[A Case of Acute Afferent Loop Obstruction after Total Gastrectomy, Successfully Managed by Endoscopic Treatment].

The patient was a 76-year-old man who had 3 times previously undergone laparotomies, including distal gastrectomy with a Billroth Ⅰ operation. In the current case, a total gastrectomy, end-to-side esophagojejunostomy, and a Roux-en-Y anastomosis for adenocarcinoma of the remnant stomach were performed. On postoperative day (POD) 7, he complained of epigastralgia.

Successful closing of duodenal ulcer after endoscopic submucosal dissection with over-the-scope clip to prevent delayed perforation.

Closure of post-endoscopic submucosal dissection (ESD) duodenal artificial ulcer is not common in the clinical setting. We consider that post-ESD ulcer closure by an over-the-scope-clip (OTSC) method is one of the most effective ways to prevent delayed perforation. We report here two cases of mucosal duodenal cancer in a 65-year-old woman and in a 78-year-old man.

[Hemodynamic effects of anesthetic agents and bypass flow during orthotopic liver transplantation in pigs].

Although the hemodynamics during orthotopic liver transplantation is unstable, it is very important for new liver to get well-controlled hemodynamics. Thus hemodynamic changes were studied, especially in relation to the influence of anesthetic agents and bypass flow in orthotopic liver transplantation in pig. Hemodynamic changes associated with NLA, GOS (sevoflurane) and GOF anesthesia were evaluated.

[Estrogen and androgen receptors in hepatocellular carcinoma and in noncancerous liver tissue].

We have assayed both estrogen and androgen receptors in hepatocellular carcinomas, in the surrounding noncancerous liver tissue, and in normal liver tissue. Estrogen receptors (ERs) were detected in 5 out of 22 HCC tissues, 14 out of 22 surrounding noncancerous tissues, and in 5 out of 6 normal liver tissues. Androgen receptors (Ars) were detected in 4 out of 21 HCC tissues, in 7 out of 21 surrounding noncancerous tissues, and in 2 out of 5 normal liver tissues.
