Effects of extremely low-pressure pneumoperitoneum on postoperative recovery after single site robot-assisted cholecystectomy: a randomized controlled trial.
Trial report in Langenbeck's archives of surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeA robotic platform has enabled extremely low-pressure pneumoperitoneum (ELPP, 4 mmHg) to reduce surgical insults to human physiology during a minimally invasive surgery. The objective of this study was to investigate the effect of ELPP in single-site robotic cholecystectomy (SSRC) on postoperative pain, shoulder pain, and physiological changes during surgery compared to a standard pressure pneumoperitoneum (SPP, 12-14 mmHg).
methodsA total of 182 patients who underwent an elective cholecystectomy were randomized into an ELPP SSRC group (n = 91) and an SPP SSRC group (n = 91). Postoperative pain was assessed at 6, 12, 24, and 48 h after surgery. The number of patients complaining of shoulder pain was observed. Intraoperative changes of ventilatory parameters were also measured.
resultsPostoperative pain scores (p = 0.038, p < 0.001, p < 0.001, and p = 0.015 at 6, 12, 24, and 48 h after surgery, respectively) and the number of patients with shoulder pain (p <0.001) were significantly lower in the ELPP SSRC group than in the SPP SSRC group. Intraoperative changes in peak inspiratory pressure (p < 0.001), plateau pressure (p < 0.001), EtCO
conclusionThe ELPP during robotic cholecystectomy could significantly relieve postoperative pain and shoulder pain. In addition, the ELPP can reduce changes in lung compliance during surgery and the demand for postoperative analgesics, thereby improving the quality of life of patients during early stages of postoperative rehabilitation.
