Efficacy and safety of cold snare polypectomy for sessile serrated polyps ≥ 10 mm: A systematic review and meta-analysis

BackgroundCold snare polypectomy (CSP) is a promising technique for the removal of sessile serrated polyps (SSPs) ≥ 10 mm. However, the efficacy and safety of this technique remain undetermined.AimsWe aimed to comprehensively evaluate the efficacy and safety of CSP for SSPs ≥ 10 mm.MethodsPubMed, EMBASE, Web of Science and Cochrane Library were searched up to January 2021.ResultsA total of 10 studies consisting of 1727 SSPs (range, 10–40 mm) from 1021 patients were included. The overall rates of technical success, adverse events (AEs) and residual SSPs were 100%, 0.7% and 2.9%, respectively. Subgroup analysis showed that the rates of technical success and AEs were comparable between CSP and cold endoscopic mucosal resection (EMR) (99.9% vs. 100% and 1.3% vs. 0.5%, respectively), between the proximal and distal colon (100% vs. 99.9% and 0.3% vs. 0, respectively), and between polyps of 10–19 mm and ≥20 mm (99.8% vs. 100% and 0.9% vs. 0, respectively). However, subgroup analysis showed that the rate of residual SSPs was slightly lower in CSP compared with cold EMR (1.3% vs. 3.9%), as well as in polyps of 10–19 mm compared with those ≥20 mm (3.1% vs. 4.7%).ConclusionCSP was an effective and safe technique for removing SSPs ≥ 10 mm.

Endoscopic ultrasonography and small‐bowel endoscopy: Present and future

Over the last decade, impressive technological advances have occurred in ultrasonography and small‐bowel endoscopy. Nowadays, endoscopic ultrasonography is an essential diagnostic tool and a therapeutic weapon for pancreatobiliary disorders. Capsule endoscopy and device‐assisted enteroscopy have quickly become the reference standard for the diagnosis of small‐bowel luminal diseases, thereby leading to radical changes in diagnostic and therapeutic pathways. We herein provide an up‐to‐date overview of the latest advances in endoscopic ultrasonography and small‐bowel endoscopy, focusing on the emerging paradigms and technological innovations that might improve clinical practice in the near future.     

Buried Bumper Syndrome: A common complication of levodopa intestinal infusion for Parkinson disease

BackgroundPercutaneous endoscopic gastrostomy (PEG) is required for Levodopa/Carbidopa Intestinal Gel (LCIG) delivery in patients with advanced Parkinson's disease (PD) as well as for enteral feeding in a variety of neurological disorders. Buried Bumper Syndrome (BBS) is a serious complication of PEG. The frequency of BBS in patients receiving LCIG treatment has never been reported.ObjectivesTo compare the frequency of BBS in patients on LCIG treatment or on enteral feeding over the past 12 years and identify possible risk factors.MethodsWe reviewed prospectively recorded data from 2009 to 2020 on two case-series: LCIG-treated PD patients and non-PD patients on enteral nutrition. We identified all BBS incidences. Patients’ characteristics, clinical manifestations, BBS management, possible risk factors and outcomes were analyzed.ResultsDuring the 12 years, 35 PD patients underwent PEG insertion for LCIG infusion, and 123 non-PD patients for nutritional support. There were eight cases of BBS in six PD patients (17.1%). Six of them were effectively managed without treatment discontinuation. Of the enteral feeding patients, only one developed BBS (0.8%) (p < 0.001). We identified inappropriate PEG site aftercare, weight gain, early onset PD, longer survival, treatment duration, dementia and PEG system design as potential risk factors for BBS development.ConclusionsBBS occurs more frequently in LCIG patients than in patients receiving enteral feeding. If detected early, it can be successfully managed, and serious sequalae or treatment discontinuation can be avoided. Regular endoscopic follow-up visits of LCIG-treated patients and increased awareness in patients and clinicians are recommended.     

2016—2021年灌云县手足口病流行病学特征分析

目的 分析灌云县2016—2021年手足口病流行特征,为手足口病的防控提供参考依据。方法 采用描述性统计方法,分析灌云县手足口病的流行特征以及病原学变化等。结果 2016 —2021年灌云县手足口病 4 205例,呈现出“隔年高发”特征,年平均发病率为67.50/10万;4 —6月和10 —12月为高发期;男性占比明显高于女性;0～4岁散居儿童居多;伊山镇、侍庄街道和东王集镇发病率位居前三。2016 —2017年确诊患儿病原以EV71为主,2018—2021年以Cox A6为主。8例重症病例集中在1～5岁,确诊的重症患者以EV71感染为主。结论 灌云县手足口病疫情具有“隔年高发”和季节性“双峰流行”特征,以0～4岁散居儿童为高发人群和灌云县县城及周边镇(街)为高发区域。EV71灭活疫苗接种能有效预防EV71病毒引发的手足口病。     

Challenges in pathological assessment of endoscopic resections

Endoscopic resections (ERs) are performed for early (T1) cancers mostly of the esophagus, stomach and colorectum, offering a minimally invasive and tissue-preserving alternative to traditional surgical resection. Proper preparation and handling of these specimens is key to allow accurate histological assessment of parameters which will dictate the curative, or non-curative, nature of the procedure. Many histological features have been identified which correlate with risk of recurrence and/or nodal metastases, thereby dictating the need for further management. These include histological subtype of the lesion, grade, depth of invasion, margin status, tumor size, lymphovascular invasion and tumor budding [at least in the colon]. This review article will discuss the ideal specimen preparation and discuss each of these histological parameters in turn, as they pertain to the esophagus, stomach and colorectum, highlighting potential caveats and pitfalls to be aware of when reporting these specimens.     

美国胃肠病协会关于急性胰腺炎胰腺坏死处理临床实践专家共识更新解读

美国胃肠病协会（AGA）于2019年8月在Gastroenterology（《胃肠病学》）杂志上发表了针对胰腺坏死处理的临床实践专家共识的更新，归纳并总结了当前的临床证据与专家意见，旨在为胰腺坏死这一复杂临床情况的最佳干预提供指导建议。近年来，随着临床实践的不断深入，急性胰腺炎胰腺坏死的处理经历了较大的变革。从一开始的以手术为主的清创策略过渡到现阶段较为成熟的升阶梯治疗模式。针对胰腺坏死的治疗主要包含两个方面：非手术治疗和有创干预。其中，非手术治疗主要包括抗菌治疗和营养支持等。一旦坏死组织发生感染或无菌性坏死使病人产生显著临床症状，提示有强烈干预指征时，此时更多地依赖于有创干预。升阶梯治疗模式的主要内容为：以经皮引流或透壁内镜引流为首要手段，对于引流无法处理的大量固体坏死，可进行经皮微创或经内镜下坏死清除，若微创手段干预无效可进行开放手术清创。关于选择经皮微创阶梯治疗还是经内镜阶梯治疗，目前尚无研究显示两者之间对病死率等主要临床结局产生影响，不同治疗中心可根据各中心的专业特长和医疗资源，合理选择治疗方案。
