In patients initially staged as unresectable this may be achieved with neoadjuvant treatment which is usually chemoradiotherapy based. We report the case of a 46-year-old patient with an unresectable, locally advanced pancreatic cancer (pT4 Nx cM0 G2) who was treated with a sequential neoadjuvant chemotherapy regimen consisting of 2 cycles of nab-paclitaxel plus gemcitabine followed by 4 cycles of FOLFIRINOX. Neoadjuvant chemotherapy resulted in secondary resectability (R0 resection). After 2 cycles of nab-paclitaxel plus gemcitabine, the patient already had a complete metabolic remission as measured by integrated fludeoxyglucose ((18)F) positron emission tomography and computerized tomography. After a follow-up of 18 months the patient is alive without progression of disease. We propose to assess the clinical benefit of sequencing the combinations nab-paclitaxel plus gemcitabine and FOLFIRINOX as neoadjuvant therapy for patients with locally advanced and initially unresectable pancreatic cancer in a controlled clinical trial.},

  abstract  = {Purpose Once open abdomen therapy has succeeded, the problem of closing the abdominal wall must be addressed. We present a new four-stage procedure involving the application of a two-component mesh and vacuum conditioning for abdominal wall closure of even large defects. The aim is to prevent the development of a giant ventral hernia and the eventual need for the repair of the abdominal wall. Methods Nineteen of 62 patients treated by open abdomen over a two-year period could not receive primary abdominal wall closure. To achieve closure in these patients, we applied the following four-stage procedure: stage 1: abdominal damage control and conditioning of the abdominal wall; stage 2: attachment of a tailored two-component mesh of polyglycolic acid (PGA) and large pore polypropylene (PP) in intraperitoneal position (IPOM) plus placement of a vacuum bandage; stage 3: vacuum therapy for 3-4 weeks to allow granulation of the mesh and optimization of dermatotraction; stage 4: final skin suture. During stage 3, eligible patients were weaned from respirator and mobilized. Results The abdominal wall gap in the 19 patients ranged in size from 240 cm2 to more than 900 cm2. An average of 3.44 vacuum dressing changes over 19 days were required to achieve 60-100 \% granulation of the surface area, so final skin suture could be made. Already in stage 3, 14 patients (73.68 \%) could be weaned from respirator an average of 6.78 days after placement of the two-component mesh; 6 patients (31.57 \%) could be mobilized on the edge of the bed and/or to a bedside chair after an average of 13 days. No mesh-related hematomas, seromas, or intestinal fistulas were observed. Conclusion The four-stage procedure presented here is a viable option for achieving abdominal wall closure in patients treated with open abdomen, enabling us to avoid the development of planned giant ventral hernias. It has few complications and has the special advantage of allowing mobilization of the patients before final skin closure. Long-term course in a large number of patients must still confirm this result.},

  abstract  = {Volume therapy is a standard procedure in daily perioperative care, and there is an ongoing discussion about the benefits of colloid resuscitation with hydroxyethylstarch (HES). In sepsis HES should be avoided due to a higher risk for acute kidney injury (AKI). Results of the usage of HES in patients without sepsis are controversial. Therefore we conducted an animal study to evaluate the impact of 6\% HES 130/0.4 on kidney integrity with sepsis or under healthy conditions Sepsis was induced by standardized Colon Ascendens Stent Peritonitis (sCASP). sCASP-group as well as control group (C) remained untreated for 24 h. After 18 h sCASP+HES group (sCASP+VOL) and control+HES (C+VOL) received 50 ml/KG balanced 6\% HES (VOL) 130/0.4 over 6h. After 24h kidney function was measured via Inulin- and PAH-Clearance in re-anesthetized rats, and serum urea, creatinine (crea), cystatin C and Neutrophil gelatinase-associated lipocalin (NGAL) as well as histopathology were analysed. In vitro human proximal tubule cells (PTC) were cultured +/- lipopolysaccharid (LPS) and with 0.1-4.0\% VOL. Cell viability was measured with XTT-, cell toxicity with LDH-test. sCASP induced severe septic AKI demonstrated divergent results regarding renal function by clearance or creatinine measure focusing on VOL. Soleley HES (C+VOL) deteriorated renal function without sCASP. Histopathology revealed significantly derangements in all HES groups compared to control. In vitro LPS did not worsen the HES induced reduction of cell viability in PTC cells. For the first time, we demonstrated, that application of 50 ml/KG 6\% HES 130/0.4 over 6 hours induced AKI without inflammation in vivo.

