Brief summary
Prospective multicenter randomized controlled trial comparing the prone vs. the supine position of the perineal time of the Miles operation in patients with advanced rectal cancer. Primary objective: \- Pathological circumferential resection margin Secondary objectives: * 5 year oncological outcomes * Morbimortality rates * Surgical specimen quality * Perineal hernia incidence
Interventions
Abdominoperineal extra-elevators rectal resection for low lying rectal cancer involving anal sphincter complex
Sponsors

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of the circumferential resection margin | 15-30 days after surgery date | Histopathological report of the circumferential resection margin of the surgical specimen obtained in patients that underwent perineal time of Miles procedure in prone vs supine position. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Histopathological quality of surgical specimen | 15-30 days after | Comparison of the quality of the surgical specimen in terms of integrity of the circumferential resection margin, accidental iatrogenic rupture etc. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Oncological outcomes | 5 years | Compare the incidence of local oncological disease, distance metastasis and survival in a 5 year follow up time span. |
| Morbidity of the perineal incision. | 1 day, 60 days ,1 ,2,3,4 and 5 years after surgery | Evaluation the clinical outcome of the perineal wound in terms of infection, dehiscence, perineal hernia etc. |
