IV vs oral calcium for post-resection hypocalcemia

the retrieved evidence does not directly compare IV versus oral calcium for post-resection hypocalcemia, so route selection cannot be settled from this corpus. what it does establish: in small-intestinal resection the hypocalcemia is largely secondary to vitamin D deficiency and malabsorption, and management centers on oral calcium plus vitamin D, with parenteral supplementation reserved for when oral treatment proves insufficient ¹. ^1,4,5

What is known:

• In small-intestinal resection, oral vitamin D and calcium are recommended, with parenteral supplements considered only if oral treatment proves insufficient. ¹
• Calcium absorption after intestinal resection depends on a preserved colon, and hypocalcemia is largely mediated by vitamin D deficiency and secondary hyperparathyroidism. ^4,5
• Correcting the underlying 25(OH)D deficiency is therefore integral to management, not an optional addition to calcium. ^1,4,5

What is unknown / caveats:

• No head-to-head IV vs oral calcium comparison in the retrieved corpus
• Route decision in symptomatic/severe hypocalcemia (tetany, seizures) is not addressed by comparative data here
• Concurrent magnesium deficiency, which impairs hypocalcemia correction, is not quantified in the retrieved sources
• The corpus supports oral calcium plus vitamin D as baseline management but does not define when to escalate to IV calcium.
