Sutureless end-to-end ileo-ileal intestinal anastomoses were successfully constructed with both the 1.06 jim neodymium:YAG and the 488/515-nm argon lasers. A 5-watt power setting was used with the neodymium:YAG, and various biologic solutions were added to the anastomotic seam during lasing. Power settings of 1.5, 3, 4, and 5 watts were used for argon lasing, with and without an exogenous chromophore. At the 4-watt argon setting, a continuous infusion of normal saline was dripped onto the anastomosis during lasing, replacing the chromophore. All bowel anastomoses were constructed with the aid of a biodegradable intraluminal stent that held the bowel ends in place during construction of the watertight ileal fusion and then completely degraded within 8 hours. We concluded that the neodymium:YAG seemed superior for tissue fusion using the techniques outlined, as it was associated with fewer anastomotic leaks. It appeared easier to determine the end-point of tissue fusion with the neodymium:YAG than the argon, because the tissue changes were more obvious during neodymium:YAG lasing. The deeper penetration into the bowel wall of neodymium:YAG laser energy may confer a welding advantage over the more shallow penetration of the argon wavelength.
