Background
In sigmoid cancer, both inferior mesenteric artery high or low ligations are accepted for curative purposes. Since inferior mesenteric artery ligation could compromise blood flow to the anastomosis, potentially increasing anastomotic leakage onset, real oncological benefits and possible disadvantages related to vascular transection level are still on debate. We introduce totally laparoscopic inferior mesenteric artery peeling technique to release from the concept of lymph nodal harvesting linked to arterial transection level.
Methods
Over a period of 24 months, 31 patients presenting with sigmoid cancer were submitted to laparoscopic sigmoidectomy associated with inferior mesenteric artery peeling. Data on intraoperative and postoperative outcomes have been prospectively collected.
Results
Mean operative time was 180 min (range 110–330 min); mean intraoperative blood loss was 60 ml (range 30–150 ml), and mean postoperative hospitalization was 6.2 days (range 4–11 days). Mean number of lymph node harvested was 16.7 (range 12–28).
Conclusions
Given a proper selection of patients, laparoscopic sigmoidectomy comprehensive of sub-adventitial IMA skeletonization from its aortic origin could provide good oncological outcomes and recanalization rate. Further data are advocated to confirm these preliminary results.
