- Practical tips to reduce complication rate in thyroidectomy(2017) CERNEA, Claudio; BRANDAO, Lenine G.; HOJAIJ, Flavio C.; CARLUCCI, Dorival De; VANDERLEI, Felipe; GOTODA, Renato; LEITE, Ana K.; KULCSAR, Marco A. V.; MATOS, Leandro L.; DEDIVITIS, Rogerio A.; ARAUJO-FILHO, Vergilius J. F.; TAVARES, Marcos R.Introduction: Thyroid cancer is the most frequent endocrine neoplasm, and its incidence has been consistently rising during the last decades. Surgical treatment is the choice, but the complications can be truly devastating. Methods: The objective of this article is to present some practical tips to reduce the complication rate in thyroid surgery. Results: The more frequent complications during a thyroidectomy are mentioned, as well as practical tips to try to prevent them: acute airway compression, nerve injuries (both inferior laryngeal and external branch of the superior laryngeal nerves), and hypoparathyroidism. Conclusion: The prevention of complications during a thyroidectomy is imperative. The only way that the surgeon can assure the safety is to strictly adhere to technical principles, with diligent hemostasis, thorough anatomical knowledge, and gentle handling of the anatomic structures adjacent to the thyroid gland.
- Abdominal compression: A new intraoperative maneuver to detect chyle fistulas during left neck dissections that include level IV(2012) CERNEA, Claudio R.; HOJAIJ, Flavio C.; CARLUCCI JR., Dorival De; TAVARES, Marcos R.; ARAUJO-FILHO, Vergilius J.; SILVA-FILHO, Gilberto Britto e; BRANDAO, Lenine G.Background Chyle fistulas may occur after left neck dissections that include level IV, due to injury of the thoracic duct or of 1 of its major branches. Despite being unusual, this complication carries substantial postoperative morbidity and even mortality. So far, no effective intraoperative maneuver has been reported to detect this fistula at the end of a neck dissection. In this cohort study, we sought to describe a simple new maneuver, intraoperative abdominal compression, which can effectively help to identify an open major lymphatic duct on level IV at the end of a neck dissection. Patients and Methods From March 1989 to September 2010, 206 patients underwent neck dissections involving left level IV, and underwent intraoperative abdominal compression. There were 119 men and 87 women, with ages ranging from 18 to 81 years (median, 52 years). One hundred forty-four patients had squamous cell carcinomas, 54 had thyroid carcinomas, 5 had malignant melanomas, and 3 had salivary cancers. Distribution by type of left neck dissection was: selective including levels II, III, and IV (73 cases; 35.4%), selective including levels II, III, IV, and V (55 cases; 26.6%), selective including levels I, II, III, and IV (12 cases; 5.8%), modified radical (47 cases; 22.8%), and radical (19 cases; 9.2%). In all cases, at the end of the procedure, the endotracheal tube was temporarily disconnected from the ventilator. Keeping the dissected level IV area under clear visualization, an abdominal compression was performed. At this moment, any detected lymphatic leak was carefully clamped and tied with nonabsorbable sutures. After ventilating the patient, the intraoperative abdominal compression was repeated to reassure complete occlusion of the lymphatic vessel. Results In 13 cases (6.3%), a chyle leak was detected after performing the intraoperative abdominal compression. All leaks except for 2 were successfully controlled after 1 attempt. In these 2 patients, a patch of muscle and fat tissue was applied with fibrin glue on the top. In 1 of these patients, another chyle leak in a different location was detected only at the second intraoperative abdominal compression, and was also effectively closed. Postoperatively, there were 2 (1%) chyle fistulas, both among these 13 cases, and all were successfully managed with clinical measures only. No fistulas occurred among the remaining 193 patients in whom intraoperative abdominal compression did not demonstrate lymphatic leak. Conclusion To our knowledge, this is the first description of a specific maneuver to actively detect a lymphatic fistula at the end of a left neck dissection involving level IV. In this study, intraoperative abdominal compression was able to detect an open lymphatic vessel in 6.3% of the cases, as well as to assure its effective sealing in the remaining 93.7% of the patients. Moreover, no life-threatening high-volume fistula was noted in this study. (C) 2012 Wiley Periodicals, Inc. Head Neck, 2012
