Problem: Patients with Roux en Y gastric bypass (RYGBP) who undergo total thyroidectomy may be at increased risk for recalcitrant symptomatic hypocalcemia.

Methods: All patients who underwent total thyroidectomy with a history of preceding RYGBP from 2007 to 2012 were identified retrospectively. Cases were matched 2:1 for age, gender, and BMI to a control group undergoing total thyroidectomy without previous RYGBP during the same study period.

Results: Age and body mass index were equivalent between cases (n = 14) and controls (n = 23). A comparison between groups demonstrated that cases had a significantly higher incidence of symptomatic hypocalcemia resulting in paresthesia and tetany (38% vs. 0%; P <0 .01), received intravenous calcium more often (18% vs. 0%; P < 0.01), and had longer hospital stays (2.2 vs. 1.2 days, P = 0.02) than controls.

Conclusions: Physicians and surgeons need to be aware of this complication and take measures to identify and prevent it, and patients should be informed. In this patient population, calcium levels should be closely monitored and early calcium and vitamin D spplementation should be initiated preemptively.
