Brief Summary

Bipolar sealing and cutting devices such as EnSeal® G2 Tissue Sealer are surgical instruments that use electrical powered diathermic energy to seal and transect tissue. These devices have shown high efficiency in a wide variety of open and laparoscopic general and gynecological surgical procedures. The surgical performance of the EnSeal® has shown to be comparable to that of ultrasonic cutting devices in several studies. However, the efficacy of this instrument and in particular of new instruments such as the EnSeal® G2 Tissue Sealer has not been evaluated in thyroid surgery. Our primary aim is to verify whether the EnSeal® performance is superior to the standard surgical technique for thyroidectomy in a randomized clinical trial on 2 different institutions.

Outcome Measures

Primary Outcomes (1)

  • Operative time and surgical safety

    The primary outcomes will be operative time (minutes), blood loss (milliliters), transient and permanent hypoparathyroidism (calcium and PTH levels), loss of signal in laryngeal nerve monitoring, number of ligatures and pain intensity (EVA score).

    One year

Secondary Outcomes (1)

  • Surgical complications

    one year

Study Arms (2)

Thyroid Goiter

EXPERIMENTAL

Benign thyroid disease with a nodule equal or lesser than 4 cm in diameter of any gender or ethnical origin. Half of these patients will undergo either bipolar or conventional thyroidectomy.

Device: Bipolar vessel sealing and cutting deviceProcedure: Conventional thyroidectomy

Papillary Thyroid Cancer

ACTIVE COMPARATOR

Patients of any gender or ethnical origin with papillary thyroid cancer no greater than 4 cm in diameter. Half of these patients will undergo either bipolar or conventional thyroidectomy.

Device: Bipolar vessel sealing and cutting deviceProcedure: Conventional thyroidectomy

Interventions

This device will be used in half of the patients with thyroid goiter and half of the patients with papillary thyroid cancer.

Also known as: EnSeal® G2 Tissue Sealer
Papillary Thyroid CancerThyroid Goiter

Tie and suture technique. This device will be used in half of the patients with thyroid goiter and half of the patients with papillary thyroid cancer.

  • Presence of gross tracheal or laryngeal invasion with thyroid cancer
  • Preoperative vocal cord paralysis or laryngeal disease
  • Patients with bleeding disorders or using anticoagulants
  • Patients with advanced or undifferentiated thyroid cancer
  • Patients with secondary hyperparathyroidism or parathyroid disease
  • Patients who do not want to accept to participate in the study
  • Elimination Criteria:
  • Intraoperative indication of lateral lymph node dissection (radical modified)
  • Intraoperative requirement of any tracheal or laryngeal resection
  • Malfunction of the devices (EnSeal or neuro-monitoring)
  • Any intraoperative conditions of the patient that require to stop or modified the surgery
  • Incomplete records, laboratories or clinical follow-up
  • Patients from vulnerable populations or non-competent to understand or sign the informed consent
