Open or minimally invasive esophagectomy: are the outcomes different?
Bibliographic record
Abstract
PURPOSE OF REVIEW: Since the beginning of the 1990s, the use of minimally invasive esophagectomy instead of the open technique has increased. Should this type of approach change the way we manage anesthesia for a patient undergoing esophagectomy for cancer? RECENT FINDINGS: Because valid direct comparisons with open surgery are lacking, one cannot make definitive statements regarding the potential benefits of minimally invasive surgery. Rough comparisons with recent reports on open surgery suggest that reduced mortality, respiratory complications and blood loss, plus a more rapid return to a good quality of life are areas in which minimally invasive surgery might prove superior. Leak rates were similar to those reported with open procedures. Surprisingly, length of hospital stay and overall morbidity are similar with both techniques. Reported operating times appear longer than one might expect for open operations, which mirrors the experience of laparoscopic procedures in other areas. SUMMARY: The implantation of minimally invasive esophagectomy seems inevitable in spite of the absence of randomized, controlled trials. The use of the prone position with one lung ventilation during minimally invasive esophagectomy seems positive. Protective ventilation during one lung ventilation may help to prevent pulmonary complications. Finally, the well accepted use of thoracic epidural anesthesia now has a new positive role following esophagectomy, improving the perfusion at the anastomotic level.

How this classification was reachedexpand
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.
