Resultados asociados con la realización de colecistectomía subtotal en un hospital de tercer nivel de Bogotá / Results of partial cholecystectomy in a tertiary level hospital in Bogotá

Resumen Introducción: La colecistectomía laparoscópica es actualmente el gold standard en patología vesicular litiásica. Hay un grupo de pacientes que tiene un gran proceso inflamatorio que impide la identificación adecuada del triángulo de seguridad. Dado lo anterior, una alternativa es la realización de colecistectomía subtotal por laparoscopia, para reducir el riesgo de lesión de vía biliar. Objetivo: Describir los resultados clínicos y quirúrgicos en pacientes que se sometieron a la realización de colecistectomía subtotal laparoscópica en el Hospital Universitario Clínica San Rafael en el periodo comprendido entre febrero de 2015 y febrero de 2017. Materiales y Método: Serie de casos, donde se realizó un análisis descriptivo para determinar la distribución de las variables, se utilizaron tablas de contingencia, pruebas Fischer según el caso y su distribución en número y normalidad. Resultados: Se obtuvo información de 28 pacientes, con un promedio de edad de 56,1 años, mayor proporción de hombres. En cuanto a las características clínicas se observaron los antecedentes de diabetes e hipertensión arterial. No hubo complicaciones ni sangrado intraoperatorio importantes. En resultados posoperatorios no se presentó lesión de vía biliar en ninguno, hubo 3 reingresos (10,7%) y hubo una reintervención relacionada con colección intraabdominal. Se reportó una mortalidad secundaria a neumonía. Conclusión: La colecistectomía subtotal es un procedimiento seguro en cuanto a la prevención de lesión de vía biliar.

Introduction: Laparoscopic cholecystectomy is actually the gold standard surgical approach to the gallbladder disease. Some patients with severe cholecystitis and inflammatory changes that makes impossible to dissect the hepatocystic triangle. Is in this case, where the laparoscopic subtotal cholecystectomy is an option, to reduce the risk of biliary injury. Aim: To describe the clinical and surgical results in patients that underwent in laparoscopic subtotal cholecystectomy at Hospital Universitario Clínica San Rafael since February 2015 to February 2017. Materials and Method: A case series study was carried out, with a descriptive analysis to determine the distribution of them. We used contingency tables and fischer tests. Results: 28 laparoscopic subtotal cholecystectomy. The average age of 56.1 years, fifty percent was men. At the clinical characteristics, the history of diabetes and arterial hypertension was observed. There was no bile duct lesion in any and there was a reintervention due to intra-abdominal collection and only one mortality. 50% had biliary leakage and 25% of cases required endoscopic intervention. Conclusion: Laparoscopic subtotal cholecystectomy is a safe procedure.

Alterações histológicas da vesícula biliar de doentes submetidos à colecistectomia por colelitíase / Gallbladder histological alterations in patients undergoing cholecystectomy for cholelithiasis

RESUMO Objetivo: descrever os achados histológicos das vesículas biliares de pacientes submetidos à colecistectomia e avaliar a presença de fatores associados ao câncer incidental da vesícula. Métodos: estudo descritivo, transversal e observacional de 1.278 exames anatomopatológicos de vesículas biliares oriundas de colecistectomias por colelitíase e de seus respectivos laudos, realizadas no período de janeiro de 2008 a dezembro de 2017.

O câncer de vesícula foi identificado em seis pacientes, com prevalência de 0,5% nesta amostra. Houve associação significativa entre a presença de câncer e idade ≥60 anos e com a espessura da parede ≥0,3cm. Conclusão: houve baixa prevalência de câncer de vesícula na população avaliada, maior ocorrência na população idosa e associação de tumor com espessamento da parede vesicular.

ABSTRACT Objective: to describe the histological findings of the gallbladders of patients undergoing cholecystectomy and to evaluate the presence of factors associated with gallbladder incidental cancer. Methods: we conducted a descriptive, cross-sectional, observational study with 1,278 histopathological exams of gallbladders coming from cholecystectomy for cholelithiasis and of their reports, held from January 2008 to December 2017. Results: the most common pathological finding was chronic cholecystitis, present in 1,251 patients (97.8%), followed by gallbladder cholesterolosis, in 131 (10.2%). Gallbladder cancer was identified in six patients, with a prevalence of 0.5% in this sample. There was a significant association between the presence of cancer and age ≥60 years and wall thickness ≥0.3cm. Conclusion: there was low prevalence of gallbladder cancer in this population, higher occurrence in the elderly and association of the tumor with gallbladder wall thickness.

