background: recently, different investigators have studied the possibility of radiation therapy in restenosis prevention and have shown promising results. in this study a unique radioactive source for intra vascular brachytherapy (ivbt) was investigated. the two-dimensional dose distribution in water for a 32p ivbt stent has been calculated. the pure beta emitter source 32p has been coated on p...

Dear Editor: The ureteral stents are defined as devices that are inserted inside obstructive ureters to maintain patency. Ureteral obstruction caused by extrinsic compression is a challenge in the management of malignant diseases. First, adequate stent placement across an obstructed ureter does not necessarily guarantee urine patency. Moreover, the stent is poorly tolerated, severely impairing ...

OBJECTIVE Intestinal obstruction due to colorectal tumors requires immediate surgical decompression. Endoscopic stent placement for acute malignant colonic obstruction is gaining widespread acceptance as an alternative to emergency surgery. Our aim in this study was to evaluate the success and complication rates of endoscopic stenting for malignant colonic obstruction. MATERIAL AND METHODS Pa...

Background: There have been reports on stent-related vascular erosions about patients with benign or malignant stenosis of the esophagus who received endoscopic stent insertion for palliative intention for oral intake. Case presentation: A 61-year-old woman with esophageal cancer located in the middle part of esophagus was treated with esophagectomy. Two years following the surgery, malignan...

OBJECTIVE Few studies have reported the surgical treatment of carotid in-stent restenosis (ISR), more data and longer follow-up are needed. We describe the surgical treatment of ISR by standard carotid endarterectomy (CEA) with stent removal, including long-term follow-up in 10 patients from our centre. METHODS Ten patients from our centre who underwent CEA with stent removal for ISR were ret...

Background/Aim: Endoluminal self-expanding metallic stents (SEMS) may overcome the risk of mortality and morbidity acute intestinal obstruction because stage IV colon (CC) or rectal (RC) cancer. We evaluated QoL in these groups patients. Patients Methods: Forty-eight patients were enrolled a prospective longitudinal cohort single-center trial to undergo SEMS positioning. Twenty-five had CC 23 R...

1 of 3 DESCRIPTION An 86-year-old woman presented with complete large bowel obstruction secondary to tumour ingrowth of a previously placed enteric stent ( fi gure 1 ). She was deemed not fi t for surgical intervention. A second stent (covered ultrafl ex stent) was inserted through the occluded baremetal stent using a combination of endoscopy and fl uoroscopy ( fi gure 2 ). Recovery was unevent...

Abstract Aim Approximately a third of all colorectal cancers diagnosed in the UK each year are rectal origin and will undergo surgical resection with formation an anastomosis. Focus is placed on techniques to ensure anastomotic integrity however leak, pelvic sepsis, distance anal verge stapler choice established risk factors for benign stricture. This review aimed assess use endoscopic salvage ...

results twelve original studies fulfilled the inclusion criteria. the current literature suggests that the learning curve of robotic rectal surgery varies between 15 and 44 cases and is probably shorter to that of laparoscopic rectal surgery. conclusions there are only a few studies assessing the learning curve of robotic rectal surgery and they possess several differences in methodology and ou...

Surgery is the mainstay of treatment for gastrointestinal stromal tumors (GISTs). However, complete resection of rectal GISTs is sometimes difficult because of bulkiness and/or anatomical reasons. Neoadjuvant imatinib therapy has gained attention as an alternative treatment to increase the chance of en bloc resection of rectal GISTs, although it usually takes several months. In this case report...
