Objective To investigate the expression of chemokine receptor CXCR7 and the relation between its expression and clinicopathologic characteristics in papillary thyroid carcinoma. Method The expressions of CXCR7 in 79 cases of papillary thyroid carcinoma and their paracancerous tissues，and 33 cases of benign thyroid lesion tissues were detected by immunohistochemistry. Results The positive expression rates of CXCR7 were 0（0/79），65.8%（52/79），and 30.3%（10/33） in the paracancerous tissues，papillary thyroid carcinoma tissues，and benign thyroid lesions tissues，respectively. The positive expression rate of CXCR7 in the papillary thyroid carcinoma tissues was significantly higher than that in the paracancerous tissues （P＜0.05） or benign thyroid lesion tissues（P＜0.05）. The expression of CXCR7 was correlated with lymph node metastasis （P＜0.05）. Conclusion CXCR7 might take part in tumorigenesis，progression，and lymph node metastasis of papillary thyroid carcinoma.
ObjectiveTo discuss application of " counter clockwise resection” in total laparoscopic pan-creaticoduodenectomy (TLPD) and summarize it’s preliminary experiences.MethodThe clinical data of consecutive 8 patients underwent TLPD in the Department of Pancreatic Surgery, Affiliated Shengjing Hospital of China Medical University from July 2016 to January 2017 were analyzed retrospectively.ResultsThere were 3 males and 5 females in these 8 patients. The age was (64.13±15.01) years. The results of postoperative pathology included 1 duodenal cancer, 2 distal biliary tract cancers, 4 pancreatic head cancers, and 1 solid pseudopapillary tumor of pancreatic head. All the 8 patients were performed with TLPD successfully, and the time of the operation was (527.50±69.44) min, the resection time of the specimen was (241.25±38.71) min, and the blood loss was (368.75±162.43) mL, the postoperative hospitalization stay was (18.67±4.00) d. There were no postoperative bleeding, perioperative death, and delayed gastric emptying．Four patients suffered from the pancreatic fistula including 3 cases of grade A and 1 case of grade B pancreatic fistulas, and 1 case suffered from the intra-abdominal infection, who were cured after the conservative treatment. All the patients were following-up, and there was no abnormality.ConclusionPreliminary results of limited cases in this study show that " counter clockwise resection” might be a safe, effective, and easy method of TLPD, but further research is need to study.
Objective To summarize preliminary experience of laparoscopic pancreaticoduodenectomy for periampullary carcinoma. Method The clinical data of patients with periampullary carcinoma underwent laparoscopic pancreaticoduodenectomy from July 2016 to September 2016 in the Shengjing Hospital of China Medical University were analyzed retrospectively. Results Two patients underwent complete laparoscopic pancreaticoduodenectomy, 2 patients underwent laparoscopic resection and anastomosis assisted with small incision open. The R0 resection and duct to mucosa pancreaticojejunal anastomosis were performed in all the patients. The operative time was 510–600 min, intraoperative blood loss was 400–600 mL, postoperative hospitalization time was 15–21d, postoperative ambulation time was 6–7 d. Three cases of pancreatic fistula were grade A and all were cured by conservation. No postoperative bleeding, delayed gastric emptying, intra-abdominal infection, and bile leakage occurred. The postoperative pathological results showed that there was 1 case of pancreatic head ductal adenocarcinoma, 1 case of cyst adenocarcinoma of pancreas uncinate process, 1 case of papillary carcinoma of duodenum, and 1 case of terminal bile duct carcinoma. Conclusion The preliminary results of limited cases in this study show that laparoscopic pancreaticoduodenectomy has been proven to be a safe procedure, it could reduce perioperative cardiopulmonary complications, its exhaust time, feeding time, and postoperative ambulation time are shorter, but its operative complications could not be reduced.
