Vocal nodules and polyps are two common noninfectious causes of hoarseness. Patients with persistent hoarseness often require microscopic laryngeal surgery to excise mass lesions of the larynx despite extensive voice resting and modification of voice use behavior. Helicobacter pylori has recently been reported to present in the upper aerodigestive tract. This study applies the rapid urease test to determine the colonization of Helicobacter pylori in surgical specimens of patients with vocal nodules and polyps.
In this prospective study, 53 consecutive patients with vocal nodules (n = 20) or vocal polyps (n = 33) were investigated from November 2004 to July 2005. Microscopic laryngeal surgery was performed in all cases. Tissue specimens harvested from the larynx were analyzed using the rapid urease test.
The study population consisted of 33 females and 20 males with a mean age of 43.1 +/- 9.9 years. Thirteen (24.5%) of the 53 patients revealed Helicobacter pylori colonization, and all were histopathologically diagnosed with vocal polyps. The difference in incidence of Helicobacter pylori colonization between vocal nodules and vocal polyps was statistically significant (0% [0/20] vs. 39.4% [13/33], P = .001).
Helicobacter pylori often colonizes in the larynxes of patients with vocal polyps. These results indicate the involvement of Helicobacter pylori in vocal polyps. However, the presence of Helicobacter pylori as an etiologic factor in vocal polyps remains inconclusive.
声带小结和息肉是导致声音嘶哑的两种常见非感染性病因。尽管患者长时间禁声并改变发声行为,但持续性声音嘶哑的患者通常仍需要进行显微喉镜手术来切除喉部的肿物病变。最近有报道称幽门螺杆菌存在于上呼吸道消化道。本研究应用快速尿素酶试验来确定声带小结和息肉患者手术标本中幽门螺杆菌的定植情况。
在这项前瞻性研究中,于2004年11月至2005年7月对53例连续的声带小结患者(n = 20)或声带息肉患者(n = 33)进行了调查。所有病例均接受了显微喉镜手术。使用快速尿素酶试验对从喉部采集的组织标本进行分析。
研究人群包括33名女性和20名男性,平均年龄为43.1±9.9岁。53例患者中有13例(24.5%)显示幽门螺杆菌定植,且所有患者经组织病理学诊断为声带息肉。声带小结和声带息肉患者幽门螺杆菌定植发生率的差异具有统计学意义(0%[0/20]对39.4%[13/33],P = .001)。
幽门螺杆菌常定植于声带息肉患者的喉部。这些结果表明幽门螺杆菌与声带息肉有关。然而,幽门螺杆菌作为声带息肉病因的存在仍无定论。