Incidência comparativa de câncer incidental de vesícula biliar em colecistectomias de urgência versus colecistectomias eletivas / Comparative incidence of incidental gallbladder cancer in emergency cholecystectomies versus in elective cholecystectomies

RESUMO Objetivo: analisar, comparativamente, a incidência de câncer incidental de vesícula biliar em colecistectomias de urgência versus colecistectomias eletivas realizadas em hospitais públicos de Teresina-PI. Métodos: estudo observacional descritivo, quantitativo, com delineamento transversal, cujo cenário foram dois hospitais públicos de Teresina-PI. Foram analisados 6.329 prontuários de pacientes submetidos à colecistectomia, entre janeiro de 2011 e dezembro de 2017. Os dados coletados foram divididos em dois grupos e confrontados estatisticamente através do teste Z para diferença entre proporções. Resultados: detectou-se câncer incidental da vesícula biliar em 6,53% das colecistectomias de urgência e em 0,38% das eletivas. Quanto ao sexo, observou-se que, na cirurgia de urgência, 69% eram mulheres e 31%, homens, enquanto no procedimento eletivo, 78% eram mulheres e 22%, homens. Quanto à idade, a maioria dos pacientes possuía mais de 60 anos e, entre estes, 69,3% submetidos à colecistectomias de urgência e 82,6%, à eletivas. O tipo histopatológico "adenocarcinoma" foi encontrado em 84,6% das cirurgias de urgência e 100% das eletivas. Conclusão: câncer incidental de vesícula biliar foi mais frequente em colecistectomias de urgência em comparação às eletivas. O perfil dos pacientes com essa doença maligna nos dois tipos de procedimento foi do sexo feminino, maiores de 60 anos de idade e com diagnóstico histopatológico de adenocarcinoma.

ABSTRACT Objective: to comparatively analyse the incidence of incidental gallbladder cancer in emergency cholecystectomies versus in elective cholecystectomies performed in public hospitals in Teresina city, Piaui state (PI). Methods: descriptive, quantitative, observational, cross-sectional study, whose scenarios were two public hospitals in Teresina-PI. We analysed 6,329 medical records of patients undergoing cholecystectomy between January 2011 and December 2017. The collected data were divided into two groups and statistically compared using Z-test for difference between proportions. Results: incidental gallbladder cancer was detected in 6.53% of emergency cholecystectomies and in 0.38% of elective ones. Regarding gender, it was observed that in emergency surgeries 69% of patients were women and 31% men, while in elective procedures 78% were women and 22% men. Regarding age, most patients were over 60 years old, and, among these, 69.3% underwent emergency cholecystectomies and 82.6% underwent elective cholecystectomies. The histopathological type "adenocarcinoma" was found in 84.6% of patients who underwent emergency surgeries and in 100% of patients who underwent elective surgeries. Conclusion: incidental gallbladder cancer was more frequent in urgent cholecystectomies compared to elective cholecystectomies. The profile of patients with this malignant disease in both types of procedure was female, older than 60 years, and with histopathological diagnosis of adenocarcinoma.

Vesícula biliar gigante / Giant gallbladder

Se registra el caso de una paciente femenina de 73 años con antecedente de colecistitis crónica, quien al examen físico presentaba una tumoración palpable en hipocondrio derecho que se extendía a fosa ilíaca derecha. La ecografía abdominal mostró aumento del tamaño vesicular que alcanzaba fosa ilíaca derecha con contenido multilitiásico; se confirmó dicho hallazgo con estudio tomográfico. Se realizó laparotomía exploradora con hallazgo operatorio de vesícula gigante de paredes engrosadas, tensa, adherida a órganos circundantes, de dificultosa disección, que requirió punción para drenaje de su contenido. Se efectuó, además, colecistectomía convencional según técnica de Pribram, y se obtuvo una pieza quirúrgica de aproximadamente 15 × 10 cm, con informe de anatomía patológica de colecistitis crónica. En contraste con la presentación habitual de la colecistitis crónica, el caso de referencia obedece a una presentación atípica con una vesícula gigante.

