Abstract
Background: The gastrointestinal tract is the most common extranodal site involved by lymphoma. Endoscopic examination of gut lymphoma provides an excellent view of the mucosal surfaces of the whole gut. Transabdominal ultrasonography (TUS) can demonstrate the layers of the bowel wall and is useful for guiding biopsies. Aim of the work:The aim of this study was to correlate the abdominal ultrasonographic and endoscopic features of gastrointestinal (GI) lymphoma, and to assess whether TUS has a complementary role to endoscopy in the diagnosis of gastrointestinal lymphoma. Patients and Methods: This study was conducted on patients with GI lymphoma from May 2014 to July 2015, (primarily diagnosed as having gastrointestinal lymphoma), attending the Gastrointestinal endoscopy unit, Endemic Medicine Department and Oncology Department in Kasr El Aini hospital, Cairo university. Patients were subjected to GI endoscopy (Upper endoscopy & Colonoscopy) and transabdominal ultrasonography. The diagnosis was finally based on histopatholoy of core biopsies (obtained either endoscopically or by ultrasonography) and immuno-histochemistry.