  abstract  = {Background Up to 50\% of septic patients develop acute kidney injury (AKI). The pathomechanism of septic AKI is poorly understood. Therefore, we established an innovative rodent model to characterize sepsis-induced AKI by standardized colon ascendens stent peritonitis (sCASP). The model has a standardized focus of infection, an intensive care set up with monitoring of haemodynamics and oxygenation resulting in predictable impairment of renal function, AKI parameters as well as histopathology scoring. Methods Anaesthetized rats underwent the sCASP procedure, whereas sham animals were sham operated and control animals were just monitored invasively. Haemodynamic variables and blood gases were continuously measured. After 24 h, animals were reanesthetized; cardiac output (CO), inulin and PAH clearances were measured and later on kidneys were harvested; and creatinine, urea, cystatin C and neutrophil gelatinase-associated lipocalin (NGAL) were analysed. Additional sCASP-treated animals were investigated after 3 and 9 days. Results All sCASP-treated animals survived, whilst ubiquitous peritonitis and significantly deteriorated clinical and macrohaemodynamic sepsis signs after 24 h (MAP, CO, heart rate) were obvious. Blood analyses showed increased lactate and IL-6 levels as well as leucopenia. Urine output, inulin and PAH clearance were significantly decreased in sCASP compared to sham and control. Additionally, significant increase in cystatin C and NGAL was detected. Standard parameters like serum creatinine and urea were elevated and sCASP-induced sepsis increased significantly in a time-dependent manner. The renal histopathological score of sCASP-treated animals deteriorated after 3 and 9 days. Conclusions The presented sCASP method is a standardized, reliable and reproducible method to induce septic AKI. The intensive care set up, continuous macrohaemodynamic and gas exchange monitoring, low mortality rate as well as the opportunity of detailed analyses of kidney function and impairments are advantages of this setup. Thus, our described method may serve as a new standard for experimental investigations of septic AKI.},

Methods Data from a prospectively collected single-institutional Center Cancer Registry with 1108 consecutive patients with gastric adenocarcinoma (GC), clinical, histological and survival data were analyzed for independent risk factors and prognosis with focus on the development of metaPC. Findings were then stratified to the time periods of treatment with surgery alone, 5-Fluorouracil-only and contemporary combined systemic perioperative chemotherapy strategies, respectively. Results Despite R0 D2 gastrectomy (n = 560), 49.6\% (±5.4\%) of the patients were diagnosed with tumour recurrence and 15.5\% (±1.8\%) developed metaPC after a median time of 17.7 (15.1-20.3) months after surgery resulting in a tumour related mortality of 100\% with a median survival of 3.0 months (2.1 - 4.0). Independent risk factors for the development of metaPC were serosa positive T-category, nodal positive-status, signet cell and undifferentiated gradings (G3/G4). Contemporary systemic combination chemotherapy did not improve the incidence and prognosis of metaPC (p = 0.54). Conclusions Despite significant improvements in the overall survival for the complete cohort with gastric cancer over time, those patients with metaPC did not experience the same benefits. The lack of change in the incidence, and persistent poor prognosis of metaPC after curative surgery expose the need for further prevention and/or improved treatment options for this devastating condition.},

