RESUMO
BACKGROUND: Laparoscopic fundoplications are the standard surgical treatment of patients with gastroesophageal reflux disorder. Adequate technique is the most important outcome factor. There is no standardized method to evaluate the procedure itself. Intraoperative endoscopy is a method to evaluate laparoscopic fundoplications. MATERIAL AND METHODS: This was a retrospective observational study of patients undergoing laparoscopic fundoplications from July 1999 to June 2004, excluding open procedures and reoperations of previous failed laparoscopic fundoplications. Intraoperative endoscopy was performed during the dissection and suturing of the procedure to determine if correction of the technique is necessary. Number of changes were recorded and analyzed with Student's t-test. RESULTS: Three hundred patients were operated on, 23 were excluded (14 reoperations and nine conventional laparotomies). Of the 277 patients included, 178 were males and 99 females. Average age was 43.4 +/- 14 years (range: 12-85). There were 71 Toupet and 206 Nissen fundoplications. Intraoperative endoscopy determined correction of the technique in 77 patients with 1.69 +/- 0.96 changes; 68 rotated and/or angled fundoplications, one rotation with distended stomach, one redundant gastric fundus, and seven change in the type of fundoplication from Nissen to Toupet because of tightness (3.7 +/- 1.1 changes, p = 0.0001) to achieve adequate fundoplication. CONCLUSIONS: Intraoperative endoscopy confirms adequate technique and prevents inadequate laparoscopic fundoplications. Further studies will determine if routine use is justified to prevent postoperative complications and to improve outcome.
