Abstract Laparoscopic Non Banded Sleeve Gastrectomy (NBSG) is a widely popular weight loss procedure that has been around since the start of the millennium. Another variant, the Laparoscopic Banded Sleeve Gastrectomy (LBSG) started to emerge later. Questions have arisen on whether NBSG or BSG have better outcomes on the long run regarding weight loss, weight regain and reflux disease. This study aimed to analyse previous studies performed on this subject and devise a conclusion regarding this matter. This systematic review aimed to scrutinize all English language papers written on the subject of comparing NBSG and BSG and furthermore sought to determine the superior surgery between them regarding long term EWL, weight regain, and regurgitation. Nine papers were included in our review. After thorough analysis of their results, we have concluded that LBSG has better outcomes than NBSG when it comes to Excess Weight Loss and the sustainability of that lost weight. However, we found that LBSG poses a greater risk of post operative complications like regurgitation and reflux than NBSG. Finally, we deduced that there is no sufficient data to decide whether the band has any advantage then the classic sleeve gastrectomy when it comes to resolution of comorbidities like T2DM and HTN. |
