LIVER TRANSPLANTATION IN PATIENTS WITH PRIMARY SCLEROSING CHOLANGITIS: A MULTICENTRIC STUDY.

BACKGROUND: The prevalence of primary sclerosing cholangitis (PSC) in the general population has not yet been clearly established. The management of PSC should focus on delaying the progression of the disease and restraining its complications. The only curative therapy for the disease remains liver transplantation (LT). PSC is currently the fifth most common indication for LT and corresponds to 5% of all LT indications in adults. AIMS: Our objective is to evaluate the indications and outcomes of PSC patients undergoing LT in three liver transplantation centers in southern Brazil - Hospital Santa Isabel in Blumenau, Santa Catarina state, and Hospital das Clínicas and Hospital Nossa Senhora das Graças, in Curitiba, Parana state). METHODS: This is a longitudinal observational study of patients with PSC who underwent LT in three major Brazilian medical centers. Electronic medical records and study protocols of all patients subjected to LT from January 2011 to December 2021 were retrospectively reviewed. RESULTS: Of the 1,362 transplants performed in the three medical centers, 37 were due to PSC. Recurrence of PSC occurred in three patients (8.1%) in 3.0±2.4 years (range, 1-4 years). The 1-year and 5-year survival rates after the first LT were 83.8 and 80.6%, respectively. The 1-year and 5-year graft survival rates were, respectively, 83.8 and 74.8%. CONCLUSIONS: Our experience with LT in patients with PSC demonstrated good patient and graft survival results. Most deaths were due to common factors in patients undergoing LT.

ACUTE CHOLECYSTITIS IN HIGH-RISK PATIENTS. SURGICAL, RADIOLOGICAL, OR ENDOSCOPIC TREATMENT? BRAZILIAN COLLEGE OF DIGESTIVE SURGERY POSITION PAPER.

Acute cholecystitis (AC) is an acute inflammatory process of the gallbladder that may be associated with potentially severe complications, such as empyema, gangrene, perforation of the gallbladder, and sepsis. The gold standard treatment for AC is laparoscopic cholecystectomy. However, for a small group of AC patients, the risk of laparoscopic cholecystectomy can be very high, mainly in the elderly with associated severe diseases. In these critically ill patients, percutaneous cholecystostomy or endoscopic ultrasound gallbladder drainage may be a temporary therapeutic option, a bridge to cholecystectomy. The objective of this Brazilian College of Digestive Surgery Position Paper is to present new advances in AC treatment in high-risk surgical patients to help surgeons, endoscopists, and physicians select the best treatment for their patients. The effectiveness, safety, advantages, disadvantages, and outcomes of each procedure are discussed. The main conclusions are: a) AC patients with elevated surgical risk must be preferably treated in tertiary hospitals where surgical, radiological, and endoscopic expertise and resources are available; b) The optimal treatment modality for high-surgical-risk patients should be individualized based on clinical conditions and available expertise; c) Laparoscopic cholecystectomy remains an excellent option of treatment, mainly in hospitals in which percutaneous or endoscopic gallbladder drainage is not available; d) Percutaneous cholecystostomy and endoscopic gallbladder drainage should be performed only in well-equipped hospitals with experienced interventional radiologist and/or endoscopist; e) Cholecystostomy catheter should be removed after resolution of AC. However, in patients who have no clinical condition to undergo cholecystectomy, the catheter may be maintained for a prolonged period or even definitively; f) If the cholecystostomy catheter is maintained for a long period of time several complications may occur, such as bleeding, bile leakage, obstruction, pain at the insertion site, accidental removal of the catheter, and recurrent AC; g) The ideal waiting time between cholecystostomy and cholecystectomy has not yet been established and ranges from immediately after clinical improvement to months. h) Long waiting periods between cholecystostomy and cholecystectomy may be associated with new episodes of acute cholecystitis, multiple hospital readmissions, and increased costs. Finally, when selecting the best treatment option other aspects should also be considered, such as costs, procedures available at the medical center, and the patient's desire. The patient and his family should be fully informed about all treatment options, so they can help making the final decision.

Encapsulating peritoneal sclerosis post liver transplant and peritoneal dialysis: case report and literature review.

