ABSTRACT

BACKGROUND: Cholangiohydatidosis (CH) is an evolutionary complication of hepatic cystic echinococcosis, associated with increased morbidity and mortality. The aim of this study was to describe the available evidence regarding clinical characteristics of CH, postoperative complications and hospital mortality. METHODOLOGY/PRINCIPAL FINDINGS: Systematic review. Studies related to CH with no language or publication restriction were included. Sensitive searches were performed in Trip Database, SciELO, BIREME-BVS, WoS, PubMed, EMBASE and SCOPUS. MeSH and free terms were used, including articles up to April 2023. The main outcome variables were postoperative complications and hospital mortality; the secondary ones were publication year, origin and design of primary studies, main clinical manifestation, anatomical location and type of cysts, hospital stay, surgical procedure performed, reinterventions; and methodological quality of primary studies, which was assessed using MInCir-T and MInCir-P scales. Descriptive statistics, calculation of weighted averages and their comparison by least squares logistic regression were applied. 446 studies were retrieved from the searches performed, 102 of which met the inclusion and exclusion criteria. The studies analyzed represent 1241 patients. The highest proportion of articles was published in the last decade (39.2%). Reports are mainly from Turkey (28.4%), Greece (9.8%), Morocco and Spain (8.8% each). With a weighted mean of 14.3 days of hospital stance; it was verified that 26.2% of patients developed postoperative complications (74,3% Clavien y Dindo III y IV), 6.7% needed re-interventions, and 3.7% died. When comparing the variables age, postoperative complications, hospital mortality, and reinterventions in two periods of time (1982-2006 vs. 2007-2023), no statistically significant differences were found. When applying the MInCir-T and MInCir-P scales, the methodological quality of the primary studies was 9.6±1.1 and 14.5±4.3 points, respectively. CONCLUSION/SIGNIFICANCE: CH is associated with severe postoperative complications and significant hospital mortality, independent of the development of therapeutic support associated with the passage of time.

ABSTRACT

Lograr determinar el volumen total de un hígado (VHT), o volumetría hepática, pasa a ser de relevancia en diversas situaciones, tales como, vigilancia del progreso de una enfermedad de carácter crónico, planificación de resecciones y trasplantes hepáticos; y observación del clearance hepático de algunos fármacos hepatotropos. La VHT se puede realizar utilizando métodos de segmentación en el curso de una tomografía computarizada (TC), ya sean estos manual, automáticos, y semiautomáticos; mediante resonancia nuclear (RN), utilizando softwares de distintas generaciones (1ª a 4ª). La medición de VHT está indicada en pacientes sometidos a resecciones hepáticas mayores, en el contexto del tratamiento de neoplasias (carcinoma hepatocelular, colangiocarcinoma, metástasis hepáticas o tumores benignos de gran tamaño), abscesos (piogénicos, amebianos), y después de un traumatismo hepático complejo; así como también en la etapa preoperatoria de un trasplante hepático. El objetivo de este manuscrito fue generar un documento de estudio sobre métodos para determinar volumetría hepática.


SUMMARY: Being able to determine the total hepatic volume (THV), or THV, becomes relevant in various situations, such as monitoring the progress of a chronic disease, planning resections and liver transplants; and observation of the hepatic clearance of some hepatotropic drugs. THV can be performed using segmentation methods in the course of a computed tomography (CT), whether manual, automatic, or semi-automated; by nuclear resonance (NR), using software from different generations (1st to 4st). THV measurement is indicated in patients undergoing major liver resections, in the context of treatment of neoplasms (hepatocellular carcinoma, cholangiocarcinoma, liver metastases or large benign tumors), abscesses (pyogenic, amoebic), and after liver trauma complex, as well as in the preoperative stage of a liver transplant. The aim of this manuscript was to generate a study document regarding methods for determine hepatic volumetry.

ABSTRACT

La expansión y consolidación de la práctica clínica basada en la evidencia ha llevado entre otras, a la necesidad de realizar una variedad cada vez mayor de tipos de revisión de la literatura científica; lo que permite avanzar en el conocimiento y comprender la amplitud de la investigación sobre un tema de interés, teniendo en cuenta que una de las propiedades del conocimiento es su carácter acumulativo. Sin embargo, la diversidad de la terminología utilizada genera confusión de términos y conceptos. El objetivo de este manuscrito fue proporcionar un listado de los tipos de revisiones de la literatura más frecuentemente utilizados con sus características y algunos ejemplos de ellas. Revisión cualitativa. Se examinaron de forma dirigida las bases de datos PubMed, WoS y Scopus, en búsqueda de términos asociados a tipos de revisiones y síntesis de la literatura científica. Se encontraron 21 tipos de revisión; y 29 variantes y sinonimias asociadas; las que ilustran los procesos de cada una de ellas. Se da una descripción general de las características de cada cual, junto con las fortalezas y debilidades percibidas. No obstante, se verificó que sólo algunos tipos de revisión poseen metodologías propias y explícitas. Este enfoque, proporciona un punto de referencia para quienes realizan o interpretan revisiones en el ámbito sanitario, y sugiere dos tipos de propuestas de clasificación.


SUMMARY: The expansion and consolidation of evidence-based clinical practice has led, among other things, to the need to carry out an increasing variety of types of literature reviews, which allows advancing in knowledge and understanding the breadth of research on a topic of interest. However, the diversity of the terminology used generates confusion of terms and concepts. The aim of this manuscript was to provide a list of the most frequently used review types with their characteristics and some examples. Qualitative review. PubMed, WoS and Scopus databases were examined in a directed way, searching for terms associated with types of reviews and syntheses of the scientific literature. Twenty-one types of review, and 29 variants and associated synonymies were found; those that illustrate the processes of each of them. An overview of the characteristics of each is given, along with perceived strengths and weaknesses. However, it was verified that only some types of review have their own explicit methodologies. This approach, provides a point of reference for those who perform or interpret reviews in the health field and suggests two classification proposals.
