background: Laparoscopic nissen fundoplication is the surgical procedure of choice for patients with gastroesophageal reflux. Aim: To describe the most important surgical stages of the technique and report the rates of complications and mortality. material and methods: In a ten years period, 530 patients were subjec-ted to laparoscopic fundoplication. In all patients a clinical history was obtained and an upper endoscopy with biopsy, esophageal manometry and 24 h pH measurement were performed. Patients with Barret esophagus, hiatal hernia of more than 5 cm and those subjected to other surgical techniques were excluded from analysis. Results: No patient died. The conversion rate was 0.4%. No patient required splenectomy. Two patients had complications and required a second intervention. Mean hospital stay was 2.8 days. Conclusions: Laparoscopic nissen fundoplication is safe and has a low rate of complications.
