A duodenal periampullary diverticulum can cause changes in the local anatomy and pose a challenge for the cannulation of the bile duct. Cannulation may be much more difficult if the ampulla is located within the diverticula. We present the case of a 40-year-old man who developed obstructive jaundice and cholangitis because of the duodenal diverticula mechanically obstructing the common bile duct (Lemmel's syndrome). The papilla was located entirely within the duodenal diverticula and was brought out after placing endoscopic variceal ligation (EVL) bands. Biliary access and stenting could be done easily, after exposing the papilla. There were no complications during the procedure or the recovery period.
十二指肠壶腹周围憩室会引起局部解剖结构的变化,并对胆管插管构成挑战。如果壶腹位于憩室内,插管可能会更加困难。我们报告了一例40岁的男性,他因十二指肠憩室机械性阻塞总胆管而患上梗阻性黄疸和胆管炎(Lemmel综合征)。乳头完全位于十二指肠憩室内,在放置内镜下静脉曲张结扎带(EVL)后取出。暴露乳头后,可以很容易地进行胆道入路和支架植入。在手术或恢复期内没有出现并发症。

Background and Study Aims In the coronavirus disease 2019 (COVID-19) pandemic, patients undergoing esophagogastroduodenoscopy (EGD) and colonoscopy on the same day (bidirectional endoscopy [BDE]) have increased. The aims of the study were to compare the procedure times, benefits, and safety of same-day BDE and conventional serial endoscopic examination (SEE). Patients and Methods All the patients undergoing evaluation with either BDE or SEE were prospectively enrolled at Ramaiah Medical College and Hospitals, Bangalore, from 1st December 2020 to 31st May 2021. EGD was immediately followed by colonoscopy in BDE. In SEE, EGD was followed by colonoscopy in 1 or 2 days. Clinical data and results were collected and evaluated. Results Two hundred consecutive patients who consented for BDE were enrolled in the study. The mean ± standard deviation (range) age of the patients was 45 ± 14.5 (22-60) years. Majority (124 [62%]) were men. The outcome measures of Boston Bowel Preparation Scale with the excellent/good preparation score and polyp detection rate were similar in both groups (p = 0.4). The total procedure time was significantly higher in the SEE group than in the BDE (p < 0.001). There were no adverse events noted in the study. The overall patient experience and satisfaction were higher in BDE than in SEE without any difference in the quality of the procedures (p < 0.001). Patients with weight loss and anemia were more likely to have a positive test result than the patients with abdominal pain and diarrhea. Conclusions In conclusion, same-day BDE is advised for patients with anemia and weight loss which can reduce the number of hospital visits and improve patient satisfaction in COVID times.
背景与研究目的在2019冠状病毒病(COVID-19)大流行中,同一天接受食管胃十二指肠镜(EGD)和结肠镜检查(双向内镜[BDE])的患者有所增加。该研究的目的是比较当日BDE和常规连续内镜检查(SEE)的手术时间、益处和安全性。患者和方法所有接受BDE或SEE评估的患者于2020年12月1日至2021年5月31日在班加罗尔Ramaiah医学院和医院前瞻性纳入。BDE患者立即行EGD后结肠镜检查。在SEE患者中,EGD术后1或2天进行结肠镜检查。收集并评价临床资料和结果。结果连续200名同意BDE的患者入组研究。患者平均±标准差(范围)年龄为45±14.5(22-60)岁。大多数(124例[62%])是男性。波士顿肠准备量表的优等/良好准备评分和息肉检出率两组的结局指标相似(p = 0.4)。SEE组的总手术时间明显高于BDE组(p < 0.001)。研究中没有发现不良事件。BDE的总体患者体验和满意度高于SEE,但手术质量没有任何差异(p < 0.001)。体重减轻和贫血的患者比腹痛和腹泻的患者更容易出现阳性检测结果。结论建议贫血和体重减轻患者当日行BDE,可减少患者就诊次数,提高患者对新冠肺炎的满意度。

Surgical necrosectomy has been the traditional management for pancreatic necrosis and is done using blunt dissection. However, lack of dedicated endoscopic accessories has been a major limitation in direct endoscopic necrosectomy (DEN). Standard endoscopic accessories cannot effectively remove large necrotic material. Also, diameter of instrument channel of the endoscope limits the ability to use large-diameter graspers that can remove large chunks of necrotic material. In this news, we discuss a recent study that has evaluated a new powered endoscopic debridement system for DEN.
外科坏死切除术是胰腺坏死的传统治疗方法,采用钝性解剖。然而,缺乏专用的内窥镜附件一直是直接内窥镜尸检(DEN)的主要限制。标准的内窥镜附件不能有效去除大块坏死物质。此外,内窥镜的器械通道的直径限制了使用能够去除大块坏死物质的大直径抓取器的能力。在这篇新闻中,我们讨论了最近的一项研究,该研究评估了一种用于DEN的新型动力内镜清创系统。

