Bile duct hamartomas--the von Meyenburg complex.

Hamartomas of the bile duct (von Meyenburg complex) are benign neoplasms of the liver, constituted histologically cystic dilatations of the bile duct, encompassed by fibrous stroma. We report a 42-year-old female patient with symptomatic cholecystitis, whose gross and ultrasonic appearance suggestive of multiple liver metastases. Magnetic resonance imaging and liver biopsy are the gold standards for diagnosis of this rare hepatobiliary condition.

[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.

Neuroendocrine gastric carcinoma expressing somatostatin: a highly malignant, rare tumor.

Poorly differentiated gastric neuroendocrine carcinomas, although rare, deserve particular attention, as they are aggressive and have an extremely poor prognosis. In this report we describe a gastric neuroendocrine carcinoma with rapidly fatal outcome. Immunohistological staining of the resected specimens revealed that the tumor was an endocrine carcinoma. The tumor disclosed intense immunoreactivity to pan-neuroendocrine markers and diffuse somatostatin immunoreactivity. There were no psammoma bodies and no demonstrable association with von Recklinghausen's neurofibromatosis. In the gastrointestinal tract, neuroendocrine tumors producing predominantly somatostatin have been described only in the duodenum. To the best of our knowledge, the present report is the second case report of a neuroendocrine gastric carcinoma expressing diffusely somatostatin as the only neuroendocrine regulatory peptide.

Portal thrombosis: late postoperative prevalence in Mansoni's schistosomiasis.

BACKGROUND/AIMS: Splenectomy with esophagogastric devascularization and distal splenorenal anastomosis are used for the treatment of bleeding esophageal varices in Mansoni's hepatosplenic schistosomiasis. Portal thrombosis followed by ascitis has been observed in the early postoperative phase, but there are no studies about the spontaneous and late postoperative prevalence of this vascular complication. The aim was to evaluate the spontaneous and late postoperative prevalence of total portal vein thrombosis and of ascitis in these patients. METHODOLOGY: US-Doppler examination was performed on 168 patients divided in three groups: 1) 92 non-operated (preoperative); 2) 62 after splenectomy with esophageal devascularization, 3) 14 after distal splenorenal anastomosis. The presence of ascitis was sought in all. RESULTS: Group 1 had 5.43% (5/92) of spontaneous total portal vein thrombosis, groups 2 and 3, presented 19.35% (12/62) and 50.00% (7/14) in the late postoperative follow-up, respectively. The Fisher's test showed that group 3 had higher incidence of this vascular occlusive complication (p = 0.038). No ascites were found. CONCLUSIONS: Surgical treatment of portal hypertension boosts the natural tendency to total portal vein thrombosis in this disease. The difference in the occurrence of this vascular complication during the late postoperative phase suggests the existence of a hemodynamic factor determined by the surgical technique.

Ampullary duodenal diverticulum and cholangitis.

CONTEXT: Ampullary duodenal diverticulum complicated by cholangitis is little known in clinical practice, especially when there are no gallstones in the common bile duct or there is no biliary tree ectasia or hyperamylasemia. A case of this association is presented, in which the surgical treatment was a biliary-enteric bypass. CASE REPORT: A 74-year-old diabetic white woman was admitted to the Taubat University Hospital, complaining of pain in the right upper quadrant, jaundice and fever with chills (Charcot's triad). She had had cholecystectomy 30 years earlier. She underwent clinical treatment with parenteral hydration, insulin, antibiotics and symptomatic drugs. Imaging examinations were provided for diagnosis: ultrasound, computed tomography and endoscopic retrograde cholangiopancreatography. The surgical treatment consisted of choledochojejunostomy utilizing a Roux-en-y loop. The postoperative period progressed without incidents, and a DISIDA scan demonstrated the presence of dynamic biliary excretion. The patient remained asymptomatic when seen at outpatient follow-up.

[Isolated Crohn's disease of the appendix as a source of enterorrhagia]. / Doença de Crohn isolada do apêndice cecal como causa de enterorragia.

