Factors associated with the long-term outcome of a self-expandable Colon Stent used for palliation of malignant colorectal obstruction
Surgical Endoscopy, 2010Co-Authors: Min Kyu Jung, Soo Young Park, Seong Woo Jeon, Young Oh Kweon, Yong Hwan Choi, Hun Kyu RyeomAbstract:Background The placement of self-expanding metal Stents (SEMS) is a safe and effective definitive procedure for the palliation of malignant colorectal obstruction. In this study, the clinical outcomes, including the technical and clinical success rates, and the risk factors associated with the long-term outcomes of palliative SEMS were evaluated. Methods From February 2002 to April 2008, 39 patients (18 men and 21 women) with malignant colorectal obstruction underwent placement of uncovered or covered Stents under fluoroscopic or endoscopic guidance. The mean age of the patients was 64.5 ± 14.6 years (range, 37–96 years). Results The technical success rate was 100% (39/39), and the clinical success rate was 87.2% (34/39). Five cases had failed relief of the obstruction due to the development of migration in two patients, two malfunctions, and one perforation. Four patients experienced late complications: migration managed with a palliative colostomy in two patients, tumor ingrowth managed successfully with a second Stent in one patient, perforation with an intraabdominal abscess at the upper margin of the Stent 4 months after Stenting in one patient. The location of the obstruction and the length of the Stent were significant factors associated with a good outcome. Shorter Stents (

Does use of a metallic Colon Stent as a bridge to surgery modify the pathology data in patients with Colonic obstruction? A case-matched study
Surgical Endoscopy, 2013Co-Authors: C Sabbagh, D Chatelain, Nathalie Trouillet, F Mauvais, Sif Bendjaballah, F Browet, Jeanmarc RegimbeauAbstract:Background In a recent propensity score study, we established that overall- and disease-free survival were worse after use of a Colonic Stent (CS) than after emergency surgery for Colonic obstruction. The present study sought to explain the association between CS use and poor survival by analyzing pathological specimens. Methods From January 1998 to December 2011, all patients with left obstructive Colon cancer and having been operated on with curative intent were included in the study. The primary end point involved a comparison of pathological data from the CS- and the surgery-only groups in a case-matched analysis (with the groups matched for the T stage). In a series of secondary analyses, we studied a range of factors known to be associated with adverse outcomes (microscopic perforation, vascular embolism, perineural invasion, and lymph node invasion) in the study population as a whole (in order to evaluate Stenting as an adverse factor) and in the CS group alone (in order to identify factors associated with a poor prognosis in this specific group of patients). Results A total of 84 patients were included in the study (50 in the CS group). Stenting was mentioned in only 70 % of the pathology lab reports ( n = 35/50). Twenty-five patients in the CS group were matched with 25 patients of the surgery-only group. Tumor ulceration ( p
