ts with superficial colorectal neoplasms in their study and randomly assigned them to undergo ESD using either the flushknife or the flexknife (an electrosurgical endo-knife without a water-jet function). They found that the flushknife enabled them to rinse mucus and blood clots and to inject saline into the submucosa during the procedure, which is an important step in avoiding perforation of the colon during ESD.

"The flushknife is clearly a superior tool to use in performing ESD," said Dr. Takeuchi. "However ESD continues to be a very difficult procedure that not every endoscopist can perform. Further developments are needed for colorectal ESD to become the standard procedure for large colorectal tumor removal."

Dr. Takeuchi will present these data on Tuesday, May 3 at 10:54 a.m. CT in 280-282, Ernest N. Morial Convention Center.

Development of an Artificial Gastric Wall Using Bioabsorbable Polymer (Abstract #439o)

Researchers from Saitama Medical University in Saitama, Japan, have developed a ground-breaking material that can repair and regenerate the gastric wall without deforming the stomach or disrupting GI function. The material, an implanted bioabsorbable polymer (BAP) patch, has been shown to preserve normal GI function after GI surgery in animal models.

Currently available surgeries to remove abnormal tissue growth in the stomach are highly effective, but involve partially removing portion(s) of the stomach, leaving the stomach deformed and/or with decreased GI function. Investigators developed an implantable BAP patch to serve as an artificial gastric wall to allow removal of defective stomach tissue without impairing function or biology of the organ. The BAP patch is composed of a 50:50 copolymer of polylactic acid and polycaprolactone reinforced with polyglycolic acid fibers and designed to degrade about six to eight weeks after implantation. Investigators evaluated the technique in 15 hybrid pigs. <
