Imperial College London, Hammersmith Hospital, Department of Investigative Medicine London United Kingdom; 2Imperial College London, Hammersmith Hospital, Imperial Kidney and Transplant Institute London United Kingdom Background Long-term complications after laparoscopic gastric banding (LAGB) are frequent and lead to reoperations in a substantial number of patients. It is not known whether esophageal motility or the lower esophageal sphincter play a role in the development of complications. We compared the results of preoperative upper gastrointestinal (GI) testing and the outcome after LAGB. Methods 68 bariatric patients had esophageal manometry, endoscopy and pH monitoring. prior to LAGB. In 61 patients (90% follow-up) the differences in weight loss, complications and reoperation rate were retrospectively compared. Result 8.2% of the patients had a non-specific motility disorder of the esophagus, 44.3% had an incompetent sphincter on manometry, and 17.5% had acid reflux on pH monitoring. Endoscopic evaluation revealed esophagitis in 10.3% and hiatal hernia in 33.8%.. Abnormal pH monitoring and endoscopic findings were not predictive for the long-term outcome or complications. Presence of an incompetent lower esophageal sphincter (LES) led to reoperation in a greater number of patients (44.4% vs. 14.7%, p=0.01), especially if the band was placed using the pars flaccida technique. Conclusion pH monitoring and endoscopy do not predict outcome of gastric banding and have therefore no relevance in selecting patients for gastric banding. Patients with an incompetent LES on manometry had a higher reoperation rate. If this finding can be confirmed, patients with LES incompetence may need another intervention.

Italian Group For Lap Band Citta` della Scienza, Naples Italy

Background Aim of this study is the retrospective multicenter analysis of the results of perigastric and pars flaccida band positioning. Methods Data were collected from the data base of the Italian Group for LapBand (GILB). Patients operated from January 2001 to December 2004 were selected according to criteria of case-control studies to compare two different positioning techniques: Perigastric (PG-group) and Pars-Flaccida (PF-group). Laparotomic conversion, postoperative complications and weight loss parameters were considered. Data were expressed as mean ± standard deviation. Fisher’s exact test was used for statistics (p
