Background: The silastic ring gastric bypass (SRGB) was introduced by Fobi in 1989, in an effort to combine the advantages of the Roux-en-Y gastric bypass with those of the vertical banded gastroplasty, while avoiding the disadvantages of each. Methods: The results of our first 64 patients who underwent SRGB with a 5.5 cm ring have been reviewed with particular attention to weight loss, short- and medium-term morbidity and patient satisfaction. Most patients have had regular follow-up, and those not seen during the last 6 months were sent a postal questionnaire. Results: The patients included 52 females and 12 males, ranging in age from 23 to 59 years (median age = 39 years) at the time of surgery. Median preoperative weight, body mass index (BMI) and % excess weight were 126 kg (range 89-253 kg), 44 kg/m2 (range 36-78 kg/m2) and 113 (range 76- 209) respectively. There were no serious postoperative complications and no deaths. Median hospital stay was 7 days (range 5-14 days). Eight patients (13%) are known to have had a staple-line dihiscence. Eighteen patients (28%) have had major difficulties with eating, and in nine (14%) of these the silastic ring has been removed with resolution of the eating problems, but some gain in weight. In the 54 patients with follow-up data at 2 years, median weight was 78 kg (range 55-137 kg), median BMI was 27 kg/m2 (range 20-43 kg/m2) and mean ± SD % excess weight loss was 69 ± 16. After 2 years of follow-up, eight of 54 patients (15%) were unhappy with the results of the procedure. Conclusion: SRGB is an effective, safe and welltolerated procedure for achieving weight loss in the morbidly obese. The principal drawbacks relate to staple-line problems and eating difficulties related to the silastic ring. A 5.5 cm ring is probably too small to be ideal.
