EUS-guided splenic artery embolization for variceal hemorrhage: balancing creativity and innovation in Endo-hepatology with caution
The past decade has seen the development and evolution of Endo-hepatology, an exciting field that represents the intersection between endoscopy and liver disease.1 The refinement of diagnostic tools including EUS-guided liver biopsy, portal pressure gradient measurement, and shear wave elastography as well as therapeutic interventions for gastroesophageal varices have empowered endoscopists to partner with hepatologists to provide comprehensive care for patients with complex liver disease.

EUS-directed transgastric ERCP: Why so on EDGE?
EUS-directed transgastric ERCP (EDGE) has become a viable therapeutic option in patients with Roux-en-Y gastric bypass (RYGB) anatomy, especially in patients with a history of cholecystectomy.1,2 This technique seems to have overcome the suboptimal efficacy of enteroscopy-assisted ERCP and the safety issues concerning laparoscopy-assisted ERCP, respectively.2-5 (Source: Gastrointestinal Endoscopy)

Long-term clinical outcome after endoscopic resection of esophageal squamous cell carcinoma invading the muscularis mucosae without lymphovascular invasion
Lymph node recurrence (LNR) after endoscopic resection (ER) in patients with esophageal squamous cell carcinoma (ESCC) invading the muscularis mucosae (pMM) without lymphovascular invasion (LVI) has been reported as non-negligible in the ER guidelines for esophageal cancer by the Japan Gastroenterological Endoscopy Society. However, these data were not regarded as high-level evidence because several retrospective case series were tabulated without sufficient long-term follow-up. Hence, this guideline stated that the administration of additional treatment after ER could not be determined for this population. (Source: Gastro...

Standardization of EUS imaging and reporting in high-risk individuals of pancreatic adenocarcinoma: consensus statement of the Pancreatic Cancer Early Detection Consortium (PRECEDE)
Pancreatic ductal adenocarcinoma is an aggressive disease most often diagnosed after local progression or metastatic dissemination, precluding resection and resulting in a high mortality rate. For individuals with elevated personal risk of the development of pancreatic cancer, EUS is a frequently used advanced imaging and diagnostic modality. However, there is variability in the expertise and definition of EUS findings among gastroenterologists, as well as lack of standardized reporting of relevant findings at the time of examination.

EUS gastroenterostomy: Why do bad things happen to good procedures?
With the advent of lumen-apposing metal stents (LAMSs), the creation of anastomoses with the use of flexible endoscopes has become a reality. EUS-guided gastroenterostomy (EUS-GE) was first shown to be feasible in animals in 20121 and was described in humans 3 years later.2,3 EUS-GE has become increasingly used throughout the world for the management of gastric outlet obstruction (GOO). Indeed, a recent international, multicenter retrospective study showed EUS-GE to have technical and clinical success rates that rival those of laparoscopic gastroenterostomy (GE) but with a reduction in duration to resumption of oral intake...

Initial multicenter experience using a novel endoscopic tack and suture system for challenging GI defect closure and stent fixation (with video)
Closure of endoscopic resection defects can be achieved with through-the-scope clips, over-the-scope clips or endoscopic suturing. However, these devices are often limited by their inability to close large, irregular, and difficult to reach defects. Thus, we aimed to assess the feasibility and safety of the novel through-the-scope suture-based closure system that was developed to overcome these limitations. (Source: Gastrointestinal Endoscopy)

Near-focus narrow-band imaging for endoscopic assessment of duodenal villi: Making the case more than ever?
Examination of the duodenal mucosa is necessary to rule out, rule in, and monitor various digestive disorders and is a common indication for EGD. Celiac disease (CD), a complex, polygenic, gluten-induced inflammatory enteropathy, is a hallmark example of a disorder wherein duodenal mucosal examination plays a fundamental role  in clinical management. EGD has the benefit of facilitating direct and expedient assessment in this regard, and in CD, several classic endoscopic manifestations may be observed, including mucosal fissuring (ie, “cracked mud appearance”), scalloping or loss of the valvulae conniventes...

Prediction and management of bleeding during endoscopic necrosectomy for pancreatic walled-off necrosis: results of a large retrospective cohort at a tertiary referral center
Lumen-apposing metal stents (LAMSs) provide an endoscopic method for management of walled-off necrosis (WON) and a gateway for the performance of endoscopic necrosectomy (EN). However, bleeding may occur in up to 20% of EN procedures. Predictive factors for bleeding in this patient population are unknown, and there is no agreed-upon algorithm for management of bleeding. The aim of this study was to evaluate preprocedural risk factors for bleeding in patients undergoing endoscopic drainage or EN for WON. (Source: Gastrointestinal Endoscopy)

Applicability, efficacy and safety of over-the-scope clips in children
Over-the-scope clips (OTSCs) are now becoming popular in endoscopy performed in adults for indications such as acute nonvariceal gastrointestinal bleeding, anastomotic bleeding, and for closure of gastrocutaneous and postgastrostomy fistulae. Varied sizes of clip are available but even the smallest, which is 8.5 to 9.8mm in diameter with its loading device on the tip of the endoscope, increases the device and endoscope intubation diameter up to 14.65mm. This may present challenges in terms of the size of the patient in whom it might be used. (Source: Gastrointestinal Endoscopy)
