Sleep deprivation among surgical residents: Does it affect performance while practising a laparoscopic intestinal anastomosis?

INTRODUCTION: To assess the impact of fatigue due to incorrect night rest in the performance of a laparoscopic manual anastomosis. METHODS: A prospective study evaluating the results from the realization of a manual endotrainer entero-enteral anastomosis performed by residents in terms of fatigue caused by inadequate nightly rest. Two groups were established; the FATIGUE group (F): anastomosis performed by residents coming off shift who slept less than seven hours and the REST group(R), being those who slept at home for more than 7 h. The time taken, length of the anastomosis and quality of such were compared based on 4 parameters: Air leak test, correct tension on the suture line, accurate opposition of the edges and optimal distance between stitches. RESULTS: 402 anastomoses were studied (211 rest group, 191 fatigue group). In the fatigue group leaks were detected in 33.5% anastomoses, as opposed to 19.4% in the rest group (P < .01). El rest group performed the anastomosis in 56.75 min and the fatigue group in 61,49 min (P = .006). There were no significant differences in the others parameters. CONCLUSIONS: Fatigue increases the risk of leakage and the time to do the exercise.

Predicting factors for the diagnosis of gangrene acute cholecystitis.

Background: Gangrenous cholecystitis (GC) must be promptly treated for its high morbimortality. The object of our study is to identify clinical, laboratory or ultrasound factors that might us diagnose GC. Method: A Retrospective cohort study is devised including all patients admitted to Hospital de Laredo (Cantabria, Spain) between 2015 and 2017 with the diagnose of acute cholecystitis and having been operated. Patients were classified in two groups according to pathology: GC and non-GC. We compared their demographics characteristics, comorbidities, laboratory parameters and ultrasound findings. Results: A total of 115 patients were operated, of whom 32 had CG and 83 CNG. Neutrophil-to-lymphocyte ratio and C-reactive protein (CRP) showed significantly increased levels in GC group (p = 0.042) and CRP (p < 0.0001). To CRP showed an area under the ROC curve of 0.872 (95% confidence interval: 0.797-0.946). Acalculous cholecystitis was significantly associated to GC (24.1 vs. 7%; p < 0.005). In the multivariate analysis only the CPR showed as a predictive factor. A cutting point of CRP at 15.25 mg/dl, that had high sensibility (90.6%) and high negative predictive value (95%). Conclusion: CRP helped identify patients with CG to indicate early surgical intervention.

Antecedentes: La colecistitis aguda gangrenosa (CG) debe tratarse precozmente por su alto riesgo de morbimortalidad. Objetivo: Identificar factores clínicos, analíticos o ecográficos que permitan diagnosticar CG preoperatoriamente. Método: Estudio de cohorte retrospectiva en el Hospital de Laredo (Cantabria, España), entre 2015 y 2017, de pacientes con diagnóstico de colecistitis aguda que hayan sido intervenidos. Se clasificó a los pacientes en dos grupos según el diagnóstico anatomopatológico: CG y colecistitis no gangrenosa (CNG). Se compararon las características demográficas, la comorbilidad, los datos analíticos y los datos ecográficos. Resultados: Fueron operados 115 pacientes, de los cuales 32 tenían CG y 83 tenían CNG. Los pacientes con CG muestran unos valores más altos de índice de neutrófilos/linfocitos (p = 0.042) y de proteína C reactiva (PCR) (p < 0.0001). La colecistitis alitiásica se asoció con mas frecuencia a la CG (24.1 vs. 7.0%; p < 0.005). En el estudio multivariable, solo la PCR se muestra significativa. La PCR mostró un área bajo la curva ROC de 0.872, (intervalo de confianza del 95%: 0.797-0.946). Un punto de corte de PCR de 15.25 mg/dl tuvo una alta sensibilidad (90.6%) y un alto valor predictivo negativo (95%). Conclusión: La PCR ayuda a identificar a los pacientes con CG para indicar una intervención quirúrgica precoz.
