RESUMO
OBJECTIVE@#To evaluate the feasibility and safety of one- stage bilateral video-assisted thoracic surgery (VATS) for resection of bilateral multiple pulmonary nodules (BMPNs).@*METHODS@#We analyzed the clinical characteristics, pathological features, perioperative outcomes and follow-up data of 41 patients with BMPNs undergoing one-stage bilateral VATS from July, 2011 to August, 2021.@*RESULTS@#One-stage bilateral VATS was performed uneventfully in 40 of the patients, and conversion to open surgery occurred in 1 case. The surgical approaches included bilateral lobectomy (4.9%), lobar-sublobar resection (36.6%) and sublobar-sublobar resection (58.5%) with a mean operative time of 196.3±54.5 min, a mean blood loss of 224.6±139.5 mL, a mean thoracic drainage duration of 4.7±1.1 days and a mean hospital stay of 14±3.8 days. Pathological examination revealed bilateral primary lung cancer in 15 cases, unilateral primary lung cancer in 21 cases and bilateral benign lesions in 5 cases. A total of 112 pulmonary nodules were resected, including 67 malignant and 45 benign lesions. Postoperative complications included pulmonary infection (5 cases), respiratory failure (2 cases), asthma attack (2 cases), atrial fibrillation (2 cases), and drug-induced liver injury (1 case). No perioperative death occurred in these patients, who had a 1-year survival rate of 97.6%.@*CONCLUSION@#With appropriate preoperative screening and perioperative management, one-stage bilateral VATS is feasible and safe for resection of BMPNs.

Objective To explore the feasibility and efficacy of endoscopic balloon dilation in treatment of esophageal stenosis caused by operation of congenital esophageal atresia. Methods A retrospective analysis was performed on data of 218 children with type Ⅲ esophageal atresia, who underwent surgery in Zhengzhou Children' s Hospital from January 2009 to December 2017. The occurrence of postoperative complications and efficacy of endoscopic balloon dilation in treatment of esophageal stenosis was analyzed. Results Among the 218 patients with congenital esophageal atresia, 92 were type Ⅲa and 126 were type Ⅲb. Postoperative anastomotic leakage occurred in 46 cases (21. 1％), including 29 (31. 5％) of type Ⅲa and 17 (13. 5％) of type Ⅲb. Postoperative anastomotic stenosis occurred in 53 cases (24. 3％), including 29 ( 31. 5％) of type Ⅲa and 24 ( 19. 0％) of typeⅢb. The incidence of anastomotic leakage and anastomotic stenosis in different types was significantly different (χ2=10. 383, P=0. 001; χ2=4. 497, P=0. 034). The 53 cases of anastomotic stenosis underwent 123 times of endoscopic balloon dilation, with mean time of 3. 5±1. 6, and were finally clinically recovery. No esophagus perforation occurred. Among them, 29 cases of type Ⅲa underwent 73 times with mean of 4. 0±1. 8, and 24 cases of type Ⅲb underwent 50 times with mean of 2. 5±0. 7. The difference between the two types was statistically significant (t=-4. 053, P=0. 027). Conclusion Children with type Ⅲa esophageal atresia has a higher incidence of anastomotic stenosis and leakage, and more times of esophageal dilation. Endoscopic balloon dilation is safe and effective in treatment of esophageal stenosis after surgery for patients with congenital esophageal atresia.
