Retromuscular mesh and hernial sac technique in the reconstruction of 139 cases of large median incisional hernias: one institution's experience.

PURPOSE: Incisional hernia is the most common complication of laparotomy. Postoperative parietal defects tend to relapse, even after the most optimal surgical methods. The aim of this study was to present the effectiveness of an adapted retromuscular technique with prolene mesh and a hernial sac, in patients with large incisional median hernias. The reported results were obtained by our team after more than 15 years of experience. METHODS: This retrospective study included 139 consecutive cases of large median incisional hernias operated on using a retromuscular mesh and hernial sac technique. The cross-sectional diameter of incisional hernias was larger than 10 cm, being classified in the W3 group, according to the European Hernia Society classification. RESULTS: The study included 83 females (59.71%) and 56 males (40.29%) with a median age of 62.4 ± 16.6 years and an average body mass index of 32.4 ± 7.6 kg. The hernia was supraumbilically located in 54 cases, subumbilically in 61 cases, and supra- and subumbilically in 24 cases. Postoperative complications were recorded in eight cases (5.75%): one case with a hematoma in the right abdominal muscle sheath; five cases with supra-aponeurotic seromas; two cases with skin necrosis and one with a mesh infection. Recurrence occurred in seven cases (5.03%): four cases in the first 2 years postoperatively and three cases in the third year after surgery. CONCLUSIONS: The retromuscular technique with prolene mesh and a hernial sac is an effective method of restoring the integrity of the abdominal wall in large median incisional hernias with low rates of morbidity and recurrence.

FIRST DAY SERUM CALCIUM AND PARATHYROID HORMONE LEVELS AS PREDICTIVE FACTORS FOR SAFE DISCHARGE AFTER THYROIDECTOMY.

CONTEXT: Permanent hypocalcemia is a rare but significant complication of thyroid surgery. OBJECTIVE: The aim of this study was to identify predictive factors of hypocalcemia and hypoparathyroidism after thyroidectomy. DESIGN: Study included 134 total patients submitted to thyroidectomy from two endocrine units (January 2015 - August 2016). METHODS: We measured total serum calcium (sCa) and intact PTH (iPTH) on postoperative day one and 1 month after surgery. RESULTS: 118 patients were women with F/M ratio of 7.3/1 and a mean age of 51.8 years. 64 patients were included in group A (iPTH <12 pg/mL) and 70 patients in group B (iPTH >12 pg/mL). sCa and hypocalcemia symptoms were correlated with iPTH, measured 24 hours after surgery. The cut-off value was for sCa 8.05 mg/dL with a sensitivity of 85.29% and a specificity of 88.0% and for iPTH 11.2 pg/mL, with a sensitivity of 82.3% and a specificity of 71.0%. SCa (< 8.05 mg/dL) was a predictive factor with a 99 (IC95%:12.86-761.58) and iPTH (<11.2 pg/mL) with a 10.77 higher risk (CI95%: 3.83-30.30) to be associated with symptoms. CONCLUSION: SCa and iPTH represent good predictive factors of early and safe hospital discharge and can predict the risk of prolonged and permanent hypoparathyroidism.

The effect of Tropaeolum majus L. on bacterial infections and in vitro efficacy on apoptosis and DNA lesions in hyperosmotic stress.

Tropaeolum majus L. (T. majus) or nasturtium is a medicinal plant widespread in the areas with temperate climate, commonly used in culinary and in traditional medicine due to therapeutic properties. In the last few years, various effects of the flowers and leaves of this plant have been studied, but their benefits are not fully known. The aim of the study was to identify the phenolic compounds from T. majus edible flowers in relation with its antioxidant capacity and the antimicrobial activity against different bacteria and Candida albicans. In addition, the impact of natural extract on oxidative stress, inflammation and apoptosis was analysed on human umbilical vein endothelial cells (HUVECs) exposed to normotonic and hypertonic conditions. The major phenolic acids, identified by HPLC-RP with UV detection, were gallic acid, caffeic acid and p-coumaric and predominant flavonoids were quercetin, epicatechin and luteolin. The both fractions of T. majus were rich sources of polyphenols with marked antioxidant activity, evidenced by TEAC or DPPH methods. The extract exhibited a week antibacterial effect on some strains of streptococcus, without antifungal or antibacterial effect on gram negative bacteria. T. majus extract increased the p53 and Bcl-2 expressions and diminished the DNA lesions indicating the protective and antiapoptotic effects in vitro, on endothelial cells exposed to hyperosmotic stress. These experimental findings suggest that T. majus can exert some protection against bacterial infections and reduce apoptosis and DNA lesions in hypertonic conditions.

