Background
This study was conducted to investigate diabetes mellitus (DM) resolution after gastrectomy according to reconstruction type in gastric cancer patients.
Methods
Two hundred twenty-nine gastric cancer patients with DM who underwent gastrectomy with curative intent from May 2003 to December 2009 were enrolled. Changes in fasting blood sugar concentration and the dosage of oral hyperglycemic agents or insulin were compared between reconstruction types.
Results
The numbers of patients who underwent distal gastrectomy with a Billroth I (BI), Billroth II (BII), Roux-en-Y gastrojejunostomy (RYGJ), or total gastrectomy with Roux-en-Y esophagojejunostomy (RYEJ) were 119 (51.7%), 54 (23.5%), 40 (17.4%), and 16 (6.9%), respectively. DM remitted in 45 (19.7%) patients: 18 BI patients (15.1%), 11 BII patients (20.3%), 8 RYGJ patients (20.0%), and 8 RYEJ patients (50.0%). DM improved in 85 (37.1%) patients: 41 BI patients (34.4%), 25 BII patients (46.2%), 15 RYGJ patients (37.5%), and 4 RYEJ patients (25.0%). The DM remission or improvement rate was higher in the duodenal bypass group (BII, RYGJ, RYEJ) than in the BI group (67.2% vs. 49.5%, P = 0.022), and the DM remission rate was higher in the RYEJ group than in the distal gastrectomy group (50.0% vs. 17.3%, P = 0.002).
Conclusions
Many gastric cancer patients with DM who received a gastrectomy showed remission or improvement of DM. The duodenal bypass group had higher DM remission or improvement rate than the BI group, and the RYEJ group had the highest DM remission rate.
