ABSTRACT
OBJECTIVES: Exocrine pancreatic insufficiency is a frequent and clinically relevant complication of pancreatic cancer probably secondary to pancreatic duct obstruction. We aimed at evaluating the impact of endoscopic pancreatic drainage on pancreatic function in patients with unresectable pancreatic cancer. METHODS: A double-blind, prospective, randomized, single-center, interventional study was designed. Patients undergoing endoscopic retrograde cholangiopancreatography for jaundice secondary to unresectable pancreatic cancer were randomized to biliary drainage (group A) or biliopancreatic drainage (group B). Pancreatic function was evaluated by 13C-mixed triglyceride breath test before and 2 weeks after endoscopic retrograde cholangiopancreatography. Breath test result is expressed as 13C-cumulative recovery rate. Abdominal symptoms and nutritional markers were evaluated as secondary outcomes. RESULTS: Twenty patients were included. Sixteen patients had exocrine pancreatic insufficiency, and 13 completed the study (7 in group A and 6 in group B). The median absolute improvement of 13C-cumulative recovery rate was of 23.75% (interquartile range, 9.62-31.74) after biliopancreatic drainage compared with -1.92% (interquartile range, -4.17 to 13.92) after biliary drainage (P = 0.015). Nutritional markers improved after biliopancreatic drainage, but not after biliary drainage. CONCLUSIONS: Biliopancreatic and not biliary endoscopic drainage is associated with a significant improvement of exocrine pancreatic function in patients with unresectable pancreatic cancer.

INTRODUCCIÓN: El esófago de Barrett (EB) es una lesión esofágica ocasionada mayoritariamente por reflujo gastroesofágico ácido. El control del reflujo ácido es uno de los principales objetivos del tratamiento de esta patología. OBJETIVO: Evaluar en nuestra área de salud el grado de control del reflujo ácido en los pacientes con EB en función del tratamiento de mantenimiento recibido, médico o quirúrgico. MÉTODOS: Estudio retrospectivo de pacientes con diagnóstico endoscópico e histológico de EB. Un grupo de pacientes recibió tratamiento médico con inhibidores de la bomba de protones (IBP) y otro grupo fue sometido a intervención quirúrgica (funduplicatura de Nissen). Se compararon datos epidemiológicos y resultados de pHmetría (tiempo de pH < 4, reflujos prolongados > 5 min, puntuación de DeMeester) de cada grupo. La pH-metría se realizó con IBP en el grupo de tratamiento médico y en el grupo de cirugía sin consumo de antisecretores ácidos. Se definió fracaso del tratamiento como un pH < 4 total superior al 5%. RESULTADOS: Fueron incluidos 128 pacientes con EB (tratamiento médico 75, tratamiento quirúrgico 53). Ambas cohortes eran homogéneas respecto a sus características demográficas. Las puntuaciones de DeMeester, fracción de tiempo de pH < 4 y cantidad de reflujos prolongados fueron significativamente inferiores en los pacientes con funduplicatura frente a los que recibían IBP (p < 0,001). De forma global se apreció un fracaso de tratamiento en el 29% de los pacientes, que fue significativamente mayor en el grupo de tratamiento médico (40% vs 13%; p < 0,001). CONCLUSIONES: El grado de control del reflujo ácido gastroesofágico es subóptimo en un elevado porcentaje de pacientes con EB. El tratamiento médico ofrece resultados inferiores a la cirugía antirreflujo y se debería intentar optimizar sus resultados
INTRODUCTION: Barrett's oesophagus (BE) is an oesophageal injury caused by gastroesophageal acid reflux. One of the main aims of treatment in BE is to achieve adequate acid reflux control. OBJECTIVE: To assess acid reflux control in patients with BE based on the therapy employed: medical or surgical. METHODS: A retrospective study was performed in patients with an endoscopic and histological diagnosis of BE. Medical therapy with proton pump inhibitors (PPI) was compared with surgical treatment (Nissen fundoplication). Epidemiological data and the results of pH monitoring (pH time < 4, prolonged reflux > 5min, DeMeester score) were evaluated in each group. Treatment failure was defined as a pH lower than 4 for more than 5% of the recording time. RESULTS: A total of 128 patients with BE were included (75 PPI-treated and 53 surgically-treated patients). Patients included in the two comparison groups were homogeneous in terms of demographic characteristics. DeMeester scores, fraction of time pH < 4 and the number of prolonged refluxes were significantly lower in patients with fundoplication versus those receiving PPIs (P < .001). Treatment failure occurred in 29% of patients and was significantly higher in those receiving medical therapy (40% vs 13%; P < .001). CONCLUSIONS: Treatment results were significantly worse with medical treatment than with anti-reflux surgery and should be optimized to improve acid reflux control in BE. Additional evidence is needed to fully elucidate the utility of PPI in this disease
