PURPOSE:To compare the intraoperative and postoperative outcomes between right laparoscopic colectomy (RLC) and left laparoscopic colectomy (LLC) for colon cancer.METHOD:Patients who underwent elective RLC or LLC for colon cancer between January 2004 and December 2014 were identified and elected for a retrospective analysis. Primary outcomes were technical difficulty (including operative time, intraoperative complications, and conversion rate) and postoperative outcome (including postoperative complications, length of hospital stay, reinterventions, readmissions, and mortality).RESULTS:A total of 547 patients (mean age: 68.5 years old; 48.4% males) were analyzed. The RLC group had a higher mean age (71 vs 65; p < 0.001), ASA 3/4 grade (36 vs 26%; p = 0.02), and comorbidity rate (61 vs 48%, p = 0.003). Regarding technical difficulty, no difference was found between the groups in intraoperative complications (4.1 vs 5.9%; p = 0.34) or conversion rate (6.2 vs 3.9%, p = 0.24). Mean operative time was significantly shorter for RLC (162 vs 185 min, p < 0.001). Regarding postoperative outcome, the RLC group had a higher overall morbidity (20.5 vs 13.3%, p = 0.03), ileus (10.6 vs 2.4%, p < 0.001), and a longer hospital stay (4.7 vs 3.9 days, p = 0.003), with no differences regarding reoperations, readmissions, or mortality. The multivariate analysis showed that RLC were independently associated with a longer operative time and postoperative ileus.CONCLUSIONS:RLC for colon cancer was independently associated with a shorter operative time, an increased risk of ileus, and a longer hospital stay than left laparoscopic colectomy in high-volume centers.
