Background:
Thyroid Natural Orifice Transluminal Endoscopic Surgery (NOTES) or transoral endoscopic thyroidectomy using vestibular approach is a recent advance embraced by the surgical community because of its potential for a scar-free thyroidectomy. In this article, we present our initial experience with this technique.
Materials and Methods:
We used a three-port technique through the oral vestibule, one 10 mm port for the laparoscope and two additional 5 mm ports for the endoscopic instruments required. The carbon dioxide insufflation pressure was set at 12 mm of Hg. Anterior cervical subplatysmal space was created from the oral vestibule down to the sternal notch, and the thyroidectomy was done using conventional laparoscopic instruments and a harmonic scalpel.
Results:
From May 2016 to December 2017, we have performed ten such procedures in the Department of General Surgery in our hospital, which is a tertiary referral center. Six patients had solitary thyroid nodules, for which a hemi-thyroidectomy was done. Four patients had multi-nodular goiter and total thyroidectomy or near-total thyroidectomy was done. The preoperative fine-needle aspiration cytology (FNAC) was suggestive of Bethesda class 2 lesions in all the patients with multinodular goiter and in five of the six patients with solitary nodular goiter. Only one patient with solitary nodular goiter had a Bethesda class 3 lesion on FNAC. The final histopathological report of the specimen was benign, either colloid goiter, or degenerative nodule in all cases of multinodular goiter and in four cases of solitary thyroid nodule. In one Bethesda class 2 solitary nodule, the histopathological report was suggestive of follicular carcinoma; in the Bethesda class 3 solitary nodule, the histopathological report was suggestive of follicular variant of papillary carcinoma. No complication such as temporary or permanent vocal cord paralysis, hypoparathyroidism, subcutaneous emphysema, pneumomediastinum, tracheal injury, esophageal injury, mental nerve palsy, or surgical site infection was found postoperatively. However, two patients developed small hematomas in the midline.
Conclusion:
Transoral endoscopic thyroidectomy is a safe, feasible, and minimally invasive technique with excellent cosmetic results.
Primary splenic angiosarcomas (PSA) arise from splenic endothelium are rare and impose a diagnostic challenge preoperative. They can present as asymptomatic splenomegaly however; the commonest presentation is abdominal pain. The spleen can rapidly increase in size and can manifest as spontaneous rupture which would cause peritoneal dissemination of disease. Early metastasis of PSA is seen in liver, lungs, lymph nodes and gastrointestinal system. Preoperative diagnosis requires a high index of suspicion and ultrasound, contrast enhanced computerized tomography may essential to differentiate from splenic hemangioma. Splenic angiosarcoma are best treated with splenectomy with a limited disease, with care taken not to rupture and cause spillage. PSA are resistant to adjuvant radiation and chemotherapy. Mortality is high with median survival rate of only 5 months, irrespective of treatment and hence the need to diagnose before complications. Bisphosphonates, adjuvant radiation with chemotherapy have been attempted to increase disease free survival. We report a case of PSA emphasizes on early preoperative diagnosis to avoid progression of the disease.
