Laparoscopic gastric clip (GC), a novel pure restrictive procedure, is a safe and effective treatment for morbid obesity. However, whether adding a proximal jejunal bypass (PJB) to this procedure might increase the efficacy is unknown.


Outcomes of 74 (43 women and 31male) obese patients who had undergone PJB-GC (41) or GC (33) for the treatment of type 2 diabetes mellitus (T2D) with 1 year follow-up were assessed. GC consists of creating a transverse gastric partition with a metallic clip. PJB consists of a jejuno-ileostomy between 20 and 320 cm distal to the ligament of Treitz. Postoperative body mass index (BMI) reduction, total weight loss (TWL), and remission rates of T2D were evaluated.


The preoperative clinical characters in both groups were similar. The mean operative time was significantly longer in the PJB-GC group than in the GC group. At 24 months after surgery, the BMI was lower (32.5 ± 6.2 vs. 37.0 ± 5.9 kg/m2, p = 0.002) and weight loss higher in PJB-GC than GC (TWL 31.3 ± 14.8 vs. 23.5 ± 10.4%, p = 0.011). Remission of T2D was greater in the PJB-GC group (90.2 vs. 57.2%; p < 0.001).


In this study, PJB-GC was superior to GC in weight loss and T2D remission at 1 and 2 years after surgery. Adding PJB to GC increased the effect of weight loss and diabetic control.
