Whipple's cephalic pancreaticoduodenectomy versus pyloric-preserving pancreaticoduodenectomy. Retrospective study.

INTRODUCTION: Controversy exists in the literature as to the best technique for pancreaticoduodenectomy (PD), whether pyloric preservation (PP-CPD) or Whipple's technique (with antrectomy [W-CPD]), the former being associated with a higher frequency of delayed gastric emptying (DGE). METHODS: Retrospective and comparative study between PP-CPD technique (n = 124 patients) and W-CPD technique (n = 126 patients), in patients who were operated for tumors of the pancreatic head and periampullary region between the period 2012 and 2023. RESULTS: Surgical time was longer, although not significant, with the W-CPD technique. Pancreatic and peripancreatic tumor invasion (p = 0.031) and number of lymph nodes resected (p < 0.0001) reached statistical significance in W-CPD, although there was no significant difference between the groups in terms of lymph node tumor invasion. Regarding postoperative morbimortality (medical complications, postoperative pancreatic fistula [POPF], hemorrhage, RVG, re-interventions, in-hospital mortality, Clavien-Dindo complications), ICU and hospital stay, no statistically significant differences were observed between the groups. During follow-up, no significant differences were observed between the groups for morbidity and mortality at 90 days and survival at 1, 3 and 5 years. Binary logistic regression analysis for DGE showed that binary relevant POPF grade B/C was a significant risk factor for DGE. CONCLUSIONS: Postoperative morbidity and mortality and long-term survival were not significantly different with PP-CPD and W-CPD, but POPF grade B/C was a risk factor for DGE grade C.

Post-transplant biliary complications using liver grafts from deceased donors older than 70 years: Retrospective case-control study.

BACKGROUND: The shortage of liver grafts and subsequent waitlist mortality led us to expand the donor pool using liver grafts from older donors. AIM: To determine the incidence, outcomes, and risk factors for biliary complications (BC) in liver transplantation (LT) using liver grafts from donors aged > 70 years. METHODS: Between January 1994 and December 31, 2019, 297 LTs were performed using donors older than 70 years. After excluding 47 LT for several reasons, we divided 250 LTs into two groups, namely post-LT BC (n = 21) and without BC (n = 229). This retrospective case-control study compared both groups. RESULTS: Choledocho-choledochostomy without T-tube was the most frequent technique (76.2% in the BC group vs 92.6% in the non-BC group). Twenty-one patients (8.4%) developed BC (13 anastomotic strictures, 7 biliary leakages, and 1 non-anastomotic biliary stricture). Nine patients underwent percutaneous balloon dilation and nine required a Roux-en-Y hepaticojejunostomy because of dilation failure. The incidence of post-LT complications (graft dysfunction, rejection, renal failure, and non-BC reoperations) was similar in both groups. There were no significant differences in the patient and graft survival between the groups. Moreover, only three deaths were attributed to BC. While female donors were protective factors for BC, donor cardiac arrest was a risk factor. CONCLUSION: The incidence of BC was relatively low on using liver grafts > 70 years. It could be managed in most cases by percutaneous dilation or Roux-en-Y hepaticojejunostomy, without significant differences in the patient or graft survival between the groups.

Duodenopancreatectomía cefálica en pacientes octogenarios con tumores de páncreas / Cephalic duodenopancreatectomy in octogenarium patients with pancreatic tumors

Introducción: Según estudios previos, la duodenopancreatectomía cefálica (DPC) por cáncer de páncreas (CP) se asocia a un incremento de la supervivencia mediana tanto en pacientes octogenarios como en pacientes de menor edad. Métodos: Estudio retrospectivo y comparativo de la DPC realizada en 30 pacientes≥80 años con CP y en 159 pacientes<80 años. Resultados: Los pacientes octogenarios presentaban una tasa significativamente mayor de morbilidad cardiovascular preoperatoria y un comportamiento tumoral más agresivo (mayor anemia, ictericia y CA 19-9 preoperatorios, invasión vascular y neural y menor frecuencia de resección R0 a pesar de utilizar la misma técnica quirúrgica). No hubo diferencias significativas en cuanto a complicaciones postoperatorias. La mortalidad postoperatoria fue similar en ambos grupos (3,3% en octogenarios versus 3,1% en <80 años). Las causas de mortalidad durante el seguimiento fueron fundamentalmente por recidiva tumoral, complicaciones cardiovasculares y COVID-19 (2 octogenarios). La supervivencia actuarial a 1, 3 y 5 años fue significativamente mayor en pacientes <80 años que en octogenarios (el 85,9%, el 61,1% y el 39,2% versus el 72,7%, el 28,9% y el 9,6%, respectivamente; p=0,001). En el estudio multivariable, la presencia de una fístula pancreática y la no utilización de tutor externo del Wirsung influyeron de forma estadísticamente significativa sobre la mortalidad a 90 días post-DPC. Conclusiones: La morbimortalidad post-DPC es similar en octogenarios y <80 años, aunque la supervivencia a largo plazo es menor por la agresividad tumoral y comorbilidad asociada a la edad avanzada.

