Abstract
dc.description.abstract
Abstract Marginal ulcer (MU) is an occasional complication
after gastric bypass which can occur early or late after surgery.
In this study, we evaluated the incidence, clinical presentation,
and endoscopic behavior of patients with late MU. Five
hundred fifty morbidly obese patients were evaluated prospectively
performing an endoscopic study 1–8 years after
surgery. They were submitted either to laparotomic (n=392)
or laparoscopic (n=158) approach. Six patients (1%)
presented late MU 12 to 84 months after surgery. Four
patients had single ulcer, while two patients had multiple
ulcers. All were treated with proton pump inhibitors (PPIs).
Several endoscopic evaluations were performed in each
patient showing healing and no recurrence of the ulcer. Late
MU occurs in a small proportion (1%) of patients submitted
to gastric bypass. It can be single or multiple. Medical
treatment with PPIs achieves healing at a mean time of
7 months. Several endoscopic evaluations should be performed
in these patients in order to demonstrate healing of
the ulcer and no recurrence.
