RESUMO
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.
RESUMO
@#Objective To compare the efficacy of different rehabilitation models on acalculia after acquired brain injury. Methods 113 cases were randomly assigned to 3 groups: control group(n=37), computer-assisted training group(n=38) and face-to-face training group(n=38). The control group just received cognitive dysfunction evaluation. The training groups received cognitive rehabilitation training 5 days a week and 30 minutes a day which sustained for 6 weeks. And 33 patients were selected to prolong for 12 weeks. They were evaluated with Revised EC301Calculation and Number Processing Battery in Chinese version (EC301-CR) at the beginning, the 6th week point and the 12th week point respectively. Results 6-week after treatment, The performance of both the computer-assisted training group and face-to-face training group significantly improved(P<0.001); It showed that computer-assisted group>face-to-face group>control group(P<0.001) both 6 weeks and 12 weeks latter. Significant negative correlation was found between age and performance of EC301-CR(P<0.05).Conclusion The effect of computer-assisted training on acalculia is superior to face-to-face training; The first 6 weeks of training is the best period for rehabilitation; The younger the patient is, the better results are.
