Acute Cholecystitis and Cholelithiasis Developed after Esophagectomy
Bibliographic record
Abstract
BACKGROUND: Although the prevalence of gallstone disease after gastrectomy is reported to be high, its prevalence after esophagectomy is scarcely reported. MATERIALS AND METHODS: Gallbladder disease following an esophagectomy was prospectively evaluated in 237 patients with esophageal cancer by abdominal ultrasonography twice a year up to five years postoperatively. The median follow-up period was 18.6 months. RESULTS: One patient (0.4%) developed acute acalculous cholecystitis postoperatively, and 13 patients (5.5%) developed gallstone disease during the follow-up period. Nine (69%) of these 13 patients developed gallstone disease within two years, and another two patients developed the disease three years after esophagectomy. Another patient developed gallbladder debris at 35 months postoperatively, and one developed gallbladder polyps at 33 months. Seven of the 13 patients with gallstone disease underwent cholecystectomy between 13 and 125 months after esophagectomy: two developed acute cholecystitis; two had associated common bile duct stones; the remaining three patients had upper abdominal pain. Nine of the 13 patients who developed gallstone disease showed a history of alcoholism, whereas only 81 of 224 patients without gallstone disease had a similar history (P<0.05). CONCLUSION: A certain number of patients with esophageal carcinoma and a history of alcoholism develop cholelithiasis within three years after esophagectomy, and subsequently undergo cholecystectomy during the follow-up period.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
