Reparación laparoscópica de las lesiones quirúrgicas de la vía biliar: factibilidad y evaluación de resultados / Laparoscopic repair of bile duct injuries: Feasibility and outcomes

Introducción: Las lesiones quirúrgicas de la vía biliar (LQVB) posteriores a la colecistectomía videolaparoscópica tienen una incidencia de 0,6% aproximadamente, siendo por lo general más graves y complejas. La hepaticoyeyunoanastomosis (HYA) en Y de Roux es la mejor opción terapéutica (tasas de éxito entre 75-98%). Algunas series demostraron factible el abordaje laparoscópico en la resolución de esta patología. El objetivo es describir nuestra experiencia en la reparación laparoscópica de las LQVB. Métodos: Estudio retrospectivo y descriptivo. Se incluyeron pacientes sometidos a reparación laparoscópica posterior a LQVB. Se analizaron variables demográficas, clínicas, quirúrgicas y posoperatorias. Se aplicaron análisis estadísticos descriptivos. Resultados: Se evaluaron 92 pacientes con LQVB; 81 se sometieron a reparación quirúrgica, ocho fueron candidatos a HYA laparoscópica (aplicabilidad 9,88%). En 75% (seis) se logró una reparación laparoscópica completa. La mayoría eran mujeres (75%). Edad promedio de 40,8 ± 16,61 años (rango 19-65). Las lesiones Strasberg-Bismuth ≥ E3 afectaron a 25% (dos). En la mitad se realizó una HYA laterolateral según la técnica de Hepp-Couinaud; tres usuarios recibieron una HYA terminolateral y otro una bi-HYA terminolateral en Y de Roux. El tiempo operatorio promedio fue de 260 min (rango 120-360). La morbilidad global fue de 37,5% (tres casos): dos complicaciones menores (bilirragia grado A y hemorragia por drenajes) y una mayor (bilirragia grado C). No se registró mortalidad. El seguimiento máximo fue de 26 meses (rango 6-26). Conclusiones: Nuestro estudio muestra que, en un grupo seleccionado de pacientes, la HYA laparoscópica es factible, con los beneficios de un abordaje miniinvasivo.(AU)

Introduction: Bile duct injuries (BDI) following laparoscopic cholecystectomy occurs in approximately 0.6% of the cases, often being more severe and complex. Roux-en-Y hepaticojejunostomy (RYHJ) is considered the optimal therapeutic option, with success rates ranging from 75% to 98%. Several series have demonstrated the advancements of the laparoscopic approach for resolving this condition. The objective of this study is to describe our experience in the laparoscopic repair of BDI. Methods: A retrospective, descriptive study was conducted, including patients who underwent laparoscopic repair after BDI. Demographic, clinical, surgical, and postoperative variables were analyzed using descriptive statistical analyses. Results: Eight patients with BDI underwent laparoscopic repair (out of 81 surgically repaired patients). Women comprised 75% of the sample. A complete laparoscopic repair was achieved in 75% (6) of cases. The mean age was 40.8 ± 16.61 years (range 19–65). Injuries at or above the confluence (Strasberg–Bismuth ≥ E3) occurred in 25% of cases (2). Primary repair was performed in two cases. Half of the cases underwent a Hepp-Couinaud laterolateral RYHJ, while three patients received a terminolateral RYHJ, and one underwent a bi-terminolateral RYH. The mean operative time was 260 min (range 120–360). Overall morbidity was 37.5% (three cases): two minor complications (bile leak grade A and drainage-related bleeding) and one major complication (bile leak grade C). No mortality was recorded. The maximum follow-up period reached 26 months (range 6–26). Conclusions: Our study demonstrates the feasibility of laparoscopic RYHJ in a selected group of patients, offering the benefits of a minimally invasive approach.(AU)

Symptomatic polycystic liver disease: a rare indication of hepatectomy.

We present the case of forty-four-year-old woman with autosomal dominant Polycystic liver disease (PLD) without kidney disease diagnosed for 18 years ago. She experienced progressive abdominal distension and malnutrition over the previous twelve months. The patient had no other comorbidities. Physical examination revealed an 8 cm hepatomegaly in the right hypochondrium region. Liver function analysis was normal. CT scan showed multiple liver cysts with smooth and regular walls, predominantly in the right lobe which was considered as type III according to Gigot´s classification. Due to the significant hepatomegaly, conventional surgery was performed. Exploration showed multiple cysts of varying sizes on the liver surface, with diffuse involvement of the right hemiliver. Standard right lobe mobilization was technically not possible. Fenestration was performed in dominant superficial cysts, to allow access to the deeper cysts and liver parenchyma. A right hepatectomy was carried up using ultrasound devices and ultrasonic aspirator. And the biggest cysts located in the surface of left hepatic lobe were surgically unroofed. No surgical complications occurred, and the patient was discharged 5 days after the intervention.

[Primary neuroendocrine tumor of the common bile duct] / Tumor neuroendocrino primario del conducto hepático común.

Primary neuroendocrine tumors (NETs) of the bile duct are extremely rare and represent only 0.2-2% of all gastrointestinal NETs. Within the biliary system, the main bile duct is the most affected site. A 28-year-old man with a 6-month history of intermittent jaundice, pruritus, and choluria. MRCP, PET-CT and endoscopic ultrasound were performed. A well-differentiated neuroendocrine neoplasia was diagnosed. Complete resection of the main bile duct was performed with lymphadenectomy of the hepatic pedicle with Roux-en-Y hepaticojejunostomy, without complications. The patient had an adequate evolution and nowadays he's disease-free. Primary neuroendocrine tumors of the bile duct are extremely rare. They may present clinically and radiologically similar to perihilar cholangiocarcinoma, which makes preoperative diagnosis difficult. Radical resection is indicated. Usually, they are well differentiated tumors, being the Ki-67 labeling index a reliable prognostic marker.

