闭合广术野全喉切除术后的下咽部,通常缝合粘膜和粘膜下二层,如有可能,再缝合肌层加固。缝合方法常呈垂直或“T”形。本研究通过钡餐X线照相,确定那种缝合法其早期术后下咽部解剖结构较好,并分析术后并发症及其与闭合方式和缝合方法的关系。本文报告37例标准术式的喉切除术,下咽部粘膜用3-0铬羊肠线缝合,分别采用垂直缝合和“T”形缝合,并都包括简单间断缝合和连续的Connell缝合。开始进食前,一般在喉切除后10～14天作钡餐X线照相。检查术后吞咽困难、瘘或颈段食管狭窄等并发症,并研究术前或术后化疗和/或放疗对随后并发症的影响。可供研究的28例均为男性,术后钡餐侧位X线片中,21例在下咽前壁近舌底部有一像会厌的结构。该假会 Close the hypopharynx after total laryngectomy, usually by suturing the mucous membranes and the submucosa. If possible, re-suture the muscle reinforcement. Stitching methods are often vertical or “T” shaped. In this study, barium meal X-ray photographs were used to determine the early postoperative postoperative pharyngeal anatomy of the kind of suturing method, and to analyze the postoperative complications and its relationship with closure and suturing methods. In this paper, 37 cases of standard laryngectomy were reported. The hypopharynx mucosa was sutured with 3-0 chromic catgut and vertical sutures and “T” sutures were used. Both included simple interrupted sutures and continuous Connell sutures. Before starting to eat, a barium meal is usually taken 10 to 14 days after the laryngectomy. Examine postoperative complications such as dysphagia, spasticity or cervical esophageal stenosis, and study the effect of preoperative or postoperative chemotherapy and/or radiotherapy on subsequent complications. All the 28 cases available for study were male. In the postoperative X-ray film of the barium meal, 21 cases had an epiglottis structure near the bottom of the tongue. The fake meeting
