Aa. Chahine et Rr. Ricketts, A MODIFICATION OF THE BIANCHI INTESTINAL LENGTHENING PROCEDURE WITH ASINGLE ANASTOMOSIS, Journal of pediatric surgery, 33(8), 1998, pp. 1292-1293
Background/Purpose: Intestinal lengthening, as described by Bianchi, i
s the most commonly used method of gastrointestinal reconstruction for
the therapy of short bowel syndrome. It divides the bowel in two long
itudinal halves based on the bifurcated mesenteric blood supply, then
reconnects the two halves in series with the rest of the small intesti
ne. This requires three end-to-end narrow anastomoses in addition to t
he two longitudinal sutures lines. The authors describe a modification
of the Bianchi procedure that lengthens the small intestine with a si
ngle wide end-to-end anastomosis thus avoiding two suture lines and th
eir potential complications. Methods: The anatomic principle used in t
his modification is the same as that described by Bianchi. The mesente
ry is separated based on the bifurcated vessels. With sequential firin
gs of the stapler, the division of the intestine begins obliquely, pro
ceeds longitudinally as in the Bianchi procedure, then ends obliquely
at the other end of the intestine. This results in two divided segment
s that remain attached to the proximal and distal intestine and end in
tapered staple lines. The two ends are sewn into a wide tapered anast
omosis, reestablishing intestinal continuity with a single anastomosis
instead of three. Conclusions: This simple modification, which we hav
e used on two patients so far, decreases the number of anastomoses in
an intestinal lengthening procedure from three narrow ones to one that
is wider and tapered, thus reducing the risk of leaks and strictures.
Because the end result is a lengthened intestinal segment similar to
the Bianchi procedure, it should be equally effective in the therapy o
f short bowel syndrome. Copyright (C) 1998 by W.B. Saunders Company.