Management of infected lesser sac walled-off pancreatic necrosis (WOPN) is technically challenging and involves endoscopic ultrasound (EUS)-guided transmural drainage using either lumen-apposing metal stent (LAMS) or multiple plastic stents as the standard approach. A step-up approach—drainage followed by additional direct endoscopic necrosectomy (DEN) whenever required—has been a standard recommendation. Collections extending to the paracolic gutter are difficult to manage endoscopically and often require additional surgical intervention. In this video case, we describe a combined approach using EUS-guided LAMS and percutaneous fully covered self-expandable metal stent-guided DEN (e-DEN + p-DEN) for successful management of an infected lesser sac WOPN with paracolic extension.
治疗受感染的小囊壁性胰腺坏死(WOPN)在技术上具有挑战性,需要内镜超声(EUS)引导下的跨壁引流,使用腔内金属支架(LAMS)或多个塑料支架作为标准方法。升级入路-引流后,在需要时进行直接内镜下坏死切除术(DEN) -已成为标准推荐。延伸到结肠旁沟的积液很难在内镜下处理,通常需要额外的手术干预。在这个视频病例中,我们描述了一种联合方法,使用eus引导的LAMS和经皮全覆盖自膨胀金属支架引导的DEN (e-DEN + p-DEN)成功治疗了感染的小囊性WOPN伴结肠旁延伸。

Gastroesophageal Reflux after Peroral Endoscopic Myotomy: Myth or Reality? 经口内镜肌切开术后胃食管反流:神话还是现实?

Peroral endoscopic myotomy (POEM) is an accepted treatment for achalasia cardia (AC), and results are comparable to those of laparoscopic Heller myotomy (LHM). In recent years, several reports have confirmed higher incidence of gastroesophageal reflux (GER) following POEM. This review evaluates the current evidence regarding post-POEM GER, critically examines the potential contributing factors responsible for GER, limitations of the current available functional testing, and precautions and preventive measures, and provides future directions for research. Factors conclusively contributing to increased post-POEM GER include injury to the sling fibers of the lower esophageal sphincter, length of gastric myotomy > 2 cm, and others. Historically, these same factors have been implicated for development of GER after surgical (laparoscopic) myotomy. Although less invasive, optimal technique of POEM may be important to control post-POEM GER. Most post-POEM GER occurs during the immediate post-POEM period, is mild, and is easily treatable using proton-pump inhibitors. GER incidence plateaus at 2 years and is comparable to that after LHM. Patients should therefore be prescribed proton-pump inhibitors for at least 2 years. Antireflux procedures (ARPs) are infrequently required in these patients as the incidence of refractory GER is low. Novel ARPs have been recently described and are currently under evaluation. Conclusive diagnosis of GER is a clinical challenge. Most patients are asymptomatic, and GER is diagnosed only on abnormal esophageal acid exposure (EAE). Studies have demonstrated that current measures to diagnose GER are inadequate, inaccurate, and cannot differentiate between true GER and abnormal EAE due to food fermentation in the distal esophagus. The Lyon Consensus criteria should be implemented for confirmation of diagnosis of GER. Finally, the review recommends an evidence-based clinical algorithm for evaluation and management of post-POEM GER and provides guidelines for future research in this field.
经口内窥镜肌切开术(POEM)是贲门失弛缓症(AC)公认的治疗方法,其结果与腹腔镜Heller肌切开术(LHM)相当。近年来,一些报道证实了POEM术后胃食管反流(GER)的发生率较高。本文评估了目前有关poem后GER的证据,批判性地探讨了可能导致GER的因素,当前可用功能测试的局限性,预防措施和预防措施,并为未来的研究方向提供了建议。导致poem后GER增加的决定性因素包括食管下括约肌悬吊纤维损伤、胃肌切开术长度约为2 cm等。从历史上看,这些相同的因素与手术(腹腔镜)肌切开术后GER的发展有关。虽然微创性较小,但最佳的POEM技术对于控制POEM后GER可能很重要。大多数poem后GER发生在poem后,症状轻微,使用质子泵抑制剂很容易治疗。GER的发病率在2年后趋于平稳,与LHM后的发病率相当。因此,患者应服用质子泵抑制剂至少2年。这些患者很少需要抗反流手术(ARPs),因为难治性GER的发生率很低。最近有新的ARPs被描述,目前正在评估中。GER的结论性诊断是一项临床挑战。大多数患者无症状,只有在异常食管酸暴露(EAE)时才能诊断出GER。研究表明,目前诊断GER的措施是不充分的,不准确的,并且不能区分真正的GER和由于食管远端食物发酵而导致的异常EAE。在确诊GER时应遵循里昂共识标准。最后,本综述推荐了一种基于证据的临床算法来评估和管理poem后GER,并为该领域的未来研究提供了指导。

Esophageal Motility Disorders: Are We Missing in Our Busy Endoscopy Practice? 食道运动障碍:在繁忙的内窥镜检查中我们会错过吗?