Encapsulating peritoneal sclerosis (EPS) is a rare and debilitating condition. A fibrocollagenous membrane, which promotes encasement of the small intestine leaving a cocoon-like appearance, takes place. It is mainly associated with peritoneal infections, medications, peritoneal dialysis and systemic inflammatory diseases. Diagnosis is based on clinical history, intestinal obstruction and imaging exam. We report a case of EPS in a 68-year-old man with a medical history of liver transplantation and peritoneal dialysis, complaining of obstructive bowel symptoms.

Neoplasia cística mucinosa do pâncreas / Mucinous cystic neoplasia of the pancreas

Introdução: Neoplasia cística mucinosa é tumor mucinoso benigno (cistoadenoma mucinoso) ou maligno (cistoadenocarcinoma mucinoso), que não se comunica com os ductos pancreáticos. Objetivo: Apresentar revisão da literatura sobre o tema. Método: Ênfase nas diretrizes das principais sociedades médicas mundiais na orientação do diagnóstico, tratamento e a vigilância da neoplasia cística mucinosa. Resultado: A quase totalidade dessas neoplasias ocorre no gênero feminino de 40-50 anos de idade. Como raras exceções, esta neoplasia é encontrada na cauda/corpo do pâncreas. Para estabelecer o diagnóstico é necessário a presença de estroma similar ao do ovário na parede do cisto no exame patológico. Exames de imagem de alta resolução, como tomografia, ressonância magnética e ecoendoscopia apresentam elevada precisão para identificar esta neoplasia. O tratamento cirúrgico consiste na pancreatectomia distal com linfadenectomia e esplenectomia. A via laparoscópica ou robótica é preferida para tumores <5-7 cm. Devido a possibilidade de rotura do tumor e disseminação da neoplasia, as lesões >5-7 cm devem ser submetidos à ressecção laparotômica. Conclusão: Não existe uniformidade internacional na conduta terapêutica. O tratamento cirúrgico deve ser indicado para todos os pacientes com condições cirúrgicas e que apresentam neoplasia ≥3-4 cm, dependendo do consenso.

Introduction: Mucinous cystic neoplasia is a benign mucinous tumor (mucinous cystadenoma) or malignant (mucinous cystadenocarcinoma), which does not communicate with the pancreatic ducts. Objective: To present a review of the literature on the topic. Method: Emphasis on the guidelines of the main global medical societies in guiding the diagnosis, treatment and surveillance of mucinous cystic neoplasia. Result: Almost all of these neoplasms occur in females aged 40-50 years. As a rare exception, this neoplasm is found in the tail/body of the pancreas. To establish the diagnosis, the presence of stroma similar to that of the ovary in the cyst wall is necessary on pathological examination. High-resolution imaging exams, such as tomography, magnetic resonance imaging and endoscopic ultrasound, are highly accurate in identifying this neoplasm. Surgical treatment consists of distal pancreatectomy with lymphadenectomy and splenectomy. The laparoscopic or robotic route is preferred for tumors <5-7 cm. Due to the possibility of tumor rupture and dissemination of the neoplasm, lesions >5-7 cm must undergo laparotomic resection. Conclusion: There is no international uniformity in therapeutic conduct. Surgical treatment should be indicated for all patients with surgical conditions and who have neoplasia ≥3-4 cm, depending on the consensus.

Acute cholecystitis in high-risk patients. surgical, radiological, or endoscopic treatment? brazilian college of digestive surgery position paper / Colecistite aguda em pacientes de alto risco. tratamento cirúrgico, radiológico ou endoscópico? posicionamento do colégio brasileiro de cirurgia digestiva