Los tumores neuroendocrinos (TNE) primarios de la vía biliar son extremadamente raros y representan sólo el 0.2-2% de todos los TNE gastrointestinales. Dentro del sistema biliar, la vía biliar principal es el sitio más afectado. Hombre de 28 años con cuadro de 6 meses de evolución caracterizado por ictericia intermitente, prurito y coluria. Se realizó colangiopancreatoresonancia magnética nuclear, PET-TC y ultrasonido endoscópico que concluyeron neoplasia neuroendocrina bien diferenciada. Se realizó resección completa de la vía biliar principal con linfadenectomía del pedículo hepático con hepaticoyeyunoanastomosis en Y de Roux, sin complicaciones. El paciente cursó adecuada evolución y se encuentra libre de enfermedad. Los tumores neuroendocrinos primarios de la vía biliar son extremadamente raros, presentándose clínica y radiológicamente como lesiones similares al colangiocarcinoma perihiliar lo que dificulta el diagnóstico preoperatorio. Está indicado su tratamiento quirúrgico radical. Suelen ser bien diferenciados, siendo el antígeno Ki-67 un marcador pronóstico confiable.

Lesión quirúrgica de vía biliar compleja. Manejo conservador / Complex bile duct injury. Conservative management

RESUMEN La colecistectomía laparoscópica es el tratamiento de elección para la litiasis vesicular sintomática. Aunque la tasa de complicaciones es baja, las lesiones de la vía biliar representan un grave problema. La asociación con una lesión vascular (lesión compleja) genera un impacto adicional, disminuyendo la calidad de vida y la sobrevida a largo plazo. Presentamos el caso de una paciente con lesión compleja por compromiso vascular del pedículo hepático derecho que desarrolló una atrofia del parénquima correspondiente. Ante la ausencia de complicaciones sépticas, el tratamiento no operatorio pudo realizarse en forma exitosa.

ABSTRACT Laparoscopic cholecystectomy is considered the standard of care for symptomatic cholelithiasis. Although the rate of complications is low, bile duct injuries represent a serious problem. The association with vascular injury (complex injury) poses an additional impact by reducing the quality of life and long-term survival. We report the case of a female patient with complex injury due to vascular involvement of the right hepatic pedicle who developed right liver atrophy. Non-operative management was successful due to the absence of septic complications.

Hepatectomía asociada a resección venosa portal en colangiocarcinoma perihiliar / Hepatectomy associated with protal vein resection in perihilar cholangiocarcinoma

RESUMEN El colangiocarcinoma es una neoplasia infrecuente que, debido a su localización anatómica, plantea una dificultad técnica para su resolución quirúrgica. La cirugía en el colangiocarcinoma perihiliar sigue siendo el único tratamiento curativo con el que se consiguen las mejores tasas de supervivencia a los 5 años. La invasión de la vena porta conlleva la necesidad de asociar una resección portal y su correspondiente reconstrucción. Sin embargo, la invasión tumoral de la vena porta es, en la mayoría de los casos, un hallazgo intraoperatorio, por lo que es importante contar con opciones para eventuales reconstrucciones vasculares. A continuación presentamos un caso de resolución quirúrgica de colangiocarcinoma perihiliar con identificación intraoperatoria de compromiso portal.

ABSTRACT Cholangiocarcinoma is a rare neoplasm and a difficult challenge for the surgeon because of its anatomic location. Surgery remains the only curative option for perihilar cholangiocarcinoma with the best survival rates at 5 years. Portal vein invasion requires portal vein resection and its corresponding reconstruction. However, as portal vein invasion is an intraoperative finding in most cases it is important to count with options for in case vascular reconstructions are needed. We report a case of perihilar cholangiocarcinoma successfully treated with surgery with portal vein invasion identified intraoperatively.

ALPPS como opción quirúrgica en terapia reversa aplicado al tratamiento de las metástasis hepáticas del cáncer rectal sincrónico / ALPPS using liver-first reverse approach as a surgical option to treat synchronous colorectal liver metastases

RESUMEN El riesgo de insuficiencia hepática posoperatoria es la limitante de mayor importancia para el trata miento de pacientes con tumores hepáticos malignos primarios o secundarios. Entre las diferentes técnicas para incrementar la resecabilidad de tumores hepáticos se desarrolló una estrategia para pa cientes con tumores previamente considerados como irresecables, técnica conocida como ALPPS (as sociating liver partition with portal vein ligation for staged hepatectomy). Informamos acerca de una cirugía ALPPS en terapia reversa en un hombre referido a nuestro centro con diagnóstico sincrónico de cáncer rectal con metástasis hepáticas múltiples consideradas irresecable al momento del diagnóstico.

ABSTRACT The risk for postoperative liver failure is the most important limitation for the treatment of patients with primary or secondary liver cancer. Among the different strategies used to increase resectability in liver tumors, a technique known as ALPPS (associating liver partition with portal vein ligation for staged hepatectomy) was developed for patients with tumors previously considered unresectable. We report the case of a male patient referred to our center with a diagnosis of synchronous multiple liver metastases of colorectal cancer considered unresectable who underwent ALPPS using liver-first reverse approach.
