Trial Identification

Brief Title: Study of NOTES-TME Versus L-LAR in Rectal Cancer

Official Title: Multicenter Prospective Randomized Controlled Study of the Transanal Total Mesorectal Excision Versus Laparoscopic Low Anterior Resection in Rectal Cancer

Study ID: NCT02550769

Conditions

Rectal Cancer

Interventions

TRANSANAL TOTAL MESORECTAL EXCISION

Laparoscopic-LAR

Study Description

Brief Summary: INTRODUCTION: Transanal TME (T-TME) combined with laparoscopy, called hybrid-NOTES, is a less invasive procedure that responds to some of the limitations of the rectal laparoscopic approach. MAIN OBJECTIVE: To analyze that the T-TME gets a faster recovery due to a lower conversion rate to open surgery than laparoscopic low anterior resection (L-LAR) in rectal cancer with the same pathological, functional and oncologic results. METHODOLOGY: A prospective multicenter randomized controlled study of patients with rectal cancer that, were randomized in the T-TME- and L-LAR group. The main variables are: general morbidity, anastomotic dehiscence, conversion rate to open surgery and hospital stay. The sample calculation is 58 patients per group.

Detailed Description: INTRODUCTION: The laparoscopic total mesorectal excision (TME) has provided better patient recovery with less morbidity and shorter hospital stay compared with open surgery. However in laparoscopic low rectal surgery, overall conversion to open surgery is around 20%. Transanal TME (T-TME) combined with laparoscopy, called hybrid-NOTES, is a less invasive procedure that responds to some of the limitations of the rectal laparoscopic approach. MAIN OBJECTIVE: To analyze that the T-TME gets a faster recovery due to a lower conversion rate to open surgery than laparoscopic low anterior resection (L-LAR) in rectal cancer with the same pathological, functional and oncologic results. METHODOLOGY: A prospective multicenter randomized controlled study of patients diagnosed with adenocarcinoma of the rectum that after inclusion and exclusion criteria, were randomized in the T-TME- and L-LAR group. The main variables are: general morbidity, anastomotic dehiscence, conversion rate to open surgery and hospital stay. The other variables studied were: demographic, surgical, pathological, 30-day morbidity and mortality, quality of life and oncologic results. The sample calculation is 53 patients per group. With an estimated loss of 10%, the final number will be 116 patients.
