colonic stent

Jean-Frédéric LeBlanc, Myriam Martel, Alan N Barkun
Introduction. Data are conflicting when assessing indications for colorectal self-expandable metallic stents (SEMS) in managing acute malignant large bowel obstruction (MLO). In November 2014, European and American Societies published guidelines to aid in understanding which patients might benefit from colorectal stenting. Yet, there remain marked disparities in clinical practice. Methods. A web-based survey was sent to Gastroenterologists and Surgical Specialists across Quebec to assess physicians' knowledge and adherence to the indications for colonic SEMS placement in the management of MLO using eight clinical scenarios...

OBJECTIVE: Endovascular aneurysm repair (EVAR) is widely used with excellent results, but its infectious complications can be devastating. In this paper, we report a multicenter experience with infected EVAR, symptoms, and options for explantation and their outcome. METHODS: We have reviewed all consecutive endograft explants for infection at 11 French university centers following EVAR, defined as index EVAR, from 1998 to 2015. Diagnosis of infected aortic endograft was made on the basis of clinical findings, cultures, imaging studies, and intraoperative findings...

INTRODUCTION: To examine the infectious outcomes after the insertion of the temporary prostatic urethral stent (TPUS) in benign prostatic hyperplasia (BPH) patients. MATERIAL AND METHODS: Between November 2007 and September 2012, ninety TPUS were used in 33 patients with BPH at our institution. All patients had negative urine cultures prior to the first stent insertion. TPUS were sent for cultures at time of removal or exchange. Stents were removed at the time of definite surgical intervention, at 4-6 weeks, or when patients elected another course of treatment...

BACKGROUND: The short-term safety and efficacy of a self-expandable metallic colonic stent (SEMS) insertion followed by elective surgery, "bridge to surgery (BTS)", for malignant large-bowel obstruction (MLBO) have been well described comparing with emergency surgery. The aim of this study was to compare short-term outcomes of endoscopic decompression using a SEMS versus a transanal decompression tube (TDT). MATERIALS AND METHODS: From January 2005 to November 2014, a total of 101 patients with MLBO underwent surgery at our single institution were retrospectively identified...

The feasibility of endoscopic resection for synchronous early colon cancer after placement of self-expandable metallic stents (SEMS) for malignant colorectal obstruction is unknown. Herein we evaluated 3 cases of endoscopic resection for synchronous early colorectal cancers after SEMS placement. Patient 1 was an 82-year-old man with obstructive sigmoid colon cancer. We curatively treated the synchronous descending colon cancer with endoscopic submucosal dissection (ESD) and the rectal cancer with endoscopic mucosal resection (EMR) after SEMS placement...

OBJECTIVES: Sepsis is associated with cardiac contractile dysfunction attributed to alterations in Ca handling. We examined the subcellular mechanisms involved in sarcoplasmic reticulum Ca loss that mediate altered Ca handling and contractile dysfunction associated with sepsis. DESIGN: Randomized controlled trial. SETTING: Research laboratory SUBJECTS:: Male wild type and transgenic mice INTERVENTIONS:: We induced sepsis in mice using the colon ascendens stent peritonitis model...

INTRODUCTION: Colonic stenting has evolved to be an alternative to emergency laparotomy in the management of acute left-sided malignant colonic obstruction. This retrospective comparative study aimed to review the outcomes of colonic stent as bridge to surgery with emergency operation in a regional hospital in Hong Kong. METHOD: Consecutive patients who were admitted from January 2006 to July 2014 with diagnosis of malignant left-sided colonic obstruction (from splenic flexure to rectosigmoid colon) were included...

BACKGROUND: Emergency surgery for colon cancer, as a result of obstruction, has been vitiated by a high frequency of complications and poor survival. The concept of "bridge to surgery" includes either placement of self-expanding metallic stents (SEMS) or diverting stoma of an obstructing tumour and subsequent planned resection. The aim of this study was to compare acute resection with stoma or stent and later resection regarding surgical and oncological outcomes and total hospital stay...

BACKGROUND: FTY720 is an immunosuppressive molecule licensed for the treatment of chronic relapsing multiple sclerosis (MS). It attenuates the adaptive immune response by sequestering T cells within secondary lymphoid organs via its action as functional antagonist of sphingosine-1-phasphate. To date it is unknown whether FTY-induced lymphopenia puts MS patients at increased risk for severe forms of postoperative infectious complications such as abdominal sepsis. OBJECTIVES: To determine the effect of FTY720-induced lymphopenia on survival to sepsis secondary to postoperative intraabdominal infections in a murine model of polymicrobial sepsis...

LT for PFIC type 1 is often complicated by postoperative diarrhea and recurrent graft steatosis. A 26-month-old female child with cholestatic jaundice, pruritus, diarrhea, and growth retardation revealed total bilirubin 9.1 mg/dL, gamma-glutamyl transpeptidase 64 IU/L, and TBA 295.8 μmol/L. Genetic analysis confirmed ATP8B1 defects. A LT (segment 2, 3 graft) from the heterozygous father was performed. Biliary diversion was performed by a 35-cm jejunum conduit between the graft hepatic duct and the mid-transverse colon...

INTRODUCTION: Large high-output enterocutaneous fistulas pose great difficulties, especially in the setting of recent surgery and compromised skin integrity. METHODS: This video demonstrates a new technique of endoscopic control of enterocutaneous fistula by using two covered overlapping stents. In brief, the two stents are each inserted endoscopically, one proximal, and the other distal to the fistula with 2 cm of each stent protruding cutaneously. Following this, the proximal stent is crimped and intussuscepted into the distal stent with an adequate overlap...

Stenting of malignant colonic obstructions using self-expanding metal stents (SEMS) is commonly used for palliation and can be used as an interim procedure prior to definitive surgery. We retrospectively reviewed prospectively collected data from all consecutive colonic stenting procedures undertaken between September 2007 and December 2014 at a district general hospital. Technical and clinical success rates, mortality, colonic perforation, and other complications were documented and analyzed. Sixty-four colonic stenting procedures were undertaken...

INTRODUCTION: Pneumatosis intestinalis is one of serious conditions following mechanical bowel obstruction. Emergency surgery is generally required to be a definite treatment in these patients of pneumatosis intestinalis, because of its risk of bowel ischemia and perforation. Since the operation in unprepared colon usually resulted in unfavorable outcome, the use of colonic stent is considered one of potential options as a bridge to definitive surgery. Presently, there is no widely published report of using colonic stent in these patients, particularly for stepping to curative surgery...

Self-expandable stents for obstructing colorectal cancer (CRC) offer an alternative to operative management. The objective of the study was to determine stent utilization for CRC obstruction in the province of Ontario between April 1, 2000, and March 30, 2009. Colonic stent utilization characteristics, poststent insertion health outcomes, and health care encounters were recorded. 225 patients were identified over the study period. Median age was 69 years, 2/3 were male, and 2/3 had metastatic disease. Stent use for CRC increased over the study period and gastroenterologists inserted most stents...
