Síndrome de Mirizzi grado IV. Presentación de un caso

El Síndrome de Mirizzi es una afección derivada del impacto de un lito en el conducto cístico o infundíbulo de la vesícula biliar. La enfermedad litiásica, crónica y complicada de la vesícula biliar es un factor determinante. Se presenta el caso de un paciente con historia de íctero obstructivo, al cual se le diagnosticó inicialmente tumor periampular. Fue reevaluado y se le realizaron varias pruebas diagnósticas, hasta llegar al diagnóstico de Síndrome de Mirizzi, corroborado en el acto quirúrgico. El SM es una enfermedad rara de la vía biliar cuyo tratamiento es quirúrgico. La vía laparoscópica para la realización de la colecistectomía es la de elección para casos grado I y en casos seleccionados grado II. La colecistectomía y derivación bilioentérica (hepaticoyeyunostomía) conforman el tratamiento para el resto de los casos.

Mirizzi Syndrome is a condition derived from the impact of a stone in the cystic duct or infundibulum of the gallbladder. Chronic and complicated stone disease of the gallbladder is a determining factor. A patient with a history of obstructive jaundice, who was initially diagnosed with a periampullary tumor is presented. He was reassessed and several diagnostic tests were performed, until reaching the diagnosis of Mirizzi Syndrome, corroborated in the surgical act. MS is a rare disease of the bile duct whose treatment is surgical. The laparoscopic approach to perform cholecystectomy is the one of choice for grade I cases and in selected cases grade II. Cholecystectomy and bilioenteric bypass (hepaticojejunostomy) are the treatment for the rest of the cases.

Minimally invasive management of Mirizzi syndrome Va: Case series and narrative review of the literature.

INTRODUCTION: Mirizzi's Syndrome (MS) is a rare pathology, known to be a challenge for the surgeon. In the surgical management, open approach vs laparoscopic is a topic of discussion due to anatomic variations. The aim of this study is to analyze our experience in the laparoscopic management of this condition in Type Va. METHODS: We made a descriptive retrospective study of patients diagnosed with MS type Va and treated by laparoscopic approach from 2014 to 2019, in two high volume centers of Bogotá, Colombia. RESULTS: 1073 patients who presented complications from gallstones were evaluated, of which 16 were diagnosed with MS type Va. 75% were females and 25% males; 80% presented jaundice and 90% abdominal pain; 12 patients showed cholecystoduodenal fistula and 4 cholecystocolic fistula. All patients underwent laparoscopic management, total cholecystectomy and fistula resection with primary closure was possible on a 100% of the patients. Conversion rate was 0%. The follow up was 18 months. CONCLUSION: Laparoscopic management of MS is feasible and safe; the experience of the surgery group and selection of the patients is the key to a successful outcome.

Role of laparoscopy in the treatment of internal biliary fistulas in a high-volume center and a review of the literature.

BACKGROUND: Biliary fistulas may result as a complication of gallstone disease. According to their tract, abdominal internal biliary fistulas may be classified into cholecystobiliary and bilioenteric fistulas. Surgical treatment is challenging and requires highly trained surgeons with high preoperative suspicion. Conventional surgery is still of choice by most of the authors. However, laparoscopy is emerging as a minimally invasive alternative. We investigated the surgical approach, conversion rate, and outcomes according to the type of biliary fistula. METHODS: We retrospectively reviewed 11,130 laparoscopic cholecystectomies, 31 open cholecystectomies, and 31 surgeries for gallstone ileus at our institution from May 2007 to May 2020. We diagnosed internal biliary fistula in 73 patients and divided them into two groups according to their fistulous tract: cholecystobiliary fistula and bilioenteric fistula. We described demographic characteristics, preoperative imaging modalities, surgical approach, conversion rates, surgical procedures, and outcomes. We additionally revised the literature and compared our results with 13 studies from the past 10 years. RESULTS: There were 22 and 51 patients in the cholecystobiliary and bilioenteric groups, respectively. Our preoperative suspicion of a fistula was 80%. We started 88% of procedures by laparoscopic approach. The effectiveness of laparoscopy in the resolution of internal biliary fistula was 40% for cholecystobiliary fistula and 55% for bilioenteric fistulas. The most frequent cause for conversion to laparotomy was the difficulty to identify anatomical features, in addition to the need to perform a Roux en-Y hepaticojejunostomy. Choledocholithiasis was not associated with an increase in conversion rates. CONCLUSIONS: Laparoscopic resolution of a biliary fistula is still a matter of controversy. Despite the high conversion rates, we believe that a great number of patients benefit from this minimally invasive technique. A high preoperative suspicion and trained surgeons are vital in the treatment of internal biliary fistulas.

