- Background
/Aims: Self-expanding metallic stents (SEMS) are an alternative to emergency surgery (ES) for malignant colorectal obstruction. This study aimed to compare surgical outcomes between SEMS as a bridge to surgery (BTS) and ES in patients with malignant colorectal obstruction.
Methods
A comprehensive database search was conducted until October 2023 to compare outcomes between SEMS as a BTS and ES. A subgroup analysis of results by malignancy site was performed.
Results
We analyzed 57 studies, including 7,223 patients over a mean duration of 35.4 months. SEMS as a BTS showed clinical and technical success rates of 88.0% (95% confidence interval [CI], 86.1%–90.1%; I2=68%) and 91.6% (95% CI, 89.7%–93.7%; I2=66%), respectively. SEMS as a BTS revealed reduced postoperative adverse events (odds ratio [OR], 0.51; 95% CI, 0.41–0.63; I2=70%; p<0.001) and 30-day mortality (OR, 0.52; 95% CI, 0.37–0.72; I2=10%; p<0.001) compared to ES. Subgroup analysis showed postoperative mortality of 5% and 1.5% for left- and right-sided malignancies, respectively. Adverse events were 15% and 33% for the right and left colon, respectively.
Conclusions
SEMS as a BTS demonstrated a higher success rate, fewer postoperative adverse events, and a reduced 30-day mortality rate than ES, supporting its use as the preferred initial intervention for right- and left-sided obstructions and indicating broader clinical adoption.

Palliation of jaundice improves the general health of the patient and, therefore, surgical outcomes. Because of the complexity and location of strictures, especially proximally, drainage has been accompanied by increased morbidity due to sepsis. Another concern is the provocation of an inflammatory and fibrotic reaction around the area of stent placement. Preoperative biliary drainage with self-expanding metallic stent (SEMS) insertion can be achieved via a percutaneous method or through endoscopic retrograde cholangiopancreatography. A recently published multicenter randomized Dutch study has shown increased morbidity with preoperative biliary drainage. A Cochrane meta-analysis has also shown a significantly increased complication rate with preoperative drainage. However, few of these studies have used a SEMS, which allows better biliary drainage. No randomized controlled trials have compared preoperative deployment of SEMS versus conventional plastic stents. The outcomes of biliary drainage also depend on the location of the obstruction, namely the difficulty with proximal compared to distal strictures. Pathophysiologically, palliation of jaundice will benefit all patients awaiting surgery. However, preoperative drainage often results in increased morbidity because of procedure-related sepsis. The use of SEMS may change the outcome of preoperative biliary drainage dramatically.

Use of colorectal stents has increased dramatically over the last decades. Colorectal stents offer an alternative way to relieve fatal intestinal obstruction and can take place of emergency surgery, which associated with significant morbidity and mortality and a high incidence of stoma creation, to elective resection. Although there remain a few concerns regarding the use of stents as a bridge to surgical resection, use of self-expandable metallic stents for palliation in patients with unresectable disease has come to be generally accepted. Advantages of colorectal stents include acute restoration of luminal patency and allowance of time for proper staging and surgical optimization, and the well-known disadvantages are procedure-related complications including perforation, migration, and stent failure. General indications, procedures, and clinical outcomes as well as recent evidences regarding the use of colorectal stents will be discussed in this review.
