This is a retrospective study to evaluate the prevention of complications of metallic stent placement in patients with unresectable advanced esophageal cancer. A total of 87 patients were treated with 4 types of metal stents in the esophagus over a period of 18 years. Stent placement was technically successful. The most common prior treatment was chemoradiotherapy. There were no significant differences in the rate of patients with no complications among the prior treatments. Approximately, 30% of patients had the most common chest pain in complications...

A 50-year-old man with advanced pancreatic cancer was admitted for intractable severe vomiting 5-6 times a day, continuing over a week. He had been treated for advanced pancreatic cancer with chemotherapy for 6 months, and had undergone self-expandable metalic stent placement for obstructive jaundice due to the pancreatic cancer 4 months before admission. No abnormal findings suggesting gastrointestinal obstruction or brain metastasis were revealed on diagnostic imaging. We performed endoscopic ultrasound-guided celiac ganglia neurolysis twice by injecting ethanol into the celiac ganglion...

BACKGROUND AND STUDY AIMS: Laparoscopic sleeve gastrectomy (LSG) is gaining popularity in treating morbid obesity. Prior studies showed a 3.5% risk of gastric sleeve stenosis (GSS). There is no consensus on how to treat these patients, and the role of endoscopic therapy has been addressed in only a few studies. We aim to assess the efficacy and safety of endoscopic stenting in the management of GSS following LSG. PATIENTS AND METHODS: Retrospective data were reviewed from July 2009 to November 2013...

AIM: To evaluate the length and location of stenosis in the colon as predictors of technical and clinical outcomes of stent placement in patients presenting with obstructive colorectal cancer. METHODS: A prospective single-center cohort study of patients treated with a colonic stent for malignant obstruction, regardless of stenosis length or location. Stenosis length was assessed globally on the appropriate CT slice as well as by 3D CT reconstruction. We analyzed whether outcomes were different in patients with a right sided-tumor and/or a stenosis >4 cm long...

Vishal B Gohil, Jason B Klapman
Pancreas cancer is a fourth-leading cause of cancer death in the USA and its incidence is rising as the population is aging. The majority of patients present at an advanced stage due to the silent nature of the disease and treatment have focused more on palliation than curative intent. Gastroenterologists have become integral in the multidisciplinary care of these patients with a focus on providing endoscopic palliation of pancreas cancer. The three most common areas that gastroenterologists palliate endoscopically are biliary obstruction, cancer-related pain, and gastric outlet obstruction...

BACKGROUND: Endotherapy with plastic stent (PS) placement is the main modality for treating benign biliary strictures (BBSs). Fully covered self-expandable metal stents (FCSEMSs) are being increasingly used for BBS management, with high stricture resolution. However, traditional metal tents are associated with high migration, causing treatment failure. METHODS: We investigated the efficacy and safety of a new FCSEMS for postsurgical BBS treatment and compared these parameters between the FCSEMS and PS treatment through retrospective analysis...

PURPOSE OF REVIEW: Gastric outlet obstruction (GOO) can result from benign and malignant causes. Until recently, surgical gastrojejunostomy was the treatment of choice for patient with benign and malignant GOO with a good functional status. Endoscopic placement of luminal self-expandable metal stents is currently widely accepted as the first line of treatment for malignant GOO because of its effectiveness and minimally invasive nature. The main shortcoming of luminal stents is the high incidence of recurrent GOO most commonly because of tumor ingrowth/overgrowth...

BACKGROUND: Endoscopic bilateral self-expandable metallic stent (SEMS) placement for malignant hilar biliary obstructions (MHBOs) is technically demanding, and a second SEMS insertion is particularly challenging. A simultaneous side-by-side (SBS) placement technique using a thinner delivery system may mitigate these issues. AIMS: We aimed to examine the feasibility and efficacy of simultaneous SBS SEMS placement for treating MHBOs using a novel SEMS that has a 5...

INTRODUCTION: Emergency resection represents the traditional treatment for left-sided malignant obstruction. However, the placement of self-expanding metallic stents and delayed surgery has been proposed as an alternative approach. The aim of the current meta-analysis was to review the available evidence, with particular interest for the short-term outcomes, including a recent multicentre RCT. METHODS: We considered randomized controlled trials comparing stenting as a bridge to surgery and emergency surgery for the management of left-sided malignant large bowel obstruction, performing a systematic review in MEDLINE, PubMed database, and the Cochrane libraries...

BACKGROUND: Endoscopic sphincterotomy or endoscopic papillary balloon dilatation during endoscopic retrograde cholangiopancreatography (ERCP) are associated with a high risk of bleeding in patients receiving dual antiplatelet agents (APAs). However, the discontinuation of antiplatelet agents increases the risk of thromboembolic events in these patients. To date, the placement of self-expandable metal stents (SEMSs) in patients receiving dual APAs has not been well investigated. The aim of this study was to evaluate the feasibility and safety of SEMS placement for the removal of common bile duct (CBD) stones in patients in whom APAs were not discontinued...

BACKGROUND: Covered self-expandable metal stents (SEMS) are utilized for the management of benign and malignant esophageal conditions; however, covered SEMS are prone to migration. Endoscopic suture fixation may mitigate the migration risk of covered esophageal SEMS. Hence, we conducted a systematic review and meta-analysis to evaluate the effectiveness and safety of endoscopic suture fixation for covered esophageal SEMS. METHODS: Following PRISMA guidelines, we performed a systematic review from 2011 to 2016 to identify studies (case control/case series) reporting the technical success and migration rate of covered esophageal SEMS following endoscopic suture fixation...

OPINION STATEMENT: PURPOSE OF REVIEW: To review the recently published literature on biliary and pancreatic stents. RECENT FINDINGS: Covered self-expanding metal stents (SEMS) are increasingly being used in the endoscopic management of benign biliary strictures. Given the costs associated with SEMS, plastic stents are still the most commonly used stents. In this setting, SEMS are preferred over plastic stents for palliation of malignant biliary strictures due to superior patency and have a role in preoperative management of malignant biliary strictures...

To evaluate the safety and effectiveness of fixation of the fully covered self-expandable metal stent (SEMS) placement using a silk thread for complete closure of an anastomotic leak. An anastomotic leak is a life-threatening complication after gastrectomy. Although the traditional treatment of choice was surgical re-intervention, an endoscopic SEMS can be used alternatively.During the study period, we retrospectively reviewed consecutive patients who received a modified covered SEMS capable of being fixed using a silk thread (Shim technique) due to an anastomotic leak after gastrectomy to prevent stent migration...
