Introducción: La colecistitis aguda (CA) es una de las urgencias digestivas más frecuentes. El tratamiento de elección es la colecistectomía laparoscópica (CL), que puede ser muy compleja en ciertos pacientes. Predecir preoperatoriamente una CL difícil es importante a nivel asistencial.

Introduction: Acute cholecystitis (AC) is one of the most frequent digestive emergencies. The treatment of choice is laparoscopic cholecystectomy (LC), which can be very complex in certain patients. Preoperatively predicting a difficult CL is essential at the healthcare level. There are several non-internationally accepted systems for determining CL difficulty. C-reactive protein (CRP) is an analytical variable systematically measured throughout AC. Objective: to determine if preoperative CRP measurement can determine the difficulty of LC in AC. Methods: Retrospective observational study. Study period: 2016-2018. Inclusion criteria: patients diagnosed with CA and treated by urgent LC in the first 72 hours. Exclusion criteria: previous admission for AC in the last six months, and <18 years. Difficulty was measured according to the scale of Ramírez et al. Operative CRP determination was performed upon admission We measured complications according to Clavien-Dindo. Results: We studied 209 patients diagnosed with AC and undergoing LC. Age: 63.32 years (range: 28-93, of which 111 (53.1%) are men. The mean Charlson index was 3.08 (range: 0-9), and the ASA distribution was 1 (31. 1%), ASA2 (41.1%), ASA3 (23.9%), and ASA 4 (3.8%). The mean evolution time from onset to diagnosis was 2.8 days (range: 1-30%). 134 (64.1%) were classified as TG18 Grade II, 59 (28.2%) Grade I, and 16 (7.7%) Grade III. The mean CRP in the emergency room was 12.89 mg/Dl (range: 0.03- 56.70) neutrophils: 11230.47, platelets 240458.85 and lymphocytes 1589.95 and neutrophil/lymphocyte ratio 135.03. The difficulty of LC, according to the Ramírez scale, was grade I in 79 patients (37. .8%), grade II in 89 (42.6%), grade III in 38 (18.2%), and 3 grade IV (1.4%). The average surgery time was 84 minutes (28-360). 13 (6.2%) required conversion to open surgery. Forty-six patients (22%) presented postoperative complications: 13 grade I, 8 II, 12 IIIA, 5 IIIB, 3 IV, and 5 V. The hospital readmission rate was 16.7%. A ROC curve was performed to establish the relationship between sensitivity and specificity of CRP in predicting difficult cholecystectomy. The area under the curve (AUC) was 0.625, statistically significant (p=0.013). With a precision of 52.63%, the optimal cut-off value for complex CL was 7.4 mg/dL. The sensitivity and specificity achieved by acquiring this cut-off point are 70.7% and 51.8%, respectively, with a positive predictive value of 25% and a negative predictive value of 87.1%. Conclusion: In our series, a CRP greater than 7.4 mg/dL presents a greater risk of difficult cholecystectomy. This simple data, performed regularly without increasing costs, can allow us to catalog cholecystectomies and distribute health resources more efficiently.
