Robotic cholecystectomy tied to fewer complications but higher cost

A retrospective study across 8 hospitals compared robotic (RC) and laparoscopic cholecystectomy (LC) in 1828 patients, using the Nassar score to adjust for procedure difficulty. The study reported that RC was associated with lower rates of adverse outcomes (conversion or Clavien-Dindo grade 3+ complication) and shorter length of stay overall, with the greatest benefit in high-risk patients and those with elevated BMI, but RC was associated with higher total variable cost across all risk strata. The authors developed a risk calculator (AUC 0.744-0.750) they state may assist in selecting operative approach.

Most relevant for: Patients undergoing minimally invasive cholecystectomy, particularly those with high preoperative difficulty scores or elevated BMI.