Introduction: Current literature supports the claim that performing a cephalic pancreaticoduodenectomy (CPD) as treatment for pancreatic cancer (PC) is associated with an increase in median survival, both in octogenarian (≥80 years) patients as well as younger patients. Methods: This is a retrospective and comparative trial, comparing results for CPD performed on 30 patients ≥80 years with PC and 159 patients <80 years. Results: The patients in the octogenarian group showed a significantly higher rate of preoperative cardiovascular morbidity and a more aggressive tumoral behaviour, including more significant preoperative anemia, jaundice and levels of CA 19-9, higher vascular and neural invasion, and a lower rate of R0 resection despite using the same surgical technique. There were no significant differences in terms of postoperative complications. Postoperative mortality was similar in both groups (3.3% in octogenarians vs. 3.1% in patients <80 years). Mortality during follow-up was mainly due to tumour recurrence, cardiovascular complications and COVID-19 in 2elderly patients. Actuarial survival at 1, 3 and 5 years was significantly larger for patients <80 years old, as compared to octogenarians (85.9%, 61.1% and 39.2% versus 72.7%, 28.9% and 9.6%, respectively; P=0.001). The presence of a pancreatic fistula and not using external Wirsung stenting were significantly associated with 90-day postoperative mortality after a CPD. Conclusions: Morbidity and mortality post-CPD is similar in octogenarians and patients younger than 80, although long-term survival is shorter due to more aggressive tumours and comorbidities associated with older age.

“Long-term follow-up of liver transplantation in incidental intrahepatic cholangiocarcinoma and mixed hepatocellular-cholangiocarcinoma” / “Seguimiento a largo plazo del trasplante hepático en el colangiocarcinoma y hepatocolangiocarcinoma mixto incidentales”

Introduction: The standard treatment for intrahepatic cholangiocarcinoma (iCCA) and mixed hepatocellular-cholangiocarcinoma (HCC-CC) is surgical resection, nevertheless, recent studies show adequate survival rates in selected patients with iCCA or HCC-CC undergoing liver transplantation (LT). Methods: A retrospective cohort study was design including all patients undergoing LT at our center between January, 2006 and December, 2019 with incidentally diagnosed iCCA or HCC-CC after pathological examination of the explanted liver (n = 13). Results: There were no iCCA or HCC-CC recurrences during the follow-up, and hence, there were no tumor related deaths. Global and disease-free survival were the same. The 1, 3 and 5-years patient survival were 92.3%, 76.9% and 76.9%, respectively. Survival rates in the “early-stage tumor group” at 1, 3 and 5 years were 100%, 83.3% and 83.3%, respectively, with no significant differences as compared to the “advanced-stage tumors group”. No statistically significant differences in terms of 5-year survival were found when comparing tumor histology (85.7% for iCCA and 66.7% for HCC-CC). Conclusions: These results suggest that LT could be an option in patients with chronic liver disease who develop an iCCA or HCC-CC, even in highly selected advanced tumors, but we must be cautious when analyzing these results because of the small sample size of the series and its retrospective nature.

Introducción: El tratamiento de elección del colangiocarcinoma intrahepático (iCCA) y el hepato-colangiocarcinoma mixto (HCC-CC) es la resección quirúrgica, sin embargo, estudios recientes han demostrado buenos resultados en pacientes seleccionados sometidos a un trasplante hepático (TH). Métodos: Estudio retrospectivo de una cohorte formada por todos los pacientes que recibieron un TH en nuestro centro entre Enero 2006 y Diciembre 2019 con hallazgo incidental de un iCCA o un HCC-CC durante el estudio histopatológico después del trasplante (n = 13). Resultados: Después de una mediana de seguimiento de 65 meses no hubo ninguna recurrencia tumoral, por lo que la supervivencia global y libre de enfermedad fueron iguales. La supervivencia a 1, 3 y 5 años de la muestra fue del 92.3%, 76.9% y 76.9%, respectivamente. La supervivencia de los pacientes con un ‘early stage’ a 1, 3 y 5 años fue del 100%, 83.3% y 83.3%, respectivamente; sin encontrar diferencias estadísticamente significativas al compararla con la de los pacientes con un ‘advanced stage’. Aunque la supervivencia de los pacientes con iCCA fue mayor que la de los pacientes con HCC-CC (85.7% vs. 66.7% a 5 años, respectivamente), las diferencias no fueron estadísticamente significativas. Conclusiones: El TH podría ser una opción de tratamiento en pacientes con enfermedad hepática terminal que desarrollan un iCCA o un HCC-CC, incluso en estadios avanzados seleccionados, pero estos resultados deben ser analizado con precaución dada la naturaleza retrospectiva del estudio y el escaso tamaño muestral.

