Clinical and Economic Outcomes of Using Robotic Versus Hand-Held Staplers During Robotic Lobectomy

During robotic lobectomy (RL), the surgeon can elect to use either robotic staplers or hand-held laparoscopic staplers. It is assumed that either will result in similar outcomes, while robotic staplers increase cost. We sought to compare perioperative outcomes and costs between RL cases that utilized robotic staplers versus hand-held staplers in real-world clinical practice.

Patients who underwent an elective RL between October 2015 and December 2017 were identified in the Premier Hospital Perspective Database. Propensity score matching (PSM) analysis was performed to compare perioperative outcomes, healthcare resource utilization, and costs between cases using robotic staplers and hand-held staplers during RL.

In the PSM analysis, RL cases that fully utilized robotic staplers compared to hand-held staplers were associated with significantly lower risks of developing bleeding (5.6% vs 9.8%, P = 0.03) and conversion to open surgery (0.3% vs 5.9%, P = 0.004). Additionally, in a multivariable regression analysis, robotic stapler was associated with reduced risk for air leak (OR 0.70, 95% CI 0.50-0.98) and overall complications (OR 0.76, 95% CI 0.58-0.99). The total index hospitalization costs were comparable between the 2 groups (median [IQR], $21,667 [$16,860-$29,033] in robotic stapler vs $21,398 [$17,258-$29,406] in hand-held stapler, P = 0.22).

Among RL cases, utilization of robotic staplers was associated with significantly lower risks of perioperative bleeding, conversion, and possibly air leak and overall complications compared to RL cases utilizing hand-held staplers. The choice of stapler may have an impact on outcomes and robotic staplers do not increase total costs.
