Case of cecal volvulus successfully treated with endoscopic colopexy.

We herein report a case of cecal volvulus successfully treated with endoscopic colopexy. A 73-year-old man with a high fever and abdominal fullness was diagnosed with ileus caused by cecal volvulus. CT showed a dilated cecum and small intestine without bowel strangulation as well as acute pneumonia.

Efficacy of the projection onto convex sets (POCS) algorithm at Gd-EOB-DTPA-enhanced hepatobiliary-phase hepatic MRI.

Purpose: To investigate the efficacy of the projection onto convex sets (POCS) algorithm at Gd-EOB-DTPA-enhanced hepatobiliary-phase MRI.

Methods: In phantom study, we scanned a phantom and obtained images by conventional means (P1 images), by partial-Fourier image reconstruction (PF, P2 images) and by PF with the POCS algorithm (P3 images). Then we acquired and compared subtraction images (P2-P1 images and P3-P1 images).

Acute gastric volvulus in a patient with trisomy 21.

Acute gastric volvulus is a torsion of the stomach by more than 180° and a life-threatening condition. We present a 50-year-old male patient with acute abdominal pain who has Down syndrome/trisomy 21. Computed tomography showed a significant distended stomach with features of a severe gastric volvulus.

Contrast enhancement during hepatic computed tomography: effect of total body weight, height, body mass index, blood volume, lean body weight, and body surface area.

Objective: The objective of this study was to evaluate the effect of total body weight, height, body mass index, blood volume, lean body weight, and body surface area (BSA) on aortic and hepatic contrast enhancement during hepatic computed tomography (CT).

Methods: We calculated the changes in the CT number per gram of iodine ((Δ Hounsfield units/g [ΔHU/g])) for the aorta and the liver during portal venous phase. We performed linear regression analyses between ΔHU/g and each of the body parameters.

Successful conservative treatment of pneumatosis intestinalis associated with intraperitoneal free air: report of a case.

While pneumatosis intestinalis (PI) is a rare condition associated with a wide variety of underlying diseases, PI with intraperitoneal free air and ascites is extremely uncommon and is difficult to distinguish from diffuse peritonitis. We herein describe the case of an 87-year-old male who was admitted to our hospital with abdominal pain, distension and nausea. Abdominal plain radiography and computed tomography revealed intramural air collection in the entire intestine, intraperitoneal free air and ascites.

Resectable gallbladder cancer presenting with acute pancreatitis caused by hemobilia.

A 79-year-old female was transferred to our hospital because of suspicion that her acute pancreatitis was caused by stone impaction in the common bile duct (CBD). Laboratory examination showed aspartate aminotransferase, 1645 U/l; alanine aminotransferase, 476 U/l; amylase, 1365 U/l; and white blood cells, 10700/μl. Computed tomography (CT) showed an enhanced tumor in the neck of the gallbladder, an abnormal CBD filled with a high-density area, and localized swelling in the head of the pancreas.

Abdominal dynamic CT in patients with renal dysfunction: contrast agent dose reduction with low tube voltage and high tube current-time product settings at 256-detector row CT.

Purpose: To evaluate the feasibility of a low-contrast agent dose protocol at abdominal dynamic computed tomography (CT) with a low tube voltage high tube current-time product technique and a 256-detector row CT unit.

Materials And Methods: This prospective study received institutional review board approval; written informed consent to participate was obtained from all patients. The study included 151 patients; 117 had an estimated glomerular filtration rate (eGFR) greater than or equal to 60 mL/min/1.
