Is long-term follow-up solely by imaging tests safe in non-operated pancreatic neuroendocrine tumors?

INTRODUCTION: the diagnosis of asymptomatic sporadic nonfunctioning pancreatic neuroendocrine tumors (NF-PNETs) has increased significantly due to the widespread use of high-resolution imaging tests, which is why the most appropriate management at the time of diagnosis is the subject of debate, as is how to follow-up patients. AIMS: the objective of this study was to analyze the frequency of imaging and endoscopic studies performed during long-term follow-up. METHODS: a retrospective review was performed of a database collected between January 2008 and December 2020 of patients with an incidental diagnosis of small NF-PNETs; follow-up was closed in March 2023. The imaging tests performed at the time of diagnosis and long-term follow-up were recorded. Growing less than 1 mm per year has not been considered as a worrisome feature. Follow-up was performed through imaging tests, considering endoscopic cytology for lesions with a faster grow rate. RESULTS: fifty-eight patients were included; the median age was 69 years. The initial mean size of the lesions studied was 12.79 mm (5-27). Follow-up was carried out only with computed tomography (CT) or magnetic resonance imaging (MRI). The initial size did not influence the behavior of the lesion in a statistically significant manner. Twenty-eight tumors (45 %) increased in size, with a growth equal to or less than 4 mm in 24 cases. The mean follow-up time was 82.41 months (12-164). No patient developed metastasis or died from PNET progression. CONCLUSIONS: the follow-up of neuroendocrine tumors of small size can be performed safely with only imaging tests.

Análisis de factores de riesgo de vaciamiento gástrico lento tras la duodenopancreatectomía cefálica / Study of risk factors for delayed gastric emptying after partial pancreatoduodenectomy

Introducción: El vaciamiento gástrico lento (VGL) es una de las complicaciones más frecuentes tras la duodenopancreatectomía cefálica. El objetivo del actual estudio es analizar los factores de riesgo de su aparición. Métodos: Análisis de factores de riesgo de VGL sobre una base de datos prospectiva de 390 pacientes intervenidos entre 2013 y 2021. Se realizó un estudio retrospectivo comparativo entre pacientes con y sin VGL y posteriormente un estudio de factores de riesgo de VGL mediante modelos de regresión logística univariante y multivariante. Resultados: La incidencia de VGL en el global de la serie fue del 28%. Un 63% de los pacientes presentaron alguna complicación y la mortalidad postoperatoria fue del 3,1%. Se evidenció que la edad mediana (73 años vs. 68 años, p<0,001) y la creatinina preoperatorias (75 vs. 68.5, p<0,001) eran superiores en el grupo VGL. El estudio de factores de riesgo evidenció que la edad superior a 60 años (p=0,002) y la fístula pancreática (p<0,001) eran factores de riesgo de VGL. Conclusiones: La presencia de fístula pancreática se confirma como factores de riesgo de VGL tras la duodenopancreatectomía. Además, se demuestra que la edad superior a 60 años es un factor de riesgo de VGL. (AU)

Introduction: Delayed gastric emptying is one of the most frequent complications after pancreatoduodenectomy. Methods: We performed an analysis of risk factors for delayed gastric emptying on a prospective database of 390 patients operated on between 2013 and 2021. A comparative retrospective study was carried out between patients with and without delayed gastric emptying and subsequently a study of risk factors for delayed gastric emptying using univariate and multivariate logistic regression models. Results: The incidence of delayed gastric emptying in the overall series was 28%. The morbidity of the group was 63% and postoperative mortality was 3.1%. Focusing in delayed gastric emptying, it was shown that the median age (73 years vs. 68 years, p<0.001) and preoperative creatinine (75 vs. 65.5, p<0.001) were higher in the group with this complication. The study of risk factors showed that age over 60 years (p=0.002) and pancreatic fistula (p<0.001) were risk factors for delayed gastric emptying. Conclusions: The presence of pancreatic fistula is confirmed as risk factor for slow gastric emptying after pancreaticoduodenectomy. In addition, age over 60 years is shown to be a risk factor for slow gastric emptying. (AU)

Defining Surgical Difficulty of Liver Transplantation.

