    Notes: Abstract Background Percutaneous gastrostomy in patients with a partial gastrectomy is rarely performed because the gastric remnants are generally small, positioned high subcostally, and overlaid by the transverse colon and the left lobe of the liver. Methods We performed percutaneous transhepatic feeding gastrostomy in four patients with a partial gastrectomy whose conditions precluded oral feeding. The gastric remnant was punctured with a 22-gauge percutaneous transhepatic cholangiography needle through the left lobe of the liver with computed tomography guidance and following tract dilation over the guidewire 8 or 9F. Cope loop catheters were fluoroscopically placed. Results No obvious complications were encountered during the procedures. The catheter feedings were continued for 2 to 7 months without any serious problems. Conclusions We conclude this technique can be performed easily and may be safe because of the presence of the adhesion between the remnant and the liver, which prevents a massive hemorrhage or the displacement of the catheters.

    Notes: Summary The ability of RPMI4788 cells, a human colon cancer cell line, to produce experimental metastases in the lung, intraperitoneal cavity, and liver was studied in nude mice. Injection of 2×106 tumor cells into the tail vein of nude mice produced metastatic lung tumors, and an intraportal injection of 5×106 cells produced metastatic liver tumors. An intraabdominal carcinomatosis with ascites was formed after an i.p. injection of 5×106 tumor cells. The nude mice with lung metastasis or intraabdominal carcinomatosis always died within a few weeks. Macroscopic observation showed that the number of lung metastatic nodules on day 21 after tumor inoculation was 311.3±78.2 (mean±SD) in BALB/C nude mice, and 187.5±26.7 in ICR nude mice. In survival experiments, the mice with intraabdominal carcinomatosis showed a mean survival of 29.0±1.7 (mean±SD) days in BALB/C nude mice and 43.6±6.1 days in ICR nude mice. These novel experimental models of metastases in nude mice produced by injection of RPMI4788 cells had high reproducibility and may be useful not only for the study of the metastatic process but also for testing anticancer drugs.
