Abstract
BACKGROUND: We conducted an objective followup of 181 patients after laparoscopic Nissen fundoplication during a 5-year period after surgery. STUDY DESIGN: Patients underwent 24-hour pH recording, esophageal manometry, and symptom score assessment for six gastroesophageal reflux disease symptoms preoperatively and at 6 months, 2 years, and 5 years after surgery. RESULTS: Laparoscopic fundoplication was associated with a significant (p < 0.0001) increase in lower esophageal sphincter pressure and a significant (p < 0.0001) drop in duration of acid reflux in 24 hours, and symptom score, 6, 24, and 60 months after surgery when compared with preoperative values. Twenty-one patients (12%) have experienced recurrence of reflux-type symptoms, but only six have required repeat surgery. Lower esophageal sphincter tone dropped between 6 months and 5 years after surgery, but was still an effective antireflux barrier. Patient satisfaction with surgery dropped over the 5-year followup but remained high, at 86%, after 5 years. CONCLUSIONS: Laparoscopic Nissen fundoplication remains an effective antireflux procedure at 5 years.

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
