ABSTRACT
BACKGROUND:
During sigmoid or rectal cancer surgery, dissection of lymph-nodes at the origin of inferior mesenteric artery is mandatory. Nevertheless, ligation of the origin of IMA should compromise blood supply to left colon and affect anastomosis. The aim of this retrospective evaluation is to compare high IMA ligation and low IMA ligation with preservation of LCA and skeletonization of the origin of IMA during laparoscopic colorectal resection.METHODS:
All 120 patients included were affected by clinically M-0 sigmoid or rectal cancer. A laparoscopic colorectal resection with low or high ligature of IMA was performed. Low ligation was carried out with lymphadenectomy of the arterial root. Patients were divided in 2 groups according to type of treatment Group A, high IMA ligation (N=65), Group B, low ligation with lymphadenectomy of IMA root (N=55).RESULTS:
Preoperatively 59 patients had stage I, 42 patients had stage II and 19 patients had stage III tumor. A mean of 20.3 +/- 4.5 lymph nodes were removed in group A patients and 18.9 +/- 9.1 in group B patients, and this difference was not statistically significant. Operative time, intraoperative and postoperative complication rates were not different between the two group.CONCLUSIONS:
Low IMA ligation combined with lymph-node dissection at its origin is safe and effective, not time consuming and not associated to increased risk of complications and nerve damage. This technique can be considered as alternative to standard high IMA ligation in selected patients.Palavras-chave
