Abstract：
Pharyngocutaneous fistula (PCF) is an abnormal connection between the pharynx and skin that can occur after laryngectomy surgery. It can have a significant negative impact on patient recovery, delaying wound healing, requiring prolonged nil-per-oral (NPO) status, and reducing quality of life. Traditionally, the management of PCF has relied on conservative measures or surgical intervention. However, negative pressure wound therapy (NPWT) offers a promising alternative approach. This case study involves three patients who underwent laryngectomy and developed postoperative PCF. All patients received NPWT with a modified suction catheter and low negative pressure (20-40 mmHg). With NPWT, all patients achieved complete wound closure, with healing times ranging from two weeks to six weeks. This suggests that NPWT may significantly accelerate PCF healing compared to traditional methods. However, maintaining an airtight dressing on the neck region can be challenging. This study highlights the potential of NPWT for faster PCF closure after laryngectomy. Further research is needed to optimize NPWT application techniques, explore the impact on long-term outcomes, and establish guidelines for broader clinical use.
摘要：
咽部皮肤瘘（PCF）是咽部和皮肤之间的异常连接，可在喉切除术后发生。它会对患者的康复产生重大的负面影响，延迟伤口愈合，需要长时间的无口服(NPO)状态，降低生活质量。传统上,PCF的治疗依赖于保守措施或手术干预.然而,负压伤口治疗（NPWT）提供了一种有希望的替代方法。该病例研究涉及三名接受喉切除术并发生术后PCF的患者。所有患者均接受改良的抽吸导管和低负压（20-40mmHg）的NPWT。有了NPWT,所有患者均实现伤口完全闭合，愈合时间从两周到六周不等。这表明与传统方法相比，NPWT可以显着加速PCF的愈合。然而,在颈部区域保持气密敷料可能是具有挑战性的。这项研究强调了NPWT在喉切除术后更快地闭合PCF的潜力。需要进一步的研究来优化NPWT应用技术，探索对长期结果的影响，并建立更广泛的临床使用指南。