RESUMO
Objective To compare the clinical efficacy of two surgical methods for the treatment of anal fissures in elderly patients.Methods A total of 138 elderly patients with anal fissures treated at our hospital from January to December 2016 were randomly divided into the conventional method group(69 cases) and the modified method group (69 cases).Patients in the conventional method group were treated with lateral sphincterotomy,while patients in the modified method group were treated with modified longitudinal sphincterotomy with transverse suture.Outcomes of treatment,VAS scores,incision wound infection rates,postoperative voiding dysfunction rates and recurrence rates were compared.Results There was no significant difference in overall effectiveness between the modified method group (98.6％)and the conventional method group(94.2％) (x2=1.8677,P=0.1717).The rates of incision wound infection,moderate postoperative urinary retention and recurrence in the conventional method group(8.7％,42.0％ and 10.1 ％,respectively)were significantly higher than those in the modified methods group(0.0 ％,15.9 ％ and 0.0％,respectively) (x2 =4.3561,11.4061 and 5.4177,respectively,P =0.0369,0.0007 and 0.0199,respectively).At 12 hours after operation,favorable VAS scores and incision healing times were observed in the modified method group,compared with the conventional method group,and the differences were statistically significant(each P＜0.05).Conclusions Modified longitudinal sphincterotomy with transverse suture produces about the same overall effectiveness as does lateral sphincterotomy in the treatment of elderly patients with anal fissures,but it is superior in reducing incision wound infection,moderate postoperative voiding dysfunction,recurrence and pain intensity,and in promoting incision healing.
RESUMO
Objective To compare and investigate the efficacy of small bone window via lateral fissure and cranial awl hole puncture aspiration via temporal lobe in treatment of hypertensive intracerebral hemorrhage (HIH) in basal ganglia. Methods Eighty-two patients with HIH in basal ganglia were divided into group A (34 cases) and group B (48 cases) by random digits table method. The patients in group A underwent small bone window via lateral fissure, and the patients in group B underwent cranial awl hole puncture aspiration via temporal lobe. The hematoma clearance rate, short-term effects, Barthel index, Scandinavian stroke scale (SSS) score and complications were compared between 2 groups. Results The Hematoma clearance rate and excellent rate in group A were significantly higher than those in group B:(91.12 ± 6.55)%vs. (55.83 ± 4.32)%and 52.94%(18/34) vs. 33.33%(16/48), the incidence of complications was significantly lower than that in group B:5.88%(2/34) vs. 22.92%(11/48), and there were statistical differences (P<0.05). The SSS score 14 d after operation and Barthel index 60 d after operation in group A were better than those in group B:(29.72 ± 6.39) scores vs. (26.43 ± 6.11) scores and (83.91 ± 17.82) scores vs. (72.34 ± 15.62) scores, there were statistical differences (P<0.05 or<0.01). Conclusions The efficacy of small bone window via lateral fissure in treatment of HIH in basal ganglia is better than cranial awl hole puncture aspiration via temporal lobe, however, surgical trauma is relatively large, and operation should be a reasonable choice according to the specific circumstances of patients.
RESUMO
[Objective]To explore the correlation of the expression of alpha-fetoprotein(AFP)mRNA in the peripheral blood and postoperative survival and metastasis of patients with liver cancer.[Methods] A total of 66 patients with liver cancer who received radical resection surgery from January 2005to December 2006 was enrolled in this study.The cell total RNA was extracted from peripheral blood and the expression of AFP mRNA was detected by nested PCR.All the patients were followed up for 60 months after surgery.[Results]The expression rate of AFP mRNA in the peripheral blood was 40.91％(27/66).The expression of AFP mRNA in the peripheral blood in patients with liver cancer was significantly related to microvascular invasion and metastasis(P ＜ 0.05 or ＜ 0.01),but the expression had no relationship with sex,age,HBV infection,cirrhosis,AFP concentration,tumour size and number,and Edmondson grading(P＞0.05).The overall 1,2,and ＞ 3 years survival rates of patients with positive AFP mRNA after surgery were 66.7％(18/27),38.9％(7/18),28.6％(2/7),respectively.The overall 1,2,and ≥3 years survival rates of patients with negative AFP mRNA after surgery were 84.6％(33/39),60.6％(20/33),45.0％(9/20).There was statistical significance between the survival rates of AFP mRNA-negative patients and AFP mRNApositive patients(P ＜ 0.01).[Conclusions] The detection of AFP mRNA in the peripheral blood may provide clue for early microscopic metastasis.It can be a prediction index for postoperative recurrence.
