patients with caustic burns of the esophagus) treated with gastric tube replacement are presented. Three developed cervical anastomotic stricture and one with a caustic burn required operative revision. This patient also required surgical correction of a pyloric obstruction. One gastric tube was perforated during dilatation, A third patient developed an ulcer in the distal end of the gastric tube which responded to treatment with antacids. There were no deaths.-- Thomas M. Holder Esophageal Reconstruction for Stenosis Due to Diffuse Scleroderma. H. Akiyama, T. Kogure, and U. ltai. Arch. Surg. 107:470-472, 1973. Esophageal stenosis secondary to scleroderma occurred in an 18-yr-old boy. Esophageal resection was performed utilizing both cervical and paramedian incisions. Thoracotomy was not employed. The stomach was brought through the posterior tunnel created by the esophageal resection and anastomosed in the neck to the cervical esophagus. Good results were obtained.--E. Berman
Pharmacological Prevention of Esophageal Stricture: An Experimental Study in the Cat. S. Saedi, L. M. Nyhus, B. F. Gabrys, K. Kusakari, and C. T. Bombeck. Am. Surg. 39:465 469, 1973. B-aminoproprionitrile acts as an inhibitor of lysine oxidation and interrupts the process of collagen formation and or maturation. It will prevent experimental esophageal stricture in cats when given in doses that do not produce other side effects and is comparable to or more effective than hydrocortisone.--E. Berman Removal of Coins in the Esophagus Using a Foley Catheter. D. Carlson. Pediatrics 50: 475 (September), 1972. The author described a technique in dislodging a coin stuck in the esophagus in the area of the cricopharyngeus. A well lubricated No. 10 French Foley catheter is passed through the nose, well past the level of the coin. With the patient lying on his side the balloon is inflated with 5 cc of air and drawn up to the level of the coin using fluoroscopic control. Usually the pressure from below causes the coin to be ejected into the pharynx where it is easily dislodged with a finger. If this is not successful, then the coin may be dislodged caudad into the stomach. The author reports no complications but warns of the rare possibility of aspiration. Clifford Rubin Emergency Oesophageal Transection in Uncontrolled Variceal Haemorrhage. P. George, C. Brown, G. Ridgway, B. Crofts, and S. Sherlock. Br. J. Surg. 60:635-640 (August), 1973. The overall operative mortality for the above procedure was 45~o, 16 out of 35 patients. All the deaths were in patients with intrahepatic obstruction in adults. Five had extrahepatic obstruction, all were children. Two had suffered from neonatal sepsis. All the extrahepatic obstructions were well following operation, and only one had any hemorrhage, but the followup is short, the longest being 6 yr.--J.

Gut, 14:59-63, 1973. The results of treatment of massive bleeding from esophageal varices using continuous infusions of vasopressin into the superior mesen-
