Objective:To study the safety and efficacy of laparoscopic cholecystectomy (LC) in treatment of T2a and lower stages of gallbladder carcinoma.Methods:A retrospective study was performed on patients who were diagnosed with gallbladder cancer and underwent surgical treatment from January 2016 to January 2021 at Hunan Provincial People's Hospital. These patients were divided into the simple treatment group and the radical treatment group based on the surgical methods used. The simple treatment group consisted of 64 patients who underwent LC for accidental gallbladder cancers. The radical treatment group consisted of 30 patients who underwent laparoscopic radical cholecystectomy (LRC). The baseline characteristic of the two groups of patients were matched in a 1∶1 ratio using propensity score matching. After matching, there were 26 patients in each of the 2 groups. There were 7 males and 19 females in the simple group, with mean ± s. d. age of (60.6±9.6) years. There were 8 males and 18 females, with mean ± s. d. age (60.9±9.1) years in the radical treatment group. Blood loss, operation time, postoperative hospital stay, biliary leakage, acute pulmonary embolism, and incisional infection were compared between the two groups.Results:In the simple group, the operative time was (78.7±62.9) min, intraoperative blood loss was (10.7±11.6) ml and postoperative hospital stay was (4.4±2.6) d. These results were significantly better than those in the radical group with operative time (298.7±101.3) min, intraoperative blood loss (161.9±96.7) ml and postoperative hospital stay (9.9±4.0) d (all P<0.05). There were no significant difference in the postoperative complications and disease free survival rates between the two groups (both P>0.05). Conclusion:LC was safe and effective for treatment of T2a and lower stages of gallbladder cancer, and it could achieve a similar disease-free survival rate as LRC.

Objective:To analyze the causes of postoperative stricture of biliary-enteric anastomotic for congenital choledochal cysts.Methods:These 28 patients underwent salvage operation on an average 15 years (0.2-25 years) after initial surgeries at the Department of Hepatobiliary Surgery, Hunan Provincial People's Hospital from Jan 2014 to Jun 2018.Results:In 26 patients the biliary-enteric anastomotic stenosis was benign, and in 2 the stricture was caused by cancerration. In 26 cases the Roux-en-Y hepaticojejunostomy was redone,among them 8 cases underwent concurrent hepatectomy for a better exposure of the intrahepatic bile duct. In 2 cases the anastomotic stenosis was found to be caused by canceration with extensive intraabdominal metastasis ,an external drainage was adopted. There were no inhospital deaths, and no serious complications. The postoperative follow-up time was 6-67 months. Two cancerated patients died within half a year, and the remaining patients had no long-term complications.Conclusions:Biliary-enteric anastomotic stenosis is one of the serious complications in postoperative patients for congenital choledochal cysts. Hence a wide, tension free biliary-enteric anastomosis performed by a experienced hand is necessary.

Objective: To investigate the self-reported prevalence, clinical characteristics, complications of allergic rhinitis (AR) and the sensitization of outdoor air pollen allergens in children in the Inner mongolia grassland region. Methods: A multistage, stratified and random clustered sampling with a face-to-face interview survey study in children from 0 to 17 years old was performed together with 10 common allergen skin prick tests (SPT) and measurements of the daily pollen count in 6 regions in the Inner mongolia grassland region from May to August of 2015. SAS 9.4 software was used for data analysis. Results: A total of 2 443 subjects completed the study. The self-reported prevalence of AR was 26.6%. The prevalence of boys was higher than that of girls (28.8% vs 24.3%, χ²=6.157, P<0.05). Subjects from urban areas showed higher prevalence than rural areas (34.7% vs 18.8%, χ²=79.107, P<0.05). There was significant regional difference in the prevalence of AR among the six areas investigated (χ²=221.416, P<0.05). The main clinical symptoms of AR were sneezing (88.2%) and nasal congestion (78.6%). Among combined diseases, asthma accounted for 16.5% (107/650), rhinoconjunctivitis accounted for 47.9% (311/650). The peak season of AR was April and July, with the top SPT positive allergens of Artemisia species and chenopodium in this area. Conclusions The prevalence AR in children in the Inner mongolia grassland region is extremely high. Sneezing is the main clinical symptom. Rhinoconjunctivitis is the most common combined disease. High summer and autumn pollen exposure is the main cause of AR.

