Gasless laparoscopy versus conventional laparoscopy and laparotomy: A systematic review on the safety and efficiency
Bibliographic record
Abstract
Abstract Background Gasless laparoscopy (GL) emerged to overcome the clinical and financial challenges of pneumoperitoneum and is often seen as a viable option for use in resource‐limited settings as a means of saving costs and resources. This study aims to systematically review the evidence available on the safety and efficiency of GL compared with conventional laparoscopy (CL) and laparotomy. Methods Following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines, Medline, Embase, Web of Science and Cochrane databases were searched. Variables of interest were determined a priori and Covidence software was used to screen studies for inclusion without demographic preference. The quality of studies was assessed using the Cochrane Risk Assessment tool. Results Of the 1080 studies screened, a total of 43 studies were included. Laparoscopic cholecystectomy was by far the most studied intervention in randomised studies. In these, the mean setup time for gasless and CL was 13.14 (95% CI −0.16 to 26.44) and 12.8 (95% CI −10.86 to 36.47) minutes, respectively. The mean duration of surgery for gasless and CL was 89.39 (95% CI 77.44 to 101.34) and 72.59 (95% CI 63.44 to 81.74) minutes, respectively, and the mean length of stay was 4.25 (95% CI 2.02 to 6.48) and 4.04 (95% CI 1.72 to 6.36) days, respectively. Most reported complications were haemorrhage and infection with no assessable statistical difference. Conclusions Although GL seems to be a feasible approach for many general surgery interventions, the observed outcomes based on safety and efficiency are not sufficient to recommend GL as an alternative to CL or laparotomy. Larger randomised trials with a low risk of bias are warranted.

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.