We report the case of a 73-year old female patient with a history of chronic cholecystitis with a palpable mass extending from the right hipochondrium to the right iliac region. An abdominal ultrasound showed an enlarged gallbladder extending to the right iliac region with multiple gallstones confirmed by computed tomography scan. An exploratory laparotmy was performed. A giant gallbladder with thickened walls and presence of adhesions to the neighbor organs that were difficult to remove were found and required drainage. A conventional cholecystectomy was performed using the Pribram's technique. A surgical specimen measuring 15 x 10 cm was sent to the pathologist who made a diagnosis of chronic cholecystitis. This case is an atypical presentation of chronic cholecystitis due to a giant gallbladder.

Peritonitis manejada por laparoscopia como método terapéutico eficaz / Peritonitis treated by laparoscopy as an effective treatment

La peritonitis es una de las principales complicaciones de las urgencias abdominales. La laparoscopia sirve tanto para el manejo diagnóstico y terapéutico del abdomen agudo; en manos expertas la morbimortalidad de este método es mínima. Objetivo: El objetivo es comprobar la eficacia de la laparoscopia en pacientes con peritonitis secundaria realizando una sola cirugía sin necesidad de reintervenciones, asegurando el menor daño de la pared abdominal, evitando la laparotomía. Materiales y métodos: Estudio retrospectivo, se incluyeron pacientes con diagnostico final de peritonitis y manejados con técnica laparoscópica, abarcando un periodo de mayo del 2011 a julio del 2016, ingresados a la Clínica Nuestra Señora de Fátima, Pasto, Colombia. Resultados: La muestra fueron 67 pacientes. Los resultados indican una edad promedio de 45 años, edad máxima 94 y mínima 17 años, ± de 20,6; predomina el sexo Femenino en un 55,2% (n=37); siendo el 73,1% (n=49) del área urbana. El tiempo de evolución promedio de la patología fue de 4 días. No hubo casos de mortalidad en la población objeto de estudio. Conclusión: La técnica laparoscópica, el lavado exhaustivo de la cavidad abdominal, la inserción del dren mixto y el tratamiento adecuado de antibiótico, se constituye en una técnica segura en el paciente ya que evito reintervenciones quirúrgicas, riesgo de infecciones, ausencia de íleo paralitico y sangrado, evitando así la laparostomía y el defecto gigante de la pared abdominal.

Peritonitis is one of the main complications of abdominal emergencies. Laparoscopy serves both for the diagnostic and therapeutic management of the acute abdomen; in expert hands the morbimortality of this method is minimal. Objective: The objective is to verify the efficacy of laparoscopy in patients with secondary peritonitis performing a single surgery without the need for reinterventions, ensuring the least damage of the abdominal wall, avoiding laparotomy. Material and methods: Retrospective study included patients with final diagnosis of peritonitis and managed with laparoscopic technique, covering a period from May 2011 to July 2016, admitted to Clínica Nuestra Señora de Fátima, Pasto, Colombia. Results: The sample was 67 patients. The results indicate an average age of 45 years, maximum age 94 and minimum 17 years, ± 20.6; female sex predominates in 55.2% (n = 37); being 73.1% (n = 49) of the urban area. The mean evolution time of the disease was 4 days. There were no cases of mortality in the study population. Conclusion: The laparoscopic technique, thorough cleaning of the abdominal cavity, insertion of the mixed drainage and adequate antibiotic treatment, constitutes a safe technique in the patient since it prevents surgical reinterventions, risk of infections, absence of paralytic ileus and bleeding, thus avoiding laparostomy and the giant defect of the abdominal wall.