OBJECTIVE: To define technically Diff-LT. SUMMARY OF BACKGROUND DATA: Currently, there is no acknowledged definition of Diff-LT. METHODS: This retrospective study included all first consecutive liver-only transplantations performed in 2 centers from 2011 to 2015. Diff-LT was defined as the combination of the number of blood units transfused, cold ischemia time, and duration of operation, all at or above the median value of the entire population. The correlation of Diff-LT with short- (including the comprehensive complication index) and long-term outcomes was assessed. Outcomes were also compared to the 90-day benchmark cutoffs of LT. Predictors of Diff-LT were identified by multivariable analysis, first using only recipient data and then using all recipient, donor, graft, and surgical data. RESULTS: The study population included 467 patients. The incidence of Diff- LT was 18.8%. Diff-LT was associated with short-term outcomes, including the comprehensive complication index and mortality, but not with patient or graft long-term survival. Previous abdominal surgery, intensive care unitbound at the time of LT, split graft use, nonstandard arterial reconstruction, and porto-systemic shunt ligation were independent predictors of Diff-LT. The proportion of variables below the corresponding LT 90-day benchmark cutoffs was 8/13 (61.5%) for non-Diff-LT, and 4/13 (30.8%) for Diff-LT. CONCLUSIONS: Diff-LT, as defined, occurred frequently. Adjusting modifiable variables might decrease the risk of Diff-LT and improve the postoperative course. This definition of Diff-LT might be useful for patient information, comparison between centers and surgeons, and as a metric in future trials.

Surgical options for the treatment of neuroendocrine neoplasms of the ampulla of Vater: a reference centre experience.

INTRODUCTION: The main objective of this study was to analyse the results of the surgical treatment of ampullary neuroendocrine tumours (NET) based on transduodenal ampullectomy and pancreatoduodenectomy, in a reference centre in hepatobiliopancreatic pathology. METHOD: Retrospective, observational study, including all patients operated on for pancreatic and/or duodenal NET in a reference unit of hepatobiliopancreatic pathology and prospectively registered between January 1st, 1993 and September 30th, 2021. For those parameters not present, retrospective research was performed. Demographic, clinical, analytical and pathological data were analysed. A descriptive study was carried out. Overall and disease-free survival was calculated using Kaplan-Meier curves and the Log-Rank test. RESULTS: Of 181 patients operated on for pancreatic and/or duodenal NET, only 9 were located in the ampulla of Vater, which represents 4.9% of all pancreatic and/or duodenal NET. Pancreatoduodenectomy (PD) was performed in 6 patients, while 3 patients underwent transduodenal ampullectomy (TDA). Longer surgical time and more postoperative complications were observed in the PD group. There were no differences in hospital stay. Overall and disease-free survival at 5 years in the PD group compared to ATD was 83.3% vs. 100% and 50% vs. 100%, respectively. CONCLUSIONS: Ampullary NET without locoregional involvement or risk factors, can be treated by conservative surgeries such as transduodenal ampullectomy.

Opciones en el tratamiento quirúrgico de la neoplasia neuroendocrina de la ampolla de Váter: experiencia en un centro de referencia / Surgical options for the treatment of neuroendocrine neoplasms of the ampulla of Vater: a reference centre experience

