颈段食管癌手术喉功能保留问题的探讨

目的:探讨颈段食管癌手术喉功能保留的适应证和咽食管重建方法, 以及胃咽吻合术误吸并发症的原因和防治措施.方法:9例保留喉功能的颈段食管癌手术患者,其中单纯颈段食管癌2例,颈段食管癌侵犯下咽部6例,颈胸段食管重复癌1例.喉功能保留:全部喉功能保留8例,部分喉功能保留1例.下咽-食管重建:胃咽吻合7例,游离前臂皮瓣1例, 胸大肌皮瓣1例.结果:喉功能恢复良好4例,中等2例,差3例.胃咽吻合术7例均发生不同程度的胃液反流、咳嗽反射暂时性消失和误吸,5例发生声带麻痹;吻合口越高,误吸程度越重.游离前臂皮瓣移植术1例死于大出血.胸大肌皮瓣转移术1例虽能恢复良好的喉功能,但6个月后发生吻合口狭窄.结论:单纯颈段食管癌和颈段食管癌向上侵犯下咽部1 cm以内的患者适宜行全部喉功能保留手术;而颈段食管癌向上侵犯下咽部部1 cm以上的高龄患者不宜行全部喉功能保留手术,可行部分喉功能保留手术或不保留喉功能手术.胃咽吻合术误吸并发症的发生与咽-食管吞咽功能障碍和喉防误吸功能障碍密切相关.

Laryngeal function preservation in the surgical treatment of cervical esophageal carcinoma

Objective:To study the indication and the methods of hypopharyngeal and esophageal reconstruction in the surgical treatment of cervical esophageal carcinoma with laryngeal function preservation. To explore the reasons of err inhaling after gastric-pharyngeal anastomosis and its prevention and treatment.Method:Clinical data of nine patients who underwent surgical treatment of cervical esophageal carcinoma with laryngeal function preservation from 1998 to 2006 were analyzed retrospectively. The patients without preoperative hoarseness included two cases of pure cervical esophageal carcinoma, six cases of cervical esophageal carcinoma involved hypopharynx and one cases of cervical-thoracic esophageal poly primary malignant carcinoma . Eight patients were carried out total laryngeal function preservation and one patient was carried out partial laryngeal function preservation. The methods of hypopharyngeal and cervical esophageal reconstruction included gastric-pharyngeal anastomosis(seven patients), free forearm flap(one patient) and pectoralis major myocutaneous flap(one patient).Result:Good laryngeal function in four patients, moderate laryngeal function in two patients and bad laryngeal function in three patients. Everyone in seven patients underwent gastric-pharyngeal anastomosis had a very degree of gastric countercurrent, temporalitive disappearance of cough reflex and err inhaling,five of them laryngeal paralysis.The higher anastomosis gob, the heavier err inhaling. One patient with free forearm flap died of lethal haemorrhage. One patient with pectoralis major myocutaneous flap occurred anastomosis gob stricture.Conclusion:Patients with pure cervical esophageal carcinoma and cervical esophageal carcinoma involved hypopharynx less than 1cm from the entrance of esophagus are feasible to undergo total laryngeal function preservation operation, while elder patients with cervical esophageal carcinoma involved hypopharynx more than 1 cm from the entrance of esophagus are feasible to undergo partial laryngeal function preservation operation or no laryngeal function preservation operation instead of total laryngeal function preservation operation. Err inhaling is nearly relevant to the disorder of deglutition function of the pharynx -esophagus and err inhaling prevention function of the larynx.
