Short-pitch transection technique described for robotic liver resection
A retrospective single-center cohort compared perioperative outcomes in 105 patients undergoing robotic liver resection (RLR) and 190 undergoing laparoscopic liver resection (LLR) from 2019 to 2025. The authors describe a “short-pitch dividing” technique for robotic parenchymal transection; the RLR group had no bile leaks and a shorter median hospital stay, although the comparison cannot establish that the technique caused these outcomes.
- Single-center retrospective comparison included 105 RLR and 190 LLR cases.
- No bile leaks were reported in the RLR group.
- Median hospital stay was four days after RLR versus six after LLR.
- The design cannot attribute outcome differences to the technique.
Robotic liver resection can be challenging because surgeons lack tactile feedback and a dedicated robotic ultrasonic aspirator. Researchers at the University of Tokyo retrospectively reviewed consecutive liver resections performed from 2019 to 2025, comparing 105 RLR cases with 190 LLR cases. They describe a short-pitch dividing method using Maryland bipolar forceps: the closed tip is inserted into the parenchyma and slightly opened in repeated motions. The method was combined with two-handed transection and five auxiliary strategies.
Intermediate- or high-complexity resections were more frequent in the RLR group than in the LLR group (45.8% vs 31.9%; P=0.043). No bile leaks were reported after RLR, compared with six cases (3.1%) after LLR. Median postoperative hospital stay was four days after RLR and six days after LLR (P<0.001).
These findings describe one center’s experience and do not establish that the transection method itself reduced complications or length of stay. The retrospective, non-randomized comparison may be affected by differences in patient selection, surgical approach and changes in practice over time. The supplied report does not provide a direct comparison isolating outcomes attributable to the technique.
