Abscess formation of the round ligament of the liver is very rare. We report a case of a 70-year-old female with abscess of the round ligament after an endoscopic papillotomy for choledocholithiasis. On the 21st day following papillotomy, abscess formation of the round ligament was found by ultrasonographic examination. Surgical treatment was performed because conservative therapy was not effective. The purulent fluid and necrotic tissue at the round ligament were completely removed. Cultures obtained from the abscess grew Staphylococcus epidermidis, but the mechanism of abscess formation in this case remains unclear.

An unusual case is described in which an abdominal wall and thigh abscess was an initial symptom of ascending colon cancer. A 76-year-old woman was referred to our hospital for investigation of fever and abdominal and thigh swelling. Computed tomography revealed a right abdominal wall, retroperitoneal, psoas and thigh abscess formation suspected to be caused by colon perforation. Due to the patient's poor general condition, local drainage of the abscess was performed on the following day of hospitalization. Histological examination of necrotic tissues removed form the retroperitoneal cavity demonstrated adenocarcinoma of the colon. The patient subsequently underwent right hemicolectomy with lymph nodal dissection after 19 days of the drainage procedure and was transferred to another hospital on the 49th day following the second surgery.

A centrifugal pump was successfully used as a left ventricular assist device (LVAD) in a 54-year-old female who developed cardiogenic shock following open heart surgery. Cardiac index prior to the LVAD support was 1.4 l/min/m2 and increased to 3.0 l/min/m2 at removal of the device, which assisted for 88h. She resumed her daily activity 10 months after the operation and is in New York Heart Association functional class I.

The direct determination by gas chromatography of blood levels of anesthetic agents has been difficult because of the water content of blood. In the present study, the method of Yokota et al. (1967) was modified by improving the packing materials of the column, the blood sample vaporizer and the flow-path during analysis. As a result, accurate and reproducible determination of halothane, enflurane and isoflurane dissolved in blood was achieved. With this system, blood in which halothane, enflurane and isoflurane had been dissolved could be analyzed without changing the column between samples. Moreover, each sample was prepared in less than 10 min, and more than 100 consecutive determinations could be made with excellent reproducibility. The coefficient of variation was less than 3.8%.
