目的:入口贴片(IP)是胃外部存在的胃柱状上皮。在墨西哥尚未对该病理学进行研究。本研究的目的是确定食管IP的患病率和存在它的患者的临床特征。
方法:进行了一项横断面研究,包括在2015年9月至2016年5月的时间范围内连续接受内窥镜检查的患者。病人回答了一份问卷,并进行了数字色素内镜的高清内镜检查。确定了IP的患病率。卡方检验用于比较出现食管IP的患者和没有食管IP的患者之间的临床特征。
结果:共239例患者纳入研究。他们的平均年龄是53岁,130名(54.4%)是女性。在26例患者中发现IP(10.9%),其中15人为男性(57.7%)。转诊内镜的主要原因是胃食管反流病,69.2%的IP患者和55.9%的无IP患者(p=.19)。最常见的症状是胃灼热和反流。前者存在于有IP的患者的69.2%和无IP的59.1%(p=0.32),后者存在于有IP的患者中的65.4%和无IP的患者中的69.1%(p=.7)。食管外表现分布为:有IP的患者中有46.2%的咳嗽,无IP的患者中有38%的咳嗽(p=.45),有IP的患者中有54%的发音障碍,无IP的患者中有47%的发音障碍(p=.53)。23%的IP患者患有Barrett食管,23%没有IP(p=.99)。
结论:IP的患病率很高。主要转诊诊断为胃食管反流病。有和没有IP的患者在症状或Barrett食管的存在方面没有发现差异。
OBJECTIVE: An inlet patch (IP) is the presence of gastric columnar epithelium outside of the stomach. No studies have been conducted in Mexico on that pathology. The aim of the present study was to determine the prevalence of esophageal IP and the clinical characteristics of the patients that present it.
METHODS: A cross-sectional study was conducted that included consecutive patients referred for endoscopy within the time frame of September 2015 to May 2016. The patients answered a questionnaire, and high-definition endoscopy with digital chromoendoscopy was performed. The prevalence of IP was identified. The chi-square test was used to compare the clinical characteristics between patients that presented with esophageal IP and those without it.
RESULTS: A total of 239 patients were included in the study. Their mean age was 53 years, and 130 (54.4%) were women. IP was found in 26 patients (10.9%), 15 of whom were men (57.7%). The main reason for referral to endoscopy was gastroesophageal reflux disease, present in 69.2% of the patients with IP and in 55.9% without IP (p=.19). The most common symptoms were heartburn and regurgitation. The former was present in 69.2% of the patients with IP and in 59.1% without IP (p=.32), and the latter was present in 65.4% of the patients with IP and 69.1% without IP (p=.7). Extraesophageal manifestation distribution was: cough in 46.2% of the patients with IP and 38% without IP (p=.45) and dysphonia in 54% with IP and 47% without IP (p=.53). Twenty-three percent of the patients with IP had Barrett\'s esophagus, as did 23% without IP (p=.99).
CONCLUSIONS: The prevalence of IP was high. The primary referral diagnosis was gastroesophageal reflux disease. No differences were found in relation to symptoms or the presence of Barrett\'s esophagus between the patients with and without IP.
