Objective

The aim of this study is to evaluate whether an increased preoperative hemoglobin A1c (HbA1c) is a risk factor for postoperative complications.

Methods

We retrospectively reviewed a database of patients who underwent a laparoscopic sleeve gastrectomy or a laparoscopic gastric bypass. The database was split into two cohort according to the preoperative HbA1c (> or ≤ 7 mmol/l).

Results

We included 250 patients in both groups. There were 31 complications (12.4%) in the group with a preoperative HbA1c ≤ 7 mmol/l and 50 (20%) in the group with a preoperative HbA1c > 7 mmol/l (P = 0.057). The preoperative HbA1c is a predictive risk factor for patients younger than 52 (OR = 1.031, 95%CI (1.009–1.053)/P = 0.005) but not for those older than 52 (OR = 1.009, 95%CI (0.985–1.033)/P = 0.48).

Conclusions

In this study an increased preoperative HbA1c (> 7 mmol/l) was associated with a greater risk for postoperative complications in bariatric patients younger than 52 years old, although the magnitude of this risk may be clinically less relevant.
