Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome variables will be measured using data held in pre-existing databases at each of the participating sites from rectal cancer patients who underwent robotic total mesorectal excision (TME) surgery at one timepoint: 1. Length of stay in days after surgery 2. Operative time in minutes 3. Blood loss in millilitres | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary outcome variables will be measured using data held in pre-existing databases at each of the participating sites from rectal cancer patients who underwent robotic total mesorectal excision (TME) surgery at one timepoint: 1. Intraoperative and postoperative complications recorded as timepoint, type of complication, and Clavien-Dindo classification grading of complication 2. Reinterventions and readmissions after surgery recorded as yes/no and timepoint 3. Pathological outcomes recorded as the number of positive lymph nodes, differentiation grading, quality of the specimen, and positivity of circumferential resection margins 4. Stoma formation as yes/no and type, as well as reversal of stoma and timepoint of reversal 5. Local recurrence of disease as yes/no and timepoint 6. Distant recurrence of disease as yes/no, timepoint, and location of recurrence 7. Disease-free survival as yes/no and timepoint 8. Overall survival as yes/no and timepoint | — |