Síndrome de Mirizzi tipo V: Manejo laparoscópico / Mirizzi syndrome type V: laparoscopic management

Resumen Introducción: El Síndrome de Mirizzi es una complicación infrecuente de la enfermedad litiásica biliar, con una incidencia menor al 1% en países desarrollados, puede desarrollarse en cinco variantes, siendo menos frecuente la variante tipo V. La literatura actual discrepa sobre el manejo de esta condición, afirmando que la cirugía laparoscópica no es segura como procedimiento estándar. Caso Clínico: Se presenta el caso de Síndrome de Mirizzi en un hombre de 80 años, que es remitido al departamento de urgencias por sospecha de sepsis de origen abdominal, con estudio ecográfico de colelitiasis, neumobilia y dilatación de las vías biliares. Se realizó Colangiopancreatografía retrógrada endoscópica con imposibilidad técnica para la movilización y extracción de los cálculos por gran tamaño, recurriéndose a exploración a través de técnica laparoscópica, obteniéndose resultados satisfactorios. Conclusión: Para tratar el Síndrome de Mirizzi, es necesario considerar las características del paciente y la experiencia del cirujano ya que ambos factores influyen directamente en la modalidad del tratamiento, sus complicaciones y tasas de éxito. En el presente caso, la experiencia del autor principal en el manejo de procedimientos mínimamente invasivos y la consideración de reducir el riesgo de complicaciones como infecciones en un paciente frágil, fueron los factores que influyeron para la decisión de intervención laparoscópica.

Abstract Introduction: Mirizzi's syndrome is an infrequent complication of biliary lithiasic disease, with an incidence of less than 1% in developed countries, being even less frequent the type V variant. Current literature disagrees on the management of this condition, stating that laparoscopic surgery is not safe as a standard procedure. Clinical Case: We present the case of Mirizzi's Syndrome in an 80-year-old man, which is referred to the emergency department for suspicion of sepsis of abdominal origin, with ultrasound study of cholelithiasis, pneumoobilia and dilation of the bile ducts. Retrograde endoscopic cholangiopancreatography was performed with technical impossibility for the mobilization and extraction of large-size stones, resorting to exploration through laparoscopic technique, obtaining satisfactory results. Conclusion: It is necessary to emphasize that the type of Mirizzi syndrome, the patient's characteristics and the surgeon's experience directly influence the treatment modality, its complications and/or success rates. In the present case, the experience of the main author in the management of minimally invasive procedures and the consideration of reducing the risk of complications such as infections in a fragile patient, were the factors that influenced the decision for laparoscopic intervention.

Single-operator cholangioscopy and electrohydraulic lithotripsy for the treatment of Mirizzi syndrome.

INTRODUCTION: Mirizzi syndrome is an infrequent complication of long-standing cholelithiasis. Extrinsic compression of the common hepatic duct is usually caused by an impacted stone in Hartmann's pouch or cystic duct resulting in the development of cholecystobiliary fistula. This syndrome is classified based on the presence and severity of cholecystobiliary fistula. Mirizzi syndrome is challenging to diagnose preoperatively and may require complex biliary surgical procedures for resolution. RESULTS: We present three patients with Mirizzi syndrome with different clinical presentations. All were successfully treated by cholangioscopy with electrohydraulic lithotripsy. Endoscopic treatment is a safe alternative with a high success rate. Single-operator cholangioscopy combined with lithotripsy has been shown to have a 90-100% success rate in the treatment of biliary stones. CONCLUSION: Herein, we present our experience treating Mirizzi syndrome with single-operator cholangioscopy guided electrohydraulic lithotripsy. Difficult management of Mirizzi syndrome has led to research of new treatment options to minimize the risk of high-rate complications. Single-operator cholangioscopy in combination with laser lithotripsy is an adequate and safe alternative for the treatment of this condition.

Mirizzi syndrome from type I to Vb: a single center experience.

