Official title: A Ten-Year Cohort Study of Clinical and Surgical Predictors for Hypocalcemia Post-Thyroidectomy

Run by Minia University · NCT07428057 · Data updated 2026-11-12

This project will see if clinical, lab, and surgical factors predict low calcium after thyroid surgery in adults treated at Minia University Hospital from 2014–2024.

Is this trial a fit for you?

Likely a good fit

Adults (age ≥18) who underwent thyroidectomy at Minia University Hospital between 2014 and 2024 with complete surgical and postoperative records, documented postoperative calcium levels, and at least 6 months of follow-up or a documented outcome.

Probably not a fit

Patients under 18, those with preexisting parathyroid disorders, chronic kidney disease stage 3 or higher, malabsorption syndromes, prior neck irradiation, concurrent planned parathyroidectomy, chronic medications that strongly affect calcium metabolism, or incomplete records are excluded and unlikely to benefit from this analysis.

What this trial studies

This is a single-center retrospective cohort review of all adults who underwent total, subtotal, or completion thyroidectomy at Minia University Hospital between January 1, 2014 and December 31, 2024. Investigators will extract demographics, preoperative labs (calcium, vitamin D, PTH, thyroid tests), surgical details (extent of surgery, lymph node dissection, surgeon experience, operative time, parathyroid identification/autotransplantation), postoperative calcium/PTH measurements, supplementation needs, and pathology findings. Univariate analyses will screen potential predictors and multivariable logistic regression will be used to identify independent risk factors for transient and permanent postoperative hypocalcemia. The goal is to generate local risk stratification data to guide perioperative management and patient counseling.

Why it matters

Potential benefit: If successful, the findings could help clinicians identify patients at higher risk for post-thyroidectomy low calcium and tailor monitoring and supplementation to reduce symptoms and the chance of permanent hypocalcemia.

How similar studies have gone: Previous retrospective and some prospective studies have identified risk factors for post-thyroidectomy hypocalcemia, so this study mainly provides confirmatory and locally relevant data rather than a novel treatment approach.