RESUMO A colecistite aguda (CA) é um processo inflamatório agudo da vesícula biliar que pode estar associado a complicações potencialmente graves, como empiema, gangrena, perfuração da vesícula biliar e sepse. O tratamento padrão para a CA é a colecistectomia laparoscópica. No entanto, para um pequeno grupo de pacientes com CA, o risco de colecistectomia laparoscópica pode ser muito alto, principalmente em idosos com doenças graves associadas. Nestes pacientes críticos, a colecistectomia percutânea ou a drenagem endoscópica da vesícula biliar guiada por ultrassom podem ser uma opção terapêutica temporária, como ponte para a colecistectomia. O objetivo deste artigo de posicionamento do Colégio Brasileiro de Cirurgia Digestiva é apresentar novos avanços no tratamento da CA em pacientes cirúrgicos de alto risco, para auxiliar cirurgiões, endoscopistas e clínicos a selecionar o melhor tratamento para os seus pacientes. A eficácia, segurança, vantagens, desvantagens e resultados de cada procedimento são discutidos. As principais conclusões são: a) Pacientes com CA e risco cirúrgico elevado devem ser tratados preferencialmente em hospitais terciários onde a experiência e os recursos cirúrgicos, radiológicos e endoscópicos estão disponíveis. b) A modalidade de tratamento ideal para pacientes com elevado risco cirúrgico, deve ser individualizada, com base nas condições clínicas e na experiência disponível. c) A colecistectomia laparoscópica continua sendo uma excelente opção de tratamento, principalmente em hospitais em que a drenagem da vesícula biliar percutânea ou endoscópica não está disponível. d) A colecistostomia percutânea e a drenagem endoscópica da vesícula biliar devem ser realizadas apenas em hospitais bem equipados e com radiologista intervencionista e/ou endoscopista experientes. e) O cateter de colecistostomia deve ser removido após a resolução da CA. No entanto, em pacientes que não têm condição clínica para realizar colecistectomia, o cateter pode ser mantido por um período prolongado ou mesmo definitivamente. f) Se o cateter de colecistostomia for mantido por longo período de tempo podem ocorrer várias complicações, como sangramento, fístula biliar, obstrução, dor no local de inserção, remoção acidental do cateter e CA recorrente. g) O tempo de espera ideal entre a colecistostomia e a colecistectomia ainda não foi estabelecido, e vai desde imediatamente após a melhoria clínica, até meses após. h) Longos períodos de espera entre colecistostomia e colecistectomia podem estar associados a novos episódios de CA, múltiplas readmissões hospitalares e aumento dos custos. Finalmente, ao selecionar a melhor opção de tratamento, outros aspectos também devem ser considerados, como custos, disponibilidade dos procedimentos no centro médico e o desejo do paciente. O paciente e sua família devem ser completamente informados sobre todas as opções de tratamento, para que possam ajudar a tomar a decisão final.

Liver transplantation in patients with primary sclerosing cholangitis: a multicentric study / Transplante hepático em pacientes com colangite esclerosante primária: estudo multicêntrico

ABSTRACT BACKGROUND: The prevalence of primary sclerosing cholangitis (PSC) in the general population has not yet been clearly established. The management of PSC should focus on delaying the progression of the disease and restraining its complications. The only curative therapy for the disease remains liver transplantation (LT). PSC is currently the fifth most common indication for LT and corresponds to 5% of all LT indications in adults. AIMS: Our objective is to evaluate the indications and outcomes of PSC patients undergoing LT in three liver transplantation centers in southern Brazil - Hospital Santa Isabel in Blumenau, Santa Catarina state, and Hospital das Clínicas and Hospital Nossa Senhora das Graças, in Curitiba, Parana state). METHODS: This is a longitudinal observational study of patients with PSC who underwent LT in three major Brazilian medical centers. Electronic medical records and study protocols of all patients subjected to LT from January 2011 to December 2021 were retrospectively reviewed. RESULTS: Of the 1,362 transplants performed in the three medical centers, 37 were due to PSC. Recurrence of PSC occurred in three patients (8.1%) in 3.0±2.4 years (range, 1-4 years). The 1-year and 5-year survival rates after the first LT were 83.8 and 80.6%, respectively. The 1-year and 5-year graft survival rates were, respectively, 83.8 and 74.8%. CONCLUSIONS: Our experience with LT in patients with PSC demonstrated good patient and graft survival results. Most deaths were due to common factors in patients undergoing LT.

