Diagnostic utility of immunochemical fecal occult blood tests to detect lower gastrointestinal lesions in patients with chronic kidney disease.

Purpose: The immunochemical fecal occult blood test (iFOBT) is a useful method to screen for lower gastrointestinal (GI) bleeding-related lesions. However, few studies have investigated the diagnostic utility of iFOBT in chronic kidney disease (CKD).

Methods: We included 691 patients with nondialysis-dependent CKD stages 2-5 or those receiving dialysis.

Use of blood tests to predict upper gastrointestinal lesions in patients with chronic kidney disease.

Objective: Anemia and iron deficiency are common complications in patients with chronic kidney disease (CKD). However, information about the diagnostic indicators of bleeding-related upper gastrointestinal (GI) tract lesions is sparse and few studies have investigated anemic upper GI tract lesions.

Methods: We included 165 anemic patients with non-dialysis-dependent CKD stages 3 to 5 (44 patients at stage 3, 52 patients at stage 4, and 69 patients at stage 5).

[Midgut volvulus in a 70-year-old man due to intestinal nonrotation].

Intestinal malrotation is a congenital disorder that results from the failure of normal bowel rotation and fixation during the 5th gestational week. The incidence of intestinal malrotation is <0.2%, but prompt diagnosis is important because this anomaly can cause midgut volvulus and lead to fatalities.

Decisive indicator for gastrointestinal workup in anemic patients with nondialysis chronic kidney disease.

Background: Anemia and iron deficiency are universal problems in patients with chronic kidney disease (CKD). However, decisive indicator to guide the further gastrointestinal (GI) workup has not been determined.

Methods: We included 104 anemic patients with nondialysis-dependent CKD stages 3-5 (38 patients at stage 3, 26 patients at stage 4, and 40 patients at stage 5).
