RESUMO
Objective:To analyze the clinical outcome and feasibility for patients who underwent total parathyroidectomy without autotransplantation (TPTX) for secondary hyperparathyroidism (SHPT).Methods:From April 2012 to December 2015,220 SHPT patients underwent TPTX in the department of Breast and Thyroid Surgery of China-Japan Friendship Hospital.The clinical data and effect were assessed retrospectively.Results:All the 220 patients were on permanent dialysis with mean duration of dialysis (7.93 ± 3.75) years.A durable reduction in mean PTH,Ca and P were observed after TPTX (P<0.01).The mean hospital stay was (7.8 ± 2.8) days.TPTX produced a rapid improvement in clinical symptoms.Incidence of hypocalcemia was 73.46%.Severe complications such as recurrent laryngeal nerve palsy or inactive dynamic osteopathia,haven't been observed postoperatively.The rate of persistent status (PTH≥300 pg/mL) was 9.1%.One (0.45%) died of infectious shock perioperatively.Conclusions:TPTX was a safe and feasible surgical procedure for patients with SHPT.It was worth of being applied.Not missing the parathyroid during operation was the key point for successful TPTX.Intensive monitoring and maintaining stable normocalcemia were the key point to reduce complication.
RESUMO
Objective To investigate the short?term complications and cosmetic outcomes of radiotherapy in breast conserving surgery for early?stage breast cancer. Methods A retrospective analysis was performed on clinical data from 30 patients with early?stage breast cancer from 2013 to 2015. All patients underwent breast conserving surgery combined with intraoperative low?energy X?ray radiotherapy. The prescribed dose was 20 Gy at the surface of the applicator. Local complications, radiation injury, and cosmetic outcomes were observed after surgery. Results No grade 3?4 adverse reactions were found in patients. In terms of short?term complications, four patients (13%) had seroma, two of whom needed suction treatment;three patients ( 10%) had grade 1?2 skin erythema. Half of the patients had excellent cosmetic outcomes. None of the patients had local recurrence or distant metastasis. Conclusions Intraoperative low?energy X?ray radiotherapy is safe and feasible in breast conserving surgery for breast cancer. It can be considered as an optional approach for tumor bed boost in some patients with early?stage low?risk breast cancer.
RESUMO
The recent development and wide application of ultrasonography and ultrasonography-guided fine needle aspiration biopsy have greatly facilitated the detection of papillary thyroid microcarcinoma (PTMC).Currently, the occurrence, development and pathological features of PTMC are not clearly understood.Therefore, no consensus on the diagnosis and treatment has been reached.Patients with PTMC are suggested to be closely observed and periodically examined with ultrasonography in some countries such as Japan, and these patients are to be operated when the tumor enlarged or new lymphatic metastasis are found.Operation is the first choice in the European and American countries, and the long-term survival rates of these patients are nearly 100%.For the PTMC patients with the risk factors such as thyroid capsule invasion, lymphatic metastasis,multi-focal lesion, higher degree of malignancy, thyroid stimulating hormone suppression therapy was given after operation, which may reduce the local recurrence rate.In China, we should hold well thelimitation and choose the best way for different patients according to the personalized principle in clinical practice.
RESUMO
Objective To analyze clinicopathologic features and treatment strategy of postsurgical incidental papillary thyroid microcarcinoma(PTMC).Methods A total of 305 patients undergoing surgery for thyroid diseases from Apr.2012 to Mar.2013 were retrospectively analyzed.Results Among the 305 patients,19 patients(18 females and 1 male)showed PTMC incidentally after surgery.The mean age was (43.2 ± 12.8)years (ranging from 23 to 67 years old).All patients underwent subtotal thyroidectomy,including 17 endoscopic surgery and 2 open surgery.All frozen sections were benign during operation while pathologic results were PTMC after surgery.The average size of tumors was(2.2 ± 1.5) mm which all was unicentric with no lymph node enlargement intraoperatively.Immunohistochemistry showed that the positive rate of cytokeratin 19,galectin-3,mesothelial cell,and CD56 was 87.5%,43.8%,81.3% and 18.8%,respectively.There were 4 cases of B-raf V600E mutation found in 6 patients.All patients discharged 1 to 3 days after surgical treatment with no complication and received levothyroxine therapy with a suppressive dose of thyrotropin(TSH).131I therapy was not given.Conclusions PTMC is found more common in female and younger age under 45 years.Tumor is usually unicentric and less than 5 mm.Lymph node metastasis is rare.Immunohistochemistry and B-raf V600E mutant test can help the diagnosis.Initial endoscopic subtotal thyroidectomy is effective.There is no need of further surgery and 131I therapy.
