Purpose: To assess the value and feasibility of computed tomographic gastrography and multiplanar reformatting in the preoperative evaluation of patients undergoing laparoscopic gastric resection.
Materials And Methods: Fourteen patients with gastric lesions were included in the study. A supine scan was performed after a hypotonic drug, an effervescent agent, and intravenous contrast.

Background: A 65-year-old white Mediterranean male with a 10-year history of intermittent anemia, who was otherwise completely asymptomatic, was referred to our hospital in March 2004. He had a medical history of beta thalassemia and fecal occult blood tests had occasionally been positive.
Investigations: Fecal occult blood test, laboratory investigations, esophagogastroduodenoscopy, colonoscopy with retrograde ileoscopy, mesenteric angiography, small-bowel series, CT scan of the abdomen and pelvis, Meckel's scan, and capsule endoscopy.
Background: Postoperative recurrence of Crohn disease is a common problem. It has been assumed that the radiologic patterns are similar in de novo and recurrent ileal disease, but there has been little in the literature to actually confirm this belief.
Methods: We retrospectively reviewed the small bowel examinations of 105 consecutive patients with a proven diagnosis of Crohn disease: a control group of 47 patients with no prior surgery and a postoperative group of 58 patients with resections.
Background: Little is known about the accuracy of capsule endoscopy (CE) in evaluation of small-bowel Crohn's disease.
Methods: Symptomatic eligible patients had ileocolonoscopy and biopsies from the terminal ileum, followed by small-bowel radiologic studies before CE. Endoscopic, radiologic, CE, and histologic findings were compared.
