The correlation, however, of hypocalcemia after thyroidectomy in patients with previous bariatric surgery has been poorly described. This review aimed to investigate the relationship between history of bariatric operations and post-thyroidectomy hypocalcemia, as well as suggested management options. Materials and Methods: MEDLINE and Cochrane databases were searched for relevant publications regarding post-thyroidectomy hypocalcemia in patients with previous bariatric surgery. Results: A total of 17 publications reporting on 126 patients met the inclusion criteria. These included 13 publications about Roux-en-Y gastric bypass (RYGB), 2 regarding biliopancreatic diversion (BPD), 1 about sleeve gastrectomy (SG) and 1 compared three bariatric procedures: SG, RYGB, laparoscopic adjustable gastric band (LAGB). Post-thyroidectomy hypocalcemia was found to be more prevalent in patients with previous RYGB and BPD, but not in previous LAGB and SG. Conclusion: Patients with previous bariatric surgery are at high risk of post-thyroidectomy hypocalcemia that sometimes leads to higher length of hospital stay and demands more invasive solutions. There is a need, however, for additional studies and further investigation in order to reach more conclusive results.
