食管癌外科手术后器官机能变化

Organ Functions before and following Surgery on Patients with Esophageal Cancer

本文报道食管癌患者术后胃泌酸能力下降,腹腔胃肠运动亢进,十二指肠移位变形,胸胃蠕动减弱,肢体出现隐性水肿。上述变化与胃肠移位、切断迷走神经、胃粘膜萎缩和低蛋白血症等有关。建议手术时不加作幽门成形术,进食后应半卧位休息。术后肺功能降低,程度与全肺切除近似,应重视该项检查,术中注意保护肺功能。循环系统功能变化不明显,选例时可以放宽对心脏的要求。器官机能降低程度与手术并发症发生率一致,提示二者有一定关联。

Changes of organ function after surgery on patients with esophageal cancer are reported. The conclusions are as follows: 1. Gastroenteric function test results showed that gastric secretion decreased and gastroenteric motion activated. Covert undernourishment manifested by edema of the arms and legs was observed. 2. Vital capacity and maximum breathing capacity were reduced by 20.51％ and 21.86％ respectively. Similar changes were observed after esophagectomy and pneumonectomy as well. 3. Changes of cardiovascular system were insignificant. These findings suggest that changes of organ function consort with frequency of complications in postoperative period of patients with esophageal cancer. Effort should be made to better selection of patients and surgical technique as well as rehabilitative management on the basis of the above-mentioned observations.
