Aim of the study: This European multicenter study aims to compare the results of laparoscopic versus laparotomy approach for the resection of splenic flexure colon carcinoma (SFC).
Patients and methods: Patients with SFC who required curative resection by laparoscopy (LAP) or laparotomy (OPEN) between 2000 and 2018 were included. Three types of interventions were considered: extended right hemi-colectomy, left hemi-colectomy and splenic flexure resection. The LAP and OPEN groups were matched according to propensity score and compared with Chi-square, Mann-Whitney tests, and multivariate regression models. Overall survival and recurrence-free survival were assessed using the Kaplan-Meier method.
Results: The study population consisted of 399 patients, including 297 operated by LAP and 102 by OPEN. Extended right hemi-colectomy was performed in 35.8% of cases, left hemi-colectomy in 32.8% and splenic flexure resection in 31.4%. After propensity score matching, the LAP (n=64) and OPEN (n=64) groups were comparable for all pre-operative variables and tumor characteristics. The LAP group showed less blood loss and a shorter interval to return of transit and feeding compared to the OPEN group, regardless of the resection technique. There were no differences between the groups in terms of overall survival and 5-year recurrence-free survival.
Conclusion: These results support the application of laparoscopy for the resection of SFC.
