ABSTRACT
Objective To investigate the method and curative effect of the posterior cervical esophageal de-fect after the reconstruction of lower pharyngeal carcinoma by dissociation of the lower pharyngeal carcinoma. Meth-ods From August,2015 to June,2017, we used the jejunum segment. to reconstruct five patients' esophageal defect in the neck segment enlarged after the enlargement of the hypopharyngeal carcinoma. The length of the jejunum was 8.0 -15.0 cm, We used microvascular stapling to anastomosis vein in surgery. The morphological and functional changes of the graft tube were observed by endoscopic follow-up. Results All 5 patients were discharged from the hospital with an average of 12 days in hospital.The mean time of heat ischemia was 8 minutes,and the average oper-ation time was 5.2 hours. After endoscopic follow-up for 12 months, no stricture or anastomotic leakage occurred in the transplanted bowel, and the intestine moves downward autonomously, the morphological and functional remodeling of transplanted intestinal tract was observed. Conclusion Free jejunal reconstruction of hypopharyngeal carcinoma resection for cervical esophageal is a safe method with a good outcome in morphological and functional remodeling.It' s one of the ideal methods to reconstruct cervical esophageal defect.