Prevalência do câncer de vesícula biliar em pacientes submetidos à colecistectomia: experiência do Hospital de Clínicas da Faculdade de Ciências Médicas da Universidade Estadual de Campinas - UNICAMP / Prevalence of gallbladder cancer In patients submitted to cholecystectomy: experience of the University Hospital, Faculty of Medical Sciences, State University of Campinas - UNICAMP

RESUMO Objetivo: estudar a prevalência do câncer de vesícula biliar em pacientes submetidos à colecistectomia no Hospital de Clínicas da Universidade Estadual de Campinas. Métodos: estudo de prevalência retrospectivo a partir da análise de laudos de espécimes histopatológicos de pacientes submetidos à colecistectomia, no período de janeiro de 2010 a maio de 2015. Resultados: foram analisados 893 laudos de pacientes submetidos à colecistectomia, dos quais 144 de urgência e 749 eletivas (16,2% e 83,8%, respectivamente). Segundo o sexo, 72,8% correspondiam ao feminino e 27,2%, ao masculino. Em 12 pacientes (1,3%) foi evidenciado o diagnóstico de adenocarcinoma de vesícula biliar e, em um (0,1%), o diagnóstico de linfoma não Hodgkin. Dos 13 pacientes com neoplasia, sete (53,8%) apresentaram colecistolitíase associada. Em dois doentes (15,3%) foi constatado pólipo de vesícula biliar. Sete (53,8%) doentes foram operados com a hipótese diagnóstica de neoplasia de vesícula biliar. Conclusão: a prevalência do adenocarcinoma de vesícula biliar no presente estudo foi semelhante à dos estudos ocidentais e o principal fator de risco foi a colecistolitíase, seguido pela presença de pólipos de vesícula biliar.

ABSTRACT Objective: to evaluate the prevalence of gallbladder carcinoma in patients submitted to cholecystectomy for chronic cholecystitis at the University Hospital of the State University of Campinas. Methods: we conducted a retrospective prevalence study through the analysis of histological specimens from January 2010 to May 2015. Results: we analyzed 893 patient reports. Emergency cholecystectomies amounted to 144, and elective ones, 749 (16.2% and 83.8%, respectively). Regarding gender, 72.8% were female and 27.2% male. Gallbladder adenocarcinoma occurred in 12 patients (1.3%) and non-Hodgkin's lymphoma in one (0.1%). In patients with cancer, seven (53.8%) were associated with cholelithiasis and two (15.3%) with gallbladder polyps. Conclusion: prevalence results of gallbladder adenocarcinoma in this study were similar to those of Western studies and the main risk factor was cholelithiasis, followed by the presence of gallbladder polyps.

Obstrução e perfuração jejunal e ileal por cálculos advindos de fístula colecistoduodenal: relato de caso / Jejunal and ileal obstruction and perforation by calculus from cholecysto-duodenal fistula: case report

Introdução: íleo biliar é complicação de colecistopatia calculosa devido à comunicação anormal entre a via biliar e o trato gastrintestinal, com migração de um ou mais cálculos de grandes dimensões para os segmentos intestinais. Esse cálculo segue o trajeto intestinal até encontrar um ponto a partir do qual não consegue mais progredir, provocando obstrução. É mais comum a colecistite aguda ser complicada com fístulacolecistoduodenal com migração de cálculo maior que 2 cm para o delgado e sua impactação na válvula ileocecal e obstrução intestinal. É mais prevalente em idosos, acometendo quatro mulheres para cada homem e de mortalidade elevada especialmente pela faixa etária acometida e pelo diagnóstico difícil e tardio. Relato de caso: 57 anos, feminino, com abdome agudo decorrente de colecistite aguda complicada com fístula colecistoduodenal e impactação de dois cálculos biliares com cerca de 3 cm em jejuno e íleo, seguida de obstrução intestinal e perfuração de ambos os segmentos de delgado. Foi realizada enterectomia segmentar de jejuno, retirada dos cálculos por propulsãomanual retrógrada, anastomose primária, desbridamento e rafia da perfuração ileal. Conclusão: o diagnóstico precoce do íleo biliar é relevante, pois se associa a altas taxas de morbidade e mortalidade, sendo seu tratamento eminentemente cirúrgico.

