Self-expanding metal stents can be considered as initial treatment for malignant large bowel obstruction in the palliative setting. It is suggested that systemic anti-angiogenic therapy increases the risk of stent perforation. We report a 65-year-old woman with a metastatic, obstructing colon tumor who has been successfully treated with stent placement and chemoimmunotherapy consisting of capecitabine and bevacizumab for 8 years.

Malignant ureteral obstruction is usually caused by an extrinsic compression including intra-abdominal cancers. One of the treatment modalities decompressing the obstruction is applying stent to open the ureter. Metallic Stent is an effective instrument which we used for the first time in Iran in our patient who had a metastatic colon cancerwith a single kidney and we used a Novel, Double-Layered, Coated, Self-expandable Metallic Mesh Stent (Uventa Stent) to keep the ureter open. After six months of follow up with ureteroscopy, there was no obstruction any more...

BACKGROUND AND AIM: EUS-guided hepaticogastrostomy (EUS-HGS) is performed as an alternative to the percutaneous or surgical approach. Despite high success rates, the adverse events rate is high. Recently, we used 6-mm fully-covered self-expandable metal stents (FCSEMS) to prevent adverse events and allow easy re-intervention. The purposes were to evaluate the safety, feasibility and clinical efficacy. METHODS: A prospective study to confirm the safety of EUS-HGS was carried out in six patients, followed by a trial to evaluate the feasibility and efficacy of EUS-HGS in approximately 12 additional patients...

Background and study aims : Self-expandable metallic stents (SEMS) have been increasingly used in benign conditions (e. g. strictures, fistulas, leaks, and perforations). Fully covered SEMS (FSEMS) were introduced to avoid undesirable consequences of partially covered SEMS (PSEMS), but come with higher risk of stent migration. Endoscopic suturing (ES) for stent fixation has been shown to reduce migration of FSEMS. Our aim was to compare the outcomes of FSEMS with ES (FS/ES) versus PSEMS in patients with benign upper gastrointestinal conditions...

Covered self-expandable metallic stents (CSEMS) may provide palliative drainage for unresectable distal malignant biliary strictures. Laser-cut CSEMS allows easy positioning due to its characteristic of minimal stent shortening. Endoscopic stent removal is sometimes recommended for recurrent biliary obstruction (RBO). However, there are no previous reports of endoscopic removal of laser-cut CSEMS. The current study presents data from 6 patients who were placed a laser-cut CSEMS for unresectable distal malignant biliary strictures, and later endoscopic stent removal was attempted for RBO at the present institute...

The patient was a 70-year-old woman who was diagnosed with obstructive transverse colon cancer suspected of invading the abdominal wall by abdominal CT imaging. Since the preoperative electrocardiogram showed an ischemic change, echocardiography and coronary angiography were performed. We diagnosed chronic heart failure and angina pectoris because echocardiography showed low cardiac function(left ventricular ejection fraction; LVEF 37%)and coronary angiography indicated triple-vessel disease. We firstly performed coronary artery bypass graft surgery following self-expanding metallic stent placement as a bridge to surgery(BTS), because we judged this patient as a perioperative high-risk case...

There have been many reports on ERCP for patients with alteredgastrointestinal anatomy(AGA), using balloon-assisted enteroscopy(BAE); however, BAE is not commonly usedin practice because it requires special endoscopic systems and accessories, which are time-consuming to operate. For this reason, patients with AGA who suffer from obstructive jaundice (OJ)might receive PTBD in general practice during emergency situations. We report a case of OJ, caused by recurrent gastric cancer andpreviously treatedwith distal gastrectomy andRoux -en-Y reconstruction(DGRY)...

Case is a 66-year-old male. He was inserted covered self expandable metallic stent(SEMS)for jejunal stenosis due to gastric cancer recurrence. Migration was occurred after 4 days from stent replacement. We had removed SEMS by endoscopy, and re-inserted non-covered SEMS. Two months later, stent stenosis was occurred by tumor ingrowth. We tried to insert another stent in the stenotic stent. The patient was able to maintain oral intake without complication for 3 months. SEMS placement would improve a quality of life for selected patients with recurrent jejunal stenosis...

A 88-year-old female suffered of ileus due to advanced transverse colon cancer. Pneumonia was observed and nutrient condition was bad. Operation was found to be difficult because of the bad condition with complication on this present time. Self-expandable metallic stent(SEMS)was inserted to extend obstruction. But SEMS dropped out next day and SEMS, thicker than previous one, was reinserted. Main tumor was huge protruding tumor and the reason of ileus was invagination of the cancer. The fixation of SEMS was not so good, but the generalcondition was improved while a week after reinsertion of SEMS...

The placement of a self-expanding metallic stent (SEMS) in obstructive colorectal cancer (OCRC) is acknowledged to be a safe and effective procedure for the relief of obstruction. However, there is concern that shear forces acting on the tumor during stent expansion may release cancer cells into the circulation, resulting in a poor prognosis. The aim of the present study was to determine whether colonic stent insertion increases viable circulating tumor cells (v-CTCs). A telomerase-specific replication-selective adenovirus-expressing GFP (TelomeScanF35) detection system was used to detect v-CTCs in 8 OCRC patients with a SEMS before and after stent insertion and after surgical resection...

BACKGROUND/AIMS: Self-expandable metallic stent (SEMS) placement with fluoroscopic guidance is a commonly used technique to relieve obstruction in patients with esophageal carcinoma. However, it has disadvantages such as radiation exposure. SEMS placement with endoscopic guidance also has the disadvantages of causing discomfort to patients as the endoscope and SEMS assembly are simultaneously used and it needs two experts for the procedure to be performed. To overcome these disadvantages, a simplified technique for SEMS placement was developed that does not require fluoroscopic or endoscopic guidance...