OBJECTIVES: The present study describes a cohort of patients diagnosed with Mirizzi syndrome from type I to Vb, over a period of four years. It aimed to identify diagnostic and management pitfalls of Mirizzi syndrome, as well as their concomitant cholecystobiliary or cholecystoenteric fistulas. MATERIAL AND METHODS: We retrospectively reviewed all electronic medical records of patients who underwent surgery for Mirizzi syndrome at a single institution. RESULTS: Twenty-two patients (0.6%) were diagnosed with Mirizzi syndrome. Most of the patients were females (n=19, 86.3%). Mean age was 43.8 years (range: 21-71 years). Ultrasound was performed in all (100%) patients. Six (27.2%) patients had a CT scan and six (27.2%) patients had endoscopic retrograde cholangiopancreatography. Overall preoperative diagnosis was achieved on 36.6% (n=8) of the patients. There were the same total and partial cholecystectomies, accounting for ten (45.5%) cases each, one hepaticojejunostomy with cholecystectomy (4.5%), and one enterolithotomy (4.5%). Laparoscopic cholecystectomy was attempted in 15 (68.1%) patients, with conversion to open surgery in 93.3% (n=14) of the patients. An open approach was made in five (22.7%) cases. Four (18.1%) patients were reported as MS type I, both types II and III each account for 22.7% (n=5) of the cases, there was only one (4.5%) patient with type IV, and seven (31.8%) patients with type V. CONCLUSION: There are limited studies of patients with Mirizzi syndrome, including type V classification, and when this syndrome is suspected, a preoperative diagnosis should be made to avoid bile duct injuries or lesions to adjacent organs.

Síndrome de Mirizzi que simulaba una neoplasia biliar maligna / Mirizzi syndrome simulating a biliary malignant neoplasm

El síndrome de Mirizzi puede cursar con manifestaciones clínicas y hallazgos imagenológicos y de laboratorio, similares a los encontrados en las neoplasias biliares malignas. Se describe el caso de un paciente cuyo enfoque clínico inicial y estudios de imágenes aportaron datos sugerentes de neoplasia de las vías biliares. Los marcadores tumorales (CA 19-9, CEA) resultaron elevados. Una nueva evaluación clínica, la laparoscopia exploradora y la exploración endoscópica de las vías biliares, permitieron establecer el diagnóstico de síndrome de Mirizzi. Después de la extracción del cálculo biliar y de la anastomosis entre el conducto hepático y el yeyuno, el paciente permaneció asintomático. En este caso, la reevaluación clínica y el uso del protocolo adecuado de estudio, contribuyeron a orientar y confirmar el diagnóstico de síndrome de Mirizzi, lo cual determinó la conducta terapéutica más acertada

Mirizzi syndrome can occur with clinical manifestations and imaging and laboratory findings, similar to those found in malignant biliary neoplasms. We describe the case of a patient whose initial clinical approach and imaging studies provided data suggestive of bile duct neoplasia. Tumor markers (CA 19-9, CEA) were high. A new clinical evaluation, an explorative laparoscopy and endoscopic bile duct exploration allowed establish the diagnosis of Mirizzi syndrome. After removal the bile duct stone and to perform an hepatico jejunostomy the patient remained asymptomatic. In this case the clinical reevaluation and the use of the appropriate study proto-col contributed to guide and confirm the diagnosis of Mirizzi syndrome, which determined the most successful therapeutic approach

Mirizzi syndrome grades III and IV: surgical treatment / Síndrome de Mirizzi graus III e IV: tratamento cirúrgico

ABSTRACT Objective : to evaluate the epidemiology and outcomes of surgical treatment of patients with Mirizzi Syndrome (MS) grades III and IV, the most advanced according to Csendes classification. Methods : we conducted a retrospective, cross-sectional study by reviewing records of thirteen patients with grades III and IV MS operated from December 2001 to September 2013, among the 3,691 cholecystectomies performed in the period. Results : the incidence of MS was 0.6% (23 cases) and grades III and IV amounted to 0.35% of this number. There was a predominance of type IV (12 cases). The preoperative diagnosis was possible in 53.8% of cases. The preferred approach was biliary-digestive derivation (10 cases), and "T" tube drainage with suture of the bile duct was the choice in three special occasions. Three patients had biliary fistula resolved with clinical management, and one coliperitoneum case required reoperation. In the outpatient follow-up of patients who underwent biliodigestive anastomosis (eight), 50% are asymptomatic, 25% had anastomotic stricture and 25% lost follow-up. The mean follow-up was 41.8 months. Conclusion : MS in advanced degrees has low incidence, preoperative diagnosis in only half of cases, and has the biliodigestive anastomosis as the best conduct, but not without morbidity.

