Nitrogen balance studies and clinical observations were made on two groups of patients suffering from obstructive carcinoma of the oesophagus. In 10 patients (group A) parenteral nutrition with a high calorie and nitrogen content was given pre- and early postoperatively. Five patients (group B) received intravenous dextrose/saline solution pre- and postoperatively with no nitrogen supply. Patients in group A had a positive nitrogen balance before and after operation and had a satisfactory postoperative progress. The patients in group B had a negative nitrogen balance until the resumption of oral feeding and their postoperative progress was not as satisfactory as that of patients in group A.
对两组患有食管梗阻性癌的患者进行了氮平衡研究和临床观察。10例患者（A组）在术前及术后早期给予高热量、高氮含量的肠外营养。5例患者（B组）在术前及术后接受静脉输注葡萄糖/盐水溶液，不供应氮。A组患者在手术前后氮平衡为正，术后恢复良好。B组患者直到恢复经口进食前氮平衡为负，其术后恢复情况不如A组患者满意。