INCIDENTAL PARATHYROIDECTOMY DURING THYROID SURGERY - RISK, PREVENTION AND CONTROVERSIES; AN EVIDENCE-BASED REVIEW.

BACKGROUND: Postoperative hypocalcemia after thyroid surgery has a high prevalence ( 16-55% in different series). Incidental parathyroidectomy (IP) is a less discussed complication of thyroidectomy with consequences not properly defined. The aim of our study was to find incidence, risk factors and how to prevent IP. METHODS: Extensive search of English literature publications via PubMed was performed and 73 papers from 1980 to 2017 were analysed using the GRADE system/classification, quality of evidence was classified as "strong" when the result is highly unlikely to change existing recommendation and "weak" when opposite. RESULTS: Incidence of IP is 3.7-24.9%, while prevalence of permanent hypoparathyroidism is less frequent 6-12%. Direct relation between IP and hypoparathyroidism/hypocalcemia remains controversial. Female patients, ectopic parathyroids, small thyroids, Graves', malignancy, redo surgeries and total thyroidectomy favour IP. Routine visualization of parathyroids, new hemostatic devices, magnifying instruments and fluorescence can prevent incidental removal of parathyroids. Incidence of IP during videoassisted or robotic thyroidectomies was similar to open procedures. High volume, experienced and younger surgeons have lower complication rates (including hypoparathyroidism). CONCLUSIONS: Incidental parathyroidectomy is more frequent than we might have expected. It should be avoided and parathyroid glands should be kept in situ. Majority of studies are retrospective (low degree of evidence according to previous mentioned GRADE classification) and further meta-analysis or randomized control studies are welcome in order to define the impact of incidental removal of parathyroids on postoperative outcome.

The utility of the predictive scores in polytrauma with abdomino-pelvic injuries: a series of 38 patients.

UNLABELLED: Trauma is the principal cause of mortality among the population under 40 years. The aim of our study was to compare predictive trauma scores and demonstrate their utility in the evaluation of the quality of care in polytrauma. MATERIAL AND METHODS: A retrospective study was performed between 2000-2011 including polytrauma patients with abdominal lesions and pelvic fracture who under went emergency laparotomy. We calculated ISS, GCS, RTS,TRISS, ASCOT trauma scores and W score for evaluation of treatment quality. RESULTS: We obtained the necessary data to calculate the predictive scores in 38 cases. Comparing the scores of the survivals and non-survivals we noted the following regarding mortality predictive scores: GCS 13.74 vs. 6.13 (p 0.0001),ISS 28.52 vs. 35 (p=0.0169), RTS 6.96 vs. 3.07 (p 0.0001),TRISS 84.67% vs. 28.7% (p 0.0001), ASCOT 10.34% vs.64.32% (p 0.0001). The W score in TRISS and ASCOT methodology was -2.05 (p=0.7997) and -7.81 (p=0.336),respectively. There was no statistically significant difference between actual and predicted mortality, the former being 39.47%. CONCLUSION: We did not observe differences between the two methodologies TRISS and ASCOT in mortality prediction (p=0.5401). Both of them can be used to predict polytrauma patient evolution. The W score is useful in treatment quality assessment.

The influence of homocysteine and oxidative stress on pregnancy outcome.

