Score preoperatorio para la predicción de colecistectomía difícil / Realization of a preoperative score for the prediction of difficult cholecystectomy

Introducción: La colecistectomía es una de las intervenciones quirúrgicas más frecuentes en la práctica médica diaria, la misma no está exenta de complicaciones, especialmente en algunos pacientes con mayor predisposición. Objetivo: Diseñar un score de puntuación preoperatoria para la predicción de la colecistectomía difícil en el área de emergencia y consulta del servicio de Cirugía General del Hospital General del Este "Dr. Domingo Luciani" Caracas - Venezzuela. Métodos: Estudio descriptivo, de diseño longitudinal. Realizado en el período agosto 2018 - agosto 2019. Contó con una muestra de 99 pacientes a los cuales se les aplicó un score predictivo preoperatorio donde se precisaron datos sobre el examen físico, antecedentes personales y quirúrgicos, enfermedades asociadas, exámenes de laboratorio y hallazgos en ultrasonido abdominal, previa firma del consentimiento informado se procedió a evaluar y hacer revisión de los paraclínicos de cada paciente, para luego ser reportado en el score. Resultados: Se registró una edad promedio muestral de 48,25 años ± 1,58, con una mediana de 47 años, el sexo femenino fue el más frecuente (60,61% = 60 casos), de aquellos pacientes clasificados con colecistectomía difícil según el score predictivo experimental predominaron aquellos con presencia de vesícula palpable y antecedentes de colecistitis, el hallazgo de laboratorio más importante fue la leucocitosis (≥ 15x106). Conclusión: El uso del score predictivo planteado permite predecir el riesgo de complicación en una colecistectomía difícil usando como base, las características clínicas y paraclínicas del paciente al momento de su evaluación preoperatoria(AU)

Introduction: Cholecystectomy is one of the most frequent surgical interventions in daily medical practice, it is not without complications, especially in some patients with greater predisposition.. Objective: Design a preoperative score for the prediction of difficult cholecystectomy in the emergency and medical consultation area of the General Surgery service of the Eastern General Hospital "Dr. Domingo Luciani". Methods: A descriptive study, longitudinal design. Performed in the period August 2018-August 2019. It had a sample of 99 patients who were given a preoperative predictive score requiring data on the physical examination, personal and surgical history, associated diseases, laboratory test and findings in abdominal ultrasound, upon signature of the informed consent was proceeded to evaluate and make revision of the paraclinical of each patient, and then be reported in the score. Results: An average sample age of 48.25 years ± 1.58, with a median age of 47 years, the female sex was the most common (60.61%=60 cases), in those patients classified with difficult cholecystectomy, according to the experimental predictive score, predominated those with the presence of palpable vesicle and history of cholecystitis, the most important laboratory finding was leukocytosis (≥ 15x106). Conclusion: The use of the predicted score allows to precise the risk of complication in a difficult cholecystectomy using the clinical and paraclinical characteristics of the patient at the time of their preoperative evaluation(AU)

Papel de la proteína C reactiva y la velocidad de sedimentación globular en la predicción de colecistectomía laparoscópica dificultosa: su aplicación en un programa de residencia universitario / Role of C-reactive protein and erythrocyte sedimentation rate to predict difficult laproscopic cholecystectomy in a university residency program

