Objectives

It is well known that type 2 diabetes (T2DM) is dramatically improved after bariatric surgery, although the mechanisms have not been clearly identified. The skill required for gastric surgery for gastric cancer is very similar to that needed in bariatric surgery. In this study, we evaluated the immediate improvement of T2DM after gastrectomy for gastric cancer.

Methods

A total of nine patients who were diagnosed with early gastric cancer (EGC) and already had T2DM underwent a 75 g oral glucose tolerance test (OGTT) before surgery and within two weeks after gastrectomy. Glucose, insulin, and c-peptide were measured before, and 30 and 60 minutes after ingesting 75 g of glucose. From these trials, we calculated the HOMA-IR, insulinogenic index, Matsuda index, and area under the curve (AUC).

Results

The mean age of participants was 57.23 ± 11.08 years and eight of them were men. HOMA-IR (4.2 vs. 2.3, P = 0.012) levels were decreased after surgery. There were no significant differences of insulinogenic index, fasting blood sugar before and after surgery. The Matsuda index (3.3 vs. 8.3, P = 0.002) was significantly increased and AUC (512.9 vs. 388.7 mg-hr/dL, P > 0.001) upon 75 g OGTT was significantly decreased after surgery.

Conclusions

Insulin sensitivity was immediately improved after gastrectomy for early gastric cancer in patients with T2DM.

Objectives

Laparoscopy-assisted distal gastrectomy (LADG) is a common surgical procedure that has recently been accepted as safe and feasible for the treatment of early gastric cancer. There have been many efforts to expand the indications of LADG to include the treatment of advanced gastric cancer. The aim of this study was to determine the usefulness of noncompliance rate as an indicator for D2 lymph node dissection (LND) validation in LADG.

Methods

The subjects were 48 patients who underwent distal gastrectomy with D2 LND at Kosin University Gospel Hospital from October to December 2010. Of them, 28 underwent LADG and 20 underwent open distal gastrectomy (ODG). We compared several factors including noncompliance rate to validate D2 LND.

Results

There were no significant differences in clinicopathologic factors except for BMI and tumor depth between the two groups. The average number of retrieved lymph nodes was significantly greater in the ODG group (45.9 ± 2.9) than in the LADG group (35.5 ± 2.0). The noncompliance rate was 43% in the LADG group and 40% in the ODG group with no significant difference.

Conclusions

In terms of no difference of noncompliance rate, LADG with D2 lymph node dissection is a safe, feasible and oncologicallycamparable with open gastrectomy. A large scaled prospective randomized trial should be needed to confirm the benefit of LADG.
