Key result
A preoperative platelet-to-lymphocyte ratio ≥190.56 predicted conversion from laparoscopic to open appendectomy with 76.9% sensitivity and 84% specificity (AUC 0.853; 95% CI 0.728-0.928; P<0.001).

Preoperative PLR is a useful predictive biomarker for the need to convert from laparoscopic to open appendectomy in patients with acute appendicitis.
Elevated preoperative PLR was associated with conversion risk; leaves open whether it should inform surgical decisions pending prospective studies.

Bozan et al. (2021) conducted a cohort in Acute appendicitis (n=117). Preoperative Platelet-to-Lymphocyte Ratio (PLR) vs. Lower PLR was evaluated on Conversion from laparoscopic to open surgery (AUC 0.853, 95% CI 0.728-0.928, p=<0.001). A preoperative platelet-to-lymphocyte ratio ≥190.56 predicted conversion from laparoscopic to open appendectomy with 76.9% sensitivity and 84% specificity (AUC 0.853; 95% CI 0.728-0.928; P<0.001).
