IntroductionLook at 29 patients who have had either a failed
Gastric Band – adjustable and fixed , VBG/HGR or Jejuno-ileal bypass
Failure was either weight regain/non weight lossTechnical failure of the original operationOther issues – gastroparesis, reflux and vomiting
Techniques for revision
Results of our experience

Sometimes surgery doesn't work

Revision is an option2 surgeon series
29 cases of conversion of HGR/VBG, Gastric Band or jejuno-ileal bypass to RYGB
Experienced in RYGB – open and Laparoscopic

Gastric Band FailureDefined as either no weight loss at all or
weight loss of less than 10% EW
Variety of reasonsMaladaptive eating behaviorTechnical issues with the band Recurrent slipDilation of the pouch

Failure of VBG/HGRLate failures - most 10years +
Maladaptive eating behaviour
Dilatation of the pouch – weight regain or reflux
Staple line dehiscence – weight regain

Reversal of staplingEncouraged to reverse if severe maladaptive
eatingReversal is by removal of the sutures6 months of normal diet and exercise prior to
reversal

Methods of revisionAll patients are fully evaluated by a
multidisciplinary teamOften have seen a Nutritional physicianGastroscopyBarium series At least 2 pre operative consults with the
surgeon2 weeks of optifast BMI <504 weeks of optifast BMI>50

Results 29 patientsRange of previous surgeriesOften multiple operations - open and
laparoscopicMostly failure of weight lossSignificant amount of failures related to
technical issuesAll successful completion to RYGB3 underwent a partial gastric resection2 underwent a partial liver resection

ResultsLimited by follow up of 2-18 monthsAverage weight – 121 kg170kg – 80 kg20 females and 9 malesWeight loss average – 60% EW excluding patients
<6months
All had resolution of gastroparesis
Significant improvement in diabetes
All had resolution of reflux and vomiting

ComplicationsLeak – 2 gastrojejunostomy leaks
Bile leak – 1 bile leak treated by percutaneous drain
Wound infection – 2 wound infections requiring AB and 1 requiring VAC dressing
Incisional hernia and internal herniation – 5 incisional hernias and 1 internal hernia
![Page 19: Revision of failed restriction to RYGB](https://reader036.vdocument.in/reader036/viewer/2022081507/56816624550346895dd97f0a/html5/thumbnails/19.jpg)
LOS and return to workAverage LOS – 5 days
Return to work – 3.5 weeks
TAKES AT LEAST 3 MONTHS TO RETURN TO PREOPERATIVE QUALITY OF LIFE

Tips and pitfalls - staplingImportant to determine if stapling is dehisced
or if large pouchIf large pouch – must stay within the staple
line – risk of ischaemiaSometimes better to perform a fundectomy
excising the fundus and staple line – easier to enter the lesser sac away from adhesions
Fundectomy/mini sleeve can minimize splenic injury

Gastric bandIf there is slippage – REMOVE THE BAND AND
WAIT
If no slippage it is safe to perform in one surgery – MUST REMOVE THE CAPSULE AND ALL SUTURES
GREEN LOADS +/- SEAMGUARD

Difficult Left lobe of LiverBleeding
Adhesions
Can remove part of the left lobe safely with the echilon stapler
Less bleedingLess Bile leak

Post operative NGT – 24 hoursGastrograffin swallow 24-48 hrsFluids after confirmation of no leakJackson pratt drain for 5 days
In very large patients useful to drain the subcutaneous space
Vac dressings can be useful in very large patients with wound infection
