OBJECTIVES: To determine the effectiveness and safety of the utilization of emergency colonic stenting with the use of self-expanding metallic stents versus conventional open surgery in patients presenting with acute left bowel obstruction secondary to malignancy.
SEARCH METHODS: The investigator did a literature search on several medical databases namely: Pub Med, EBSCOHost, ScienceDirect and manual search to look for studies that pertain on the use of SEMS in comparison to open surgery in patients presenting with acute left sided bowel obstruction. Search terms included: Self-expanding metallic stents, conventional or open surgery, left sided obstruction, and malignancy.
SELECTION CRITERIA: Randomized control studies of were included in this study. Studies that involved the use of SEMS in comparison with open surgery in patients presenting with acute left sided malignant bowel obstruction were included in this review.
DATA COLLECTION AND ANALYSIS: Statistical Analysis with the use of Review Manager 5.3 was done in this review.
MAIN RESULTS: Two randomized control studies were included in this study. The study showed a significant difference between the control and experimental group in terms of one stage stoma rates, follow-up stoma rates and morbidity in favor of the experimental group. However, the study was not able to determine any significant difference between the two in terms of mortality, as well as the occurrence of procedure related complications such as leaks and abscess.
CONCLUSIONS: Colonic stenting appears to be an effective treatment of acute left-sided malignant large bowel obstruction, as it provides less number of stoma rates and less morbidity, with no significant increase in procedure related complications and mortality compared to conventional open surgery.