RESUMO RACIONAL: A prevalência de colangite esclerosante primária (CEP) na população em geral ainda não foi claramente estabelecida. O manejo da CEP deve se concentrar em retardar a progressão da doença e gerenciar suas complicações. A única terapia curativa para a doença continua sendo o transplante hepático (TH). A CEP é atualmente a 5ª indicação mais comum de TH e corresponde a 5% de todas as indicações de TH em adultos OBJETIVOS: O nosso objetivo é avaliar as indicações e os resultados do transplante de fígado em pacientes com CEP submetidos a TH em três centros de transplante de fígado no sul do Brasil (Hospital Santa Isabel, Blumenau, Santa Catarina; Hospital das Clínicas, Curitiba, Paraná; e Hospital Nossa Senhora das Graças, Curitiba, Paraná). MÉTODOS: Este é um estudo observacional longitudinal de pacientes com colangite esclerosante primária que foram submetidos a transplante hepático em três grandes centros médicos brasileiros. Os prontuários eletrônicos de todos os pacientes submetidos a TH de Janeiro de 2011 a Dezembro de 2021, foram avaliados retrospectivamente. RESULTADOS: De um total de 1.362 transplantes realizados nos três centros médicos, 37 eram devidos à CEP. A recorrência de CEP ocorreu em 3 pacientes (8,1%) em 3±2,4 anos (intervalo, 1-4 anos). A taxa de sobrevida de 1 ano e 5 anos após o 1° TH foi respectivamente de 83,8 e 80,6%. As taxas de sobrevida dos enxertos em 1 ano e 5 anos foram, respectivamente, 83,8 e 74,8%. CONCLUSÕES: A nossa experiência com TH em pacientes com CEP demonstrou bons resultados de sobrevida dos pacientes e dos enxertos. A maioria dos óbitos ocorreu devido a fatores comuns em pacientes submetidos a TH.

INDICATION FOR LIVER TRANSPLANTATION DUE TO HEPATOCELLULAR CARCINOMA: ANALYSIS OF 1,706 PROCEDURES OVER THE PAST DECADE IN THE STATE OF PARANÁ.

BACKGROUND: Patients listed for liver transplantation and hepatocellular carcinoma are considered priority on the waiting list, and this could overly favor them. AIM: This study aimed to evaluate the impact of this prioritization. METHODS: We analyzed the liver transplants performed in adults from 2011 to 2020 and divided into three groups: adjusted Model of End-Stage Liver Disease (MELD) score for hepatocellular carcinoma, other adjusted Model of End-Stage Liver Disease situations, and no adjusted Model of End-Stage Liver Disease. RESULTS: A total of 1,706 patients were included in the study, of which 70.2% were male. Alcoholism was the main etiology of cirrhosis (29.6%). Of the total, 305 patients were with hepatocellular carcinoma, 86 with other adjusted Model of End-Stage Liver Disease situations, and 1,315 with no adjusted Model of End-Stage Liver Disease. Patients with hepatocellular carcinoma were older (58.9 vs. 53.5 years). The predominant etiology of cirrhosis was viral hepatitis (60%). The findings showed that group with adjusted Model of End-Stage Liver Disease had lower physiological Model of End-Stage Liver Disease (10.9), higher adjusted Model of End-Stage Liver Disease (22.6), and longer waiting list time (131 vs. 110 days), as compared to the group with no adjusted Model of End-Stage Liver Disease. The total number of transplants and the proportion of patients transplanted for hepatocellular carcinoma increased from 2011 to 2020. There was a reduction in the proportion of patients with hepatocellular carcinoma and adjusted Model of End-Stage Liver Disease of 20 and there was an increase on waiting list time in this group. There was an increase in the proportion of those with adjusted Model of End-Stage Liver Disease of 24 and 29, but the waiting list time remained stable. CONCLUSION: Over the past decade, prioritization of hepatocellular carcinoma resulted in an increased proportion of transplanted patients in relation to those with no priority. It also increased waiting list time, requiring higher adjusted Model of End-Stage Liver Disease to transplant an organ.

Gallbladder agenesis a rare and underdiagnosed congenital anomaly: a case report and literature review.

Gallbladder agenesis (GA) is a rare congenital anomaly with conflicting epidemiology described in the literature. When present, it is misinterpreted as cholelitiasis, a highly prevalent condition. Nevertheless, surgeons and radiologists must be aware of it since it can lead to unnecessary invasive procedures. Diagnosis of GA is challenging due to the anatomical structures that sometimes resemble a shrunken gallbladder. We report the case of a 55-year-old man with preoperative diagnosis of cholelitiasis and further intraoperative find of GA. Since cholecystectomy is one of the most common surgeries worldwide, it demonstrates how relevant this case is to emphasize the need to recognize this diagnosis and be aware of its management to avoid unnecessary surgery.

