Síndrome de Mirizzi: estudo de 11 casos / Mirizzis syndrome: report of eleven cases

Objetivo: descrever série de onze pacientes com síndrome de Mirizzi, submetidos a tratamento cirúrgico, comentando os aspectos etiopatogênicos e apresentação clínica, com ênfase no diagnóstico e tratamento. Métodos: estudo retrospectivo de onze pacientes consecutivos submetidos a tratamento cirúrgico. Foram considerados para apreciação: aspectos demográfico, clínicos, laboratoriais, meios diagnósticos, achados intraoperatórios, classificação dos doentes de acordo com Csendes et al., tática cirúrgica empregada e evolução pós-operatória. Resultados: dez pacientes (91,0%) eram mulheres e um (9,0%) homem. Os seguintes sintomas foram observados: dor e icterícia em todos os pacientes, colúria em nove (81,0%), náuseas e vômitos em sete (63,0%), acolia fecal em cinco (45,0%) e tumor palpável em um (9,0%). Os exames de laboratório mostraram leucocitose igual ou superior a 15.000 /mm3 em 45,0%. A bilirrubina total variou de 3,1 a 19,0 mg/dl. A ultrassonografia feita em todos pacientes mostrou presença de colelitíase e dilatação de V.B. em 77,7% e vesícula escleroatrófica em 27,0%. A tomografia computadorizada abdominal foi realizada em 9,0% e colangiopancreatografia em 18,0%. Os casos foram classificados, segundo Csendes, em: tipo I (quatro), tipo II (dois), tipo III (três) e tipo IV (dois) pacientes. Todos foram operados por cirurgia convencional. Destes, quatro (36,0%) apresentavam colangite, sendo três (27,0%) operados na urgência e um outro evoluiu com colangite durante a investigação, sendo operado no 19 dia. Os demais foram internados e operados eletivamente. Realizou-se: colecistectomia e derivação biliodigestiva em seis pacientes (54,0%), colecistectomia e coledocotomia em três (27,0%) e colecistectomia simples em dois casos (18%). No pós-operatório, nove (82,0%) evoluíram bem e tiveram alta hospitalar. Dois pacientes (18,0%) foram a óbito. Conclusões: todos os pacientes apresentavam sinais e sintomas de icterícia obstrutiva e em quase metade o hemograma era infeccioso. Apenas em três casos houve suspeita diagnóstica no pré-operatório. Os pacientes estáveis, sem infecção, que permitiram melhor investigação evoluíram favoravelmente. O tratamento da síndrome de Mirizzi é cirúrgico, variando a tática de acordo com o tipo da lesão.

Objectives: to report a series of eleven patients with Mirizzis syndrome submitted to surgical treatment. The authors present the etiopathogenic and clinical aspects of the disease. Methods: retrospective study of the eleven patients consecutive submitted to surgical treatment. The authors analysed the demografic, clinical and laboratory data, as well as intraoperative findings. They also classified the lesion according to Csendes classification, and presented the surgical management and post-operative follow-up. Results: there were 10 female patients (91.0 %) and 1 male patient (9.0%). Symptoms and signs were diffuse upper abdominal pain and jaundice in all patients, choluria in 9 (81%), nausea and vomit in 7 (63%), fecal acholia in 5 (45.0%) and a palpable tumor in 1 patient (9.0%). The laboratory exams showed leucocytosis equal or superior to 15.000/mm³ (45%) and the plasma bilirrubin varied between 3.1 mg/dL and 19.0 mg/dL. Ultrasonography showed in all patients the presence of cholelithiasis. There was dilation of gallbladder in 77.5% of the cases and scleroatrophic gallbladder in 27.0% patients. CT scan was realized in 9.0% and cholangiopancreatography in 18% of patients. The cases were classified according to Csendes classification. There were four type I, two type II, three type III and two type IV. All eleven cases were managed by classical open technique. Four patients (36%) presented with cholangitis; three of these patients had emergency operations and one presented cholangitis during the workup investigation, being operated on day 19 of admission. The others had elective operations. The surgical operations were: cholecystectomy and biliodigestive deviation in 6 patients (54%), cholecystectomy and choledochotomy in 3 patients (27%) and only cholecystectomy in 2 patients (18%). The postoperative course was uneventful in 9 patients (82%), but 2 patients (18%) died. Conclusion: all patients presented symptoms and signs of obstructive jaundice, and nearly half of these had infectious hemogram. The diagnosis of Mirizzis syndrome was suspected in only three patients. A complete diagnostic investigation was possible only in stable patients without infection, and these patients had a favorable course. Treatment of Mirizzis syndrome is surgical and the choice of operative approach varies according to the type of lesion.

Randomized clinical trial comparing spinal anesthesia with local anesthesia with sedation for loop colostomy closure.

