RESUMO

OBJECTIVES: Malnutrition after heart transplantation (HTX) is related to graft sclerosis. The risk for malnutrition is often underestimated by conventional measurements. We aimed to compare these with objective assessors for malnutrition. METHODS: Recipients at least five yr after HTX were included. Body mass index (BMI), bioimpedance analysis (BIA), serum albumin (SA) and subjective global assessment (SGA) malnutrition, and concomitant diseases were assessed. The BIA was used as gold standard, and a phase difference (PD) <4 was defined as cutoff. RESULTS: Sixty recipients (47 male, 13 female) were analyzed. The prevalence of malnutrition was according to SGA 6.6% (4/60), BMI 8.3% (5/60), SA 31.6% (19/60), and BIA 48.3% (19/60). PD values did not correlate with BMI (r = 0.118; p = 0.079) or SGA (r = 0.289; p = 0.65), but with SA (r = 0.458; p = 0.001). Multivariate analysis yield SA and sCr as independent predictors for an existing malnutrition. ROC analysis showed an area under the receiver operating characteristic curve of 0.606 for SA as compared to 0.515 for the BMI and 0.698 for sCr in the prediction of existing malnutrition as defined by the PD. CONCLUSION: The BMI or the SGA did not show as much power in predicting an existing alimentary deficiency for heart recipients as did SA.

RESUMO

BACKGROUND: Sportsmen's groin (SG) is a clinical diagnosis of chronic, painful musculotendinous injury to the medial inguinal floor in the absence of a groin hernia. Long-term results for laparoscopic inguinal hernia repair, especially data on health-related quality of life (HRQOL), are scant and there are no available data whatsoever on HRQOL after SG. The main goal of this study was to compare postoperative QOL data in the long term after transabdominal preperitoneal hernioplasty (TAPP) in groin hernia and SG patients with QOL data of a normal population. METHODS: This study included all patients (n = 559) who underwent TAPP repair between 2000 and 2005. Forty seven patients (8.4 %) were operated on for SG. We sent out the Short Form 36 Health Survey (SF-36) questionnaire for QOL evaluation. QOL data were compared with data from an age- and sex-matched normal population. RESULTS: Ultimately, 383 completed questionnaires were available for evaluation (69 % response rate). The mean follow-up time was 94 ± 20 months. In the SG group there were statistically significant differences in three subscales of the SF-36 and the mental component summary measure, showing better results for the SG group compared to the sex- and age-matched normal group data. There were no statistically significant differences between groin hernia patients and the sex- and age-matched normal population. CONCLUSION: TAPP repair for SG as well as groin hernia results in good HRQOL in the long term. Results for SG patients are comparable with QOL data of a normal population or even better.