  abstract  = {Regulatory T cells (Treg) expressing the transcription factor forkhead box protein P3 (Foxp3) have been demonstrated to mediate evasion from anti-tumor immune responses during tumor progression. Moreover, Foxp3 expression by tumor cells themselves may allow them to counteract effector T cell responses, resulting in a survival benefit of the tumor. For gastrointestinal cancers, in particular pancreatic and colorectal cancer (CRC), the clinical relevance of Foxp3 is not clear to date. Therefore the aim of this study was to analyze its impact in CRC and pancreatic cancer. To determine the relevance of Foxp3 for tumor progression and patient survival, gene and protein analysis of human pancreatic and colon cancer cell lines as well as tumor tissues from patients with CRC was performed. The results derived from the patients with CRC were correlated with clinicopathological parameters and patients' overall survival. Cancer cell mediated Foxp3 expression in vitro was demonstrated in human pancreatic cancer cell lines PANC1, PaCa DD 135, PaCa DD 159 and PaCa DD 185 as well as in human colon cancer cell lines SW480 and SW620. Additionally, Foxp3 expressing cancer cells were found in ex vivo tumor tissue samples of patients with CRC. The percentage of Foxp3+ cancer cells increased from stages UICC I/II to UICC III/IV compared to normal tissue. Moreover, high tumor cell mediated Foxp3 expression was associated with poor prognosis compared to patients with low Foxp3 expression. In contrast, low and high Foxp3 level in tumor infiltrating Treg cells demonstrated no significant differences in patients' overall survival. Correlation analysis demonstrated a significant association of Foxp3 cancer cell expression with the expression of immunosuppressive cytokines IL-10 and TGF-β. These findings suggest that Immunosuppressive cytokines such as IL-10 and TGF-β released by rather Foxp3+ cancer cells than Foxp3+ Treg cells may inhibit the activation of naive T cells, hence limiting antitumor immune responses and favoring tumorigenesis and progression. Chronic inflammation has been shown to be an important epigenetic and environmental factor in numerous tumor entities. Recent data suggest that tumorigenesis and tumor progression may be associated with inflammation-triggered activation of Toll-like receptors (TLR). In this study, the specific impact of both TLR7 and TLR8 expression and signaling on tumor cell proliferation and chemoresistance is analyzed in inflammation linked CRC and pancreatic cancer. By gene and protein expression analysis of human pancreatic and colon cancer cell lines TLR7 and TLR8 expression was determined in vitro. Additionally, expression of TLR7/TLR8 in UICC stage I-IV pancreatic cancer, chronic pancreatitis and normal pancreatic tissue was examined. For in vitro/in vivo studies TLR7/TLR8 overexpressing PANC1 cell lines were generated and analyzed for effects of TLR expression and stimulation on tumor cell proliferation and chemoresistance. Cancer cell mediated TLR7 and TLR8 expression in vitro was demonstrated in human colon cancer cell lines SW480, SW620 and HT-29 as well as in primary pancreatic cancer cell lines PaCa DD 135, PaCa DD 159 and PaCa DD 185. Additionally, TLR7 and TLR8 expressing tumor cells were found in ex vivo tissue samples of patients with pancreatic cancer and chronic pancreatitis. Significantly elevated expression levels of TLR7 and TLR8 were found in advanced tumor stages (UICC III) compared to early tumor stages (UICC II) and chronic pancreatitis. No or occasionally low expression was detected in normal pancreatic tissue. In contrast to the tissues from patients with pancreatic cancer or chronic pancreatitis, established pancreatic tumor cell lines express only very low levels of TLR7 and TLR8. Therefore, for in vitro and xenograft studies TLR7 or TLR8 overexpressing PANC1 cells were generated. Proliferation promoting effects of TLR7 and TLR8 expression and stimulation with R848 were detected in vitro. Additionally, increased tumor growth of TLR expressing PANC1 cells was demonstrated in subcutaneously injected Balb/c nude mice. Interestingly, activation of TLR7 or TLR8 induced not only an increase in tumor cell proliferation but also a strong chemoresistance of PANC1 cells against 5-fluorouracil (5-FU). Moreover, treatment with R848 resulted in elevated expression levels of NF-κB, COX-2 and inflammatory cytokines IL-1β, IL-8 and TNF-α, suggesting TLR7/8 signaling to contribute to an inflammatory, anti-apoptotic and proliferation promoting tumor microenvironment. These findings emphasize the particular role of TLR7 and TLR8 in inflammation related cancers and their relevance as potential targets for cancer therapy.  },

