Abstract:

【Abstract】 Objective To explore the effect and safety of preservation of the left colic artery (LCA) for the treatment of sigmoid colon cancer. Methods A total of 75 cases with sigmoid colon cancer were included in the study and the clinical data were analyzed retrospectively. Of 75 cases, 32 underwent radical dissection with LCA preservation (LCA preservation group), the ones who underwent traditional surgery with cutting the root of inferior mesenteric artery were controls. The surgical effect, clinical pathological parameters and postoperative complications were compared between two groups. Results There were no differences in surgical time and blood loss between LCA preservation group and traditional group. The proximal bowel cut end (11.5cm vs 16.7cm) and distal bowel cut end (5.8 cm vs 8.7 cm) were both shorter in the LCA preservation group. We found no difference in the amount of postoperative harvested lymph nodes. The main group of harvested lymph nodes (2.3 vs 2.1) and positive lymph nodes (0.2 vs 0.3) were similar between two groups. We also found that the incidences of overall complications were similar between LCA preservation group and traditional group. Conclusion The application of LCA preservation for the treatment of sigmoid colon cancer was available, safe and effective and ensured radical dissection of lymph nodes along the root of inferior mesenteric artery, with no risk in improving surgical risk.
