下咽颈食段食管环周缺损修复方法的探讨

目的探讨不同手术方法修复重建下咽颈食管环周缺损的适应证，对不同方法的优缺点进行比较。方法对1993年6月至2006年6月期间收治的72例下咽颈食管区肿瘤进行手术切除，并根据肿瘤切除术后缺损的范围，采用胸大肌肌皮瓣、喉管、游离空肠、游离前臂皮瓣和胃上提咽胃吻合5种方法对肿瘤切除术后所致的下咽颈食管环周缺损进行一期修复重建，并重点对所有患者术后的吞咽功能恢复情况进行观察和客观评估。结果胸大肌肌皮瓣修复重建31例，喉管代下咽颈食管8例，游离空肠移植12例，游离前臂皮瓣移植4例，胃上提咽胃吻合术17例。其中15例患者出现了不同程度的并发症，包括创口感染、咽漏、皮瓣部分坏死、胃壁部分坏死和食管吻合口狭窄等，除1例死亡外，其他患者经处理全部治愈。本组患者术后吞咽功能恢复满意，除2例食管吻合口狭窄患者可以进半流食外，其余患者均恢复了正常的进食功能。平均随访时间为1．6年，术后2年生存率为45．3％。结论下咽颈段食管癌切除术后所致的环周缺损可依据缺损的范围和患者的情况选择不同的修复方法，只要适应证掌握得当均可获得满意的修复重建效果。

Multi-modalities for reconstruction of circumferential defects in the pharyngoesophageal region

OBJECTIVE: To investigate the feasibility of multi-modalities in the reconstruction of circumferential defects after resection of cancers in pharyngoesnphageal regions, and to compare the pros and cons between different surgical procedures. METHODS: According to the nature and extend of defects, five different methods including pectoralis major myocutaneous flap, laryngeal tube replacement, free jejunum, free forearm flap and gastric pull-up were used to reconstruct the circumferential pharyngoesophageal defects in 72 patients. Function of deglutition and restoration of swallowing was regularly followed up and objectively evaluated. RESULTS: A total of 35 cases of pectoralis major myocutaneous (PM) flaps, 8 cases of laryngeal tube replacement, 12 cases of free jejunum, 12 cases of free forearm flaps and 16 cases of gastric pull-up were performed. Different complications including wound infection, pharyngeal fistula, partial necrosis of PM flap, partial necrosis of gastric wall, stricture of anastomostic site were encountered in 15 cases. All patients survived the operation except one due to partial necrosis of the gastric wall. Two of 4 patients who developed anastomostic stricture can ingest half-liquid food, the remaining cases regained normal deglutition function. The mean postoperative follow-up time was 1. 6 years with 2-year survival rate of 45.3%. CONCLUSIONS: Circumferential defects resulting from resection of carcinomas in pharyngoesophageal region can be reconstructed with different operative techniques depending on the nature and extend of the defects. Once the operative indications are properly selected, the good reconstructive results are to be achieved.
