A new classification of left apicoposterior segmental bronchus and its clinical significance / 中国胸心血管外科临床杂志

@#Objective    To analyze a new classification of the left apicoposterior segmental bronchus and summarize its clinical significance. Methods     We accessed the computed tomography imaging data of the inpatients treated in the Department of Thoracic Surgery, Henan Provincial People's Hospital between January and November 2021. We observed and classified the branching pattern of the left apicoposterior segmental bronchus (B1+2) using three-dimensional computed tomography bronchography and angiography (3D-CTBA) technique. And we filtered out the patients who underwent thoracoscopic left apicoposterior segmentectomy and analyzed their clinical data retrospectively to summarize the instructing significance of different bronchial classification in the accurate and safe operation of left apicoposterior segmentectomy. Results     Finally 240 patients were collected, including 131 males and 109 females with a median age of 51.0 (19.0-77.0) years. The anatomical pattern of the left apicoposterior segmental bronchus was divided into four main types based on the branching pattern of the outer subsegmental bronchi (B1+2c): type Ⅰ 10% (24 patients), type Ⅱ 54% (130 patients) , type Ⅲ 17% (40 patients) , type Ⅳ 18% (43 patients) and other variations 1% (3 patients). Thirty-two patients smoothly underwent thoracoscopic left apicoposterior segmentectomy, including 23 patients of type Ⅰ and type Ⅱ receiving LS1+2 resection, the other 9 patients of type Ⅲ and type Ⅳ receiving LS1+2 resection (3 patients), LS1+2c resection (4 patients) and LS1+2(a+b) resection (2 patients). Conclusion     This new classification systematically and concisely elucidates the branching characteristics of the left apicoposterior bronchus. Different branching types are instructive to the left apicoposterior segmentectomy.

Clinical analysis of 8 cases of transverse testicular ectopia / 中华实用儿科临床杂志

Objective:To study the clinical manifestations, diagnostic methods and therapeutic outcomes of transverse testicular ectopia (TTE).Methods:Clinical data of 8 cases of TTE treated in the Department of the First Urologic Surgery, Xinxiang Central Hospital and Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from May 2004 to November 2018 were retrospectively analyzed.Clinical manifestations, diagnostic methods, surgical treatment and follow-up results of TTE were summarized.Results:The age of 8 cases of TTE was 1 year 5 months to 5 years.Among the 8 cases of TTE, 6 cases were involved with the left side and 2 cases with the right side.All patients were admitted due to scrotal emptiness.Three cases were combined with persistent Müllerian duct syndrome (PMDS) and 1 case combined with hypospadias.Preoperative diagnosis of TTE was definitely made in 5 cases, involving 4 cases diagnosed by ultrasound and 1 case diagnosed by magnetic resonance imaging.Laparoscopy was performed in 2 cases, including 1 case treated with laparoscopic scrotopexy, and the other one transferred to an open surgery of trans-septal orchiopexy due to poor development of the spermatic cord.Open surgery was performed in 6 cases, including 1 case with bilateral testicular fixation in the ipsilateral scrotum due to adhesion of spermatic cord closely, and 5 cases with trans-septal orchiopexy.Müllerian ducts residues were excised during surgery in 3 cases combined with PMDS.Postoperative wound infection or hematoma was not reported in all cases.Orchiepididymitis and the involvement of contralateral testes occurred in 1 case treated with trans-septal orchiopexy at 11 months postoperatively, which were relieved after anti-inflammatory treatment.All cases were postoperatively followed up for 3-48 months, and the development and blood supply of bilateral testes were detected normal by ultrasonography.Postoperative testicular atrophy was not reported.Conclusions:The possibility of TTE should be considered in patients with unilateral cryptorchidism combined with contralateral inguinal mass.Ultrasonography is preferred to the diagnosis of TTE.Laparoscopic surgery plays an important role in the diagnosis and treatment of TTE, which is helpful to identify abnormalities in the Müllerian duct structure.

