Abstract:
Background: Long-limb Roux-en-Y (LLRY) reconstruction has recently been implemented as an oncometabolic surgery to improve glycemic control following surgery for gastric cancer (GC); however, data on its feasibility are insufficient. We investigated the 1-year outcomes of LLRY reconstruction for glycemic control in patients with type 2 diabetes (T2D).
Methods:
We reviewed the records of 15 patients with GC and T2D who underwent LLRY reconstruction after gastrectomy, with biliopancreatic and Roux limb lengths of 130-250 cm, to improve postoperative glycemic control. The primary outcome was the T2D remission (glycated hemoglobin <6.5% without antidiabetic medication) rate at 12 months postoperatively. The diabetes prediction (DP) score and Korean nationwide average T2D remission rates following GC surgery were compared.
Results:
The mean patient age was 66.5 years (standard deviation [SD] 9.6), mean body mass index was 26.4 kg/m2 (SD 4.4), and mean glycated hemoglobin level was 7.7% (SD 1.5). The overall T2D remission rate was 46.7%. The postoperative T2D remission rate was 12.9% higher than the DP score estimate (33.8%) and 25.7% higher than the Korean national average rate (21%) of T2D remission following GC surgery.
Conclusion:
Our results show that LLRY reconstruction after gastrectomy is an effective oncometabolic surgery for treating T2D and GC.
