Fístula colecistoduodenal sin migración de cálculo: reporte de caso / Cholecystoduodenal fistula without gallstones migration: case report / Fístula colecistoduodenal sem migração de cálculos: relatório de caso

El síndrome de Bouveret es una causa infrecuente de íleo biliar, posee una elevada morbimortalidad. Se produce por la migración de un cálculo, generalmente de gran tamaño, hacia el tracto gastrointestinal a través de una fistula colecistoduodenal. El objetivo de esta carta científica es presentar un paciente con un estadio previo de la enfermedad donde la fistula se encuentra constituida, pero sin migración del cálculo, por lo que el diagnóstico oportuno tendría un impacto favorable en el tratamiento y pronóstico debido a que no se encuentra instaurado el cuadro obstructivo intestinal.

Bouveret's syndrome is a rare cause of biliary ileus, with a high morbimortality. It is caused by the migration of a stone, usually large, into the gastrointestinal tract through a cholecystoduodenal fistula. The objective of this scientific letter is to present a patient with a previous stage of the disease where the fistula is constituted, but without migration of the calculus, so that the timely diagnosis would have a favorable impact on the treatment and prognosis because the obstructive intestinal condition is not established.

A síndrome de Bouveret é uma causa rara de íleo biliar com uma morbilidade e mortalidade elevadas. É causada pela migração de uma pedra, geralmente grande, para o tracto gastrointestinal através de uma fístula colecystoduodenal. O objectivo desta carta científica é apresentar um doente com uma fase anterior da doença em que a fístula está presente, mas sem migração da pedra, para que o diagnóstico atempado tenha um impacto favorável no tratamento e prognóstico, uma vez que a condição obstrutiva instestinal não está estabelecida.

Dilataciones quísticas congénitas de las vías biliares (segunda parte). Vías biliares extrahepáticas / Congenital bile duct cystic dilatations (part 2). Extrahepatic bile ducts

RESUMEN Las dilataciones quísticas congénitas de la vía biliar extrahepática son infrecuentes, principalmente en Occidente, y afectan sobre todo a niños pero son poco comunes en adultos. El diagnóstico requiere un alto índice de sospecha y suele llevarse a cabo con estudios colangiográficos de los cuales la CRMN es, en la actualidad, el de mayor utilidad. Es conocido el aumento de malignización de estas dilataciones, por lo que el tratamiento completo de la bolsa quística es obligatorio.

ABSTRACT Congenital dilatation of extrahepatic bile ducts is rare in the Western countries and is more common in children than in adults. The diagnosis requires high level of suspicion and is made by cholangiography tests, among which MRCP is the most useful nowadays. Malignant transformation of these cystic dilatations is well-known; therefore, complete resection of the cystic pouch is mandatory.

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.

Prevalencia de colecistolitiasis y cáncer de vesícula en una población rural aymara de Chile

Background: The prevalence of cholelithiasis and gallbladder cancer may be different across ethnic groups. Aim: To study the prevalence of cholelithiasis and gallbladder cancer among Aymara individuals. Material and Methods: An abdominal ultrasound was carried out in a sample of 182 Aymara women aged 46 ± 16 years and 76 Aymara men aged 55 ± 16 years. In addition, the histopathological reports of both patients with a history of previous cholecystectomy and those operated after the study were reviewed. Results: Ultrasound was normal in 150 participants (58%), 76 had cholelithiasis (30%) and 32 (12%) had a history of cholecystectomy. Pathological reports of the excised gallbladder were available for 106 cases and showed a chronic cholecystitis in 98% of cases. Gallbladder cancer was not reported. Conclusions: There is a 42% prevalence of cholelithiasis and no gallbladder cancer in this sample of Aymara population.

