Purpose A preoperative estimate of the risk of malignancy for intraductal papillary mucinous neoplasms (IPMN) is important. The present study carries out an external validation of the Shin score in a European multicenter cohort. Methods An observational multicenter European study from 2010 to 2015. All consecutive patients undergoing surgery for IPMN at 35 hospitals with histological-confirmed IPMN were included. Results A total of 567 patients were included. The score was significantly associated with the presence of malignancy (p < 0.001). In all, 64% of the patients with benign IPMN had a Shin score < 3 and 57% of those with a diagnosis of malignancy had a score >= 3. The relative risk (RR) with a Shin score of 3 was 1.37 (95% CI: 1.07-1.77), with a sensitivity of 57.1% and specificity of 64.4%. Conclusion Patients with a Shin score

Textbook outcome (TO) is a composite measure that reflects the most desirable surgical results as a single indicator. The aim of this study was to assess the achievement of TO at a hepatopancreatobiliary (HPB) surgery unit in a Spanish tertiary hospital. Methods: Retrospective observational study of all consecutive patients who underwent HPB surgery over a 4-year period. Morbidity (defined according to the Clavien-Dindo classification) and mortality at 30 days, hospital stay, risk of morbidity and mortality according to the POSSUM scale and readmissions at 90 days were recorded. TO was considered when a patient presented no major complications (³IIIA), no mortality, no readmission, and not prolonged length of stay (LOS: £ 75th percentile of the sample). Results: A total of 283 patients were included (median age: 65 years, 65.4% men). Morbidity >IIIA was reported in 21.6%, and 5.7% died; median postoperative stay was 4 days. TO was achieved in 56.2% of patients. Comparing patients that presented TO with those that did not, significant differences were recorded for the type of procedure and the expected risk of morbidity and mortality calculated according to the POSSUM scale. There were significant differences between patients with major resections (TO rates of 46.3% in major hepatectomy and 52.5% in major pancreatectomy) and those with minor resections (rates of 67.7% in minor hepatectomy and 40.7% in minor pancreatectomy). Conclusion: The rate of TO in our series (56.2%) was like those published internationally. TO is a very useful management tool for assessing postoperative results.

BACKGROUND: Textbook outcome (TO) is a multidimensional quality management tool that uses a set of traditional surgical measures to reflect an "ideal" surgical result for a particular pathology. The aim of the present study is to record the rate of TO in patients undergoing elective surgery for colon cancer. MATERIAL AND METHODS: Retrospective study of all patients undergoing scheduled colon cancer surgery at a Spanish university hospital from September 2012 to August 2016. Patients with rectal cancer were excluded. The variables included in the definition of TO were: R0 resection, number of isolated nodes ≥12, no Clavien-Dindo ≥IIIa complications, no prolonged stay, no readmissions, and no mortality in the first 30 days. RESULTS: Five hundred and sixty-four patients were included in the study. TO was achieved in 49.8%. The sample had a mean age of 69 ± 11 years, and 60% were male. Female sex (OR 1.61; 95% CI 2.30-1.13), T3 and T4 classification (OR 2.50, 95% CI 4.59-1.36, and OR 2.55, 95% CI 5.21-1.24 respectively) and laparoscopic approach (OR 1.53, 95% CI 2.33-1.00) were independent factors that were significantly associated with achieving a TO. Patients who achieved TO had higher overall survival (p=0.008) than those who did not. However, with regard to disease-free survival, no statistically significant differences were found (p=0.303). CONCLUSION: TO is a useful, easy-to-interpret management tool for measuring oncological results and for predicting patient survival. The study was registered in the public accessible database clinicaltrials.gov with the ClinicalTrials.gov ID: NCT05675904. Public release date: 01/05/2023.

Graphical Abstract fx1, Resumen español Introducción: La pandemia COVID-19 ha tenido una repercusión extraordinaria sobre los hospitales españoles, que han reorganizado sus recursos para tratar a estos pacientes, limitando su capacidad de atender otras patologías frecuentes. El presente estudio analiza la repercusión sobre el tratamiento de la colelitiasis y la colecistitis aguda. Métodos: Se ha realizado un estudio nacional descriptivo mediante una encuesta online voluntaria, realizada en Google Drive™, distribuida por correo electrónico desde la Asociación Española de Cirujanos (AEC) a todos los cirujanos miembros. Resultados: Se han recibido 153 encuestas (una por centro). El 96.7% de ellos han suspendido las colecistectomías electivas. El tratamiento conservador de la colecistitis aguda no complicada se ha realizado en un 90% de los casos (siendo previamente del 18%) y, en las colecistitis intervenidas, el 95% ha optado por abordaje laparoscópico. Un 49% realiza algún test preoperatorio para SARS-CoV-2, y el 57% comunican haber tenido casos de confirmación postoperatoria tras alguna intervención, con peor evolución postoperatoria en el 54%. Conclusiones: Esta encuesta revela que las mayorías de los centros están siguiendo las recomendaciones de las sociedades quirúrgicas durante la pandemia por COVID-19. Sin embargo, se observan algunos datos que precisan ser tenido en cuenta en la fase sucesivas de la pandemia.

