The Best Time for Completion Thyroidectomy on Differentiated Thyroid Carcinoma: A Literature Review

Background: Completion thyroidectomy is performed for high-risk differentiated thyroid carcinoma; however, the timing of the completion thyroidectomy is a matter of controversy. The current review aimed to assess the best time for completion thyroidectomy in patients with differentiated thyroid carcinoma. Methods: An electronic search was conducted in various databases, such as Pub Med, Google Scholar, Scopus, and Medline, for relevant articles assessing the timing of completion thyroidectomy from the first published article to October 2019. Keywords, “completion thyroidectomy” and “timing” were used. The search was limited to articles published in the English language. Among the 190 articles retrieved, only 11 fulfilled the inclusion criteria. Results: Of the 11 articles included, two were from Europe, one from Africa, one from Australia, and seven from Asia, and all were retrospective studies with the mean duration of studies being 12.71 ± 12.31 years. Five studies (45.5%) showed no effect of timing on the outcomes, two (18.2%) recommended both early and late operation, another two (18.2%) concluded that late operation is better, one (9.1%) found that early surgery is better, while one study (9.1%) stated that the timing of operation should be based on the category of the patient. Conclusions: The results were mixed with some studies recommending late completion thyroidectomy, some observing that both early and late thyroidectomy are safe, while some finding no effect of time on the completion thyroidectomy. Well-designed controlled trials will resolve the issue. Keywords: early completion thyroidectomy, late thyroidectomy, timing

Significance of “ultra-early” rebleeding in subarachnoid hemorrhage

✓ Knowledge of the local incidence of aneurysm rupture permits the conclusion that almost every patient in the population of 933,800 persons served by the authors' institution who was stricken by this catastrophe and survived long enough to be transported was treated at this center (121 patients during 34 months). Of these, 9.1% were admitted late (> 72 hours after subarachnoid hemorrhage (SAH)); of the remaining cases, 94.5% were seen within 24 hours and 50% within 6 hours post-SAH. Of the 121 patients, 10% were neurologically devastated on arrival, a late operation was planned for 19%, and the earliest possible surgery and nimodipine administration was selected for 71%. In this latter group, 50% of the operations were begun within 24 hours and 76% within 48 hours post-SAH. Sixty percent of all mortality and morbidity could be linked to the initial aneurysm bleed. The remaining 40% could be ascribed to potentially avoidable causes of unfavorable outcome. No less than 9.6% of all patients admitted within 24 hours after SAH suffered from “ultra-early” rebleeding during transportation or preparation for operation. The mortality rate from such rebleeding was 7.4%, compared with the 9.1% combined mortality rate from complications and late ischemia.

Early Management of Aneurysmal Subarachnoid Hemorrhage

The Lund Clinic serves a population of 1.46 million inhabitants. During the calendar year 1981, 72 patients presented with a ruptured supratentorial aneurysm, diagnosed either at angiography or at autopsy. Upon admission, 60% of the patients were in good condition and 40% were in poor condition. Eighty-three per cent were admitted within 72 hours after the subarachnoid hemorrhage (SAH). In the total series, 50% made a good recovery; the overall management morbidity was 19%, and the management mortality was 31%. Thirty-one patients in Grades I–III underwent early operation (43% of the total series), with a favorable outcome in 74% and 7% mortality. Of the 35 patients who were admitted early and in good condition, 71% made a good recovery, and the management mortality was 9%. These figures may be compared to the 51% favorable outcome and 27% mortality reported from the Cooperative Aneurysm Study with late operation. In the early operation cases, the incidence of significant arterial narrowing at postoperative angiography performed on Day 9 ± 2 after SAH was 30% and the incidence of permanent neurological deficits of delayed onset was 10%. Two of the early operation patients developed permanent symptomatic hydrocephalus.
