Does hemithyroidectomy still provide any benefit?

OBJECTIVES: Multinodular goiter is a common disorder, found in 5% of the general population. If only one thyroid lobe is affected, hemithyroidectomy may be preferred to total thyroidectomy, to limit the risk of complications and avoid hormone replacement therapy, but incurs a risk of subsequent completion thyroidectomy. The aim of the present study is to determine whether the arguments in favor of hemithyroidectomy are justified and whether it still provides real benefit. METHODS: A retrospective observational study based on prospective data included all patients who underwent surgery for goiter or nodule in our center between September 2010 and September 2014. Rates of hormone replacement 6 months after hemithyroidectomy, postoperative complications and completion thyroidectomy during the postoperative year due to the discovery of carcinoma were analyzed. RESULTS: Four hundred and ninety-three patients were studied: 335 with total thyroidectomy and158 with hemithyroidey. The rate of hormone replacement 6 months after hemithyroidectomy was 84.4%. The rate of definitive hypocalcemia was 6.3% in total thyroidectomy and zero in hemithyroidectomy (P<0.05). There was no significant difference between groups in terms of recurrent laryngeal nerve palsy (1.8% versus 1.9%; P=1) or hematoma (1.2% versus 3.5%; P=0.15). A total of 11.3% of hemithyroidectomies required completion due to discovery of carcinoma (mean interval between surgeries 3.58±2.5 months). CONCLUSIONS: This study suggests that hemithyroidectomy does not in fact avoid the risk of hormone replacement and places the patient at risk of completion thyroidectomy. However, it does avoid a 6% rate of hypocalcemia. We would recommend hemithyroidectomy only in case of single toxic or euthyroid nodule with healthy contralateral lobe and/or refusal of hormone replacement by the patient.

Predictive factors of splanchnic vein thrombosis in acute pancreatitis: A 6-year single-center experience.

OBJECTIVE: Splanchnic vein thrombosis (SVT) is a potentially severe complication of pancreatitis. The aim of this single-center, retrospective cohort study was to investigate the incidence of SVT and to determine the connected risk factors. METHODS: All consecutive patients with acute pancreatitis (AP) managed in our hospital were included. The primary outcome was the occurrence of SVT and data was collected in accordance with Ranson's criteria. RESULTS: A total of 318 patients were included, of whom 124 (39.0%) were women. Biliary lithiasis was the main cause of pancreatitis (n = 156, 49.1%). A total of 19 (6.0%) SVT were identified. In univariate analysis, alcohol intake, smoking and male gender were associated with SVT (P = 0.005, 0.003 and 0.007, respectively). Biological parameters significantly associated with thrombosis were lactate dehydrogenase (LDH) < 500 U/L and hyperglycemia (≥ 10 mmol/L) (P = 0.009 and 0.016, respectively). In multivariate analysis, prothrombin time >75% was a protective factor against thrombosis (OR 0.148, P = 0.019). Leukocytes >10 × 10(9)/L (OR 6.397, P = 0.034), hyperglycemia (≥ 10 mmol/L) (OR 6.845, P = 0.023), LDH < 500 U/L ((OR 22.61, P = 0.001) and alcoholic etiology (OR 8.960, P = 0.041) were risk factors for SVT. CONCLUSIONS: Alcohol intake, male gender and smoking should focus the physician's attention on the risk of SVT. When further associated with certain biological parameters, the physicians should consider therapeutic anticoagulation to prevent SVT.
