意大利帕多瓦大學Edoardo?V.?Savarino教授 胃食管反流?。℅ERD)是西方國家中最常見的慢性胃腸道疾病之一,該病因廣泛流行、臨床表現變化多樣、尚未被識別的發(fā)病率以及巨大的經濟花費而引起廣泛關注??狗置谥委?,尤其是質子泵抑制劑(PPIs)是目前治療的主要方式,因為這類藥物在消除反流癥狀、治療食管黏膜損傷方面效果明顯。目前,有GERD癥狀(如燒心和/或反流)的患者首先接受4~8周的PPI試驗性治療,治療期間,患者必須在早餐前服用PPI藥物。若患者對治療無反應(見于高達40%的患者),醫(yī)生需首先確認患者的依從性,核實患者是在推薦時間服用了恰當的PPI劑量,然后更換為第二代PPI進行治療,或者將PPI服用頻率改為每日2次。如果癥狀仍然存在,并且不存在報警癥狀(否則須強制行內鏡檢查),這種情況下有必要進行診斷檢查。 事實上,當GERD患者對內科藥物治療(8~12周PPI治療每日1次或2次)或外科治療無效時,或者懷疑存在并發(fā)癥(難治性糜爛性食管炎、食管狹窄、Barrett食管)時,或者考慮改變治療方案之前必須進行確診時,必須進行診斷評價。然而,記錄GERD患者反流的作用可能是一個挑戰(zhàn)。事實上,內鏡檢查有一定的局限性,因為大部分患者鏡下的表現是正常的。而且,上消化道內鏡檢查時食管活檢的組織學評估還有一些弊端。因此,大多數情況下,我們主要致力于發(fā)現異常的胃食管反流。 2014年,應用于臨床實踐的發(fā)現胃食管反流證據的技術主要有兩種:無線pH測量法和聯合阻抗pH測量法。 Bravo pH監(jiān)測系統(tǒng)使用一個無線電遙測的pH傳感膠囊,行上消化道內鏡檢查時可以將此膠囊放置于食管遠端黏膜處,一般放置于鱗柱狀上皮交界以上6cm處(不使用經鼻內鏡時放置在9cm處)。這個膠囊是橢圓形的,長度為25mm,可以測量pH變化,通過射頻信號將數據傳遞到夾在患者腰帶的接收器上,接收器大小與傳呼機一樣。多項對照試驗研究已經證實了這種無導管的無線電pH電極可用于測量食管酸暴露。這種監(jiān)測系統(tǒng)的主要優(yōu)勢在于,相較與導管pH測量法患者的耐受性更好,這種方法也增加了將膠囊固定于不同位置的可能。然而,此法也有許多弊端。單一傳感器可能會將吞咽事件也進行測量從而導致對反流的評價過度,膠囊過早脫落也會引起監(jiān)測結果變化,需要重復放置。而且,對于主訴有嚴重胸痛(5%),吞咽痛,或者膠囊無法脫落的患者需要行額外的內鏡檢查。因此,無線電pH監(jiān)測系統(tǒng)是一種經過驗證的可作為導管pH監(jiān)測法的替代方法,對于不能耐受導管放置的患者或者需要長期進行pH監(jiān)測的患者(例如癥狀一整天較少發(fā)作的患者,像非心源性胸痛)來說可能是十分有用的。 聯合多通道腔內電阻抗及pH(MII-pH)通過測量與導管伴行的電阻抗的方向(逆行食團運動)和范圍(食管下端括約肌以上至多17cm)變化檢測反流,從而根據相關的pH變化來判定反流屬于酸性(pH4.0)。與電阻抗監(jiān)測系統(tǒng)相比,利用導管法測pH弊端很大。主要表現在電阻抗檢測非酸性反流方面。因此,隨著這項技術的應用,臨床醫(yī)生可以將更多的反流癥狀與反流事件相關聯。這將會提高GERD的診斷率,單一pH測量會導致GERD的過低評估和功能性燒心的過度評估。但是,這種測量方法也有缺點。反流事件精確度的確認需要人工分析,因此這種技術比傳統(tǒng)的全自動化pH測試需要花費更多時間。而且,在糜爛性食管炎,或者Barrett’s食管,或者重度動力異常疾病中,往往出現低基線電阻抗,會使電阻抗-pH追蹤的分析更加費力。最后,將反流癥狀與反流事件關聯起來的實際指數(癥狀指數SI和癥狀相關可能性SAP)有許多局限性,需要以后的結果對照研究來明確它們的效用。盡管存在這些缺點,MII-pH監(jiān)測系統(tǒng)目前被認為是檢測反流事件和評價難治性GERD內科或外科治療效果的金標準。 反流監(jiān)測能夠進一步描述難治性患者的特性,因為研究可能會發(fā)現: PPI治療失敗,酸反流持續(xù)存在時,需要升級治療或手術來控制胃酸反流。 酸性反流已被充分控制,但是非酸性反流癥狀仍持續(xù)存在時,需要求助于特異治療(短效食管下端括約肌松弛抑制劑、手術、選擇性5-羥色胺再攝取抑制劑或5-羥色胺-去甲腎上腺素再攝取抑制劑等抗抑郁藥)。 根本無反流存在。在難治性GERD患者中,反流監(jiān)測系統(tǒng)顯示陰性,這些患者的燒心癥狀被歸類為“功能性燒心”,那些食管外的癥狀(哮喘、咳嗽、喉炎)需要額外的或重復的診斷檢查來明確非GERD病因(肺部、過敏、耳鼻喉)。 有兩點需要考慮:①反流監(jiān)測應在PPI治療時或非治療時實施;②應用什么技術(導管pH監(jiān)測、無線電pH監(jiān)測、電阻抗pH監(jiān)測)。未治療時進行反流監(jiān)測可以應用任何可行的技術(無線電或電阻抗pH)。如果檢測結果為陰性(食管遠端酸暴露正常,陰性癥狀-反流相關性),患者很有可能不是GERD,PPIs治療應當中止,需要調查非GERD病因。但是,如果檢測結果是陽性的,并不能表示PPI治療失敗。治療時進行反流檢測應使用電阻抗pH監(jiān)測系統(tǒng),因為它能測量非酸性反流。電阻抗pH檢測可以檢測出所有可能的情況:持續(xù)性酸性反流、持續(xù)性非酸性反流、無反流。目前為止,電阻抗pH檢測結果陰性強烈表示癥狀并不與反流相關。在難治性GERD患者,比較治療存在與否時反流檢測的診斷率的研究十分有限,而且結果并不統(tǒng)一。因此,最近的指南建議是否在PPI治療時進行檢測,應依賴GERD的預測可能性和需要解決的問題。GERD可能性很低的患者(例如,非典型臨床表現,無相應典型GERD癥狀),pH監(jiān)測最好在非治療期間實施,因為這樣可以排除GERD。GERD可能性高的患者(典型癥狀,至少對PPI部分有效,之前內鏡檢查或pH檢測結果為陽性),在治療期間進行反流監(jiān)測可以找尋PPI治療時仍存在的持續(xù)性反流。手術之前進行GERD評估,反流監(jiān)測最好在無PPI治療時進行,以便確認GERD的存在。 目前數據資料有限,關于難治性GERD患者pH測試方法的選擇尚無明確的共識。檢測方法的選擇可能取決于患者的臨床表現,GERD的預期可能性,以及技術和專業(yè)知識的可行性。 Gastroesophageal reflux disease (GERD) is one of the most common chronic gastrointestinal diseases in Western countries, notable for its prevalence, variety of clinical presentations, under-recognized morbidity, and substantial economic consequences.1?The use of anti-secretory therapy, in particular proton pump inhibitors (PPIs), represents the mainstay of its treatment given the high efficacy of these drugs in relieving reflux symptoms and healing esophageal mucosal damages. At present, patients who have GERD symptoms (ie, heartburn and/or acid regurgitation) are given a 4- to 8-week trial with a PPI to be taken in the morning before