  abstract  = {Background Although the repair of ventral abdominal wall hernias is one of the most commonly performed operations, many aspects of their treatment are still under debate or poorly studied. In addition, there is a lack of good definitions and classifications that make the evaluation of studies and meta-analyses in this field of surgery difficult. Materials and methods Under the auspices of the board of the European Hernia Society and following the previously published classifications on inguinal and on ventral hernias, a working group was formed to create an online platform for registration and outcome measurement of operations for ventral abdominal wall hernias. Development of such a registry involved reaching agreement about clear definitions and classifications on patient variables, surgical procedures and mesh materials used, as well as outcome parameters. The EuraHS working group (European registry for abdominal wall hernias) comprised of a multinational European expert panel with specific interest in abdominal wall hernias. Over five working group meetings, consensus was reached on definitions for the data to be recorded in the registry. Results A set of well-described definitions was made. The previously reported EHS classifications of hernias will be used. Risk factors for recurrences and co-morbidities of patients were listed. A new severity of comorbidity score was defined. Post-operative complications were classified according to existing classifications as described for other fields of surgery. A new 3-dimensional numerical quality-of-life score, EuraHS-QoL score, was defined. An online platform is created based on the definitions and classifications, which can be used by individual surgeons, surgical teams or for multicentre studies. A EuraHS website is constructed with easy access to all the definitions, classifications and results from the database. Conclusion An online platform for registration and outcome measurement of abdominal wall hernia repairs with clear definitions and classifications is offered to the surgical community. It is hoped that this registry could lead to better evidence-based guidelines for treatment of abdominal wall hernias based on hernia variables, patient variables, available hernia repair materials and techniques.},

  abstract  = {Purpose Once open abdomen therapy has succeeded, the problem of closing the abdominal wall must be addressed. We present a new four-stage procedure involving the application of a two-component mesh and vacuum conditioning for abdominal wall closure of even large defects. The aim is to prevent the development of a giant ventral hernia and the eventual need for the repair of the abdominal wall. Methods Nineteen of 62 patients treated by open abdomen over a two-year period could not receive primary abdominal wall closure. To achieve closure in these patients, we applied the following four-stage procedure: stage 1: abdominal damage control and conditioning of the abdominal wall; stage 2: attachment of a tailored two-component mesh of polyglycolic acid (PGA) and large pore polypropylene (PP) in intraperitoneal position (IPOM) plus placement of a vacuum bandage; stage 3: vacuum therapy for 3-4 weeks to allow granulation of the mesh and optimization of dermatotraction; stage 4: final skin suture. During stage 3, eligible patients were weaned from respirator and mobilized. Results The abdominal wall gap in the 19 patients ranged in size from 240 cm2 to more than 900 cm2. An average of 3.44 vacuum dressing changes over 19 days were required to achieve 60-100 \% granulation of the surface area, so final skin suture could be made. Already in stage 3, 14 patients (73.68 \%) could be weaned from respirator an average of 6.78 days after placement of the two-component mesh; 6 patients (31.57 \%) could be mobilized on the edge of the bed and/or to a bedside chair after an average of 13 days. No mesh-related hematomas, seromas, or intestinal fistulas were observed. Conclusion The four-stage procedure presented here is a viable option for achieving abdominal wall closure in patients treated with open abdomen, enabling us to avoid the development of planned giant ventral hernias. It has few complications and has the special advantage of allowing mobilization of the patients before final skin closure. Long-term course in a large number of patients must still confirm this result.},

