RESUMO
Adipose-derived stem cells comprise several clinically beneficial qualities that have been explored in basic research and have motivated several clinical studies with promising results. After being approved in the European Union, UK, Switzerland, Israel, and Japan, allogeneic adipose-derived stem cells (darvadstrocel) have been recently granted a regenerative medicine advanced therapy (RMAT) designation by US FDA for complex perianal fistulas in adults with Crohn's disease. This huge scientific step is likely to impact the future spread of the indications of allogeneic adipose-derived stem cell applications. The current knowledge on adipose stem cell harvest describes quantitative and qualitative differences that could be influenced by different donor conditions and donor sites. In this comprehensive review, we summarize the current knowledge on the topic and propose donor profiles that could provide the optimal initial quality of this living drug, as a starting point for further applications and studies in different pathological conditions.
RESUMO
La tecnología constituye uno de los pilares de la cirugía del siglo XXI y resulta un factor clave para la consecución de unos mejores resultados quirúrgicos. El proceso quirúrgico actual lleva implícito no solo la técnica operatoria, sino un grado de especialización muy elevado y el conocimiento y empleo de técnicas y dispositivos propios de otros campos. En España no existen estudios publicados a nivel nacional a este respecto.Desde la Sección de Cirugía Mínimamente Invasiva e Innovación Tecnológica (CMI-IT) de la Asociación Española de Cirujanos hemos diseñado un estudio cuyo objetivo principal es evaluar el grado de implantación tecnológica en la especialidad de cirugía general en España, así como analizar los dispositivos disponibles en los diferentes centros del país. Nos planteamos realizar una descripción pormenorizada de las aplicaciones de dichos dispositivos y técnicas por áreas de interés, señalando las patologías y procedimientos en los que se utiliza dicha tecnología.

RESUMO
Diseases of the digestive tract are complex and encompass a broad spectrum of different pathogeneses (inflammatory, ischemic, neoplastic, and functional deficit). The digestive tract is not a sterile environment, and its organs are composed of tissues with different embryologic origin and different morphologic and functional complexity. As a consequence, the management of these diseases is often challenging. Stem cell (SC) therapy has yielded some promising results in preclinical studies, and, recently, some approaches have been tested clinically. Indeed, during the last 5 years, the number of clinical trials with SCs for treatment of digestive tract diseases has increased 10-fold. The most advanced programs involve liver failure, Crohn's disease, and fistulous disease and are now in phase III of development. If progress continues and the preliminary results are confirmed, SC therapy will become a clinical reality in the near future. In this review we examine the basic concepts of the SC therapy, analyze the potential benefits of SCs in diseases of the digestive tract, and summarize current experience in the field and the future perspectives.
