Comparison of laparoscopic versus conventional open cryptorchidectomies on intraoperative and postoperative complications and duration of surgery, anesthesia, and hospital stay in horses
Bibliographic record
Abstract
Objective-To compare surgical preparation time, surgery and anesthesia times, hospitalization duration, and intra- and postoperative complications between laparoscopic and conventional open cryptorchidectomy in horses. Design-Retrospective cohort study. Animals-60 horses that underwent cryptorchidectomy. Procedures-Medical records were reviewed to identify horses that had undergone cryptorchidectomy from 1991 to 2012. Thirty horses that underwent laparoscopic cryptorchidectomy (case horses) were matched with 30 control horses that had undergone open cryptorchidectomy (ie, inguinal and parainguinal surgical approaches). Horses were matched according to history of previous surgery, testicle location, and type of closure following removal of an undescended unilateral testicle. Duration of surgery, surgical preparation and anesthesia times, hospitalization duration, and number of intra- and postoperative complications were compared between horses that underwent laparoscopic cryptorchidectomy versus open cryptorchidectomy. Comparisons were also made between horses in terms of whether there was a history of previous failed cryptorchidectomy or unknown location of testicle prior to surgery. Results-Horses that underwent laparoscopic cryptorchidectomy had significantly longer surgery and anesthesia times overall, compared with horses that underwent open cryptorchidectomy. No difference in surgery time was found between case and control horses that had a previous surgical attempt to remove an undescended testicle or in which the testicle location was unknown prior to surgery. Overall, horses undergoing laparoscopy had a nonsignificant increase in intraoperative complications, compared with control horses, and had significantly more postoperative complications. Conclusions and Clinical Relevance-Horses undergoing laparoscopic cryptorchidectomy had increased surgical preparation time, increased surgery and anesthesia times, and more postoperative complications, compared with horses undergoing open cryptorchictomy. Laparoscopy may be advantageous for a second attempt at cryptorchidectomy or if the testicle location is unknown prior to surgery.

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.
