Background: In times of critical organ shortage, poor organ pool utilization and increased use of extended‐criteria donor (ECD) allografts remain a major problem. Hypothermic oxygenated machine perfusion (HOPE) has emerged as a promising and feasible strategy in ECD liver transplantation (LT). However, potential safety limits regarding the duration of perfusion are yet to be explored. Besides marginal allograft quality (steatosis), prolonged cold ischemia time remains the most important factor for a high number of liver allografts being declined for transplantation. Patients and Methods: Two ECD‐allografts were each allocated to two recipients, who proved to be unsuitable to receive the assigned allograft upon arrival at the transplant center. The organs were reallocated by Eurotransplant and accepted by our center for two different backup patients. During that time, HOPE was commenced and continued until the recipient hepatectomy was completed. Postoperative allograft function was assessed by serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, and International Normalized Ratio. Incidence of early allograft dysfunction (EAD), postoperative complications, and length of hospital stay were analyzed. Results: HOPE was applied for 4 h 35 min and 4 h 20 min, resulting in a total cold preservation time of 17 h 29 min and 15 h 20 min, respectively. Both recipients displayed decreasing serum transaminases and bilirubin levels postoperatively. No EAD or major postoperative complications occurred in either patient. Serum ALT and AST levels were within the normal range at discharge. Conclusions: Extended HOPE enables the safe extension of preservation time for up to 18 h in human LT. End‐ischemic HOPE may significantly improve organ pool utilization, while simultaneously facilitating operating room logistics and preventing organ injury. [ABSTRACT FROM AUTHOR]

Background:: Bariatric surgery is currently the most effective method to ameliorate co-morbidities as consequence of morbidly obese patients with BMI over 35 kg/m2. Endoscopic techniques have been developed to treat patients with mild obesity and ameliorate comorbidities, but endoscopic skills are needed, beside the costs of the devices., Aim:: To report a new technique for internal gastric plication using an intragastric single port device in an experimental swine model., Methods:: Twenty experiments using fresh pig cadaver stomachs in a laparoscopic trainer were performed. The procedure was performed as follow in ten pigs: 1) volume measure; 2) insufflation of the stomach with CO2; 3) extroversion of the stomach through the simulator and installation of the single port device (Gelpoint Applied Mini) through a gastrotomy close to the pylorus; 4) performance of four intragastric handsewn 4-point sutures with Prolene 2-0, from the gastric fundus to the antrum; 5) after the performance, the residual volume was measured. Sleeve gastrectomy was also performed in further ten pigs and pre- and post-procedure gastric volume were measured., Results:: The internal gastric plication technique was performed successfully in the ten swine experiments. The mean procedure time was 27±4 min. It produced a reduction of gastric volume of a mean of 51%, and sleeve gastrectomy, a mean of 90% in this swine model., Conclusion:: The internal gastric plication technique using an intragastric single port device required few skills to perform, had low operative time and achieved good reduction (51%) of gastric volume in an in vitro experimental model., Racional:: A cirurgia bariátrica é atualmente o método mais efetivo para melhorar as co-morbidades decorrentes da obesidade mórbida com IMC acima de 35 kg/m2. Técnicas endoscópicas foram desenvolvidas para tratar pacientes com obesidade leve e melhorar as comorbidades, mas habilidades endoscópicas são necessárias, além dos custos., Objetivo:: Relatar uma nova técnica para a plicatura gástrica interna utilizando um dispositivo intragástrico de portal único em modelo experimental de suínos., Métodos:: Foram realizados 20 experimentos utilizando estômagos de cadáver de porco fresco em um instrutor laparoscópico. O procedimento foi realizado da seguinte forma em dez porcos: 1) medida de volume; 2) insuflação do estômago com CO2; 3) extroversão do estômago através do simulador e instalação do dispositivo de uma única via (Gelpoint Applied Mini) através de uma gastrotomia próxima ao piloro; 4) realização de quatro suturas de quatro pontos intra-gástricas com Prolene 2-0, desde o fundo gástrico até o antro; 5) medição do volume residual. A gastrectomia vertical foi também realizada em mais dez suínos e o volume gástrico pré e pós-procedimento foi medido., Resultados:: A técnica de plicatura gástrica interna foi realizada com sucesso nos dez experimentos com suínos. O tempo médio do procedimento foi de 27±4 min. Produziu redução do volume gástrico em média de 51%, e a gastrectomia vertical em média de 90% neste modelo suíno., Conclusão:: A técnica de plicatura gástrica interna, utilizando um dispositivo intragástrico de uma única via, exigiu poucas habilidades para ser realizada, teve baixo tempo operatório e obteve boa redução (51%) do volume gástrico em um modelo experimental in vitro.

