A new irrigating proctoscope was invented to minimize implantation metastases by reducing exfoliated cororectal cancer cells in the distal rectum during anterior resection for rectal cancer. The proctoscope was used in 12 cases of rectal cancer following the clamping of the distal rectum prior to rectal dissection. Irrigation was performed with 2000 ml of saline after insertion of the proctoscope through the anus. Exfoliated cancer cells in the irrigation fluid were examined cytologically after every 500 ml of irrigation. Exfoliated cancer cells were demonstrated in the first sample of irrigation fluid in all cases, but few cancer cells were demonstrated at the end. The Irrigation time was 5 minutes and 29 seconds. More than 1000 ml of saline was considered to be needed to eliminate the exfoliated cancer cells for rectal cancer below the peritoneal reflection, and more than 2000 ml of saline for cancer above the peritoneal reflection. The new irrigating proctoscope was considered to be helpful in completing rapid, and effective irrigation without operating theater pollution.