  abstract  = {Objective: To determine whether rats reaching the same body mass, having been fed either a low-fat (LFD) or a high-fat diet (HFD), differ in white adipose tissue (WAT) deposition. Methods: In experiment 1, 22 Sprague-Dawley rats of the same age were divided into 11 rats with body mass below the batch median and fed a HFD, and 11 above the median and fed a LFD. In experiment 2, 20 Sprague-Dawley rats of the same age and starting body mass were randomised to either a HFD or LFD. When all groups reached similar final body mass, WAT was quantified using magnetic resonance imaging (MRI), dissection, and plasma leptin. Results: In experiment 1, both groups reached similar final body mass at the same age; in experiment 2 the HFD group reached similar final body mass earlier than the LFD group. There were no significant differences in WAT as assessed by MRI or leptin between the HFD and LFD groups in both experiments. Dissection revealed a trend for higher retroperitoneal and epididymal adiposity in the HFD groups in both experiments. Conclusions: We conclude that at similar body mass, adiposity is independent of the macronutrient composition of the feeding regimen used to achieve it. (C) 2014 S Karger GmbH, Freiburg},

Eine Abh{\"a}ngigkeit zwischen Alter und Majornachamputationsrate konnte nicht festgestellt werden, jedoch eine Tendenz beim Einfluss von Comorbidit{\"a}ten wie Diabetes mellitus und dialysepflichtiger Niereninsuffizienz auf die Wundheilung und Liegedauer. Die Anzahl an durchgef{\"u}hrten gef{\"a}ßchirurgischen Eingriffen wie PTA und Bypass-Operation lag in beiden Gruppen mit 65\% bzw. 72\% im Vergleich zur Literatur im Standardbereich. Eine hohe Rate an gef{\"a}ßmedizinischer Diagnostik und Therapie scheint auch bei fortgeschrittener pAVK (Grad IV) erforderlich, um die Notwendigkeit von Amputationen insbesondere die Anzahl an Majoramputationen zu verringern. Bei hoher und mit Gruppe 1 vergleichbarer Interventionsrate in Gruppe 2 l{\"a}sst sich allerdings auch erkennen, dass trotz Aussch{\"o}pfung dieser Massnahmen die Rate an Majoramputationen und damit des Beinverlustes hoch ist. Positiv zu werten ist, dass es bei {\"u}ber 50\% der Amputierten ausgereicht hat, eine Amputation im Fussbereich (Minoramputation) durchzuf{\"u}hren. Bei diesen 63 Patienten, war bei 58 Patienten sogar nur ein Eingriff n{\"o}tig. Ferner handelte es sich bei den Majoramputationen in der Mehrzahl um Unterschenkelamputation, und somit um einen nur partiellen Beinverlust . 76\% der durchgef{\"u}hrten ersten Majoramputationen erfolgten in den ersten beiden Monaten nach vorausgegangener Minoramputation, die gr{\"o}ßte Anzahl innerhalb des ersten Monats. Auch die letzte Amputation, die definitive Versorgung, erfolgte in den meisten F{\"a}llen innerhalb der ersten beiden Monate nach Prim{\"a}reingriff. Somit ist ein nur unwesentlicher Aufschub bis zur definitiven Versorgung ersichtlich. Der Versuch einer Konsolidierung der Isch{\"a}miefolgen (Gangr{\"a}n) mittels Minoramputation scheint bei fortgeschrittener pAVK im Stadium IV nach Aussch{\"o}pfung der gef{\"a}ßmedizinischen Diagnostika und Interventionen somit immer gerechtfertigt, und sollte wenn m{\"o}glich einer Majoramputation vorgezogen werden. Die durchschnittliche Krankenhausverweildauer in der Gruppe der Minoramputationen lag bei 28 Tagen, in der Gruppe 2 der Majoramputationen bei 39 Tagen. Die Mortalit{\"a}tsrate ergibt einen deutlich erh{\"o}hten Wert in der Gruppe der Majoramputationen. Die Dreijahresmortalit{\"a}t betrug in der Gruppe der Minoramputationen 20\% und der Majoramputationen 58\%. Es