Randomized Controlled Trial Clinical Trial
Perioperative prostaglandin E1 treatment for the prevention of postoperative complications after esophagectomy: a randomized clinical trial.
We conducted a prospective randomized clinical study to examine whether perioperative prostaglandin E1 (PGE1) could help in the prevention of postoperative complications after esophagectomy for esophageal cancer. ⋯ The perioperative administration of PGE1 helps maintain adequate portal blood flow, improves hyperbilirubinemia, and attenuates the duration of SIRS, thereby reducing the risk of postoperative complications after esophagectomy and lymphadenectomy for esophageal cancer.

Randomized Controlled Trial Clinical Trial
Jugular venous oxygen saturation during mild hypothermic versus normothermic cardiopulmonary bypass in elderly patients.
Age is known to be a major risk factor for adverse postoperative cognitive dysfunction after cardiac surgery. We conducted this study to determine if jugular venous oxygen saturation (SjvO(2)) differed during mild hypothermic (32 degrees C) and normothermic cardiopulmonary bypass (CPB) in elderly patients. ⋯ The SjvO(2) value was better during mild hypothermic CPB than during normothermic CPB in elderly patients.

Aortic dissection is characterized by fragility of the tunica media, and matrix metalloproteinases (MMPs) are enzymes that degrade the extracellular matrix of the aorta. This study examines MMPs in patients with acute aortic dissection (AAD) in an attempt to elucidate the mechanisms of their actions. ⋯ Low TIMP-2/MMP-2 and TIMP-2/MMP-9 ratios might play an important role in the onset of aortic dissection, when the tunica media becomes fragile with chronic breakage and degradation of the extracellular matrix.

Case Reports
Heparin-induced thrombocytopenia after coronary artery bypass grafting with cardiopulmonary bypass: report of a case.
A 79-year-old man was transferred to our hospital with severe chest pain and a suspected diagnosis of acute myocardial infarction. Emergency cardiac catheterization showed triple-vessel coronary artery disease, and we performed coronary artery bypass grafting under cardiopulmonary bypass (CPB). ⋯ We suspected heparin-induced thrombocytopenia (HIT), and immediately discontinued the heparin, implementing danaparoid (Orgaran) instead, following which the platelet count recovered. Heparin-induced thrombocytopenia, which causes thrombosis, is a serious side effect of heparin therapy and few cases of HIT associated with CPB surgery have been reported in Japan.

To investigate the results of wide rhomboid excision with Limberg transposition flap reconstruction to treat pilonidal sinus. ⋯ These results provide further evidence that wide excision with a Limberg transposition flap reconstruction is an effective surgical method for primary or recurrent pilonidal sinus, associated with a low complication rate, short hospitalization and disability, and a low recurrence rate. A modification of the technique was devised to further enhance wound healing and reduce the risk of recurrence.