Analysis of risk factors for recurrence of differentiated thyroid carcinoma after surgical resection combined with iodine-131 and TSH suppression therapy / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the risk factors of recurrence after surgical resection of differentiated thyroid carcinoma combined with iodine-131 and TSH（Thyroid stimulating hormone） inhibition therapy. Methods:From January 2015 to April 2020, the clinical data of patients with structural recurrence and without recurrence were retrospectively collected after surgical treatment combined with iodine-131 and TSH inhibition therapy in the First Medical Center of PLA General Hospital. The general conditions of the two groups of patients were analyzed and the measurement data in line with the normal distribution was used for comparison between groups. For measurement data with non-normal distribution, the rank sum test was used for inter-group comparison. The Chi-square test was used for comparison between the counting data groups. Univariate and multivariate regression analyses were used to determine the risk factors associated with relapse. Results:The median follow-up period was 43 months（range 18-81 months） and 100 patients（10.5%） relapsed among the 955 patients. Univariate analysis showed that tumor size, tumor multiple, the number of lymph node metastases>5 in the central region of the neck, and the number of lymph node metastases>5 in the lateral region were significantly correlated with post-treatment recurrence（P<0.001, P=0.018, P<0.001, P<0.001）. Multivariate analysis showed that tumor size（adjusted odds ratio OR: 1.496, 95%CI: 1.226-1.826, P<0.001）, tumor frequency（adjusted odds ratio OR: 1.927, 95%CI: 1.003-3.701, P=0.049）, the number of lymph node metastases in the central neck region>5（adjusted odds ratio OR: 2.630, 95%CI: 1.509-4.584, P=0.001） and the number of lymph node metastases in the lateral neck region>5（adjusted odds ratio OR: 3.074, 95%CI: 1.649-5.730, P=0.001） was associated with tumor recurrence. Conclusion:The study showed that tumor size, tumor multiple, the number of lymph node metastases in the central region of the neck>5 and the number of lymph node metastases in the side of the neck >5 are independent risk factors for recurrence of differentiated thyroid cancer after surgical resection combined with iodine-131 and TSH inhibition therapy.

Chinese experts consensus on standardized surgical management of specimens from radical gastrectomy (2022 edition) / 中华胃肠外科杂志

In the standardized diagnosis and treatment process of advanced gastric cancer, there is a unappreciated key link between standard radical surgery and accurate pathological reports. That is, the process of dissection, fixation, sampling and recording of the specimen by the surgeons, starting from specimen isolation to the management of the pathologist. Standardizing this process can not only accurately reflect the detailed distribution and exact number of lymph nodes, but also clarify the pathological stage of gastric cancer, so as to make adjuvant treatment plans. Moreover, it can also reflect the scope of intraoperative lymph node dissection to ensure the standardized implementation of surgery, including the overall dissection principle (en bloc resection), and therefore can provide a solid foundation for later related researches. So far, there is still a lack of complete and unified standard for the surgical management of specimens after radical gastrectomy in China. On the basis of the relevant researches and clinical practice about specimen management at home and abroad, the Chinese Journal of Gastrointestinal Surgery, in the name of the Gastric Cancer Professional Committee, Chinese Anticancer Association, as well as the Oncogastroenterology Professional Committee, Chinese Anticancer Association, organized dozens of experts to formulate a consensus on the standardized surgical management of specimens after repeated discussions and revisions for two years. This consensus is aimed to standardize the preparations, basic requirements and sample processing procedures before the surgical treatment of postoperative specimens after a radical surgery for gastric cancer patients, including the processing time of specimens, the processing and data archiving of gastric specimens, and lymph node grouping, sorting and fine sorting records, etc and with the purpose of standardizing the surgical treatment of postoperative specimens on the basis of standardized diagnosis and treatment of gastric cancer, in order to further promote the high-quality development of gastric cancer surgery in China.

Surgical treatment of axillary odor in Chinese patients: a meta analysis / 中华医学美学美容杂志

Objective:In China, although axillary osmidrosis is common in plastic surgery, there is no standard procedure for the treatment of axillary osmidrosis. So we compared the efficacy of 6 axillary osmidrosis surgical treatments with network meta-analysis in order to provide reference for the clinical surgical treatment of axillary osmidrosis in Chinese patients.Methods:From January 2018 to December 2021, Chinese and English databases including Wanfang Database, VIP Chinese Science and Technology Periodical Full-text Database (VIP) and CNKI, PubMed, Cochrane Library, Embase were searched by the Plastic Surgery Department of Zhangqiu People′s Hospital in Jinan, Shandong province. And some relevant studies were collected for network meta-analysis.Results:47 studies including a total of 6543 subjects were identified for meta-analysis. After analysis, 4 of the 15 pairwise comparisons were not statistically significant, and the effect of swelling aspiration + subcutaneous pruning was more significant. According to the surface under the cumulative ranking curve (SUCRA), the efficacy of 6 surgical methods for the treatment of axillary osmidrosis was as follows: swelling aspiration + subcutaneous pruning > subcutaneous scratching+ subcutaneous pruning > subcutaneous pruning > fusiform skin resection > subcutaneous scratching > swelling aspiration.Conclusions:In surgical treatment of axillary osmidrosis, swelling aspiration + subcutaneous pruning is the best. It is worth popularizing in the clinical work of treating axillary osmidrosis patients. Due to the limitations of this study, the conclusion of this network meta-analysis still needs to be further confirmed by a well-designed randomized controlled trial.