Two-stage liver resections were described to increase the resectability of liver tumors in patients with insufficient future liver remnant. The ALPPS procedure, described in 2011, has represented a breakthrough in the field of hepato-pancreato-biliary surgery. This technique accelerates the hypertrophy of the future liver remnant and reduces the interval between the two surgeries compared with previous techniques. ALPPS has gained popularity rapidly, with more than 1200 patients included in the world registry. Recommendations about indications, patient selection and surgical standardization have been discussed twice in international expert meetings. Although ALPPS has proven to be superior in terms of resectability (80-100% versus 60-90% of twostage hepatectomy), its rapid implementation has been punished with high morbidity and mortality reaching up to 40% and 9%, respectively, in the published series. The current evidence on the possible benefits and disadvantages is mainly based on observational studies. We present a historical review, describing the different technical modifications that have been carried out since its description, with a rigorous review in terms of morbidity, mortality, and oncological outcomes.

Objetivos: La lesión del nervio laríngeo recurrente es una grave complicación en cirugía tiroidea. El propósito del presente estudio es analizar la utilizad de la neuromonitorización vagal continua intraoperatoria en un hospital terciario.Material y métodos: Estudio observacional, analítico y retrospectivo que recoge pacientes intervenidos de cirugía tiroidea con neuromonitorización en un periodo de 14 meses. La pérdida de señal se define como amplitud final nerviosa < 100 µV, realizándose laringoscopia postquirúrgica ante la sospecha de lesión nerviosa. El análisis estadístico se realizó con el programa SPSS® V25,0, con p < 0,05.Resultados: Se incluyeron 120 pacientes intervenidos, registrándose en el 24,2 % pérdida de señal. Factores de riesgo para lesión fueron bocio intratorácico (OR 5,31; IC 95 % 1,56 – 17,99; p = 0,007), cirugía cervical previa (OR 5,76; IC 95 % 0,64 – 51,97; p = 0,119) y patología maligna (OR 1,44; IC 95 % 0,16 – 12,79; p = 0,743). Fue posible el cambio de estrategia quirúrgica en 7 casos. En el seguimiento posterior se cuantificó parálisis recurrencial transitoria en 27 pacientes y permanente en 4.Discusión: La neuromonitorización parece reducir la incidencia de parálisis laríngea porque aumenta la seguridad en la identificación del nervio recurrente y reduce su manipulación durante la cirugía.Conclusiones: La neuromonitorización intraoperatoria es útil para identificar el nervio laríngeo recurrente y advierte del riesgo potencial de lesión, permitiendo cambiar la estrategia quirúrgica para evitar la parálisis bilateral de cuerdas vocales.

Introduction Enhanced recovery after surgery (ERAS) has been shown to facilitate discharge, decrease length of stay, improve outcomes and reduce costs. We used this concept to design a comprehensive fast-track pathway (OR-to-discharge) before starting our liver transplant activity and then applied this protocol prospectively to every patient undergoing liver transplantation at our institution, monitoring the results periodically. We now report our first six years results. Patients and methods Prospective cohort study of all the liver transplants performed at our institution for the first six years. Balanced general anesthesia, fluid restriction, thromboelastometry, inferior vena cava preservation and temporary portocaval shunt were strategies common to all cases. Standard immunosuppression administered included steroids, tacrolimus (delayed in the setting of renal impairment, with basiliximab induction added) and mycophenolate mofetil. Tacrolimus dosing was adjusted using a Bayesian estimation methodology. Oral intake and ambulation were started early. Results A total of 240 transplants were performed in 236 patients (191♂/45♀) over 74 months, mean age 56.3±9.6 years, raw MELD score 15.5±7.7. Predominant etiologies were alcohol (n = 136) and HCV (n = 82), with hepatocellular carcinoma present in 129 (54.7%). Nine patients received combined liver and kidney transplants. The mean operating time was 315±64 min with cold ischemia times of 279±88 min. Thirty-one patients (13.1%) were transfused in the OR (2.4±1.2 units of PRBC). Extubation was immediate (p=0.015) in the fast-track group. Patient survival was 86.8% at 1 year and 78.6% at five years. Conclusion Fast-Tracking of Liver Transplant patients is feasible and can be applied as the standard of care