Esophageal motility disorders (EMDs) form a significant part of a busy endoscopist's practice. Endoscopy plays an all-encompassing role in the diagnosis and management of EMDs including achalasia cardia. The focus on in-vogue third-space endoscopic procedures such as per-oral endoscopic myotomy often digresses the important role of endoscopy. Endoscopic evaluation forms the part of standard first-line evaluation of any dysphagia and serves to rule out a secondary cause such as an esophagogastric junction malignancy and eosinophilic esophagitis. Moreover, endoscopic evaluation may itself provide corroborative evidence that may contribute to the diagnosis of the motility disorder. Achalasia cardia may present with a wide spectrum of endoscopic findings from being entirely normal and the well-known and pathognomonic dilated sigmoid-shaped esophagus with food residue, to lesser-known ornate signs. The evidence on the role of endosonography in EMDs is conflicting and largely restricted to evaluation of pseudoachalasia. High-resolution manometry (HRM) remains the gold standard in the diagnosis of EMDs. Endoscopists must also keep abreast of the latest iteration of the Chicago classification version 4.0, which differs significantly from its predecessor in being more stringent in making diagnosis of esophagogastric junction outflow obstruction and disorders of peristalsis since these manometric findings may be seen in normal individuals and may be mimicked by opioid use and gastroesophageal reflux. The latest rendition also includes the use of provocative maneuvers and testing in both supine and sitting posture. Despite being the gold standard, there are certain lacunae in the use and interpretation of the Chicago classification of which the users should be well aware. Emerging technologies such as functional lumen imaging probe and planimetry, and timed barium esophagogram fill the lacuna in diagnosis of these motility disorders, which at times is beyond the resolution of HRM.
食道运动障碍(EMD)是繁忙的内镜医生实践的重要组成部分。内镜在包括贲门失弛缓症在内的EMD的诊断和治疗中发挥着包罗万象的作用。对流行的第三空间内窥镜手术的关注,如口腔内窥镜肌切开术,往往偏离了内窥镜的重要作用。内镜评估是任何吞咽困难的标准一线评估的一部分,用于排除次要原因,如食管胃交界处恶性肿瘤和嗜酸性食管炎。此外,内窥镜评估本身可能提供有助于运动障碍诊断的确证。贲门失弛缓症可能表现出广泛的内镜检查结果,从完全正常和众所周知的、具有食物残渣的扩张性乙状食管到鲜为人知的华丽体征。关于内镜检查在EMD中的作用的证据是相互矛盾的,并且主要局限于评估假性贲门失弛缓症。高分辨率测压(HRM)仍然是诊断EMD的金标准。内窥镜医生还必须跟上芝加哥分类4.0版本的最新迭代,其与前代的显著不同之处在于对食管-胃交界处流出道梗阻和蠕动障碍的诊断更加严格,因为这些测压结果可以在正常个体中看到,并且可以通过阿片类药物的使用和胃食管反流来模仿。最新的表演还包括在仰卧和坐姿中使用挑衅性动作和测试。尽管芝加哥分类法是黄金标准,但在使用和解释芝加哥分类法时仍存在一些缺陷,用户应该清楚这一点。新兴技术,如功能性管腔成像探针和平面测量法,以及定时钡食管造影术,填补了诊断这些运动障碍的空白,这些障碍有时超出了HRM的分辨率。

A 29-year-old man presented with shortness of breath associated with abdominal pain and distension of 2 weeks’ duration. He was diagnosed with alcohol-related acute necrotizing pancreatitis 4 months ago, and computed tomography (CT) done at 3 months of illness revealed a 2.5-cm collection in the neck of the pancreas with dilated upstream main pancreatic duct, suggesting a diagnosis of disconnected pancreatic duct. The investigations done during the current admission revealed hypoxia with amylase-rich exudative ascites (►Fig. 1A) and a large acute pseudocyst (AP) (►Fig. 1B). He underwent endoscopic ultrasound–guided transmural drainage of AP with a fully covered, self-expandable biflanged metal stent (BFMS) (►Fig. 1C). Post drainage, the patient had marked improvement in symptoms but developed palpable subcutaneous emphysema in the neck. CT chest revealed pneumomediastinum (►Fig. 2A; arrows) and CT abdomen revealedmarked reduction in the size of AP, resolution of ascites, and pneumoperitoneum (►Fig. 2B; arrows) along with pneumoretroperitoneum. The patient was treated with intravenous antibiotics, oxygen supplementation, and nasojejunal enteral feeding.

