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
Background Laparoscopic bile duct exploration (LBDE) enables single-stage management of common bile duct (CBD) stones. However, large or impacted stones often necessitate choledochotomy, which is associated with increased morbidity and longer operative duration. In 2025, routine intraoperative lithotripsy was introduced in our unit to facilitate trans-cystic stone clearance. Aim To evaluate the impact of routine intraoperative lithotripsy on operative approach and perioperative outcomes by comparing cases performed in 2025 with those performed between 2020 and 2024. Methods A retrospective cohort study was conducted of all consecutive patients undergoing LBDE between January 2020 and December 2025 at a single upper gastrointestinal surgical unit. Patients were divided into two groups: pre-lithotripsy era (2020-2024) and lithotripsy era (2025). The primary outcome was the rate of choledochotomy. Secondary outcomes included operative time, bile leak, endoscopic retrograde cholangiopancreatography (ERCP) reintervention, and length of stay. Categorical variables were compared using chi-square testing and continuous variables using Mann-Whitney U testing. Results A total of 301 patients were included (2020-2024: n=225; 2025: n=76). The choledochotomy rate decreased significantly following the introduction of lithotripsy (34.2% (n=77) vs 5.2% (n=4), p<0.001). Median operative time reduced from 159 minutes to 120 minutes (p=0.005). No bile leaks occurred in 2025 compared with 2.7% (n=6) in the earlier cohort (p=0.335). There were no significant differences in ERCP reintervention (7.6% (n=17) vs 5.3% (n=5.3), p=0.75) or length of stay (median 2 vs 3 days, p=0.14). Conclusion Routine intraoperative lithotripsy significantly reduced the need for choledochotomy and shortened operative duration. Its introduction has transformed surgical strategy toward near-universal trans-cystic completion with fewer post-operative complications.