zeigte sich eine Zunahme der Mortalit{\"a}t mit zunehmender Amputationsh{\"o}he und zunehmender Zahl der Amputationen. Diese Daten lassen sich mit 52 aktuellen Literaturangaben durchaus vergleichen und beweisen die schlechte Prognose f{\"u}r AVK-Patienten, bei denen eine Majoramputation unausweichlich ist. Insgesamt ist es wichtig, dass ein Team aus Chirurgen, Gef{\"a}ßchirurgen, Radiologen und Angiologen kooperativ zusammen arbeitet, um dem Patienten, eine f{\"u}r ihn beste Versorgung anbieten zu k{\"o}nnen. Hier sollte auch nicht vor einem oft h{\"o}heren Patientenalter zur{\"u}ckgeschreckt werden, denn h{\"a}ufig konnte gerade bei diesen Patienten durch eine Bypass-Operation eine sonst vermutlich unumg{\"a}ngliche Amputation im Unter- bzw. Oberschenkelbereich verhindert werden.},

  abstract  = {Clinical prognosis of metastasized colorectal carcinoma (CRC) is still not at desired levels and novel drugs are needed. Here, we focused on the multi-tyrosine kinase inhibitor E7080 (Lenvatinib) and assessed its therapeutic efficacy against human CRC cell lines in vitro and human CRC xenografts in vivo. The effect of E7080 on cell viability was examined on 10 humanCRCcell lines and humanendothelial cells (HUVEC). The inhibitory effect of E7080 on VEGF-induced angiogenesis was studied in an ex vivo mouse aortic ring angiogenesis assay. In addition, the efficacy of E7080 against xenografts derived fromCRC cell lines and CRC patient resection specimenswithmutated KRASwas investigated in vivo. Arelatively low cytotoxic effect of E7080 on CRC cell viabilitywas observed in vitro. Endothelial cells (HUVEC)weremore susceptible to the incubation with E7080. This is in line with the observation that E7080 demonstrated an anti-angiogenic effect in a three-dimensional ex vivo mouse aortic ring angiogenesis assay. E7080 effectively disrupted CRC cell-mediated VEGF-stimulated growth of HUVEC in vitro. Daily in vivo treatment with E7080 (5 mg/kg) significantly delayed the growth of KRAS mutated CRC xenografts with decreased density of tumor-associated vessel formations and without tumor regression. This observation is in line with results that E7080 did not significantly reduce the number of Ki67-positive cells in CRC xenografts. The results suggest antiangiogenic activity of E7080 at a dosage thatwas well tolerated by nudemice. E7080 may provide therapeutic benefits in the treatment of CRC with mutated KRAS.},

In der vorliegenden Arbeit wurden Dendritische Zellen aus Milzen von M{\"a}usen verschiedener Linien mit¬tels Dichtegradientenzentrifugation unter Verwendung von OptiPrep (Iodixanol) isoliert und ph{\"a}notypisch sowie funktionell charakterisiert. Die gewonnenen Zellsuspensionen bestanden durchschnittlich zu 41 Prozent aus residenten konventionellen Dendritischen Zellen. Die isolierten Dendritischen Zellen waren unabh{\"a}ngig von der untersuchten Mauslinie bis zu 26 Prozent CD8α-positiv und bis zu 81 Prozent CD8α-negativ. Dendritische Zellen wiesen unmittelbar nach der Zellgewinnung einen unreifen Ph{\"a}notyp auf mit starker Expression von MHC-Klasse-II, aber schwacher bis fehlender Expression der kostimulato¬rischen Molek{\"u}le CD80, CD86 und CD40. Eine 24- bzw. 48-st{\"u}ndige Kulti¬vierung in vitro f{\"u}hrte zur Reifung der Dendritischen Zellen mit Zunahme der Expression von MHC-Klasse-II, CD80, CD86 und CD40 um den Faktor 2 bis 4. Diese Zellen wiesen zudem immunstimulatorische Eigenschaften in der gemischten (allogenen) Leukozytenkultur auf. Dendritische Zellen der Mauslinie NMRInude exprimierten nach der In-vitro-Kultur ebenfalls zahlreiche Ober¬fl{\"a}chenmarker, darunter die Reifungsmarker. Die St{\"a}rke der Expression war jedoch um bis zu 50 Prozent schw{\"a}cher als bei Dendritischen Zellen der anderen Mauslinien. Dieser Befund weist auf potentielle Unterschiede zwischen Dendritischen Zellen der thymuslosen Mauslinie NMRInude und Dendritischen Zellen von Wildtyp-M{\"a}usen hin. Es wurde gezeigt, dass OptiPrep zur Isolierung Dendritischer Zellen aus M{\"a}usemilzen bei geringem Arbeitsaufwand und niedrigen Kosten verwendet werden kann.

