Medial Approach for Identification of Recurrent Laryngeal Nerve in Locally Advanced Differentiated Thyroid Carcinoma: Revisited.

Recurrent laryngeal nerve injury is a well-recognized and potentially catastrophic complication of thyroidectomy. In literature, four approaches have been described for identification of RLN, the superior, lateral, medial, and inferior approaches. But medial approach is lesser known amongst surgeons. Locally infiltrative thyroid cancer with extensive lymph nodal metastasis in central and lateral compartment sometimes makes it difficult to identify RLN by any of these standard approaches described above. A medial approach was described where RLN is identified as it extends up to interdigitate with the trunk or the branches of the inferior thyroid artery. We present here a new alternative technique for identification of recurrent laryngeal nerve through modified medial approach that was used in difficult thyroidectomies.

Papillary thyroid carcinoma with nodular fasciitis-like stroma: a rare variant.

Papillary thyroid carcinoma with desmoid-type fibromatosis (PTC-DTF) or nodular fasciitis-like stroma (PTC-NFS) is a rare morphological variant of PTC with a favorable prognosis. There is a paucity of molecular data regarding this entity. We present the case of a 20-year-old female who presented with a palpable mass over the anterior aspect of the neck for the past 3-4 months, which was diagnosed as PTC-NFS. Ultrasonogram of the neck revealed a bulky left lobe of thyroid that contained a well-defined heterogenous lesion measuring around 24 × 26 × 36 mm with involvement of the adjacent isthmus. She underwent a total thyroidectomy with central compartment lymph node dissection. Histological examination revealed a biphasic tumor with epithelial and stromal components resembling nodular fasciitis. Two dissected lymph nodes showed metastasis of the epithelial component only. On immunohistochemistry, BRAF mutant protein expression was evident in the epithelial component only, while ß-catenin was negative in both the components. The histopathological diagnosis of papillary thyroid carcinoma with nodular fasciitis-like stroma was offered. Sanger sequencing revealed a BRAFV600E (c.1799T>A, Val600Glu) mutation. Post-operatively, no residual tumor was detected on ultrasound and radioiodine scans. The patient was doing well at follow-up of 9 months. PTC-NFS/DTF is a histological variant of PTC with a favorable prognosis. Our index case was associated with the BRAF mutation, which was restricted to the epithelial component. Thorough sampling of the excised specimen is essential in order not to miss the epithelial component, which, in most reported cases (including ours) appears to be small.

Short Stay Thyroid Surgery: Can We Replicate the Same in Low Resource Setting?

INTRODUCTION: The concept of short stay thyroidectomy has been tested and in practice in the developed world; the same has not been replicated in countries with limited resources due to lack of organized healthcare system. So, in this study, we tried to analyze if short stay thyroid surgery can be performed in a cost-effective way in developing countries and also if the endocrine surgical trainee can deliver these services safely. METHODS: The study was conducted prospectively from January 2013 to July 2014, at Department of Endocrine Surgery, SGPGIMS, Lucknow, India. Study group included patients undergoing short stay hemithyroidectomy whereas matched patients who qualified for inclusion criteria but did not undergo short stay surgery due to various reasons constituted control group. Outcome in both the groups was compared in terms of complication rates, cost benefit, and patient satisfaction. Subgroup analysis was also done for trainee versus consultant performed short stay thyroid surgery. RESULTS: A total of 439 patients with surgical thyroid disorders were evaluated at our institute during the study period and out of these 110 patients (58 cases and 52 controls) fulfilled the inclusion criteria. Younger patients with low socioeconomic status who were paying out of pocket were found to be more inclined to short stay thyroid surgery. There was no significant difference between the two groups in terms of postanesthetic discharge score (PADS), complication rates, and patients satisfaction; however there was significant reduction (p <0.001) in hospital cost in short stay group. In subgroup analysis, procedure time was more in trainee performed surgeries; however there was no significant difference in terms of mean PADS and complication rates. CONCLUSION: Short stay thyroidectomy can provide a better cost-effective alternative to conventional thyroidectomy in patients undergoing thyroid surgery and can be safely performed by endocrine surgical trainees even in a low resource setting.
