Abstract

Background: In the world, colorectal cancer (CRC) is the cancer that is most likely to be diagnosed and the third largest cause of cancer-related mortality. Surgery is still the major treatment for colorectal cancer (CRC).

Objective: Before surgery, CT mesenteric angiography and intraoperative ICG were used to assess the sufficiency of vascular perfusion of the residual colon following left colic artery sparing to lower the risk of anastomotic leakage and maintain the same oncological outcomes.

Patients and Methods: A prospective research of patients treated between December 2021 and October 2023 at the surgical oncology department of Al-Azhar University and Al Salam Oncology Center, MOH, Egypt, for rectal and sigmoid colon cancer, using TME and sigmoid colectomy with CME.

Results: Due to tension-free anastomosis, the percentage of patients with CME in the LL group was significantly higher than in the HL group (30% & 0%, respectively), according to an analysis of the surgical specimens from both groups. Contrarily, there was a highly significant difference in the percentage of patients with TME in the HL group compared to LL (100% & 70%).

Conclusion: Further studies should be done as the long-term oncological outcome should be handled with more concentration. Reporting and sharing knowledge about the value of left colic artery preservation and use of intraoperative use of ICG for assessment of colorectal anastomosis to improve the overall results.
