Clinicopathologic characteristics and treatment of medullary thyroid carcinoma / 中华内分泌外科杂志

Objective To explore the clinicopathologic characteristics and treatment of medullary thyroid carcinoma(MTC).Methods The data of 42 cases of MTC admitted to Fujian Medical University Provincial Clinical College from Jan 1995 to Feb 2010 were retrospectively analyzed.Surgery was performed in all the 42 cases.All were proved to be MTC by pathology.Results Surgery was performed in all the 42 cases.All were proved to be MTC by pathology.The lymph node metastasis rate was 76.19％ (32/42).The central lymph node metastasis rate was 61.90％ (26/42).All the 42 cases were followed up for 1 to 502 months with 102 months as the median.35 cases(83.33％)were followed up for more than 5 years and the 5-year overall survival rate was 85.71％ (30/35).Death occurred in 5 cases.Conclusions The lymph node metastasis rate of MTC is high.The treatment should be based on the principle of radical resection.Total thyroidectomy should be recommended to treat primary tumor.Lymph node dissection should be as thorough as possible.Central compartment neck dissection should be done in all cases.

Galectin-3 in differential diagnosis between benign and malignant thyroid follicular tumor / 中华内分泌外科杂志

Objective To analyze the expression of Galectin-3 in thyroid follicular tumors and its clinical significance in differential diagnosis between benign and malignant thyroid follicular tumor.Methods The expression of Galectin-3 in 120 cases of thyroid follicular carcinoma and 80 cases of thyroid follicular adenoma was detected by immunohistochemical technique.Results The expression rate of Galectin-3 in thyroid follicular carcinoma was significantly higher than that in follicular adenoma(84％ vs 19％,P ＜ 0.01).Strong positive expression of Galectin-3 was found in 40％ cases of thyroid follicular carcinoma and no case of thyroid follicular adenoma.Conclusions The expression of Galectin-3 can be regarded as an important parameter for differential diagnosis between benign and malignant thyroid follicular tumor.

The diagnosis and treatment strategy of pancreatic injury / 中华内分泌外科杂志

Objective To summarize the experience of diagnosis and treatment strategy of pancreatic injury.Methods The data of 36 cases of pancreatic injurics admitted to Fujian Medical University Provincial Clinical College from 1990 to 2011 were analyzed retrospectively.Results 14 cases(39％)were diagnosed preoperatively,and the other cases were diagnosed during the laparotomy.2 cases underwent non-surgical treatment.34 cases underwent surgical treatment,among whom 23 cases underwent pancreatic debridement and drainage,6 cases underwent distal pancreatectomy(4 cases undergoing distal pancreatectomy plus splenectomy included),4 cases underwent distal Roux-Y pancreajejunostomy plus proximal pancreas closure,and 1 case underwent pancreatoduodenectomy.31 cases (86％) were cured,and 5 cases died (14％).Conclusions Most of the pancreatic injury is diagnosed through laparotomy.Surgical opcration is the main approach to treat pancreatic injury.Nonsurgical treatment is primarily limited to grade Ⅰ and Ⅱ pancreatic injury without obvious peritonitis,major pancreatic duct injury,and associated injuries.Surgical procedure should be selected based on the grading scale of pancreatic injury,associated injuries and overall conditions of the patient.

Clinical characteristics and surgical treatment of pancreatic duct stone / 中华内分泌外科杂志

Objective To explore clinical characteristics and surgical treatment of pancreatic duct stone.Methods Clinical data of 25 cases pancreatic duct stone undergoing operation from 1990 to 2008 were retrospectively analyzed. Results All of the 25 cases suffered upper abdominal pain, among whom 8 cases were concomitant with type 2 diabetes mellitus, 5 with steatorrhea, 2 with obstructive jaundice, 1 with pancreatic head cancer and 6 with acute pancreatitis recurrence history. All cases were confirmed by imaging diagnosis, such as ultrasonography, abdominal X-ray film, CT, endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography. 20 cases underwent pancreolithotomy with Roux-en-Y side-to-side pancreaticojejunostomy. 4 cases underwent body-tail pancreatectomy with pancreatojejunostomy and 1 case underwent pancreatoduodenectomy. No complication was found. 25 cases were followed for 2 months to 4 years after operation. Among all 25 cases with upper abdominal pain, 20 cases got rid of the symptoms and 5 cases were relieved postoperatively.Among 8 cases with diabetes mellitus, 4 cases resumed normal blood glucose postoperatively. Among 5 cases with steatorrhea, steatorrhea disappeared in 2 cases and 1 case were alleviated postoperatively. Conclusions Imaging examinations are the main diagnostic methods for pancreatic duct stone. Pancreolithotomy and Roux-en-Y side-toside pancreaticojejunostomy are effective operative techniques.

Preoperative localization in primary hyperparathyroidism / 中华内分泌代谢杂志

Retrospective analysis was performed on the preoperative imaging examinations in 18 patients with primary hyperparathyroidism (PHPT). The results showed that non-invasive imaging examinations such as B ultrasound, CT, MRI and ~(99m)Tc-MIBI radionuclide scanning were of great value in locating the lesions of PHPT, ~(99m)Tc-MIBI radionuclide scanning is recommended as the method of first choice.