Capsule endoscopy diagnosis of gastrointestinal melanoma.

Melanoma is a cancer that frequently metastasises to the small bowel, but most cases are asymptomatic and are diagnosed postmortem. Therefore, CT and PET CT cannot detect all lesions and conventional endoscopic study only detects 10-20% of lesions. In this study, we present the case of a 68-year-old patient with a history of cutaneous melanoma and a diagnosis of intestinal melanoma. Thanks to capsule endoscopy, two lesions compatible with cutaneous melanoma metastasis to the small bowel were detected, allowing a much more effective surgical planning. Capsule endoscopy is an innovative technique that improves preoperative diagnosis, as it is able to detect bowel segments that cannot be inspected by conventional endoscopy. It also has a better resolution than conventional CT, improving sensitivity in the detection of lesions.

Expanding donor age in liver transplantation using liver grafts from nonagenarian donors.

INTRODUCTION: Satisfactory outcomes in a series of liver transplantations (LT) with octogenarian liver grafts have been reported, as well as several cases of LT using nonagenarian liver grafts with short follow-up. METHODS: From October 2013 to December 2019, we performed 426 LT. Six LTs used nonagenarian livers (case group) and 49 used octogenarian livers (control group). A comparative analysis was performed between groups. Median donor age was significantly higher in the nonagenarian group than in the octogenarian group (90.6 years versus 83.4 years; (P < .001). There was a significant difference in LT indications (P = .026) between the groups, but not in perioperative recipient variables, morbidity, or mortality. The 1-, 3-, and 5-year patient survival rates were 67.7% in the recipients of nonagenarian livers and 85.7%, 78.0%, and 74.4%, respectively, in the recipients of octogenarian livers (P = .631). The 1-, 3-, and 5-year graft survival rates were 66.7% in the recipients of nonagenarian livers and 81.3%, 73.8%, and 70.3%, respectively, in the recipients of octogenarian livers (P = .745). CONCLUSIONS: The results of LT with nonagenarian liver grafts are not significantly different from those obtained with octogenarian donors, taking into consideration the small sample size and careful selection of donors and adequate donor-recipient matching.

Duodenopancreatectomía cefálica y tutorización externa del conducto de Wirsung. Resultados de una serie de 80 casos consecutivos / Pancreaticoduodenectomy and external Wirsung stenting: our outcomes in 80 cases

Introducción: Existe controversia respecto a la técnica ideal de reconstrucción pancreático-yeyunal posresección duodeno-pancreática. La tutorización externa del Wirsung se ha considerado por muchos autores como una técnica con menor incidencia de fístulas y morbimortalidad. Analizamos nuestra experiencia con esta técnica. Pacientes y métodos: Análisis retrospectivo de la morbimortalidad, de una serie de 80 pacientes consecutivos intervenidos, durante 6,5 años, por tumores pancreáticos cefálicos o periampulares realizando resección y pancreático-yeyunostomía con tutorización externa del Wirsung. Resultados: La edad media de los pacientes fue 68,3 ± 9 años y la tasa de resecabilidad del 78%. La consistencia del páncreas era blanda en 51,2% de pacientes y dura en 48,8%. Se preservó el píloro en 43,8%. El tumor más frecuente fue el adenocarcinoma (68,8%) y se consiguió un R0 en 70%. La fístula bioquímica se presentó en 11,2%, la fístula pancreática grado B en 12,5% y la C en 2,5%, mientras que la tasa de reintervención abdominal fue del 10%. La mediana de estancia hospitalaria fue de 16 días y la mortalidad postoperatoria y a 90 días fue del 2,5%. La tasa de retraso del vaciamiento gástrico fue del 36,3%, diabetes de novo del 12,5% e insuficiencia exocrina del 30%. La supervivencia a uno, tres y cinco años fue 80,2, 53,6 y 19,2%. Conclusiones: Aunque nuestras tasas de morbimortalidad con la tutorización externa del Wirsung son bajas, coincidiendo con series más amplias recientemente publicadas, se precisa un análisis comparativo con otras técnicas reconstructivas, con más casos, para elegir la mejor opción después de una duodenopancreatectomía cefálica.

