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.

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.

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.