Colecistitis hemorrágica: reporte de caso y revisión de la literatura / Hemorrhagic cholecystitis: case report and literature review

Resumen Introducción: La colecistitis hemorrágica es una complicación poco frecuente de la colecistitis aguda con una alta mortalidad. Materiales y Método: Paciente con dolor abdominal en hipocondrio derecho e ictericia. Los exámenes de laboratorio y ultrasonido hepatobiliar mostraron datos sugestivos de colecistitis aguda; durante su estancia hospitalaria presenta deterioro de su estado general, realizándose tomografía computarizada mostrando imágenes sugestivas de colecistitis hemorrágica y hemoperitoneo. Resultados: Laparotomía de urgencia, corroborando los hallazgos tomográficos y resolviéndose satisfactoriamente con la colecistectomía. Discusión: El diagnóstico de colecistitis hemorrágica es difícil ya que sus manifestaciones clínicas de inicio no difieren de la colecistitis aguda, por lo que la sospecha clínica y el adecuado estudio de imagen son importantes para su detección. Conclusión: A pesar que la colecistitis hemorrágica con perforación y hemoperitoneo es una patología muy poco común, de diagnóstico confuso, es importante establecer la realización de una tomografía computarizada abdominal con contraste endovenoso en pacientes con sospecha de colecistitis aguda grave.

Introduction: Hemorrhagic cholecystitis is a rare complication of acute cholecystitis with a high mortality. Materials and Method: Patient with abdominal pain in right hypochondrium and jaundice. Laboratory analyses and hepatobiliary ultrasound suggested acute cholecystitis, however, general worsening during hospital stay was observed and a computed tomography was performed, revealing hemorrhagic cholecystitis and hemoperitoneum. Results: Urgent laparotomy which confirmed tomographic results, successfully solved with cholecystectomy. Discussion: Hemorrhagic cholecystitis diagnosis is difficult as symptoms at the beginning do not differ from acute cholecystitis, then, clinical suspicion and a correct image analysis is crucial for its detection. Conclusion: Although, perforated hemorrhagic cholecystitis with hemoperitoneum is a very rare entity with confused diagnosis, an abdominal computed tomography with intravenous contrast is very important in any patient with severe acute cholecystitis suspicion.

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.

Does male gender increase the risk of laparoscopic cholecystectomy? / O gênero masculino aumenta o risco de colecistectomia laparoscópica?

ABSTRACT Background: Laparoscopic cholecystectomy is the preferable treatment for chronic or acute cholecystitis. Some factors may increase the rate of laparoscopic conversion to open cholecystectomy and perioperative complications. The role of gender as a risk factor for laparoscopic cholecystectomy is controversial. Aim: To evaluate the role of the gender on the operative findings and outcome of laparoscopic cholecystectomy. Method: All patients who underwent laparoscopic cholecystectomy for chronic or acute cholecystitis were included. Demographic, clinical, laboratory, imaging exams, intraoperative and postoperative data were obtained and analyzed. The data was obtained retrospectively from electronic medical records and study protocols. Results: Of a total 1,645 patients who were subjected to laparoscopic cholecystectomy, 540 (32.8%) were men and 1,105 (67.2%) were women. Mean age was similar in both genders (p=0.817). Operative time has longer in the male (72.48±28.50) than in the female group (65.46±24.83, p<0.001). The rate of acute cholecystitis was higher in the male (14.3%) than in the female group (5.1%, p<0.001). There was no difference between the genders in regard to the rate of conversion (p=1.0), intraoperative complication (p=1.0), postoperative complication (p=0.571), and operative mortality (p=1.0). Conclusion: Male gender is not an independent risk factor for laparoscopic conversion and perioperative complications.

RESUMO Racional: A colecistectomia laparoscópica é o tratamento de escolha para colecistite crônica ou aguda. Alguns fatores podem aumentar a taxa de conversão para colecistectomia laparotômica e de complicações perioperatórias. O papel do gênero, como um fator de risco para colecistectomia laparoscópica, é controverso. Objetivo: Avaliar o papel do gênero nos achados operatórios e no desfecho da colecistectomia laparoscópica. Métodos: Todos os pacientes que foram submetidos à colecistectomia laparoscópica por colecistite crônica ou aguda foram incluídos. Dados demográficos, clínicos, laboratoriais, de imagem, intraoperatórios e pós-operatórios foram obtidos e analisados. Os dados foram obtidos retrospectivamente a partir de prontuários eletrônicos e protocolos de estudo. Resultados: De um total de 1.645 pacientes que foram submetidos à colecistectomia laparoscópica, 540 (32,8%) eram homens e 1.105 (67,2%) mulheres. A idade média foi semelhante em ambos os gêneros (p=0,817). O tempo operatório foi maior nos homens (72,48±28,50) do que nas mulheres (65,46±24,83) (p<0,001). A taxa de colecistite aguda foi maior no grupo masculino (14,3%) do que no feminino (5,1%, p<0,001). Não houve diferença entre os gêneros quanto à taxa de conversão (p=1,0), complicação intraoperatória (p=1,0), complicação pós-operatória (p=0,571) e mortalidade operatória (p=1,0). Conclusão: O gênero masculino não é fator de risco independente para a conversão laparoscópica e complicações perioperatórias.

