Objective:To study the clinical efficacy of laparoscopic radical cholecystectomy in the treatment of stage Ⅲ gallbladder cancer.Methods:The clinical characteristics and postoperative follow-up data of 184 patients (male 66, and female 118) who underwent radical cholecystectomy for stage Ⅲ gallbladder cancer at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, from May 2015 to May 2022, were retrospectively analyzed. The age was (67.0±8.6) years old (range 38 to 85 years old). There were 71 patients in the laparoscopic group and 113 in the open group. The general medical data, surgery-related indicators and complications were analyzed. Follow-up was completed by outpatient visits and by telephone.Results:The laparoscopic group showed better postoperative alanine aminotransferase [67.5 (40.0, 138.5) vs. 104.0 (45.0, 252.2) U/L] and aspartate aminotransferase [41.5 (26.0, 71.2) vs. 53.0 (30.2, 153.5) U/L] recovery, higher albumin levels [32.05 (30.18, 35.20) vs. 30.50 (27.70, 33.50) g/L], earlier abdominal drainage tube removal [8.00(6.00, 10.25) vs. 10.00(6.00, 13.00)d], shorter hospital stay [10.00(8.00, 15.25) vs. 14.00(9.00, 19.00) d] and lower incidences of complications [(14.1%(10/71) vs. 31.9%(36/113)] when compared with the open group (all P<0.05). The 1 year (49.1% vs 61.0%), 2 years (24.0% vs. 28.5%), 3 years (16.0% vs. 14.5%) overall survival ( P=0.640), and the 3 years progression-free survival (18.3% vs. 15.0%, P=0.463) showed no significant difference between the 2 groups. Conclusion:Laparoscopic surgery for AJCC TNM stage Ⅲ gallbladder cancer showed comparable results with open surgery. When compared with open surgery, laparoscopic radical resection of gallbladder cancer had the advantages of earlier removal of abdominal drainage tube, lower incidence of postoperative complications, and shorter hospital stay.

Objective:To study the effect of preoperative transcatheter arterial chemoembolization (TACE) on postoperative complications after hepatectomy in patients with hepatocellular carcinoma (HCC) by propensity score matching analysis.Methods:Of 1 666 patients with HCC undergoing hepatectomy in Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology and Tianyou Hospital of Wuhan University of Science and Technology from March 2015 to March 2021 were retrospectively screened. Of 262 patients were enrolled, including 236 males and 26 females, aged (50.3±11.8) years. Of 131 patients were enrolled in both the single surgery group and the combined group (preoperative TACE + surgical resection). Factors affecting the complications after hepatectomy in patients with HCC were analyzed using univariate and multivariate logistic regression method.Results:After matching the propensity score, the incidence of postoperative complications in the single surgery group was 22.1% (29/131), lower than that in the combined group [41.2% (54/131), χ 2=11.02, P<0.001]. The incidence of bile leakage in the single surgery group [2.3% (3/131)] was also lower than that in the combined group [(9.2% (12/131), χ 2=5.73, P=0.017]. Multivariate logistic regression analysis showed that the combined group ( OR=2.43, 95% CI: 1.28-4.61, P=0.007) had an increased incidence of postoperative complications, so did patients with a preoperative alpha-fetoprotein > 400 μg/L, anatomic hepatectomy, long operation time, and hilar occlusion. Conclusion:Preoperative TACE could be a risk factor for postoperative complications in patients with HCC, especially for the postoperative biliary leakage.

Hepato-pancreato-biliary diseases (HPBD) are often complicated. The diagnosis and treatment of HPBD involve many disciplines. The malignant degree of hepatobiliary pancreatic system is high, and the prognosis of patients is poor. The multidisciplinary team (MDT) brings specialists from different disciplines together to make a comprehensive and individualized treatment for patients. MDT is emerging in HPBD in recent years. MDT helps improve the accuracy of diagnosis and prognosis. However, there are still some controversies and obstacles in the application of MDT for patients with HPBD. We reviewed the development, current status and experience of MDT in the field of HPBD, analyze the current controversy and obstacles, and providing reference for its future application.

Objective    To evaluate the strategy of chemoradiotherapy following endoscopic R0 resection for esophageal cancer in M3-T1b stage. Methods    There were 45 esophageal cancer patients with M3-T1b stage with endoscopic R0 resection followed by additional chemoradiotherapy from ECETC (Esophageal Cancer Endoscopic Therapy Consortium) as a trial group with 34 males and 11 females at age of 61.37±7.14 years. There were 90 patients with esophagectomy from Fudan University Shanghai Cancer Center as a control group with 63 males and 27 females at age of 61.04±8.17 years. Propensity score match (1:2) was used to balance the factors: gender, age, position, depth of invasion and lymphovascular invasion (LVI), which may influence the outcomes. Overall survival (OS) rate, relapse free survival (RFS) rate, and local recurrence rate were compared between the two groups. Result    There was no statistical difference (HR=2.66 with 95%CI 0.87 to 8.11, P=0.179) in terms of OS rate between the two groups. One, two and three years overall survival rate of patients in the control group was 93%, 86%, and 84%, respectively. Nobody died in the trial group within 3 years after surgery. The RFS rate between the two groups didn’t significantly differ (HR=1.48, 95% CI 0.66 to 3.33, P=0.389). One, two and three years RFS rate of patients in the contorl group was 87%, 78%, and 76%, respectively, while 97%, 93%, and 73% in the trial group, respectively. The local recurrence rates between the two groups didn’t significantly differ either ( HR=0.53，95%CI 0.13 to 2.18, P=0.314). One, two and three years local recurrence rate of patients in the control group was 5%, 6% and 6%, respectively, while 0%, 0% and 21% in the trial group, respectively. Conclusion    Similar outcomes are found regarding OS, RFS and local recurrence rates between the two groups. The strategy of endoscopic R0 resection followed by additional chemoradiotherapy has prospect for the treatment of esophageal cancer in M3-T1b stage. And this kind of therapy may be provided for those with risk factors or can not tolerate surgery.

Coronavirus disease 2019 (COVID-19) is a highly contagious disease and a serious threat to human health. COVID-19 can cause multiple organ dysfunction, such as respiratory and circulatory failure, liver and kidney injury, disseminated intravascular coagulation, and thromboembolism, and even death. The World Health Organization reports that the mortality rate of severe-type COVID-19 is over 50%. Currently, the number of severe cases worldwide has increased rapidly, but the experience in the treatment of infected patients is still limited. Given the lack of specific antiviral drugs, multi-organ function support treatment is important for patients with COVID-19. To improve the cure rate and reduce the mortality of patients with severe- and critical-type COVID-19, this paper summarizes the experience of organ function support in patients with severe- and critical-type COVID-19 in Optical Valley Branch of Tongji Hospital, Wuhan, China. This paper systematically summarizes the procedures of functional support therapies for multiple organs and systems, including respiratory, circulatory, renal, hepatic, and hematological systems, among patients with severe- and critical-type COVID-19. This paper provides a clinical reference and a new strategy for the optimal treatment of COVID-19 worldwide.
