Revisional bariatric surgery typically applies to planned reoperations for either inadequate weight loss, or for
problems inherent to the original surgery which did not manifest early on. Having another operation to address
something related to an original bariatric procedure is probably not high on any patient’s postoperative
expectations list. These procedures are best carried out by more experienced bariatric surgeons at facilities that
can provide the necessary support, like those we feature here at University Bariatrics. The high level of skill
necessary to perform these operations makes the experience and a proven track record of excellence a must.
Types of Revisional Surgery Offered by University Bariatrics:
Vertical Banded Gastrectomy Revisional Surgery:
The vertical banded gastroplasty was a popular operation in the 1980s and early 90s. The stomach was
partitioned but not fully divided into two segments. The smaller portion was further restricted by the placement of
a band at its end to obstruct oral intake and cause early satiety. Intestinal rerouting was not utilized. Gradually,
VBG was abandoned in favor of the gastric bypass procedure, in part due to complications related to the band or the staple line. The University Bariatrics team has performed several laparoscopic revisional surgeries
including full reversal or conversion to the gastric bypass.
Vertical Sleeve Gastrectomy Revisional Surgery:
Laparoscopic conversion of sleeve gastrectomy to gastric bypass is typically carried out for technical
complications seen in poorly performed sleeves, incomplete resolution of comorbidities, or side effects such as
reflux unresponsive to medical therapy. Typical revision is a conversion to a gastric bypass or rarely, a re-
Roux-En-Y Gastric Bypass Revisional Surgery:
Complete reversal of the RYGB is rarely performed but may be necessary in cases of medical or surgical side
effects refractory to conservative therapy. The University Bariatric team has successfully performed these
Goals/Motivation for General Revisional Surgery:
Multiple procedures have been introduced by the industry to address ongoing and lingering issues after
surgery. Their common goal is to provide additional restrictions by adding foreign bodies, tightening, or even
re-stapling/trimming gastric pouches and surgical anastomoses. Although the stretching of surgical areas is
a natural and well-described phenomenon, the extent of its influence on recidivism is debated.
Revisional intervention can include the placement of rings or even Lap Bands around them. Endoscopic suturing
of pouches and surgical hookups can be performed as well. Whereas their short-term results have held
promise, most have been ineffective in the longer run. Foreign bodies left behind as part of these procedures,
furthermore, will impede the safe application of surgical staplers during their ultimate conversion to gastric
bypasses and duodenal switches.
The University Bariatrics team believes that by playing on patients' hopes and fears, some programs tend to
overstate potential benefits without giving much detail on side effects and alternatives. The resolution and
improvement of medical comorbidities are the primary objectives of the bariatric surgery we perform and not
an idealized final weight. Focusing on the latter, furthermore, can lead to the very same issues and coping
mechanisms that resulted in morbid obesity in the first place. Inadequate weight loss and significant weight
regain are multifactorial issues that often do not lend themselves to just adding more surgery. It requires a
more fundamental approach to the whole patient, which our multidisciplinary group is able to offer.