  abstract  = {Einleitung: Eine pr{\"a}operative Selektion adip{\"o}ser Patienten anhand objektiver Kriterien soll entscheidend sein f{\"u}r den Gewichtsverlauf nach Implantation eines Magenbandes (Laparoscopic adjustable gastric banding, LAGB). Es ist unbekannt, ob die pr{\"a}operative Selektion Auswirkungen auf das Langzeitergebnis des LAGB hat. Material und Methoden: Die vorliegende Studie suchte nach objektiven Variablen mit signifikanter Vorhersagekraft f{\"u}r das Langzeitergebnis des LAGB. Hierf{\"u}r wurde der Gewichtsverlauf nach LAGB in einem j{\"a}hrlichen Intervall analysiert. 166 Patienten (91,2 \%) nahmen an der retrospektiven Studie teil (Lost to Follow-up 8,8 \%). Das mediane Follow-up des gesamten Patientenguts betrug 83,1 Monate (Range 0,1 - 177,3 Monate) und endete am Tag des abschließenden Interviews mit den Studienteilnehmern, jedoch sp{\"a}testens bei ersatzloser Explantation des Magenbandes (Studienende). Eine Per-Protokoll-Analyse untersuchte den Gewichtsverlauf von Patienten ohne ersatzlose Explantation des Magenbandes (N = 111). Der prozentuale Verlust an {\"U}bergewicht (Excess Weight Loss, EWL \%) am Studienende entschied {\"u}ber das Langzeitergebnis (Success: EWL ≥ 50,0 \% mit LAGB, No Success: EWL < 50,0 \% mit LAGB oder ersatzlose Explantation des LAGB; Failure: EWL < 20,0 \% mit LAGB oder ersatzlose Explantation des LAGB, No Failure: EWL ≥ 20,0 \% mit LAGB). Zur Absch{\"a}tzung von pr{\"a}diktiven Faktoren hinsichtlich der abh{\"a}ngigen Variablen Success und No Success sowie Failure und No Failure wurde eine bin{\"a}r logistische Regressionsanalyse durchgef{\"u}hrt. Folgende pr{\"a}operative Kovariaten wurden auf ihren pr{\"a}diktiven Langzeiteffekt analysiert: Alter, Body-Mass-Index, {\"U}bergewicht (Excess Weight), Geschlecht, Adipositas assoziierte Komorbidit{\"a}ten (Diabetes Mellitus Typ II, arterieller Hypertonus, Schlafapnoe, Gelenkbeschwerden, Belastungsdyspnoe), Bandart (Swedish adjustable gastric banding, Lap Band), Operationstechnik (Pars flaccida, retrogastrisch). Ergebnisse: In der vorliegenden Studie war der EWL (\%) im Langzeitverlauf moderat. Der h{\"o}chste mediane EWL (\%) des gesamten Patientenguts wurde im 2. postoperativen Jahr erreicht und betrug 43,2 \% (Range -34,1 - 178,8 \%) (N = 155). Mit zunehmendem Follow-up sank der EWL (\%). Im 5.-, 10.- und 14. postoperativen Jahr betrugen der mediane EWL 39,7 \% (Range -39,7 - 162,0 \%) (N = 126), 31,0 \% (Range -37,6 - 139,7 \%) (N = 65) und 31,9 \% (Range -34,0 - 108,6 \%) (N = 27). Am Studienende wurde am h{\"a}ufigsten ein EWL-Level von 30 - 40 \% (12 \%, N = 20) erreicht. Pr{\"u}fkonforme Patienten erreichten am Studienende einen medianen EWL von 33,2 \% (Range -81,4 - 116,7 \%) (N = 111). Wie bereits in der Literatur berichtet nahmen mit zunehmendem Follow-up die Anteile an Success und No Failure ab. Im 2. postoperativen Jahr betrugen die Success- und No Success-Raten 38,0 \% und 62,0 \% (Failure: 24,7 \%, No-Failure: 75,3 \%). Bis zum 10. postoperativen Jahr reduzierte sich der Success-Anteil auf 17,2 \% und der No Success-Anteil stieg auf 82,8 \% (Failure: 60,9 \%, No Failure: 39,1 \%). Am Studienende erf{\"u}llten 18,7 \% (N = 31) der Patienten das Kriterium Success und 81,3 \% (N = 135) das Kriterium No Success (Failure: 52,4 \%, N = 87; No Failure: 47,6 \%, N = 79). Die postoperative Komplikationsrate war