RESUMO

BACKGROUND: Despite significant improvements in perioperative mortality as well as response rates to multimodality treatment, results after surgical resection of pancreatic adenocarcinoma with respect to long-term outcomes remain disappointing. Patient recruitment for prospective international trials on adjuvant and neoadjuvant regimens is challenging for various reasons. We set out to assess the preconditions and potential to perform perioperative trials for pancreatic cancer within a well-established Austrian nationwide network of surgical and medical oncologists (Austrian Breast & Colorectal Cancer Study Group). METHODS: From 2005 to 2010 five high-volume centers and one medium-volume center completed standardized data entry forms with 33 parameters (history and patient related data, preoperative clinical staging and work-up, surgical details and intraoperative findings, postoperative complications, reinterventions, reoperations, 30-day mortality, histology, and timing of multimodality treatment). Outside of the study group, in Austria pancreatic resections are performed in three "high-volume" centers (>10 pancreatic resections per year), three "medium-volume" centers (5­10 pancreatic resections per year), and the rest in various low-volume centers (<5 pancreatic resections per year) in Austria. Nationwide data for prevalence of and surgical resections for pancreatic adenocarcinoma were contributed by the National Cancer Registry of Statistics of Austria and the Austrian Health Institute. RESULTS: In total, 492 consecutive patients underwent pancreatic resection for ductal adenocarcinoma. All postoperative complications leading to hospital readmission were treated at the primary surgical department and documented in the database. Overall morbidity and pancreatic fistula rate were 45.5 % and 10.1 %, respectively. Within the entire cohort there were 9.8 % radiological reinterventions and 10.4 % reoperations. Length of stay was 16 days in median (0­209); 12 of 492 patients died within 30 days after operation, resulting in a 30-day mortality rate of 2.4 %. Seven of the total 19 deaths (36.8 %) occurred after 30 days, during hospitalization at the surgical department, resulting in a hospital mortality rate of 3.9 % (19/492). With a standardized histopathological protocol, there were 70 % (21/30) R0 resections, 30 % (9/30) R1 resections, and no R2 resections in Vienna and 62.7 % (32/51) R0 resections, 35.3 % (18/51) R1 resections, and 2 % (1/51) R2 resections in Salzburg. Resection margin status with nonstandardized protocols was classified as R0 in 82 % (339/411), R1 in 16 % (16/411), and R2 in 1.2 % (5/411). Perioperative chemotherapy was administered in 81.1 % of patients (8.3 % neoadjuvant; 68.5 % adjuvant; 4.3 % palliative); chemoradiotherapy (1.6 % neoadjuvant; 3 % adjuvant; 0.2 % palliative), in 4.9 % of patients. The six centers that contributed to this registry initiative provided surgical treatment to 40 % of all Austrian patients, resulting in a median annual recruitment of 85 (51­104) patients for the entire ABCSG-group and a median of 11.8 (0­38) surgeries for each individual department. CONCLUSIONS: Surgical quality data of the ABCSG core pancreatic group are in line with international standards. With continuing centralization the essential potential to perform prospective clinical trials for pancreatic adenocarcinoma is given in Austria. Several protocol proposals aiming at surgical and multimodality research questions are currently being discussed

RESUMO

Cellular responses induced by surgical procedure or ischemia-reperfusion injury (IRI) may severely alter transcriptome profiles and complicate molecular diagnostics. To investigate this effect, we characterized such pre-analytical effects in 143 non-malignant liver samples obtained from 30 patients at different time points of ischemia during surgery from two individual cohorts treated either with the Pringle manoeuvre or total vascular exclusion. Transcriptomics profiles were analyzed by Affymetrix microarrays and expression of selected mRNAs was validated by RT-PCR. We found 179 mutually deregulated genes which point to elevated cytokine signaling with NFκB as a dominant pathway in ischemia responses. In contrast to ischemia, reperfusion induced pro-apoptotic and pro-inflammatory cascades involving TNF, NFκB and MAPK pathways. FOS and JUN were down-regulated in steatosis compared to their up-regulation in normal livers. Surprisingly, molecular signatures of underlying primary and secondary cancers were present in non-tumor tissue. The reported inter-patient variability might reflect differences in individual stress responses and impact of underlying disease conditions. Furthermore, we provide a set of 230 pre-analytically highly robust genes identified from histologically normal livers (<2% covariation across both cohorts) that might serve as reference genes and could be particularly suited for future diagnostic applications.

RESUMO

Metabolomic profiles of tissues could greatly contribute to advancements in personalized medicine but are influenced by differences in adopted preanalytical procedures; nonhomogeneous pre- and post-excision ischemia times are potential sources of variability. In this study, we monitored the impact of ischemia on the metabolic profiles, acquired with high-resolution magic-angle-spinning (1)H NMR, of 162 human liver samples collected during and up to 6 h after routine surgery. The profiles changed significantly as a function of intraoperative warm ischemia (WI) and postresection cold ischemia (CI) time, with significant variations in the concentration of the same 16 metabolites. Therefore, a tight control of the preanalytical phase is essential for reliable metabolomic analyses of liver diseases. The NMR profiles provide a reliable "fingerprint" of ischemia and have predictive value: the best-performing predictive models are found to discriminate extreme time points of CI (0' vs 360 ') in the training set with cross-validation accuracy of ~90%; samples in the validation cohort can discriminate short (≤60') from long (≥180') CI with an accuracy of ~80%. For WI, the corresponding figures are 95.6 and 92%, respectively. Therefore, ischemia NMR profiles might become a tool for tissue quality control in biobanks.

