Tracheostomy after total thyroidectomy: indications and results in a series of 3214 operations

Does the continuation of low-dose acetylsalicylic acid during the perioperative period of thyroidectomy increase the risk of cervical haematoma? A 1-year experience of two Italian centers

BACKGROUND

A growing number of patients taking antiplatelet drugs, mainly low-dose acetylsalicylic acid (ASA) (75-150 mg/day), for primary or secondary prevention of thrombotic events, are encountered in every field of surgery. While the bleeding risk due to the continuation of these medications during the perioperative period has been adequately investigated in several surgical specialties, in thyroid surgery it still needs to be clarified. The main aim of this study was to assess the occurrence of cervical haematoma in patients receiving low-dose acetylsalicylic acid, specifically ASA 100 mg/day, during the perioperative period of thyroidectomy.

METHODS

Patients undergoing thyroidectomy in two high-volume thyroid surgery centers in Italy, between January 2021 and December 2021, were retrospectively analysed. Enrolled patients were divided into two groups: those not taking ASA were included in Group A, while those receiving this drug in Group B. Univariate analysis was performed to compare these two groups. Moreover, multivariate analysis was employed to evaluate the use of low-dose ASA as independent risk factor for cervical haematoma.

RESULTS

A total of 412 patients underwent thyroidectomy during the study period. Among them, 29 (7.04%) were taking ASA. Based on the inclusion criteria, 351 patients were enrolled: 322 were included in Group A and 29 in Group B. In Group A, there were 4 (1.24%) cervical haematomas not requiring surgical revision of haemostasis and 4 (1.24%) cervical haematomas requiring surgical revision of haemostasis. In Group B, there was 1 (3.45%) cervical haematoma requiring surgical revision of haemostasis. At univariate analysis, no statistically significant difference was found between the two groups in terms of occurrence of cervical haematoma, nor of the other early complications of thyroidectomy. At multivariate analysis, the use of low-dose ASA did not prove to be an independent risk factor for cervical haematoma.

CONCLUSIONS

Based on our findings, we believe that in patients receiving this drug, either for primary or secondary prevention of thrombotic events, its discontinuation during the perioperative period of thyroidectomy is not necessary.

The Use of Harmonic Focus and Thunderbeat Open Fine Jaw in Thyroid Surgery: Experience of a High-Volume Center

Background: In thyroid surgery, achieving accurate haemostasis is fundamental in order to avoid the occurrence of complications. Energy-based devices are currently extensively utilized in this field of surgery. This study aims to compare Harmonic Focus and Thunderbeat Open Fine Jaw with regard to surgical outcomes and complications. Methods: Patients submitted to total thyroidectomy in our center, between January 2017 and June 2020, were retrospectively analysed. Based on the energy-based device utilized, two groups were identified: Group A (Harmonic Focus) and Group B (Thunderbeat Open Fine Jaw). Results: A total of 527 patients were included: 409 in Group A and 118 in Group B. About surgical outcomes, the mean operative time was significantly shorter in Group B than in Group A (p < 0.001), while as regards complications, the occurrence of transient recurrent laryngeal nerve injury was significantly greater in Group B than in Group A (p = 0.019). Conclusions. Both Harmonic Focus and Thunderbeat Open Fine Jaw have proven to be effective devices. Operative times were significantly shorter in thyroidectomies performed with Thunderbeat Open Fine Jaw; however, the occurrence of transient recurrent laryngeal nerve injury was significantly greater in patients operated on with this device.

Can thyroidectomy be considered safe in obese patients? A retrospective cohort study

BACKGROUND

Obesity is a growing public health concern in most western countries. More and more patients with high body mass index (BMI) are undergoing surgical procedures of all kinds and, in this context, obese patients are undergoing thyroid surgery more than ever before. The aim of the present study was to evaluate whether thyroidectomy can be considered safe in obese patients.

METHODS

Patients undergoing thyroidectomy in our Unit between January 2014 and December 2018 were retrospectively analysed. Patients were divided into two groups: those with BMI < 30 kg/m² were included in Group A, while those with BMI ≥ 30 kg/m² in Group B. Univariate analysis was performed to compare these two groups. Moreover, multivariate analyses were performed to evaluate whether the BMI value (considered in this case as a continuous variable) had a significant role in the development of each individual postoperative complication.

RESULTS

A total of 813 patients were included in this study: 31 (3.81%) were underweight, 361 (44.40%) normal-weight, 286 (35.18%) overweight, 94 (11.57%) obese and 41 (5.04%) morbidly obese. Six hundred and seventy-eight patients were included in Group A and 135 in Group B. At univariate analysis, the comparison between the two groups, in terms of operative time and thyroid weight resulted in statistically significant results (P = 0.001, P = 0.008; respectively). These features were significantly higher in Group B than in Group A. About postoperative stay and complications, no statistically significant difference was found between the two groups. At multivariate analyses, only the development of cervical haematoma was statistically significantly correlated to the BMI value. Patients with high BMI had a lower risk of cervical haematoma (P = 0.045, OR 0.797, 95% CI 0.638-0.995).

CONCLUSIONS

This study showed that obesity, in the field of thyroid surgery, is not associated with any increase of postoperative complications. Thus, it is possible to conclude that thyroidectomy can be performed safely in obese patients. Our result about operative times had no clinical significance.

Combined tracheostomy and thyroidectomy in a patient with cervical spine fracture

Background

Combined tracheostomy and thyroidectomy is usually done in case of removal of a large goiter causing damage to the tracheal wall. Thyroidectomy to get access to the trachea for surgical airway is a rare procedure. Tracheostomy following cervical spinal fracture is challenging as no hyperextension can be provided limiting exposure.

Case report

A 45-year-old intoxicated male with a head on bicycle accident suffered a C1 fracture and cervical spinal shock requiring emergent intubation. The C1 fracture was managed with a cervical collar. The patient improved neurologically on the ICU; however, he could not be weaned from mechanical ventilation thus requiring tracheostomy. On initial trauma CT-scan, a large goiter displacing the trachea to the left side was seen. He was kept in line stabilized using towels in the OR. A 5 cm transverse neck incision was made. The large partially retrosternal goiter reaching the aortic arch was stepwise mobilized out of the neck. The isthmus was divided; the enlarged right lobe was brought out of the neck and resected. The trachea was pulled to the midline, crosswise incised, the skin flaps were sutured down and a 7 Shiley cannula was inserted. A PEG tube was placed. The patient had a protracted course but ultimately was transferred alert and oriented to a long-term rehabilitation facility moving all extremities.

Conclusion

Combined thyroidectomy with tracheostomy in the setting of cervical fracture is technically challenging but was an essential step in the recovery of this patient.