Introducción: El objetivo del estudio fue analizar los resultados del tratamiento quirúrgico de las neoplasias neuroendocrinas (NNE) ampulares mediante Ampulectomía transduodenal (ATD) y duodenopancreatectomía cefálica (DPC), en un centro de referencia en patología hepatobiliopancreática. Método: Estudio retrospectivo, observacional, incluyendo los pacientes intervenidos de NNE de páncreas y/o duodenales en una unidad de referencia en patología hepatobilipancreática y registrados prospectivamente entre el 1 de enero de 1993 y el 30 de septiembre de 2021. Para aquellos parámetros no presentes, se realizó una búsqueda retrospectiva. Se analizaron datos demográficos, clínicos, analíticos y anatomopatológicos. Se realizó un análisis descriptivo. La supervivencia global y libre de enfermedad se calculó mediante curvas de Kaplan-Meier y el test de log-rank. Resultados: De 181 pacientes intervenidos de NNE de páncreas y/o duodenales, solo nueve se localizaban en la ampolla de Váter, lo que representa 4,9% de todos los NNE pancreáticos y/o duodenales. Se realizó DPC en seis pacientes, mientras que a tres se les practicó ATD. Se observó mayor tiempo quirúrgico y más complicaciones en el grupo DPC. No hubo diferencias en la estancia hospitalaria. La supervivencia global y libre de enfermedad a cinco años del grupo DPC respecto a la ATD fue de 83,3 vs. 100% y del 50 vs. 100%, respectivamente. Conclusiones: Las NNE ampulares sin afectación locorregional ni factores de riesgo, pueden ser tratadas mediante cirugías preservadoras como la ATD. (AU)

Novel Composite Endpoint for Assessing Outcomes in Liver Transplantation: Arterial and Biliary Complication-Free Survival.

Transplant and patient survival are the validated endpoints to assess the success of liver transplantation (LT). This study evaluates arterial and biliary complication-free survival (ABCFS) as a new metric. ABC, considered as an event, was an arterial or biliary complication of Dindo-Clavien grade ≥III complication dated at the interventional, endoscopic, or surgical treatment required to correct it. ABCFS was defined as the time from the date of LT to the dates of first ABC, death, relisting, or last follow-up (transplant survival is time from LT to repeat LT or death). Following primary whole LT (n = 532), 106 ABCs occurred and 99 (93%) occurred during the first year after LT. An ABC occurring during the first year after LT (overall rate 19%) was an independent factor associated with transplant survival (hazard ratio [HR], 3.17; P < 0.001) and patient survival (HR, 2.7; P = 0.002) in univariate and multivariate analyses. This result was confirmed after extension of the cohort to split-liver graft, donation after circulatory death, or re-LT (n = 658). Data from 2 external cohorts of primary whole LTs (n = 249 and 229, respectively) confirmed that the first-year ABC was an independent prognostic factor for transplant survival but not for patient survival. ABCFS was correlated with transplant and patient survival (ρ = 0.85 [95% CI, 0.78-0.90] and 0.81 [95% CI, 0.71-0.88], respectively). Preoperative factors known to influence 5-year transplant survival influenced ABCFS after 1 year of follow-up. The 1-year ABCFS was indicative of 5-year transplant survival. ABCFS is a reproducible metric to evaluate the results of LT after 1 year of follow-up and could serve as a new endpoint in clinical trials.

Renoportal Anastomosis During Liver Transplantation in Patients With Portal Vein Thrombosis: First Long-term Results From a Multicenter Study.

OBJECTIVE: To evaluate the short- and long-term outcomes of RPA in a large multicentric series. SUMMARY BACKGROUND: The current knowledge on RPA for portal reconstruction during LT in patients with diffuse PVT and a large splenorenal shunt is poor and limited to case reports and small case series. METHODS: All consecutive LTs with RPA performed in 5 centers between 1998 and 2020 were included. RPA was physiological provided it drained the splanchnic venous return through a large splenorenal shunt (≥ 1 cm diameter). Complications of PHT, long-term RPA patency, and patient and graft survival were assessed. RPA success was achieved provided the 3 following criteria were all fulfilled: patients were alive with patent RPA and without clinical PHT. RESULTS: RPA was attempted and feasible in 57 consecutive patients and was physiological in 51 patients (89.5%). Ninety-day mortality occurred in 5 (8.5%) patients, and PHT-related complications occurred in 42.9% of patients. With a median follow-up of 63 months, the 1-, 3- and 5-year patient and graft survival rates were 87%, 83%, and 76% and 82%, 80%, and 73%, respectively. The primary and primary-assisted patency rates at 5 years were 84.5% and 94.3%, respectively. Success was achieved in 90% (27/30) of patients with a follow-up ≥5 years. CONCLUSIONS: Despite a high rate of PHT-related complications, excellent long-term patient and graft survival could be achieved. RPA could be considered successful in the vast majority of patients. The expanded use of RPA is warranted.

