title: Pneumoperitoneum after esophageal cryoablation in a patient with a PEG.
abstract: There is an increasing use of cryotherapy in the gastrointestinal tract for ablation of a variety of lesions. There is only a single reported case of perforation with spray cryotherapy, which was in a patient with Marfan syndrome. In this report, we describe pneumoperitoneum in a patient with a percutaneous endoscopic gastrostomy tube undergoing cryoablation. It is postulated that barotrauma at the percutaneous endoscopic gastrostomy site led to the pneumoperitoneum, and this can occur even with apparently adequate gas-venting procedures.