Oxidative stress in utero-placental tissues plays an important role in the development of placental-related diseases. Maternal hiperhomocysteinemia is associated with placental mediated diseases, such as preeclampsia, spontaneous abortion and placental abruption. The aim of our study is to appreciate the clinical usefulness of the dosage serum homocysteine and malondialdehyde, as an oxidative stress marker, in the pregnancies complicated with risk of abortion or preterm birth. The study was performed at the Obstetric Gynecology Clinical Hospital Oradea from December 2009 until April 2010. It included 18 patients with risk of abortion (group 1), 22 with preterm birth (group 2). The results were compared with a control group composed by 14 healthy pregnant women. Serum homocysteine level was measured by an enzymatic method, on the instrument Hitachi 912, Roche, reagent: Axis-Shield Enzymatic. For proving the oxidative stress we established the level of malondialdehyde using a method with thiobarbituric acid TBA (Kei Satoh 1978) and the level of ceruloplasmin with the Ravin method .Also AST, ALT,CRP, iron, uric acid, urea were assessed.High level of homocysteine in both groups of study in comparison with the control group was found. The concentration of MDA was significantly higher in pregnancies complicated with risk of abortion and preterm birth compared to the control group (p=0.040, p=0.031). Considerable differences of ceruloplasmin concentration between group 1 and group 2 (p=0.045), and between group 2 and control group (p=0.034), was noticed but not any important differences between group 1 and control group (p=0.683). In women with risk of abortion or with preterm birth an oxidative stress and a hyperhomocysteinemia are present.

Differential expression and processing of secretogranin II in relation to the status of pheochromocytoma: implications for the production of the tumoral marker EM66.

We have previously demonstrated that measurement of tissue concentrations of the secretogranin II (SgII or SCG2 as listed in the HUGO database)-derived peptide EM66 may help to discriminate between benign and malignant pheochromocytomas and that EM66 represents a sensitive plasma marker of pheochromocytomas. Here, we investigated the gene expression and protein production of SgII in 13 normal adrenal glands, and 35 benign and 16 malignant pheochromocytomas with the goal to examine the molecular mechanisms leading to the marked variations in the expression of EM66 in tumoral chromaffin tissue. EM66 peptide levels were 16-fold higher in benign than in malignant pheochromocytomas and had an area under the receiver-operating characteristic curve of 0.95 for the distinction of benign and malignant tumors. Q-PCR experiments indicated that the SgII gene was significantly underexpressed in malignant tumors compared with benign tumors. Western blot analysis using antisera directed against SgII and SgII-derived fragments revealed lower SgII protein and SgII-processing products in malignant tumors. Western blot also showed that low p-cAMP-responsive element-binding (CREB) concentrations seemed to be associated with the malignant status. In addition, the prohormone convertase PC1 and PC2 genes and proteins were overexpressed in benign pheochromocytomas compared with malignant pheochromocytomas. Low concentrations of EM66 found in malignant tumors are associated with reduced expression and production of SgII and SgII-derived peptides that could be ascribed to a decrease in SgII gene transcription, probably linked to p-CREB down-regulation, and to lower PC levels. These findings highlight the mechanisms leading to lower concentrations of EM66 in malignant pheochromocytoma and strengthen the notion that this peptide is a suitable marker of this neuroendocrine tumor.

Polycystic liver disease with complications: fenestration by laparoscopic approach.

AIM: Isolated polycystic liver disease is a rare congenital cystic liver disease with autosomal dominant transmission. Its main feature is the presence of a large number of cysts of different sizes in the hepatic parenchyma, which have a benign evolution. METHOD: We present the case of an 80 years old male patient with massive polycystic liver disease, diagnosed three years ago by ultrasound examination and abdominal computed tomography scan. The evolution of the disease had been complicated by compressive symptoms, caused by the large dimensions of the cysts. The patient presented with abdominal pain, nausea, vomiting and lost weight. Cyst fenestration through laparoscopic approach resolved the symptoms. RESULTS: The patient was mobilized on the day of the surgery, and was discharged on the 9th postoperative day, after drainage tube removal. CONCLUSIONS: Isolated polycystic liver disease is rare. Surgical treatment is indicated only if complications occur. The laparoscopic approach is an alternate treatment method, if needed. The patients benefit from the advantages of minimally invasive surgery.

[Lymphatic and vascular invasion in laryngeal and pyriform sinus carcinomas]. / Die lymphatische und vaskuläre Ausbreitung von Larynx- und Sinus piriformis Plattenepithelkarzinomen.

