Controversias en cirugía: colelitiasis y coledocolitiasis ¿Exploración de vías biliares laparoscópica más colecistectomía laparoscópica (cirugía en un paso) o CPRE y colecistectomía laparoscópica (cirugía en dos pasos)? / Controversies in surgery: Cholelithiasis and choledocholithiasis - Laparoscopic bile duct exploration plus laparoscopic cholecystectomy (one-step surgery) or ERCP and laparoscopic cholecystectomy(two-step surgery)?

Introducción. La colelitiasis tiene una prevalencia del 15 % y el 21 % tendrá coledocolitiasis al momento de la colecistectomía, con 50 % de probabilidad de presentar complicaciones asociadas. Desde el advenimiento de la colecistectomía laparoscópica, el abordaje de la coledocolitiasis ha sido endoscópico, usualmente en un tiempo diferente al vesicular, sin embargo, los avances en laparoscopia han permitido explorar la vía biliar común por la misma vía, pudiendo realizar ambos procedimientos en el mismo tiempo de forma segura. Métodos. Se realizó una búsqueda de la literatura existente con relación al enfoque para el manejo de la colecisto-coledocolitasis en un paso comparado con dos pasos. Resultados. Existe evidencia que demuestra mayor efectividad del abordaje en dos pasos, con CPRE y posterior colecistectomía laparoscópica, sobre el abordaje en un paso, especialmente en la tasa de fuga biliar y de cálculos retenidos. El enfoque en un paso con exploración de vías biliares y colecistectomía laparoscópica en el mismo tiempo es seguro, con alta tasa de éxito, baja incidencia de complicaciones, menor estancia hospitalaria y costos. Conclusión. El abordaje laparoscópico en un solo paso es un procedimiento seguro y eficaz para el manejo de la colecisto-coledocolitiasis, con el beneficio de estancia hospitalaria menor, sin embargo, se requieren habilidades técnicas avanzadas en cirugía laparoscópica. En nuestro medio ya existe una infraestructura para el manejo híbrido con CPRE y colecistectomía laparoscópica, pudiéndose realizar ambos en el mismo tiempo, para reducir estancia y costos.

Introduction. Cholelithiasis has a prevalence of 15%, and 21% will have choledocholithiasis at the time of cholecystectomy, with a 50% probability of presenting associated complications. Since the advent of laparoscopic cholecystectomy, the approach to choledocholithiasis has been endoscopic, normative at a different time than the gallbladder; however, advances in laparoscopy have made it possible to explore the common bile duct by the same route, being able to perform both procedures in a single time safely. Methods. A search of the existing literature was performed regarding the one-step approach compared to the two-step approach for the management of cholelithiasis and choledocholithiasis. Results. There is evidence that demonstrates greater effectiveness of the two-step approach with ERCP and subsequent laparoscopic cholecystectomy over the one-step approach, especially in the rate of bile leak and the incidence of retained stones. The one-step approach with bile duct exploration and laparoscopic cholecystectomy at the same time is safe, with a high success rate, low incidence of complications, shorter hospital stay, and lower costs. Conclusion. The one-step laparoscopic approach is a safe and effective procedure for the management cholelithiasis and concomitant choledocholithiasis, with the benefit of a shorter hospital stay; however, advanced technical skills in laparoscopic surgery are required. In our environment there is already an infrastructure for hybrid management with ERCP and laparoscopic cholecystectomy, both of which can be performed at the same time to reduce hospital stay and costs.

