Abstract

Aims

To compare the perioperative parameters and excess weight loss between patients operated by laporoscopic Roux-en-Y gastric bypass (LRYGB), as a primary operation or a revisional, for insufficient weight loss after vertical banded gastroplasty (VBG) or adjustable gastric banding (AGB).

Methods

A retrospective analysis of all patients who underwent a LRYGB was performed for the period 2004–2011. Demographics, preoperative body mass index (BMI), co-morbidities, operation time, conversion rate, perioperative complications, hospitalization period, and % of excess BMI loss (%EBMIL) were investigated and compared between groups.

Results

Three hundred forty-two laparoscopic gastric bypass operations were performed, 245 were primary, and 97 revisional. Median follow-up was 30 months (range 0–108 months). Mean BMI (kg/m2) before bypass was 45.2 for primary laparoscopic Roux-en-Y gastric bypass (pLRYGB) and 41.1 for revisional laparoscopic Roux-en-Y gastric bypass (rLRYGB). Median operative time and length of stay were longer for rLRYGB 157.5 versus 235 min (p < 0.001) and 6 versus 6.5 days (p = 0.05). Conversion to laparotomy was performed in eight patients, 0.4% of primary and 7.2% of revisional. Morbidity rate was 6.5% in pLRYGB versus 10% in rLRYGB (NS). There was one death in the primary group. Percentage of EBMIL was significantly lower in the revisional group at 12, 18, and 24 months of follow-up.

Conclusions

Revisional and primary gastric bypass have no statistical differences in terms of morbidity. The % of excess BMI loss is lower after revisional gastric bypass during the first 2 years of follow-up. The trend of weight loss or weight regain was similar in both groups.
