title: Endoscopic ultrasonography: Challenges and opportunities in the developing world.
abstract: Endoscopic ultrasonography (EUS) has become a vital diagnostic modality for the evaluation of mediastinal lymphadenopathy, pancreatic cysts and masses, anorectal pathology, subepithelial gastrointestinal lesions, and for the staging of many gastrointestinal and pulmonary malignancies. Establishing a EUS program in a developing country presents many challenges. Doing so in Pakistan has led to the identification of the following challenges: initial investment, ongoing costs (particularly fine needle aspiration needle costs), awareness and cytopathology. Endoscopic ultrasonography has revolutionized aspects of the practice of gastroenterology and oncology in the West. This technique is becoming increasingly available in the developing world, where it poses unique challenges to its practice. These challenges include those relating to service initiation and maintenance costs, physician awareness, and on-site cytopathology access. If these issues are anticipated and addressed in ways appropriate to local circumstances, obstacles to the institution of EUS programs can be overcome.