Colangiocarcinoma intrahepático: factores pronósticos de recidiva y supervivencia en una serie de 67 pacientes tratados quirúrgicamente en un solo centro / Intrahepatic cholangiocarcinoma: Prognostic factors for recurrence and survival in a series of 67 patients treated surgically at a single center

Introducción: El colangiocarcinoma intrahepático es una neoplasia primaria hepática de mal pronóstico, cuyo único tratamiento curativo es la cirugía. El objetivo de este trabajo ha sido determinar los factores pronósticos de supervivencia del colangiocarcinoma intrahepático tratado quirúrgicamente con intención curativa. Métodos: Se ha recogido una serie de 67 pacientes intervenidos quirúrgicamente de esta neoplasia en el Hospital Universitario de Bellvitge entre 1996 y 2017. Se han analizado los datos epidemiológicos, clínicos, quirúrgicos, anatomopatológicos, de morbilidad, de mortalidad y de supervivencia. Resultados: La morbilidad postoperatoria ha sido del 47,76% y la mortalidad postoperatoria de 1,5%. La linfadenectomía se ha asociado a mayor morbilidad. La supervivencia global ha sido de 91%; 49,2% y 39,8% a los 12, 36 y 60 meses, respectivamente, y la supervivencia libre de enfermedad de 67,2%; 32,8% y 22,4%. La morbilidad postoperatoria en forma de reintervención quirúrgica, la invasión vascular y la quimioterapia adyuvante han demostrado ser factores de mal pronóstico. La invasión vascular en el estudio anatomopatológico fue el factor de riesgo de mayor importancia en la supervivencia. Conclusiones: Este estudio recoge la experiencia de nuestro centro en el tratamiento quirúrgico del colangiocarcinoma intrahepático durante un periodo de 21 años. La linfadenectomía se ha asociado a mayor morbilidad y la afectación vascular en el estudio anatomopatológico ha sido el factor de riesgo más importante en cuanto a la supervivencia. (AU)

Introduction: Intrahepatic cholangiocarcinoma is a primary liver neoplasm whose only curative treatment is surgery. The objective of this study was to determine the prognostic factors for survival of intrahepatic cholangiocarcinoma treated surgically with curative intent. Methods: Sixty-seven patients who had been treated surgically for this neoplasm were collected at Bellvitge University Hospital between 1996 and 2017. Epidemiological, clinical, surgical, anatomopathological, morbidity, mortality and survival data have been analysed. Results: Postoperative morbidity was 47.76%, and postoperative mortality was 1.5%. Lymphadenectomy was associated with increased morbidity. Overall survival was 91%, 49.2% and 39.8% after 12, 36 and 60 months, respectively, and disease-free survival was 67.2%, 32.8% and 22.4%. Postoperative morbidity (reoperation, vascular invasion, adjuvant chemotherapy) were shown to be factors for a poor prognosis. Vascular invasion in the pathological study was the most important risk factor in the survival analysis. Conclusions: This study reflects our centre's experience in the surgical treatment of intrahepatic cholangiocarcinoma over a period of 21 years. Lymphadenectomy was associated with increased morbidity, and vascular invasion in the pathological study was the most important risk factor in the survival analysis. (AU)

Textbook Outcome Following Liver Transplantation.