Resultado da colecistectomia laparoscópica em idosos / Results of laparoscopic cholecystectomy in the elderly

RESUMO Objetivo: avaliar os resultados da colecistectomia laparoscópica em idosos comparados com pacientes mais jovens. Métodos: revisamos os prontuários médicos informatizados de todos os pacientes submetidos à colecistectomia laparoscópica para colecistite crônica ou aguda, de 1o de janeiro de 2011 a 31 de março de 2018, em um único hospital de ensino. Os pacientes foram estratificados em dois grupos: idosos (≥60 anos de idade) e mais jovens (<60 anos de idade). Resultados: de 1645 pacientes submetidos à colecistectomia laparoscópica, 1161 (70,3%) eram mais jovens e 484 (29,7%) eram idosos. A taxa de homens foi maior nos idosos (n=185, 38,2%) do que no grupo mais jovem (n=355, 30,6%, p=0,003). Icterícia foi mais comum em idosos do que no grupo mais jovem (p=0,004). A taxa de operação abdominal prévia também foi maior nos idosos (<0,001). A porcentagem de pacientes com escore ASA II, III e IV foi maior no grupo de idosos (p<0,001 no escore II e III e 0,294 no escore IV). O tempo de operação foi maior nos idosos (71,68±31,27) do que no grupo mais jovem (p=0,001). Os seguintes dados perioperatórios foram maiores nos idosos: colecistite aguda (p<0,001), taxa de conversão (p=0,028), complicações pós-operatórias (p=0,042) e mortalidade (p=0,026). Conclusão: o tempo operatório é maior e a taxa de colecistite aguda, conversão para colecistectomia aberta e complicações pós-operatórias são maiores em idosos quando comparados com pacientes mais jovens submetidos à colecistectomia laparoscópica.

ABSTRACT Objective: to evaluate the results of laparoscopic cholecystectomy in the elderly compared with younger patients. Methods: we retrospectively reviewed computerized medical records of all patients who underwent laparoscopic cholecystectomy for chronic or acute cholecystitis from January 1, 2011 to March 31, 2018 at a single teaching hospital. We stratified the patients into two groups: elderly (≥60 years of age) and younger (<60 years of age). Results: of 1,645 patients subjected to laparoscopic cholecystectomy, 1,161 (70.3%) were younger and 484 (29.7%) were elderly. The rate of male was higher in the elderly (n=185; 38.2%) group than in the younger (n=355; 30.6) (p=0.003). Jaundice was more common in the elderly (p=0.004). The rate of prior abdominal operation was also higher in the elderly (p<0.001). The percentage of patients with ASA score II, III, and IV was higher in the elderly group (p<0.001 in score II and III and 0.294 in score IV). Operative time was longer in the elderly (71.68±31.27) than in the younger group (p=0.001). The following perioperative data were higher in the elderly: acute cholecystitis (p<0.001), conversion rate (p=0.028), postoperative complications (p=0.042), and mortality (p=0.026). Conclusion: the operative time is longer and the rate of acute cholecystitis, conversion to open cholecystectomy and postoperative complications are higher in the elderly patients submitted to laparoscopic cholecystectomy when compared with younger individuals.

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.

