New adjustable gastric bands available in the United States: a comparative study

Clinical outcomes of the REALIZE adjustable gastric band-C at one year in a U.S. population

“…In contrast, a single-institution, retrospective analysis [29] reported that the %EWL was greater with the RB than with the RB-C at 1 year. However, the average %EWL observed in our study (near 40%) was greater than the 32% EWL with the RB-C and comparable to that with the RB (39%) reported in that single-site study [29].…”

“…In the present study, the average fill volume at 12 months was 8.0 mL, with 1 of 158 patients exceeding the maximal fill volume [15] by .1 mL ( Table 2). The single-site study reported a greater average fill volume (10.2 mL) and 38% overfills [29].…”

“…The single-site series reported the combined characteristics of the RB-C patients who did and did not have complete 1-year data available [29]. Therefore, no direct comparisons could be made between their study and ours.…”

“…Therefore, no direct comparisons could be made between their study and ours. Nonetheless, to our knowledge, the single-site report [29] is the only other %EWL ϭ percentage of excess weight loss; COE ϭ Center of Excellence; LAGBs ϭ laparoscopic adjustable gastric bands; RB-C ϭ REALIZE band-curved; IBF ϭ initial band fill; GI ϭ gastrointestinal; SBF ϭ subsequent band fill; SD ϭ standard deviation; BMI ϭ body mass index. * Data obtained by standardized questionnaire completed by surgeons before data analysis; items in which all centers were similar are not listed.…”

“…These behaviors (known as maladaptive eating) are not conducive to weight loss [30 -32]. In the single-practice study [29], the RB-C patients might have been unintentionally titrated to the more aggressive band fills typically used with higher pressure bands. Most patients in our study required 3-7 SBFs, consistent with what we have observed with the RB.…”