BACKGROUND: To investigate prognostic significance of the lymphatic and vascular invasion in patients with squamous cell carcinoma of the larynx and pyriform sinus. MATERIAL AND METHODS: Patients with squamous cell carcinoma of the larynx and pyriform sinus who underwent laryngectomies between 2002 and 2006 in the ENT Clinic of Cluj-Napoca were investigated for lymphatic and vascular invasion and their effect on disease-free survival and recurrence rates. RESULTS: The present study included 396 patients. The mean disease-free survival of patients with or without lymphatic invasion was statistically significant (p=0.000000). The mean disease-free survival of patients with or without vascular invasion was statistically significant (p=0.000021). In multivariant analysis, the lymphatic invasion was significantly correlated only with surgical resection borders (p=0.0004), while vascular invasion was significantly correlated with surgical resection borders (p=0.0000), nodes diameter (p=0.0075) and postoperative radiotherapy and/or chemotherapy (p=0.0002). CONCLUSION: Lymphatic and vascular invasion have a significant prognostic value and influence the disease-free survival, regional and distant metastasis rates significantly.

[Left mesiotemporal lesions and anterograde memory impairement: a case of neurosyphilis]. / Lésions mésiotemporales gauches et amnésie antérograde: un cas de neurosyphilis.

INTRODUCTION: Neurosyphilis has become uncommun in the developed countries. OBSERVATION: We report a case of neurosyphilis with limbic presentation, left mesiotemporal lesions on MRI and severe anterograde amnesia. DISCUSSION: Pathogeneses of MRI findings are unknown. We suggest the implication of arteritis wich affects small vessels, parenchymatous and excitotoxic lesions. The absence of mesiotemporal lesion in immunodeficient patients, the limbic systematization of pathology underlines the involvement of probably auto-immune process. Neurosyphilis should always be considered in the differential diagnosis of limbic encephalitis in order to initiate treatment and to prevent cognitives sequelaes. At last, partial status epilepticus should be diagnosed and excitotoxicity lesions prevents with antiepileptic treatment.

[Gastric stromal tumor with liver and subcutaneus metastasis. Case report]. / Tumora stromala gastrica cu metastaze hepatice si subcutanate. Prezentare de caz.

UNLABELLED: The gastrointestinal stromal tumours expand from the undefine mezenchimal cells of the intestinal wall and the origin is in the Cajal interstitial cells. The agresivity of GIST is difficult to be evaluate. Very importants factors for grading are the tumour localisation, the invasion of serosa or mucosa, the dimensions of tumour and the number of mytosis. We present a case with haemoragic gastric stromal tumour, with small dimensions, which was initially diagnosed as a "benign" tumour. Seven years after the operation, the patient presented voluminous liver metastases. After right hepathectomy and medical treatment with Glivec we followed up the case. Eleven years after the first operation she presented a subcutaneus metastasis in parietal region, which was confirmed with imunohistochemical exam. The patient is still under observation with higher doses of Glivec. CONCLUSIONS: The gastrointestinals stromal tumours represent a very rare group of digestive tract tumors, with malignant potentially evolution; the first choice of treatment is surgery, with complete ablation of the tumour. The medical treatment with Glivec is necessary in case of reccurence or metastases; the stromal tumours present a strange evolution, for this reason all the patients must be under medical observation, for the rest of their life.

[Local recurrence after the sphincter-saving operations and abdominal perineal resection in rectal cancer]. / Recidiva tumorala locala dupa chirurgia conservatoare si rezectia abdominoperineala în cancerul rectal.

By local recurrence we define the appearance of the same anatomopathological type of cancer like the one initially described in the primary tumor, limited at the rectum or pelvis.The study is based on the analysis of all the cases with rectal cancer who undergone surgical procedures in Surgical Clinic No.2 Tg. Mures in the last 5 years. Using the most important parameters for each patient we identified some risk factors for the recurrence of the rectal cancer: surgical procedures--there were no major variations in the local recurrence between the sphincter-saving operations and abdominal perineal resections. The most frequent recurrence tumors appeared after Hartmann I operation; the moderate aggressive adenocarcinomas at the old patients and high aggressive adenocarcinomas in young patients, T3, T4 stages. The recurrent rectal cancer is more frequent in aged patients with high aggressive adenocarcinomas. There were no major differences in recurrence rate between the sphincter-saving operations and abdominal perineal procedures.