Introducción El número de citas se considera un indicador indirecto del mérito de un artículo, revista o investigador, aunque no es un método infalible para determinar la calidad científica. Nuestro objetivo es determinar las características de los artículos más citados sobre páncreas y laparoscopia. Métodos Realizamos una búsqueda de todos los artículos publicados en cualquier revista sobre páncreas y laparoscopia hasta septiembre de 2019 y seleccionamos los 100 artículos más citados. Registramos el número de citas, la revista, el año de publicación, el cuartil, el factor de impacto, la institución, el país, el tipo de artículo de los autores, el tipo de cirugía, el tema y el área. Resultados El top 100 suma 10.970 citas. La revista con más artículos es Surgical Endoscopy y 2007 es el año con el mayor número de artículos en el top 100. El porcentaje de publicaciones de América y Europa es similar. Las series de casos son el tipo de artículo más frecuente, los resultados/morbilidad es el tema más discutido y la pancreatectomía distal es el tipo de cirugía más frecuente. Conclusiones Este estudio bibliométrico sobre páncreas y laparoscopia está condicionado por el factor tiempo, ya que la laparoscopia ha llegado más tarde a la cirugía pancreática, probablemente debido a la morbimortalidad asociada a la cirugía pancreática y a la necesidad de una alta especialización en este campo. La literatura es reciente y escasa. Se necesitan más estudios y de mayor calidad en este campo. Introduction: The number of citations is considered as an indirect indicator of the merit of an article, journal or researcher, although it is not an infallible method to determine scientific quality. Our goal is to determine the characteristics of the articles most cited about pancreas and laparoscopy. Methods: We performed a search of all articles published in any journal about pancreas and laparoscopy until September 2019 and selected the 100 most cited papers. We recorded number of citations, journal, year of publication, quartil, impact factor, institution, country, authors type of paper, type of surgery, topic and area. Results: The top 100 citations account 10, 970 citations in total. The journal with the most articles is Surgical Endoscopy and 2007 is the year with the highest number of articles in the top 100 citations. The percentage of publications from America and Europe are similar. Case series is the most frequently paper, outcomes/morbidity is the most frequently discussed topic, and distal pancreatectomy is the most frequently type of surgery. Conclusions: This bibliometric study on pancreas and laparoscopy is conditioned by the time factor, since laparoscopy has arrived later at pancreatic surgery, probably due to the morbidity and mortality associated with pancreatic surgery and the need for a high specialization in this field. The literature is recent and scarce. More and better-quality studies are needed in this field.

Background: the extent of the COVID-19 pandemic and the resulting response has varied globally. The European and African Hepato-Pancreato-Biliary Association (E-AHPBA), the premier representative body for practicing HPB surgeons in Europe and Africa, conducted this survey to assess the impact of COVID-19 on HPB surgery. Methods: an online survey was disseminated to all E-AHPBA members to assess the effects of the pandemic on unit capacity, management of HPB cancers, use of COVID-19 screening and other aspects of service delivery. Results: overall, 145 (25%) members responded. Most units, particularly in COVID-high countries (>100,000 cases) reported insufficient critical care capacity and reduced HPB operating sessions compared to COVID-low countries. Delayed access to cancer surgery necessitated alternatives including increased neoadjuvant chemotherapy for pancreatic cancer and colorectal liver metastases, and locoregional treatments for hepatocellular carcinoma. Other aspects of service delivery including COVID-19 screening and personal protective equipment varied between units and countries. Conclusion: this study demonstrates that the COVID-19 pandemic has had a profound adverse impact on the delivery of HPB cancer care across the continents of Europe and Africa. The findings illustrate the need for safe resumption of cancer surgery in a “new” normal world with screening of patients and staff for COVID-19., NA

Background Renal cell carcinoma (RCC) can lead to secondary pancreatic tumors even years after nephrectomy was performed. Surgical resection in selected patients shows appropriate survival rates. Methods A systematic review was performed following PRISMA guidelines. This review finished in May 2019 and included patients with resected pancreatic metastasis(es). The main purpose was to evaluate the results of surgical resection of pancreatic tumors secondary to kidney cancer. Results After the screening process of articles, 21 were selected for the systematic review, which included 354 patients, whose disease-free interval (DFI) was 105.11 (0–361.56) months. Of these patients, 34.6% had additional metastases elsewhere at the time of the surgery, and 48.6% were symptomatic. Postoperative morbidity was 40.2%, The 5-year overall survival (OS) rate was 53.9% (26–75). Conclusion Pancreatic surgery for the resection of RCC metastasis(es) is considered safe and shows low morbidity and mortality rates among selected patients in medical institutions where this type of procedure is commonly performed.

Combined hepatic and inferior vena cava (IVC) resection is the only potentially curative treatment for patients with colorectal liver metastases (CRLM) involving the IVC. Most of the existing data come from case reports or small case series. In this paper, a systematic review based on the PICO strategy was performed in accordance with the PRISMA statement. Papers from January 1980 to December 2022 were searched in Embase, PubMed, and the Cochrane Library databases. Articles considered for inclusion had to present data on simultaneous liver and IVC resection for CRLM and report surgical and/or oncological outcomes. From a total of 1175 articles retrieved, 29, including a total of 188 patients, met the inclusion criteria. The mean age was 58.3 ± 10.8 years. The most frequent techniques used were right hepatectomy ± caudate lobe for hepatic resections (37.8%), lateral clamping (44.8%) for vascular control, and primary closure (56.8%) for IVC repair. The thirty-day mortality reached 4.6%. Tumour relapse was reported in 65.8% of the cases. The median overall survival (OS) was 34 months (with a confidence interval of 30–40 months), and the 1-year, 3-year, and 5-year OS were 71.4%, 19.8%, and 7.1%, respectively. In the absence of prospective randomized studies, which are difficult to perform, IVC resection seems to be safe and feasible.

