Surgical Steps: Rectal Division
The rectal division can be performed laparoscopically or, alternatively, with robotic assistance (performed by advanced surgical teams after initial learning curve). The right lower quadrant robotic 8 mm cannula is switched to a 12 mm port and the stapler is introduced here. Align the rectum cephalad with the robotic instrumentation (in arms (2) and (3)) within the open stapler jaw. Clear communication with the patient-side assistant during this step is essential.

- Before dividing the rectum, one member of the team performs a digital rectal examination under direct visualization, and the distal margin is carefully assessed. A distal margin of at least 1 cm is targeted.
- Choose correct level of distal division:
- for cancers of the middle and lower rectum perform total mesorectal excision
- for upper rectal lesion divide the mesorectum at least 3-5 cm distal to the tumor (partial mesorectal excision)
- Divide the superior hemorrhoidal arteries in the posterior upper mesorectum and clear the fat surrounding this area.
- Switch the right lower quadrant robotic 8 mm cannula to a 12 mm port and introduce stapler (Endopath™ or roticulating Endo-GIA™).
- Align stapler at a right angle to the long axis of the rectum as much as possible.
- Align the rectum cephalad within the open stapler jaw.
- Divide the rectum by firing a stapler after a rectal washout is performed.
- If one cartridge of the stapler does not completely transect the rectum, fire a second cartridge and overlap the initial staple line.
- Move transected specimen into abdominal space and inspect pelvic space for bleeding.