breakfast. In case of lack of response (in up to 40% of patients), the physician should confirm patient compliance, check that the patient is taking the PPI dose at the recommended time, switch to a second-generation PPI, or administer a twice-daily PPI. If symptoms still persist and alarm signs are absent (otherwise endoscopy is mandatory), a diagnostic work-up is necessary. Indeed, diagnostic evaluation in patients with GERD symptoms is typically required when patients do not respond to medical (8- to 12-week trial with a PPI given once or twice daily) or surgical therapy, complications are suspected (refractory erosive esophagitis, stenosis, Barrett’s esophagus), or the diagnosis must be confirmed before a change in treatment strategy.However, documenting the role of reflux in GERD symptoms may be challenging. Indeed, endoscopy has several limitations given that the majority of patients have a normal endoscopic findings. Moreover, histologic assessment on esophageal biopsies taken during upper endoscopy present few drawbacks. Therefore, in most cases, our efforts are focused on documenting an abnormal gastroesophageal reflux. In 2014, two different techniques are mainly used in clinical practice in order to document gastroesophageal reflux: wireless pH-metry and combined impedance-pH testing. The Bravo pH monitoring?system uses a radiotelemetry pH sensing capsule that is attached during upper endoscopy to the mucosa of the distal esophagus, commonly at 6 cm above the squamocolumnar junction (at 9 cm if a transnasal endoscopy-free approach is used). The oblong capsule is 25 mm in length and measures pH changes, thus transmitting data via a radiofrequency signal to a pager-sized receiver clipped onto the patient’s belt. The performance of the catheter-free wireless pH electrode in measuring esophageal acid exposure has been proven in several controlled trials. The main advantages of this system are the lack of a catheter with increasing tolerability when compared with catheter-based pH monitoring and the possibility of fixing the capsule in different positions.11?However, there are some drawbacks to note. A single sensor may overestimate reflux by including swallow events, and early detachment can also alter results and may require repeated placement. Furthermore, additional endoscopic procedures may be required for patients who report severe chest pain (5%), odynophagia, or failure of the capsule to detach.?Thus, wireless pH monitoring is a validated alternative to catheter-based pH monitoring and may be very helpful in patients who do not tolerate catheter placement or in whom longer-duration pH monitoring is required (for instance, in patients with symptoms less frequently reported during a single day, such as non-cardiac chest-pain). Combined multichannel intraluminal impedance and pH (MII-pH)?detects reflux by measuring the direction (retrograde bolus movement) and extent (up to 17 cm above the lower esophageal sphincter) of changes in impedance along a catheter and qualifies reflux as acid (if pH < 4.0) or nonacid (if pH >4.0) based on the concomitant pH changes. Compared with impedance monitoring, detection of reflux with catheter-based pH monitoring is clearly inferior. This is mainly related to the impedance detection of nonacid reflux. Therefore, with the use of this technique, the clinician can correlate