Introduction: There is controversy regarding the ideal pancreaticojejunostomy technique after pancreaticoduodenectomy. Many authors consider the external Wirsung stenting technique to be associated with a low incidence of fistula, morbidity and mortality. We analyse our experience with this technique. Patients and methods: A retrospective analysis of the morbidity and mortality of a series of 80 consecutive patients who had been treated surgically over a 6.5-year period for pancreatic head or periampullary tumors, performing pancreaticoduodenectomy and pancreaticojejunostomy with external Wirsung duct stenting. Results: Mean patient age was 68.3 ± 9 years, and the resectability rate was 78%. The texture of the pancreas was soft in 51.2% of patients and hard in 48.8%. Pylorus-preserving resection was performed in 43.8%. Adenocarcinoma was the most frequent tumor (68.8%), and R0 was confirmed in 70% of patients. Biochemical fistula was observed in 11.2%, pancreatic fistula grade B in 12.5% and C in 2.5%, whereas the abdominal reoperation rate was 10%. Median postoperative hospital stay was 16 days, and postoperative and 90-day mortality was 2.5%. Delayed gastric emptying was observed in 36.3% of patients, de novo diabetes in 12.5%, and exocrine insufficiency in 3. Patient survival rates after 1, 3 and 5 years were 80.2, 53.6 and 19.2%, respectively. Conclusions: Although our low rates of postoperative complications and mortality using external Wirsung duct stenting coincides with other more numerous recent series, it is necessary to perform a comparative analysis with other techniques, including more cases, to choose the best reconstruction technique after pancreaticoduodenectomy.

Reconstrucción anastomótica y drenaje externo del conducto de Wirsung como tratamiento de la estenosis pancreato-yeyunal posduodenopancreatectomía cefálica / Anastomotic reconstruction and external drainage of Wirsung's duct as treatment for pancreaticojejunal stenosis following pancreaticoduodenectomy

Las estenosis anastomóticas pancreato-digestivas posduodenopancreatectomía cefálica (DPC) son complicaciones raras que suelen presentarse a largo plazo. Presentamos 2 casos de estenosis pancreato-yeyunal que comenzaron con un cuadro clínico de pancreatitis recurrente. El diagnóstico se realizó por clínica de pancreatitis (15 episodios en el primer caso con inicio del primero a los 6 años de la DPC; y 12 episodios en el segundo caso con inicio del primero al año de la DPC), tomografía axial computarizada y resonancia magnética. Ambas pacientes se trataron mediante resección de la anastomosis pancreato-yeyunal, incluyendo un margen de parénquima pancreático de 1 cm en contacto con el asa yeyunal, seguida de una nueva pancreato-yeyunostomía término-lateral biplano, con tutorización externa del conducto de Wirsung. El posoperatorio cursó sin incidencias en ambos casos, y tras un periodo de seguimiento de 3 y 2,5 años, respectivamente, las pacientes permanecen asintomáticas, salvo con insuficiencia endocrina y exocrina evidenciadas antes de la reintervención. La reconstrucción de la anastomosis pancreato-yeyunal con drenaje externo del Wirsung es opción válida para tratar los casos de estenosis pancreato-yeyunal post-DPC

Stenosis of the pancreaticodigestive anastomosis (pancreaticogastrostomy and pancreaticojejunostomy) is a very rare complication that usually develops several years after pancreaticoduodenectomy (PD). Only a few cases have been previously reported. We have reviewed the literature and present 2 more cases of pancreaticojejunostomy stenosis that started with episodes of recurrent acute pancreatitis 6 years and 1 year after PD, respectively. Diagnosis was based on symptoms of pancreatitis (12-15 episodes between 5 and 20 months after PD) and CT and MRI scans. Both patients were treated by resection of the pancreaticojejunostomy stenosis, including a 1-cm slice of pancreatic parenchyma in contact with the jejunum, followed by a new well-vascularized two-layer end-to-side PJ with external drainage of the Wirsung duct. Catheter drainage was exteriorized through a jejunal limb using the Witzel technique. Postsurgical course was uneventful in both cases, and after a follow-up period of 3 and 2.5 years, respectively, the patients remain asymptomatic but with endocrine and exocrine insufficiency. Resection of the PJ and construction of a new PJ with external stent drainage of the Wirsung duct is our preferred surgical option in the rare cases of PJ stenosis after a Whipple procedure

Aplicación de la terapia de vacío en el tratamiento de la dehiscencia completa de inserción mucocutánea del estoma / Vacuum-assited closure (vac) therapy in the treatment of the complete dehiscence of the mucocutaneous junction of the stoma

