Single-port robotic cholecystectomy using the da Vinci SP system versus single-port laparoscopic cholecystectomy: comparative clinical outcomes.
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionSingle-port surgery has been emphasized, with a focus on its technical challenges, patient satisfaction, and advances in the field, especially since the advent of single-port robotic systems. Our aims in this study were to compare the clinical outcomes of single-port cholecystectomy between the laparoscopic and robotic da Vinci SP approaches. MATERIALS AND
methodsWe analyzed data from patients who underwent single-port cholecystectomy for symptomatic gallstones or gallbladder polyps. We compared 176 patients who underwent single-port laparoscopic cholecystectomy with 243 patients who underwent single-port robotic cholecystectomy.
resultsOperation time, conversion rate, confirmation rate of a critical view of safety, complication rate, and pathologic results did not differ significantly between the two groups. The mean operative time was comparable between both groups (59.0 ± 36.1 vs 54.3 ± 22.9 min, p = 0.134). Hospital stay was shorter in the robotic group, although it was not significant after adjustment. The robotic group showed significantly lower postoperative pain scores and reduced opioid use. Although the robotic group included more cases with inflammatory or adhesive changes, the rate of achieving a critical view of safety and the overall complication rate did not differ between groups. Gallbladder perforation occurred more frequently in the laparoscopic group. Bile duct-related complications were rare and successfully managed by endoscopic retrograde cholangiopancreatography.
conclusionWe conclude that single-port robotic cholecystectomy and single-port laparoscopic cholecystectomy are both feasible and safe surgical techniques. However, single-port robotic cholecystectomy has clinical advantages, primarily lower postoperative pain and a reduced analgesic requirement than the laparoscopic technique.
