C-reactive protein as a predicting factor for difficult laparoscopic cholecystectomy or its conversion to open cholecystectomy in acute calculous cholecystitis: an observational study.
Observational study in BMC surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionAcute calculous cholecystitis (ACC) is a common surgical emergency often requiring laparoscopic cholecystectomy (LC), though some cases necessitate conversion to open cholecystectomy (OC). Predicting difficult LC or conversion is crucial for operative planning. This study evaluates the role of C-reactive protein (CRP) as a predictor of surgical complexity in ACC.
methodsA prospective observational study was conducted at Shree Birendra Hospital, Kathmandu, from April 2024 to March 2025, including 108 patients undergoing emergency LC for ACC. Patients with conditions confounding CRP levels were excluded. Preoperative CRP levels were measured, and operative time was recorded. LC lasting more than 60 min was defined as difficult. Statistical analysis was performed using SPSS 26.0.
resultsAmong 108 patients (mean age 49.8 years, male to female ratio 1:3.5), 71 underwent simple LC, 28 difficult LC, and 9 were converted to OC. Mean CRP levels were 18.2 mg/L in simple, 36 mg/L in difficult, and 50.1 mg/L in converted cases (p = 0.002). A significant association was found between elevated CRP and surgical complexity (p < 0.001). Duration of surgery and hospital stay increased with complexity (p < 0.001), while age and gender showed no significant association.
conclusionsElevated preoperative CRP levels are significantly associated with increased surgical complexity and likelihood of conversion in ACC. CRP can serve as a valuable tool for anticipating technical challenges and optimizing resource, especially in resource limited setting.
