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.

La bibliometría es la aplicación de métodos estadísticos para analizar libros, artículos y otras publicaciones, especialmente científicos. Muy relacionada con la cienciometría e informetría, al punto de superponerse y confundirse. La bibliometría se refiere al estudio de la dinámica de las disciplinas reflejado en la producción de su literatura. Incluye desde el registro de cambios en la producción de una disciplina académica a lo largo del tiempo y entre países, hasta el problema de la colección bibliotecaria.En este artículo se explicarán algunos conceptos históricos, definiciones y objetivos de la bibliometría; así como las Leyes de la bibliometría; los tipos de análisis e indicadores bibliométricos más utilizados; para terminar con algunos ejemplos de diferentes tipos de estudios bibliométricos publicados, para que el lector pueda formarse una idea general de lo que puede hacer en este campo, aplicando estas metodologías a disciplinas quirúrgicas y otras también.El objetivo de este manuscrito fue generar un documento de estudio respecto de la bibliometría como alternativa para desarrollar investigación en cirugía y disciplinas afines.

The integration of new technologies has shown potential to enhance self-care practices among patients with diabetic foot ulcers (DFUs). Understanding the effectiveness of these interventions can inform clinical and public health strategies to prevent complications and improve patient outcomes. This scoping review aims to assess the impact of digital and educational technologies on self-care practices and health outcomes in individuals with diabetic foot ulcers. Databases searched encompassed EMBASE, MEDLINE, SciELO, WoS, Scopus, and PubMed, covering publications up to September 2024. The search strategy incorporated MeSH terms and keywords related to “self-care,” “diabetic foot ulcers,” and “educational technology.” After duplicate removal, titles and abstracts were screened independently by three reviewers. Full texts of selected articles were analyzed, and data regarding study design, interventions, outcomes, and populations were extracted using standardized forms. Discrepancies were resolved by consensus. From 442 identified records, 12 studies met inclusion criteria, primarily highlighting the role of mobile applications and digital educational tools in enhancing self-care behaviors, adherence, and complication prevention. Positive effects on patient knowledge and routine adherence were frequently reported. Technological interventions show promise in improving self-care among DFU patients; however, further high-quality, longitudinal studies are needed to establish best practices and long-term benefits.

Acute gastric volvulus (AGV), is an uncommon complication of large paraesophageal hernias (PEH), resulting in closed-loop obstruction that may lead to incarceration and strangulation. The aim of this study was to summarize the evidence on clinical characteristics, surgical treatment, postoperative complications (POC), recurrence, and 30-day mortality (30DM), in patients undergoing surgery for AGV secondary to PEH. A systematic review including studies on AGV secondary to PEH was conducted. Searches were performed in WoS, Embase, Medline, Scopus, BIREME-BV and SciELO. Primary outcomes included POC, 30DM and recurrence. Secondary outcomes comprised publication date, study origin and design, number of patients, volvulus type, hospital stay length, treatments; and methodological quality (MQ) of studies assessed using MInCir-T and MInCir-Pr2 scales. Descriptive statistics, weighted averages (WA), least squares logistic regression for comparisons, and meta-analysis of POC prevalence and HM were applied. Of 1049 studies 171 met selection criteria, encompassing 15,178 patients. The WA age of patients was 75.3 ± 13.9 years, with 51.3% female. Most studies originated from USA (31.6%), with 52.6% published in the last decade. The WA of hospital stay was 7.9 ± 5.3 days. Among patients, 32.0% experienced POC, 7.6% required reinterventions and HM was 5.7%. MQ scores averaged 8.9 ± 2.3 (MInCir-T) and 13.4 ± 5.4 (MInCir-Pr2). When comparing 1990–2014 and 2015–2024 periods, there were significant differences in age, reinterventions, readmissions and recurrence rates. Despite surgical and resuscitative advancements, AGV prognosis remains poor, with high POC rates, prolonged hospitalization and significant 30DM. These findings emphasize the importance of early diagnosis and timely intervention for acute PEH to improve surgical outcomes.

Background: Hepatic cystic echinococcosis (HCE) remains a significant public health issue in endemic countries. Although recurrence is a recognized challenge, its independent impact on adverse clinical outcomes such as postoperative complications (POC), mortality, and length of hospital stay (LHS) remains poorly studied in Latin America. This study aimed to assess the risk of POC, mortality, and LHS in patients with recurrence of HCE. Methods: We conducted a retrospective cohort study of patients who underwent surgery for HCE between 1993 and 2019 at two centers in southern Chile. Patients with recurrence (exposed group) were compared to those undergoing primary surgery (non-exposed group). The primary outcome was the presence of POC; secondary outcomes included mortality and LHS. Crude and adjusted relative risks (RR) with 95% confidence intervals were estimated using Poisson regression with robust errors. Linear regression models were applied to assess the effect of recurrence on LHS. Results: A total of 154 patients with 271 cysts were included. Recurrence was identified in 43 patients (27.9%). POC occurred in 18.2% of the total cohort and were significantly more frequent in the recurrence group (41.9% vs. 9.0%, p < 0.001). Adjusted RR for POC in the presence of recurrence was 5.1 (95% CI 2.7–9.9). Mortality was higher in patients with recurrence (7.0% vs. 2.7%, RR: 2.6; 95% CI 0.5–12.3), though not statistically significant. LHS was 1 day longer in the recurrence group (7.3 ± 4.5 vs. 5.6 ± 3.4; p = 0.02), but this association lost significance in regression models. Conclusions: Recurrence of HCE increases the risk of POC. While trends toward higher mortality and prolonged LHS were observed, these did not reach statistical significance. These findings underscore the importance of long-term follow-up and the need to identify prognostic factors for recurrence to optimize outcomes in patients with HCE in endemic regions. Graphical
