banded gastric bypass
History of the Banded Gastric Bypass
However, RYGB is also related to specific complications and long-term weight regain.
Over the years several modifications have been suggested to the RYGB of which the banded gastric bypass seems to be the most effective, with superior weight loss results and similar or even improved complication rates.
Many bariatric surgery techniques have come and gone since then, but the banded bypass has steadily built up an experience base demonstrating its superior outcomes in terms of safety and effectiveness.
It is one of the few bariatric surgical techniques which can show more than 10 year follow up data and various randomized controlled trials are in process today.
Weight Regain after Gastric Bypass
This is the basic principle of banding the bypass: protecting the stoma against overstretching, slowing down the passage of food and providing restriction to the patient when overeating.
Banding the pouch has a positive effect in the prevention of weight regain.
Lemmens (9) also described in his series of 432 patients with a minimum follow up of 5 years that more than 45% of the BRYGB patients did not experience any weight loss at all vs. only 27% in the RYGB group. Of those patients who did gain weight at some point after their operation, the BRYGB patient invariably showed less regain than the RYGB patients (see fig. 1).
Primary Banded Gastric Bypass
Doing it right the first time!
“ Banded gastric bypass is an attractive bariatric procedure with superior weight loss outcomes, best demonstrated in super-obese patients. ”
“ The current meta-analysis and trend line comparisons suggest that B-RYGB’s intermediate term weight loss outcomes may be superior to those of RYGB.”
More recently Galal stated in his single center retrospective analysis of 142 patients that banded gastric bypass has good results in terms of weight loss and weight loss maintenance in both primary and conversional bariatric procedures with acceptable incidence of band-related complications.
Whereas RYGB and bariatric surgery patients, on the whole, reach their BMI nadir approximately 2 years post-surgery and find that their weight loss decreases, this pattern was not seen in the current analysis of B-RYGB.”
Banded Gastric Bypass Superobese Patients
Schauer (4) demonstrated in 2014 in a randomized controlled trial, that banded gastric bypass is especially beneficial for the superobese patients: 20% more EWL within 2 years for the banded patients compared to the standard RYGB group.
Banded Gastric Bypass and prevention of Dumping Syndrome
Linke (11) displayed limited extra weight loss but did show the positive effect the Banded Bypass has on Dumping Syndrome after revisional surgery with the MiniMIZER Gastric Ring.
Dr. Buchwald in his meta-analysis stated a significant proportion of RYGB patients experience dumping syndrome, whereas no instances of the syndrome were reported in B-RYGB patients in the included studies.
Banded Gastric Bypass as a Revision Procedure
Boerboom (10) showed in 2019 that in 75% of patients with weight regain after RYGB, further weight regain was prevented and 26% of patients started to lose weight again.
A significant outcome of this study was the difference in results for Good – and Poor responders.
Patients that have not achieved an EWL% of 50 or higher after a Bariatric Procedure are Poor responders, whereas those that have achieved an EWL% of 50 or higher are classified as Good responders.
Adding a MiniMIZER Gastric Ring to a Gastric Bypass will result in renewed significant weight loss for Good responders, where this is not the case for Poor responders. See figure 5.
Complications Banded Gastric Bypass
The key concerns in performing banded gastric bypass are ring related complications. The fear of erosions and even migrations derives from the initial series of banded bypass, where various materials were evaluated, like e.g. mesh and suture reinforced homemade rings with thick tied knots. Now, with prefabricated and validated rings, like the MiniMizer Ring, these concerns are no longer justified anymore.
“ Overall, the band erosion and removal rates seem to be between 0 and 2% in the long term. Moreover, eroded bands are easily removed endoscopically, though surgery may be required. ”
To prevent the risk of ring removal due to dysphagia or regurgitation, surgeons should take notice not to place the ring too tight around the gastric pouch during surgery.
The MiniMIZER Gastric Ring related complication rate in surgeries is acceptably low and therefore should not be a barrier to withhold patients of the outstanding results that can be achieved in Banded Bariatric Procedures.
