Abstract
BACKGROUND With acute obstruction due to rectal or recto-sigmoid cancer, the safety and success of deploying self-expandable metal stents has been controversial. The aim of this systematic review was to synthesize the existing evidence on the outcomes and complication rates of stent placement in these patients. METHODS We performed a literature search of PubMed by using appropriate keywords, and manual reference screening of included articles was done. The article screening, data extraction, and quality assessment was done by four independent reviewers. A meta analyses was performed for the main outcome measures: technical and clinical success and complication rates. RESULTS We identified 962 articles in the search. After applying inclusion and exclusion criteria, we included 32 articles in the meta-analysis. The pooled technical success rate across 26 studies that reported it was 97% [95% confidence interval (CI): 95%-99%] without evidence of significant heterogeneity (I2 = 0.0%, P = 0.84), and the clinical success rate across 26 studies that reported it was 69% (95% CI: 58%-79%) with evidence of significant heterogeneity (I2 = 81.7%, P < 0.001). The pooled overall complication rate across the 32 studies was 28% (95% CI: 20%-37%) with evidence of significant heterogeneity (I2 = 79.3%, P < 0.001). CONCLUSION The use of rectal stents in obstructing rectal or recto-sigmoid tumors seems to be technically feasible. A high rate of technical success, however, does not always translate into clinical success. A considerable complication rate is associated with this approach. Randomized controlled trials are needed to compare the outcomes of rectal stent placement with those of surgery.

Palliative Stent Insertion for Acute Malignant Colorectal Obstruction: Long-term Patency and Survival. Surg Laparosc Endosc Percutan Tech 2016; 25:500-4.

Abstract
PURPOSE To investigate the long-term outcome of palliative stent insertion for acute malignant colorectal obstruction. METHODS From May 2009 to February 2015, consecutive patients with acute malignant colorectal obstruction underwent palliative stent insertion in our center. Technical success, clinical success, and long-term outcomes were analyzed retrospectively. RESULTS A total of 45 patients with acute malignant colorectal obstruction underwent palliative stent insertion. Technical success was achieved in 42 of 45 patients. Clinical success was achieved in 41 of 42 patients. During a follow-up of 5 days to 25 months (mean, 6.9±4.5 mo), the cumulative 6- and 12-month patency rates were 88.6% and 72.7%, respectively. The cumulative 6- and 12-month survival rates were 60.1% and 14.3%, respectively. The independent predictor of prolonging survival was subsequent chemotherapy after stenting (P=0.017). CONCLUSION Palliative colorectal stent insertion can provide a good long-term outcome in patients with malignant colorectal obstruction.

Placement of the Decompression Tube as a Bridge to Surgery for Acute Malignant Left-Sided Colonic Obstruction. J Gastrointest Surg 2015; 19:2243-8.

Abstract
PURPOSE The aim of this study is to investigate the feasibility, safety, and effectiveness of placing the decompression tube as a bridge to surgery for acute malignant left-sided colonic obstruction. METHODS From January 2009 to August 2014, consecutive patients with acute malignant left-side colonic obstruction underwent placement of the decompression tube as a bridge to surgery in our center. The technical and clinical success of placing the decompression tube was evaluated. Clinical success was defined as relief of obstructive symptoms within 48 h after placing the decompression tube. Elective tumor resection was performed 7-9 days after colonic decompression. The types of surgery, primary anastomosis rate, and follow-up findings were analyzed. RESULTS Twenty patients with acute malignant left-side colonic obstruction underwent placement of the decompression tube as a bridge to surgery. Placement of decompression tube was technically successful in all patients. No procedure-related complication occurred. Clinical success was achieved in 19 patients. Elective tumor resection and primary anastomosis were successfully performed in all 19 patients. The postoperative complications included wound infection (n = 2) and anastomotic stenosis (n = 1). CONCLUSION Decompression tube can serve as an easy, safe, and effective bridge to subsequent surgery for patients with acute malignant left-sided colonic obstruction.
