Abstract: | Sutureless end-to-end intestinal anastomoses were constructed in New Zealand white rabbits using an argon laser to weld the tissue edges, which were temporarily held together by a biodegradable, water-soluble, intraluminal stent. Various power settings ranging from 1.5 to 5 W were used with and without an exogenous chromophore (India ink). Delivering 4 W of power without using an exogenous chromophore but applying a continuous saline drip to the anastomotic seam during lasing proved most successful. We conclude that argon laser energy can be used to construct successful sutureless end-to-end intestinal anastomoses. |
