Abstract
BACKGROUND: The incidence of gallstones is higher in people who have undergone gastrectomy than in the general population, but the cause of this is unknown. METHODS: Between January 1992 and January 2003, 749 patients underwent ultrasonography of the gallbladder after gastrectomy for gastric cancer. A total of 2327 examinations were carried out. The incidence of gallstones was compared in subgroups of patients classified according to the type of reconstruction, extent of gastrectomy, whether the duodenum was excluded and type of lymph node dissection. RESULTS: The incidence of gallstones was significantly higher after total compared with partial gastrectomy (27.9 versus 7.8 per cent at 5 years; P < 0.001). Reconstruction with duodenal exclusion was associated with a significantly higher incidence than non-exclusion (25.1 versus 8.2 per cent at 5 years; P < 0.001). Patients who had lymph node dissection in the hepatoduodenal ligament had a significantly higher incidence of gallstones than those who did not (28.2 versus 7.5 per cent at 5 years; P < 0.001). In multivariate analysis that included type of reconstruction and lymph node dissection, lymph node dissection in the hepatoduodenal ligament was identified as the most significant risk factor for gallstone development (odds ratio 3.66 (95 per cent confidence interval 2.16 to 6.22); P < 0.001). CONCLUSION: Lymph node dissection in the hepatoduodenal ligament, total gastrectomy and exclusion of the duodenum are risk factors for gallstones after gastrectomy.

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 it