Gastric adenocarcinoma in the excluded stomach 18 years after bariatric surgery: a case report.

Gastric cancer (GC) ranks fourth in overall cancer mortality. Bariatric surgical procedures, especially the gastric bypass surgery (GBS), raise a concern about the risk of GC in the excluded stomach (ES). Diagnosis of GC in the ES is challenging due to anatomical changes and impossibility of endoscopic access to the ES. There are few reports of GC after GBS, and it occurs more in the gastric stump than in the ES. We report a case of a 54-year-old female with GC in the ES 18 years after GBS. The increasing number of GBS and the aggressiveness of the GC show how relevant this case is to emphasize the need to consider this diagnosis in patients who develop upper abdominal symptoms, anemia or weight loss.

Septic Thrombophlebitis of the Internal Jugular Vein in an Immunocompromised Patient with Lemierre Syndrome: A Case Report.

Lemierre syndrome is a rare complication of oropharyngeal infection, especially acute pharyngotonsillitis, associated with septicemia and thrombophlebitis of the internal jugular vein (IJV). We present the case of a 52-year-old patient who underwent liver transplantation and returned with symptoms of pain, redness and left cervical bulging 1 month after surgery. After investigation, the diagnosis of septic thrombophlebitis of the IJV was made. The patient responded well to treatment with antibiotic therapy and full anticoagulation. To the best of our knowledge, the present report is the first report of Lemierre syndrome in a post-liver transplant patient.

Mesenteric venous thrombosis in a pregnant woman at first trimester gestation: a case report.

Mesenteric vein thrombosis (MVT) in a pregnant patient is a rare condition that seems to be associated with the pregnancy pró-thrombotic state. This can lead to severe circumstances such as intestinal hemorrhagic ischemia, sepsis, abortion and death. Abdominal assessment is challenging due to the anatomical and physiological changes during pregnancy. MVT clinical and complementary evaluation are nonspecific, making essential an image exam. We report a case of a 33-years-old woman at 11 weeks of gestation. She sought medical evaluation due to abdominal pain and had an appendicitis diagnosis, which was treated by laparoscopic surgery. One week later, she came back complaining of nonspecific abdominal pain. So an extensive evaluation was made, and the diagnosis of MVT and intestinal ischemia was concluded. She underwent laparotomy exploration and anticoagulation, having a good evolution and so was discharged on the sixth post-operative day.

Pneumatosis cystoides intestinalis with pneumoperitoneum in an 87-years-old male patient: a case report.

Pneumatosis cystoides intestinalis (PCI) is a rare condition, characterized by gas-filled cysts in the intestinal wall. The mesentery and intra-abdominal ligaments can be affected. PCI is classified as primary or secondary and associated with multiple predisposing factors. An asymptomatic 87-year-old man underwent an abdominal tomography for follow-up of bladder carcinoma. The examination revealed intestinal and mesenteric pneumatosis associated with pneumoperitoneum. At laparoscopy, intestinal and mesenteric pneumatosis without intestinal infarction was identified. He was discharged on the fifth postoperative day. PCI is a benign condition that can be confused with mesenteric ischemia. Treatment is conservative, with periodic clinical evaluations. Surgical procedure is unnecessary for its diagnosis or management.

Liver transplantation for the treatment of iatrogenic bile duct injury / Transplante hepático no tratamento da lesão iatrogênica da via biliar

ABSTRACT Objective: to assess the outcomes of our patients who were subjected to LT for iatrogenic bile duct injury. Methods: all patients who underwent LT for treatment of complications of biliary duct injury were included in the study. Medical records and study protocols of these patients were retrospectively analyzed to determine demographic and clinical characteristics, treatment, and outcome of the patients. Results: of a total of 846 liver transplants performed, 12 (1.4%) were due to iatrogenic bile duct injury: 10 (83.3%) occurred during cholecystectomy, 1 (8.3%) following chemoembolization, and 1 (8.3%) during laparotomy to control abdominal bleeding. Cholecystectomy was performed by open access in 8 patients and by laparoscopic access in two . There were 8 female (66.7%) and 4 male (33.3%) with a mean age of 50.6 ± 13.1 years (range 23 to 70 years). All transplants were performed with livers from cadaveric donors. The mean operative time was 558.2 ± 105.2 minutes (range, 400-782 minutes). Biliary reconstruction was performed with Roux-en-Y hepaticojejunostomy in 11 patients and choledochocholedochostomy in one. Seven patients died (58.3%) and five (41.7%) were alive during a mean followed up of 100 months (range 18 to 118 months). Conclusion: liver transplantation in patients with iatrogenic bile duct injury is a complex procedure with elevated morbimortality.