BACKGROUND: Textbook outcome (TBO) is a patient-oriented composite criterion achieved when all desired main health outcomes are realized. The aim was to assess the incidence and the independent factors associated with TBO following LT. METHODS: This bicentric study included all patients who underwent their first elective liver-only LT between 2011 and 2015. TBO occurred when all the following criteria were fulfilled: no mortality within 90 days, no major complications within 90 days, no reintervention within 90 days (liver graft biopsy, radiological, endoscopic or surgical interventions, or retransplantation), no prolonged intensive care unit stay, and no prolonged hospital stay. Univariable and multivariable analyses were performed to identify factors associated with TBO and to assess whether TBO is an independent factor associated with patient and graft survival. RESULTS: The study population included 530 patients. TBO occurred in 176/530 (33%) patients. Independent factors associated with TBO included the balance of risk score, the use of an intraoperative temporary portacaval shunt, and duration of the operation. TBO was identified as an independent factor associated with graft survival but not patient survival. CONCLUSIONS: TBO might be implemented in the patient-doctor decision-making regarding whether to proceed with LT and in the reporting of patient-level hospital performance related to LT.

Symptomatic Val122del mutated hereditary transthyretin amyloidosis: Need for early diagnosis and prioritization for heart and liver transplantation.

BACKGROUND: Hereditary transthyretin (ATTRv) amyloidosis is an autosomal dominant disease linked to transthyretin gene mutations which cause instability of the transthyretin tetramer. After dissociation and misfolding they reassemble as insoluble fibrils (i.e. amyloid). Apart from the common Val30Met mutation there is a very heterogeneous group of non-Val30Met mutations. In some cases, the clinical picture is dominated by a rapidly evolving restrictive and hypertrophic cardiomyopathy. METHODS: A case series of four liver recipients with the highly clinically relevant, rare and particularly aggressive Val122del mutation is presented. Medical and surgical therapeutic options, waiting list policy for ATTRv-amyloidosis, including the need for heart transplantation, and status of heart-liver transplantation are discussed. RESULTS: Three patients needed a staged (1 patient) or simultaneous (2 patients) heart-liver transplant due to rapidly progressing cardiac failure and/or neurologic disability. Domino liver transplantation was impossible in two due to fibrotic hepatic transformation caused by cardiomyopathy. After a follow-up ranging from 3.5 to 9.5 years, cardiac (allograft) function was maintained in all patients, but neuropathy progressed in three patients, one of whom died after 80 months. CONCLUSIONS: This is the first report in (liver) transplant literature about the rare Val122del ATTRv mutation. Due to its aggressiveness, symptomatic patients should be prioritized on the liver and, in cases with cardiomyopathy, heart waiting lists in order to avoid the irreversible neurological and cardiac damage that leads to a rapid lethal outcome.

Sinusoidal obstruction syndrome as a manifestation of acute antibody-mediated rejection after liver transplantation.

Antibody-mediated rejection (AMR) after liver transplantation is uncommon but, when present, manifests as graft dysfunction. We report the case of a 54-year-old woman who developed portal hypertension with pleural effusion and ascites secondary to sinusoidal obstruction syndrome (SOS) due to acute AMR following an ABO-matched liver transplantation for autoimmune cirrhosis and hepatocellular carcinoma. Initial immunosuppression comprised basiliximab, decreasing prednisone, tacrolimus, and mycophenolate mofetil. After 1 month, she presented with the massive pleural effusion, slight ascites, and normal liver tests. After excluding common causes of pleural effusion, we performed a liver biopsy that showed atypical rejection with the involvement of large centrilobular veins partially occluded by marked endotheliitis and lax fibrosis suggestive of SOS. Direct immunofluorescence study of C4d showed diffuse endothelial sinusoidal staining, and de novo donor-specific anti-human leukocyte antigen antibodies were detected in his blood. Thus, we diagnosed AMR focused on centrilobular veins and initiated treatment with defibrotide, steroid pulses, and diuretics. However, this was ineffective, and the pleural effusion only resolved when plasmapheresis and intravenous immunoglobulin were started. This case shows that AMR can cause SOS with portal hypertension and present with a pleural effusion, and as such, it should be suspected after excluding other more common causes of effusion.

¿Está justificado el retrasplante hepático en la era actual? / Is Liver Retransplantation Justified in the Current Era?

