RESUMO
BACKGROUND: Gallstone ileus (GI) represents a rare cause of mechanical intestinal occlusion, which is caused by the impaction of a gallstones at the gastrointestinal tract, being most frequently the terminal ileum; its etiology is due to the passage of a calculum through a biliary-enteric fistula. Due to its low incidence, diagnostic suspicion and adequate initial surgical treatment are essential for an adequate clinical evolution. OBJECTIVE: A bibliographic review on the current surgical management of GI was carried out and exemplified by the presentation a clinical case. CLINICAL CASE: 78-year-old male with bowel obstruction, upon undergoing a CT scan, a gallstone at the level of distal ileum is displayed, therefore, an exploratory laparotomy (ex lap) is performed with enterotomy and extraction of the calculus. The patient bestowed adequate postoperative clinical evolution, and the presence of a cholecystoduodenal fistula is documented by an upper endoscopy. DISCUSSION: GI represents an uncommon pathology, however, there is discrepancy in the literature regarding the initial surgical management, especially in whether or not a biliary procedure should be associated with emergency enterolithotomy. CONCLUSION: GI is associated with complications secondary to diagnostic delay and its late surgical resolution, although the initial treatment is aimed at resolving the intestinal obstruction through enterotomy and gallstone extraction, there is controversy regarding the preferred time for cholecystectomy and repair of biliary-enteric fistula, being the two-stage surgery the surgical procedure of choice, especially in patients with a high risk of complications.
ANTECEDENTES: El íleo biliar (IB) es una causa poco frecuente de oclusión intestinal mecánica, causado por la impactación de un cálculo biliar en el tubo digestivo, siendo la localización más frecuente el íleon terminal; se debe al paso de un cálculo a través de una fístula bilioentérica. Debido a su baja incidencia, la sospecha diagnóstica y el tratamiento quirúrgico inicial adecuado son de gran importancia para la evolución clínica. OBJETIVO: Realizar una revisión bibliográfica sobre el manejo quirúrgico actual del IB y ejemplificarlo mediante la presentación de un caso clínico. CASO CLÍNICO: Varón de 78 años con cuadro de oclusión intestinal, con presencia de cálculo biliar en el íleon distal por tomografía. Se realiza laparotomía exploradora con enterotomía y extracción del cálculo. Cursa con adecuada evolución posquirúrgica, documentándose fístula colecistoduodenal por panendoscopia. DISCUSIÓN: El IB es una patología poco común, por lo cual existe discrepancia en cuanto al tipo de manejo quirúrgico ideal, sobre todo en si se debe o no asociar un procedimiento biliar a la enterolitotomía de urgencia. CONCLUSIÓN: El IB se asocia a complicaciones secundarias al retraso diagnóstico y a una mala elección de la técnica quirúrgica inicial. Si bien el tratamiento está encaminado a resolver la obstrucción intestinal mediante enterotomía y extracción del cálculo biliar, existe controversia en cuanto al tiempo preferido para realizar la colecistectomía y la reparación de la fístula bilioentérica, siendo la cirugía en dos tiempos el procedimiento quirúrgico de elección, sobre todo en pacientes con alto riesgo de complicaciones.

BACKGROUND AND OBJECTIVES: Patients receiving >=80% of their energy requirements by enteral nutrition (EN) have better clinical outcomes; unfortunately, there are discrepancies between the amount prescribed and amount received. The aim of this study was to explore the nutritional clinical practice, determine the adequacy and identify reasons for underfeeding. METHODS AND STUDY DESIGN: A retrospective study was conducted in hospitalized, non-intensive care unit, adult patients receiving EN for >=72 h. The following data were recorded: the prescribed target of energy and protein per day, daily energy intake, and the percentage of adequacy of the energy and protein requirement up to hospital day seven. Complications during administration or reasons for interruption and the proportion of patients who received >=80% of the energy goals on days four and seven were also recorded. RESULTS: In total, 52 patients were included (61.5% women), with a median age of 57.5 years; 20.4% and 6.1% of the patients received >=80% of their energy and protein goals, respectively, on day four, which improved to 28% (p<0.005) and 19% (p<0.001), respectively, on day seven. During the first seven days, a statistically significant (p<0.001) difference was observed between the amount of prescribed and administered energy over 24 h. The patients who received <80% of their total energy requirement remained hospitalized for 29 days (IQR 16.5-45.5), while those who received >=80% were hospitalized for 18 days (IQR 13.3-28.8) (p<0.05). CONCLUSIONS: Significant energy and protein deficits were documented. Furthermore, it is necessary to use strategies such as the implementation of an algorithm to optimize EN.