Background The aim of international health cooperation projects is to alleviate the deficiencies in the area of health in low resource settings. Hernia surgery is a procedure that is well suited to these missions, due to its low morbidity, the fact that it can be performed on an outpatient basis, and the improvement in quality of life that it provides. Objective To describe the results of Benefica Chirurgia (BC), a Spanish non-profit humanitarian association in hernia pathology. Methods Five one-week surgical campaigns were carried out in Ecuador between 2015 and 2019, involving anesthetists, general and pediatric surgeons. Surgical and medical equipment was provided and transported by BC. ASA I/II patients underwent surgery. Results Surgery was performed on 240 patients with hernia pathology on 27 days. Sixty-three per cent of patients were male and the mean age was 48.2 years (range: 1–83). Hernia location was inguinal in 113 patients, umbilical in 101, and other in 26. The anesthetic technique used was spinal in 185 patients (77.1%), local plus intravenous sedation in 31 (12.9%), and general in 24 (10%). The surgical technique used was hernioplasty in 191 patients, herniorrhaphy in 31, incisional hernia repair in 15 and herniotomy in three. Surgery was performed on an outpatient basis in 98.4% of cases. Morbidity was 2%. Long-term postoperative evaluation is very complex. Conclusion These campaigns make a significant contribution to health in low resource settings and provide great personal satisfaction for those involved. Standards achieved in the immediate postoperative period were similar to those obtained at the surgeons’ centers in Europe. However, it is difficult to establish the rates of recurrence and chronic pain.

Background: Hepatocellular carcinoma is the most common type of primary liver cancer and is the third cause of cancer related deaths; 80% of the HCC are associated with cirrhotic livers or chronic liver diseases, which constitute the main risk factor. Chronic inflammation, necrosis and regeneration due to these conditions produce genetic mutation and development of tumor cells. Yet, 10% develop in non-cirrhotic healthy livers without precipitating factors. Material and methods: We conducted a retrospective analysis of the characteristics and survival of patients with diagnosis of hepatocellular carcinoma in non-cirrhotic liver and absence of a history of liver cirrhosis or chronic liver disease undergoing surgery in two hepato-pancreato-biliary units between January 2007 and January 2016. Results: Mean age was 65 years and 13 patients were men. Abdominal pain was the most common clinical presentation. Liver panel was normal in 60% of the cases and alpha-fetoprotein was elevated in only 16%. The diagnosis was made by imaging tests in 61% of the cases. Mean tumor size was 110.6 cm. All the patients underwent surgery. Complications were observed in 36.8% of the patients and survival at 5 years was 62.3%. Conclusion: hepatocellular carcinoma is usually diagnosed as a large lesion in imaging tests ordered due to abdominal pain. Surgery provides curative treatment, and large resections can be safely performed, with low perioperative morbidity and mortality and low incidence of postoperative liver failure,since the liver remnant is healthy and liver function is maintained.

Postoperative complications represent a basic quality indicator for measuring outcomes at surgical units. At present, however, they are not systematically measured in all surgical procedures. A more accurate assessment of their impact could help to evaluate the real morbidity associated with different surgical interventions, establish measures for improvement, increase efficiency and identify benchmarking services. The Clavien-Dindo Classification is the most widely used system worldwide for assessing postoperative complications. However, the postoperative period is summarized by the most serious complication without taking into account others of lesser magnitude. Recently, two new scoring systems have emerged, the Comprehensive Complication Index and the Complication Severity Score, which include all postoperative complications and quantify them from 0 (no complications) to 100 (patient’s death), These allow the comparison of results. It is important to train surgical staff to report and classify complications and to record 90-d morbidity rates in all patients. Comparisons with other services must take into account patient comorbidities and the complexity of the particular surgical procedure. To avoid subjectivity and bias, external audits are necessary. In addition, ensuring transparency in the reporting of the results is an urgent obligation.