Introducción: El retrasplante hepático (ReTH) es una indicación de TH controvertida. Nuestro objetivo fue determinar la tasa de ReTH y las indicaciones, morbilidad, mortalidad posoperatoria y supervivencia actuarial del paciente retrasplantado en nuestra serie. Métodos: Estudio retrospectivo de una serie prospectiva de 1.645 pacientes trasplantados entre 1984 y 2018. Se analizan los resultados según el tipo de ReTH (precoz vs. tardío), periodo de estudio e indicaciones. Resultados: Hemos realizado 150 ReTH en 140 pacientes. La tasa de ReTH fue de 9%. El 30% (45) de los ReTH fueron precoces, siendo tardíos el otro 70% (105). Las causas más frecuentes fueron: colangitis isquémica (27%), trombosis de la arteria hepática (19%), fallo primario del injerto (15%) y recidiva de la cirrosis por virus de la hepatitis C (VHC) (15%). La duración de la cirugía (395 vs. 270 min; p = 0,001), tiempo de isquemia (435 vs. 390 min; p = 0,005) y necesidad transfusional (8 vs. 5 CH; p = 0,034) fue mayor en los casos de ReTH tardío, mientras que la mortalidad posoperatoria (10 vs. 20%; p = 0,01) fue mejor en los casos de ReTH tardío. La supervivencia actuarial a uno y cinco años fue de 71% y 58%, respectivamente, con una mejoría significativa en la última década (80% y 64%). Por otra parte, la supervivencia en los casos de ReTH por colangitis isquémica es superior que otras indicaciones (78 vs. 51%; p = 0,02). Conclusiones: El retrasplante es complejo y está asociado a una elevada morbimortalidad. Sin embargo, los resultados han mejorado en los últimos años por lo que su indicación está justificada. (AU)

Introduction: Liver retransplantation (LRT) is a controversial indication. Our aim was to evaluate the rate of LRT at our institution, and to analyze its indications and short- and long-term results. Methods: We conducted a retrospective study of a prospectively collected database, including 1645 LT from 1984 to 2018. Results have been analyzed depending on type of LRT (early vs late), study period and indications. Results: We performed 150 LRT in 140 patients. The LRT rate was 9%. Of these, 45 LRT were early (30%), and the other 70% were late LRT. The main indications were: ischemic cholangitis (27%), arterial thrombosis (19%), primary non-function (15%), and HCV recurrence (15%). Mean surgery duration (395 vs. 270 min; P = .001), cold ischemia time (435 vs. 390 min; P = .005) and transfused units required (8 vs. 5 RBC; P = .034) were higher in cases of late LRT. Postoperative mortality (10 vs. 20%; P = .01) was better in cases of late LRT. One- and 5-year actuarial survival rates were 71% and 58%, respectively, which were significantly better during the last decade (80% and 64%). Five-year actuarial survival for ischemic cholangitis is better than other indications, such as recurrence of HCV (78 vs. 51%; P = .02). Conclusions: Liver retransplantation is complex and associated with high morbidity and mortality. However, indications and long-term results have improved during recent years. Therefore, LRT is justified. (AU)

Resultados a largo plazo sobre la resección de la cabeza pancreática por pancreatitis crónica: ¿duodenopancreatectomía cefálica o pancreatectomía cefálica con preservación duodenal? / Long-term results of resection of the head of the pancreas due to chronic pancreatitis: Pancreaticoduodenectomy or duodenum-preserving cephalic pancreatectomy?