BACKGROUND: Crohn's disease confined to the appendix is relatively rare as a sole primary manifestation of the disease. Young people are more affected. The medical history and the physical examination are similar to the findings in acute appendicitis, but the manifestations are protracted. On physical examination there are signs of peritoneal irritation and an abdominal mass is palpable in the right iliac fossa. AIMS: To report a case of Crohn's disease confined to the appendix and presenting with enterorrhagia. The source of the bleeding was localized by colonoscopy. PATIENT: A 16-year old caucasian male without past history of gastrointestinal symptoms, presented with two episodes of enterorrhagia within a period of one year. In the second episode colonoscopy identified the appendicular ostium as the source of bleeding. RESULTS: At operation the cecum and terminal ileum were normal in thickness and texture, and an inflammatory appendix adherent to the omentum was removed. Microscopically there were non-caseating granulomas, intense infiltration of the wall with plasma cells, lymphocytes and macrophages. The patient has not suffered recurrence, and a colonoscopy realized 2 years after the operation did not show signs of Crohn's disease. CONCLUSION: This case, like others in the literature, appendectomy is curative, but a 5-year follow-up is mandatory. When a young patient presents with enterorrhagia, this diagnosis has to be considered.

Pancreatic islet allograft in spleen with immunosuppression with cyclosporine. Experimental model in dogs.

PURPOSE: To study the functional behavior of the allograft with immunosuppression of pancreatic islets in the spleen. METHODS: Five groups of 10 Mongrel dogs were used: Group A (control) underwent biochemical tests; Group B underwent total pancreatectomy; Group C underwent total pancreatectomy and pancreatic islet autotransplant in the spleen; Group D underwent pancreatic islet allograft in the spleen without immunosuppressive therapy; Group E underwent pancreatic islet allograft in the spleen and immunosuppression with cyclosporine. All of the animals with grafts received pancreatic islets prepared by the mechanical-enzymatic method - stationary collagenase digestion and purification with dextran discontinuous density gradient, implanted in the spleen. RESULTS: The animals with autotransplant and those with allografts with immunosuppression that became normoglycemic showed altered results of intravenous tolerance glucose (p < 0.001) and peripheral and splenic vein plasmatic insulin levels were significantly lower (p < 0.001) in animals that had allografts with immunosuppression than in those with just autotransplants. CONCLUSIONS: In the animals with immunosuppression with cyclosporine subjected to allograft of pancreatic islets prepared with the mechanical-enzymatic preparation method (stationary collagenase digestion and purification with dextran discontinuous density gradient), the production of insulin is decreased and the response to intravenous glucose is altered.

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.

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.

[En bloc pancreaticoduodenectomy and right hemicolectomy for locally advanced right colon cancer treatment]. / Duodenopancreatectomia e hemicolectomia direita em monobloco para tratamento de câncer de cólon direito localmente avançado.

This article reports the case of a patient with a diagnosis of diarrhea and weight loss. Subsidiary exams showed ulcerovegetant lesion in the second duodenal portion and duodenocolic fistula. An exploratory laparotomy was performed and a neoplastic lesion in the hepatic angle of the colon was observed invading the second duodenal portion. The patient then underwent a cephalic gastroduodenopancreatectomy associated with en bloc right hemicolectomy and improved well in the postoperative period. Currently, 48 months after the surgery, he does not present any signs of the disease dissemination or recurrence. The consulted literature recommends that multivisceral resection must be considered if the patient is clinically able to undergo major surgery and does not present any signs of neoplastic dissemination, since the postoperative survival time is considerably longer in the resected group and some of these patients even achieve cure.

Esophagogastric anastomosis with invagination into stomach: New technique to reduce fistula formation.

AIM: To present a new technique of cervical esophagogastric anastomosis to reduce the frequency of fistula formation. METHODS: A group of 31 patients with thoracic and abdominal esophageal cancer underwent cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach tube. In the region elected for anastomosis, a transverse myotomy of the esophagus was carried out around the entire circumference of the esophagus. Afterwards, a 4-cm long segment of esophagus was invaginated into the stomach and anastomosed to the anterior and the posterior walls. RESULTS: Postoperative minor complications occurred in 22 (70.9%) patients. Four (12.9%) patients had serious complications that led to death. The discharge of saliva was at a lower region, while attempting to leave the anastomosis site out of the alimentary transit. Three (9.7%) patients had fistula at the esophagogastric anastomosis, with minimal leakage of air or saliva and with mild clinical repercussions. No patients had esophagogastric fistula with intense saliva leakage from either the cervical incision or the thoracic drain. Fibrotic stenosis of anastomoses occurred in seven (22.6%) patients. All these patients obtained relief from their dysphagia with endoscopic dilatation of the anastomosis. CONCLUSION: Cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach tube presented a low rate of esophagogastric fistula with mild clinical repercussions.

