ELIAS, Alexandre Amado et al. Roux-en-y gastric bypass with silicone ring for the obesity treatment: study of the complications related to the ring. ABCD, arq. bras. cir. dig. [online]. 2011, vol.24, n.4, pp. 290-295. ISSN 0102-6720. http://dx.doi.org/10.1590/S0102-67202011000400009.
BACKGROUND: The silicone ring is used as containment factor of the Roux-en-Y gastric bypass to induce greater ponderal loss. However, it may have some inconveniences from this stressed restriction. AIM: To analyze the complications related to silicone ring in patients who underwent Roux-en-Y gastric bypass surgery with silicon ring. METHODS: From 1994 to 2005, 7 000 patients were submitted to Roux-in-Y gastric bypass with silicone ring in order to treat morbid obesity. Only 50% were followed from two to 11 years. The mean excess weight loss was around 85%. But ring complications were registered in 160 patients (2,28% of the total and 4,56% of the followed patients). Therefore, this series consist of 38 male patients (23.8%) and 122 female patients (76.2%) with average age of 44 years old and BMI of 54.4 kg/m2. RESULTS: Five types of ring complications were found. The most frequent was displacement (61%) causing obstructive symptoms. The second most frequent complication was ring erosion to the lumen (22%) causing epigastric pain and nausea. CONCLUSIONS: The ring complications occur in low frequency. Ring removal, either surgical or endoscopically done, is the most usual treatment, but tends to cause partial regain of the weight lost.
