RESUMO
BACKGROUND: Vertical gastroplasty (VG) was worldwide and until recently a very popular restrictive bariatric procedure. Unfortunately, many patients required revisional surgery for failure of this technique. The present study aimed to evaluate retrospectively the feasibility, safety, and efficiency of conversion of failed VGs to laparoscopic adjustable gastric banding (LAGB). METHODS: Forty patients underwent LAGB as revisional surgery between August 2001 and June 2008. Preceding VGs were performed either by open procedure {silastic ring vertical gastroplasty (SRVG, n = 21) and vertical-banded gastroplasty (VBG, n = 10)} or by laparoscopy {laparoscopic silastic ring vertical gastroplasty (L-SRVG, n = 9)}. The delay between initial and revisional surgery was significantly shorter for SRVG (5.5 +/- 1.7 years; p < 0.001) as compared to VBG and L-SRVG (9.2 +/- 2.3 and 9.4 +/- 1.8 years, respectively). The reasons for failure of the VG were: disruption of the staple line (n = 23), excessive enlargement of the gastric pouch (n = 15) and inefficient stoma (n = 2). Patients were qualified for revisional surgery in case of uncontrolled weight regain with or without frequent vomiting. RESULTS: There were three conversions from laparoscopy to laparotomy (7.5%). There was no mortality. Minor morbidity was 12.5%. There were two major complications (5%); one incarcerated port-site hernia requiring small bowel resection, and one band erosion necessitating band removal. The mean BMI dropped from 38.9 kg/m(2) before revision to 30.7 kg/m(2) after conversion to LAGB (follow-up 6-88 months). CONCLUSIONS: Conversion of failed VGs to gastric banding is safe and efficient. The morbidity rate is acceptable. Gastric banding to correct failing VG is a reasonable option when performed in selected patients.
