A Randomized Clinical Trial Comparing Laparoscopic and Vaginal Hysterectomy for Benign Disease: An Egyptian University Hospital Experience
Bibliographic record
Abstract
Objective: This research compared laparoscopic hysterectomy (LH) and vaginal hysterectomy (VH) for operative time, complications, postoperative pain, inflammatory response, hospital stay, and costs. Materials and Methods: A randomized controlled trial compared LH and VH for 80 patients equally allocated to undergo either for benign pathology (Canadian Task Force Classification I). Results: Mean operative time was significantly higher for LH (127.5 ± 25.9 minutes; 95% confidence interval [CI]: 119.2, 135.8) than for VH (104 ± 30.8 minutes; 95% CI: 94.2, 113.9); p = 0.0004. There was no significant difference in median blood loss (LH: 250 mL and VH: 235 mL); p = 0.7983). There was a strong positive correlation between operative time and estimated uterine weight, especially for VH. Adnexal surgery was performed as planned preoperatively in 62.5% of LHs versus 27.5% of VHs; p < 0.0035. Both groups were comparable regarding intra- and postoperative complications ( p = 1.0). Median postoperative pain intensity was lower in LH than in VH at 2 hours (51 versus 64.5; p = 0.0038), 6 hours (38.5 versus 46; p = 0.0009), and 24 hours (24.5 versus 36.5; p < 0.0001). Inflammatory response did not differ between the groups, neither as postoperative fever (7.5% of LH versus 2.5% of VH; p = 0.6153) nor as postoperative C-reactive protein rise (median: 57.4 mg/L for LH; 41.6 mg/L for VH; p = 0.1489). There was no difference in hospital stay (LH median: 35.5 hours; VH median: 30 hours; p = 0.6991). Costs for LH were higher (LH median: 5525 Egyptian pounds (EGPs), 335 US dollars (USD); VH median: 3400 EGPs, 207 USD; p < 0.0001). Conclusions: LH has longer operative time, yet better postoperative pain profile, than VH. However, cost considerations make LH fall behind VH as a primary choice for benign hysterectomy, especially in low-resource settings. (J GYNECOL SURG 38:400)

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.
