Ultrasonography is not the most cited imaging technique for the evaluation of infectious and neoplastic diseases of the gastrointestinal tract and the peritoneum, but it is often the initial technique used in the initial workup for nonspecific clinical syndromes. Despite its limitations, ultrasonography’s strengths enable it to provide meaningful diagnostic information.

To discuss the most important ultrasonographic, clinical, and epidemiological findings for infectious disease, we follow a topographical approach: stomach (Anisakis), proximal small bowel (Giardia lamblia, Strongyloides stercoralis, Mycobacterium avium-intracellulare complex, and Cryptosporidium), distal small bowel (Yersinia, Salmonella, and Campylobacter), terminal ileum and cecum (tuberculosis), right colon (Entamoeba histolytica), left colon (Shigella), sigmoid colon and rectum, pancolitis (Clostridium difficile, Cytomegalovirus, and Escherichia coli), and peritoneum.

To discuss the ultrasonographic and clinical findings of the most common neoplastic diseases, we follow a nosological approach: polyploid lesions as precursors of tumors, carcinomas, neuroendocrine tumors, hematological tumors, mesenchymal tumors, and metastases. We briefly discuss tumors of the peritoneum and the use of ultrasonography to guide percutaneous biopsy procedures.

La ecografía no es la técnica de imagen más citada para la valoración de la patología infecciosa y tumoral del tubo digestivo y el peritoneo, pero a menudo es la inicialmente empleada ante cuadros inespecíficos. Aunque no exenta de limitaciones, presenta fortalezas que pueden permitirle aportar información diagnóstica significativa. Discutimos los datos ecográficos, clínicos y epidemiológicos más relevantes en la patología infecciosa, siguiendo un abordaje topográfico: estómago (Anisakis), intestino delgado proximal (Giardia lamblia, Strongyloides stercolaris, Complejo Mycobacterium-avium-intracelulare y Criptosporidium), intestino delgado distal (Yersinia, Salmonella, Campylobacter) íleon terminal y ciego (tuberculosis), colon derecho (Entamoeba histolytica), colon izquierdo (Shigella), recto-sigma, pancolitis (Clostridium difficile, Citomegalovirus, Escherichia coli) y peritoneo. Abordamos los hallazgos ecográficos y clínicos de la patología neoplásica más frecuente con un patrón nosológico: lesiones polipoideas como precursoras de neoplasias, carcinomas, tumores neuroendocrinos, hematológicos, mesenquimales y metástasis. Discutimos brevemente la patología tumoral del peritoneo y la ecografía como guía de biopsia percutánea.
