Brief Summary
A randomized, controlled clinical trial comparing lymphadenectomy with extended inferior mesenteric artery ligation (complete mesocolon excision: which includes lymphoma tissue from the origin of the inferior mesenteric vein) with conventional locoregional lymphadenectomy in patients undergoing laparoscopic sigmoidectomy for sigmoid cancer.

Study Arms (2)
Complete Mesocolon Excision
EXPERIMENTALA high tie of the inferior mesenteric artery (IMA) should be attempted. The inferior mesenteric vein section at the Treitz angle should be performed. The lymphatic tissue that accompanies the inferior mesenteric vein should be added.
Conventional Locoregional Lymphadenectomy
ACTIVE COMPARATORA high tie of the inferior mesenteric artery (IMA) should be attempted. Lymphadenectomy of the lymphatic tissue that accompanies the IMA will be performed. The inferior mesenteric vein section could be performed at the discretion of the surgeon.
Interventions
Laparoscopic sigmoidectomy with lymphadenectomy of the lymphatic tissue that accompanies the inferior mesenteric vein and a high tie ligation of the inferior mesenteric artery (complete mesocolon excision)
Laparoscopic sigmoidectomy with lymphadenectomy of the lymphatic tissue that accompanies the inferior mesenteric artery and a high tie ligation of the inferior mesenteric artery with or without section of inferior mesenteric vein.
Eligibility Criteria
You may qualify if:
- Patients undergoing programmed surgery for laparoscopic sigmoid colon cancer.

- Colon cancer located in the right colon, transverse, splenic or non-sigmoid left colon.
- Metastatic disease (M1).
- History of colorectal cancer surgery, different from a local excision.
- Inflammatory bowel disease with anatomopathological confirmation.
- Patients with psychiatric illness, addiction or any disorder that impedes the understanding of informed consent.
