Abstract

fetched live from OpenAlex

Endoscopic retrograde cholangiopancreatography and sphincterotomy is an established treatment for patients with common bile duct stones. Several techniques may be required. These include enlarging the bile duct orifice or dilating a stricture, reducing the size of the stones by various form of lithotripsy, or by temporary stenting. Stones greater than about 12 mm in diameter (the size of the scope on fluoroscopy) usually need to be fragmented to facilitate removal. There are several methods to achieve this endpoint: mechanical lithotripsy, extracorporeal shock wave lithotripsy, and intracorporeal lithotripsy, using cholangioscopy under electrohydraulic lithotripsy or laser lithotripsy. At endoscopy, an attempt to reposition the intrahepatic stones into the main hepatic duct or the larger lumen downstream biliary system can be made using a piston maneuver where the suction effect of an inflated extraction balloon below or above the stones may help dislodge and bring them into the main duct.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