hoch, jedoch vergleichbar mit aktuellen Langzeitstudien: 47,6 \% (N = 79) der Patienten entwickelten postoperativ eine oder mehrere Band-assoziierte Komplikationen. Slippage (20,5 \%, N = 34), Pouchdilatation (20,5 \%, N = 34) und Portdislokation/Portdiskonnektion (12,7 \%, N = 21) traten am h{\"a}ufigsten auf. 33,1 \% (N = 55) der Magenb{\"a}nder wurden ersatzlos entfernt nach einer medianen Zeit von 40,7 Monaten (Range 0,1 - 163,6 Monate). Diese Studie belegte die positiven Langzeiteffekte des LAGB auf Adipositas-assoziierte Komorbidit{\"a}ten: 79,4 \% (N = 54) der pr{\"a}operativ hypertonen Patienten und 72,0 \% (N = 18) der Patienten mit initialem Diabetes Mellitus Typ II erreichten am Studienende eine Remission und Heilung (Reduktion und Absetzen der Antihypertensiva bzw. Antidiabetika) ihrer Komorbidit{\"a}t. In der Regressionsanalyse fanden sich keine objektiv fassbaren Parameter, die pr{\"a}operativ ein erfolgreiches Langzeitergebnis nach Implantation eines Magenbandes vorhersagen konnten. Die wichtige pr{\"a}operative Selektion der Patienten wird dadurch erschwert und basiert somit weiterhin auf eher subjektiven Parametern wie Eindruck der Patienten-Compliance, des patientenseitigen Verstehens der Prozedur sowie Patientenwunsch. LAGB ist heute kein bariatrischer Eingriff der ersten Wahl. Jedoch gibt es Patienten, die aufgrund der potentiellen Reversibilit{\"a}t und geringen Mortalit{\"a}t ein LAGB bevorzugen. Wird heute ein LAGB durchgef{\"u}hrt, erscheint auf Basis der klinischen Erfahrung eine engmaschige Anbindung der Patienten in der postoperativen Nachsorge notwendig, um ein optimales Ergebnis zu erreichen. Bei Versagen des Verfahrens (nicht zufriedenstellender Gewichtsverlauf und/oder Auftreten von Band-assoziierten Komplikationen) sind die Entfernung des Magenbandes und die Umwandlung in ein alternatives adipositaschirurgisches Verfahren zumindest zu diskutieren.},

  abstract  = {Background The management of rectal cancer (RC) has substantially changed over the last decades with the implementation of neoadjuvant chemoradiotherapy, adjuvant therapy and improved surgery such as total mesorectal excision (TME). It remains unclear in which way these approaches overall influenced the rate of local recurrence and overall survival. Methods Clinical, histological and survival data of 658 out of 662 consecutive patients with RC were analyzed for treatment and prognostic factors from a prospectively expanded single-institutional database. Findings were then stratified according to time of diagnosis in patient groups treated between 1993 and 2001 and 2002 and 2010. Results The study population included 658 consecutive patients with rectal cancer between 1993 and 2010. Follow up data was available for 99.6\% of all 662 treated patients. During the time period between 2002 and 2010 significantly more patients underwent neoadjuvant chemoradiotherapy (17.6\% vs. 60\%) and adjuvant chemotherapy (37.9\% vs. 58.4\%). Also, the rate of reported TME during surgery increased. The rate of local or distant metastasis decreased over time, and tumor related 5-year survival increased significantly with from 60\% to 79\%. Conclusion In our study population, the implementation of treatment changes over the last decade improved the patient's outcome significantly. Improvements were most evident for UICC stage III rectal cancer.},