Utilidad de la citometría de flujo para valorar el efecto de la atorvastatina sobre la función plaquetaria y la movilización del Ca2+ en pacientes hiperlipémicos / Usefulness of flow cytometry in assessing the effect of atorvastatin on platelet function and Ca2+ in hyperlipemic patients

Introducción. En pacientes hiperlipémicos resultan frecuentes los procesos trombóticos, en los que las plaquetas desempeñan un papel decisivo. La presencia de plaquetas activadas circulantes, descrito en un trabajo anterior, constituye un importante factor de riesgo trombótico, por lo que resulta de gran interés disponer de un fármaco hipolipemiante que, además de normalizar los lípidos plasmáticos, también disminuya la activación de las plaquetas circulantes.Los principales objetivos del presente estudio son valorar si la mayor activación plaquetaria de los pacientes hipercolesterolémicos se acompaña de cambios en la movilización del calcio libre citoplasmático plaquetario y si dichas alteraciones se normalizan mediante la medicación con atorvastatina. Material y métodos. Para alcanzar éstos objetivos se estudian 30 pacientes hipercolesterolémicos y 40 controles normolipémicos. En sangre anticoagulada con citrato, se determina el porcentaje plaquetas CD62+, el número de microagregados plaquetarios formados espontáneamente (MAP/5.000 plaquetas) y la movilización del calcio libre citoplasmático. Para ello, se utiliza un citómetro EPICS-XL, y los anticuerpos y fluorocromos CD61.PE, CD62.FITC y FURA3-AM. Los pacientes se estudian antes y después de 2 meses de tratamiento con atorvastatina (20mg/día). Resultados. Los resultados obtenidos indican que el tratamiento con atorvastatina disminuye significativamente la concentración de colesterol total, colesterol unido a lipoproteínas de baja densidad (cLDL) y triglicéridos. En paralelo se observa una disminución del % plaquetas circulantes CD62+ (2,41±1,55% a 1,45±1,06%; p<0,05) y del número de MAP (390±43 a 322±48; p<0,05). Estos cambios se acompañan de la normalización de la movilización del Ca2+ libre citoplasmático plaquetario. Conclusiones. Como conclusión, se observa que la citometría de flujo de sangre entera constituye una técnica útil para abordar temas tales como los planteados en el presente trabajo. Los pacientes hipercolesterolémicos presentan mayor activación plaquetaria, que se acompaña de la formación de microagregados plaquetarios y de cambios en la movilización del Ca2+, que se normalizan mediante el tratamiento con atorvastatina, hecho que no se ha comunicado previamente en la bibliografía revisada (AU)

Introduction. Thrombotic events are common in hyperlipemic patients in which platelet activation play a decisive role. The presence of activated platelets, as described in a previous paper, is a major risk factor for thrombosis in patients with a high plasma cholesterol and it is therefore of great interest to have a lipid lowering drug that, in addition to normalising plasma lipids, also decreases this activation of circulating platelets. The main aims of this study are to assess whether the increased platelet activation in hypercholesterolemic patients is accompanied by changes in cytoplasmic free calcium mobilisation in platelets and the formation of platelet microaggregates, and whether these changes are normalised by treatment with atorvastatin. Material and methods. To achieve these aims 30 hypercholesterolemia patients and 40 normolipemic controls were recruited. The percentage of CD62 positive platelets, the number of spontaneously formed platelet microaggregates (MAP/5000 platelets) and the free calcium mobilization in platelets were evaluated in citrated blood . An EPICS-XL flow cytometer and the antibodies and fluorochromes CD61.PE, CD62.FITC and FLUO3-AM were used for this study. The patients were evaluated before and after two months of atorvastatin (20mg/day) treatment. Results. The results show that atorvastatin treatment significantly decreases the plasma concentration of total and LDL-Cholesterol and triglycerides. In parallel a decrease was noted in the percentage of activated circulating CD62 positive platelets (2.41±1.55% to 1.45±1.06%, P<0.05) and also in the number of spontaneously formed MAP (390±43 to 322±48, P<0.05). These changes were accompanied by the normalization in the free calcium mobilization in platelets. Conclusions. As a conclusion it is noted that the flow cytometry of whole blood is a useful technique for evaluating aspects such as those raised in this study. Hypercholesterolemia patients showed more spontaneous platelet activation, which was accompanied by the formation of platelet microaggregates and changes in the cytoplasmic free calcium mobilization, which were normalised by treatment with atorvastatin, which has not been previously reported in the literature (AU)