RESUMO
Objective To explore the clinical value of indocyanine green near-infrared fluorescence imaging with methylene blue for the sentinel lymph node biopsy (SLNB) in early breast cancer.Methods SLNB was performed in forty patients by fluorescence navigation with methylene blue.Frozen section was performed,followed by conventional histopathology.Results The identification rate of SLN was 100%.100% of SLNs were fluorescent,with the average number being 2.88.92.5% of SLNs were stained blue,with the average number being 1.75.The presence of lymph node metastasis was observed in intraoperative biopsy in 7 patients,and a total dissection of the axillary lymph nodes was performed immediately.Metastatic lesions were not found in the identified lymph nodes by intraoperative biopsy and permanent pathological diagnosis in the other 33 patients.Conclusions Sentinel lymph nodes biopsy by fluorescence navigation with methylene blue was a feasible minimally invasive technology with high detection rate.
RESUMO
Objective To explore clinical characteristics,pathology,prognosis and proper treatment of pure mucinous breast carcinoma(PMBC).Methods Retrospective analysis Was carried out on patients with PMBC who were admitted from Jan.2004 to Dec.2010.Results PMBC patients accounted for 2.6%of all the patients with breast cancer treated at the same period.The mean age of PMBC patients was(55.28±15.73)years,ranging from 32 years to 81 years.The tumor diameter was from 1 to 10 cm and axillary lymph node involvement was 0%.Immunohistochemieal detection showed the positive rate of estrogen receptor(ER),progesterone receptor(PR),HER-2 and p53 was 96%,92%,0%and 32%respectively.All patients underwent operation and polychemotherapy(cyclophosphamide+Adriamycin,Paclitaxel+Adriamyein).12 cases received tamoxifen,13 cases received letrozole and 8 cases received postoperative irradiation.All the patients were followed up from 1 month to 6 years and the overall survival rate was 100%.Conclusions PMBC is a favorable histological type of breast carcinoma with good prognosis.Proper surgical and adjuvant therapy is important to improve survival rate and life quality.Molecular biologic parameters should be given enough consideration into prognosis evaluation.
RESUMO
Objective To study the risk factors for intra-abdominal infection after pancreaticoduodenecto-my. Methods Clinical data of 101 cases undergoing pancreaticoduodenectomy in our hospital from January 1994 to January 2008 were reviewed retrospectively. The risk factors were analyzed. Results The incidence of intra-abdomi-hal infection was 12.9% (13/101). Univariate analysis showed postoperative pancreatic,biliary and intestinal fistu-la,pulmonary infection,preoperative acute cholangitis and texture of the remnant pancreas were the risk factors for intra-abdominal infection(P<0.05). Multivariate Logistic regression revealed that postoperative pancreatic, biliary and intestinal fistula, pulmonary infection, preoperative acute cholangitis were independent risk factors (OR = 11.914,9.891 and 7.197 ) of intra-abdominal infection after pancreaticoduodenectomy. Conclusion Preventing and curing pancreatic ,biliary and intestinal fistula, pulmonary infection, preoperative acute cholangitis can decrease the incidence of intra-abdominal infection.
