Effect of Laparoscopic Failure on Outcome of Laparoscopic Nissen Fundoplication: Independent Review
Bibliographic record
Abstract
PURPOSE: This study was undertaken to determine whether conversion or early reoperation contributed significantly to the eventual outcome of laparoscopic Nissen fundoplication. PATIENTS AND METHODS: An independent surgeon, blinded to the operative events, administered two general and one system-specific quality of life tools to the first 100 consecutive patients booked for laparoscopic fundoplication in a community hospital, where the open conversion rate was 4 patients/surgeon and the early reoperation rate 1.5 patients/surgeon for the first 20 operations. Patients were also asked about need for medication, dysphagia, satisfaction (analog scale), and whether, if given it to do over, they would opt for surgery again. RESULTS: Of the original 100 patients, 40 were studied an average of 5 years after surgery: 26 completed laparoscopically and 14 with laparoscopic failure (13 conversions and 1 early reoperation). Patient characteristics in the two groups were similar, except that there were more older patients with more fixed intrathoracic hiatus hernias in the failure group. Among the parameters examined, no statistically significant differences could be detected between laparoscopic and converted patients. CONCLUSIONS: General and system-specific quality of life, digestive symptoms, need for medication, patient satisfaction, and willingness to have surgery over again are not altered by conversion or reoperation. Thus, surgeons who have adequate laparoscopic skills, experience with open fundoplication, and training in laparoscopic Nissen fundoplication should feel free to add it to their repertoires provided the likelihood of conversion and reoperation secondary to inexperience is understood by the patient.

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.