The metabolic and inflammatory profile in obese patients with chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease and obesity are major causes of morbidity and mortality worldwide and, according to current data, the global burden of these conditions will increase further. Obesity plays a major role in the development of the metabolic syndrome and has been identified as an important risk factor for chronic diseases such as type 2 diabetes mellitus and cardiovascular disease. Adiposity is associated with insulin resistance even over relatively normal ranges of body fatness. There is strong evidence that altered adipose tissue function plays a crucial role in the pathogenesis of obesity-related insulin resistance and type 2 diabetes, as has recently been reviewed. Obesity is linked to respiratory diseases such as obstructive sleep apnea syndrome and obesity hypoventilation syndrome and accumulating evidence suggests an association between obesity and asthma. A potential link between obesity and COPD is also increasingly recognized although little data is known about the mechanisms underlying this association. The inflammatory and metabolic profile differs between obese with COPD and normo or underweight with COPD in part due to dysfunction of adipose tissue.

Are systemic inflammatory profiles different in patients with COPD and metabolic syndrome as compared to those with COPD alone?

BACKGROUND: Metabolic Syndrome (MS) is frequent in patients with COPD, almost 50% of patients with COPD had one or more components of metabolic syndrome (MS). Moreover, it was demonstrated that BMI might be one of the determinants of COPD phenotype. Chronic comorbid diseases affect health outcomes in COPD, in fact, patients with COPD mainly die of non-respiratory disorders such as cardiovascular disease. Inflammation plays a key role in COPD and MS but we do not know the real inflammatory profile of these patients. A better understanding of the origin and consequences of systemic and local inflammation, and of potential therapies, will most likely lead to better care of patients with COPD. METHODS: We compared 64 consecutive, consenting smoker patients with COPD and MS (mean age: 62.7 +/- 0.7 years) with this serum inflammatory profile (hsCRP: 1.9 +/- 0.01 mg/dL, TNF-alpha: 6,4 +/- 0.1 pg/mL, adiponectin: 4.7 +/- 0.01 mg/L) versus 69 COPD smoker patients matched for age (mean age 61.4 +/- 0.4 years) with following serum inflammatory cytokine (CRP: 0.9 +/- 0.01 mg/dL, TNF-alpha: 3.9 pg/mL +/- 0.01, adiponectin: 9.3 +/- 0.01 mg/L). COPD and MS was diagnosed according to the GOLD criteria respectively IFD 2005 criteria. Data were expressed as mean +/- SE (standard error). Comparisons of parameters among the two groups were made by Student unpaired t test. The level of statistical significance was set as p < 0.05. RESULTS: Serum TNF-alpha and high-sensitivity CRP levels in patients with COPD and MS were significantly higher (p < 0.05) than those of COPD alone. Plasma adiponectin levels in patients with COPD were significantly higher (p < 0.05) than in subjects with COPD and MS. CONCLUSIONS: Patients with COPD and MS have a more exacerbated systemic inflammatory profile and a significantly reduced specific adipose response represented by adiponectin than patients with COPD alone. These results help us to better understand the inflammatory pattern in patients with COPD with metabolic disorders and permit us to sustain the regulatory role of adiponectin in metabolism balance. It is possible that this association between COPD and MS with a specific inflammatory pattern (high serum levels of CRP and TNF-a but with low plasma levels of adiponectin) to explain the high rate of death adjudicated as due to cardiovascular causes.

[Long-term follow up after surgery for intractable ascites]. / Rezultate tardive ale tratamentului chirurgical pentru ascita netratabila.