Comparative study of diagnostic accuracy of magnetic resonance cholangiopancreatography (MRCP) with ultrasonography in choledocolithiasis with post endoscopic retrograde cholangio-pancreatography (ERCP) correlation

Background: Choledocolithiasis may be classified into primary and secondary forms. Primary choledocolithiasis denotes de novo formation of stones, often made of calcium bilirubinate within the ducts. Materials and Methods: The present prospective comparative study was conducted in the Department of Radio Diagnosis and Imaging, SMHS hospital, Government medical college srinagar. Patients admitted or attending OPD in SMHS hospital with suspected obstructive jaundice or who were known case of obstructive jaundice were included in the study. The study was performed on all patients after written informed consent was acquired from them. The study was carried out over a period of 24 months from August 2014 to July 2016. Results: Total 70 patients were selected for this comparative study after taking informed consent. Among 70 patients 50 patients were found to have choledocolithiasis. Rest 20 patients were found to Khan NA, Dar SA, Khan S, Yassar S. Comparative study of diagnostic accuracy of magnetic resonance cholangiopancreatography (MRCP) with ultrasonography in choledocolithiasis with post endoscopic retrograde cholangiopancreatography (ERCP) correlation. IAIM, 2017; 4(2): 35-41. Page 36 have obstructive jaundice due to causes other than choledocolithiasis. Out of 70 patients 40 (57%) patients were female and 30 (43%) patients were male. Conclusion: USG is inexpensive, non-invasive modality for choledocolithiasis, however has low sensitivity for detecting distal CBD calculi.

Bilioma espontâneo: relato de caso e revisão da literatura / Spontaneous biloma: a case report and literature review

Bilioma é qualquer coleção de bile fora das vias biliares. Geralmente, resulta de complicações cirúrgicas e trauma abdominal. A ocorrência espontânea é rara, ocasionalmente associada a coledocolitíase. Relata-se um caso de bilioma espontâneo, cujo diagnóstico foi confirmado radiologicamente. À laparotomia, observou-se bilioma retroperitoneal. A colangiografia transoperatória não evidenciou fístula. Após drenagem, o paciente teve boa evolução e alta hospitalar.

Biloma is defined as any collection of bile outside the biliary tree, usually resulting from surgery complications and abdominal trauma. Spontaneous occurrence of bilomas is rare, occasionally associated with choledocolithiasis. The present report describes a case of spontaneous biloma, whose diagnosis was radiologically confirmed. At laparotomy, the presence of a retroperitoneal biloma was observed. Intraoperative cholangiography has not demonstrated the presence of fistula. After drainage, the patient progressed well and was discharged.

Avaliação da positividade da colangiografia peroperatória em pacientes submetidos à colecistectomia laparoscópica eletiva / Assessment of positive perioperative cholangiography in patients undergoing elective laparoscopic cholecystectomy

OBJETIVO: A colecistectomia laparoscópica é o tratamento de escolha para pacientes com colecistopatia calculosa, embora o manejo da coledocolitíase associada ainda permaneça assunto controverso. O presente estudo baseou-se na análise prospectiva de pacientes submetidos à colecistectomia eletiva com colangiografia peroperatória, pretendendo assim avaliar a positividade do exame contrastado das vias biliares em pacientes com colelitíase sem indicação para colangiografia. MÉTODOS: Foram incluídos, no estudo, 100 pacientes cujos parâmetros clínicos, laboratoriais e de imagem feitos até no máximo 10 dias antes da colecistectomia não apresentaram qualquer alteração no pré-operatório e, portanto, considerados pacientes insuspeitáveis para coledocolitíase. As colangiografias foram analisadas e examinadas pela equipe cirúrgica, pelo radiologista e pelos autores deste estudo. Os laudos foram comparados e correlacionados com achados clínicos e laboratoriais prévios dos pacientes. RESULTADOS: A incidência de coledocolitíase insuspeitável no pré-operatório foi de apenas um único caso entre 100 pacientes sem indicação para o exame (1% de positividade). CONCLUSÃO: Com base neste material, pode-se concluir que o emprego da colangiografia seletiva é segura e deve ser empregada no tratamento da colecistite calculosa.

