New techniques of gastrointestinal anastomoses using the EEA stapler.

A new instrument for performing end-to-end, inverted stapled anastomoses in the gastrointestinal tract is described. Its advantages and disadvantages are also discussed. Techniques to avoid a proximal enterotomy or colotomy are described in Billroth I gastrectomy and end-to-side ileocolostomy, and experience with 30 anastomoses, their hazards, and complications are reported. The instrument creates a better anastomosis and shortens the operative time.
