RESUMO
INTRODUCTION: Hypocalcemia following total thyroidectomy is common due to postoperative parathyroid dysfunction. We sought to identify the impact of obesity on postthyroidectomy hypocalcemia. METHODS: We performed a single-center retrospective study of all total thyroidectomies performed from 2016 to 2019 after implementation of an updated calcium supplementation protocol. Patient characteristics and outcomes were measured including body mass index (BMI), postoperative hypocalcemia (Ca <8.3), and hypocalcemic symptoms. RESULTS: Overall, 559 total thyroidectomies were performed. A total of 146 patients (26.2%) developed hypocalcemia requiring supplementation adjustment and 116 patients (20.8%) developed mild hypocalcemia symptoms. On multivariable analysis, younger patients, patients with lower preoperative calcium, and lower BMI were more likely to develop postoperative hypocalcemia (all P < 0.05). Similarly, younger patients and patients with BMI <25 were more likely to develop hypocalcemic symptoms (all P < 0.05). CONCLUSIONS: Younger age and lower BMI were associated with increased risk of hypocalcemia after total thyroidectomy. These patients may benefit from preoperative and/or increased postoperative supplementation.

BACKGROUND: Adhesive small-bowel obstruction (SBO) is a common surgical condition accounting for a significant proportion of acute surgical admissions and surgeries. The implementation of a high-osmolar water-soluble contrast challenge has repeatedly been shown to reduce hospital length of stay and possibly the need for surgery in SBO patients. The effect of low-osmolar water-soluble contrast challenge however, is unclear. The aim of this study is to evaluate the outcomes of an SBO pathway including a low-osmolar water-soluble contrast challenge. METHODS: A prospective cohort of patients admitted for SBO were placed on an evidence-based SBO pathway including low-osmolar water-soluble contrast between January 2017 and October 2018 and were compared with a historical cohort of patients prior to the implementation of the pathway from September 2013 through December 2014. The primary outcome was length of stay less than 4 days with a secondary outcome of failure of nonoperative management. RESULTS: There were 140 patients enrolled in the SBO pathway during the study period and 101 historic controls. The SBO pathway was independently associated with a length of stay less than 4 days (odds ratio, 1.76; 95% confidence interval, 1.03-3.00). Median length of stay for patients that were successfully managed nonoperatively was lower in the SBO pathway cohort compared with controls (3 days vs. 4 days, p = 0.04). Rates of readmission, surgery, and bowel resection were not significantly different between the two cohorts. CONCLUSION: Implementation of an SBO pathway using a low-osmolarity contrast is associated with decreased hospital length of stay. Rates of readmission, surgery, and need for bowel resection for those undergoing surgery were unchanged. An SBO pathway utilizing low-osmolarity water-soluble contrast is safe and effective in reducing length of stay in the nonoperative management of adhesive small-bowel obstructions. LEVEL OF EVIDENCE: Therapeutic study, level IV.