RESUMO Objetivo: avaliar os resultados dos nossos pacientes que foram submetidos a transplante hepático por lesão iatrogênica do ducto biliar. Métodos: todos os pacientes que foram submetidos a transplante hepático para tratamento de complicações da lesão do ducto biliar foram incluídos no estudo. Os prontuários e protocolos de estudo desses pacientes foram analisados retrospectivamente para determinar características demográficas e clínicas, tratamento e desfecho dos pacientes. Resultados: de um total de 846 transplantes hepáticos realizados, 12 (1,4%) foram por lesão iatrogênica de via biliar: 10 (83,3%) ocorreram durante colecistectomia, 1 (8,3%) após quimioembolização e 1 (8,3%) durante laparotomia para controle de sangramento abdominal. A colecistectomia foi realizada por via aberta em 8 pacientes e por via laparoscópica em dois. Haviam 8 mulheres (66,7%) e 4 homens (33,3%), com média de idade de 50,6 ± 13,1 anos (variação de 23 a 70 anos). Todos os transplantes foram realizados com fígados de doadores cadavéricos. O tempo operatório médio foi de 565,2 ± 106,2 minutos (variação de 400-782 minutos). A reconstrução biliar foi realizada com hepaticojejunostomia em Y de Roux em 11 pacientes e coledococoledocostomia em um. Sete pacientes morreram (58,3%) e cinco (41,7%) estavam vivos durante um seguimento médio de 100 meses (variação de 18 a 118 meses). Conclusão: o transplante hepático em pacientes com lesão iatrogênica das vias biliares é um procedimento complexo com elevada morbimortalidade.

Indication for liver transplantation due to hepatocellular carcinoma: analysis of 1,706 procedures over the past decade in the state of paraná / Indicação de transplante hepático por hepatocarcinoma: análise de 1.706 procedimentos na última década no estado do paraná

ABSTRACT BACKGROUND: Patients listed for liver transplantation and hepatocellular carcinoma are considered priority on the waiting list, and this could overly favor them. AIM: This study aimed to evaluate the impact of this prioritization. METHODS: We analyzed the liver transplants performed in adults from 2011 to 2020 and divided into three groups: adjusted Model of End-Stage Liver Disease (MELD) score for hepatocellular carcinoma, other adjusted Model of End-Stage Liver Disease situations, and no adjusted Model of End-Stage Liver Disease. RESULTS: A total of 1,706 patients were included in the study, of which 70.2% were male. Alcoholism was the main etiology of cirrhosis (29.6%). Of the total, 305 patients were with hepatocellular carcinoma, 86 with other adjusted Model of End-Stage Liver Disease situations, and 1,315 with no adjusted Model of End-Stage Liver Disease. Patients with hepatocellular carcinoma were older (58.9 vs. 53.5 years). The predominant etiology of cirrhosis was viral hepatitis (60%). The findings showed that group with adjusted Model of End-Stage Liver Disease had lower physiological Model of End-Stage Liver Disease (10.9), higher adjusted Model of End-Stage Liver Disease (22.6), and longer waiting list time (131 vs. 110 days), as compared to the group with no adjusted Model of End-Stage Liver Disease. The total number of transplants and the proportion of patients transplanted for hepatocellular carcinoma increased from 2011 to 2020. There was a reduction in the proportion of patients with hepatocellular carcinoma and adjusted Model of End-Stage Liver Disease of 20 and there was an increase on waiting list time in this group. There was an increase in the proportion of those with adjusted Model of End-Stage Liver Disease of 24 and 29, but the waiting list time remained stable. CONCLUSION: Over the past decade, prioritization of hepatocellular carcinoma resulted in an increased proportion of transplanted patients in relation to those with no priority. It also increased waiting list time, requiring higher adjusted Model of End-Stage Liver Disease to transplant an organ.

