Objective To detect the influence of the first operation standardized or not on reoperation for differentiated thyroid carcinoma.Methods Retrospective analysis was conducted of the clinical data of 217 reoperation case of differentiated thyroid carcinoma from May 2009 to March 2018 in the 960th Hospital of the PLA Joint Logistic Support Force,including 58 male cases and 159 female cases,with the average age of 46.65 years (range from 19 to 76).According to the first operation standardized or not,all patientswas divided into standardized group (n =114) and non-standard group (n =103).Between the two groups,the number of dissected and metastatic lymph nodes,tumor pathology,recurrence range of glandular and central lymph nodes,number of lymph nodes removed and transferred,operation and drainage time,tumor invaded surrounding tissues,invasion sites,and complications were conducted.Results The overall gland recurrence rate was 20.2％ of 217 cases (44/217),8.8％ (10/114) in the standardized group and 33％ (34/103)in the non-standard group.The central group had a total recurrence rate of 38.7％ (84/217),and the standardized group and non-standard group were 22.8％ (26/114) and 56.3 ％ (58/103),respectively.For patients,the total cervical lymph node recurrence rate was 74.7％ (162/217),and the standardized group and non-standard group were 87.7％ (100/114),and 60.3％ (62/103),respectively.All of the difference was statistically significant(P =0.000,P =0.000,P =0.000).The operation time and drainage time of the standardized surgery group were significantly shorter than the non-standard group[(2.52±0.80)h vs(3.14±0.83) h,P=0.000;(4.37±1.28)d vs (5.16±1.41)d,P=0.000].Conclusions For differentiated thyroid carcinoma,the nonstandard treatment significantly affected the tumor residual rate in gland and lymph node metastasis rate of reoperation,andstandardized surgical treatmentshould be advocated.

Objective To summarize the clinical data of the children with inflammatory bowel diseases (IBD),including Crohn's disease (CD) and ulcerative colitis (UC),and to analyze and compare the clinical features of very early-onset IBD (VEO-IBD) and late-onset IBD (LO-IBD).Methods A retrospective analysis of the clinical data of 184 cases of IBD hospitalized children diagnosed at Beijing Children's Hospital,Capital Medical University from January 2000 to December 2014.According to their ages of onset,the patients were divided into VEO-IBD group (＜6 years old) and LO-IBD group (6-16 years old);the patients with CD were divided into VEO-CD group (＜ 6 years old) and LO-CD group (6-16 years old);UC were divided into VEO-UC group (＜ 6 years old) and LO-UC group (6-16 years old).The clinical features among each group were analyzed and compared.Results A total of 184 IBD patients were included in the study,77 cases(41.8％) were VEO-IBD and 107 cases(58.2％) were LO-IBD.Comparison between VEO-CD group and LO-CD group indicated that abdominal pain was more common in LO-CD group (P ＜ 0.05),while diarrhea and hematochezia were more common in VEO-CD group (all P ＜ 0.05).In addition,comparison between VEO-UC group and LO-UC group indicated that abdominal pain was more common in LO-UC group(P ＜ 0.001),while diarrhea,fever,and oral ulcers were more common in VEO-UC group (all P ＜0.05).Both VEO-CD and LO-CD group were mainly ileocolonic[15/27 cases (55.6％),20/47 cases (42.6％)],non-narrow,non-penetrating [20/27 cases (74.1％),30/47 cases (63.8％)] and moderate-to-severe activity[23/27 cases(85.2％),37/47 cases (78.7％)].The incidence of perianal lesions in the VEO-CD group was as high as 51.9％ (14/27 cases),which was significantly higher than that in the LO-CD group (9/47 cases,19.1％) (P ＜ 0.05).Left-sided UC and severe UC were more common in VEO-UC group(all P ＜ 0.05),while pancolitis and mild UC were more common in LO-UC group (all P ＜ 0.05).The incidence of intestinal perforation in the VEO-UC group was significantly higher than that in the LO-UC group (P ＜0.05).The incidence of surgical rate,intestinal obstruction,and intestinal perforation in the LO-CD group were significantly higher than those in the LO-UC group (all P ＜ 0.05).Conclusions Compared between VEO-IBD and LO-IBD,VEO-IBD patients are more severe,with perianal lesions more common,and the incidence of intestinal perforation is higher.

