Background: The term chronic appendicitis has been used to describe any type of chronic pain that originates in the appendix, with or without inflammation. This broad category can be divided more specifically into: chronic or recurrent appendicitis and appendiceal colic pain. Clinical case: a 41-year-old female, suffering intestinal chronic constipation, abdominal pain, nausea, hiporexia and febricula, treated with antibiotics, vermifuges, analgesics and antispasmodics, showing a slight and partial improvement. She was suffering chronic pain in lower abdomen, mostly on the right side along a year. With these symptoms, she underwent an exploratory laparotomy, that showed chronic appendicitis. Appendix had been removed. The histopathological report corresponded to chronic appendicitis. Conclusions: the histopathological characteristics and the clinical manifestations of the chronic appendicitis are different from those of acute appendicitis. Criteria for chronic appendicitis include: symptoms lasting longer than 4 weeks, confirmation of chronic swelling through histopathological examination, improvement of symptoms after appendectomy. The ultrasonic images, the barium enema and the computerized helicoidal tomography could be suggestive for its diagnosis. [ABSTRACT FROM AUTHOR]

Objetivo: Comparar la seguridad y la eficacia de la atención fast-track vs. atención convencional en apendicitis no complicada en un hospital pediátrico., Método: Ensayo clínico controlado, aleatorizado, con dos grupos de 30 pacientes cada uno: A) fast-track, apendicitis no complicada que cumplieron el programa; y B) atención convencional, apendicitis no complicada con atención habitual. Variables de seguridad y eficacia: proporción de complicaciones y tiempo de estancia hospitalaria., Resultados: Se incluyeron 60 pacientes, sin diferencia entre grupos: sexo masculino (53 vs. 60%), edad (8 ± 3 vs. 8 ± 2 años), tiempo de evolución (23 ± 21 vs. 24 ± 20 horas), tiempo desde ingreso a urgencias hasta inicio de cirugía (6 ± 4 vs. 8 ± 6 horas), y tipo de apendicitis edematosa (27 vs. 24%) o supurada (73 vs. 76%). La estancia hospitalaria promedio del grupo fast-track fue de 13 ± 5 vs. 72 ± 40 horas del grupo de atención convencional (p = 0.001). Hubo complicaciones en el 3 y el 6%, respectivamente (p = 1.0). La estancia hospitalaria disminuyó 2.45 días por paciente con el protocolo fast-track, lo que representa un ahorro de $ 6,731 pesos/día/paciente/hospitalización (US$ 373), sin un aumento de las complicaciones., Conclusión: El protocolo fast-track en los niños con apendicitis no complicada es seguro y efectivo en un hospital universitario. El programa fast-track aportó beneficios clínicos y económicos, ahorrando en total $ 403,860 en los 30 pacientes., Objective: To compare safety and efficacy of fast-track program vs. conventional attention in non-complicated appendicitis attending a pediatric university hospital., Method: Randomized clinical trial, comparing two groups with 30 patients each: (A) fast-track group, appendicitis agreeing the treatment protocol; and (B) conventional attention group, appendicitis following habitual surgical care. The efficacy and safety measures were length of hospital stay and proportion of complications., Results: We included 60 patients, there were no significant difference between groups with regard: male gender (53 vs. 60%), age (8 ± 3 vs. 8 ± 2 years-old), time of evolution (23 ± 21 vs. 24 ± 20 h), time since admittance to emergency and beginning of surgery (6 ± 4 vs. 8 ± 6 h), and type of appendicitis edematous (27 vs. 24%) or suppurate (73 vs. 76%). Mean length of hospital stay in fast-track group was 13 ± 5 vs. 72 ± 40 h in conventional attention (p = 0.001). The complications were 3 and 6%, respectively (p = 1.0). Fast-track program diminished length of hospital stay in 2.45 days per patient, representing a mean cost saving of 6,731 Mexican pesos per day, per patient hospitalized (US$ 373), without increased complications., Conclusion: Fast-track program in children with non-complicated appendicitis is safe and effective in pediatric university hospital; there was cost-minimization without carelessness of safety. This program support clinical and economic benefits, a total saving of 403,860 Mexican pesos for the 30 patients in the fast-track group., (Copyright: © 2018 Permanyer.)
