The objective of this study is to explore the preliminary application for laparoscopic sleeve gastrectomy plus jejunum bypass in the treatment of morbid obesity.

Bariatric data for 33 cases in the people′s hospital of XiaoLan in Zhongshan city was retrospectively reviewed from Oct. 2014 to Jun. 2016, according to the different surgery methods, patients were divided into laparoscopic sleeve gastrectomy (LSG) group, laparoscopic Roux en - Y gastric bypass (LRYGB) group and LSG+ JJB group, there were 10 cases in LSG group (1 male, 9 female), the average age was (35.2 ± 12.6) years; 13 cases in LRYGB group (5 male, 8 female), average age was (39.6 ± 8.8) years; 10 cases in LSG+ JJB group (7 male, 3 female), average age was (32.1 ± 7.9) years.

One month after surgery, the body mass index (BMI) decrease and the excess weight loss (EWL%) in LSG+ JJB group were (5.0 ± 1.2)kg/m² and(54.7 ± 28.4)% respectively, higher than those in LSG group which were (2.8 ± 1.9)kg/m² and(44.0 ± 22.2)%(t=2.658 1, P=0.007 764); Three month after surgery, the BMI decrease and the EWL% in LSG+ JJB group were (8.6 ± 2.0)kg/m² and(37.9 ± 27.6)% respectively, higher than those in LRYGB group which were (6.8 ± 2.0)kg/m² and(31.7 ± 15.1)% (t=1.858, P=0.039).

Our study showed that LSG+ JJB operation was not very difficult to conduct, which had better effect on weight loss and obesity related complications improvement, the efficacy of short-term was obvious, however, the long-term effect of this technique needs to be further observed.