En bloc pancreaticoduodenectomy and right hemicolectomy to treat locally advanced right colon cancer: report of three cases.

Although colorectal tumors are fairly common surgical conditions, 5 to 12% of these tumors are locally advanced (T4 tumors) upon diagnosis. In this particular situation, the efficacy of en bloc multivisceral resection has been proven. When right-colon cancer invades the proximal duodenum or even the pancreatic head, a challenging dilemma arises due to complexity of the curative surgical procedure. Therefore, en bloc pancreaticoduodenectomy with right hemicolectomy should be performed to obtain free margins. The present study reports three cases of locally advanced right-colon cancer invading the proximal duodenum. All of these cases underwent successful en bloc pancreaticoduodenectomy plus right hemicolectomy, with no death occurrence. Long-term survival was observed in two cases (30 and 50 months). In the third case, the patient did not present any recurrence twelve months after surgical treatment. Multivisceral resection with en bloc pancreaticoduodenectomy should be considered for patients who present acceptable risk for major surgery and no distant dissemination. This approach seems justified since the length of postoperative survival is longer in radically ressected groups (R0) than in palliativelly resected groups (R1-2).

En-bloc pancreatoduodenectomy and right hemicolectomy for treating locally advanced right colon cancer (T4): a series of five patients.

A series of five cases of right-colon adenocarcinoma that invaded the proximal duodenum is presented. All patients underwent successful en-bloc pancreatoduodenectomy plus right hemicolectomy by General Surgery Service of the Teaching Hospital of the ABC Medical School, Santo André, SP, Brazil. The study was conducted between 2000 and 2007. There were two major complications but no mortality. Three patients did not present any recurrence over the course of 15 to 54 months of follow-up. Multivisceral resection with en-bloc pancreatoduodenectomy should be considered for patients who are fit for major surgery but do not present distant dissemination. Long-term survival may be attained.

[Comparative study of end-to-end cervical esophagogastric anastomosis with or without invagination after esophagectomy for cancer]. / Estudo comparativo entre as anastomoses cervicais esofagogástrica término-terminal com e sem invaginação após esofagectomia para câncer.

OBJECTIVE: To assess the incidence of fistula and stenosis of cervical esophagogastric anastomosis with invagination of the esophageal stump into the gastric tube in esophagectomy for esophagus cancer. METHODS: Two groups of patients with thoracic and abdominal esophagus cancer undergoing esophagectomy and esophagogastroplasty were studied. Group I comprised 29 patients who underwent cervical esophagogastric anastomosis with invagination of the proximal esophageal stump segment within the stomach, in the period of 1998 to 2007 while Group II was composed of 36 patients submitted to end-to-end cervical esophago-gastric anastomosis without invagination during the period of 1989 to 1997. RESULTS: In Group I, esophagogastric anastomosis by invagination presented fistula with mild clinical implications in 3 (10.3%) patients, whereas in Group II, fistulas with heavy saliva leaks were observed in 11 (30.5%) patients. The frequency of fistulas was significantly lower in Group I patients (p=0.04) than in Group II. In Group I, fibrotic stenosis of anastomoses occurred in 7 (24.1%) subjects, and 10 patients (27.7%) in Group II evolved with stenosis, while no significant difference (p=0.72) was found between the two groups. CONCLUSION: In esophagectomy for esophagus cancer, cervical esophagogastric anastomosis with invagination presented a lower rate of esophagogastric fistula versus anastomosis without invagination. Stenosis rates in esophagogastric anastomosis proved similar in both approach with or without invagination.

Síndrome de Fournier: estudo de 32 pacientes do diagnóstico à reconstrução / Fourniers gangrene: study of 32 patients from diagnosis to reconstruction

