Diagnóstico y tratamiento de la enfermedad diverticular del colon derecho: revisión de conjunto / Diagnosis and management of right colonic diverticular disease: A review

El objetivo de esta revisión es definir las características clínico-patológicas y aclarar el tratamiento de la enfermedad diverticular del colon derecho. Es poco frecuente en Europa, Estados Unidos y Australia, y más común en Asia. Durante los últimos años, su incidencia ha aumentado en Occidente, con diferentes distribuciones entre poblaciones. Muchos estudios han mostrado que es difícil diferenciar antes de la cirugía los síntomas de presentación de esta enfermedad de los de la apendicitis, ya que los síntomas y signos son similares, por lo que no es infrecuente encontrarse con un diagnóstico incorrecto. Con estudios de diagnóstico por la imagen exactos es posible establecer un diagnóstico preoperatorio preciso a fin de evaluar una estrategia de tratamiento adecuada. Actualmente, el tratamiento de esta enfermedad no está bien definido, no se han propuesto recomendaciones claras y no se sabe si también se pueden aplicar las recomendaciones para la enfermedad diverticular del colon izquierdo. Varios autores han señalado que el tratamiento conservador es el mejor enfoque, incluso en caso de reincidencia, y que la cirugía solo estaría indicada en determinados casos

The aim of this narrative review is to define the clinical-pathological characteristics and to clarify the management of right colonic diverticular disease. It is rare in Europe, USA and Australia and more common in Asia. In the recent years its incidence has increased in the West, with various distributions among populations. Many studies have reported that it is difficult to differentiate the presenting symptoms of this disease from those of appendicitis before surgery, because the signs and symptoms are similar, so misdiagnosis is not infrequent. With accurate imaging studies it is possible to reach a precise preoperative diagnosis, in order to assess an accurate treatment strategy. Currently the management of this disease is not well defined, no clear guidelines have been proposed and it is not known whether the guidelines for left colonic diverticular disease can also be applied for it. Several authors have stated that conservative management is the best approach, even in case of recurrence, and surgery should be indicated in selected cases

The UDCA dosage deficit: a fate shared with CDCA.

Ursodeoxycholic acid (UDCA) is used both as the treatment of choice in many cholestatic syndromes and as complementary therapy in many liver diseases. However, few dose-finding studies exist, and none has evaluated the efficacy and long-term safety of UDCA therapy in primary biliary cirrhosis (PBC). There is an open debate about UDCA's impact on the natural history of PBC, and no universal evidence of benefits on the major endpoint exists. This is perhaps due to a UDCA dosage deficit. Most clinical trials on PBC therapy have used conservative dosages of UDCA similar to those of chenodeoxycholic acid (CDCA) used for dissolution of gallstones. It may be necessary to re-evaluate the dosage of UDCA that provides the most effective treatment.