Antecedentes: la colecistectomía laparoscópica es uno de los procedimientos quirúrgicos más frecuentemente realizados. Las diferencias en la anatomía y en el grado de inflamación vesicular suelen causar dificultades técnicas intraoperatorias. Objetivo: determinar el valor de la proteína C reactiva (PCR) y la velocidad de sedimentación globular (VSG) como predictores de colecistectomía dificultosa y evaluar su aplicación en la planificación prequirúrgica de un programa de residencia universitario. Material y métodos: se confeccionó un estudio retrospectivo, analítico, en un hospital universitario de tercer nivel. Se incluyeron 104 pacientes adultos operados de colecistectomía laparoscópica por litiasis vesicular sintomática entre enero y julio de 2019. Se categorizó a los pacientes en un grupo de colecistectomías dificultosas y otro de colecistectomías no dificultosas. Resultados: se obtuvieron diferencias estadísticamente significativas al comparar los valores de VSG y PCR de ambos grupos (p < 0,001). La sensibilidad de la VSG fue del 100%, la especificidad del 45%, el VPP del 40% y el VPN de 100%. La sensibilidad de la PCR fue del 87,5%, la especificidad del 86,3%, el VPP del 70% y el VPN de 95%. Ambos parámetros se vieron elevados en 14 de 16 colecistectomías dificultosas y en 2 de 44 colecistectomías no dificultosas. La sensibilidad para ambos parámetros elevados fue del 87,5%, la especificidad del 95%, el VPP del 87,5% y el VPN de 95%. Conclusión: la VSG y la PCR han demostrado ser un método fiable en la predicción de colecistectomías dificultosas por litiasis vesicular sintomática. Esto podría ser aplicado en la programación de cirugías dentro de un programa de residencia universitario.

Background: laparoscopic cholecystectomy is one of the most common procedures performed in general surgery. The anatomical differences of the gallbladder and the presence of factors related to inflammation can cause technical issues during surgery. Objective: the aim of the present study was to determine the value of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) as predictors of difficult cholecystectomy and to evaluate their application during presurgical planning within a university residency program. Material and methods: we conducted a retrospective and analytical study in a tertiary university hospital. A total of 104 adult patients undergoing laparoscopic cholecystectomy due to symptomatic cholelithiasis between January and July 2019 were included. The patients were categorized into two groups: difficult cholecystectomy and non-difficult cholecystectomy. Results: there were statistically significant differences in ESR and CRP values between both groups (p < 0.001). Sensitivity of ESR was 100%, specificity was 45%, with a PPV of 40% and NPV of 100%. Sensitivity of CRP was 87.5%, specificity was 86.3%, with a PPV of 70% and NPV of 95%. Both parameters were elevated in 14 of 16 difficult cholecystectomies and in 2 of 44 non-difficult cholecystectomies. Sensitivity of CRP was 87.5%, specificity was 86.3%, with a PPV of 70% and NPV of 95%. Conclusion: measuring ESR and CRP has proved to be a reliable method to predict difficult cholecystectomies due to symptomatic cholelithiasis. This could be applied for surgical planning within a university residency program.

Prediction of difficult cholecystectomy, a study of 100 cases

Background: Cholelithiasis is a common problem in day to day surgical practice, which has a prevalence of 10-15%. The prevalence is more here in this part of the country as this is a pocket of sickle cell disease region. Laparoscopic cholecystectomy is the gold standard procedure for gall stone diseases. Out of many complications one of the most important complications of laparoscopic cholecystectomy is bile duct injury particularly in difficult cases.  Difficulties arise during creation of pneumoperitonium, releasing adhesion, identifying anatomy, anatomical variations and during extraction of gall bladder.Methods: A prospective study was carried out at VSS institute of Medical Science and Research, Burla, Sambalpur, a tertiary referral centre and a teaching hospital in the western Odisha. One hundred patients with symptomatic cholelithiasis were taken up for the study after due clearance from the institutional ethical committee. They were evaluated for risk factors such as-age of the patient, sex of the patient, previous abdominal surgery, number of previous attacks, total WBC count, gall bladder wall thickness and pericholecystic collection on ultrasonography.Results: Previous abdominal surgery, duration since acute attack, number of previous attacks, ultrasonography findings of increased wall thickness, stone impaction at neck and pericholecystic collection, increased total WBC count are associated with difficult laparoscopic cholecystectomy.Conclusions: The predictors for difficult cholecystectomy will make the surgeon extra cautious during the procedure so as to minimize the complications.
