Abstract
Background: Intraluminal gastric surgery provides a new treatment option for various disease processes. This study assesses the safety of a new large- diameter percutaneous endoscopic gastrostomy (PEG) for intraluminal surgery. Methods: Investigators at six institutions were asked to complete a standard questionnaire to assess the difficulties associated with the assembly and introduction of the PEG, plus intraoperative and postoperative problems related to placement of the device. Results: In terms of assembly; 1.9% of respondents reported difficulty obtaining complete vacuum of the balloon tip, and 3.8% had difficulty fitting the graduated dilator to the balloon-tipped cannula. Difficulties associated with introduction of the PEG included disengagement of the dilator from the balloon-tipped cannula (0%), extraction of the dilator-port assembly (0%), difficult PEG pullout (1.9%), abdominal wall bleeding (0%), and difficult PEG dilator separation (7.5%). Intraoperatively, 7.5% of respondents reported inadequate skin bolster fitting, 1.9% had CO2 leakage into the peritoneal cavity, 0% had inadvertent PEG extraction, and 0% reported injury to the esophagus, colon, or small intestine. Postoperatively, there was a 9.4% rate of wound infection, a 1.9% rate of gastrocutaneous fistula, and a 1.9% rate of esophageal, colon, or small intestine injury. Conclusions: The large-diameter PEG is safe and effective for endo-organ surgery. Additional preventive measures for PEG site infection should be investigated.
