Design outcomes

Primary

MeasureTime frame
The occurrence of conversion to open or laparoscopic surgery Details of intrasurgical complications, rectal, colon injury, vessel injury, bladder/ureter injury, and nerve injury Details of postoperative complications, such as type of condition, severity based on Clavien-Dindo classification, time of onset, treatment, outcome, and causal relationship

Secondary
