Pancreatic enzymes in the ischemic intestine are involved in the production of in vivo inflammatory mediators. These mediators stimulate cells in the cardiovascular system during shock and initiate multiorgan failure. An important aspect that controls the extent of the inflammation is the dispersion of these mediators from the ischemic intestine. In the(More)
OBJECTIVE Interruption of incompetent perforating veins (PVs) is important for varicose vein surgery. The purpose of this study was to evaluate the preoperative and intraoperative diameter-reflux relationship of PVs and to evaluate the accuracy of preoperative duplex scanning in patients with varicose vein. METHODS Patients with primary varicose veins(More)
To evaluate the efficiency of the form PWV/ABI (pulse wave velocity/ankle brachial pressure index) for measuring penile blood pressure (PBP) and the penile brachial pressure index (PBI). We measured PBP and the PBI using both form PWV/ABI and Doppler ultrasonography in 40 men with surgical disorders. By using pulse-volume recording, the form PWV/ABI can(More)
Purpose. This study reviews 51 consecutive patients with superficial thrombophlebitis (STP) among 710 patients treated for varicose veins in our department. Methods. An assessment was made of various factors involved. Results. Of these 51 patients, 21 (41.1%) had systemic disorders, including 4 (7.8%) with malignant diseases. Six patients (11.8%) had deep(More)
BACKGROUND Plasma platelet-activating factor-acetylhydrolase (PAF-AH) is known to catalyze platelet-activating factor (PAF). The single nucleotide polymorphism (SNP) of plasma PAF-AH gene (G994 -->T in exon 9) is associated with a decreased level of plasma PAF-AH activity. This study analyzed the risk of the SNP on graft occlusion of femoropopliteal bypass(More)
OBJECTIVE We investigated the relation between flow pattern in abdominal aortic aneurysm (AAA) and intravascular coagulopathy characterized by increased fibrin degradation product d-dimer (FDP-DD) or thrombin-antithrombin complex (TAT). Materials and methods The ratio of AAA maximum endoluminal diameter (diameter of flow channel) (n = 23) to diameter of the(More)
Since general thoracic surgery requires a short fasting period, the number of cases that require nutrition support after surgery is limited and few reports exist about nutrition in general thoracic surgery and chronic empyema. Here we report 2 cases of chronic empyema treated with nutritional support team (NST) followed by omentopexy. For chronic empyema, a(More)
Percutaneous transhepatic gallbladder drainage (PTGBD) is an alternative to emergency laparoscopic cholecystectomy in high-risk patients with acute cholecystitis. Severe complications of this procedure are rare, except for drainage tube-related complications. A case of thoracic empyema, which is a rare complication of PTGBD, is reported; penetration of the(More)
Elderly patients usually have concurrent ailments, and the safety and effectiveness of laparoscopy-assisted distal gastrectomy (LADG) for these patients have been controversial. This study aimed to evaluate whether laparoscopy-assisted distal gastrectomy is safe and effective for elderly patients aged 80 years and over, as well as to clarify their long-term(More)
A 65-year-old woman was admitted with sudden-onset abdominal pain. Abdominal computed tomography revealed hepatic portal venous gas. Physical and laboratory examination suggested that a conservative approach was appropriate; however, 4 days later, the pain recurred and severe ischemic enteritis was diagnosed. A stenosis was identified 60 cm distal to the(More)
