BACKGROUND: Restrictive bariatric operations are efficient with low morbidity but entail high rate of failure on follow up of several years. We present our experience in laparoscopic revision of patients who previously underwent silastic ring vertical gastroplasty (SRVG) into laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (LRYGB).

METHODS: Data on 12 patients who underwent revisional operations after SRVG was prospectively collected. Six patients underwent LRYGB and six patients underwent LSG. The pathogeneses for failures of SRVG were disruption of staple line, enlargement of gastric pouch, and opening of the ring.

RESULTS: The average age and body mass index (BMI) were 39 and 43, respectively, in the LSG group versus average age and BMI of 39 and 45, respectively, in the LRYGP group (p = 0.45 and p = 0.35, respectively). The average operative time were 206 and 368 min in the LSG and LRYGB groups, respectively (p < 0.01). There were five postoperative complications among LSG group versus two complications in LRYGB group (p < 0.01). Patients who underwent LSG suffered from the following complications: staple line leak in two patients, intra-abdominal hematoma in one patient, intra-abdominal collection in one patient, and gastric outlet obstruction in one patient. Anastomotic leak and wound infection were the complications seen among patients underwent LRYGB. All complications were treated conservatively without necessitating immediate reoperations. Follow-up has shown adequate reduction of body weight and improved quality of life in both groups of patients.

CONCLUSIONS: Revisional bariatric operation is a challenging laparoscopic procedure with higher morbidity compared to primary bariatric operations. Morbidity of LSG compared to LRYGB as a revisional procedure for SRVG is significantly higher.
