Emergence application of colonoscopic placement of self-expandable metal stent without fluoroscopic monitoring / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of colonoscopy-guided placement of self-expandable metallic stent without fluoroscopic monitoring in the emergence management for acute malignant colorectal obstruction.</p><p><b>METHODS</b>Clinical data of 42 patients (24 males and 18 females with a mean age of 64.3 years) undergoing colonoscopy-guided placement of self-expandable metallic stents without fluoroscopic monitoring for acute malignant colorectal obstruction between January 2010 and June 2012 were reviewed retrospectively.</p><p><b>RESULTS</b>The obstruction was located in the rectum (n=19), sigmoid (n=9), descending colon (n=8), splenic flexure (n=1), hepatic flexure (n=3), and ascending colon (n=2). Technical success was achieved in all the 42 patients (100%). The mean time of operation was (11.8±10.4) min (range 1.1-51.0 min). No serious procedure-related complication occurred. Minor bleeding occurred in 3 cases (7.1%). One patient died on the second day after surgery because of heart failure.</p><p><b>CONCLUSIONS</b>Colonoscopy-guided placement of self-expandable metallic stents without fluoroscopic monitoring in emergence management for acute malignant colorectal obstruction is effective and safe with shorter operative time.</p>