Objective: To investigate the surgical treatment strategies for persistent and recurrent parathyroidectomy after total parathyroidectomy plus autotransplantation(tPTX+ AT) in cases of renal hyperparathyroidism. Methods: From Oct 2009 to Oct 2018, 480 patients with renal hyperparathyroidism received tPTX+ AT in our hospital. 32 patients suffered from post-op persistent (31) and recurrent (1) hyperparathyroidism .The high frequency ultrasonography combined with fine needle puncture eluent PTH determination and SPECT/CT co-computed tomography fusion imaging were used as qualitative and localizing diagnostic methods before reoperation. Results: Of the 32 patients, 28 cases underwent reoperation for once, and 4 underwent reoperations fort wice. 36 parathyroid glands and 2 grafts were resected.In 31 patients the bone pain, skin pruritus relieved significantly or disappeared, and muscle strength gradually increased compared with that before operation. Level of iPTH in 31 patients fluctuated between 15 and 90 ng/L. Postoperative parathyroid hormone decreased compared with that before the operation (P<0.05). One patient was still with persistent hyperparathyroidism despite reoperation, whose iPTH fluctuated between 550 and 1 000 ng/L during 6 months to 2 years follow-up. Conclusion Ultrasonography, FNA-iPTH and SPECT/CT co-computed tomography can be used as methods for qualitative and localizing diagnosis of PTPT or PHPT.With accurate preoperative localization, resection of all parathyroid glands is an effective treatment for posto perative persistent and recurrent renal hyper parathyroidism.

Objective To assess the safety and diagnostic accuracy of manual carbon dioxide (C02) digital angiography in performing endovascular therapy (EVT) for arteriosclerosis obliterans (ASO) of lower extremity in patients who have renal insufficiency or iodine allergy. Methods The clinical data of 19 patients with lower extremity ASO complicated by renal insufficiency or iodine allergy, who were admitted to authors' hospital to receive EVT of lower extremity with intraoperative C02 angiography during the period from January 2013 to March 2015, were retrospectively analyzed. Using manual bolus injection of C02, or with additional use of minimum dose of iodinated contrast media, CO2 angiography was performed so as to guide EVT procedure. The safety and diagnostic accuracy of manual C02 angiography were evaluated. Results A total of 21 endovascular treatments were performed in 19 patients with lower extremity ASO, and a total of 28 arterial segment lesions were treated. The technical success rate was 100％. Ankle-brachial index (ABI) was improved from preoperative 0. 56±0. 08 to postoperative 0. 74±0. 07, the difference was statistically significant (t= -20. 605, P＜0. 00l). The mean serum creatinine (sCr) levels tested at 48 h and one week after the treatment were (159. 91±33. 21) μmol/L and (143. 44±43. 59) μmol/L respectively, which were not significantly different from preoperative (139. 5±37. 6) μmol/L (t=-1. 098, P=0. 285), and none of these results met the standard of contrast nephropathy. Among the 21 times of EVT procedure, additional use of iodinated contrast media was employed in 13 procedures, the average used amount of iodine contrast agent was (12±5. 5) mL. After the treatment, sCr level was elevated, the estimated glomerular filtration rates (eGFR) were lower than 50 mL· min-1 · 1. 73 m-2, which restored to preoperative level in one week. CO2 angiography showed that the image quality of all arteries above the knee joint met the requirements of treatment, except for one patient whose images could not accurately display the length and extent of the stenosis due to restenosis of the superficial femoral artery. The image quality of the arteries below the knee level was usual. Conclusion In performing EVT procedure to treat lower extremity ASO the use of C02 angiography is safe. The image quality of all arteries above the knee joint is satisfactory, it can significantly reduce, or even avoid, the use of iodine contrast agents. Therefore, this technique is especially suitable for patients who have renal insufficiency or iodine allergy. (J Intervent Radiol, 2018, 27:211-214)

