Valorar si tras la pancreatitis aguda biliar existía una insuficiencia pancreática endocrina y si este posible déficit se relacionaba con la gravedad del episodio.
Pacientes y métodosSesenta y tres pacientes con pancreatitis aguda biliar fueron estudiados prospectiva y consecutivamente, 46 mujeres (73%) y 17 varones (27%); 45 casos eran leves y 18, graves. Todos ellos fueron colecistectomizados, ninguno fue sometido a necrosectomía o pancreatectomía. Durante la fase aguda se valoró la gravedad siguiendo los criterios de Atlanta, la existencia de necrosis y su porcentaje determinado por tomografía computarizada dinámica. Durante el seguimiento se valoró la función pancreática endocrina al mes, a los 6 meses y al año del episodio de la pancreatitis aguda mediante diversos tests de función pancreática.
ResultadosAl mes de la pancreatitis aguda biliar se detectaron alteraciones endocrinas en el 50% de los casos, disminuyendo al sexto mes al 30%, persistiendo al año de la pancreatitis aguda en el 25% de los pacientes; sin embargo, éstas no eran secundarias a la pancreatitis, puesto que el test de arginina presentaba valores dentro del rango de la normalidad. El análisis estadístico realizado a fin de valorar la relación existente entre la gravedad de la pancreatitis aguda y los diversos tests de función pancreática endocrina demostró que no existían diferencias significativas (p > 0,05).
ConclusiónLa función pancreática endocrina retorna a la normalidad después de un episodio de pancreatitis aguda de origen biliar tras haberse eliminado la causa primaria de la enfermedad, no detectándose alteración de la reserva funcional endocrina secundaria a la pancreatitis, y no existiendo relación entre dicha función y la gravedad de la enfermedad.
The aim of this study was to assess endocrine pancreatic function after acute biliary pancreatitis and to determine whether there is a relationship between the severity of the disease and endocrine pancreatic function.
Patients and methodsSixty-three consecutive patients with acute biliary pancreatitis were prospectively studied. Forty-six patients (73%) were women and 17 (27%) were men. The disease was mild in 45 patients and severe in 18. All patients underwent cholecystectomy and none underwent necrosectomy or pancreatectomy. During the acute phase, the severity of the disease was assessed using the Atlanta criteria, occurrence of necrosis, and rate of necrosis determined by dynamic computed tomography. During the follow-up, endocrine pancreatic function was assessed by different pancreatic function tests 1 month, 6 months and 1 year after the episode of acute biliary pancreatitis.
ResultsFifty percent of the patients presented endocrine alterations 1 month after the episode of acute biliary pancreatitis, 30% did so after 6 months and 25% did so after 1 year. However, because the Argine test showed values within the normal range, these alterations were not secondary to the pancreatitis. Statistical analysis performed to determine the relationship between the severity of the disease and the results of the different endocrine pancreatic function tests showed no significant differences (p > 0.05).
ConclusionPancreatic endocrine function returns to normal after an episode of acute biliary pancreatitis once the primary cause of the disease has been eliminated. No alterations in functional endocrine reserve secondary to pancreatitis were found. No relationship between endocrine function and severity of the disease was detected.