Introduction: Biliary ileum is a complication from the calculus cholecystopathy due to abnormal communication between the biliary via and the gastrintestinal tract, with the migration of one or more huge calculi to the intestinal segments. This calculus follows the intestinal journey until it finds a point where it can no longer progress, causing obstruction. It is more common that the acute cholecystitis be complicated with a cholecysto-duodenal fistula with migration of a calculus higher than 2 cm for the small intestine and its impact on the ileocecal valve and intestinal obstruction. This is more prevalent in aged people, in four women toevery man and with a high mortality mainly for the age range under issue and by the difficult and late diagnosis. Case report: A 57-year-old female with acute abdomen due to a complicated acute cholecystitis with cholecysto-duodenal fistula and impact on two biliary calculi of about 3 cm in the jejune and ileum, followed by intestinal obstruction and perforation of both small intestine segments. Jejunal segmentar enterectomy, withdrawal of calculi by retrograde manual propulsion, primary anastomosis, debridement, and ileal perforation raffia were carried out. Conclusion: Early diagnosis of the biliary ileum is relevant because it is associated with high morbidity and mortality rates, and its treatment should be surgical.

Simultaneous Xanthogranulomatous Cholecystitis and Gallbladder Cancer in a Patient with a Large Abdominal Aortic Aneurysm

There have been reports of the coexistence of abdominal aortic aneurysm (AAA) with intra-abdominal malignancy including gastric, colonic, pancreatic, and renal. We herein report a case of a previously undiagnosed AAA and a presenting complaint consistent with acute cholecystitis. Following cholecystectomy, this was noted to be a rare form of chronic cholecystitis: xanthogranulomatous cholecystitis. There is a known possible association of this uncommon condition with gallbladder cancer. The management of concomitant pathologies can present a real challenge to the multidisciplinary team, especially with large aneurysms.

Etiology, Clinical Features, and Endoscopic Management of Hemobilia: A Retrospective Analysis of 37 Cases / 대한소화기학회지

BACKGROUND/AIMS: Hemobilia is a rare cause of upper gastrointestinal bleeding. Endoscopic retrograde cholangiopancreaticography (ERCP) is considered to be an excellent diagnostic and treatment modality. Thirty-seven cases of hemobilia with different underlying pathologies were analyzed to illustrate clinical features and to evaluate the role of endoscopic management. METHODS: A total of 37 patients (26 men and 11 women; mean age, 66.2+/-15.3 years) who were confirmed to have hemobilia by ERCP in a single center from 2000 to 2010 were reviewed retrospectively. Patients with iatrogenic causes of hemobilia were excluded in this study. RESULTS: The causes of hemobilia were hepatocellular carcinoma in 14, bile duct and gallbladder malignancies in 12, common bile duct stones with cholangitis in 4, acute cholecystitis in 4, and pancreatic cancer in 2 patients. The clinical features of hemobilia were jaundice (89.2%), abdominal pain (78.4%), and melena (13.5%). The cholangiographic findings of hemobilia were amorphous filling defects in 15, tubular filling defects in 6, and cast-like filling defects in 6 patients. Endoscopic management included endoscopic nasobiliary drainage in 26 patients and endoscopic retrograde biliary drainage in 7 patients. Biliary obstruction caused by hemobilia was successfully treated with endoscopic biliary drainages in most cases. CONCLUSIONS: The most common non-iatrogenic causes of hemobilia were hepatobiliary malignancies, and the majority of patients presented with jaundice and abdominal pain. Endoscopic biliary drainage is recommended as the initial management to control biliary obstruction.

Spontaneous cholecystocutaneous fistula in a case of chronic colculous cholecystitis--a case report.

Chronic calculous cholecystitis is quite a common disease entity today. However, advances in diagnostic imaging and use of broad-spectrum antibiotics have facilitated its early detection and treatment. Hence complications of untreated calculous cholecystitis have shown a steady decline. Spontaneous cholecystocutaneous fistula is one such rare complication. A 45-year-old female presented with acute onset of pain and swelling in the right hypochondrium. She had leucocytosis. The swelling ruptured spontaneously and 200 ml frank yellow pus along with multiple stones were expelled from the site. Completion drainage was done. A fistulogram confirmed the diagnosis of a cholecystocutaneous fistula. The patient underwent open cholecystectomy and excision of the fistulous tract.

