Predictive value of thyroid tissue density in determining the patients on whom sternotomy should be performed.

BACKGROUND: Retrosternal goiter incidence rates range between 0.2% and 45% of all goiters, and sternotomy is performed in some of patients. There is no consensus for selecting the patients on whom sternotomy should be performed. We aimed to determine the most important factor for predicting requirement of sternotomy. METHODS: This prospective study included 260 patients with retrosternal goiter. The clinical symptoms, history of previous thyroidectomy, presence of tracheal deviation, tracheal compression, site of mediastinal extension, thyroid tissue density, findings of intubation, type of surgical approach, histologic findings of thyroid, weight of thyroid, and postoperative complications were evaluated. RESULTS: Thyroid tissue density, posterior location, and subcarinal extension were found to be independent factors for predicting requirement of sternotomy. The risk for sternotomy increased 47-fold for patients with harder thyroid tissue density (OR: 47.3; 95% CI: 5.8-385.70), 20-fold for patients with subcarinal extension (OR: 20.5; 95% CI: 2.5-168), and 10-fold for patients with posterior location (OR: 10.5; 95% CI:1.8-60). CONCLUSION: Thyroid tissue density was defined the strongest predictive factor for requirement of sternotomy. Preoperatively obtained information thyroid tissue density can be useful for surgical strategy.

Single incision laparoscopic pancreas resection for pancreatic metastasis of renal cell carcinoma.

BACKGROUND: Transumbilical single incision laparoscopic surgery (SILS) offers excellent cosmetic results and may be associated with decreased postoperative pain, reduced need for analgesia, and thus accelerated recovery. Herein, we report the first transumbilical single incision laparoscopic pancreatectomy case in a patient who had renal cell cancer metastasis on her pancreatic corpus and tail. METHODS: A 59-year-old female who had metastatic lesions on her pancreas underwent laparoscopic subtotal pancreatectomy through a 2-cm umbilical incision. RESULTS: Single incision pancreatectomy was performed with a special port (SILS port) and articulated equipment. The procedure lasted 330 minutes. Estimated blood loss was 100mL. No perioperative complications occurred. The patient was discharged on the seventh postoperative day with a low-volume (20mL/day) pancreatic fistula that ceased spontaneously. Pathology result of the specimen was renal cell cancer metastases. CONCLUSION: This is the first reported SILS pancreatectomy case, demonstrating that even advanced surgical procedures can be performed using the SILS technique in well-experienced centers. Transumbilical single incision laparoscopic pancreatectomy is feasible and can be performed safely in experienced centers. SILS may improve cosmetic results and allow accelerated recovery for patients even with malignancy requiring advanced laparoscopic interventions.

Minimally invasive video-assisted subtotal parathyroidectomy with thymectomy for secondary hyperparathyroidism.

BACKGROUND: Secondary hyperparathyroidism (sHPT) is common in patients with chronic renal failure. Bilateral cervical exploration is optimal for patients with sHPT. The aims of this clinical trial are to evaluate the feasibility of video-assisted subtotal parathyroidectomy as an alternative surgical treatment for sHPT. METHODS: This prospective study included 12 consecutive patients with sHPT. Surgical indications included a high intact parathormone level, enlarged parathyroid glands, high bone turnover and conditions refractory to medical treatment of hypercalcemia and hyperphosphatemia. RESULTS: All patients underwent minimally invasive video-assisted subtotal parathyroidectomy and trans-cervical thymectomy. Four cervical glands were found in all patients and intrathymic glands were identified in three (25%) patients. CONCLUSION: Minimally invasive video-assisted subtotal parathyroidectomy offers an alternative method, and this technique can be performed safely for sHPT.