RESUMO

Gallstone ileus is a rare cause of bowel obstruction. Here we report about two cases with clinical findings and therapy options. Both patients were presented with typical ileus-like symptoms, although the surgical treatment differs due to the CT scan and intraoperative findings. There are many methods for treating patients with Bouveret syndrome. Endoscopy should be the first treatment option for young patients with no significant diseases in the medical history, depending on the size of the stone. Surgical approach is the next possible option. Combination of these two methods is associated with higher mortality. In case there is no extraluminal gas or intraperitoneal fluid in CT-scan, there is no need for an acute surgery. Conservative therapy prior to the intervention enables a precise planning of whether the endoscopic approach or open surgery would be beneficial for the patient.

RESUMO

BACKGROUND AND AIMS: Post-operative hyperbilirubinaemia in patients undergoing liver resections is associated with high morbidity and mortality. Apart from different known factors responsible for the development of post-operative jaundice, little is known about the role of hepatobiliary transport systems in the pathogenesis of post-operative jaundice in humans after liver resection. METHODS: Two liver tissue samples were taken from 14 patients undergoing liver resection before and after Pringle manoeuvre. Patients were retrospectively divided into two groups according to post-operative bilirubin serum levels. The two groups were analysed comparing the results of hepatobiliary transporter [Na-taurocholate cotransporter (NTCP); multidrug resistance gene/phospholipid export pump(MDR3); bile salt export pump (BSEP); canalicular bile salt export pump (MRP2)], heat shock protein 70 (HSP70) expression as well as the results of routinely taken post-operative liver chemistry tests. RESULTS: Patients with low post-operative bilirubin had lower levels of NTCP, MDR3 and BSEP mRNA compared to those with high bilirubin after Pringle manoeuvre. HSP70 levels were significantly higher after ischaemia-reperfusion (IR) injury in both groups resulting in 4.5-fold median increase. Baseline median mRNA expression of all four transporters prior to Pringle manoeuvre tended to be lower in the low bilirubin group whereas expression of HSP70 was higher in the low bilirubin group compared to the high bilirubin group. DISCUSSION: Higher mRNA levels of HSP70 in the low bilirubin group could indicate a possible protective effect of high HSP70 levels against IR injury. Although the exact role of hepatobiliary transport systems in the development of post-operative hyper bilirubinemia is not yet completely understood, this study provides new insights into the molecular aspects of post-operative jaundice after liver surgery.

RESUMO

INTRODUCTION: Right-sided and left-sided colorectal cancer (CRC) is known to differ in their molecular carcinogenic pathways. The prevalence of sarcopenia is known to worsen the outcome after hepatic resection. We sought to investigate the prevalence of sarcopenia and its prognostic application according to the primary CRC tumor site. METHODS: 355 patients (62% male) who underwent liver resection in our center were identified. Clinicopathologic characteristics and long-term outcomes were stratified by sarcopenia and primary tumor location (right-sided vs. left-sided). Tumors in the coecum, right sided and transverse colon were defined as right-sided, tumors in the left colon and rectum were defined as left-sided. Sarcopenia was assessed using the skeletal muscle index (SMI) with a measurement of the skeletal muscle area at the level L3. RESULTS: Patients who underwent right sided colectomy (n = 233, 65%) showed a higher prevalence of sarcopenia (35.2% vs. 23.9%, p = 0.03). These patients also had higher chances for postoperative complications with Clavien Dindo >3 (OR 1.21 CI95% 0.9-1.81, p = 0.05) and higher odds for mortality related to CRC (HR 1.2 CI95% 0.8-1.8, p = 0.03).On multivariable analysis prevalence of sarcopenia remained independently associated with worse overall survival and disease free survival (overall survival: HR 1.47 CI 95% 1.03-2.46, p = 0.03; HR 1.74 CI95% 1.09-3.4, p = 0.05 respectively). CONCLUSION: Sarcopenia is known to have a worse prognosis in patients with CRLM and CRC. Depending on the primary location sarcopenia has a variable effect on the outcome after liver resection.