Introduction The technical, human, scientific and treatment characteristics of the Units that manage complex pathologies have not been studied in depth. Methods Multi-institutional descriptive study (survey) developed jointly by the Hepatobiliary-Pancreatic Division of the Spanish Association of Surgeons and the Spanish Chapter of the IHPBA (International Hepatopancreatobiliary Association) on the characteristics of the Units where pancreatic surgery is performed in Spain. Results 82 surveys were sent. 69 medical centers responded (84%), belonging to 16 autonomous regions of Spain. The total population of these regions was 23 183 262 (50% of the Spanish population). The average number of beds per hospital was 673. The unit that performs pancreatic surgery is a Hepatobiliary-Pancreatic Surgery Unit or HPB and Liver Transplant Surgery Unit in 56 hospitals (77%). The average number of surgeons is 4.5 per Unit. Fifty-five Units (80%) lack specific anesthetists. The number of pancreatectomies performed during 2017 at the hospitals surveyed was 1315 pancreaticoduodenectomies (PD), 566 distal pancreatectomies (DP) and 178 total pancreaticoduodenectomies (TPD). The mean per hospital was 19.1 PD, 8.2 DP and 2.6 TPD. PD was usually performed using a classic approach, with pancreatojejunostomy, single-loop technique, antecolic gastrojejunostomy and using two drain tubes. Only 7 units performed PD laparoscopically and only 13 units did not perform laparoscopic DP. Conclusions This survey provides updated information about the majority of the Units where pancreatic surgery is performed in Spain and could also serve as a starting point for prospective multicenter studies.

Purpose Echinococcosis, also known as hydatidosis, is a zoonosis that is endemic in many countries worldwide. Liver hydatid cysts have a wide variety of clinical manifestations, among which obstructive jaundice is one of the rarer forms. The aims of the study were to analyze the preoperative management of these patients and to record the kind of surgical treatment performed and the short- and long-term postoperative results. Methods A retrospective two-center observational study of patients operated upon for liver hydatidosis with initial symptoms of obstructive jaundice. Preoperative characteristics, surgical data, and postoperative complications, including biliary fistula, were recorded. Results Of 353 patients operated upon for liver hydatidosis, 44 were included in the study. Thirty-five patients (79.6%) were defined as CE2 or CE3 in the World Health Organization (WHO) classification. Preoperative endoscopic retrograde cholangiopancreatography (ERCP) was performed in 25 patients (56.8%) and identified intrabiliary communication in 29. Radical surgery was carried out in 29 of the total sample (65.9%). Severe postoperative complications (Clavien-Dindo grade IIIA or higher) were recorded in 25% of patients. The factors associated with greater postoperative morbidity were age above 65 (HR 8.76 [95% CI 0.78-97.85]), cyst location (HR 4.77 [95% CI 0.93-24.42]), multiple cysts (HR 14.58 [95% CI 1.42-149.96]), and cyst size greater than 5 cm (HR 6.88 [95% CI 0.95-50]). Conclusion The presentation as obstructive jaundice causes greater postoperative morbidity. The main postoperative complication in these cases, despite radical surgery, is biliary fistula. In our series, routine preoperative ERCP did not show any benefit.

Graphical abstract, Introduction The extraordinary impact of COVID-19 pandemic on Spanish hospitals has led to a redistribution of resources for the treatment of these patients, with a decreased capacity of care for other common diseases. The aim of the present study is to analyse how this situation has affected the treatment of cholecystitis and cholelythiasis. Methods It is a descriptive national study after online voluntary distribution of a specific questionnaire with Google Drive™ to members of the Spanish Association of Surgeons (AEC). Results We received 153 answers (one per hospital). Elective cholecystectomies have been cancelled in 96.7% of centres. Conservative treatment for acute cholecystitis has been selected in 90% (previously 18%), and if operated, 95% have been performed laparoscopically. Globally, only 49% perform preoperative diagnostic tests for SARS-CoV-2, and 58.5% recognize there have been cases confirmed postoperatively after other surgeries, with worse surgical outcomes in 54%. Conclusions This survey shows that most of the Spanish centers are following the surgical societies suggestions during the pandemic. However, some data requires to be taken into account for the next phase of the pandemic.

The intrapancreatic accessory spleen is a congenital entity whose differential diagnosis is mainly raised with neuroendocrine tumors of the pancreas. Keeping in mind this unfrequent entity and careful interpretation of the imaging tests, especially magnetic resonance imaging, can give us the key to make a correct definitive diagnosis. Successful diagnosis is important in order to try to avoid diagnostic pancreatectomies that could carry out severe morbidity.

Introduccion: la cirugia radical en hidatidosis hepatica se asocia con menor morbilidad y recurrencia que la conservadora. Material y metodos: realizamos un estudio observacional retrospectivo de pacientes con cirugia de quiste hidatidico hepatico. Se incluyeron 71 pacientes con 90 quistes entre 2007 y 2017. Se realizo cirugia radical en el 69,01 %. Resultados: no hubo diferencias en morbimortalidad, fuga biliar o recurrencia segun cirugia. Los quistes complicados se asociaron con mayor estancia y morbilidad. Conclusiones: la toma de decisiones debe considerar edad/comorbilidad, caracteristicas del quiste y recursos disponibles. La cirugia radical debe ser aplicada siempre que sea factible, con mejores resultados con una adecuada seleccion de pacientes.