OBJECTIVE: To evaluate the positivity of cholangiography in patients without formal indication of this exam undergoing elective cholecystectomy. METHODS: We included, in the study, 100 patients whose clinical, laboratory and imaging not older than 10 days before the operation showed no change and therefore kept us unsuspicious of choledocholithiasis. The cholangiographies were analyzed and examined by the surgical team, the radiologist and the authors. The reports were compared and correlated with patients' previous clinical and laboratory findings. RESULTS: The incidence of preoperatively unsuspected choledocholithiasis was only one case (1%). CONCLUSION: The use of selective cholangiography is safe and should be used in the treatment of calculous cholecystitis.

Evaluación del manejo interdisciplinario de una serie de 53 pacientes con hepatolitiasis / Evaluation of interdisciplinary care of a series of 53 patients with hepatholithiasis

Objetivos: Evaluar, en una serie de enfermos con hepatolitiasis, el resultado del manejo interdisciplinario. Pacientes y métodos: Durante 8 años se valoraron, en un estudio retrospectivo, 53 pacientes con diagnóstico de hepatolitiasis. Resultados: Se estudiaron 23 hombres (43%) y 30 mujeres con una edad promedio de 50 ± 15 años (25 a 83 años). Predominó el dolor (94%), seguido de ictericia (68%) y fiebre (57%). Según la clasificación de Tsunoda, 6 pacientes eran Tsunoda I, 12 Tsunoda II, 4 Tsunoda III y 5 Tsunoda IV. El compromiso más frecuente fue del lóbulo izquierdo (36%) o bilateral (34%). La colangiografía endoscópica tuvo éxito en el 64% y solo se manejaron 4 pacientes por la vía transparietohepática (2 éxitos). Se operaron 35 pacientes (66%) y lo más frecuente fue la hepatectomía izquierda en 40% (7 con asa subcutánea) seguida por hepaticoyeyunostomía con asa subcutánea (26%). Se realizaron cuatro trasplantes ortotópicos de hígado que evolucionan asintomáticos en pacientes con complicaciones por cirrosis. Las complicaciones postoperatorias tempranas fueron del 40%, la más frecuente la infección del sitio operatorio (14%) y cálculos residuales (9%). La complicación tardía más usual fue la litiasis residual (23%). El 80% de los pacientes operados están asintomáticos comparados con el 72% de los no operados. No hubo mortalidad quirúrgica. Conclusiones: La hepatolitiasis es una entidad con manejos no bien estandarizados, entre ellos, la opción quirúrgica cursa con buenos resultados, mejoría clínica y poca morbimortalidad; con el apoyo interdisciplinario dado la radiología intervencionista y la endoscopia biliar.

Objectives: Evaluate the results of interdisciplinary care in a series of patients with hepatolithiasis. Patients and Methods: A retrospective study of 53 patients with hepatolithiasis who were evaluated over an eight year period. Results: 23 men (43%) and 30 women were studied. The average age was 50 ± 15 years (range: 25-83 years). Pain was the predominant symptom (94%), followed by jaundice (68%) and fever (57%). According to the Tsunoda classification, 6 patients were Tsunoda I, 12 were Tsunoda II, 4 were Tsunoda III, and 5 were Tsunoda IV. Left lobe hepatolithiasis was most frequent (36%), followed by bilateral hepatolithiasis (34%). Endoscopic cholangiography was successful in 64% of patients. Only 4 patients were treated by percutaneous cholangiography, with 2 successes. 35 patients (66%) were operated on. The most frequent surgery was left hepatectomy with subcutaneous loop in 7 patients (40%), followed by hepatojejunostomy with subcutaneous loop (26%). Four orthotopic liver transplantations with good evolution were performed in patients with cirrhotic complications. 40% had early complications. Most frequent were infection of the operative site (14%) and residual stones (9%). The most frequent delayed complication was residual lithiasis (23%). 80% of the patients who underwent surgery were asymptomatic compared with 72% of those who did not undergo surgery. There were no mortalities resulting from surgery. Conclusions: Hepatolithiasis is a disease which does not have a well standardized treatment. Surgery is an alternative with good results, clinical improvement and low morbidity and mortality rates when there is interdisciplinary including interventionist radiology and biliary endoscopy.
