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
backgroundCholedochal exploration remains a reliable and effective therapeutic strategy for the management of choledocholithiasis. Nevertheless, the optimal approach to bile duct closure following exploration-specifically the choice between T-tube drainage and primary suture closure-remains controversial, with no clear consensus established in current surgical practice.
objectiveThis study aims to evaluate the safety and efficacy of self-detachable biliary stents in achieving primary closure following choledochotomy.Secondary research objective: Potential complications associated with the innovative surgical approach of using a self-dislodging biliary stent.
methodsFrom January 2021 to May 2023, a total of 112 patients diagnosed with choledocholithiasis were enrolled in this study. Among them, 60 patients were assigned to the TTD group, in which laparoscopic choledochotomy with T-tube drainage was performed, while 52 patients were included in the PDC group, receiving primary duct closure combined with placement of a self-detachable biliary stent. Postoperative outcomes were compared between the two groups, including operative time, time to first defecation, length of hospital stay, perioperative changes in hematological and liver function parameters, as well as the incidence of complications such as intra-abdominal hemorrhage, bile leakage, electrolyte disturbances, and wound infection.
resultsThere were no significant differences between the two groups with respect to operative time and intraoperative blood loss (P > 0.05). However, the time to first defecation and length of hospital stay were significantly shorter in the PDC group compared with the TTD group (P < 0.05). Postoperative WBC, TB, DB, and ALB levels did not differ significantly between the two groups (P > 0.05), whereas postoperative ALT, AST, and TBA levels were significantly different (P < 0.05). In addition, the overall incidence of postoperative complications was significantly lower in the PDC group than in the TTD group (P < 0.05).
conclusionLaparoscopic choledochal exploration followed by primary closure with a self-detachable biliary stent appears to be a safe, effective, and economically favorable strategy for the management of choledocholithiasis. This technique has the potential to serve as an alternative to conventional T-tube drainage, offering comparable safety while reducing postoperative complications and healthcare costs.