CONTEXT: Recent studies have shown that local anesthesia for loop colostomy closure is as safe as spinal anesthesia for this procedure. OBJECTIVES: Randomized clinical trial to compare the results from these two techniques. METHODS: Fifty patients were randomized for loop colostomy closure using spinal anesthesia (n = 25) and using local anesthesia (n = 25). Preoperatively, the bowel was evaluated by means of colonoscopy, and bowel preparation was performed with 10% oral mannitol solution and physiological saline solution for lavage through the distal colostomy orifice. All patients were given prophylactic antibiotics (cefoxitin). Pain, analgesia, reestablishment of peristaltism or peristalsis, diet reintroduction, length of hospitalization and rehospitalization were analyzed postoperatively. RESULTS: Surgery duration and local complications were greater in the spinal anesthesia group. Conversion to general anesthesia occurred only with spinal anesthesia. There was no difference in intraoperative pain between the groups, but postoperative pain, reestablishment of peristaltism or peristalsis, diet reintroduction and length of hospitalization were lower with local anesthesia. CONCLUSIONS: Local anesthesia plus sedation offers a safer and more effective method than spinal anesthesia for loop colostomy closure.

CONTEXTO: Estudos recentes têm demonstrado que a anestesia local para o fechamento de colostomia em alça é tão segura quanto a raquianestesia para estes procedimentos. OBJETIVOS: Comparar os resultados do fechamento de colostomia em alça usando essas duas técnicas. MÉTODOS: Cinquenta pacientes foram randomizados para o fechamento de colostomia em alça sob raquianestesia (n = 25) e anestesia local (n = 25). No pré-operatório, o cólon foi avaliado por colonoscopia e o preparo intestinal foi realizado com solução oral de manitol a 10 por cento e limpeza com solução salina fisiológica através do orifício distal da colostomia. Todos os pacientes receberam antibioticoprofilaxia com cefoxitina. Dor, analgesia, restabelecimento do peristaltismo, reintrodução da dieta, tempo de internação e de reinternação foram analisados no pós-operatório. RESULTADOS: Duração da cirurgia e complicações locais foram maiores no grupo da raquianestesia. A conversão para anestesia geral ocorreu somente no grupo da raquianestesia. Em relação á dor intraoperatória, não houve diferença entre os grupos, mas a dor pós-operatória, restabelecimento do peristaltismo, reintrodução da dieta e tempo de hospitalização foram menores no grupo com anestesia local. CONCLUSÃO: A anestesia local associada à sedação ofereceu um método mais seguro e efetivo que a raquianestesia para o fechamento de colostomia em alça.

Cost-effectiveness analysis on spinal anesthesia versus local anesthesia plus sedation for loop colostomy closure.

CONTEXT: Studies in the area of health economics are still poorly explored and it is known that the cost savings in this area is becoming more necessary, provided that strict criteria. OBJECTIVE: To perform a cost-effectiveness analysis of spinal anesthesia versus local anesthesia plus sedation for loop colostomy closure. METHODS: This was a randomized clinical trial with 50 patients undergoing loop colostomy closure either under spinal anesthesia (n = 25) or under local anesthesia plus sedation (n = 25). The duration of the operation, time spent in the post-anesthesia recovery room, pain, postoperative complications, length of hospital stay, laboratory and imaging examinations and need for rehospitalization and reoperation were analyzed. The direct medical costs were analyzed. A decision tree model was constructed. The outcome measures were mean cost and cost per local and systemic postoperative complications avoided. Incremental cost-effectiveness ratios were presented. RESULTS: Duration of operation: 146 +/- 111.5 min. vs 105 +/- 23.6 min. (P = 0.012); mean time spent in post-anesthesia recovery room: 145 +/- 110.8 min. vs 36.8 +/- 34.6 min. (P<0.001). Immediate postoperative pain was lower with local anesthesia plus sedation (P<0.05). Local and systemic complications were fewer with local anesthesia plus sedation (P = 0.209). Hospitalization + rehospitalization: 4.5 +/- 4.1 days vs 2.9 +/- 2.2 days (P<0.0001); mean spending per patient: R$ 5,038.05 vs 2,665.57 (P<0.001). Incremental cost-effectiveness ratio: R$ -474.78, indicating that the strategy with local anesthesia plus sedation is cost saving. CONCLUSION: In the present investigation, loop colostomy closure under local anesthesia plus sedation was effective and appeared to be a dominant strategy, compared with the same surgical procedure under spinal anesthesia.

OBJETIVO: Análise de custo-efetividade entre fechamento de colostomia e m alça sob raquianestesia versus anestesia local associada à sedação. MÉTODOS: Ensaio clínico randomizado com 50 pacientes para fechamento de colostomia em alça, sob raquianestesia (n = 25) e sob anestesia local com sedação (n = 25). Avaliaram-se tempo operatório e de sala de recuperação pós-anestésica, dor, complicações pós-operatórias, tempo de internação, exames laboratoriais e de imagens, reoperações e reinternações. Foi feita análise de custos diretos médicos. A medida de desfecho foi: complicações pós-operatórias locais e sistêmicas. Aplicaram-se razão incremental e árvore de decisão. RESULTADOS: Tempo operatório (146 ± 111,5 min vs 105 ± 23,6 min; P = 0,012), tempo médio de sala de recuperação pós-anestésica (145 ± 110,8 min vs 36,8 ± 34,6 min, P<0,001). Dor no pós-operatório imediato em favor da anestesia local (P<0,05). Complicações pós-operatórias locais e sistêmicas (P = 0,209) em favor da anestesia local. Internação + reinternações (4,5 ± 4,1 dias vs 2,9 ± 2,2 dias; P<0,0001), valor médio gasto por paciente (R$ 5.038,05 vs R$ 2.665,57; P<0,001). Razão de custo-efetividade: -R$ 474,78, indicando que a estratégia é dominante. CONCLUSÃO: Na presente investigação o fechamento de colostomia em alça sob anestesia local associada à sedação foi eficaz e apresentou boa relação de custo-efetividade em relação ao mesmo procedimento cirúrgico sob raquianestesia.

