LA CONVERSIONE DA BAND A BY PASS
"single step"
Restrictive Procedures: long-term break down up to 40%
 Poor quality of life
 Psychological intolerance, frequent vomiting, GERD
 Failure
 Insufficient weight loss
 Weight regain
 Long term complications
 Gastric pouch dilatation/slippage
 Intragastric band migration

 33 patients with pouch dilatation after GB (6,7 %)
 16 repositioning / re-banding
 9 band removal
 8 conversions to RYGBP
 Patients often gain weight (10 / 16) and are dissatisfied after rebanding
 All patients converted to RYGBP lost further weight and were
extremely satisfied (better food tolerance, no vomiting)

How to approach revisional surgery :
 Actual and maximal weight loss after first procedure
and initial weight before the first procedure
 Type of complication if present: barium swallow, EGDS
 Quality of life:
o Psychological tolerance
o Digestive tolerance :
 Alimentary comfort
 Frequency of nausea and vomiting
 Gastro - oesophagal reflux
 Surgical team skill
 Patients wish

GENERAL PRINCIPLES



Get the old operative report
Be sure that patients are aware of increased
risks and lower likelihood of success.
Obtain Upper GI contrast study to determine
staple line integrity and location of GE
Junction.

Conclusion

All restrictive procedure are theoretically associated with long
term failure and/or mechanical complications

A lifelong multidisciplinary management and surveillance for these
patients appears compulsory

Bariatric revisional surgery is a major concern

RYGBP is a very good rescue procedure after failure of restrictive
procedure

Conclusion
The laparoscopic conversion of failed gastric bands to
Gastric Bypass in “one step” is reported in literature to
be safe in high volume centres.
In our experience excellent results in term of:
 Morbidity and mortality: 0%
 Weight loss :EWL%>70
