Abstract:
We describe the rare complication of an eroded gastric band in the gastric cavity that passed through the pylorus and obstructed the proximal jejunum at the point allowed by the length of the connecting tube. At surgery, in addition to the expected finding, multiple necrotic pressure ulcerations in the jejunal wall were found in step ladder locations. Anyone who has adopted laparoscopic gastric banding as the modality for surgical treatment of morbid obesity should be familiar with this rare but potentially dangerous complication.
