Long-Term Results of Bariatric Restrictive Procedures: A Prospective Study
Laparoscopic adjustable gastric b and ing ( LAGB ) and vertical-b and ed gastroplasty ( VBG ) are surgical treatment modalities for morbid obesity . This prospect i ve study describes the long-term results of LAGB and VBG .  One hundred patients were included in the study . Fifty patients underwent LAGB and 50 patients , open VBG .  Study parameters were weight loss , changes in obesity-related comorbidities , long-term complications , re-operations including conversions to other bariatric procedures and laboratory parameters including vitamin status .  From 91 patients ( 91 % ) , data were obtained with a mean follow-up duration of 84 months ( 7 years ) . Weight loss [ percent excess weight loss ( EWL ) ] was significantly more after VBG compared with LAGB , 66 % versus 54 % , respectively . All comorbidities significantly decreased in both groups . Long-term complications after VBG were mainly staple line disruption ( 54 % ) and incisional hernia ( 27 % ) . After LAGB , the most frequent complications were pouch dilatation ( 21 % ) and anterior slippage ( 17 % ) . Major re-operations after VBG were performed in 60 % of patients . All re-operations following were conversions to Roux-en-Y gastric bypass ( RYGB ) . In the LAGB group , 33 % of patients had a refixation or replacement of the b and , and 11 % underwent conversion to another bariatric procedure . There were no significant differences in weight loss between patients with or without re- interventions . No vitamin deficiencies were present after 7 years , although supplement usage was inconsistent . This long-term follow-up study confirms the high occurrence of late complications after restrictive bariatric surgery . The failure rate of 65 % after VBG is too high , and this procedure is not performed anymore in our institution . The re-operation rate after LAGB is decreasing as a result of new techniques and material s. Results of the re-operations are good with sustained weight loss and reduction in comorbidities . However , in order to achieve these results , a durable and complete follow-up after restrictive procedures is imperative