Objetivo: descripción de un caso de mucocele apendicular y colecistitis aguda gangrenada, atendido en el Hospital de Especialidades, Centro Médico Nacional Siglo XXI, IMSS. Caso clínico: hombre de 80 años de edad que ingresó al hospital con diagnóstico de colecistitis aguda y tumor abdominal de etiología desconocida, dolor abdominal de 10 días de evolución localizado en hipocondrio derecho, sin fiebre ni pérdida importante de peso. Los exámenes de laboratorio mostraron únicamente leucocitosis moderada. La tomografía computarizada abdominal mostró vesícula biliar con paredes engrosadas y datos de agudización, así como tumor abdominal en fosa iliaca derecha. Se exploró quirúrgicamente con los siguientes hallazgos: colecistitis aguda supurada y tumoración apendicular de 20 cm de longitud, sin datos de malignidad. Se realizó colecistectomía y apendicectomía. El periodo posoperatorio transcurrió sin incidentes. El diagnóstico histopatológico fue de mucocele apendicular no roto. El paciente fue dado de alta a los cinco días. Pasados cinco meses de la intervención, se encontraba asintomático.

OBJECTIVE: We present a case report of appendiceal mucocele and gangrenous cholecystitis. SETTING: Hospital de Especialidades, Centro Médico Nacional Siglo XXI, México, D.F. CLINICAL CASE: An 80-year-old man was admitted to the hospital with diagnosis of acute cholecystitis and abdominal tumor under study, with complaints of abdominal pain for 10 days located in the right upper quadrant, without fever or significant weight loss. Laboratory analyses revealed moderate leucocytosis. CT of the abdomen revealed thickening of the gallbladder wall and acute local inflammation, as well as the presence of abdominal tumor in the right lower quadrant. The patient was surgically explored with the following findings: gangrenous cholecystitis and appendiceal tumor of 20 cm length. Cholecystectomy and appendectomy was performed. The postoperative period was normal. The final histological report was appendiceal mucocele and the patient was discharged after 5 days. The patient is currently without complaints at 5 months postoperatively.

Spontaneous cholecystocutaneous fistula: a rare complication of gallbladder disease / Fistula colecistocutânea espontânea: uma rara complicação da colecistopatia crônica calculosa

CONTEXT: Spontaneous cholecystocutaneous abscess or fistula is an extremely uncommon complication secondary to cholecystitis. Over the past 50 years fewer than 20 cases of spontaneous cholecystocutaneous fistulas have been described in the medical literature. We here report a case of subcutaneous gallstone as a rare clinical presentation of the already uncommon cholecystocutaneous fistula. CASE REPORT: An 81-year-old man presented with a large subcutaneous abscess in the right subcostal area with surrounding cellulitis and crepitus. An abdominal computed tomography scan showed two subcutaneous gallstones and communication between the abscess and the gallbladder. Cholecystectomy was performed and the abdominal wall abscess was drained externally. This case report demonstrates that maintaining a high degree of suspicion of this rare entity is helpful in achieving correct preoperative diagnosis, and that computed tomography scan should be performed in all cases of unexplained abdominal wall suppuration or cellulitis.

CONTEXTO: A fístula e/ou o abscesso colecistocutâneo são complicações extremamente raras da colecistopatia crônica calculosa. Nos últimos 50 anos, menos de 20 casos de fistulas colecistocutâneas foram descritos na literatura médica. Nós descrevemos um caso de cálculos biliares no tecido subcutâneo como rara apresentação clínica de fístula biliar. RELATO DO CASO: Paciente de 81 anos deu entrada no serviço de emergência apresentando um grande abscesso na região de hipocôndrio direito. A tomografia computadorizada de abdome demonstrou a presença de dois cálculos no tecido celular subcutâneo e a comunicação da vesícula biliar com a parede abdominal. O paciente foi submetido a uma colecistectomia e drenagem externa do abscesso da parede abdominal. Este caso demonstra que um alto grau de suspeita desta rara complicação da colecistopatia crônica calculosa é fundamental para o correto diagnóstico pré-operatório, e a tomografia computadorizada deve ser realizada rotineiramente em todos os casos de abscessos de parede abdominal de origem indeterminada.
