Abstract
Historically, surgical gastrostomies, gastrojejunostomy, and percutaneous endoscopic gastrostomy have been used palliatively. Recently, enteral stenting has also provided a means of reestablishing gastrointestinal flow in proximal and colonic obstructions. Seven patients with known intraabdominal malignancy leading to gastrointestinal obstruction were evaluated for PTEG. Ultrasonography, fluoroscopy, and a rupture-free balloon were used in placement. An endoscope was not used. Consent was obtained from all patients. The procedure was performed by a single surgical endoscopist in an endoscopy suite. Patients had appropriate hemodynamic monitoring with pulse oximetry, and they were given preprocedure antibiotics and sedation. PTEG was successfully placed and alleviated symptoms in all seven patients. One complication occurred; in the fourth patient subcutaneous emphysema developed on postoperative day 1, and was managed nonoperatively. All patients were discharged from the hospital. PTEG is a safe and effective technique for decompression in malignant gastrointestinal obstruction.
