Abstract

Background: Silastic ring vertical gastroplasty (SRVG) is a simple, effective and reproducible restrictive operation for the treatment of morbid obesity. Over the last years, it has lost its popularity due to the development of adjustable gastric banding systems performed laparoscopically. In order to evaluate the long-term effect of SRVG on weight loss and co-morbidities, we reviewed the results of SRVG operations in our institution. Methods: We reviewed SRVG operations performed in our University-affiliated General Hospital. Data was collected from the patients' in-patient records, their outpatient-clinic files, and from a telephone interview. Results: Between 1989 and 2001, 162 patients were operated upon. Complete follow-up was obtained of 115 patients (71%). The mean follow-up was 7.1±3 years (range 4 to 16 years). Mean preoperative BMI was 47 kg/m2 (range 34 to 69 kg/m2). Maximal weight loss was obtained within 1 year to a mean BMI of 29 kg/m2, with a mean excess BMI loss of 67%. Subsequently, there was a small increase in BMI, which stabilized at 34 kg/m2 up to 15 years after the operation. A rapid, significant improvement in obesity-related co-morbidities was observed regarding hypertension (81%), diabetes (100%), sleep disorders (90%), osteoarthritis (83%) and ischemic heart disease (75%). There was no peri-operative mortality. Early complication rate was 10%. Late complications included postoperative ventral hernia (18%), esophagitis (31%), ring stricture (19%), ring erosion (2 patients), failure of staple line (8%) and obstruction of the pouch with food (19%). 35 patients (30%) required another procedure, 8 of them were eventually converted to other bariatric operations, and 2 patients had the ring removed and refused another bariatric procedure. The overall satisfaction rate was 86%. Conclusions: SRVG is a simple, safe and effective bariatric operation in selected patients with morbid obesity. It results in a rapid, excellent effect on obesity-related co-morbidities and good long-term effect in weight loss, which compares positively with other, more complicated bariatric operations.
