Abstract
BACKGROUND: Esophageal anastomotic leak is a potentially life threatening complication of esophagectomy and esophagogastrectomy. We reviewed our experience with this complication and tried to identify factors predictive of mortality after esophageal anastomotic leak. METHODS: Records of patients undergoing esophagectomy and esophagogastrectomy for benign or malignant disease over a 10-year period (1989-1999), who developed esophageal anastomotic leaks, were reviewed. RESULTS: Three-hundred and seven patients underwent esophagectomy or esophagogastrectomy. Twenty-three (7.5%) developed esophageal anastomotic leaks. Eight of these patients (35%) died. Four of 23 (17%) patients had seemingly normal postoperative contrast studies. Factors potentially predictive of death included age (died, 72.8+/-8.3 years; survived, 65.3+/-8.8 years; p=0.063), location of anastomosis (cervical, 3/9 died; thoracic, 5/14 died; p=0.91), leak presentation (clinical, 6/12 died; contrast study, 2/11 died; p=0.11), time of leak (<7 days, 3/5 died; > or =7 days, 5/18 died; p=0.18), presence of gastric necrosis (necrosis, 3/3 died; no necrosis, 5/20 died; p=0.019), and treatment (surgical, 4/4 died; conservative, 4/19 died; p=0.005). CONCLUSIONS: Postoperative esophageal anastomotic leaks prove fatal in a significant number of cases. The lethal potential of cervical anastomotic leaks should not be underestimated. Gastric necrosis is an important predictor of subsequent death. Advanced age, early postoperative (<7 days) leakage, and clinically apparent signs of leakage may be predictive of death but these factors did not reach statistical significance in our study. Surgical treatment of esophageal anastomotic leaks is associated with subsequent death, but this relationship is unlikely to be causal; severely ill patients tend to be treated surgically.

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