Effects of slow intravenous infusion of low-dose mannitol on hemodynamics in patients after cardiac surgery under cardiopulmonary bypass / 中华胸心血管外科杂志

Objective:To investigate the effect of slow intravenous infusion of low-dose mannitol on the hemodynamics of patients after cardiopulmonary bypass.Methods:Prospective, continuous inclusion of 62 patients after cardiac surgery under cardiopulmonary bypass. By random number method, they were divided into normal treatment group(group C) with 29 cases and mannitol treatment group(group M) with 33 cases. Group C was treated according to the postoperative routine treatment measures. On the basis of conventional treatment, group M received intravenous infusion of 20% mannitol injection 0.25 g/kg at 1、8、24 hours after operation, and the intravenous infusion time was 60 minutes each time. According to the hemodynamic changes during the two groups of treatment, the effect of slow intravenous infusion of low-dose mannitol on patients after cardiopulmonary bypass under cardiopulmonary bypass was analyzed.Results:In group M, CI and SVI were significantly increased after use of mannitol than before, with statistical significance( P<0.01). SVRI showed a downward trend, and the changes were statistically significant after use of mannitol( P<0.01). PAWP increased first and then decreased after operation, and the changes were statistically significant after mannitol use than before( P<0.05). RAP and MPAP had no significant changes after the first use of mannitol, but the changes after the latter two use mannitol were statistically significant than before( P<0.05). Repeated-measurement data analysis of variance was performed on the hemodynamic parameters of each group, and the results were all P<0.01. Conclusion:Postoperative slow intravenous infusion of low-dose mannitol optimizes hemodynamic status, increases stroke volume, reduces cardiac preload, improves systemic and pulmonary circulation resistance, and promotes recovery of postoperative cardiopulmonary function.

The clinicopathological data of 15 patients with hepatocellular carcinoma who underwent laparoscopic anatomical right posterior sector combined with anterior-dorsal segment resection in the Sun Yat-sen Memorial Hospital of Sun Yat-sen University from September 2020 to August 2021 were collected. There were 9 males and 6 females, aged 66(range, 35?77)years. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination and telephone interview to detect tumor recurrence and survival of patients in the postoperative 90 days. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations. All the 15 patients underwent laparoscopic anatomical right posterior sector combined with anterior-dorsal segment resection successfully, without blood transfusion and conversion to laparotomy during the operation. The operation time, volume of intraoperative blood loss and occlusion time of first porta hepatis of the 15 patients were (155±17)minutes, (254±66)mL and (51±7)minutes, respectively. (2) Postoperative situations. The duration of postoperative hospital stay of the 15 patients was (7.4±2.1)days. Results of postoperative histopathological examination showed hepatocellular carcinoma and R 0 margins in all the 15 patients with a minimum distance from margin to tumor of (1.5±0.8)cm. There was none of the 15 patients transferred to intensive care unit, perioperative death or rehospitalization within 30 days after surgery. Of the 15 patients, 2 cases had postoperative complications, including 1 case with biliary fistula (grade Ⅰ of Clavien-Dindo classification) and 1 case with ascites (grade Ⅱ of Clavien-Dindo classification). Patients with complications were improved after washing and drainage, abdominal puncture and drainage. (3) Follow-up. All the 15 patients were followed up for the postoperative 90 days and none of them had tumor recurrence or death within postoperative 90 days. Conclusion:The laparoscopic anatomical right posterior sector and anterior-dorsal segment resec-tion for hepatocellular carcinoma is safe and feasible.

@#Takayasu arteritis (TA) is a primary, chronic, non-specific, inflammatory disease of the aorta and its larger branches. The pulmonary artery trunk and its branches could be impacted by TA, which could cause stenosis or occlusion of lesion vessels. TA also affects the normal function of the aortic valve and other heart valves, mainly due to valvular insufficiency. Aortic regurgitation caused by TA is mainly treated by surgical operation. In this review, the examination technique, operation timing, operation method and prognosis of aortic valve involved in TA are discussed systematically.

