Laparoscopy and endoscopy cooperative surgery (LECS) for colorectal tumors is not only a minimally invasive treatment, but also a safer therapy. It mainly includes laparoscopy-assisted colonoscopic resection and colonoscopy-assisted laparoscopic surgery. Laparoscopy-assisted colonoscopic procedure can make endoscopic resection more "aggressive". Performers can directly observe to ensure normal intestinal wall, and the intestinal defect can be directly repaired. If suspected malignant tumor can not be removed by colonoscopy, the laparoscopic surgery can be performed...

BACKGROUND: Self-expandable metal stent (SEMS) insertion and percutaneous gastrostomy (PG) feeding are commonly used for patients with esophageal cancer and dysphagia. This study aimed to compare outcomes between SEMS insertion and PG feeding for them. METHODS: We retrospectively analyzed 308 patients with esophageal cancer who underwent fully covered SEMS insertion (stent group) or PG (gastrostomy group) for dysphagia due to tumor. Patients with other causes of dysphagia, such as radiation-induced or postoperative stricture, were excluded from the study...

BACKGROUND: Anastomotic bile duct stricture (ABS) remains as one of the most common complications in liver transplant patients. Current practice of endoscopic retrograde cholangiopancreatography (ERCP) with insertion of plastic stent (PS) often requires multiple procedures before achieving stricture resolution. To date, studies utilizing covered self-expandable metallic stent (cSEMS) in ABS management reported varying degree of efficacy. The aim of this study was to analyze long term efficacy of cSEMS in patients with ABS, and identifying factor(s) influencing the probability of stricture resolution...

BACKGROUND AND OBJECTIVES: Endoscopic ultrasound (EUS)-guided biliary drainage techniques are alternative procedures in cases of obstructive jaundice with altered anatomy or failed ERCP. Complications related to EUS-guided antegrade drainage (EUS-AD) are still present in up to 10% of cases, and combination of procedures is sometimes suggested to avoid adverse events. The purpose of our study is to evaluate the efficacy and safety of EUS-AD with transhepatic access in case of technical success...

Distal malignant biliary obstruction (MBO) leads to obstructive jaundice as a result of when the bile excretion from the liver is disturbed and induces hepatic failure and sepsis, which when complicated with cholangitis, it becomes necessary to perform drainage for the MBO. For biliary drainage, we can perform a surgical bypass operation, percutaneous transhepatic biliary drainage (PTBD), endoscopic biliary drainage (EBD) via duodenal papilla, or endoscopic ultrasound (EUS)-guided biliary drainage (EUS-BD), which is a transgastrointestinal biliary drainage...

Gastric outlet obstruction (GOO) is one of severe comorbidities caused by many kinds of malignant diseases and is associated with not only degradation of patients' quality of life but also mortality. Although surgical bypass is one of the main therapies for malignant GOO, it is often difficult to perform in end-stage patients. The deployment of self-expandable metallic stents (SEMSs) has recently become a viable alternative to surgical bypass for malignant GOO. This technique is less invasive and more effective, particularly in patients with poor prognoses...

Living donor liver transplantation (LDLT) is an effective alternative to deceased liver transplantation (DDLT) for end-stage liver disease. Although advances in surgical techniques, immunosuppressive management, and post-transplant care have improved the overall outcomes of LDLT, biliary strictures remain the major unsolved problem. Endoscopic retrograde cholangiopancreatography (ERCP) is currently considered the first-line therapy for biliary strictures following LDLT with duct-to-duct reconstruction, with percutaneous and surgical interventions reserved for patients with unsuccessful management via ERCP...

INTRODUCTION: Benign esophageal strictures are relatively frequent and can severely affect the quality of life of a patient. Stenting has been proposed for the treatment of refractory cases. Lesions affecting the cervical esophagus are more difficult to treat, and the placement of stents in this location has traditionally been restricted due to potential adverse events. The aim of this study was to describe the efficacy and safety of endoscopic stenting in the management of refractory benign cervical esophageal strictures (RBCES) in a single-center cohort study...

Small intestinal obstruction is a common complication of primary gastrointestinal cancer or metastatic cancers. Patients with this condition are often poor candidates for surgical bypasses, and placement of self-expanding metal stent (SEMS) can be technically challenging. In this study, we examined the feasibility of combined application of single-balloon enteroscope (SBE) and colonoscope for SEMS placement in patients with malignant small intestinal obstruction. Thirty-four patients were enrolled in this study, among which 22 patients received SEMS placement by using SBE and colonoscope, while the other 12 patients received conservative medical treatment...

The AXIOS stent (Boston Scientific, Marlborough, MA) is a novel lumen-apposing self-expandable metallic stent designed for enteric drainage of nonadherent lumens. Efficacy and safety of using the AXIOS stent for pancreatic fluid drainage have been consistently shown in several studies. Although it is less common with this novel stent, stent migration still may happen. We present a case of AXIOS stent migration into the esophagus.

Esophageal stents have been used to palliate patients with dysphagia caused by esophageal cancer. Early rigid plastic prostheses have been associated with a high risk of complications. However, with the development of self-expanding stents, it has developed into a widely accepted method for treating malignant esophageal strictures and esophagorespiratory fistulas (ERFs). The present review covers various aspects of self-expanding metallic stent placement for palliating esophageal cancer, including its types, placement procedures, indications, contraindications, complications, and some of innovations that will become available in the future...

INTRODUCTION: Stents have been used for quite some time for the treatment of benign and malignant airway stenosis. Silicon stents are preferred for benign situations, whereas metallic self-expanding stents are preferred for malignant comorbidities. PATIENT AND METHODS: In general, stents can be placed in different approach directions, although in pulmonary medicine it is logical to apply only antegrade techniques - until now. A 63-year-old patient, 168 cm height and 53 kg weight on referral, suffered chronical diseases...

BACKGROUND AND AIMS: Self-expandable metallic stents are increasingly used in the treatment of obstructing colorectal cancer (CRC). Although endoscopic colonic stenting is widely accepted in palliation, disagreement exists about its role in a curative setting. This study aims to describe long-term survival data in a large patient group, treated with colonic stenting as a bridge to surgery (BTS) for CRC. PATIENTS AND METHODS: This prospective study included 97 patients who presented in a Belgian hospital between 1998 and 2013 with an obstructing, though potentially curable, CRC...

Self-expandable metal stents (SEMSs) are used for the management of certain esophageal conditions such as strictures, perforations, and fistulae. These can be placed using fluoroscopic control, endoscopic control, or a combination of both. We evaluated our institutional experience of placing a SEMS using only endoscopy without the aid of fluoroscopy to determine safety and feasibility using this technique. A retrospective review was performed to identify all patients who underwent esophageal SEMS from January 2010 to June 2015...
