RESUMO
BACKGROUND: Silastic ring vertical gastroplasty (SRVG) was a popular restrictive procedure 2 and 3 decades ago. However, it was associated with severe complications and a high rate of reoperation due to failure. Examination of long-term outcomes of those patients that underwent SVRG is limited. The aim of our study was to determine the long-term outcomes (over 13 years) of SRVG in our institution and to review the literature of long-term outcomes following SVRG. METHODS: Following IRB approval, we reviewed patients who underwent SRVG between 1996 and 2001. Weight loss parameters, preoperative comorbidities, were compared to the follow-up data. RESULTS: In total, 92 patients underwent SRVG, and 89 met the inclusion criteria. Mean age was 52.4 ± 10.6 years and body mass index (BMI) was 46.1 ± 6.5 Kg/m2. Preoperative comorbidities rate included diabetes mellitus (19.1%), hypertension (32.5%), hyperlipidemia (21.3%), joints disease (6.7%), mood disorders (7.8%), and dyspeptic disorders (3.3%). Mean length of follow-up was 208.5 ± 16.8 months. Thirty-eight patients (43%) had to be reoperated due to complications and 24 (30%) had an additional bariatric surgery. Follow-up BMI was 34.2 ± 9.8 Kg/m2 (p < 0.001). There was no improvement in any of the comorbidities; incidence of joint disease and dyspeptic disorders were significantly higher at the follow-up (p = 0.03, p < 0.001, respectively). CONCLUSIONS: SRVG procedure was associated with high rates of reoperations and revisions. The majority of our patients showed poor resolution of comorbidities and even worsening of some. Our data confirms that SRVG is not suitable as a bariatric procedure.
