We have performed totally laparoscopic stomach-partitioning gastrojejunostomy for gastroduodenal outlet obstruction caused by advanced malignancies in 14 cases. We divided 14 patients into 2 groups according to age at surgery: those<80 years of age and thoseB80 years of age. We compared these 2 groups regarding preoperative status, operative findings, and postoperative course.

Unexpected Radiologic Findings for a Casting Type of Radiolucent Colorectal Foreign Body Composed of Polyurethane Foam.

Radiologic diagnosis of colorectal foreign bodies is usually not very difficult, because inserted materials are often clearly visible on plain abdominal radiographs. However, when they are radiolucent, a plain abdominal radiograph has been reported to be useless. As radiolucent colorectal foreign bodies appear as radiolucent artificial contours or air-trapped materials in the pelvis, almost always the diagnosis itself can be made by careful evaluation of plain abdominal radiographs.
