Robotic-assisted Versus Conventional Laparoscopic Approach for Rectal Cancer Surgery

In the researchers' words

This is a prospective randomized controlled study that was conducted on patients of both sexes and definite age group at National Cancer Institute-Egypt and with adenocarcinoma of the rectum located within 15 cm from the anal verge. Tumor localization was categorized as the upper rectum (distal border of tumor is from 10 to 15 cm from the anal verge), middle rectum (5 to 10 cm from the anal verge) or lower rectum (less than 5 cm from the anal verge) as measured by colonoscopy and digital rectal examination. Patients were classified into two groups; robotic assisted rectal surgery and conventional laparoscopic rectal surgery.Baseline demographics (gender, age, ASA, BMI), preoperative data (distance of the tumor from the anal verge, clinical stage, whether preoperative chemoradiation (CRT), presence of residual tumor after CRT, intraoperative data (preparation time, actual operative time, estimated blood loss, conversion rate to open surgery), postoperative data (pathological stage, number of harvested lymph nodes, macroscopic completeness of resection in the form of proximal margin, distal margin, circumferential radial margin) and immediate postoperative outcome within one month (days of return of bowel function, days of hospital stay, complications, if any, like anastomotic leakage, ileus,wound problems and others, rate of re-operation, rate of readmission \& 30-days…