Background Multivisceral resection (MVR) is sometimes necessary to achieve disease-free margins in cancer surgery. In certain patients with pancreatic tumors that invade neighboring organs these must be removed to perform an appropriate oncological surgery. In addition, there is an increasing need to perform resections of other organs like liver not directly invaded by the tumor but which require synchronous removal. The results of MVR in pancreatic surgery are controversial. Material and methods A distal pancreatectomy retrospective multicenter observational study using prospectively compiled data carried out at seven HPB Units. The period study was January 2008 to December 2018. We excluded DP with celiac trunk resection. Results 435 DP were performed. In 62 (14.25%) an extra organ was resected (82 organs). Comparison of the preoperative data of MVR and non-MVR patients showed that patients with MVR had lower BMI, higher ASA and larger tumor size. In the MVR group, the approach was mostly laparotomic and spleen preservation was performed only in 8% of the cases, Blood loss and the percentage of intraoperative transfusion were higher in MVR group. Major morbidity rates (Clavien > IIIa) and mortality (0.8vs.4.8%) were higher in the MVR group. Pancreatic fistula rates were practically the same in both groups. Mean hospital stay was twice as long in the MVR group and the readmission rate was higher in the MVR group. Histology study confirmed a much higher rate of malignant tumors in MVR group. Conclusions In order to obtain free margins or treat pathologies in several organs we think that DP + MVR is a feasible technique in selected patients; the results obtained are not as good as those of DP without MVR but are acceptable nonetheless.

Liver transplantation (LT) is one of the most complex surgical procedures. Enhanced recovery after surgery (ERAS) aims to reduce the risk of postoperative complications. When patients achieve all desirable outcomes after a procedure, they are considered to have experienced a textbook outcome (TO).Two cohorts of patients undergoing low (n = 101) or medium risk (n = 15) LT were identified. The remaining patients (n = 65) were grouped separately. The ERAS protocol included pre-, intra-, and post-operative steps. TO was defined as the absence of complications, prolonged length of hospital stays, readmission and mortality during the first 90 days.One third of patients who underwent ERAS after LT experienced a TO. On multivariable analysis, age (OR, 1.05 [95% CI, 1.01-1.09]; P = .02), and having hepatocellular carcinoma (OR, 2.83 [95% CI, 1.37-6.03]; P = .005) were individually associated with a greater probability of achieving a TO. Belonging to the cohorts of medium risk or outside the selection criteria was associated with a lower probability of achieving a TO (OR, 0.46 [96% CI, 0.22-0.93]; P = .03). Patients less likely to experience TO required more hospital resources. Patients who achieved TO were more likely to remain free of chronic kidney disease (achieved TO, 83.8% [82.7-85.6]; failed TO, 67.9% [66.9-70.2]; P .05). Tacrolimus dose and trough levels were similar.A novel finding of our study is that short and medium-term kidney function is better preserved in patients who experience a TO. Better kidney function of patients who achieve TO is not due to lower tacrolimus dosage.

The major symptoms of advanced hepatopancreatic-biliary cancer are biliary obstruction, pain and gastric outlet obstruction (GOO). For obstructive jaundice, surgical treatment should de consider in recurrent stent complications. The role of surgery for pain relief is marginal nowadays. On the last, there is no consensus for treatment of malignant GOO. Endoscopic duodenal stents are associated with shorter length of stay and faster relief to oral intake with more recurrent symptoms. Surgical gastrojejunostomy shows better long-term results and lower re-intervention rates, but there are limited data about laparoscopic approach. We performed a systematic review of the literature, according PRISMA guidelines, to search for articles on laparoscopic gastrojejunostomy for malignant GOO treatment. We also report our personal series, from 2009 to 2017. A review of the literature suggests that there is no standardized surgical technique either standardized outcomes to report. Most of the studies are case series, so level of evidence is low. Decision-making must consider medical condition, nutritional status, quality of life and life expectancy. Evaluation of the patient and multidisciplinary expertise are required to select appropriate approach. Given the limited studies and the difficulty to perform prospective controlled trials, no study can answer all the complexities of malignant GOO and more outcome data is needed.

