Replacement of the main bile duct by bioprosthesis in an experimental porcine model (24-month results).

Background: Cholecystectomy for conditions like iatrogenic injury during cholecystectomy can lead to complications such as bile duct injuries, necessitating alternative options like bioprosthesis.

Methods: This study evaluated a bioprosthesis's efficacy in maintaining bile duct continuity over 24 months in 16 male pigs.

Results: The bioprosthesis was implanted in the common bile duct of three-month-old animals, with follow-ups at 1, 6, 12, 18, and 24 months.

Development of a biodegradable prosthesis through tissue engineering, for the organ-replacement or substitution of the extrahepatic bile duct.

Introduction And Objectives: There are different situations in which an extrahepatic bile duct replacement or substitute is needed, such as initial and localized stages of bile duct cancer, agenesis, stenosis, or bile duct disruption.

Materials And Methods: A prosthesis obtained by electrospinning composed of Poly (D,L-lactide-co-glycolide) (PGLA) - Polycaprolactone (PCL) - Gelatin (Gel) was developed, mechanical and biological tests were carried out to evaluate resistance to tension, biocompatibility, biodegradability, cytotoxicity, morphological analysis and cell culture. The obtained prosthesis was placed in the extrahepatic bile duct of 15 pigs with a 2-year follow-up.

[Comparación entre ligadura con lazo hemostático y engrapadora mecánica lineal para el cierre de base apendicular].

IntroducciÓn: En las últimas décadas es creciente el abordaje por mínima invasión de patologías abdominales debido a sus beneficios evidentes. El cuadro apendicular es la principal emergencia quirúrgica, con diferentes métodos del cierre de la base apendicular. En este artículo comparamos dicho cierre con engrapadora lineal o ligadura con lazo hemostático, para analizar la frecuencia de complicaciones como absceso, dehiscencia y seroma.

Hepatic Metastasis from Colorectal Cancer.

The liver is the most common site of metastasis in patients with colorectal cancer due to its anatomical situation regarding its portal circulation. About 14 to 18% of patients with colorectal cancer present metastasis at the first medical consultation, and 10 to 25% at the time of the resection of the primary colorectal cancer. The incidence is higher (35%) when a computed tomography (CT) scan is used.

Updates in Mirizzi syndrome.

Mirizzi syndrome, known as extrinsic bile compression syndrome, is a rare complication of cholecystitis and chronic cholelithiasis, secondary to the obliteration of the infundibulum of the gallbladder or cystic duct caused by the impact of one or more calculations in these anatomical structures, which leads to compression of the adjacent bile duct, resulting in partial or complete obstruction of the common hepatic duct, triggering liver dysfunction. Our aim is to identify and describe the current epidemiology, diagnostic methods, and treatment of Mirizzi syndrome. A literature search was performed using different databases, including Medline, Cochrane, Embase, Medscape, PubMed, using keywords: Mirizzi syndrome, epidemiology, markers, pathophysiology, clinical presentation, diagnosis, and treatment.

[The importance of master's degree and doctorate degree in general surgery].

Background: The Doctor of Philosophy is the highest academic degree that can be obtained in universities. Graduate Education Program in Medicine in Mexico is divided into 2 major categories: Medical Specialty and Master studies/Doctor of Philosophy. The objective of this study was to demonstrate the importance of master's degrees and Doctor of Philosophy in general surgery.
