Good question but I have not come across any discussion.I also had similar doubt. Technically speaking both are almost similar except bile reflux is probably less in DJB and the length of BP limb.Let us see what others opine. 

OK Sir, thanks

ı think that, sleeve gastrectomy is easyly than other obesty surgical technic, and iys complicacion early

ı think that, sleeve gastrectomy is easily than other obesity surgical technique, and its early and late complication are less than other techniques. I have chosen robotic sleeve gastrectomy...

 single anastomosis DJB-SG is a high pressure system due to presevation of the pylorus which will prevent bile reflux but  it's technical challenge procedure in morbid obese patient and complication rate higher. On the other hand, mini gastric bypass is low pressure system with potential bile reflux but the complication rate is lower and easier to manage. furthermore, its a versatile procedure which you can convert to other procedure. it is the best procedure is super obese patient compared to RYGB

Thanks very much  Dr.Hong.

In DJB-SG , gastric sleeve length is more than in mini-bypass - there's no other difference. What exactly is the reason for one being high pressure & the other low pressure ? Is it the presence of pyloric sphincter ?

Yes. the presence of sphincter render it to be higher pressure just like sleeve gastrectomy, thus any leak is difficult to heal

It is not a similar procedure, even if initially seemed to be. In SADI (duodeno jejunal bypass) with sleeve there is the resection of gastric fundus, different from MGB ( mini gastric bypass). I agree that the risk of complication is different especially in the long term. The third difference between these 2 procedures was the promotors. In my opinion the MGB has a good potential for diabetic patients and it seems to have better results than the standard RYGBP. The SADI should be offered as revisional procedure in case of weight loss failure after sleeve.

THanks very much Dr.Nedelcu, that was helpful