Treatment progress in minimally invasive intramedullary fixation for midshaft clavicle fracture / 中华创伤骨科杂志

Nowadays,more and more studies on mini-invasive treatment of clavicle fractures have been reported.Firstly,based on the newly published literature about intramedullary fixation for midshaft clavicle fractures,this paper reviews its indications and advantages.Next,the design characteristics,surgical procedures,therapeutic effects and latest treatment advances concerning the intramedullary implants are systemically demonstrated and compared.Intramedullary fixation can be used in most midshaft clavicle fractures except those with neurovascular lesions or with comminuted segments,or obsolete ones.The commonly used intramedullary implants include Kirschner wires,cannulated screws,titanium elastic nails,threaded nails,and second-generation intramedullary nails.Intramedullary fixation has potential advantages of a smaller incision,fewer complications,a lower refracture risk and faster bone healing but also limitations in strength and stability.However,more and more intramedullary implants,from cannulated screws to second-generation intramedullary nails,have been used in clinic,leading to fine therapeutic effects.New products are being developed to overcome the previous shortcomings.

Posterolateral minimal invasive plate osteosynthesis for medial open fractures of distal tibia and tibial shaft / 中华创伤骨科杂志

Objective To analyze the posterolateral minimally invasive plate osteosynthesis (MIPO) in the treatment of medial open fractures of distal tibia and tibial shaft.Methods From May 2016 to September 2017,16 medial open fractures of distal tibia and tibial shaft were treated with posterolateral MIPO at Department of Orthopaedics,The First Affiliated Hospital to Anhui University of Science and Technology.They were 10 men and 6 women,from 22 to 61 years of age(average,36.5 years).According to the Gustilo-Anderson classification,type Ⅰ fracture was identified in 5 patients,type Ⅱ fracture in 6 and type Ⅲ fracture in 5.Initially,all the patients received emergency external fixation or calcaneus traction before open reduction and internal fixation was performed when their conditions of soft tissue allowed.X-ray examination of the ankle joint with anteroposterior and lateral views was performed before and after operation.At the last follow-up,the function of ankle joint was evaluated according to the ankle-hindfoot score of American Orthopaedic Foot and Ankle Society (AOFAS).Results All the 16 patients were followed up for an average of 15.3 months (from 8 to 24 months).Fracture healing was achieved in all after an average time of 26.1 weeks (from 20 to 36weeks).There were no such complications as skin necrosis,wound dehiscence,deep infection,implants exposure or failure,or impingement of the flexor hallucis longus.The AOFAS ankle scores averaged 88.6 points (from 74 to 95 points),giving 9 excellent,6 good and one fair cases.Superficial infection occurred in 2 patients but healed after dressing care.Another case showed 5°varus deformity.Conclusion Application of posterolateral MIPO in the treatment of medial open fractures of distal tibia and tibial shaft can effectively protect the medial soft tissue,reduce postoperative wound complications,and safely expose,reduce and fixate the tibial fragments,leading to satisfactory outcomes.

Objective To summarize the experience of surgical treatment of severe ventricular septal defect (VSD) accompanied by pulmonary hypertension (PH) in little infants. Methods The clinical data of 11 patients with VSD accompanied by PH admitted to the Department of Cardiac Surgery of Tianjin Children's Hospital of the Pediatric Clinical College in Tianjin Medical University from January 2016 to January 2017 were retrospectively analyzed. There were 6 males and 5 females, with the ages of 3 - 6 months, mean (5.36±1.03) months and body weights 4.2 - 7.5 kg, mean (5.9±1.0) kg. Preoperatively, all patients had recurrent pneumonia and heart failure history. After 2 - 3 times of medical treatment in hospitals, the patients underwent sub-acute radical operation under cardiopulmonary bypass. All patients were followed-up with echocardiography, chest X-ray and electrocardiogram examinations at 3, 6 and 12 months after heart surgery. Results After operation, all the children spontaneously recovered the heart beats, the stay times in surgical intensive care unit (SICU) were 2 - 7 days, and total hospitalization times were 12 - 17 days. All patients were followed up for 12 months, no death occurred in the whole group, and the heart and lung functions recovered satisfactorily. Conclusions Little infants with large VSD and PH should undertake operation as early as possible. The patients with recurrent pneumonia, heart failure in a short term should receive medical and surgical doctors' cooperative treatment, and the disease situation ought to be adjusted with one's best ability to a stable status when the sub-acute surgery can be carried out safely.
