Introduction: We previously conducted a randomized trial comparing the endo-laparoscopic approach (i.e. placing self-expanding metallic stents followed by laparoscopic resection) and conventional open surgery in the treatment of obstructing left-sided colon cancer. This study is a follow-up of the previous randomized trial and aims to report the long-term outcomes of the two groups. Methods: Forty-eight patients from the randomized trial were followed up in an outpatient clinic with regular monitoring. Patients were compared for clinicopathological variables, disease recurrence and survival rates.Results: Clinicopathological details were comparable between the two groups. During the median follow-up periods of 32 months for the open group and 65 months endo-laparoscopic group, no statistically significant difference was observed between the groups in disease recurrence rate, 5-year overall survival (27% vs 48%, P = 0.076) and 5-year disease-free survival rates (48% vs 52%, P = 0.63). Conclusion: Besides being a safe bridge to subsequent elective laparoscopic surgery, preoperative self-expanding metallic stents insertion does not adversely affect oncological outcomes and patient survival. Based on our data, the endo-laparoscopic approach is the treatment of choice for patients presenting with malignant left-sided colonic obstruction.
Both THD and TST are safe, and they appear to have similar short-term outcomes; however, TST is associated with better improvement in symptoms, lower recurrence rates and greater patient satisfaction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