RESUMO Objetivo: avaliar a epidemiologia e os resultados do tratamento cirúrgico de doentes portadores de graus III e IV, mais avançados, da Síndrome de Mirizzi (SM) de acordo com a classificação de Csendes. Métodos: estudo retrospectivo, de corte transversal através da revisão de prontuários de 13 pacientes portadores de graus III e IV da SM operados de dezembro de 2001 a setembro de 2013, entre 3691 colecistectomias realizadas neste período. Resultados: a incidência da SM foi 0,6% (23 casos) e os graus III e IV perfizeram 0,35% deste número. Houve um predomínio de tipo IV (12 casos). O diagnóstico pré-operatório foi possível em 53,8% dos casos. A conduta preferencial foi derivação biliodigestiva (10 casos) e foi optado por drenagem com tubo "T" e sutura da via biliar em três ocasiões especiais. Três pacientes apresentaram fístula biliar resolvida com conduta expectante e um caso de coleperitônio necessitou reoperação. No seguimento ambulatorial dos pacientes que realizaram a anastomose biliodigestiva (oito), 50% estão assintomáticos, 25% apresentaram estenose da anastomose e 25% perderam seguimento. O tempo médio de acompanhamento foi 41,8 meses. Conclusão: de incidência baixa e de diagnóstico pré-operatório em apenas metade dos casos, a SM em graus avançados tem na anastomose biliodigestiva sua melhor conduta, porém não isenta de morbimortalidade.

Clinical-epidemiological profile of acute appendicitis: retrospective analysis of 638 cases / Perfil clínico-epidemiológico da apendicite aguda: análise retrospectiva de 638 casos

ABSTRACT Objective: to describe the clinical and epidemiological profile of acute appendicitis (AA) of the patients treated at a referral center in the Juiz de Fora macro-region, Minas Gerais State, Brazil. Methods: we conducted a retrospective, observational study in the Dr. Mozart Geraldo TeixeiraEmergency Hospital. We selected 638 patients diagnosed with AA, and analyzed the variables gender, age, evolutionary phase, length of hospital stay, pathological diagnosis, use of antibiotics, use of drains, complications and mortality. Results: AA was more prevalent in young adults (19-44 years) and males (65.20%). The mean hospital stay was seven days and phase II was the most prevalent. We found the histopathological diagnosis of primary tumor of the appendix in six patients (0.94%), adenocarcinoma being the most common histologic type (66.7%). Regarding the use of antibiotics, 196 patients underwent antibiotic prophylaxis and 306 received antibiotic therapy. Eighty-one patients used some kind of drain, for an average of 4.8 days. Seventeen patients died (2.67%), predominantly males (70.59%), with mean age of 38.47 years. Conclusion: AA has a higher prevalence in males and young adults. The length of stay is directly associated with the evolutionary phase. The most common complication is infection of the surgical site. Mortality in our service is still high when compared with developed centers.

Mirizzi Syndrome Type IV: a challenging diagnosis

Mirizzi Syndrome type IV is an extremely rare condition, which is confused with the diagnosis of cholangiocarcinoma in many cases. This report describes a case of a forty-three-year old patient, who was forwarded to our department of general surgery with a high suspicion of a choledochal neoplasic lesion. During the hospitalization he was diagnosed with Mirizzi Syndrome type IV. We concisely describe the case and the literature review about this pathology

Síndrome de Mirizzi tipo IV: diagnóstico y manejo mediante colangiopancreatografía retrógrada endoscópica: reporte de caso / Mirizzi Syndrome Type IV: diagnosis and management through retrograde endoscopic cholangiopancreatography: case report

El síndrome de Mirizzi es una rara complicación de la colelitiasis, caracterizado por obstrucción mecánica del conducto hepatocolédoco por un cálculo impactado en el cístico o en el cuello vesicular. Después de un período de tiempo puede desarrollarse una fístula colecistobiliar por destrucción de la pared del colédoco. Según la clasificación de Csendes, el tipo IV es el menos frecuente. Se presentó un caso con antecedente de colelitiasis que ingresa con cuadro clínico compatible con colangitis aguda. Se realiza CPRE electiva, diagnosticándose síndrome de Mirizzi tipo IV y se coloca prótesis como puente para el tratamiento quirúrgico. Ante un paciente con esas características, la CPRE resulta un método diagnóstico y terapéutico indispensable(AU)

The Mirizzi syndrome is a cholelithiasis rare complication, characterized by the mechanical obstruction of the hepato choledocus duct by a calculus impacted in the cystic or in the vesicular neck. We presented a case with cholelithiasis antecedents entering the hospital with a clinical picture compatible with acute cholangitis. We made an elective cholangiopancreatography finding a big protraction of the intrahepatic biliary tracts, stretch of the supraduodenal choledoc with a common cystic-vesicular neck and choledocian environment, forming a great duct of near 20 mm diameter, having inside an ovoid filling mistake which bigger diameter is 15 mm, directed to the choledocus and to the vesicle. We diagnosed a Mirizzi syndrome Type IV. In a patient with those characteristics, the cholangiopancreatography is an unavoidable diagnostic and therapeutic method(AU)

[Mirizzi syndrome: experience at Spanish Hospital of Veracruz]. / Síndrome de Mirizzi. Experiencia del Hospital Español de Veracruz.