espanolEl sindrome metabolico es un conjunto de alteraciones constituido por obesidad de distribucion central, disminucion de las concentraciones del colesterol unido a lipoproteinas de alta densidad, elevacion de las concentraciones de trigliceridos, hipertension arterial e hiperglucemia. Este sindrome se ha convertido en una de las epidemias del siglo XXI. Entre sus agentes causales se encuentran la resistencia a la insulina, la leptina y adiponectina, los cambios en la microbiota y la epigenetica. Se estima una incidencia alrededor del 25% en la poblacion europea. La enfermedad hepatica grasa no alcoholica es la manifestacion hepatica del sindrome metabolico. Su prevalencia es paralela a la de la obesidad, aumentando de forma exponencial en las ultimas decadas. Recientemente, diversas publicaciones han relacionado los factores de riesgo metabolicos con la aparicion y el desarrollo de hepatocarcinoma. En este contexto, es primordial determinar si los pacientes con enfermedad hepatica grasa no alcoholica deben de seguir un protocolo de cribado de hepatocarcinoma. Hasta la fecha, la incidencia mundial publicada de hepatocarcinoma en pacientes con enfermedad hepatica grasa no alcoholica sin cirrosis es del 2,7% a los diez anos. Aunque el screening de hepatocarcinoma en pacientes con enfermedad hepatica grasa no alcoholica y cirrosis es obligatorio, la baja incidencia de hepatocarcinoma en pacientes sin cirrosis no justifica la vigilancia sistematica de esta poblacion de pacientes. Los esfuerzos se basan en determinar los subgrupos de pacientes con enfermedad hepatica grasa no alcoholica con mayor riesgo de desarrollar hepatocarcinoma EnglishThe term “metabolic syndrome” refers to a group of alterations comprising central obesity reduced high-density lipoprotein cholesterol concentrations, elevated triglyceride concentrations, arterial hypertension, and hyperglycemia. This syndrome has established itself as one of the epidemics of the 21st century. Among its causative agents are insulin resistance, leptin and adiponectin, changes in microbiota, and epigenetics. Its incidence in the European population is estimated to be around 25%. Non-alcoholic fatty liver disease is the hepatic manifestation of metabolic syndrome; its prevalence parallels that of obesity, and it has increased exponentially in recent decades. Recently, several publications have linked metabolic risk factors with the onset and development of hepatocarcinoma, and so it is essential to determine whether patients with non-alcoholic fatty liver disease should follow a protocol for hepatocarcinoma screening. At present, the worldwide incidence of hepatocarcinoma in patients with non-alcoholic fatty liver disease without cirrhosis is only 2.7%. Screening for hepatocarcinoma in patients with non-alcoholic fatty liver disease and cirrhosis is mandatory, but the low incidence of hepatocarcinoma in patients without cirrhosis does not justify the systematic monitoring of this patient population. Current efforts are based on identifying subgroups of patients with non-alcoholic fatty liver disease and a higher-than-average risk of developing hepatocarcinoma

Perforation in colorectal cancer is an uncommon condition, and neoplastic invasion of the abdominal wall with local infection is even rarer. Our objective is to present the case of an 84-year-old male with right colon cancer that manifested as an inguinal abscess, and also to perform a systematic review of the literature in PubMed, EMBASE, and Web of Science. A total of 59 cases in retrospective studies were found. Median age was 64 years, thirty cases were men and twenty-nine were women (51% and 49%, respectively). The most common location was the right colon with 27 cases (46%), followed by the left colon with 18 cases (31%), 12 cases in the transverse colon (20%), and 2 cases with colonic synchronous neoplasm (3%). Surgery was performed in two or more occasions for 33 cases (60%), and on one occasion for 21 cases (38%); medical treatment alone was administered in one case (2%). The most common histological type was adenocarcinoma (64%), followed by its mucinous variant (22%). There was recurrence in 33% of cases. Mortality at follow-up was 47%. As a limitation of our study, follow-up was heterogeneous, making it impossible to interpret long-term results regarding the influence of treatment on patient survival, also difficulted by the urgent nature of the condition and its exceptional incidence. Further studies are needed with prospective data collection on the management of colorectal cancer in the emergency setting, standardizing follow-up in order to facilitate an adequate analysis of the prognosis of the disease.

Postoperative complications (PC) are a basic health outcome, but no surgery service in the world records and/or audits the PC associated with all the surgical procedures it performs. Most studies that have assessed the cost of PC suffer from poor quality and a lack of transparency and consistency. The payment system in place often rewards the volume of services provided rather than the quality of patients' clinical outcomes. Without a thorough registration of PC, the economic costs involved cannot be determined. An accurate, reliable appraisal would help identify areas for investment in order to reduce the incidence of PC, improve surgical results, and bring down the economic costs. This article describes how to quantify and classify PC using the Clavien-Dindo classification and the comprehensive complication index, discusses the perspectives from which economic evaluations are performed and the minimum postoperative follow-up established, and makes various recommendations. The availability of accurate and impartially audited data on PC will help reduce their incidence and bring down costs. Patients, the health authorities, and society as a whole are sure to benefit.