Laparoscopic cholecystectomy for empyema gall bladder

Objective: To describe the experience of treating empyema gall bladder with laparoscopic cholecystectomy. Study Design: Descriptive observational study

Place and Duration of Study: The study was carried out at Combined Military Hospital [CMH] Peshawar, from Feb 2012 till May 2014 for a period of twenty eight months

Material and Methods: Twenty eight patients were enrolled in the study who fulfilled the criteria for empyema and were willing for laparoscopic cholecystectomy, chances of conversion to open cholecystectomy and risk of complications involved. We defined the operative difficulty levels according to the intra-operative findings. Level 1-adherent ornentum, level 2-oedematous gall bladder wall, level 3-necrotic gall bladder wall, level 4-adherent gut and level 5 - adherent Hartmann's pouch and oedematous Calot's triangle having no defined planes. The results were noted in terms of time taken for the operation and complications of the operative procedure. Results: Twenty eight patients of empyema gall bladder underwent laparoscopic cholecystectomy. Mean age was 46.2 +/- 7.1 years. Average duration of symptoms was 4.1 +/-2.3 days. Two patients had level-I operative difficulty, 6 patients had level-II difficulty, 9 patients had level-3 difficulty, 2 patients had level-IV difficulty and 9 patients had level-V difficulty. In 21[75%] patients total cholecystectomy was performed, anterior partial cholecystectomy was done in 2 patients [7.1%] and 5 patients [17.9%] were converted to open cholecystectomy. One patient [3.5%] had Stresburgh Bismuth type D injury and was managed by open exploration and T-tube placement. No mortality was encountered in the study group

Conclusion: The technique of laparoscopic cholecystectomy can be used effectively for treating empyema gall bladder specifically in American Society of Anaesthesiologists [ASA] I and II patients. Further randomized controlled trials can elaborate its efficacy. This will not only prove to be cost effective but it will also add to the comfort of the patient

Frequency of common bile duct injury in laparoscopic cholecystectomy

The aim of the study is to review the frequency of Common Bile Duct [CBD] injury in laparoscopic cholecystectomy [LC] and its management in our set up. This descriptive study was conducted at Surgical Department, Rawalpindi Medical College and the author's Surgical Clinics from January1998 to December 2012. Two thousand patients undergoing laparoscopic cholecystectomy were included in the study. The cases were operated between January 1998 and December 2012. The important variables included were frequency of CBD injury and its management. There were 1723 females and 277 males with mean age 45.04 +/- 11years. 67.8% patients had chronic cholecystitis with cholelithiasis and were admitted through Out Patient Department whereas 32.2% patients were admitted through A and E department. Abdominal ultrasound showed multiple calculi in 1535 [76.7%] patients and 435 [23.3%] patients had single calculus preoperatively. Empyema was found in 245[12.2%] cases whereas adhesions were present in 783[39.1%] patients. Conversion rate to open cholecystectomy was3.4 %. Seventeen cases had CBD injury [0.85%]. 14 cases [82.3%] were diagnosed in traoperatively whereas 3 cases [17.7%] were diagnosed postoperatively. In 13 cases [76.5%] CBD repair was done over T. tube. Mean operating time was 30 minutes. The frequency of CBD injury in LC in our setup was less than 1%and is comparable to international experience. Most of the cases were diagnosed in traoperatively. Repair over T. tube is commonest method employed for management of CBD injury with favorable results

Gallbladder tubrculosis mimicking malignancy: A rare case report.

Summary: Gallbladder tuberculosis is an extremely rare disorder even in endemic region. It often mimics gallbladder malignancy as both of them share some common presentations. This entity is very rarely diagnosed pre-operatively as neither clinical features nor radiology are pathognomonic of gallbladder tuberculosis. The case reported here presented as chronic calculous cholecystitis with mass at gallbladder neck. Patient underwent laparotomy with suspicion of gallbladder carcinoma, which was eventually diagnosed as a case of gallbladder TB following histopathological examination of the resected specimen. He also had pulmonary TB in association and was completely cured with short course antitubercular chemotherapy.

Intraoperative cholangiography during elective laparoscopic cholecystectomy: selective or routine use?

