there is an inherent      risk of spillage of gastric juices, bile, or
                                                                                                     the crossbar will realign itself along the axis of the sheath lumen and

tion [4] of the visceral wall during tract dilatation     or malinser-
tion of drains due to intraperitoneal coiling of guide wires [5],
safer methods    have been devised, including percutaneous
endoscopic    gastrostomy    [1 ], the Hawkins    accordion     system
[6], and air or balloon distension     of the stomach     [7]. None of
these techniques,                 however,      prevents      harmful    leakage      during
early drain exchanges  or intravisceral    catheter manipulations.
A new simple removable     retention    device is described    which
serves to firmly anchor the visceral wall against the parietal
wall for safer drain insertion.

Materials         and     Methods

    The device consists of a stainless-steel  cannula or rod 6-1 0 mm
long that is jacketed in a plastic or helical spring sheath (OD, 0.87
mm) and fitted with a center and an end suture. The part of the
suture that arises from the center of the anchoring device is armed
with a curved cutting needle. The purpose of the sheath is to provide
atraumatic floppy ends to the stiff crossbar (fig. 1).
    A 15-cm, 22-gauge fine needle over which is telescoped a 5-cm,
1 6-gauge plastic-sheathed   needle is used for puncture. Once the
distended viscus lumen is localized with the protruding fine needle,
the sheathed needle is advanced over it, and the sheath left in place.
The anchor device is aligned with the end suture trailing and pushed
through the plastic sheath with a 0.038-inch (0.96-mm) J guide wire
into the cavity         of the hollow       viscus   (fig. 2A). When     the center   suture
is pulled back with the sheath, the retention bar will align itself
perpendicularly  to the needle tract. On further traction the crossbar
will engage the visceral wall and eventually bring it into close approx-
imation to the body wall(fig. 2B). With the visceral wall firmly retracted
against the panetal wall, there is little chance of intraperitoneal
    The tension of the center thread is maintained by suturing it to the
skin, thus preventing              retraction   of the viscus.     The wire guide,        which
had previously been inserted into the cavity, can now be used to
further dilate the tract and insert a drain with impunity (fig. 2C). The
loose end suture is taped to the drain. A few days later, when the                                      Fig. 1 -Floppy-tip     spring-sheathed   suture anchor. Center   suture    with
