A Simple Technique for Laparoscopic Vertical Banded Gastroplasty – The JOVO Procedure
Bibliographic record
Abstract
A simple technique for laparoscopic vertical banded gastroplasty is described. With the surgeon to the patient's left, four trochars are placed as cephalad as possible. Short gastric vessels are divided and the posterior wall of the stomach mobilized. The ETS-Flex with Articulating Head (Ethicon Endosurgery Inc.) is used to divide the stomach close to a 42-french bougie against the lesser curvature. An additional stapler bite abuts directly against a 28-french bougie to obtain correct stoma size. A ribbon of Prolene mesh is pulled through a tunnel behind the stomach at the apex of the divided gastroplasty and sutured around the distal end of the gastroplasty. To date we have used this method successfully in 5 patients with 1-11 months of follow-up. Although we lack a sufficient number of patients or follow-up for definitive conclusions, we believe this technique will produce good results, as it reproduces exactly that used successfully in open surgery and our early results parallel those following open surgery.

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.