PURPOSE: To investigate clinical, laboratory and ultrasonographic parameters in patients with and without preoperative criteria for intraoperative cholangiography (IOC) during laparoscopic cholecystectomy in order to define predictive factors of choledocolithiasis. METHODS: As a criterion for inclusion in the study the patients should present chronic calculous cholecystitis in the presence or absence of any recent clinical, laboratory of ultrasonographic finding suggesting choledocolithiasis, who were therefore submitted to cholangiography during surgery. RESULTS: A total of 243 laparoscopic cholecystectomies with IOC were performed on patients with chronic calculous cholecystitis with or without a preoperative formal indication for contrast examination. Choledocolithiasis was detected in 33 (13.58%) of the 243 patients studied. The incidence of previously unsuspected choledocolithiasis was only one case (1.0%) among 100 patients without an indication for this exam. However, 32 (22.37%) cases of choledocolithiasis were observed among the 143 patients with a preoperative indication for IOC. CONCLUSION: The use of selective cholangiography is safe for the diagnosis of choledocolithiasis. Only 22.37% of the cholangiography results were positive in cases of suspected choledocolithiasis.

Differential diagnosis and treatment options for xanthogranulomatous cholecystitis

To describe the differential diagnosis and treatment options for xanthogranulomatous cholecystitis [XGC], the presentations and management of 68 patients were described. Demographical and clinical data from 68 cases of XGC treated between January 2004 and January 2010 were analyzed. Clinical characteristics, radiological and surgical findings, histopathological features and postoperative recoveries were recorded. Clinical features of laparoscopic cholecystectomy versus open surgery and XGC versus gallbladder [GB] cancer were compared. The CA19-9 levels of XGC and coexisting GB cancer were significantly different [p = 0.0034]. In radiological findings, focal thickening of the GB wall was more frequent in coexisting GB cancer, early enhancement of the GB was observed more often in coexisting GB cancer, and lymph node enlargement was seen more often in coexisting GB cancer [p < 0.05]. There were also significant differences between laparoscopic and open surgery for CA19-9, intramural hypoattenuated nodule, pericholecystic invasion, lymph node enlargement and maximum thickness, focal thickening, heterogeneous enhancement and early enhancement of the GB wall [p < 0.05]. These findings were confirmed by multivariate analysis. Ultrasound, computed tomography scan and intraoperative frozen section were the helpful modalities for XGC diagnosis. CA19-9 [>37 kU/l], pericholecystic invasion, lymph node enlargement [>10 mm], and focal thickening and early enhancement of the GB wall were the criteria for open surgery. In some selected cases, laparoscopic cholecystectomy was preferable

Laparoscopic cholecystectomy in cirrhotic patients

It was conducted to evaluate laparoscopic cholecystectomy in cirrhotics in terms of procedural safety and better outcome with decreased morbidity. A retrospective, multicenteric study. Surgical Unit-III and IV DHQ Faisalabad. Jan 2000 to Dec 2009. 2610 patients undergoing laparoscopic cholecystectomy from January 2000 to December 2009 for cholecystitis and symptomatic gallstone disease. 61 of the patients being cirrhotics falling in child's class A and B. Evaluation of results was done by analyzing the data in SPSS V-17. Of the 2610 patients who underwent laparoscopic cholecystectomy, 61[2.3%] were cirrhotic. Of these 61, 47[77%] belonged to Childs group A and 14[23%] were group B. Hepatitis C was the major cause of cirrhosis [72%]. Morbidity in cirrhotics was 11.4% in the form of ascities leakage [57%] and port site infection [43%]. Mean hospital stay was 2 +/- 1 days and the mean operative time as 60 +/- 20 minutes in cirrhotics. Laparoscopic cholecystectomy offers a better post op recovery and decreased morbidity in Childs group A and B cirrhotics as it does in non cirrhotic patients

Agenesis of Gall Bladder: Its Emryological Basis and Clinical Significance.

Congenital absence of the gall bladder is a rare anomaly which may occur alone or with other malformations with incidence ranging from 0.01-0.05%. Awareness of this entity by clinicians and radiologists is essential because many of these patients present with biliary symptoms and have unnecessary operations. This presentation, coupled with the inability of standard abdominal ultrasonography to convincingly diagnose agenesis of the gallbladder, can put the surgeon in a diagnostic and intraoperative dilemma. Here we report a suspected case of chronic cholecystitis who underwent a laparoscopic cholecystectomy and was found to have a congenital absence of gall bladder and cystic duct. Standard pre-operative investigative modalities which were fallacious and misleading. The embryological basis and clinical significance have been discussed.