INTRODUCCIÓN: El dolor crónico en la pancreatitis crónica es de difícil manejo. El objetivo de nuestro trabajo es la valoración del control del dolor refractario al tratamiento médico en pacientes afectos de masa inflamatoria en la cabeza pancreática, así como comparar dos técnicas quirúrgicas realizadas. MÉTODOS: Estudio retrospectivo sobre pacientes intervenidos entre 1989 y 2011 refractarios al tratamiento médico con predominio inflamatorio en la cabeza pancreática. Se realizó un estudio comparativo a corto y a largo plazo entre los pacientes intervenidos mediante duodenopancreatectomía cefálica (DPC) y/o pancreatectomía cefálica con preservación duodenal (PCPD). RESULTADOS: Se realizaron 22 DPC y 12 PCPD. En el 44% de los casos se presentaron complicaciones posquirúrgicas, siendo las más frecuentes el vaciamiento gástrico retardado (14,7%) y la fístula pancreática (11,7%). No se evidenciaron diferencias estadísticamente significativas según la técnica quirúrgica. Se consiguió el control del dolor de forma satisfactoria en el 85% de los pacientes, hubo un 43% de diabetes mellitus de novo, y la reincorporación a la actividad laboral fue del 88%. Catorce pacientes fallecieron durante el seguimiento; de ellos, 7 a causa de neoplasias, algunas de ellas relacionadas con el consumo de tabaco y alcohol. La supervivencia global a 5 y 10 años fue del 88 y del 75%, respectivamente. CONCLUSIÓN: La resección cefálica en pacientes con dolor intratable en la pancreatitis crónica es una terapéutica eficaz, con buenos resultados a largo plazo en términos de control del dolor y sin diferencias significativas entre ambas técnicas quirúrgicas. Los pacientes con pancreatitis crónica presentan una elevada mortalidad asociada a neoplasias de novo

INTRODUCTION: Chronic pain in chronic pancreatitis is difficult to manage. The objective of our study is to assess the control of pain that is refractory to medical treatment in patients with an inflammatory mass in the head of the pancreas, as well as to compare the two surgical techniques. METHODS: A retrospective study included patients treated surgically between 1989 and 2011 who had been refractory to medical treatment with inflammation of the head of the pancreas. An analysis of the short and long-term results was done to compare patients who had undergone pancreaticoduodenectomy (PD) and/or resection of the head of the pancreas with duodenal preservation (RHPDP). RESULTS: 22 PD and 12 RHPDP were performed. Postoperative complications were observed in 14% of patients, the most frequent being delayed gastric emptying (14.7%) and pancreatic fistula (11.7%). No statistically significant differences were found in terms of surgical technique. Pain control was satisfactory in 85% of patients, 43% presented de novo diabetes mellitus, and 88% returned to their work activities. Fourteen patients died during follow-up, 7 due to malignancies, and some were related to tobacco use and alcohol consumption. The overall 5 and 10 year survival rates were 88% and 75% respectively. CONCLUSIÓN: Cephalic resection in patients with intractable pain in chronic pancreatitis is an effective therapy that provides good long-term results in terms of pain control, with no significant differences between the two surgical techniques. Patients with chronic pancreatitis have a high mortality rate associated with de novo malignancies

Prognostic value and risk stratification of residual disease in patients with incidental gallbladder cancer.

BACKGROUND AND AIM: Given their poor prognosis, patients with residual disease (RD) in the re-resection specimen of an incidental gallbladder carcinoma (IGBC) could benefit from a better selection for surgical treatment. The Gallbladder Cancer Risk Score (GBRS) has been proposed to preoperatively identify RD risk more precisely than T-stage alone. The aim of this study was to assess the prognostic value of RD and to validate the GBRS in a retrospective series of patients. MATERIAL AND METHODS: A prospectively collected database including 59 patients with IGBC diagnosed from December 1996 to November 2015 was retrospectively analyzed. Three locations of RD were established: local, regional, and distant. The effect of RD on overall survival (OS) was analyzed with the Kaplan-Meier method. To identify variables associated with the presence of RD, characteristics of patients with and without RD were compared using Fisher's exact test. The relative risk of RD associated with clinical and pathologic factors was studied with a univariate logistic regression analysis. RESULTS: RD was found in 30 patients (50.8%). The presence of RD in any location was associated with worse OS (29% vs. 74.2%, p = 0.0001), even after an R0 resection (37.7% vs 74.2%, p = 0.003). There was no significant difference in survival between patients without RD and with local RD (74.2% vs 64.3%, p = 0.266), nor between patients with regional RD and distant RD (16.1% vs 20%, p = 0.411). After selecting patients in which R0 resection was achieved (n = 44), 5-year survival rate for patients without RD, local RD, and regional RD was, respectively, 74.2%, 75%, and 13.9% (p = 0.0001). The GBRS could be calculated in 25 cases (42.3%), and its usefulness to predict the presence of regional or distant RD (RDRD) was confirmed (80% in high-risk patients and 30% in intermediate risk p = 0.041). CONCLUSION: RDRD, but not local RD, represents a negative prognostic factor of OS. The GBRS was useful to preoperatively identify patients with high risk of RDRD. An R0 resection did not improve OS of patients with regional RD.

