作者对４７例胸段食管癌手术中保留迷走神经干行分组对比研究，其中保留神经组２０例，常规手术对照组２７例。保留组１８例和对照组２６例行根治性手术；余为姑息性手术。病理学检查发现保留组３例（１５．０％）和对照组３例（１１．１％）癌已浸润近迷走神经干或／和其分支附近；另外，保留组１例（５．０％）和对照组３例（１１．１％），癌已侵及神经。基础胃酸分泌量（ＢＡＯ）及胃排空时间（Ｔ１／２）测定：保留组ＢＡＯ均数值（１．９３ｍｍｏｌ／ｈ）和Ｔ１／２均数值（６３．５１分）与对照组ＢＡＯ（０．７５ｍｍｏｌ／ｈ）和Ｔ１／２（＞１０５分）之间的差别皆显著；而与正常人组和术前对照组相比则差异无显著性意义。作者认为，术中保留迷走神经是可行的，术后胃的泌酸及运动功能损伤轻。但手术指征应限于Ｔ１～Ｔ２等较早期的病变，否则会影响手术的根治性。
The authors grouped contrast-retained vagal nerve trunks in 47 cases of thoracic esophageal carcinoma during surgery, including 20 cases of nerve preservation group and 27 cases of conventional surgical control group. 18 patients in the retention group and 26 in the control group underwent radical surgery; the remainder were palliative. Pathological examination revealed that 3 patients (15.0%) in the retained group and 3 (11.1%) in the control group had cancer infiltrated near the vagus nerve trunk and/or its branches; in addition, 1 patient (5.0%) in the retained group. And in the control group, 3 patients (11.1%) had invaded the nerves. The basal gastric acid secretion (BAO) and gastric emptying time (T1/2) were determined: the mean BAO values (1.93 mmol/h) and the mean T1/2 values (63.51 points) in the reserved group and the control group BAO (0. The difference between 75mmol/h) and T1/2 (>105 points) was significant; while there was no significant difference between the normal group and the preoperative control group. The authors believe that it is feasible to retain the vagus nerve during the operation, and that the postoperative gastric acid and motor function are lightly damaged. However, surgical indications should be limited to earlier lesions such as T1 ~ T2, otherwise it will affect the radical surgery.