BACKGROUND: Mirizzi syndrome is a complication of gallbladder stones impacted in Hartmann's pouch or cystic duct with compression of the bile duct. The diagnosis is made by imaging studies, although most of them are found through intraoperative surgical findings. Treatment is cholecystectomy and bile duct restoration when needed. OBJECTIVE: to analyze a series of cases of Mirizzi syndrome and compare the results with those published in the literature. CLINICAL CASE: We report 4 cases with Mirizzi syndrome in a cohort of 1,034 cases studied in the Hospital Español of Veracruz over 21 years. RESULTS: In our series the frequency of Mirizzi syndrome was 0.38%, the average age was 32.1 ± 58.4 years, 50% were male gender and 25% had jaundice with a demonstrable liver profile. In 1 case, ultrasound suggested Mirizzi syndrome and percutaneous cholangiography and computed tomography confirmed the diagnosis. All patients underwent laparoscopic cholecystectomy, and 2 transcystic cholangiographies were performed. One case was classified as Type I-A and three as type I-B. (Beltran and Csendes). The postoperative evolution was satisfactory in all and no mortality was presented. CONCLUSIONS: Mirizzi syndrome should be suspected in patients with gallstones who develop obstructive jaundice and it must be confirmed with imaging studies. The surgeon must take extreme precautions to avoid accidental injury to the bile ducts.

Antecedentes: el síndrome de Mirizzi es una complicación de la litiasis vesicular por cálculos impactados en la bolsa de Hartmann o conducto cístico que comprimen la vía biliar principal; el diagnóstico se establece mediante estudios de imagen, aunque la mayor parte son hallazgos transoperatorios; su tratamiento es la colecistectomía con restauración de la vía biliar. Objetivo: analizar una serie de casos de síndrome de Mirizzi y comparar los resultados con lo publicado en la bibliografía mundial. Casos clínicos: se comunican cuatro casos con síndrome de Mirizzi de una cohorte de 1,034 casos con enfermedad litiásica vesicular del Hospital Español de Veracruz, en 21 años. La frecuencia en esta muestra es de 0.38%, con edad promedio de 32.1 ± 58.4 años; 50% son hombres y 25% tuvo ictericia y coluria con perfil hepático demostrativo. En un caso el ultrasonido sugirió síndrome de Mirizzi; el diagnóstico se corroboró por colangiografía percutánea y tomografía computada. A todos los pacientes se les realizó colecistectomía laparoscópica, y en dos se efectuó colangiografía transcística. Un caso correspondió al tipo I-A y 3 al tipo I-B según la Clasificación de Beltrán y Csendes. La evolución postoperatoria fue satisfactoria y no hubo mortalidad.

Antecedentes: El síndrome de Mirizzi (SM) es una alteraciónanatómica de los conductos biliares a nivel de la desembocaduradel cístico, consecuencia tardía de la litiasis vesicular.Objetivo: Determinar el cuadro clínico del SM, clasificarlas lesiones y los resultados inmediatos del tratamiento.Pacientes y método: Estudio descriptivo y retrospectivode corte transversal basado en 16 pacientes (14 mujeres y 2hombres, con edad media de 58 años) intervenidos en el período2005-2010, en quienes se comprobó el SM en el acto operatorio.Resultados: Los síntomas principales fueron dolor e ictericia,La ecografía abdominal reveló colecistolitiasis en 15 (2 consignos inflamatorios agudos) y coledocolitiasis en 1 paciente; eldiámetro del colédoco era mayor a 7 mm en 10 pacientes; en 2pacientes se presumió la existencia del SM.Las lesiones eran de tipo II en el 50% y de tipo III en12.5%. Diez colecistectomías fueron completas y 6 parciales:una de ellas con plastia de la vía biliar principal (VBP) y otracon cierre de fístula duodenal; 8 pacientes fueron sometidos –además de la colecistectomía – a una coledocotomía y extracciónde cálculos.Conclusiones: Las lesiones eran fundamentalmente de tipoII y III; el tratamiento fue la colecistectomía asociada a la coledocotomía,el cierre de fístula colecisto-duodenal y la plastiade la vía biliar.