RESUMO

Internal hernia is a rare cause of intestinal obstruction. The risk of internal herniation is higher in some patients after abdominal surgery or with certain anatomical anomalies. Here, we present a case of an 80-year-old patient with incarcerated internal hernia through the foramen of Winslow due to an anatomical abnormality.

RESUMO

BACKGROUND: The incidence of diaphragmatic rupture is low; however, it may be life threatening. Normally caused by blunt trauma, some cases are reported after pulmonary infections with extensive coughing. Covid 19 causes pulmonary infections and pneumonia and has been associated with weakening of the diaphragm after prolonged ventilation. We present a patient who suffered from diaphragmatic rupture 2 months after recovering from a severe Covid 19 pneumonia. CASE: A 71 years old male patient presented with massive thoraco-abdominal pain and severe dyspnea. At the time of admission, the patient was diagnosed with rupture of the diaphragm and developed cardiogenic shock. Intraoperatively there was a 4 cm diameter large rupture of the diaphragm with enterothorax (transverse colon, stomach, spleen, parts of the jejunum). Avulsion of the mesenteric arteries made a segmental resection of the jejunum together with the spleen necessary. A jejuno-jejunostomy was performed and organs were replaced into the abdomen. The rupture of the diaphragm underwent primary closure with non-resorbable suture material. The patient has shown an uneventful post-operative course, fully recovered and was discharged on day 11 after surgery. CONCLUSION: Covid 19 is a disease that is known to have various effects on different organs. The diaphragm is only paid heed in case of dysfunction. Also in the setting of Covid 19 it is not known as prominent effector organ. Nevertheless its affection by coughing caused by Covid 19 can lead to life threatening complications.

RESUMO

BACKGROUND/AIM: Pancreatic intraepithelial neoplasia (PanIN) is the most common precursor lesion to pancreatic adenocarcinoma (PDAC). Yet no criteria to quantify patients at risk for progression to PDAC with PanIN exist. Platelet to lymphocyte ratio is an inflammatory marker that has been associated with overall survival in patients with invasive malignancies including pancreatic cancer. Preoperative sarcopenia has been linked to more aggressive diseases in pancreatic neoplasms. We aimed to assess a relation between PLR and sarcopenia as predictors for tumor progression in patients undergoing pancreatic resection for IPMN. PATIENTS AND METHODS: We retrospectively reviewed 102 patients (46 females, 56 males) who underwent pancreatic resection for PanIn. PLR was calculated and quantified using a cutoff of 110, sarcopenia was quantified using the skeletal muscle index (SMI) on preoperative abdominal imaging. Both were co-evaluated with additional demographic, clinical, pathological, and imaging data for possible correlation with PanIN associated PDAC. RESULTS: PLR was significantly elevated in patients with PanIN - associated PDAC (p=0.006). In the multivariate analysis, invasive carcinomas were significantly more prevalent in patients with PLR above 110 (OR=4.06, 95%CI=3.91-4.12, p=0.04). Patients with elevated PLR had a two-times higher risk to die in the postoperative period (HR=2.26, 95%CI=1.04-2.21, p=0.001). Patients with elevated PLR, preoperative jaundice and sarcopenia were the most likely to have PanIN-associated PDAC (OR=3.48, 95%CI=2.98-8.41, p=0.02). CONCLUSION: PLR is an independent predictive marker for the presence of PanIN associated invasive carcinoma.

RESUMO

INTRODUCTION: Liver metastases originating from various types of sarcoma are a rare reason for hepatic resection. So far, even multicentre studies do hardly provide statistically relevant sample sizes. Thus, review of available data can provide surgeons with useful information in similar cases. Therefore, this study can be regarded more as a contribution to this pool of data than as a stand-alone paper. PATIENTS AND METHODS: The study includes 10 women and five men who underwent subtotal hepatic resection for solitary (n = 4) and multiple (n = 11) liver metastases originating from sarcoma. The median tumour diameter was 60 mm (range 20-200 mm). RESULTS: Morbidity was 33%. One patient died within 30 days after surgery. Resection was complete (R0) in 67%. Median overall survival was 33.6 months, 5-year survival 27%. The use of Pringle manoeuvre was significantly associated with poorer outcome (p = 0.014) and shorter period of recurrence-free survival (p = 0.012). Diameter of liver lesion over 50 mm showed significantly shorter recurrence-free survival (p = 0.042). CONCLUSION: Hepatic resection may be beneficial in patients with isolated sarcoma metastasis in the liver.

