Experimental ileal J-pouch construction

Abstract

Endorectal ileal pouch-anal anastomosis has become the surgical alternative of choice for patients requiring colectomy for ulcerative colitis or familial polyposis coli. The optimal method of ileal pouch construction has not been determined. In this study, a canine preparation was used to compare the immediate results of three different techniques of ileal J-pouch construction. The three methods studied were two-layer hand-suturing (HS), stapling through enterotomies placed laterally on the ileal limbs (LS), and stapling via an apically placed enterotomy (AS). All three techniques resulted in watertight reservoirs. Ease of construction was scored significantly differently among the pouch variations (AS > LS > HS). Construction times was significantly less for both of the stapled reservoirs than for the HS pouch. Capacity of the AS pouch was significantly greater than the HS reservoir. This study suggests that stapling the ileal J-pouch through a single apical enterotomy should be the preferred technique during colectomy, mucosal proctectomy, and ileal pouch-anal anastomosis.