Hérnia de spiegel: relato de quatro casos / Spigelian hernia: report of four cases

Racional: A hérnia de Spiegel é uma entidade pouco reconhecida e não propriamente rara, correspondendo a menos de 1% das hérnias de parede abdominal. Nosso objetivo é o de relatar quatro casos e abordar os diversos aspectos anatômicos e clínicos que corroboram para sua dificuldade diagnóstica. Relato dos casos: Quatro pacientes do sexo feminino, que apresentaram dor e desconforto abdominal na região pararretal, logo abaixo da cicatriz umbilical, acompanhados de massas abdominais palpáveis. A suspeição clínica de hérnia de Spiegel foi confirmada por métodos de imagens: USG e TC de abdome. Foram operadas em caráter eletivo, por cirurgia convencional e com utilização de prótese de polipropileno em dois casos. Apresentaram boa evolução pós-operatória e mantêm-se assintomáticas no seguimento ambulatorial. Conclusão: A hérnia de Spiegel apresenta sinais e sintomas poucos específicos e deve ser sempre lembrada em casos de dor / desconforto e abaulamento em parede ântero-Iateral do abdome...

[Transmural endoscopy drainage of pancreatic pseudocyst: long-term outcome]. / Drenagem endoscópica transmural de pseudocisto pancreático: resultados a longo prazo.

BACKGROUND: Pancreatic pseudocysts are relatively common complications of pancreatitis in adults. OBJECTIVE: To evaluate the long-term results from transmural endoscopic drainage and thus to establish its role in managing pancreatic pseudocyst. METHODS: Fourteen patients with pancreatic pseudocyst were studied. Their main complaint was pain in the upper levels of the abdomen. They presented palpable abdominal mass and underwent cystogastrostomy (n = 12) and cystoduodenostomy (n = 2), with clinical follow-up using abdominal computed tomography for up to 51 months. Retrograde endoscopic cholangiopancreatography was attempted in all cases to study the pancreatic duct and classify the cysts. RESULTS: There were 10 cases (71.5%) of chronic pancreatitis that had become acute through alcohol abuse and 4 (28.5%) that had become acute through biliary disorders. Both types of endoscopic drainage (cystogastrostomy and cystoduodenostomy) were effective. There was no change in the therapeutic management proposed. Migration of the orthesis into the pseudocyst at the time of insertion (two cases) was the principal complication, and these could be removed during the same operation, by means of a Dormia basket, with the aid of fluoroscopy. There has so far not been any mortality or relapse. The mean hospital stay was 3 days. CONCLUSION: Transmural endoscopic drainage was an efficacious form of therapy, presenting a low complication rate and no mortality, and only requiring a short stay in hospital.

Drenagem endoscópica transmural de pseudocisto pancreático: resultados a longo prazo / Transmural endoscopy drainage of pancreatic pseudocyst: long-term outcome

RACIONAL: Os pseudocistos pancreáticos são complicações relativamente comuns em pacientes adultos com pancreatite. OBJETIVO: Avaliar os resultados a longo prazo da drenagem endoscópica transmural, estabelecendo seu papel no manejo do pseudocisto pancreático. MÉTODOS: Foram estudados 14 pacientes com pseudocisto de pâncreas, cuja principal queixa à apresentação foi dor no andar superior do abdome e massa abdominal palpável, submetidos a cistogastrostomia (n = 12) e cistoduodenostomia (n = 2), acompanhados clinicamente e com tomografia computadorizada de abdome por até 51 meses. A colangiopancreatografia endoscópica retrógrada era tentada em todos os casos para estudo do ducto pancreático e classificação dos cistos. RESULTADOS: A pancreatite crônica alcoólica agudizada foi responsável por 10 casos (71,5 por cento) e a biliar por 4 (28,5 por cento). As duas formas de drenagens (cistogastrostomia e cistoduodenostomia) endoscópicas foram efetivas. Não houve mudança na conduta terapêutica proposta; em dois pacientes a migração da órtese para o interior do pseudocisto, no momento da inserção, foi a principal complicação, sendo possível sua retirada no mesmo ato, com o uso da cesta de Dormia, sob o auxílio de fluoroscopia. Não houve mortalidade, nem recidiva até o momento. O tempo médio de permanência hospitalar foi de 3 dias. CONCLUSÃO: A drenagem endoscópica transmural se apresentou como terapêutica eficaz, com baixo índice de complicações, mortalidade nula e pequeno tempo de internação hospitalar.
