Background

The metabolic effect of LSG-PJB was referred in many studies. Since, there is no published study for LSG-PJB in Korea yet, our center try to analyze it.

Methods

This is a retrospective study to compare the outcomes between LSG and LSG-PJB. We enrolled patients who underwent bariatric and metabolic surgery at Keimyunng University Dongsan Hospital from January 2019 to July 2023 and excluded patients who lost follow-up at six months.

Results

We enrolled 285 patients, 176 for LSG and 109 for LSG-PJB. The mean age is 36.79 years old. Male is 76 (26.7%). 134 patients have at least one metabolic disease, and 88 patients have T2D. Patients with T2D tended to be received LSG-PJB with bypassing jejunum about 2300cm. There was one postoperative complication for LSG but 4 for LSG-PJB. Both groups decrease body weight significantly. However, excess BMI loss, total body weight loss, excess weight loss and change in BMI were not significantly different. Other metabolic parameters improved, Total cholesterol and HbA1c were statistically different. Moreover, there were no nutrition deficiencies in both groups.

Conclusions

LSG and LSG-PJB is a feasible, safe and effective surgery for treating obesity and diabetes. A long term and randomized control study is still required, but LSG-PJB could be an option as an alternative operation method.