The aim of the study is to evaluate the outcome of a selected group of 24 patients who underwent surgery for refractory ascites, in a 10 years period, 1995-2005. CLINICAL DIAGNOSIS: Alcoholic cirrhosis (n=18), inferior cava thrombosis (n=2), splenic vein thrombosis (n=1), cryptogenic cirrhosis (n=3), with association of variceal bleeding and refractory ascites. The surgical procedures consisted of porto-sistemic shunts (n=12), peritoneo-saphene shunts (n=10), mesenterico-caval shunt (n=1), mesenterico-right atrium shunt (n=1). Early results were very good: no postoperative mortality, no general haemo-dinamic failure, no renal fonctional failure, no encephalopathy. 7 of 10 peritoneo-saphene shunts had an excelent evolution, but in three cases the results were unsatisfactory, the patients continuing the medical treatment. Except one patient who died after 2 years, for B virus and alcoholic abuse, all the patients survived 5 or more years. There was not evidence of digestive hemorrhage or uncontrolable encephalopathy and thrombocytopenia. The grade of esophageal varices was mantained lower than II, ascites remained minimum or absent, and biological parameters were normal or slightly elevated. CONCLUSIONS: In the absence of the technical and economical possibilities of TIPS and liver transplantation, surgery for intractable ascites is a good option in selected patients, especially in the absence of viruses and alcohol consumption, and can improve complications in the natural evolution of the disease.

Two-step hepatectomy with right portal branch ligature for a right lobe metastasis.

AIMS/BACKGROUND: Hepatic resection is the only treatment with possible curative effect both for primary and secondary tumors. An increase of the rate of resectability for tumors considered inoperable at first and a decrease of the postoperative morbidity and mortality can be realized by right portal branch ligature and two-step hepatectomy. METHODOLOGY: This paper presents the case of a patient with left bowel cancer with a hepatic metastasis. A right portal branch ligature was performed followed by systemic postoperative chemotherapy. RESULTS: The right portal branch occlusion was followed by right lobe atrophy and left lobe hypertrophy, confirmed by CT scan. Three months after the portal occlusion a right lobe hepatectomy was performed. The postoperative evolution was favorable; eight days of hospitalization were necessary. CONCLUSIONS: Portal branch ligature can be performed in certain cases of hepatic tumors to increase the resectability rate.

Two-step hepatectomy with right portal branch ligature for a right lobe metastasis.

Hepatic resection is the only treatment with possible curative effect both for primary and secondary tumors. An increase of the rate of resectability for tumors considered inoperable at first, and a decrease of the postoperative morbidity and mortality can be realized by right portal branch ligature and two-step hepatectomy. We would like to present the case of a patient with left bowel cancer with a hepatic metastasis. Right portal branch ligature was performed which was followed by systemic postoperative chemotherapy. The right portal branch occlusion was followed by right lobe atrophy and left lobe hypertrophy, confirmed by CT scanning. Three months after the portal occlusion the patient underwent a right lobe hepatectomy. The postoperative evolution was favorable, eight days of hospitalization were necessary. The portal branch ligature can be made in several cases of hepatic tumors to increase the resectability rate.

Bone metastases from differentiated thyroid carcinoma.

The presence of distant metastases from differentiated thyroid carcinoma decreases the 10-year survival of patients by 50%. Bone metastases represent a frequent complication especially of follicular thyroid cancer and severely reduce the quality of life causing pain, fractures, and spinal cord compression. Diagnosis is established by correlating clinical suspicion with imaging. Imaging is essential to detect, localize, and assess the extension of the lesions and should be used in conjunction with clinical evidence. Bone metastases are typically associated with elevated markers of bone turnover, but these markers have not been evaluated in differentiated thyroid cancer. Skeletal and whole-body magnetic resonance imaging and fusion 2-deoxy-2-[18F]fluoro-D-glucose whole-body positron emission tomography/computed tomography (PET/CT) are the best anatomic and functional imaging techniques available in specialized centers. For well-differentiated lesions, iodine-PET scan combined (124)I-PET/CT is the newest imaging development and (131)I is the first line of treatment. Bisphosphonates reduce the complications rate and pain, alone or in combination with radioiodine, radionuclides, or external beam radiotherapy and should be employed. Surgery and novel minimally invasive consolidation techniques demand an appropriate patient selection for best results on a multimodal approach. Basic research on interactions between tumor cells and bone microenvironment are identifying potential novel targets for future more effective therapeutic interventions for less differentiated tumors.

[Endocrine tumors of the gastro-intestinal tract (Carcinoid tumors)]. / Prise en charge chirurgicale des tumeurs endocrines du tractus gastro-intestinal.

Surgical management of gastro-intestinal endocrine tumors has to be adapted to tumor localization and disease extension (local and general). The aim of this literature review was to define surgical management of these unfrequent tumors.
