Background: Revision of gastric bariatric operations
is sometimes technically difficult and may fail to
achieve prolonged weight reduction. The use of the
adjustable silicone gastric banding (ASGB) offers a
new approach for these revisions.
Methods: ASGB was performed as a revisional
procedure on 37 patients whose initial bariatric oper-
ations were as follows: silastic ring vertical gastro-
plasty (21), gastric bypass (12), horizontal gastro-
plasty (3) and vertical banded gastroplasty (1).
Results: The length of the procedure varied from
55 to 145 minutes (mean 83 minutes). Intraoperative
complications included two fundic tears which were
sutured without any postoperative sequelae. Five
patients needed reoperation during the first postop-
erative year due to gastric volvulus (1), tubing tear
(1) and development of postoperative ventral hernia
(3). BMI fell from 44.8 ± SD 8.07 to 33.4 ± 6.9 kg/m

for
patients operated with BMI higher than 35 kg/m

and
from 29.2 ± 3.32 to 25.4 ± 2.8 kg/m

for patients oper-
ated with BMI lower than 35 kg/m

.
Conclusions: ASBG can be performed with revi-
sions with an acceptable complication rate and post-
operative weight reduction.

Introduction
Regain of body weight after initial satisfactory
weight reduction may occur after gastric bartiatric
operations. There may be many clinical reasons
responsible for this occurrence, such as staple-line
disruption or pouch dilatation after silastic ring
vertical gastroplasty (SRVG) or stoma and/or
pouch dilatation after gastric bypass (GBP).
Correction of these conditions is sometimes tech-
nically difficult and may fail to achieve prolonged
weight reduction. The introduction of the
adjustable silicone gastric band (ASGB) offers a
new more feasible operative approach. An advan-
tage of this technique is that it is associated with
minimal additional trauma to the stomach because
no suture-lines or anastomoses are needed. In addi-
tion, postoperatively a desired stomal size can be
achieved. We hereby describe retrospectively our
experience with the use of ASGB (Lap-Band

after failure of earlier gastric reduction procedures.
Patients and Methods
From January 1996 to May 1998, introduction of
an ASBG was performed on 37 patients, who had
undergone an earlier gastric bariatric procedure
which failed. Their ages were 17 - 65 years (mean
38 years). The previous procedures were SRVG –
21 patients, GBP – 12 patients, horizontal gastro-
plasty – 3 and vertical banded gastroplasty (VBG)
– 1 patient. In three patients, the present procedure
was the third bariatric gastric operation. The time
elapsed since the initial bariatric operation varied
from 2 - 192 months (mean 94 months).
Failure of the initial procedure was evident by
increased body weight after satisfactory weight
reduction in 34 of the patients. The causes for this