Background Patients with gastrointestinal (GI) symptoms in remote areas do not have access to standard medical care with the issues related to cost of medical care, transportation, health literacy, lack of healthcare insurance—all preventing healthcare access in a timely manner. To overcome this, we designed a mobile endoscopy van with the intent to provide free essential medical services to the rural population. Methods This is a retrospective study of patients with predominantly upper GI symptoms at two community health centers (each 2 days camp). This is an audit of endoscopy findings in a community set up using a Mobile Endoscopy Unit (MEU). Patients' details were collected in a pre-designed questionnaire. Only those patients with alarm symptoms and suspicion of any pathological state underwent esophagogastroduodenoscopy (EGD) in MEU. Data analysis was done using descriptive statistics. Results A total of 724 patients (424 [58.5%] males; mean [SD] age 48.5 [5.2] years) were included. The commonest presenting symptom was heartburn in 377 (52.1%) patients. The median duration of symptoms was 6.5 (range: 2–36) months. Gastroesophageal reflux disease was seen in 16 (6.8%) patients, ulceroproliferative growth was noted in the stomach in 3 (1.3%) patients. Eighteen (7.6%) patients had a positive rapid urease test and received Helicobacter pylori eradication therapy. The most commonly prescribed drugs were proton-pump inhibitors in 692 (95.6%) patients. Nine (1.2%) patients had chronic liver disease secondary to alcoholism and were counseled for abstinence. All procedures were safely performed without any immediate adverse events. Conclusions Community outreach strategies such as the use of mobile endoscopy unit were found to be very useful in the diagnosis of GI symptoms. More research is needed in low-income countries to treat complex pathological states in rural patients.
背景:由于医疗费用、交通、健康素养、缺乏医疗保险等问题,偏远地区的胃肠道(GI)症状患者无法获得标准的医疗服务,这些问题都阻碍了他们及时获得医疗服务。为了克服这一问题,我们设计了一辆移动内窥镜检查车,旨在为农村人口提供免费的基本医疗服务。方法对两个社区卫生中心(每个2天营)以上消化道症状为主的患者进行回顾性研究。这是对使用移动内窥镜检查装置(MEU)的社区内窥镜检查结果的审计。患者的详细信息收集在预先设计的问卷中。在MEU中,只有那些有警示症状和怀疑有任何病理状态的患者才行食管胃十二指肠镜检查。数据分析采用描述性统计。结果共724例患者,其中男性424例,占58.5%;平均[SD]年龄48.5[5.2]岁)。377例(52.1%)患者最常见的症状为胃灼热。中位症状持续时间为6.5个月(范围:2-36个月)。胃食管反流病16例(6.8%),胃溃疡增生性生长3例(1.3%)。18例(7.6%)患者快速脲酶试验阳性并接受幽门螺杆菌根除治疗。692例(95.6%)患者最常使用的处方药是质子泵抑制剂。9例(1.2%)患者有继发于酒精中毒的慢性肝病,并被建议戒酒。所有的手术都是安全的,没有任何直接的不良事件。结论社区外展策略,如使用移动内窥镜检查装置,对胃肠道症状的诊断非常有用。低收入国家需要更多的研究来治疗农村患者的复杂病理状态。

The field of endoscopic ultrasound (EUS) has evolved significantly over the last two decades from being a tool of only diagnostic purpose to tissue acquisition and now therapeutic potential. There have been several important publications in the field of EUS in the last few years, which had a major impact in the clinical management of various gastrointestinal disorders. In this review, we discuss four such articles that in our opinion will significantly impact the role of EUS in treating various conditions. The first article is a randomized controlled trial comparing EUS-guided gall bladder drainage with percutaneous gall bladder drainage for high-risk acute cholecystitis. The second article is a randomized controlled trial comparing EUS versus minimally invasive surgery for necrotizing pancreatitis. The third article is a novel human study of EUS-guided portal pressure measurement in patients with portal hypertension. The last article is also a randomized controlled trial evaluating the role of rapid on-site evaluation for EUS-guided fine needle biopsy in solid pancreatic lesions.
在过去的二十年里,内窥镜超声(EUS)领域已经从一种仅用于诊断的工具发展到组织采集,现在具有治疗潜力。在过去的几年里,EUS领域有几篇重要的出版物,对各种胃肠道疾病的临床管理产生了重大影响。在这篇综述中,我们讨论了四篇这样的文章,我们认为这些文章将对EUS在治疗各种疾病中的作用产生重大影响。第一篇文章是一项随机对照试验,比较EUS引导下胆囊引流术和经皮胆囊引流术治疗高危急性胆囊炎。第二篇文章是一项比较EUS和微创手术治疗坏死性胰腺炎的随机对照试验。第三篇文章是一项关于EUS引导下门静脉高压患者门静脉压力测量的新的人体研究。最后一篇文章也是一项随机对照试验,评估EUS引导下细针活检在胰腺实性病变中的快速现场评估作用。
