Abstract
BACKGROUND: Since March 2003, we have used the Cousin Bioring in our laparoscopic gastroplasty procedures for morbid obesity. The Bioring belongs to the new generation of adjustable gastric bands. The aim of this study is to review our experience with this particular type of band. METHODS: Between March 2003 and March 2010, 316 patients had a laparoscopic implantation of the Cousin Bioring in our department. As many as 169 patients had the operation at least 5 years ago, of which 161 had a complete follow-up. Short- and long-term results were prospectively collected and analysed. RESULTS: There were no intra-operative and only two mild early post-operative complications. Mortality was zero. The mean percent of excess weight loss (%EWL) was 56% at 5 years, 55% at 6 years and 56% at 7 years. Of the 169 patients, four had a band removal for intolerance and/or insufficient weight loss and 11 (6.5%) developed late complications requiring surgery. We managed to solve all complications by minimally invasive procedures without loss of the device. Fifteen of the 169 patients suffered preoperatively from diabetes mellitus type 2. Ten of these had a remission after 5 years. The quality-of-life was assessed 3 years post-operatively for 164 patients and showed an improvement in 83.5% of them. CONCLUSION: Laparoscopic implantation of the Cousin Bioring is a straightforward and safe operation. Complications occur, but they are rather benign and easy to remediate. The mean weight loss is considered successful (%EWL > 50) and persists 5 to 7 years after the operation.