Long-term results of resection of the head of the pancreas due to chronic pancreatitis: Pancreaticoduodenectomy or duodenum-preserving cephalic pancreatectomy? / Resultados a largo plazo sobre la resección de la cabeza pancreática por pancreatitis crónica: ¿duodenopancreatectomía cefálica o pancreatectomía cefálica con preservación duodenal?

INTRODUCTION: Chronic pain in chronic pancreatitis is difficult to manage. The objective of our study is to assess the control of pain that is refractory to medical treatment in patients with an inflammatory mass in the head of the pancreas, as well as to compare the two surgical techniques. METHODS: A retrospective study included patients treated surgically between 1989 and 2011 who had been refractory to medical treatment with inflammation of the head of the pancreas. An analysis of the short and long-term results was done to compare patients who had undergone pancreaticoduodenectomy (PD) and/or resection of the head of the pancreas with duodenal preservation (RHPDP). RESULTS: 22 PD and 12 RHPDP were performed. Postoperative complications were observed in 14% of patients, the most frequent being delayed gastric emptying (14.7%) and pancreatic fistula (11.7%). No statistically significant differences were found in terms of surgical technique. Pain control was satisfactory in 85% of patients, 43% presented de novo diabetes mellitus, and 88% returned to their work activities. Fourteen patients died during follow-up, 7 due to malignancies, and some were related to tobacco use and alcohol consumption. The overall 5 and 10 year survival rates were 88% and 75% respectively. CONCLUSION: Cephalic resection in patients with intractable pain in chronic pancreatitis is an effective therapy that provides good long-term results in terms of pain control, with no significant differences between the two surgical techniques. Patients with chronic pancreatitis have a high mortality rate associated with de novo malignancies.

Endoscopic biliary drainage in unresectable biliary obstruction: the role of endoscopic ultrasound-guidance in a cohort study

Background and study aims: the use of endoscopic ultrasound-guided biliary drainage (EUS-BD) has increased in cases of failed endoscopic retrograde cholangiopancreatography (ERCP) and there are some concerns. The main aim of the study was to determine the role of EUS-BD in a palliative case cohort. The secondary aim was to compare the efficacy, safety and survival of EUS-BD and ERCP procedures. Patients and methods: this was an observational study at a single tertiary institution, with a consecutive inclusion from January 2015 to December 2016. The inclusion criteria were unresectable tumors of the biliopancreatic region with an indication of BD. Statistical comparison analysis was performed between the ERCP and EUS-BD groups. The incidence between groups was compared using the Chi-square and Fisher exact tests. The log rank test was used to compare the risk of death. Results: fifty-two cases with an indication of palliative BD were included in the study. Transpapillary drainage via ERCP was possible in 44 procedures and EUS-BD was required in eight cases; 15.4% of the cohort and seven using lumen apposing metal stent (LAMS). The technical and clinical success of global endoscopic BD was 100% and 88.5% (ERCP: 84.6% and 78.9%; EUS-BD: 100% and 62.5%, respectively). Pancreatitis was the most frequent adverse event (AE) in the ERCP group (9.62%) and bleeding in the EUS-BD (25%). There were fatal AEs in ERCP (1.9%) and EUS-BD (25%) cases. Patient survival was higher with ERCP transpapillary stents compared to EUS-guided stents, which was statistically significant (p = 0.007). Conclusions: the requirement of EUS-BD in palliative biliopancreatic pathology is not marginal. EUS-BD is associated with a lower survival rate and a higher rate of fatal AE, which argues against its use as a first choice procedure
