ABSTRACT
Background and aim: Recurrent biliary pancreatitis is described as episodes of new abdominal pain after diagnosis of pancreatitis. Few studies have analyzed the abdominal pain before the diagnosis of acute pancreatitis. Our study aimed to analyze factors associated with previous abdominal pain episodes in patients with biliary pancreatitis, and elucidate its possible pancreatic origin. Methods: Data from direct interrogation and medical records was analyzed from 48 hospitalized female patients with diagnosis of acute biliary pancreatitis. Results: Mean age of our patients was 31.6 years (SD+13.9). Forty one (85.4%) patients gave history of at least one previous abdominal pain episode. During the episode 37 (90.2%) patients received H2 receptor antagonist or proton pump inhibitors as treatment; 26 (63.4%) had epigastric pain; 23(56.1%) gave association with cholecystokinetic food; 21 (51.2%) complained of nausea and/or vomiting; 23 (56.1%) had jaundice, acholia and/or dark urine; and 20 (48.9%) patients had microlithiasis and/or biliary sludge. Conclusions: Previous abdominal pain episodes had similar characteristics to a pancreatic episode in a high percentage of our patients. These characteristics suggest that these episodes are often undiagnosed pancreatic attacks.
ABSTRACT
Objetivo: Describir nuestra experiencia quirúrgica en pacientes en diálisis, centrándose en la identificación de factores de riesgo perioperatorios (30 días) para morbilidad y mortalidad. Sede: CMN Adolfo Ruiz Cortines, Unidad Médica de Alta Especialidad 189, del Instituto Mexicano del Seguro Social, Veracruz, México. Diseño: Observacional, descriptivo, retrospectivo, transversal. Análisis estadístico: Desviación estándar y rango, método de la Chi-cuadrada (χ²) y el test de Mantel-Haenszel, análisis multivariado de regresión logística lineal. Material y métodos: Estudio retrospectivo de 6 años de revisión de casos y controles de 108 pacientes en diálisis sometidos a cirugía. El grupo de casos incluyó pacientes que sufrían una complicación o muerte. Los factores de riesgo evaluados: edad, género, índice de masa corporal, diabetes, tipo de diálisis, cirugía de emergencia, hemoglobina, urea, creatinina, albúmina y estancia hospitalaria. Resultados: La cirugía más común fue plastía de hernias de pared abdominal (n = 64), cirugía gastrointestinal (n = 18) y colecistectomía laparoscópica (n = 8). La tasa de morbilidad y mortalidad fue 25 y 9.3%, respectivamente. Los factores de riesgo identificados en análisis univariado (p < 0.05) fueron cirugía de emergencia, nivel bajo de hemoglobina, albúmina baja y estancia hospitalaria. El análisis multivariado confirmó la albúmina baja y estancia hospitalaria (p < 0.02) como factores de riesgo de morbilidad y mortalidad. Conclusiones: Los pacientes en diálisis tienen alta tasa de complicaciones y mortalidad después de la cirugía, que se relaciona con factores que dan pobres resultados, los cuales podrían ser corregidos con el fin de mejorar la morbilidad y la mortalidad.
Objective: To describe our surgical experience with patients undergoing dialysis, addressing the identification of perioperative (30 days) risk factors for morbidity and mortality. Setting: CMN Adolfo Ruiz Cortines, Unidad Médica de Alta Especialidad 189, of the Instituto Mexicano del Seguro Social [High Speciality Medical Unit of the Mexican Institute of Social Welfare], in Veracruz, Mexico. Design: Observational, descriptive, retrospective, cross-sectional study. Statistical analysis: Standard deviation and range, Chi square (χ²) and Mantel-Haenszel test. Linear logistic regression multivariate analysis. Material and methods: A six-year retrospective study of cases and controls reviewing 108 patients undergoing dialysis and subjected to surgery. The group of cases included patients with complications or who died. Assessed risk factors were: age, gender, body mass index, diabetes, type of dialysis, emergency surgery, hemoglobin, urea, creatinine, albumin, and in-hospital stay. Results: The most common surgeries were abdominal wall hernia repair (n = 64), gastrointestinal surgery (n = 18), and laparoscopic cholecystectomy (n = 8). Rates of morbidity and mortality were 25 and 9.3%, respectively. The identified risk factors through the multivariate analysis (p < 0.05) were emergency surgery, low hemoglobin level, low albumin, and in-hospital stay. Multivariate analysis confirmed low albumin and in-hospital stay as risk factors (p < 0.02) for morbidity and mortality. Conclusions: Patients undergoing dialysis have a high rate of complications and mortality after surgery related to factors that yield poor results, which could be corrected to improve the morbidity and mortality rates.
