Among the techniques for dealing with common bile stones, choledochodu
odenostomy (CDS) represents a useful alternative. This operation is in
dicated mainly in patients,vith recurrent stones, giant stones, or con
comitant common bile stricture and duct stones. At the present time mo
st of the patients undergoing CDS have been already undergone endoscop
ic retrograde cholangiography or ultrasonography to study the common b
ile duct and the cause of symptoms. The common bile duct diameter is o
f paramount importance when determining the feasibility of performing
a CDS, the critical size being 1.2 cm. The most common operation is a
side-to-side anastomosis employing absorbable sutures. Stomal patency
is the most important factor for preventing classic complications such
as cholangitis and sump syndrome. These complications are rare, being
observed in only 5% of the patients. Long-term results of the operati
on show that it is a safe procedure that should be considered a good o
ption in selected patients with choledocholithiasis.