RESUMO
Objective To investigate the risk factors for pancreatic fistula after duct-to-mucosa pancreaticojejuuostomy (PD). Methods The clinical data of 101 cases undergoing duct-to-mucosa PD in our hospital from January 1994 to January 2008 were reviewed retrospectively. Results The incidence of pancreatic fistula was 9.9% (10/101). Univariate analysis showed level of preoperative jaundice(χ2=5.814, P= 0.016) , duration of jaundice (χ2= 4.17, P = 0.041 ), texture of the remnant pancreas (χ2=5.286, P = 0.021 ), diameter of pancreatic duct (χ2= 4.165, P = 0.041 ), blood loss during operation (χ2=5.273, P=0.022) were significantly associated with pancreatic fistula after duct-to-mucosa PD. Multivariate analysis regression revealed that texture of the remnant pancreas (OR = 13.355, P = 0.023), level of preoperative jaundice (OR = 12.126, P = 0.006), blood loss during operation (OR = 5.92, P =0.032 ) were independent risk factors. Logistic regression equation was as following: P=1/[<1+e-(-6.378+2.592 texture of the remrant pancress + 2.495 level of preopetative jaundice + 1.778 blood loss during operative)>]. The accuracy of the logistic equation was 92.1%. Conclusion Texture of the remnant pancreas, level of preoperative jaundice, blood loss during operation were the independent risk factors for the occurrence of PD after duct-to-mucosa PD. Improvement of operative technique and reduction of blood loss can decrease the incidence of pancreatic fistula.
RESUMO
Objective Laparoscopy-assisted distal gsstrectomy (LADG) with D1 + β lymph node dissection has become the most popular treatment for early gastric cancer in Asian countries. However, no one has shown the same clinical advantages with this procedure as with LADG with D1 + α lymph node dissection. The aim of this study was to compare the outcome of LADG with D1 + β to that of LADG with D1 + α lymph node dissection. Methods During the period of June 2002 through June 2006, LADG with D1 + α lymph node dissection was performed in 54 patients, and LADG with D1 + β lymph node dissection was performed in 42 patients. Surgical findings, clinicopathologic data, postoperative course, complications, and blood analysis findings were compared between the two groups. Differences were analyzed with Mann-Whitney U test and chi-square test. Results Patients in the two groups were comparable with respect to age, sex, body mass index, and stage and pathologic characteristics of gastric cancer. A significantly greater number of N2 lymph nodes were harvested by D1 + β lymph node dissection than by D1 + α dissection (5.9vs. 2.7, P<0.01). However, no significanees in the total number of retrieved lymph nodes (24.7 vs. 22.2) or perigastric lymph nodes dissected (18.9 vs. 19.4) were identified between the D1 + β and D1 +α groups. There was also no significant difference between the D1 + α and D1 + β groups with respect to operation time, blood loss, complication rate, time to first walking, first flatus, first eating, and first defecation, frequency of analgesics, volume of oral intake on postoperative day 7, weight loss, and postoperative hospital stay. Blood analysis showed there were no significant differences in white blood cell count, levels of C-reactive protein, and serum albumin. Conclusion The short-term outcome of LADG with D1 + β lymph node dissection is comparable to that of LADG with D1 + α lymph node dissection.
RESUMO
Objective To investigate the clinicopathologic features of gastrointestinal neuroendocrine carcinomas. MethodsThe diagnosis and treatment results of 45 cases were studied, and clinicopathologic features and immunohistochemical expressions of NSE, Syn and CgA were detected.ResultsMicroscopically carcinomas were divided into three types: type Ⅰ(25 cases), type Ⅱ(10 cases) and type Ⅲ(10 cases). The histologic categories were correlated with lymph node metastasis significantly( P0.05). The 5-year survival rate for type Ⅰ, type Ⅱ and type Ⅲ was 70%, 65% and 52%, respectively.ConclusionsThe combination of NSE, Syn and CgA immunohistochemical stainnig is necessary for the diagnosis of gastrointestinal neuroendocrine carcinomas. The histologic classification is coincident with the requirement of clinical treatment and prognosis.
