The role of surgery in the treatment of endoscopic complications.

As the number, diversity, and complexity of endoscopic complications has increased, so too has the number, diversity, and complexity of operative interventions required to treat them. The most common complications of endoscopy in general are bleeding and perforation, but each endoscopic modality has specific nuances of these and other complications. Accordingly, this review considers the surgical complications of endoscopy by location within the gastrointestinal tract, as opposed to by complication types, since there are many complication types that are specific for only one or few locations, such as buried-bumper syndrome after percutaneous endoscopic gastrostomy and pancreatitis after endoscopic retrograde cholangiopancreatography, and since the management of a given complication, such as perforation, may be vastly different in one area than in another area, such as perforations of the esophagus versus the retroperitoneal duodenum versus the intraperitoneal duodenum.