RESUMO RACIONAL: Pacientes portadores de carcinoma hepatocelular com indicação de transplante hepático recebem prioridade na lista de espera e isso poderia favorecê-los demasiadamente. OBJETIVO: Avaliar o impacto dessa priorização. MÉTODOS: Foram analisados os transplantes hepáticos realizados de 2011 até 2020 no estado do Paraná, divididos em três grupos: portadores de carcinoma hepatocelular no modelo para doença hepática terminal (MELD) ajustado, outras situações no modelo para doença hepática terminal ajustado e sem o modelo para doença hepática terminal ajustado. RESULTADOS: Foram incluídos 1.706 pacientes, 70,2% do gênero masculino, a maioria portadores de cirrose alcoólica (29,6%): 305 com hepatocarcinoma, 86 com outras situações no modelo para doença hepática terminal ajustado e 1.315 sem o modelo para doença hepática terminal ajustado. Nos portadores de hepatocarcinoma, a idade média foi maior (58,9 vs 53,5 anos), a etiologia predominante da cirrose foram as hepatites virais (60%), apresentaram menor no modelo para doença hepática terminal fisiológico (10,9), maior no modelo para doença hepática terminal corrigido (22,6 vs 21,8) e maior tempo em lista de espera (131 vs 110 dias) quando comparados ao grupo sem o modelo para doença hepática terminal ajustado. O número de transplantes e a proporção de pacientes transplantados por hepatocarcinoma aumentou de 2011 até 2020. Houve redução da proporção dos portadores de hepatocarcinoma com o modelo para doença hepática terminal de 20 no decorrer da década e aumento do tempo em lista nesse grupo. Para os com modelo para doença hepática terminalde 24 e de 29, houve aumento na proporção e o tempo em lista permaneceu estável. CONCLUSÃO: A priorização do hepatocarcinoma conferiu maior modelo para doença hepática terminal e incremento na proporção de transplantes em relação aos sem prioridade. Também aumentou o tempo em lista de espera, necessitando maior modelo para doença hepática terminal corrigido para obtenção de um órgão.

Management of pneumatosis cystoides intestinalis with pneumoperitoneum: 5-years systematic review

Introduction: Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by gas-filled cysts in the intestinal wall. Although rare, it may also involve other regions, such as the mesentery. PCI is classified as primary or secondary and is associated with multiple predisposing factors. It may be associated with either a benign condition or a potentially fatal condition, such as mesenteric ischemia. The objective of this study was to review the medical literature on the rare benign presentations of PCI, excluding cases associated with intestinal ischemia.Methods: We conducted a systematic literature review according to the PRISMA statement. We searched PubMed and LILACS databases for articles published between January 2015 and December 2020 using the following Medical Subject Headings: "pneumatosis cystoides intestinalis" and "pneumoperitoneum," "pneumatosis intestinalis," and "pneumoperitoneum" or "mesenteric pneumatosis."Results: We included 51 articles comprising 58 patients with PCI and pneumoperitoneum. Most patients were men, and mean patient age was 64.9 years. We identified an idiopathic etiology in 29.31% of cases, and the most common predisposing factor was immune dysfunction (29.31%). A total of 24.13% of patients were asymptomatic. The most commons symptoms were abdominal pain (43.10%), nausea and vomiting (41.37%), and abdominal distention (37.93%). Diagnostic surgery was conducted in 26 patients (44.82%). Only 1 patient underwent surgical treatment.Conclusions: PCI is a clinical condition that may have a benign etiology and not require surgery. Treatment of the benign etiology is conservative. Thus, life-threatening conditions should be excluded in all cases.

Retroperitoneal fetus in fetu in a 65-year-old man

Fetus in fetu (FIF) is a rare congenital anomaly in which a malformed fetus is incorporated within the body of its twin. It was first described in the late 18th century and has an incidence of 1:500,000 live births. In most cases, the diagnosis is made in infants or young adults. To date, the oldest patient reported in the literature was 47 years old. We describe the case of a 65-year-old patient with FIF, now the oldest reported in the literature. Our patient meets all the diagnostic criteria for FIF, including the presence of a limb in advanced formation inside the lesion. The treatment was surgical excision. FIF should be considered in the differential diagnosis of abdominal masses, typically recognized in infancy. Symptoms arise from mass effects. Surgical resection should be performed due to the potential for malignant transformation.

