Abstract Background To explore the long-term oncological safety of using self-expanding metal stents (SEMS) as a bridge to surgery for acute obstructive colorectal cancer by comparing the pathological results of emergency surgery (ES) with elective surgery after the placement of SEMS. Methods Studies comparing SEMS as a bridge to surgery with emergency surgery for acute obstructive colorectal cancer were retrieved through the databases of Pubmed, Embase, and Cochrane libraries, and a meta-analysis was conducted based on the pathological results of the two treatments. Risk ratios (OR) or mean differences (MD) with 95% confidence intervals (CI) were calculated for the outcomes under random effects model. Results A total of 27 studies were included, including 3 randomized controlled studies, 2 prospective studies, and 22 retrospective studies, with a total of 3737 patients. The presence of perineural invasion (RR = 0.58, 95% CI 0.48, 0.71, P < 0.00001), lymphovascular invasion (RR = 0.68, 95% CI 0.47, 0.99, P = 0.004) and vascular invasion (RR = 0.66, 95% CI 0.45, 0.99, P = 0.04) in SEMS group were significantly higher than those in ES group, and there was no significant difference in lymphatic invasion (RR = 0.92, 95% CI 0.77, 1.09, P = 0.33). The number of lymph nodes harvested in SEMS group was significantly higher than that in ES group (MD = − 3.18, 95% CI − 4.47, − 1.90, P < 0.00001). While no significant difference was found in the number of positive lymph nodes (MD = − 0.11, 95% CI − 0.63, 0.42, P = 0.69) and N stage [N0 (RR = 1.03, 95% CI 0.92, 1.15, P = 0.60), N1 (RR = 0.99, 95% CI 0.87, 1.14, P = 0.91), N2 (RR = 0.94, 95% CI 0.77, 1.15, P = 0.53)]. Conclusions SEMS implantation in patients with acute malignant obstructive colorectal cancer may lead to an increase in adverse tumor pathological characteristics, and these characteristics are mostly related to the poor prognosis of colorectal cancer. Although the adverse effect of SEMS on long-term survival has not been demonstrated, their adverse effects cannot be ignored. The use of SEMS as the preferred treatment for patients with resectable obstructive colorectal cancer remains to be carefully weighed, especially when patients are young or the surgical risk is not very high.

Emergency Resection

Introduction. Emergency resection represents the traditional treatment for left-sided malignant obstruction. However, the placement of self-expanding metallic stents and delayed surgery has been proposed as an alternative approach. The aim of the current meta-analysis was to review the available evidence, with particular interest for the short-term outcomes, including a recent multicentre RCT. Methods. We considered randomized controlled trials comparing stenting as a bridge to surgery and emergency surgery for the management of left-sided malignant large bowel obstruction, performing a systematic review in MEDLINE, PubMed database, and the Cochrane libraries. Results. We initially identified a total of 2543 studies. After the elimination of duplicates and the screening of titles and abstracts, seven studies, for a total of 448 patients, were considered. The current meta-analysis revealed no difference in the mortality rate between the stent group and the emergency surgery group; the postoperative complication rate (37.84% versus 54.87%, P=0.02), the stoma rate (28.8% versus 46.02%, P<0.0001), and the incidence of wound infection (8.11% versus 15.49%, P=0.01) were reduced after stent as a bridge to surgery. Conclusion. Colonic stenting as a bridge to surgery appears to be a safe approach to malignant large bowel obstruction. Possible advantages of this treatment can be identified in a reduced incidence of postoperative complications and a lower stoma rate. Further RCTs considering long-term outcomes and cost-effectiveness analysis are needed.
