New "sutureless" technique of ileostomy and colostomy.
BACKGROUND
Brooke ileostomy and colostomy are associated with infection in the stomal and/or main wounds, leading to complications. The source of infection is feces from the open lumen. The objective of the present study was to find a way to prevent infection and subsequent complications. It was started in 1986 by serendipity after discovery that if wound contamination from intestinal contents is stopped in the immediate postoperative period, by a complete small/large intestinal obstruction, infection and complications are prevented. This study was based on the principle of delayed-primary wound closure.


METHODS
Following its initial discovery for a Brooke ileostomy, the procedure was used for both ileostomy and colostomy. The stapled stoma was fixed to the opening in rectus sheath. It was covered with an appliance that has a transparent pouch, allowing daily inspection. During the period of postoperative ileus, there is angiogenesis on the serosal surface, making it refractory to infection. The stoma tends to bulge with the appearance of peristalsis. Stoma was then opened with electrocautery in a bedside procedure. The mucosal cuff protrudes, everts, advances with peristalsis, and "grafts" itself on angiogenesis on the surface of a single layer of serosa. The advancing margin of the mucosal cuff fuses with the circumference of the opening in dermis. The maturation of the stoma is natural and automatic. Absence of sutures reduced the tissue trauma and foreign body reaction, resulting in better wound healing. This new procedure was named "delayed-primary self-maturation" (DPSM).


RESULTS
Thirty seven colostomies and nine ileostomies were performed using DPSM. Infection in the stomal and/or main wound and subsequent complications were prevented.


CONCLUSIONS
Delayed-primary self-maturation is technically easier and more scientific than a conventional ileostomy or colostomy and is recommended for all types of stomas.
