Hypocalcemia after thyroidectomy in patients with a history of bariatric surgery.

Background: Hypocalcemia is a common complication after total thyroidectomy. Previous bariatric surgery could be a higher factor risk for hypocalcemia due to alterations in calcium absorption and vitamin D deficiency.

Objectives: To evaluate incidence and factors involved in the risk of hypocalcemia (transient and permanent) and the postoperative outcomes of these patients after total thyroidectomy.

R1 rectal resection: look up and don't look down.

Background: After rectal resection for adenocarcinoma, pathological examination may reveal invasion of the distal margin (DM) and/or a circumferential resection margin of the tumor (CRM-T) or of involved nodes (CRM-N) less than or equal to 1 mm. Such findings transform a planned R0 resection to R1.

Aim: : The aim was to analyze the impact of an R1 resection on prognosis, recurrence rate, and choice of adjuvant treatment.