Objetivo: apresentar a experiência do serviço, enfatizando a importância do diagnóstico precoce, tratamento cirúrgico agressivo, ampla cobertura antibiótica e a necessidade de reconstrução do períneo destes pacientes. Material e Métodos: estudo de 32 pacientes consecutivos tratados de novembro de 1998 a janeiro de 2008. Resultados: 31 (96,8%) masculinos e um (3,2%) feminino. Quanto à etnia, 20 eram brancos, sete pardos e cinco negros. A idade variou entre 23 e 88 anos (média de 50,9 anos). A lesão inicial foi identificada em todos os casos, sendo o abscesso (genital/perianal) responsável por 27 (84,3%) dos pacientes. Os fatores associados estiveram presentes em 18 (56,3%) casos: diabetes mellitus em 10, alcoolismo em sete, paraplegia em seis, AIDS em três, obesidade em três e desnutrição em dois; destes cinco (15,6%) eram presidiários. O tratamento consistiu de desbridamento cirúrgico precoce e agressivo, com média de 1,5 por paciente. Realizaram-se quatro (12,5%) colostomias em alça e sete (21,8%) cistostomias. A associação de ceftriaxona com clindamicina foi utilizada em 15 (46,8%) pacientes. A reconstrução foi feita por: sutura primária ? nove casos (28,1%); retalhos cutâneos locais e cicatrização por segunda intenção ? sete casos (21,8%)/cada; enxertos de pele parcial ? seis casos(18,7%). Três pacientes morreram (9,3%). O tempo médio de permanência hospitalar foi de 26,1 dias. Conclusão: O diagnóstico precoce aliado ao desbridamento cirúrgico extenso são medidas importantes na contenção da rápida progressão da síndrome, associados a medidas de suporte clínico e ampla cobertura antimicrobiana. Os métodos de reconstrução têm um papel importante no sentido de minimizar as deformidades, restituindo ao paciente sua autoimagem.

Objective: to evaluate the experience of our institution, emphasizing the importance of early diagnosis, aggressive surgical débridement combined with broad-spectrum antibiotic, and the need for reconstruction of the perineum these patients. Methods: study of 32 consecutive patients treated from November 1998 to January 2008. Results: there were 31 (96.8%) males and one (3.2%) female. The patients ranged in age from 23 to 88 years (mean age 50.9 years). Of the 31 patients, 20 (62.5%) were white, seven (21.8%) were non-white and five (15.5%) were black. The primary lesion was localized in all cases, being the abscess (genital/perianal) responsible for 27 (84.3%) patients. There were a number of predisposing factors in eighteen patients (56.3%). Ten patients were diabetic, 7 were alcoholic, 6 were paraplegic, 3 had AIDS, 3 (9.3%) were obese. There was malnutrition in 2 (6.4%) and 5 (15.6%) were penitentiary inmates. The treatment consisted of precocious and wide surgical debridement which was performed in all patients. Most patients received multiple debridements (mean 1.5 per patient). There were 4 (12.5%) colostomies and 7 (21.8%) cistostomies. Fifteen patients (46.8%) received broad-spectrum antibiotic coverage (ceftriaxone associated with clindamicyn). Nine patients (28.1%) had primary suture, seven patients (21.8%) had local cutaneous grafts and second intention healing; three patients (9.3%) died. The average hospital stay was 26.1 days. Conclusion: FG requires a prompt diagnosis, immediate surgical treatment and antibiotic coverage. Methods of reconstruction are important not only for minimizing deformities but also for restoration of the patient autoimage.

Pancreatic islet allograft in spleen with immunossuppression with cyclosporine. Experimental model in dogs / Alotransplante de ilhotas pancreáticas no baço com imunossupressão com ciclosporina. Modelo experimental em cães

PURPOSE: To study the functional behavior of the allograft with immunosuppression of pancreatic islets in the spleen. METHODS: Five groups of 10 Mongrel dogs were used: Group A (control) underwent biochemical tests; Group B underwent total pancreatectomy; Group C underwent total pancreatectomy and pancreatic islet autotransplant in the spleen; Group D underwent pancreatic islet allograft in the spleen without immunosuppressive therapy; Group E underwent pancreatic islet allograft in the spleen and immunosuppression with cyclosporine. All of the animals with grafts received pancreatic islets prepared by the mechanical-enzymatic method - stationary collagenase digestion and purification with dextran discontinuous density gradient, implanted in the spleen.

CONCLUSIONS: In the animals with immunosupression with cyclosporine subjected to allograft of pancreatic islets prepared with the mechanical-enzymatic preparation method (stationary collagenase digestion and purification with dextran discontinuous density gradient), the production of insulin is decreased and the response to intravenous glucose is altered.