RESUMO

Hamartomas of the spleen are rare benign tumour-like lesions that tend to be asymptomatic incidental findings. Splenic hamartomas with tumour-like extramedullary erythropoiesis are extremely rare. A 70-year-old male patient with dyspnoea and a nodular intrapulmonary lesion morphologically verified by CT underwent fibre bronchoscopy, which showed a pea-shaped foreign body that was retrieved without complication. As a secondary finding, the CT showed a splenic lesion of about 8 cm in size. An MR study showed an expansive process in the center of the spleen. The patient was completely free of clinical symptoms. Because of the unknown nature and the high risk for spontaneous rupture of the lesion, a splenectomy was performed. The histological analyses revealed tumour-like extramedullary erythropoiesis of the spleen. The patient was discharged in good condition ten days postoperatively. A hamartoma of the spleen with extramedullary tumor-like erythropoiesis should be considered in the differential diagnosis of a splenic lesion.

RESUMO

BACKGROUND: We conducted a survey to determine whether hernia surgeons follow evidence-based medicine (EBM) criteria in their daily routine. METHODS: All chiefs of general surgery in Styria (Austria) received a short, simple, two-page, 10-item questionnaire. RESULTS: We analyzed completed surveys from 15 departments reporting 2441 hernia repairs with a mean patient age of 57.5 +/- 11.6 years. Although five techniques accounted for 96.6% of procedures, the frequency of use of each technique varied considerably among the hospitals. There were high numbers of laparoscopic (36.8%) and sutured (19.9%) repairs. CONCLUSIONS: Because of the great variance among the evaluated hospitals as to surgical methods and indications, this survey showed that inguinal hernia surgery does not currently comply with EBM.

RESUMO

BACKGROUND: Increasing concern has been expressed worldwide on the problem of finding young doctors to enter a training programme in an operative speciality. MATERIALS AND METHODS: A survey comprising 22 questions on working conditions and job satisfaction was placed on the homepage of the Austrian Society of Surgery; 667 questionnaires were completed. RESULTS: The question whether surgery is threatened by a trainee shortage was answered with "yes" by 68%. Only 37% were satisfied with their working conditions. The majority (61%) specified documentation as making up between 20% and 40% of their workload, 22.5% estimated an even higher percentage. Only 17.7% were satisfied with payment. A clear majority works 60 to 80 h per week or more. Only 32.5% stated that they can leave the hospital in the morning after weekend duty; for night duty during the week, this percentage decreased to just 4.2%. As for surgical training, 33.3% were satisfied. Regular assessments between the trainees and their department heads were confirmed by only 34%. A clear majority (96%) is in favour of rotations in other hospitals during residency for the sake of broader experience. CONCLUSION: Working hour restrictions are essential, but not enough: Substantial improvements in the professional profile and in training are required.

RESUMO

BACKGROUND/AIM: Prognostic factors like the CRP-to-albumin ratio (CAR) represent potential predictors for survival of pancreatic cancer patients. We aimed to investigate the prognostic strength of the CAR for overall survival of patients with pancreatic cancer undergoing pancreatic resection. PATIENTS AND METHODS: Data from a total of 202 patients with pancreatic adenocarcinoma who had undergone curative pancreatic resection were subjected to a retrospective review. Overall survival was calculated according to the Kaplan-Meier method, and multivariate Cox regression analysis was used for calculating the prognostic strength of CAR. RESULTS: CAR was an independent prognostic factor of overall survival in univariate and multivariate Cox regression analysis. Elevated CAR was associated with a higher median value of Charlson Index, higher Union for International Cancer Control (UICC) classification and increased carcinoembryonic antigen (CEA) levels. CONCLUSION: CAR is a useful prognostic factor for the prediction of overall survival for patients undergoing pancreatic surgery. The impact of CAR in individual risk assessment should be evaluated in further studies.