Background: The role of radical pancreatic surgery for metastatic lesions of renal cell carcinoma (RCC) remains unclear., Patients and Methods: In this analysis, 19 patients underwent pancreatic resections for metastases of RCC between 2000 and 2014., Results: Pancreatic metastases were diagnosed 10.2±27.1 years after primary diagnosis of RCC. Surgical approaches included pylorus preserving pancreatoduodenectomy (PPPD) (n=10, 55.6%), followed by distal pancreatectomy (n=5, 27.8%) and total pancreatectomy (n=4, 22.2%). The survival after 1, 3 and 5 years was 88.9%, 80% and 71.4%, respectively. Patients after PPPD procedure had a significant worse survival (p=0.030). RCC stage VI tumors seem to be associated with decreased short- and long-term survival rates (p=0.03). Additional metastatic lesions in the further postoperative course had no impact on outcome., Conclusion: The results of our analysis demonstrate promising long-term results with regard to disease-free and overall survival after surgical therapy for pancreatic metastases of renal cell carcinoma., (Copyright© 2016 International Institute of Anticancer Research (Dr. John G.

Background: Incisional hernia after liver transplantation is a common complication with an incidence between 5% and 34%. This prospective study analyzed risk factors, surgical management and long-term results after hernia repair., Material and Methods: From February 2002 until August 2009, 810 liver transplantations were performed. 77 patients (9.5%) underwent incisional hernia repair after a median time of 21.1 months (4.6-76.7) following transplant. These patients were compared to patients without hernia (n=733)., Results: No statistically significant differences between the groups were observed with respect to gender, underlying liver disease, Child-Pugh classification, MELD-Score and preoperative renal failure (p=NS). Multivariate analysis revealed advanced age (p=0.014), body mass index (p=0.016), and re-laparotomies (p<0.001) as independent risk factors for incisional hernias. Pre-existing diabetes mellitus and immunosuppression with mycophenolate mofetil reached significance only in the univariate analysis (p<0.001). Recurrent hernia was observed in 12 of 77 patients (15.6%) at a median time of 7.9 months (4.8-46.8) after primary surgical repair. The recurrence rate after intraperitoneal onlay mesh implantation was lower compared to other mesh techniques (7.7% vs. 21.4%)., Conclusions: The risk factors for the development of incisional hernias in liver transplant patients are similar to patients with prior abdominal surgery for other reasons. Intraperitoneal onlay mesh implantation may lead to a decrease of hernia recurrences. The role of immunosuppression in the genesis of incisional hernias requires further elucidation.

Background: Given the current organ shortage, an accurate assessment of the patient's outcome after orthotopic liver transplantation (OLTX) for fulminant hepatic failure (FHF) is crucial in order to determine the suitability for transplantation. The purpose of this study was to assess whether APACHE II and III scores would provide prognosis of posttransplant mortality., Material/methods: The study included 129 patients with FHF who underwent OLTX between 1988 and 2008. APACHE II and III scores were calculated one day before transplantation and correlated with postoperative mortality. The cohort consisted of 42 males and 87 females with a mean age of 32 ± 17 years., Results: Gender, age and etiology of FHF did not correlate with posttransplant survival (p=NS). The APACHE II score was not significantly higher amongst 30-day non-survivors (p = NS). Both patients who died during this period had a significantly higher APACHE III score compared to survivors (82 ± 19.4 vs. 62 ± 18, p<0.01). Patients with an APACHE III score > 68 had a significantly higher mortality rate (p<0.01). Cox regression analysis revealed the APACHE III score as a significant predictor of death (p<0.001). Each additional point in the APACHE III system raises the postoperative mortality by 3.1%., Conclusions: The major advantage of the APACHE III score is that its application and prognostic ability is independent from etiology of FHF. This accurate and reproducible evaluation system could be useful to identify patients with poor outcome.

The widening gap between donated organs and potential recipients waiting for liver transplantation leads towards intensive efforts to increase the availability of liver grafts. This aim can be accomplished by using organs with extended criteria for acceptance like advanced age, steatosis or donation after cardiac death with prolonged warm ischemic time. Far less frequently, but also worthwhile considering as a valuable source for donor organs is the possibility to reuse organs in case of brain death after orthotopic liver transplantation (OLT). In this case the first organ recipient has to be evaluated to become a potential organ donor for a second recipient. , In our study we report on a case in which we reused a liver graft 24 hours after the first transplantation and present the successful endoscopic management of biliary obstruction.,

Context: The development of pancreatic tissue outside the confines of the main gland represents a congenital abnormality referred to as heterotopic pancreas. This is a rare pathological and surgical entity which remains mostly asymptomatic., Case Report: We present the case of a 28-year-old male, who was admitted to hospital because of a history of blood in bowel movements. After a normal gastroscopy and colonoscopy, Tc99m-tagged red blood cells scintigraphy showed enrichment in the right lower abdomen. At double-balloon endoscopy, a intraluminal polypoid mass 8 cm in diameter was revealed 120 cm from the ileocecal valve. The initial macroscopic diagnosis was a gastrointestinal stromal tumor. During surgery, the diagnosis of heterotopic pancreas with lipoma and fibromatosis was made. To our knowledge this is the first case of ileal heterotopic pancreatic tissue and lipoma described to date in the literature., Conclusion: Ileal heterotopic pancreas is a rare entity with potentially life-threatening complications, local excision being the appropriate indicated treatment.
