Duodenojejunal bypass in treatment for 7 cases with non-severe obese type 2 diabetes mellitus / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the efficacy and feasibility of duodenojejunal bypass(DJB)on non-severe obese patients with type 2 diabetes mellitus(T2DM).</p><p><b>METHODS</b>The body mass index (BMI), fasting plasma glucose(FPG), 2h-postprandial plasma glucose(2hPG), fasting insulin(F-ins), fasting c-peptide(F-CP), glycated hemoglobin and hypoglycemic agents dose changes were tested in 7 patients with non-severe obese T2DM undergoing DJB, preoperatively and within 24 weeks after surgery during the follow-up. Data were collected and the clinical outcomes of T2DM were analyzed.</p><p><b>RESULTS</b>In 7 cases of non-obese T2DM who underwent DJB, one patient was weaned off hypoglycemic agents with normal FPG, 2hPG and HbA1c postoperatively. Five required significantly lower dosage. No significant improvement in 1 case. Complete remission rate of hyperglycemia was 1/7, effective rate was 6/7, and effective rate of HbA1c was 5/7. No significant changes in BMI were observed between the preoperative and postoperative phases.</p><p><b>CONCLUSION</b>Plasma glucose level can be markedly reduced by duodenojejunal bypass in non-obese T2DM, independent of weight loss, and the mechanism remains unclear.</p>