RESUMO

BACKGROUND/AIM: The liver is a frequent site for metastases of colorectal cancer. Approximately 15% of patients have hepatic metastases at the time of diagnosis and another 50% develop them over the course of their disease. Only 10-25% of patients are candidates for liver resection. The aim of this study was to assess the benefit of preoperative computed tomography (CT)-guided wire marking of disappearing colorectal liver metastases (CRLMs) (radiological disappearance of metastases) before surgical resection. PATIENTS AND METHODS: Between January 2011 and January 2014, 20 patients with potentially disappearing CRLMs were selected for CT-guided wire marking. Following treatment with neoadjuvant chemotherapy, disappearing CRLMs were marked via CT guidance. Afterwards, the marked sites were resected. RESULTS: Complete histological response to neoadjuvant chemotherapy was only in 10 resected sites (18%), and 46 (82%) resected liver metastases showed metastatic tissue present. Both overall survival and the disease-free rates in patients after using our method were 55%. CONCLUSION: This study demonstrated the usefulness of CT-guided wire marking to mark disappearing CRLMs in order to improve long-term effectiveness of surgical treatment.

RESUMO

BACKGROUND & AIM: Primary hepatic angiosarcoma is a rare tumor with poor prognosis. The aim of this study was to generate a new angiosarcoma model to improve research on hepatic angiosarcoma. METHODS: Pigs sus scrofa were treated with different regimens of diethylnitrosamine (DENA). Tissues were analyzed by histology and immunohistochemistry. Serum parameters were determined. Angiosarcoma tissue was investigated for chromosomal aberrations by aCGH analysis. RESULTS: Animals of almost all different treatment regimens developed a multitude of variable liver lesions. Different tumor types such as granulation tissue type, cellular-like, hyalinization necrosis-like, angiosarcoma-like, dysplastic nodule-like, hepatocellular-like, glandular structure-like, and leiomyoma-like lesions were observed. Weekly treatment with 15 mg/kg for up to 52 weeks or a single shot of 200 mg/kg DENA led to the development of hepatic angiosarcomas. aCGH analysis of angiosarcoma tissue revealed increased alterations in tumors compared to non-tumorous tissue. Most of the chromosomal alterations were found on chromosomes 6, 7, 12, and 14. CONCLUSION: In this preliminary study treatment of sus scrofa with weekly injections of 15 mg/kg DENA results in a new model for primary hepatic angiosarcoma. This model may help to shed light on the pathomechanisms of primary hepatic angiosarcoma and might therefore open new treatment options.

RESUMO

BACKGROUND: Diffuse large B-cell lymphoma is the most common subtype of non-Hodgkin lymphoma with or without involvement of extranodal sites. Rituximab in combination with cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP) therapy represents the current standard therapy, achieving a rather dissatisfying outcome in approximately 30-40% of all cases. CASE PRESENTATION: We present the case of a 43-year-old Austrian woman with an incidentally detected large pelvic mass which was diagnosed as diffuse large B-cell lymphoma. Initially, the lymphoma intraoperatively appeared to be an inoperable conglomerate tumor. Soon, intestinal perforation induced by tumor infiltration occurred, which initiated a closure of the small intestine and application of a jejunal probe and a percutaneous endoscopic gastrotomy tube. Treatment utilizing the gold standard rituximab in combination with cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP) was performed, partly resulting in remission according to radiological follow-up. In view of diagnosis and primary treatment development, the predictive outcome appeared unsound. However, within the procedure of the latest surgical intervention, which was intended to at least reconstruct the intestinal passage in order to improve quality of life, a surgical R0 resection of the residual tumor mass was achieved. CONCLUSIONS: The case presented here reports an unanticipated process of diffuse large B-cell lymphoma, underlining the importance of interdisciplinary cooperation and surgical intervention within the realms of state-of-the-art treatment.