La aplicación de la terapia de vacío en la dehiscencia completa de la inserción mucocutánea de un estoma es algo novedoso, ya que hasta ahora, en el manejo de las complicaciones del estoma se limitaba su uso a dehiscencias parciales del mismo. Aunque es una complicación poco frecuente, tiene gran relevancia, ya que dificulta la adaptación de los dispositivos de ostomía, enlentece la cicatrización de la cavidad dehiscente, requiere el consumo de gran cantidad de recursos humanos y materiales e impacta directamente en la calidad de vida del paciente. El abordaje de este caso se realizó de manera multidisciplinar (Cirugía, Enfermería y Nutrición) implantando una dieta de absorción alta para reducir el débito del estoma, asociando el uso de la terapia de presión negativa en la cavidad dehiscente y dispositivos de ostomía adecuados para la situación

The use of vaccum-assisted therapy in the complete dehiscence of the mucocutaneous junction of the stoma is a new alternative since, to manage stoma complications, its use has been limited to partial dehiscence of the stoma during the last years. It is an uncommon complication, but it has a great relevance, because it complicates the stoma devices adaptation, it slows the healing of the wound, it requires spending more human and material resources and it has a direct impact over the quality of life of the patient. The approach to every case must be carried out in a multidisciplinary way (Surgery, Nursing and Nutrition) giving to the patient a special diet to reduce the stoma debit, associating the use of vaccum-assisted therapy in the dehiscent wound and employing suitable stoma devices for each situation

La papilomatosis biliar difusa puede recidivar después del trasplante hepático en ausencia de focos de carcinoma infiltrante / Tumor recurrence after liver transplantation for diffuse biliary papillomatosis in the absence of invasive carcinoma

La neoplasia papilar intraductal (NPI) o papilomatosis biliar (PB) es una enfermedad recurrente con un alto riesgo de transformación maligna. Cuando la enfermedad afecta de forma difusa a la vía biliar (VB), el trasplante hepático (TH) es la única alternativa terapeútica disponible. Presentamos el caso de un varón de 43 años que debutó con un cuadro de colangitis aguda, siendo diagnosticado de papilomatosis biliopancreática difusa. El paciente fue sometido a una pancreatectomía total en dos tiempos y finalmente, a un TH, descartándose la presencia de focos de carcinoma infiltrante o de afectación ganglionar tanto en el páncreas inicialmente como en el hígado a posteriori. A los dos años de seguimiento, el paciente desarrolló una recidiva hepática multicéntrica cuya biopsia fue compatible con adenocarcinoma de origen biliar. En 2010, Vibert y cols. describieron que en los casos de PB sin presencia de carcinoma infiltrante o afectación ganglionar, el TH era una opción de tratamiento eficaz. Este caso es el primero que describe recidiva de la enfermedad después del TH en ausencia de focos de carcinoma infiltrante y de afectación ganglionar. Cuando la papilomatosis afecta de forma extensa a la VB, es posible que durante el análisis histopatológico pequeños focos de microinfiltración puedan no ser detectados. No obstante, aunque se trata de una enfermedad recidivante, la patogenia es desconocida, y no sabemos si la papilomatosis podría recidivar sobre el injerto después del TH incluso en ausencia de carcinoma infiltrante

Intraductal papillary neoplasm of the bile duct (IPNB) or biliary papillomatosis (BP) is a premalignant entity with high risk of malignant transformation. When the disease extends widely from the intrahepatic to the extrahepatic biliary tree, liver transplantation (LT) is the only option available. We present the case of a 43-year-old male who was admitted in our hospital with an acute cholangitis. He was diagnosed of diffuse biliary and pancreatic papillomatosis. Firstly, we performed a cephalic pancreaticoduodenectomy, then we completed a total pancreatectomy, and finally, after confirming the absence of foci of carcinoma infiltration or lymph nodes involvement, a LT was performed. Foci of carcinoma infiltration or lymph nodes involvement in the liver were not found. After a two-year follow-up the patient developed liver recurrence and the biopsy showed a biliary adenocarcinoma. In 2010, Vibert et al. published a series of three cases concluding that in the absence of invasive carcinoma and positive lymph nodes, LT can be performed with success. The present case is the first to describe recurrence of the disease after LT in the absence of invasive carcinoma and positive lymph nodes in the literature. When the disease affects widely the entire biliary duct, small micro-invasive foci may not be detected. Nevertheless, although we know that it is a recurrent entity, the pathogenesis is unknown, and we do not know if it is possible that papillomatosis recurs over the new liver