Objective To evaluate the clinical safety and effectiveness of total parathyroidectomy with autotransplantation on the chronic renal failure (CRF) patients who are suffering from severe secondary hyperparathyroidism (SHPT).Methods A retrospective analysis was performed on 149 patients with secondary hyperparathyroidism who were given total parathyroidectomy with autotransplantation from Apr.2010 to Oct.2015.The changes of clinical symptoms,parathyroid hormone,calcium and phosphate blood levels were followed up during 6 months to 6 years.Results 598 parathyroid glands were obtained form 149 patients who underwent surgical resection.Musculoskeletal pain and skin itching relieved or disappeared in 145 cases the 2nd day after operation,while these symptoms gradually relieved one week after operation for 4 cases.Serum intact parathyroid hormone (iPTH)was 89.67±180.61,serum phosphate 1.74±0.52,and serum calcium 2.07±0.32 the 1st day after operation,and they all decreased compared with those before operation(P＜0.001).Serum calcium,phosphorus and iPTH levels were similar at 6,36 and 60 months after operation (P＞0.05).Two patients had pathological fracture after operation.No persistent bone pain or skin itching was found during the follow-up period.Two patients had secondary hyperparathyroidism.Six patients had recurrence,among whom five underwent surgery again,and one patient had clinical follow-up.One patient died of pulmonary infection at 13 months after operation.Conclusion Total parathyroidectomy with autotransplantation were applied to ineffective medical treatment for advanced secondary hyperparathyroidism in patients with chronic renal failure.

Objective To evaluate the clinical safety and effectiveness of da Vinci Si surgical system in total parathyroidectomy with autotransplantation of secondary hyperparathyroidism.Methods A retrospective analysis was conducted with da Vinci Si surgical system on 16 patients with secondary hyperparathyroidism who were given total parathyroidectomy with autotransplantation from Mar 2014 to June 2016.The changes of clinical symptoms,parathyroid hormone,calcium and phosphate blood levels were followed up from 6 months to 2 years.Results Surgery was successful in all 16 cases and 62 parathyroid glands were resected.There were no operation-related complications and no conversions to open or endoscopic surgery.Mean operation time was (136 ± 24) minutes.In all postoperative cases the musculoskeletal pain,skin itching were relieved or disappeared.PTH,calcium and phosphate blood levels decreased and no recurrence during follow-up period,The postoperative cosmetic result was satisfatory.Conclusions Da Vinci Si surgical system used in the parathyroid surgery is safe and effective,especially suitable for patients with cosmetic requirements.

Tertiary hyperparathyroidism is commonly observed in patients with long-standing chronic kidney disease (CKD) after renal transplantation and is characterized by the autonomous hypersecretion of PTH leading to hypercalcemia.The primary treatment is surgery.After the introduction of cinacalcet,both surgical and medical methods have been commonly performed to treat tertiary hyperparathyroidism.However,which treatment is more appropriate has not been fully demonstrated.In this paper,the author will systematically review the related research of surgical treatment and cinacalcet in the treatment of 3HPT,and summarize their respective therapeutic effects.

Objective To explore the diagnostic value in fine needle aspiration cytology combined with thyroghobulin measurement of suspected malignant cervical enlarged lymph node in differentiated thyroid carcinoma.Methods The study included 82 patients with differentiated thyroid carcinoma who were found suspected metastatic lymph nodes in neck during follow-up and accepted reoperation from January 2015 to May 2017.Ultrasound-guided fine-needle aspiration was done in 130 suspected malignant lymph nodes,at the same time,thyroghobulin in fine needle aspiration cytology washout fliud was measured with electrochemiluminescence,fine needle aspiration cytology combined with thymglobulin measurement in fine-needle aspiration biopsy.All suspicious malignant lymph nodes were precise positioning preoperative by injection of mnocarbon suspension under guidence of ultrasound.The analyze was performed according to the final pathological diagnosis after operation.The sensitivity,specificity and accuracy of fine needle aspiration cytology,thymglobulin measurement in fine-needle aspiration biopsy,fine needle aspiration cytology and thyroglobulin measurement in fine-needle aspiration biopsy were calculated by Fomage's statistical method and x2 test was used for comparison among groups.Results Eighty-two patients with 130 lymph nodes with definitemarkers and pathological diagnosis,with a pathological examination of 119 and negative 11 cases.The sensitivity of fine needle aspiration cytology,thyroglobulin measurement in fine-needle aspiration biopsy,fine needle aspiration cytology and thyroglobulin measurement in fine-needle aspiration biopsy was 88.2％,94.1％ and 95.8％,with specificity of 54.5％,72.7％ and 81.8％,with accuracy of 85.4％,92.3％ and 94.6％.Conclusion The sensitivity,specificity and accuracy of fine needle aspiration cytology combined thyroglobulin measurement in fine-needle aspiration biopsy were higher than that of fine needle aspiration cytology or thyroglobulin measurement in fine-needle aspiration biopsy alone,which can be used as a method of qualitative diagnosis during differentiated thyroid cancer postoperative follow-up.

