Abstract

Background: Endemic goiter is highly prevalent in Uganda, placing a considerable surgical burden on the healthcare system. Across Africa, prevalence varies widely, reaching 60.2%, with visible goiter affecting 30% of Uganda's rural population despite salt iodization programs. Despite evidence supporting thyroidectomy under local anesthesia (LA) for selected cases, its importance is underestimated moreover with limited access to general anesthesia (GA) and critical care providers in resource-constrained settings. The trial compared outcomes of thyroidectomy under LA versus GA in grade 1-2 uncomplicated euthyroid goiter patients in Uganda, with an aim to assess feasibility of LA as an alternative technique.

Methods: In this prospective equivalence randomized, single-blind controlled trial, participants with grade 1-2 uncomplicated euthyroid goiters were enrolled and randomly assigned to two arms (LA and GA) during surgical camps in Uganda. The study compared early postoperative outcomes, including nausea, vomiting, hematoma formation, transient voice changes, and pain at 6, 12, and 24 h. It also assessed overall incurred material and medication costs, patient satisfaction using a 5-point Likert scale, and willingness to undergo a similar procedure with the same anesthetic technique at 30 days.

Results: Fifty-eight participants undergoing thyroidectomy received random assignment, twenty-nine for each arm. No significant differences were found between the 2 groups in demographics, symptom duration, and early post-operative complications or patients' level of satisfaction (P > 0.05). However, the overall material and medication costs were significantly lower in the LA Group (P < 0.001).

Conclusions: Thyroidectomy under LA can be performed in a well-selected patient population with low complication rates and comparable patient satisfaction to GA. These findings may support LA for thyroidectomy as a valuable cost-efficient alternative, especially in low-resource settings with fewer GA providers.
