Open or Laparoscopic Mesolectal Excision in Low Rectum Cancer

Total Mesorectal Resection With Dissection of the Lateral Pelvic Lymph Nodes in Low Advanced Cancer Rectum Patients; Laparoscopic Versus Open Approach

To compare the open approach and the laparoscopic-assisted approach of dissection of lateral lymph nodes in low advanced rectal cancer patients with clinically suspected nodal metastases in terms of safety, technical feasibility, and patient's oncological outcomes.

the investigators collected data of sixty low advanced cancer rectum patients who underwent either laparoscopic (30 cases) or open total mesorectal excision (30 cases) in addition to lateral pelvic dissection. The duration of operation in the laparoscopically assisted procedure was longer than the open procedure (p=0.003). The postoperative hospital stay time was longer in the open group than in the laparoscopic group (P=0.043). No significant differences between both groups regarding the number of excised lymph nodes, disease recurrence, RFS, or OS rate.

Inclusion Criteria:

• Patients aged from 20-70 years with
• Sure diagnosis of locally advanced (T3 and T4) adenocarcinoma located in the middle or lower part of the rectum
• Clinical or radiological evidence of lateral pelvic lymph nodes metastases

Exclusion Criteria:

• Patients refused to be included in the study,
• Patients with concurrent primary cancer in other locations
• Patients with recurrent cancer after treatment
• Patients with distant metastasis
• Previously managed for pelvic cancer
