Clinical Trial Summary

Colorectal cancer is the second leading cause of death in the West, and rectal cancer accounts for about 25% of colon cancers Low anterior resection has been the mainstay of rectal cancer surgery in low rectal cancer since the 1970s. Although the best efforts of experienced surgeons, The local recurrence rate is 3 to 33% in conventional surgery, while total mesorectal excision (TME) results indicate a recurrence rate of less than 10% The evolution of the concept of TME which was first revealed by Heald.in 1982 made a major shift in the treatment strategies (Rodriguez-Luna et al,2015). The concept of TME was the most important event in surgery for rectal cancer in the last two decades, because even without a curative approach, the local recurrence decreased to 6 to 12%, and 5-year survival improved by 53-87% TME described clear definitions of distal resection margin (DRM), circumferential resection margin (CRM), and least number of harvested lymph nodes, so oncological outcomes improved, locoregional recurrence and survival rates also influenced . Laparoscopic total mesorectal excision (LTME) may be associated with less blood loss, earlier recovery, and lower morbidity. Identification of the small nerves and vessels became easiear because of laparoscopic magnified view of pelvis and thus prevents these injuries (Sajid et al, 2019). Also, minimal surgical trauma will reduce the immunologic response and preserves postoperative immunologic defenses. This may lead to low rate of infections as well as low local recurrences and distant metastases in addition to, tissue handling with less manipulation, 'may reduces the spread of cancer cells TME in obese males with low and anterior rectal tumors is technically challenging especially post neoadjuvant chemoradiotherapy due to distortion of the anatomical planes (Ng et al, 2014). In these patients, it is difficult to obtain a proper view of the dissection plane, in open technique which threatens the integrity of TME and carries the risk of positive margins, which is related to higher rates of local recurrence LTME is a widely used approach for rectal cancers; although conversion rate varies from 1.2 to 17%, and it is higher if BMI is equal to or more than 30
