Acute Cholangitis After Bilioenteric Anastomosis for Bile Duct Injuries.

BACKGROUND/PURPOSE: The study aims to describe the clinical features, microbiology, and associated factors of acute cholangitis (AC) after bilioenteric anastomosis (BEA) for biliary duct injury (BDI). Additionally, we assessed the performance of the Tokyo Guidelines 2013 (TG13) recommendations in these patients. METHODS: We conducted a case-control study of 524 adults with a history of BEA for BDI from January 2000 to January 2014. A propensity score adjustment was performed for the analysis of the independent role of the main factors identified during the univariate logistic regression procedure. RESULTS: We identified 117 episodes of AC in 70 patients; 51.3% were definitive AC according to the TG13 diagnostic criteria, and 39.3% did not fulfill the imaging criteria of AC. A history of post-operative biliary complications (OR 2.55, 95% CI 1.38-4.70) and the bile duct confluence preservation (OR 0.46, 95% CI 0.24-0.87) were associated with AC. Eighty-nine percent of the microorganisms were Enterobacteriaceae; of them, 28% were extended spectrum ß-lactamase (ESBL) producers. CONCLUSIONS: AC is a common complication after BEA and must be suspected even in the absence of imaging findings, particulary in patients with a history of post-operative biliary complications, and/or without bile duct confluence preserved. An empirical treatment for ESBL-producing Enterobacteriaceae may be appropriate in patients living in countries with a high rate of bacterial drug resistance.

Reconstrucción de la vía biliar junto al tratamiento adyuvante con ácidoursodesoxicólico en lesiones/estenosisiatrogénicas posterior a colecistectomías. Resultados iniciales / Biliary reconstruction surgery follow by adju-vant therapy with ursodesoxicolcy acid in injury/stenosis after cholecistectomy. Prelimi-nary results

El tratamiento de la estenosis biliar benigna (EBB) constituye unreto médico, más del 70% de los casos son resueltos endoscópica-mente, reservando los más complejos para el abordaje quirúrgico,con una tasa éxito que ronda del 92 % al 60%. Una técnica qui-rúrgica impecable junto a factores favorables del paciente es la prin-cipal garantía de éxito. Objetivo: Mantener un adecuado flujo biliar es uno de los factoresprincipales para evitar inflamación y éstasis biliar, por lo que hemosemprendido el siguiente protocolo de estudio con terapia adyuvantecon ácido ursodesoxicólico posterior a la reconstrucción biliar.Métodos: Ensayo clínico prospectivo no aleatorizado, donde seincluyen pacientes con estenosis biliar benigna desde agosto 2012hasta agosto 2014.Resultados:Se han incluido 13 pacientes con preponderancia delsexo femenino con un 77 %, las estenosis tipo Bismuth 1 y 2 ocu-paron un 23 %, mientras que para Bismuth 4 y 5 un 15,38 % res-pectivamente, las EBB producto en anastomosis biliodigestiva ocu-rrió en un 23 %. El seguimiento promedio fue de 13,3 meses.Posterior al tratamiento, sólo 1 paciente experimentó colangitis enausencia de estenosis. Hasta la fecha de seguimiento ninguno hapresentado re-estenosis.Conclusión: Una técnica quirúrgica impecable junto al tratamientoadyuvante con ácido ursodesoxicólico pareciera ofrecer buenosresultados a fin de evitar la re-estenosis y la colangitis, por lo que suaplicación debe ser estudiada por periodos de tiempo prolongados(AU)

The benign biliary stenosis is a medical challenge; more than 70%of them are resulted endoscopically, leaving the most difficult casesfor surgical treatment, which can reach a success between 92% and60%. Meticulous surgical techniques with better patient prognosticfactors are guarantee of success. Objective:The adequate biliary flow is related with less inflationand less biliary stasis, that's why we decide to use ursodesoxicolicacid as an adjuvant treatment after biliary reconstruction surgery.Methods: Non randomized clinical trial, including patients betweenAugust 2012 to August 2014 with benign biliary stenosis.Results:Were included 13 patients, most of them women 77%.Type 1 and 2 Bismuth 23%, Bismuth 4 -5 15,38 % respectively, and23 % for stenosis of the biliodigestive anastomosis. The medianfollow up was 13,3 months. After surgical reconstruction there wereonly 1 patient who revealed cholangitis, and no restenosis in thefollow up period. Conclusion:A meticulous surgical technique and adjuvant treat-ment with ursobilanic acid seem to show good results avoiding re-stenosis and cholangitis, prolong study period is required(AU)
