Evaluation of the Distal Resection Margin Vascularity in the Superior Rectal Artery Preservation in Sigmoidectomy for Sigmoid Colon Cancer

Abstract

Background: Colorectal surgery has gained wide acceptance, especially in the treatment of cancer colon. Several techniques and modifications have been proposed to improve morbidity and mortality associated with left hemicolectomy.Objective: To evaluate the technique of superior rectal artery preservation in sigmoidectomy for sigmoid colon cancer, as regard impact on both radicality and vascularization in the remaining rectum.Patients and Methods: A prospective study had been conducted on Bab El Sharia University Hospital and El-Sahel Teaching Hospital from March 2019 to March 2020. Thirty patients who are posted for sigmoidectomy with preservation of superior rectal artery had been included in the study.Results: That mean of intraoperative blood loss was 35.64 ml and 6.7% of patients have intraoperative bleeding. The mean of harvested lymph nodes was 19.27. One patient needed conversion to open surgery. As regard mean of operation time, it was 190.73 min. Conclusion:Superior rectal artery preservation sigmoidectomy for colon cancer was a beneficial technique guarding against post-operative anastomosing leakage, important oncologic principles as lymph node (LN) metastasis and recurrence should be taken in consideration should be kept in mind before performing that procedure.
