目的：通过对下咽癌、颈段食管癌病人行保留迷走神经干的喉及食管全切除后，以结肠代食管的术式，探讨保留迷走神经干的可行性，及保留消化道生理功能的优越性。方法：10例下咽癌颈段食管癌病人行保留迷走神经干及腹腔各分支，连同胃留在腹腔内的喉全切除和食管切除，以结肠代食管；另5例病人行喉及食管全切除，不保留迷走神经，以胃代食管，比较两组病人的消化道功能。结果：保留组术后腹胀、腹泻、返流及相关生理指标明显好于不保留级。结论：下咽癌及颈段食管瘤病人在做喉及食管全切除时保留迷走神经干是可行的，有利于患者术后消化功能的保护，提高病人的术后生活质量。
OBJECTIVE: To evaluate the feasibility of preserving the vagus nerve stem and to preserve the superiority of the digestive tract physiological function by using the colon replacement esophagus after hypothalamic and esophageal resection of patients with hypopharyngeal carcinoma and cervical esophageal cancer. . METHODS: Ten patients with hypopharyngeal carcinoma of the neck with esophageal cancer underwent vagotomy and abdominal branches, total resection of the larynx and esophagectomy with intragastric resection in the abdomen, and replacement of the esophagus in the colon. The other 5 patients underwent total resection of the larynx and esophagus. The vagus nerve was not preserved, and the digestive tract function was compared between the two groups of patients. RESULTS: Abdominal distention, diarrhea, regurgitation, and related physiological parameters in the retained group were significantly better than those in the non-retained group. Conclusion: Hypopharyngeal carcinoma and cervical esophageal tumors are feasible in patients with total excision of the vagus nerve during excision of the larynx and esophagus, which is beneficial to the protection of patients’ postoperative digestive function and improve their postoperative quality of life.
