Ergonomic wedge pillow to reduce neck pain after prone ERCP; a randomized, controlled study.
Trial report in Surgical endoscopy, 2025. 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
backgroundProne positioning during endoscopic retrograde cholangiopancreatography (ERCP) can lead to post-procedure neck pain due to increased cervical spine stress and prolonged muscle stretching. This study aimed to evaluate the efficacy and satisfaction of an ergonomic wedge pillow for patients undergoing prone ERCP.
methodsPatients indicated for ERCP were randomized 1:1 to a study group (with the pillow) or a control group. Neck pain was assessed before ERCP and at 1 h, 1 day, and 7 days post-procedure by blinded assessors. Endoscopists rated scope intubation difficulty and satisfaction with the pillow. The need for patient shoulder lifting during intubation was also recorded.
resultsA total of 256 patients were randomized to the study group (128 patients), and the control group (128 patients). The baseline characteristics were not different between the two groups. The prevalence of post-procedural neck pain at 1 day was significantly lower in the study group (19%) than the control group (30%) (p = 0.040), especially for moderate-to-severe neck pain (4% vs 11%, respectively) (p = 0.032). The study group had a lower difficulty score of scope intubation and required less shoulder lifting during scope intubation (9% vs 22%, respectively) (p = 0.002). Endoscopists' satisfaction scores were significantly higher in study group than the control group (9.6 vs 8.9, respectively) (p < 0.001).
conclusionAn ergonomic wedge pillow for prone ERCP reduced moderate-to-severe pain at day 1 after ERCP, difficulty of scope intubation, and the requirement of shoulder lifting during procedure. Moreover, this ergonomic pillow had a higher endoscopists' satisfaction score than the control group.
