A Clinical Evaluation of Endoscopicallyplaced Self-Expanding Metallic Stents in Patients with Acute Large Bowel Obstruction

Abstract

Background and Aims: self-expanding metallic stents (sems) have since 1991 established themselves as an option in the treatment of large bowel obstruction. the aim of this study was to evaluate the use of sems in management of acute colorectal obstructions at a danish surgical gastroenterology center. Material and Methods: retrospective review of charts from all patients who, in the period marts 2002 to december 2007 underwent insertion of as ems for an acute large bowel obstruction.Results: of 45 patients included, sems was intended as a bridge to surgery in 20 patients and as palliation in 25 patients. for malignant etiology,the sems procedure was at echnical and clinical success in 97.4% of the cases. complications occurred in 21%, mortality rate 2,6%. for benign etiology,the sems procedure was atechnical success in 85.7%, and a clinical success in 71.4%. complications occurred in 71.4% of the benign cases with amortality rate of 28,6%.Conclusions: placement of sems for acute large bowel obstruction with malignant etiology is an effective and safe procedure with low mortality and morbidity. however results for benign obstructions are questionable and more research is needed to determine the role of sems.

Outcome of patients after endoluminal stent placement for benign colorectal obstruction

“…There is limited data on longterm follow-up and randomised studies do not exist. Many of the studies are case reports or the study populations are small [8][9][10][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. At the time of writing this report, the biggest series of patients treated with SEMS due to benign obstruction is 23 patients [11].…”

Systematic review of self‐expanding stents in the management of benign colorectal obstruction

“…The use of SES for the management of benign obstruction in the oesophagus and biliary system has been reported, with variable results [8,9]. Benign obstruction in the colon and rectum managed by SES has recently been investigated by a number of case series [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. This systematic review will report the efficacy and safety outcomes following endoscopic placement of SES for benign colorectal obstruction.…”

Colonic Stenting as a Bridge to Surgery in Malignant Large-Bowel Obstruction: A Report from Two Large Multinational Registries

“…Acute large-bowel obstruction represents a surgical emergency; in 85 % of cases, it is caused by the presence of a colorectal tumor ( 1 ). It has been reported that ~ 15 -20 % of patients with colorectal cancer present with an emergent obstruction of the large bowel at the time of diagnosis ( 2 ).…”
