BACKGROUND: The aim of colonic stenting with self-expandable metallic stents in neoplastic colon obstruction is to avoid emergency surgery and thus potentially reduce morbidity, mortality, and need for a stoma. Concern has been raised, however, about the effect of colonic stenting on short-term complications and long-term survival. We compared morbidity rates after colonic stenting as a bridge to surgery (SBTS) versus emergency surgery (ES) in the management of left-sided malignant large-bowel obstruction...

BACKGROUND: Bilateral stent-in-stent (SIS) self-expandable metal stent placement is technically challenging for palliation of unresectable malignant hilar obstruction. In the SIS technique, the uniform large cell type biliary stent facilitates contralateral stent deployment through the mesh of the first metallic stent. This study aimed to assess the technical success and clinical effectiveness of this technique with a uniform large cell type biliary stent. METHODS: Thirty-one patients who underwent bilateral SIS placement using a large cell type stent were reviewed retrospectively...

A 67-year-old male was diagnosed with advanced esophageal cancer. A computed tomography scan showed multiple intra-abdominal lymphadenopathies. Because the tumor was thought to be unresectable, we initiated chemotherapy. Twelve months later, the patient was admitted to our hospital because of hematemesis. Gastroduodenoscopy revealed oozing bleeding from the esophageal tumor. Hemostasis was not achieved with conservative treatment, and frequent blood transfusions were required. Endoscopic hemostasis was difficult to achieve because of the malignant esophageal stenosis...

The use of self-expanding metallic stents (SEMS) is the current treatment of choice for malignant gastrointestinal obstructions. A paclitaxel-eluting metallic SEMS (PEMS) may have an antitumor effect on esophageal tissue. PEMS with 10% paclitaxel or conventional SEMS were inserted into the lower esophagus of rabbits. Following the insertion of the stents for 1, 2, 4 and 6 weeks, the rabbits were sacrificed and the status of the stent insertion was examined, as well as any macroscopic or microscopic mucosal changes in the esophageal tissue...

Bleeding from esophageal varices is a major cause of mortality in patients with advanced liver disease. Although standard treatment and secondary prophylaxis are effective, in some patients sustained hemostasis cannot be achieved. We report the case of a woman with alcoholic liver disease in whom pharmacological, endoscopic, and intravascular therapies failed to control variceal bleeding. Only a combination of (repeated) band ligation, insertion of a self-expanding metal stent, TIPS implantation and redilatation, transjugular variceal embolization, and finally implantation of a portocaval shunt proved to be successful...

BACKGROUND: Self-expanding metal stents can be used as bridge to elective surgery for acute malignant colonic obstruction. However, the impact on long-term oncological outcome and the optimal timing of surgery are still unknown. METHOD: This was a retrospective multicenter study performed at four colorectal centers. Patients undergoing stent placement as bridge to surgery, between January 2010 and December 2013, were included in the study. Primary outcomes were survival and recurrence rates along with location of the metastases...

INTRODUCTION: Esophageal cancer (EC) and human immunodeficiency virus (HIV) are common in parts of South Africa. Squamous cell carcinoma of the esophagus in KwaZulu-Natal, South Africa presents generally in advanced stages and is mostly palliated by the deployment of self-expandable metal stent (SEMS). This study analyses these relationships between coexistent HIV infection, SEMS deployment, and survival scores. METHODOLOGY: Information on patients managed with SEMS between October 2013 and December 2014 was retrieved from a prospective database of EC and followed up until April 2015...

OBJECTIVES: Self-expandable metal stents (SEMS) are thought to have an advantage over plastic stents in achieving biliary drainage. METHODS: We performed a systematic search of MEDLINE, EMBASE, Scopus, CENTRAL, and ISI Web of knowledge databases, from January 1980 to September 2015, for randomized-controlled trials (RCTs) comparing SEMS vs. plastic stents in the palliation of malignant biliary obstruction. Primary outcomes were durations of stent patency, patient survival, and 30-day mortality...

INTRODUCTION: The close anatomical relationship between the oesophagus and bronchial tree results in formation of an oesophago-respiratory fistula in a subset of patients with advanced oesophageal or lung cancer. In those patients stenting of both the oesophagus and tracheobronchial tree is a valid option of palliative treatment. AIM: To determine the effectiveness, tolerance, quality of life, safety and survival after double stenting procedures. MATERIAL AND METHODS: Retrospective analysis of a prospectively collected database was performed, concerning consecutive patients with oesophago-respiratory fistulas treated with double stenting...

Occurrence of bronchial artery aneurysm is rare, and it has been detected in less than 1 % of all selective bronchial arteriography cases. Here, we present a case of a bronchial artery aneurysm caused by a tracheal stent migration. A 59-year-old man was operated on for esophageal cancer, where an esophageal-tracheal fistula occurred 1 week after operation. Surgical repair of the esophageal-tracheal fistula was performed using a muscle flap, but this not results in fistula closure. Consequently, a self-expanding covered metallic tracheal stent was implanted for rescue, and this resulted in fistula closure...