Efficient measurement of administrative departments at public hospitals is key to performance appraisal for such units. The authors analyzed the current situation and problems of performance management of such departments of public hospitals, and made case studies for the formulating and implementing process of the performance appraisal system.Furthermore, they probed into appraisal methods for these departments and presented a performance appraisal model of " expectation-response" . Combined with the practice of the case hospitals, the authors recommended an annual personalized evaluation indicator system. Based on analysis of the operation process of the case hospitals from 2016 to 2018, namely theory study-practical exploration-experience summary-program readjustment for further practice. These efforts studied the implementation framework of performance management for these departments, summarized the by-stage practice experiences of the appraisal from the " basic version" to " specialized version" . Thus the paper provided references for their performance management of these hospitals.

Objective: To evaluate the implementation effectiveness of performance management for administrative departments. Methods: By means of questionnaires, the authors made a comparative analysis of the performance perception of service recipients of these departments before and after the implementation of the scheme, and the change of external performance appraisal results of the case hospital was analyzed through third-party evaluation. Then face to face interviews were used to conduct performance communication with the management staff. Results: Questionnaire results showed that the satisfaction of those served by these administrative departments for their work improvement and work results was generally elevated, scoring 4.31 for their satisfaction elevation(higher than 3.0 of the neutral attitude). A third party external performance appraisal indicated a capability enhancement as shown by the hospital in the appraisal indicators by the hospital′s authorities, scoring 91.52 in 2018 as compared to 82.34 in 2016. In-depth interviews exhibited that the ranking of the total scoring of performance appraisal of these departments was more in line with the staff′s psychological feelings. These departments also agreed with the appraisal system, the algorithm of performance scoring and the appraisal results. Conclusions The performance management of these departments of the hospital had achieved the goal of effective implementation and elementarily improved the efficiency of the hospital′s internal management.

Taking the occurrence and development of general consent as the research object, this paper compared the differences between the ethical characteristics of broad consent and informed consent of specific research through the analysis of the content revision process of broad consent in the U.S. Broad Rules, and tried to explore the feasibility of implementing broad consent in Chinese medical institutions.

Objective To investigate the cognition of medical staff on the control and treatment of venous thromboembolism ( VTE) at the municipal general hospitals in Beijing, for due countermeasures. Methods Customized questionnaires were used to survey the medical staff at 7 general hospitals in Beijing. The data so acquired were divided into approval items and disapproval items to calculate the ratio of approval items, while the comparison between those of different specialties and academic titles was subject to logistic regression analysis. Results 2 496 valid questionnaires were recovered, and the results showed that over 95% of them recognized the necessity of the VTE control and treatment work in the hospital, yet they need to improve their professional knowledge in this regard. There were differences in the cognition level among different specialties, and the higher the professional title, the better the recognition. Top three concerns for VTE work were increased workload, increased hospitalization expenses and extended hospital stay in turn. Top three difficulties in the work were patient′s compliance, coordination of auxiliary departments, and doctors′ cognition and involvement. Conclusions Cognition of VTE needs to be enhanced, and it is imperative to improve the VTE control and treatment system, carrying out the work in a scientific, standardized and economic manner.

