Multisegmented esophageal fully covered self-expandable metal stent for palliation of malignant dysphagia: a prospective multicenter feasibility and safety study.

BACKGROUND AND AIMS: A novel multisegmented esophageal fully covered self-expandable metal stent (FCSEMS) was designed to reduce stent migration that is seen in up to 30% of patients. We aimed to evaluate safety and efficacy of this multisegmented FCSEMS. METHODS: This multicenter prospective study aimed to include 30 patients undergoing palliative stent placement. Efficacy defined as technically successful stent placement and dysphagia scores and safety defined as (serious) adverse events ((S)AEs) were measured. RESULTS: The study was prematurely terminated due to safety concerns after including 23 patients (mean age 72 yrs (± 10); 78% male). Stent placement was technically successful in 21 patients (91%) and dysphagia scores had improved in all patients with successful stent placement. SAEs occurred in 16 (70%) patients. Stent-related mortality occurred in three patients (13%). CONCLUSION: The multisegmented FCSEMS successfully treated malignant dysphagia. The study was however prematurely terminated because stent placement was associated with a relatively high SAE rate. (Clinical trial registration number: NCT04415463).

Best Practices in Esophageal, Gastroduodenal, and Colonic Stenting.

Endoscopic stenting is an area of endoscopy that has witnessed noteworthy advancements over the last decade, resulting in evolving clinical practices among gastroenterologists around the world. Indications for endoscopic stenting have progressively expanded, becoming a frequent part of the management algorithm for various benign and malignant conditions of the gastrointestinal tract, from esophagus to rectum. In addition to expanded indications, continuous technological enhancements and development of novel endoscopic stents have resulted in an increased success of these approaches and, in some cases, allowed new applications. This review aimed to summarize best practices in esophageal, gastroduodenal, and colonic stenting.

A colocação de próteses endoscópicas é uma técnica que tem testemunhado avanços notáveis na última década, resultando na evolução da prática clínica diária dos gastroenterologistas em todo o mundo. As indicações para a colocação de próteses endoscópicas têm expandido progressivamente, tornando-se uma opção cada vez mais frequente no algoritmo de abordagem das mais variadas condições benignas e malignas do trato gastrointestinal (desde o esófago ao reto). Além da expansão nas indicações, o aprimoramento tecnológico contínuo e o desenvolvimento de novas próteses endoscópicos resultaram num maior sucesso dessas abordagens e, em alguns casos, permitiram novas aplicações. Esta revisão tem como objetivo resumir as melhores práticas em colocação de próteses endoscópicas esofágicas, gastroduodenais e colorretais.

Endoscopic treatment of upper gastrointestinal postsurgical leaks: a narrative review.

Upper gastrointestinal postsurgical leaks are life-threatening conditions with high mortality rates and are one of the most feared complications of surgery. Leaks are challenging to manage and often require radiological, endoscopic, or surgical intervention. Steady advancements in interventional endoscopy in recent decades have allowed the development of new endoscopic devices and techniques that provide a more effective and minimally invasive therapeutic option compared to surgery. Since there is no consensus regarding the most appropriate therapeutic approach for managing postsurgical leaks, this review aimed to summarize the best available current data. Our discussion specifically focuses on leak diagnosis, treatment aims, comparative endoscopic technique outcomes, and combined multimodality approach efficacy.

Technical Review on Endoscopic Treatment Devices for Management of Upper Gastrointestinal Postsurgical Leaks.

Upper gastrointestinal postsurgical leaks are challenging to manage and often require radiological, endoscopic, or surgical intervention. Nowadays, endoscopy is considered the first-line approach for their management, however, there is no definite consensus on the most appropriate therapeutic approach. There is a wide diversity of endoscopic options, from close-cover-divert approaches to active or passive internal drainage approaches. Theoretically, all these options can be used alone or with a multimodality approach, as each of them has different mechanisms of action. The approach to postsurgical leaks should always be tailored to each patient, taking into account the several variables that may influence the final outcome. In this review, we discuss the important developments in endoscopic devices for the treatment of postsurgical leaks. Our discussion specifically focuses on principles and mechanism of action, advantages and disadvantages of each technique, indications, clinical success, and adverse events. An algorithm for endoscopic approach is proposed.

Best Practices in Pancreatico-biliary Stenting and EUS-guided Drainage.

Indications for endoscopic placement of endoluminal and transluminal stents have greatly expanded over time. Endoscopic stent placement is now a well-established approach for the treatment of benign and malignant biliary and pancreatic diseases (ie, obstructive jaundice, intra-abdominal fluid collections, chronic pancreatitis etc.). Ongoing refinement of technical approaches and development of novel stents is increasing the applicability and success of pancreatico-biliary stenting. In this review, we discuss the important developments in the field of pancreatico-biliary stenting, with a specific focus on endoscopic retrograde cholangiopancreatography and endoscopic ultrasound-associated developments.

Futuristic Developments and Applications in Endoluminal Stenting.

Endoscopic stenting is a well-established option for the treatment of malignant obstruction, temporary management of benign strictures, and sealing transmural defects, as well as drainage of pancreatic fluid collections and biliary obstruction. In recent years, in addition to expansion in indications for endoscopic stenting, considerable strides have been made in stent technology, and several types of devices with advanced designs and materials are continuously being developed. In this review, we discuss the important developments in stent designs and novel indications for endoluminal and transluminal stenting. Our discussion specifically focuses on (i) biodegradable as well as (ii) irradiating and drug-eluting stents for esophageal, gastroduodenal, biliary, and colonic indications, (iii) endoscopic stenting in inflammatory bowel disease, and (iv) lumen-apposing metal stent.

Analysis of Reported Adverse Events With Colonic Stents: An FDA MAUDE Database Study.

BACKGROUND: Colonic stents are indicated for preoperative and palliative decompression of large bowel obstruction. We aim to investigate post Food and Drug Administration (FDA) approval outcomes associated with colonic stents. MATERIALS AND METHODS: We analyzed postmarketing surveillance data from the FDA Manufacturer and User Facility Device Experience (MAUDE) database from January 2011 to December 2020. RESULTS: During the study period, 691 device issues and 742 patient complications were identified. The number of adverse events reported to the FDA mildly increased from 6.40% in 2011 to 7.4% in 2020. Most device complications were due to a positioning problem (n=201, 29%), followed by device break (n=60, 8.6%), delamination (n=41, 6.3%), and migration or expulsion device (n=38, 5.55%). A number of reports described an unclassified adverse event without specifying device or operator problem (n=141, 20.3%). The most reported patient adverse events were perforation (n=150, 20.1%), death (n=47, 6.3%), abdominal pain/discomfort (n=27, 3.6%), and peritonitis (n=24, 3.2%). CONCLUSION: Findings from the MAUDE database highlight rare but important patient and device complications which endoscopists and referring providers should be aware of before consideration for colonic stent placement.