Correlación ecográfica-laparoscópica en colecistitis crónica y aguda: validación 10 años después / Ultrasonographic and laparoscopic correlation in acute and chronic cholecystitis: 10 years later validation

Introduction: Abdominal ultrasound is the initial diagnosis tool for gallbladder disease and laparoscopic surgery is the gold standard approach. The aim of this study was to validate 10 years after, the ultrasonographic and laparoscopic findings previously proposed by our team to forecast laparoscopic cholecystectomy in terms of difficulties and perioperative complications. Materials and Methods: We evaluated 336 patients operated by laparoscopy between June and ¡December 2007 in our center. Ultrasound findings were classified according to the classification proposed in 1997 based on the thickness of the gallbladder wall, lumen and the presence of gallstones or sonic shadow. Results: Type I and IIA cholecystitis had a lower percentage of intraoperative difficulties (14.9 and 32.8 percent respectively) and conversion to open surgery (1.1 vs 1.7 percent respectively), whereas type LIB and III were associated greater presence of difficulties (51.3 percent and 71.4 percent respectively) and conversion rate (9.2 percent and 23.8 percent respectively). Conclusions: this classification is a useful tool in de correlation of ultrasonographic and laparoscopic findings in acute and chronic cholecystitis, helping the surgeon in predicting surgical problems, complications and risk of conversion to open surgery and supports the results previously published.

Introducción: La ecografia abdominal constituye el examen inicial en la patología vesicular; la cirugía laparoscópica es la vía de abordaje de elección. El objetivo de este estudio fue validar, 10 años después, la clasificación ecográfica y su correlación con los hallazgos laparoscópicos, propuesta previamente por nuestro equipo de trabajo para pronóstico de la colecistectomía laparoscópica en cuanto a dificultades y complicaciones peri operatorias. Materiales y Métodos: Se evaluaron 336 pacientes operados por vía laparoscópica entre junio y diciembre de 2007 en nuestro centro. Los hallazgos ecográficos se clasificaron de acuerdo a la clasificación propuesta en 1997, basada en el grosor de la pared vesicular, la presencia de lumen y de cálculos o sombra sónica. Programa Stata 9.1. Se realizó prueba de comparación de proporciones con p < 0,05. Resultados: Las colecistitis tipo I y IIA tuvieron menor porcentaje de dificultades intraoperatorias (14,9 y 32,8 por ciento) y de conversión a cirugía abierta (1,1 y 1,7 por ciento), mientras que las tipo IIB y III se asociaron a una mayor presencia de dificultades (51,3 por ciento y 71,4 por ciento respectivamente) y porcentaje de conversión (9,2 y 23,8 por ciento respectivamente). Conclusiones: esta clasificación constituye una herramienta útil en la correlación de hallazgos ecográficos y laparoscópicos en colecistitis crónica y aguda, ayudando al cirujano en la predicción de problemas quirúrgicos, complicaciones y riesgo de conversión a cirugía abierta, apoyando los resultados previamente publicados.

Ductal variations in the Calot's triangle seen on laparoscopic cholecystectomy

To describe the frequency and pattern of ductal variations seen in the Calot's triangle on laparoscopic cholecystectomy. Descriptive study. This study was conducted in the Surgical Unit 1, Fauji Foundation Hospital, Rawalpindi from December 13, 20008 to February 22, 2011. 200 patients with a diagnosis of biliary colic, cholelithiasis, acute cholecystitis, empyema gall bladder and mucocele gall bladder were included in this study. Patients with age less than 15 years were excluded. Careful dissection of the Calot's triangle was carried out. The anatomical variations of the cystic duct and other anomalous variations in the region were noted and data analyzed on SPSS 10. The age range was 19 to 88 years with a mean of 48 years. The majority [88%] of the patients presented with a clinical diagnosis of biliary colic. The cystic duct was of normal size in 88%, short in 7%, and long in 5% of the cases. The cystic duct terminated laterally into the common hepatic duct in 94% of the cases, anteriorly into the common hepatic duct in 5% and posteriorly into the common hepatic duct in 1% of the cases. Each Calot's triangle differs from the other. Ductal variations are the hallmark of this region and their knowledge is mandatory for a safe laparoscopic cholecystectomy