Objective To evaluate the safety and feasibility of INTRABEAM in breast conserving surgery for early stage breast cancer.Methods Clinical data of 43 cases of early breast cancer undergoing INTRA-BEAM intraopetative radiotherapy from Jan.2013 to Dec.2014 were retrospectively analyzed.All cases underwent breast conserving surgery combined with 20 Gy INTRABEAM intraoperative radiotherapy.The postoperative incision,incidence of local complications and acute radiation injury were recorded after surgery.Breast recovery,the cosmetic effects,early overall survival,recurrence-free survival,and non-metastatic survival were followed up.Results All cases were given breast conserving surgery associated with INTRABEAM intraoperative radiotherapy (20 Gy),with median radiotherapy time of 31 mins ranging from 25 to 39 mins.Five cases underwent postoperative whole breast irradiation.Major early complications included incision infection (1 case),postoperative effusion (5 cases),radiation area skin pain (4 cases).The short-term follow-up survey showed that the satisfaction rate was 93.0％.The overall survival rate,recurrence free survival rate and metastasis free survival rate was 100％ respec tively.Conclusion Breast conseving surgery combined with INTRABEAM intraoperative radiotherapy for early breast cancer patients is safe and feasible.

OBJECTIVETo evaluate surgical outcomes and the feasibility of robotic thyroidectomy and central neck dissection (CND).

METHODSThe clinical data of 40 patients of papillary thyroid microcarcinoma underwent total thyroidectomy (or lobectomy and isthmusectomy) and CND using the Da Vinci system through axillo-bilateral-breast approach in Jinan Military General Hospital of People's Liberation Army from February to December 2014 were analyzed retrospectively (robotic group). Other forty patients of papillary thyroid microcarcinoma underwent total thyroidectomy (or lobectomy and isthmusectomy) and CND by open approach were selected as the control (open group). Cosmetic satisfaction was assessed after a month postoperation by the numerical score system. t-test and χ(2) test were used to compare the clinical characters, total operative time, intraoperative estimated blood loss, postoperative hospital stay, number of lymph nodes removed, visual analogue scale for pain, postoperative complications, and cosmetic effect between the 2 groups.

RESULTSAll 80 patients were diagnosed of papillary thyroid microcarcinoma. The total thyroidectomy (or lobectomy/isthmusectomy) with CND of 40 patients were successfully performed by da Vinci Si surgical system. The numbers of total thyroidectomy of robotic group and the open group were 36 and 37, respectively. The numbers of metastatic lymph nodes of robotic group and open group were 14 and 15, respectively. The operation time of the robotic group was (130±12) minutes, which was longer than that of open group (98±11) minutes (t=12.432, P<0.05). The study showed statistical significant difference between the two groups regarding the visual analog scale pain assessment (1.9±0.9 vs.3.9±1.1, t=8.900, P<0.05). There were no statistical significant difference of intraoperative estimated blood loss, postoperative hospital stay, number of lymph nodes removed, and the complication rate between the 2 groups.Postoperative cosmetic result was more satisfying on the robotic group (9.1±0.5) than open group (4.8±1.5) (t=17.200, P<0.05).

CONCLUSIONSThe robotic total thyroidectomy (or lobectomy and isthmusectomy) and CND has similar surgery safety and feasibility as open procedures. The robotic thyroidectomy is a good alternative surgical modality for patients with papillary thyroid microcarcinoma who wish to avoid neck scars.