RESUMO
Objective To determine the serum levels of macrophage migration inhibition factor (MIF) and tumor necrosis factor-α (TNF-α) in patients with vitiligo,and to investigate their clinical significance.Methods The serum concentrations of MIF and TNF-α were determined by enzyme linked immunosorbent assay (ELISA) and radioimmunoassay respectively in 66 patients with vitiligo and 30 healthy controls.Results The patients with vitiligo vulgaris showed a significant higher serum level of MIF and TNF-α compared with the healthy controls ((9.56 ± 1.65) vs.(5.18 ± 0.81 ) μg/L,(2.38 ± 0.37) vs.(1.78 ± 0.21 ) μg/L,both P ＜ 0.01 ).There was a positive correlation between the serum level of MIF and TNF-α (r =0.89,P ＜ 0.05).No statistical difference was observed in the serum levels of MIF or TNF-α between the healthy controls and patients with segmental vitiligo (both P ＞ 0.05).The serum level of MIF was significantly higher in patients with progressive vitiligo than in those with stable vitiligo (P ＜ 0.01 ).Conclusions MIF and TNF-α might play a certain role in the pathogenesis of vitiligo,and MIF may be related to the activity of vitiligo vulgaris.
RESUMO
Objective To investigate the expression of LRP16 gene in lung cancer, and explore its clinicopathological significance. Methods Fresh resected tissues from 54 patients with primary lung cancer were collected and the clinicopathological data were gathered. The expression of LRP16 protein in cancer tissues and the matched normal tissues were determined by Western blotting, and the relationship between LRP16 expression and clinicopathological data was analyzed. It was defined as overexpression when the LRP16 expression of cancer tissues was twice or more higher than that of matched normal tissues. Results The LRP16 was overexpressed in 15 out of 54 patients with lung cancer (27.8%). Among the 23 patients with adencarcinoma, the overexpression of LRP16 was found in 11 cases (47.8%), while in the patients with squamous carcinoma, the overexpression of LRP16 was only found in 4 out of 27 cases (14.8%), and there was a significant difference between the two groups (Pearson test, P=0.0258). Besides, very low expression or non-expression of LRP16 was found in 2 large cell lung cancer and 2 small cell lung cancer. The overexpression rate of LRP16 was 20.0% (2/10) in tumor with diameter less than 3cm and 29.5% (13/44) in tumor with diameter ≥3cm, and there was no significant difference between the two groups (Pearson test, P=0.7224). Conclusions There were significant differences of LRP16 overexpression in cases of adencarcinoma or squamous carcinoma with or without lymphatic metastasis. It is suggested that LRP16 is a tumor-related gene of lung cancer, and may play an important role in molecular staging of lung cancer.
RESUMO
Objective To summarize the characteristics on diagnosis and therapy of adult diaphragmatic eventration. Method The clinical data of 26 patients with adult diaphragmatic eventration, hospitalized in General Hospital of PLA from 1988 to 2009, were retrospectively analyzed. The 26 patients, 14 males and 12 females, were aged from 26 to 66 (mean 44.0?5.7), with disease course of 8 months to 17 years. Among them 25 suffered from left and 1 from right diaphragmatic eventration; 24 with total and 2 with localized diaphragmatic eventration; of them 2 without symptoms were detected in physical examination, and among the 24 remainders 18 were with the symptoms of thoracic discomfort after eating, 8 with dyspnea after activities, 14 with hiccup, vomiting and abdominal discomfort. Most of the patients had more than one symptom. All patients received operations via the chest cavity under general anesthesia, 24 cases were performed by double mattress suture with diaphragm discission, while 2 cases by fold suture without diaphragm discission. Results Symptoms relief was reported in 24 patients at the early stage after operation. Eighteen patients were followed up for one year, and 15 of them received chest radiograph, among whom the normal diaphragm localization were in 13 cases and relatively higher diaphragm localization in 2 cases, while the other 3 patients received no re-examination of chest radiograph. Among the 18 cases receiving one year of follow-up, 10 cases got complete disappearance of symptoms, 6 cases got symptoms relieved or partially disappeared, and 2 patients got symptom relapsed. Conclusion Surgical outcome, especially the double mattress suture is satisfactory for adult diaphragmatic eventration.
