Self-expandable metallic stents (SEMSs) are used for the management of malignant colorectal obstruction. A patient who underwent colonic uncovered SEMS insertion for extraluminal stenosis in the splenic flexure of the transverse colon due to advanced gastric cancer is herein reported. The patient presented with a fracture of the colonic SEMS 494 days after SEMS insertion. Although various complications of stenting have previously been reported, the details of fractures of colonic SEMSs have not yet been reported...

The most common biliary complication after liver transplantation is anastomotic stricture (AS) and it can occur isolated or in combination with other complications. Liver graft from a cadaveric donor or a living donor has an influence on the incidence of biliary strictures as well as on the response to endoscopic treatment. Endoscopic treatment using balloon dilation and insertion of biliary stents by endoscopic retrograde cholangiopancreatography (ERCP) is the initial approach to these complications. AIM: The aim of this article is to compare different endoscopic techniques to treat post-liver transplantation biliary strictures...

BACKGROUND: Self-expandable metal stents (SEMSs) are widely used for malignant biliary obstructions. Nitinol-covered SEMSs have been developed to improve stent patency. Currently, SEMSs may be uncovered, partially covered, or fully covered; however, there is no consensus on the best stent type for the management of malignant distal biliary obstruction (MDBO). METHODS: Patients with unresectable MDBO receiving SEMS (Wallflex™) were retrospectively analyzed. Time to recurrent biliary obstruction (TRBO) and survival time were compared among the three types of SEMSs...

Self-expanding metal stenting is an established treatment modality in the management of esophageal growth and stricture. Reactive tissue ingrowth at the uncovered portion of the self-expanding metal stent (SEMS) anchors it in position, preventing its migration. When removal of such an embedded SEMS is clinically indicated, the procedure of endoscopic retrieval is fraught with serious complications. Temporary deployment of a larger fully covered "rescue" SEMS within the embedded SEMS has been reported to be useful in the extraction of the embedded SEMS...

In the report, we describe a case of refractory benign esophageal strictures from esophageal cancer after an operation for the placement of three partially covered self-expanding metal stents (SEMSs), which were all embedded in the esophageal wall. Using the stent-in-stent technique, the three embedded SEMSs were successfully removed without significant complications. To the best of our knowledge, few cases of the successful removal of multiple embedded esophageal SEMSs have been reported in the literature...

AIM: To investigate the factors predictive of failure when placing a second biliary self-expandable metallic stents (SEMSs). METHODS: This study evaluated 65 patients with an unresectable malignant hilar biliary obstruction who were examined in our hospital. Sixty-two of these patients were recruited to the study and divided into two groups: the success group, which consisted of patients in whom a stent-in-stent SEMS had been placed successfully, and the failure group, which consisted of patients in whom the stent-in-stent SEMS had not been placed successfully...

BACKGROUND: Acute necrotizing pancreatitis (ANP) is complicated with segmental portal hypertension (PHT) and formation of venous collaterals. Presence of collaterals in vicinity of endoscopic transmural tract can lead to potentially catastrophic situation. Here, we report safety and outcome of EUS-guided transmural drainage of walled-off pancreatic necrosis (WOPN) in patients with PHT and intra-abdominal collaterals. METHODS: Retrospective analysis of collected database of patients (n=18; age 40...

The prognosis of pancreatic cancer remains poor, even after initial surgical therapy. Local recurrence after Whipple's pancreatico-duodenectomy may lead to intestinal obstruction at the level of the afferent limb or the alimentary limb. Endoscopic insertion of a self-expandable metal stent (SEMS) into the intestinal malignant stricture is the preferred method of choice for palliation. We describe two new endoscopic techniques to treat a malignant intestinal obstruction with the insertion of a SEMS into the afferent limb and the alimentary limb...

PURPOSE OF REVIEW: Acute gastrointestinal bleeding is a frequent emergency situation, whose incidence will likely rise as a result of the increasing use of direct anticoagulants and of the medical progresses resulting in longer life expectancy with underlying comorbidities. Updated guidelines and improvements in the diagnostic and therapeutic tools are now available and will likely improve the management of massive gastrointestinal bleeding in the near future. RECENT FINDINGS: The assessment of severity has been improved by validated scores useable upon admission...

Intestinal obstruction is a common complication in patients with advanced gastrointestinal malignancies. In the last two decades, endoscopic placement of duodenal stents has become a mainstay of palliative treatment in patients with unresectable obstructive duodenal pathology. Self-expandable metal stents have been reported to have excellent success rates, besides dramatically improve the patient's quality of life by reinstating the oral feeding ability. Re-intervention rates remain high, commonly as a consequence of tumour ingrowth resulting stent occlusion...

Background and study aims  Self-expandable metallic stents (SEMS) have been widely used for left-sided colorectal obstruction. Few studies on SEMS placement for right-sided colonic obstructions have been reported because stenting in the right colon is technically difficult, particularly in the ileocecal region. We present 4 cases of successful bridge-to-surgery stenting for ileocecal cancer. Using an endoscopic retrograde cholangiopancreatography catheter with a movable tip and a decompression tube was effective for stenting...
