RESUMEN
INTRODUCTION: This study aimed to evaluate the use of laparoscopic cholecystectomy (LC) operative time (CholeS score) and conversion to an open procedure (CLOC score) outside their validation dataset in Mexican population. METHODS: Patients >18 years who underwent elective LC were analyzed in a single-center retrospective chart review study. Association between scores (CholeS and CLOC) with operative time and conversion to open procedures was assessed with Spearman correlation. The predictive accuracy of the CholeS score and CLOC score was evaluated by receiver operator characteristic. RESULTS: 200 patients were included in the study (33 excluded for emergency case or missing data). Spearman coefficient correlations between CholeS or CLOC score and operative time were 0.456 (p < 0.0001) and 0.356 (p < 0.0001), respectively. Area under the curve (AUC) for operative prediction time (>90 min) by CholeS score was 0.786 with a 3.5-point cutoff (80% sensitivity and 63.2% specificity). AUC for open conversion (CLOC score) was 0.78 with a 5-point cutoff (60% sensitivity and 91% specificity). The CLOC score had a 0.740 AUC (64% sensitivity and 72.8% specificity) for operative time >90 min. CONCLUSIONS: The CholeS and the CLOC scores predicted LC long operative time and risk for conversion to an open procedure, respectively, outside their original validation set.

BACKGROUND: Mexican health system structure allows us to study the differences in bile duct injury (BDI) management. The study aimed to assess the differences in patients with complex BDI in 2 different public sector institutions using a new proposed standard terminology. METHODS: Retrospective review (2008-2019) in 2 public institutions (IMSS/SESVER). Bismuth-Strasberg E injuries with hepaticojejunostomy were included. Data are presented in a tabular reporting system. The outcomes were percent of patients attaining primary patency, loss of primary patency, and actuarial primary patency rate. RESULTS: Seventy-eight patients (IMSS: n = 37; SESVER: n = 41) without differences in demographic and preoperative assessment were studied. BDI occurred mostly in outside hospitals. Open cholecystectomy was the most common index operation in SESVER (73%, p = 0.02). IMSS had more surgeries (p = 0.007) and repair attempts (p = 0.06) prior to referral. Magnetic resonance cholangiopancreatography was more commonly used in IMSS patients. Biliary stents (45%) and cholangitis (29%) were more common in IMSS (p < 0.05). IMSS patients had longer follow-up than SESVER (p < 0.05). No differences in primary patency rates (IMSS: 89%, SESVER: 97%) and actuarial patency rates were noted. DISCUSSION: Despite differences in referral, preoperative, and operative events, good BDI repair outcomes can be achieved. Longer follow-up is needed to monitor these outcomes.

Background: The Estimated Post Transplant Survival (EPTS) score is calculated based on age, the presence of diabetes mellitus, years on dialysis, and prior organ transplant. The EPTS score has been validated in other countries. Objective: To apply and assess the EPTS score in our population of deceased-donor kidney transplants. Materials and methods: Retrospective study of adult deceased-donor kidney transplants from January, 2003, to December, 2016. For the statistical analysis it was used Spearman's correlation, receiver-operator curves (ROC) and Kaplan-Meier curves. A p value < 0.05 was considered statistically significant. Results: 176 adult deceased-donor kidney transplants were included. Medium age was 34.7 ± 11 years; 53.4% were men, 4% diabetics; mean dialysis time was 5.5 ± 3.9 years and 4% had a prior organ transplant. The medium of EPTS score was 16.3 ± 18.7 (1 94). Spearman's correlation was −0.394 (p = 0.0001). C value (ROC) was 0.64 ± 0.6 (95% CI, 0.52-0.75) (p = 0.011). Medium survival calculated with Kaplan-Meier in patients with an EPTS score < 20, was 10.2 ± 0.3 years (95% CI, 9.5-10.9) versus patients with EPTS score > 20: 7.03 ± 0.9 years (95% CI, 5.1-8.9) (p = 0.001). Each 20% increase of EPTS, patient survival time diminished (p = 0.0001). Conclusions: The EPTS score is a useful tool for establishing survival in adult Mexican recipients of deceased-donor kidney transplants.
Introducción: la escala de sobrevida estimada postrasplante (EPTS) se calcula a partir de la edad, la presencia de diabetes mellitus, el tiempo en diálisis y el trasplante previo. La EPTS ha sido previamente validada en otros sitios. Objetivo: aplicar y evaluar la escala EPTS en nuestra población de trasplantes de donante fallecido. Material y métodos: estudio retrospectivo de trasplantes renales de donantes adultos fallecidos, llevados a cabo entre enero de 2003 y diciembre de 2016. Para el análisis estadístico se utilizaron correlación de Spearman, curvas de ROC y Kaplan-Meier y se consideró significativa una p < 0.05. Resultados: se incluyeron 176 trasplantes de donantes adultos fallecidos; 53.4% fueron hombres, 4% diabéticos; la edad media fue de 34.7 ± 11 años; el tiempo medio en diálisis fue de 5.5 ± 3.9 años y 4% tuvo trasplante previo. La media de la escala EPTS fue de 16.3 ± 18.7 (rango 1-94). La correlación Spearman fue −0.394 (p = 0.0001). El valor C de la curva ROC fue de 0.64 ± 0.6 (IC 95% 0.52-0.75) (p = 0.011). La supervivencia media calculada con Kaplan-Meier en pacientes con EPTS < 20 fue 10.2 ± 0.3 años (IC 95% 9.5-10.9) frente a los pacientes con EPTS > 20: 7.03 ± 0.9 años (IC 95% 5.1-8.9) (p = 0.001). Por cada 20% que se incrementó la EPTS, la supervivencia del paciente fue menor (p = 0.0001). Conclusiones: la escala EPTS es una buena herramienta para establecer la supervivencia en pacientes adultos mexicanos receptores de trasplante renal de donante fallecido.