OBJETIVO: Avaliar o comportamento funcional do alotransplante com imunossupressão de ilhotas pancreáticas no baço. MÉTODOS: Foram utilizados cinco grupos de 10 cães mestiços: grupo A (controle) submetido aos exames bioquímicos; grupo B, submetido à pancreatectomia total; grupo C (autotransplante) submetido à pancreatectomia total e autotransplantação de ilhotas pancreáticas no baço; grupo D, submetido à alotransplantação de ilhotas pancreáticas no baço sem terapia imunossupressiva; grupo E, submetido à alotransplantação de ilhotas no baço e imunossupressão com ciclosporina. Todos os animais transplantados receberam ilhotas pancreáticas isoladas pelo método mecânico-enzimático, digestão estacionária com colagenase e purificação com gradiente de densidade descontínua de dextran e foram implantadas no baço. RESULTADOS: Animais autotransplantados e alotransplantados com imunossupressão que se tornaram normoglicêmicos apresentaram testes de tolerância à glicose intravenosa alterados (p<0,001) e o nível de insulina plasmática periférica e na veia esplênica foram significantemente menores (p<0,001) nos animais alotransplantados com imunossupressão em relação aos autotransplantados. CONCLUSÃO: Nos animais submetidos ao alotransplante de ilhotas pancreáticas com imunossupressão com ciclosporina e preparadas pelo método mecânico-enzimático, digestão estacionária com colagenase e purificação com gradiente de densidade descontínua de dextran, a produção de insulina está diminuída e a resposta à sobrecarga de glicose intravenosa alterada.

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.

Grandes hérnias incisionais / Giant incisional hernias

INTRODUÇÃO: A correção de hérnias incisionais abdominais permanece como um dos procedimentos cirúrgicos mais comuns uma vez que ela ocorre em cerca de 11 por cento das laparotomias. Vários são os fatores de risco. Surgem, em geral, nos primeiros cinco anos após a operação e seu manuseio ainda é controverso. OBJETIVO: Atualizar os meios e métodos empregados para a correção cirúrgica das hérnias abdominais gigantes. MÉTODO: Revisão da literatura com base no Pubmed, Scielo e Lilacs com cruzamento dos descritores "hérnia abdominal, próteses, complicações e técnicas cirúrgicas", e adicionando contribuição própria baseada na experiência dos autores no manuseio desta afecção. CONCLUSÃO: Mesmo as correções bem sucedidas, com a utilização ou não de grandes próteses, não são os procedimentos isentos de inconvenientes, pois a parede abdominal não retoma a sua elasticidade e complacência normais. Por este motivo, é importante que o paciente seja alertado da possibilidade da sua expectativa em relação ao resultado, tanto estético quanto funcional, não ser alcançada.

BACKGROUND: The correction of abdominal hernias remains one of the most common surgical procedures since it occurs in about 11 percent of laparotomies. There are several risk factors. Arise, in general, the first five years after the operation and their management is controversial. AIM: Update the means and methods for surgical repair of giant abdominal hernias. METHOD: Literature review based on PubMed, Lilacs and Scielo with crossing the keywords "abdominal hernia, prostheses, surgical techniques and complications", and adding its own contribution based on the authors' experience in handling this condition. CONCLUSION: Even the successful correction with the use of large prostheses, may happen procedure inconvenient, because the abdominal wall does not resume its elasticity and compliance at the normal. For this reason, it is important that the patient be advised of the possibility of their expectations regarding the outcome, both aesthetic and functional, not be achieved.

Duodenopancreatectomia e hemicolectomia direita em monobloco para tratamento de câncer de cólon direito localmente avançado / En bloc pancreaticoduodenectomy and right hemicolectomy for locally advanced right colon cancer treatment

This article reports the case of a patient whit a diagnosis of diarrhea and weight loss. Subsidiary exams showed ulcerovegetant lesion in the second duodenal portion and duodenocolic fistula. An exploratory laparotomy was performed and a neoplasic lesion in the hepatic angle of the colon was observed invading the second duodenal portion. The patient then underwent a cephalic gastroduodenopancreatectomy associated with en bloc right hemicolectomy and improved well in the postoperative period. Currently, 48 months after the surgery, he does not present any signs of the disease dissemination or recurrence. The consulted literature recommends that multivisceral resection must be considered if the patient is clinically able to undergo major surgery and does not present any signs of neoplasic dissemination, since the postoperative survival time is considerably longer in the resected group and some of these patients even achieve cure.
