Pharyngocutaneous fistula is a serious complication after laryngectomy. Gastric fluid is known to cause severe laryngopharyngeal injury and poor mucosal healing. This study was designed to evaluate the effects of a gastroesophageal reflux prophylaxis regimen on the incidence of fistula after laryngectomy. Twenty-one consecutive patients were entered in the study. Patients with positive resection margins were excluded from the overall analysis. All patients had a Connell's two-layer closure of the pharynx with absorbable suture, suction drainage of the neck, postoperative tube feeding, and prophylactic antibiotics. All patients were started on an antireflux regimen postoperatively composed of continuous tube feeds, intravenous ranitidine, and intravenous metoclopramide hydrochloride. Patients were followed postoperatively with Gastrografin swallows and clinically for 8 weeks. The control group consisted of retrospectively studied patients managed identically except for the antireflux prophylaxis. The two groups were well matched for factors reported to influence the rate of pharyngocutaneous fistula formation. The control group had six fistulae (26%) and an average of 16.5 days of hospital stay. The study group had no fistulae and an average of 11.5 days of hospital stay (P = .02). This study suggests that gastroesophageal reflux may predispose to fistula formation after laryngectomy and that mechanical and pharmacological prophylaxsis decreases postoperative morbidity and length of hospital stay.
咽皮肤瘘是喉切除术后的一种严重并发症。已知胃液会导致严重的喉咽损伤和黏膜愈合不良。本研究旨在评估一种胃食管反流预防方案对喉切除术后瘘发生率的影响。连续21例患者纳入本研究。切缘阳性的患者被排除在总体分析之外。所有患者均采用可吸收缝线进行Connell双层咽闭合术、颈部负压引流、术后管饲及预防性使用抗生素。所有患者术后均开始采用由持续管饲、静脉注射雷尼替丁和静脉注射盐酸甲氧氯普胺组成的抗反流方案。术后对患者进行泛影葡胺吞咽检查及临床随访8周。对照组由回顾性研究的患者组成,除未进行抗反流预防外,其他处理相同。两组在据报道影响咽皮肤瘘形成率的因素方面匹配良好。对照组有6例瘘(26%),平均住院天数为16.5天。研究组无瘘,平均住院天数为11.5天(P = 0.02)。本研究表明,胃食管反流可能易导致喉切除术后瘘的形成,机械和药物预防可降低术后发病率和住院时间。
