Use of ring in gastric bypass surgery: Advantages and disadvantages

Ten Years Experience of Banded Gastric Bypass: Does It Make a Difference?

“…There is no need to calibrate the anastomosis as in the nonbanded GBP category. The more calibrated or narrow the anastomosis, the more the possibility of a stricture [8,12,14]. In our experience, we have had only 1 anastomotic stricture in 900 cases of RY-BGBP (0.11%) and 8 strictures in the nonbanded GBP group (4%), which means that strictures are almost 40 times more frequent in the latter group.…”

“…Only one study, thus far, shows no differences in both groups; however, they have been followed up for only 2 years [10]. Dr. Buchwald finds an EWL of 61.5% in more than 4,204 bypasses [1] after 2 years of follow-up, and Salinas, in a group of 3,500 BGBP patients, shows a %EWL of 83.5% after a 5-year follow-up [11,12]. In our groups of patients, we have a rate of follow-up of around 70% at 10 years.…”

“…There are very few published articles comparing GBP with and without a ring on a long-term basis [12]. It is important to assess not only the %EWL in both these groups, but also the QOL and whether they have vomiting These are patients that had comorbidities corrected at 1 year, but some have recurred at 10 years.…”

“…The ideal ring should be very well tolerated and have a little elasticity, which, even if causing a restriction, allows an easier food intake than that allowed by a rigid band. Different lengths of the bands were used between 4.5 and 7.5 cm long [9,[12][13][14]. When we used to do vertical banded gastroplasty, we started to place a 5.5-cm band, and many patients developed dysphagy.…”
