A 4-year-old boy had a 15-mm atrial septal defect repaired percutaneously with use of an Amplatzer Septal Occluder. At age 16 years, he presented with a week's history of fever, chills, dyspnea, fatigue, and malaise. Cultures grew methicillin-sensitive Staphylococcus aureus. A transesophageal echocardiogram showed a 1.25 × 1.5-cm pedunculated mass on the left aspect of the atrial septum just superior to the mitral valve, and a smaller vegetation on the right inferior medial aspect of the septum. At surgery, visual examination of both sides of the septum revealed granulation tissue, the pedunculated mass, the small vegetation, and exposed metal wires that suggested incomplete endothelialization of the occluder. We removed the occluder and patched the septal defect. The patient returned to full activity after 4 months and was asymptomatic 3 years postoperatively. Our report reinforces the need for further investigation into prosthetic device endothelialization, endocarditis prophylaxis, and recommended levels of physical activity in patients whose devices might be incompletely endothelialized. In addition to reporting our patient's case, we review the medical literature on this topic.

Transoral incisionless fundoplication is a new treatment for patients with gastroesophageal reflux disease. We present our initial experience with 10 patients undergoing this procedure with varying past surgical histories. All procedures were performed under general nasotracheal anesthesia. RAND-36 and Visual Analog Scale symptom scores were collected at pre and postoperative appointments for a mean of 9.2 months. The mean procedure time was 68 minutes. There were no intraoperative or postoperative complications. Patients with prior pancreaticoduodenectomy had observed reduced working space due to prior distal gastrectomy and required additional insufflation due to no pyloric resistance to insufflation of the small bowel. The patient with prior fundoplication required additional time and force for fastener penetration of the resultant scar from the partially disrupted fundoplication. All patients were discharged within 23 hours of the procedure. Throughout the follow-up period, patients reported gradual changes in medication requirements and symptom scores. There were no late complications. Transoral incisionless fundoplication is technically safe in well-selected patients including those with prior esophageal and gastric surgery.

Gastroesophageal reflux disease (GERD) has a spectrum of presentations and treatment. Mild-to-moderate GERD is treated with lifestyle modification or medication. In more severe cases, formal laparoscopic or open surgical techniques are utilized. More recently, a search for an alternative and less invasive approach for the treatment of moderate-to-severe GERD has incorporated the endolumenal approaches described in this chapter. Despite significant investment, no single endolumenal treatment has enjoyed long-term use to date. Currently, two endolumenal approaches are clinically available and are discussed.