an increased number of reflux symptoms with a reflux episode. This increases the diagnostic yield in patients with GERD and shows that the use of pH-metry alone will result in an underestimation of GERD and an overestimation of functional heartburn. However, there are some limitations to mention. Accuracy of reflux episodes identification requires manual analysis and therefore more time than does the fully automated conventional pH test. Moreover, low baseline impedance, common in patients with erosive esophagitis or Barrett’s esophagus or with severe motility disorders, can make analyzing impedance-pH tracings arduous. Finally, the actual indices used to correlate symptoms to reflux episodes (the symptom index [SI] and the symptom association probability [SAP]) present some limitations that highlight the need for future controlled outcome studies to address their validity.Thus, despite these limitations, MII-pH monitoring is currently recognized as the gold standard for the detection of reflux episodes and for the evaluation of patients with symptoms refractory to medical or surgical treatment< Reflux monitoring enables further characterization of the refractory patient, as the study may reveal: PPI failure with ongoing acid reflux, which will require escalation of therapy to control acid reflux or surgery. Adequate acid control but ongoing symptomatic nonacid reflux, which may respond to specific therapy (transient lower esophageal sphincter relaxation inhibitors, surgery, antidepressants [selective serotonin reuptake inhibitors, serotonin–norepinephrine reuptake inhibitors]). No reflux at all. Among refractory GERD patients with a negative reflux monitoring study, those with heartburn may be classified as having “functional heartburn,” while those with extra-esophageal symptoms (asthma, cough, laryngitis) will need additional or repeat work-up for non-GERD (pulmonary, allergic, ENT) etiologies. Two key issues are relevant to consider: 1) performing reflux monitoring on or off PPI therapy and 2) what technique to use (catheter-based pH, wireless pH, or impedance pH). Reflux testing off therapy can be performed with any of the available techniques (wireless pH or impedance pH). If the test is negative (normal distal esophageal acid exposure and a negative symptom–reflux association), GERD is very unlikely, PPIs can be discontinued, and non-GERD etiologies should be investigated. However, if the test is positive, it does not provide insight about the PPI failure. Reflux testing on therapy should be performed with impedance-pH monitoring to enable measurement of nonacid reflux. Impedance-pH testing may reveal all possible scenarios: ongoing acid reflux, ongoing nonacid reflux, or no reflux. So far, a negative impedance-pH test on medication strongly supports that the symptoms are not related to reflux. Studies comparing the yield of “ off vs on” therapy reflux monitoring in refractory GERD patients are limited and have provided opposing results.19,20? Recent guidelines therefore suggest that the choice of on PPI or off PPI should rely on the pretest probability of GERD and the question that needs to be answered. In patients with a low likelihood of GERD (for instance, atypical presentations without concomitant typical GERD symptoms) pH monitoring off medication may be preferred as it will enable ruling out GERD.
