    Hernia de Petersen como complicación tardía del Bypass Gástrico. Revisión Sistemática
    (Universidad Católica de Cuenca., 2023) Calle León , Richye Santiago; Ávila Narvaez, Jorge Eduardo; 0302413596
    Abstract: Petersen's hernia (PH) is a late complication in the Gastric Bypass bariatric procedure. It is characterized by the protrusion of intestinal loops into the mesenteric defect, primarily located between the alimentary limb and the transverse mesocolon; it can lead to some complications such as obstruction, ischemia, and perforation, highlighting the importance of timely and accurate diagnosis and problems identification. Objective: To determine Petersen's hernia as a late complication of Gastric Bypass through a systematic review. Methodology: Out of 1588 studies were reviewed; after applying filters, 121 studies were selected, 97 were duplicates, and eight did not meet the criteria; finally, 16 were included. Results: PH maintains an incidence of 0.6 to 4% in post-gastric bypass patients, computed tomography shows a sensitivity of 60% to 80% and a specificity of 67% to 94%, the mesenteric whirl sign obtained a sensitivity of 75% and specificity of 85%, complications following the occurrence of Petersen's hernia included chylous ascites, mechanical ileus, mesenteric ischemia, obstructive processes, and even gastric perforation. Conclusions: The incidence of PH in Gastric Bypass patients remained at a relatively low percentage, between 0.6% and 4%; among imaging studies, computed tomography is the most commonly used diagnostic predictor, with several imaging findings identified. The mesenteric whirl sign exhibits the highest sensitivity and specificity. Post-surgical complications include chylous ascites, mechanical ileus, mesenteric ischemia, obstructive processes, and gastric perforation.

    Validez de los criterios de severidad en pancreatitis aguda
    (Universidad Católica de Cuenca., 2023) Villavicencio Reyes, Doménica Sarahí; Ávila Narvaez, Jorge Eduardo; 0350194429
    Background: Acute pancreatitis is a frequently occurring pathology worldwide, leading to an inflammatory process that can result in multiple organ failure and a high mortality rate. Opportune and appropriate treatment are essential to prevent negative consequences on individuals' quality of life. Severity criteria for the disease are a pivotal element in implementing necessary procedures to reduce symptoms and prevent organ dysfunction. Objective: To analyze the validity of the severity criteria for acute pancreatitis. Methodology: The methodology was of qualitative approach, descriptive scope, bibliographic-documentary type, and non-experimental design. For review articles selection, inductive-deductive methods and the PRISMA matrix were employed. Conclusions: The APACHE II and BISAP scales have been established as the most prominent scales in most articles reviewed for stratifying acute pancreatitis; despite being older, APACHE II remains the favorite scale used by medical staff worldwide and is considered the most accurate and sensitive predictor.