Biliary tract melanoma metastasis mimicking hilar cholangiocarcinoma: a case report.

Malignant melanoma is the 19th leading cause of cancer worldwide. It is an aggressive neoplastic disease in which pathophysiological understanding and management has been in constant evolution in recent decades. The primary site is the skin, uvea and mucous membranes and has the capacity to metastasize to any organ. There are few reports of primary or secondary involvement of the biliary tract. We present the case of a 73-year-old woman with a bile duct lesion suggestive of cholangiocarcinoma and a final diagnosis of a single melanoma metastasis. Surgical treatment was performed due to oligometastatic stage IV melanoma with possibility of R0 resection followed by immune checkpoint therapy.

SIMULTANEOUS LAPAROSCOPIC INGUINAL HERNIA REPAIR AND CHOLECYSTECTOMY: DOES IT CAUSE MESH INFECTION?

BACKGROUND: Repair of inguinal hernia concomitant with cholecystectomy was rarely performed until more recently when laparoscopic herniorrhaphy gained more adepts. Although it is generally an attractive option for patients, simultaneous performance of both procedures has been questioned by the potential risk of complications related to mesh, mainly infection. AIM: To evaluate a series of patients who underwent simultaneous laparoscopic inguinal hernia repair and cholecystectomy, with emphasis on the risk of complications related to the mesh, especially infection. METHODS: Fifty patients underwent simultaneous inguinal repair and cholecystectomy, both by laparoscopy, of which 46 met the inclusion criteria of this study. RESULTS: In all, hernia repair was the first procedure performed. Forty-five (97,9%) were discharged within 24 h after surgery. Total mean cost of the two procedures performed separately ($2,562.45) was 43% higher than the mean cost of both operations done simultaneously ($1,785.11). Up to 30-day postoperative follow-up, seven (15.2%) presented minor complications. No patient required hospital re-admission, percutaneous drainage, antibiotic therapy or presented any other signs of mesh infection after three months. In long-term follow-up, mean of 47,1 months, 38 patients (82,6%) were revaluated. Three (7,8%) reported complications: hernia recurrence; chronic discomfort; reoperation due a non-reabsorbed seroma, one in each. However, none showed any mesh-related complication. Satisfaction questionnaire revealed that 36 (94,7%) were satisfied with the results of surgery. All of them stated that they would opt for simultaneous surgery again if necessary. CONCLUSION: Combined laparoscopic inguinal hernia repair and cholecystectomy is a safe procedure, with no increase in mesh infection. In addition, it has important advantage of reducing hospital costs and increase patient' satisfaction.

FEMORAL HERNIA: UNCOMMON, BUT ASSOCIATED WITH POTENTIALLY SEVERE COMPLICATIONS.

BACKGROUND: Although the laparoscopic access is becoming the preferable treatment for femoral hernia, there are only few studies on this important subject. AIM: To assess the outcomes of the totally extraperitoneal laparoscopic (TEP) access in the treatment of femoral hernia. METHODS: Data of 62 patients with femoral hernia who underwent herniorrhaphy were retrospectively reviewed. The diagnosis of femoral hernia was established by clinical and/or imaging exams in 55 patients and by laparoscopic findings in seven. RESULTS: There were 55 (88.7%) females and 7 (11.3%) males, with female to male ratio of 8:1. The mean age was of 58.9±15.9 years, ranging from 22 to 92 years. Most patients (n=53; 85.5%) had single hernia and the remaining (n=9; 14.5%) bilateral, making a total of 71 hernias operated. Prior lower abdominal operations were recorded in 21 (33.9%) patients. Conversion to laparoscopic transabdominal preperitoneal procedure was performed in four (6.5%). Open herniorrhaphy was needed in two (3.2%), one with spontaneous enterocutaneous fistula in the groin region (Richter's hernia) and the another with incidental perforation of the adjacent small bowel that occurred during dissection of hernia sac. There was no mortality. CONCLUSION: Femoral hernia is uncommon, and it may be associated with potentially severe complications. Most femoral hernias may be successfully treated with totally extraperitoneal laparoscopic access, with low conversion and complication rates.
