Abstract

Background: Self-expanding metallic stents (SEMS) have been acknowledged in management of acute colorectal obstruction. The surgical approach after SEMS insertion varies from open approach to laparoscopic-assisted approach. The primary objective of this study was to compare the outcomes of laparoscopic approach and open approach after SEMS insertion.
Methods:
From January 2007 to December 2010, cross-sectional medical records reviewed a total of 76 patients who underwent colorectal stenting with SEMS. Patients and tumor characteristics, complications, morbidity and mortality were obtained.
Results:
Forty-three patients underwent SEMS placement as a bridge to surgery. Laparoscopic-assisted surgery (LS) was performed in 24 patients (55.8%), and open surgery (OS) was performed in 19 patients (44.2%). All clinicopathological parameters were matched. The technical success of SEMS was found in 42 patients (97.7%), and the clinical stent success was 100%. LS had a higher chance of primary anastomosis than OS (p=0.012; Odd ratio 2.717; 95%CI: 1.79-4.012). LS had a lower permanent ostomy rate (p=0.031; Odd ratio 0.385; 95%CI: 0.259-0.572) and lower estimated blood loss (p=0.024; Odd ratio 0.23; 95%CI: 0.006-0.086). The post-operative complications, mortality rate, recurrence rate, disease free status, and overall survival rates between the two groups were non-significant. 
Conclusion:
Colonic stent is an effective treatment of acute malignant colonic obstruction. The authors suggest the advantage of laparoscopic approach resection after colonic stenting results in a higher primary anastomosis rate, and lower blood loss than open surgery.
