16 Conclusions 1 Preliminary study (6 months) In our study the new-HAGA LAGB (Heliogast System) for morbid obesity is a safe and well reproducible procedure for all the four different techniques we used. In all groups we found an efficacy in the BMI and EWL trends at 3 and 6 months. Our results were similar or even better than the International HAGA LAGB results.

17 Conclusions 2 Long-term study (24 months December 2010) From Mars 2009 to December 2010 we operated of new-HAGA LAGB (Heliogast System) 528 patients: 513 pts. with “pars flaccida”technique and anterior fixation 15 pts. with “two-steps perigastric” technique and anterior fixation Centro per lo Studio, la Ricerca e la Terapia dell’Obesità. C.S.R.T.O. Direttore dott. P. Pizzi Long-term study (24 months) From Mars 2009 to December 2010 we operated of new-HAGA LAGB (Heliogast System) 528 patients: all patients with anterior fixation. NO SLIPPAGES extra study group

18 Conclusions 3 Long-term study (36 months December 2011) 128 pts 15:113 = M:F From September 2008 to December 2011 we operated with the new- HAGA LAGB (Heliogast System) 912 patients for morbid obesity. 8 pts. (study group of 154 pts.) with slippages (1 pt. with anterior fixation and 7 pts. without anterior fixation). 3 pts. (extra study group of 154 pts.) with slippages ( all with anterior fixation and old HAGA). Long-term study (24 months December 2010) From September 2008 to December 2010 we operated with the new-HAGA LAGB (Heliogast System) 682 patients for morbid obesity 4 pts. (study group of 154 pts.) with slippages (all pts. without anterior fixation).

19 Conclusions 4 Long-term study slippages (24 months December 2010) 132 pts. 17:115 = M:F 3 pts. Female and 1 pt. Male with complications (slippage) 1° pt.(F): 8 months after surgery 2° pt.(F): 9 months after surgery 3° pt.(F):20 months after surgery 4°pt.(M):15 months after surgery Centro per lo Studio, la Ricerca e la Terapia dell’Obesità. C.S.R.T.O. Direttore dott. P. Pizzi Long-term study slippages (36 months December 2011) 128 pts. 15:113 = M:F December pts. (3 F, 1 M) without anterior fixation December pts. (M) with anterior fixation 3 pts ( 2M, 1F) without anterior fixation

20 Conclusions 5 Long-term study slippages (36 months December 2011) 128 pts. 15:113 = M:F 4 pts. Female and 4 pt. Male with complications (slippage) 1° pt.(F): 8 months after surgery 2° pt.(F): 9 months after surgery 3° pt.(M):15 months after surgery 4°pt.(F):20 months after surgery 5° pt.(M):22 months after surgery 6° pt.(M):23 months after surgery 7° pt. (F): 29 months after surgery 8° pt.(M):31 months after surgery Centro per lo Studio, la Ricerca e la Terapia dell’Obesità. C.S.R.T.O. Direttore dott. P. Pizzi Long-term study slippages (48 months December 2012) 120 pts. 12:108 = M:F From September 2008 to December 2012 we operated with the new- HAGA LAGB (Heliogast System) 1193 patients for morbid obesity. 2 pt. Female with complications (slippage, all without anterior fixation and “pars flaccida” technique)

21 Conclusions 6 Long-term study slippages (48 months December 2012) 120 pts. 12:108 = M:F From September 2008 to December 2012 we operated with the new- HAGA LAGB (Heliogast System) 1193 patients for morbid obesity. 2 pt. Female with complications (slippage, all without anterior fixation and “pars flaccida” technique) Centro per lo Studio, la Ricerca e la Terapia dell’Obesità. C.S.R.T.O. Direttore dott. P. Pizzi Long-term study slippages (48 months December 2012) 120 pts. 12:108 = M:F 10 slippages 9 pts. without anterior fixation 1 pt. with anterior fixation

22 Conclusions 7 From October 2010 we utilize an stitch under new-HAGA between the gastric greater curvature, gastric body and lesser gastric curvature. We feel that this technique decrease the number of slippages. We performed a randomized study in 100 patients operated with the new-HAGA (Heliogast System) LAGB for morbid obesity with “pars flaccida” technique, all without anterior fixation: 50 pts. with stitch and 50 pts. without stitch under band. A longer follow-up will give us the chance to evaluate the incidence of slippages.
