Abstract
Background: Thyroidectomy is the most common surgical procedure
performed in the neck by surgeons. Hypocalcemia is the most frequent
complication after total thyroidectomy, and it is the main cause of prolonged
hospital stay. The value of routine postoperative oral calcium and vitamin
D supplementation in preventing symptomatic hypocalcemia after total
thyroidectomy is still controversy.
Material & Methods: Two hundred and seventy patients who underwent
total thyroidectomy for goiters were randomly assigned to routinely receive or not
receive oral calcium (3 g/d) and vitamin D (1 μg/d) for 4 weeks post-operatively.
Hypocalcemic symptoms, signs, total serum calcium and parathormone levels
were monitored and compared between two groups.
Results: The incidence of symptomatic and laboratory hypocalcemia was
lower in the group receiving the supplement than in the group not receiving it: 9
of 135 patients (6.7%) versus 45 of 135 (33.3%). The hypocalcemic symptoms
were minimal in the group receiving the supplement but more severe in the
group not receiving it. Serum calcium levels decreased in both groups after
surgery but were lower in the supplemented group.
Conclusion: Routine administration of oral calcium and vitamin D
supplementation is effective in reducing the incidence and severity of
hypocalcemia after total thyroidectomy.

Introduction
Tyroidectomy is the most common surgical procedure
performed in the neck by surgeons. Teodore Kocher recognized
recurrent laryngeal nerve injury, myxedema, and tetany as the three
main postoperative complications of thyroidectomy as early as 1883.
Tetany was attributed to the defciency of thyroid gland until Moussu
(1898) could relieve it with an aqueous extract of parathyroid glands.
Fourman and colleagues (1963) suggested persistent parathyroid
insufciency following transient hypocalcemia [1]. Tey observed
persistent parathyroid insufciency in 24% of patients afer
thyroidectomy based on depression of serum ionized calcium level by
the ethylene diaminetetraacetic acid (EDTA) infusion test [2].
Te immediate manifestations of hypocalcemia are mostly neuro-
muscular symptoms and occasionally psychotic states. Ectodermal
changes leading on to alopecia, eczema, and cataract may occur as
early as 6 months afer the operation. Persistent hypocalcemia may
cause intracranial lesions and cardiac arrhythmias. Permanent
hypocalcemia causes a substantial impact on the health of patient
along with the considerable fnancial loss.
Te prevention of signifcant symptomatic hypocalcemia will
allow early discharge of post-thyroidectomy patients from the
hospital [3]. A combined measurement of iPTH “intact parathyroid
hormone” and serum calcium levels is recommended to identify
patients at risk for developing hypocalcemia. Severe, progressive
hypocalcemia is unlikely with a normal iPTH level, and thus iPTH
can be used cautiously to facilitate early discharge for many patients
[4].
Routine oral calcium and vitamin D supplements have been
proposed to prevent the development of symptomatic hypocalcemia
and to increase the likelihood of early hospital discharge afer
bilateral surgical treatment of the thyroid gland or exploration of the
parathyroid glands [5,6].
Materials and Methods
Tis study included 270 (two hundred and seventy) patients
sufering from thyroid enlargement who were admitted to the
Department of Surgery at Alexandria and Kafrelsheik University
hospitals, during a period from January 2016 to December 2017
excluding those patients sufering from chronic renal failure and
parathyroid gland diseases.
All patients included in this study were subjected to complete
history taking, full clinical examination, serum T3, T4, TSH,
Ultrasound neck. Blood samples were taken from every patient
