Laparoscopy versus open surgery for adnexal masses in pregnancy: a meta-analytic review
Bibliographic record
Abstract
PURPOSE: The objective of this meta-analysis is to investigate and compare the pregnancy outcomes of laparoscopy and open surgery in the treatment of ovarian tumors during pregnancy. METHODS: Search was conducted using MEDLINE, EMBASE, and Cochrane Databases from January 1990 to November 2018. A broad search strategy was used to identify studies comparing laparoscopy and open surgery in pregnancy. Inclusion criteria included comparative studies with the quantitative outcome data on gravida. Two authors independently reviewed and assessed for the quality of included studies according to the Newcastle-Ottawa Scale. Data were extracted for fetal loss, preterm delivery, duration of surgery, blood loss and length of hospital stay. RESULTS: Nine retrospective trials were identified involving 985 patients. No statistical significance was found in fetal loss between laparoscopy and open surgery (P value = 0.334). The pooled estimate for preterm labor statistically significantly decreased for laparoscopy group (P value = 0.014). Reduced operative blood loss was found in laparoscopy group by 83.81 ml (P value = 0.015). Duration of operation may be longer in the laparoscopy group, but without statistical significance (P value = 0.346). Length of hospital stay was shorter in the laparoscopy group with reduction of 1.95 days (P value < 0.001). CONCLUSIONS: The available low-grade evidence suggests that laparoscopic surgery might be a feasible alternative for pregnant women with adnexal masses.

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.
