Transcholecystic management of extrahepatic duct stones in poor candidates for endoscopic or transhepatic approaches.

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
objectivesTo investigate transcholecystic management of extrahepatic duct (EHD) stones using balloon ampulloplasty in patients who are poor candidates for endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic biliary drainage (PTBD) and assess its efficacy and safety.
methodsForty-one patients who were unable to undergo ERCP or had failed ERCP with non-dilated intrahepatic ducts (IHD) between February 2019 and October 2020 were retrospectively enrolled. After clinical improvement with percutaneous cholecystostomy (PC), EHD stones were managed through cystic duct passage, guidewire unwinding, sheath insertion, and EHD stone removal using balloon ampulloplasty. If the transcholecystic route failed, a transhepatic approach was used according to the pre-existing cholangiogram obtained via PC. We evaluated the technical success rate and complications of each step.
resultsThe technical success rate for the transcholecystic-only approach was 80.5%. The remaining cases were successfully managed with transhepatic conversion. Multiple stone removal sessions were required in 22% of the cases. One patient with combined IHD stones was initially converted to a transhepatic approach without any transcholecystic removal trial. The technical success rates for each step were as follows: cystic duct passage (38/40, 95%), guidewire unwinding (36/38, 94.7%), sheath insertion (36/36, 100%), and stone removal using balloon ampulloplasty (33/36, 91.7%). The overall clinical success was 97.6% (40/41) without major procedure-related complications. Thereafter, cholecystectomy was successfully performed in patients with concomitant gallstones (n = 20). No postprocedural complications occurred during the follow-up (1-70 days).
conclusionsPercutaneous EHD stone removal through transcholecystic and transhepatic routes after PC is effective and safe in poor candidates for PTBD or ERCP. KEY POINTS: • This study shows the safety and efficacy of extrahepatic duct (EHD) stones in patients who are poor candidates for initial percutaneous transhepatic biliary drainage and endoscopic retrograde cholangiopancreatography. • The overall technical success for the transcholecystic-only approach was 80.5% (33/41). Including transhepatic conversions, it was 100% (41/41). Stone removal was successful in one session in 78% (32/41) of the patients and in multiple sessions in 28.1% (9/41) of the patients. • Balloon ampulloplasty with stone expulsion using an occlusion balloon catheter is also a safe and effective method for removing EHD stones.
