Ascites after orthotopic liver transplantation in children
Bibliographic record
Abstract
Ascites is a poorly understood postoperative complication of orthotopic liver transplantation (OLT). It is associated with additional morbidity and can prolong hospitalization considerably. The incidence, the factors predictive of occurrence and the etiology of this complication are not known. The charts of 118 patients with 138 OLT were analyzed according to the following criteria: ascites lasting longer than the first 10 postoperative days, assessed by loss of ascitic fluid through drainage tubes, surgical wounds or paracentesis, with a peak volume of > or =10 mL/kg/day. Patients were divided into three groups: Group 1, no ascites; Group 2, ascites associated with postoperative complications, including chylus ascites; and Group 3, ascites not associated with postoperative complications. Postoperative ascites occurred in 43 of 138 OLT (31.2%). Patients with biliary atresia, preoperative portal hypertension, postoperative pleural effusion or at retransplantation had ascites significantly more often. In 32 of 138 (23.2%) OLT, ascites was associated with postoperative complications, including thrombosis, abdominal infections, intestinal perforation, biliary leak, pancreatitis, and chylus ascites. In 11 of 138 (7.9%) OLT, ascites was the only postoperative complication (group 3). Group three patients were significantly older, and had lower preoperative platelet counts and preoperative ascites more often than group 1 patients. The primary liver diseases were mainly cystic fibrosis of the pancreas, congenital hepatic fibrosis, and North American Indian childhood cirrhosis. The serum-ascites albumin gradient suggested a hepatic origin of ascites. Postoperative ascites is associated with the duration and degree of preoperative portal hypertension. We speculate that the mechanism involved includes a disproportion between venous blood volume and liver uptake capacity of the donor organ.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
