In this series, robotic and conventional approaches were similar in complication rates, operating time, and length of postoperative hospital stay. However, for patients with a preoperative BMI≥50 kg/m2, the operating time is significantly shorter using the robotic approach despite the adoption of this new technique. These data suggest that the robotic approach is at least as safe as the conventional laparoscopic approach in LAGB, and that the robotic approach should be considered for gastric banding candidates with BMI≥50 kg/m2.

Objective To characterize the relationship between hemoglobin A1c (HbA1c) levels and glucose tolerance across pregnancy and postpartum. Design and Participants In a longitudinal study of pregnant women with gestational diabetes risk factors (N = 102), we performed oral glucose tolerance testing (OGTT) and HbA1c measurements at 10–15 weeks of gestation, 24–30 weeks of gestation (N = 73), and 6–24 weeks postpartum (N = 42). Complete blood counts were obtained from clinical records. We calculated HbA1c-estimated average glucose levels and compared them with mean OGTT glucose levels (average of fasting, 1- and 2-hour glucose levels). Linear mixed effects models were used to test for longitudinal changes in measurements. Results Mean OGTT glucose increased between 10–15 and 24–30 weeks of gestation (β = 8.1 mg/dL, P = .001), while HbA1c decreased during the same time period (β = –0.13%, P < .001). At 10–15 weeks of gestation and postpartum the discrepancy between mean OGTT glucose and HbA1c-estimated average glucose was minimal (mean [standard deviation]: 1.2 [20.5] mg/dL and 0.16 [18.1] mg/dL). At 24–30 weeks of gestation, the discrepancy widened (13.2 [17.9] mg/dL, β = 12.7 mg/dL, P < .001, compared to 10–15 weeks of gestation, with mean OGTT glucose being higher than HbA1c-estimated average glucose). Lower hemoglobin at 24–30 weeks of gestation was associated with a greater discrepancy (β = 6.4 mg/dL per 1 g/dL lower hemoglobin, P = .03 in an age- and gestational age-adjusted linear regression model). Conclusions HbA1c accurately reflects glycemia in the 1st trimester, but underestimates glucose intolerance in the late 2nd trimester. Lower hemoglobin level is associated with greater underestimation. Accounting for gestational age and maternal hemoglobin may improve the clinical interpretation of HbA1c levels during pregnancy.

The American College of Surgeons/Association of Program Directors in Surgery National Surgical Skills Curriculum can be implemented in its totality as a 4-week consecutive surgical simulation rotation in an inanimate setting, leading to global enhancement of junior surgical residents' technical skills and contributing to attainment of Accreditation Council for Graduate Medical Education core competency.