In the evaluation of medical postgraduate scholarship, objective method is adopted to evaluate subjective indicators. According to the specific practices for experts and the views of students to establish a set of subjective and objective indicators combined with the evaluation index system, objective indicators including research ability, academic achievement, various school activities, subjective indicators such as ethics, communication and coordination ability, innovation ability etc. To evaluate the subjective index according to the analysis, the inherent requirements of subjective index application case scenario simulation and peer evaluation and other objective methods, we aim to eliminate the scholarship evaluation process of subjective indicators "passing" or "useless" phenomenon, more fair and equitable selection of truly outstanding students.

Objective To evaluate the application value of right hemihepatic blood flow occlusion in the anatomical right posterior lobectomy. Methods Clinical data of 81 patients undergoing anatomical right posterior lobectomy in Hunan Provincial People's Hospital between January 2010 and February 2015 were retrospectively analyzed. The patients were divided into three groups according to the methods of liver blood lfow occlusion. In the right hemihepatic blood lfow occlusion group (methodⅠgroup), there were 26 cases including 12 males and 14 females with a mean of (48±9) years. In the regional blood flow occlusion of right posterior lobe group (method Ⅱ group), there were 34 cases including 15 males and 19 females with a mean of (48±10) years. In the Pringle's maneuver group (methodⅢgroup),there were 21 cases including 10 males and 11 females with a mean of (48±10) years. The informed consents of all patients were obtained and the local ethical committee approval was received. In methodⅠgroup, the right hepatic pedicle occluding band was prepared for spare, or the right hepatic artery and the right branch of portal vein were dissected and occluded separately. In methodⅡgroup, the right posterior branch of right hepatic artery and the right posterior branch of portal vein were separated, ligated and resected on the basis of methodⅠ. In methodⅢgroup, porta hepatis was not dissected. The operation time, intraoperative hemorrhage volume and blood transfusion were observed in three groups. Clinical data among three groups were compared by one-way ANOVA and LSD-t test. Results The operation time in methodⅠgroup was (168±52) min, which was significantly shorter compared with (216±39) and (193±43) min in method Ⅱ and method Ⅲgroup (LSD-t=-4.093, -1.772; P<0.05). The intraoperative hemorrhage volume in method Ⅰ group was (200±62) ml, which was signiifcantly less compared with (403±38) and (303±37) ml in methodⅡand methodⅢ group (LSD-t=-15.671, -12.735; P<0.05). Conclusion Right hemihepatic blood flow occlusion is a safe and feasible technique for controlling hemorrhage during the anatomical right posterior lobectomy, which signiifcantly decreases the intraoperative hemorrhage volume, shortens operation time and reduces surgical risk.

ObjectiveTo investigate the clinical application value of two-step separation approach in laparoscopic left lateral sectionectomy (LLLS).MethodsA total of 156 patients undergoing LLLS with two-step separation approach in Hunan Provincial People's Hospital between January 2009 and September 2014 were included in this prospective study. Among the 156 patients, 76 were males and 80 were females with the age ranging from 18 to 75 years old and the median of 56 years old. The informed consents of all patients were obtained and the local ethical committee approval had been received. The patients were in bladder lithotomy position or straddle position and pneumoperitoneum was established with 4-hole approach and periumbilical puncture. Hepatectomy was performed using two-step separation approach. The liver parenchyma was dissected to the plane of left lateral hepatic pedicle-left hepatic vein using ultrasonic scalpel along the left of falciform ligament. Then, the hepatic pedicle and the left hepatic vein was dissected using Endo-GIA stapler.ResultsAll patients completed the surgery successfully and no case was converted to laparotomy. Eighty-nine patients underwent simple left lateral hepatic artery occlusion and 67 patients did not undergo hepatic inlfow occlusion. The median operation time was 85 (53-150) min and the liver dissection time was 17 (8-35) min. The intraoperative blood loss was 25 (10-100) ml and the postoperative length of stay was 7 (5-10) d. No death case and no serious postoperative complication was observed. Only 7 patients developed mild bile leakage and recovered after effective drainage.ConclusionTwo-step separation approach in LLLS is safe and easy, which can be taken as a standard operation and widely popularized.