Objective: Our aim was to describe our antimicrobial stewardship program and the methodology based on the results in a surgical department. Methods: Our study was a quasi-experimental study conducted from January 1, 2009, through September 30, 2017. The site was the General and Digestive Surgery Department in a public primary referral center, the University Hospital of Getafe (Madrid, Spain). We implemented the antimicrobial stewardship program following a prospective audit and feedback model, with a surgeon incorporated into the manaagement group. We studied the deaths and 30-day re-admission rates, length of stay, prevalence of gram-negative bacilli, meropenem resistance, and days of treatment with meropenem. Results: After three years of the program, we recorded a significant decrease in Pseudomonas aeruginosa prevalence, a significant increase in Klebsiella pneumoniae prevalence, a decrease in meropenem resistance, and a reduction in meropenem days of treatment. Conclusions: Antimicrobial stewardship programs have a desirable effect on patients. In our experience, the program team should be led by a staff from the particular department. When human resources are limited, the sustainability, efficiency, and effectiveness of interventions are feasible only with adequate computer support. Finally, but no less important, the necessary feedback between the prescribers and the team must be based on an ad hoc method such as that provided by statistical control charts, a median chart in our study.

Objective: To provide evidence-based recommendations for the management of exocrine pancreatic insufficiency (EPI) after pancreatic surgery. Background: EPI is a common complication after pancreatic surgery but there is certain confusion about its frequency, optimal methods of diagnosis, and when and how to treat these patients. Methods: Eighteen multidisciplinary reviewers performed a systematic review on 10 predefined questions following the GRADE methodology. Six external expert referees reviewed the retrieved information. Members from Spanish Association of Pancreatology were invited to suggest modifications and voted for the quantification of agreement. Results: These guidelines analyze the definition of EPI after pancreatic surgery, (one question), its frequency after specific techniques and underlying disease (four questions), its clinical consequences (one question), diagnosis (one question), when and how to treat postsurgical EPI (two questions) and its impact on the quality of life (one question). Eleven statements answering those 10 questions were provided: one (9.1%) was rated as a strong recommendation according to GRADE, three (27.3%) as moderate and seven (63.6%) as weak. All statements had strong agreement. Conclusions: EPI is a frequent but under-recognized complication of pancreatic surgery. These guidelines provide evidence-based recommendations for the definition, diagnosis, and management of EPI after pancreatic surgery.

espanolObjetivo: el objetivo de este estudio es evaluar los motivos y el momento de reingreso hospitalario despues de colecistectomia comparando los pacientes en base a la realizacion de una colangiopancreatografia retrograda endoscopica (CPRE) previa o no. Metodo: retrospectivamente, se revisaron todos los pacientes sometidos a colecistectomia en el Servicio de Cirugia General y del Aparato Digestivo del Hospital Universitario de Guadalajara entre enero de 2011 y diciembre de 2016. Se incluyeron pacientes sometidos a colecistectomia reingresados en cualquier servicio del hospital en los 90 dias posteriores a la cirugia. Los criterios de exclusion fueron: colecistectomia asociada a otros procedimientos, patologia oncologica activa en el momento de la colecistectomia, ingresos programados previamente por otra patologia no relacionada y presencia de histologia tumoral en la pieza de colecistectomia. Resultados: se estudiaron 1.714 pacientes, de los cuales 80 pacientes fueron readmitidos durante los 90 dias posteriores al alta de la colecistectomia. La tasa de readmision fue del 4,67%. La realizacion de CPRE previa a la cirugia se asocio a un aumento de la morbilidad postoperatoria (40% vs. 21,54%). La realizacion previa de una CPRE disminuyo la aparicion de complicaciones de tipo biliar en los 90 dias posteriores a la colecistectomia. Se observo tambien un aumento del numero de dias hasta que se produce el reingreso en estos pacientes (22 dias con CPRE vs. siete dias sin CPRE). Conclusion: en nuestra serie, los pacientes que precisaron una CPRE previa a la colecistectomia presentaron mayor morbilidad postoperatoria. Sin embargo, los pacientes que no precisaron CPRE presentaron mas complicaciones biliares y tuvieron reingresos mas tempranos. EnglishAim: the aim of this study was to assess the reasons for and the time of hospital readmissions after cholecystectomy, according to whether an endoscopic retrograde cholangiopancreatography (ERCP) was performed. Method: all patients that underwent cholecystectomy at the Service of Digestive Diseases and General Surgery of the Hospital Universitario de Guadalajara between January 2011 and December 2016 were retrospectively reviewed. Patients who underwent cholecystectomy and were readmitted to any hospital service within 90 days of surgery were included. The following cases were excluded: patients that underwent cholecystectomy in combination with other procedures, an active oncological pathology at the time of cholecystectomy, admissions previously scheduled for another unrelated pathology and those with tumor histology in the cholecystectomy specimen. Results: of a total of 1,714 patients, 80 were readmitted within 90 days of discharge after cholecystectomy, which equates to a readmission rate of 4.6%. The performance of an ERCP prior to surgery was associated with an increase in postoperative morbidity (40% vs 21.54%). A prior ERCP reduced the rate of biliary complications during the 90 days after cholecystectomy. Furthermore, there was an increase in the number of days prior to readmission in these cases, with a mean period of 22 days with ERCP vs seven days without ERCP. Conclusion: patients in our series who required an ERCP prior to cholecystectomy had a greater postoperative morbidity. However, those that did not require ERCP had more biliary complications and were readmitted earlier.
