    Pancreatic cancer is known to have the poorest prognosis among digestive cancers. With the development of new chemotherapeutic agents and introduction of multidisciplinary therapy, however, the treatment outcomes for pancreatic cancer have dramatically improved over the past two decades. The keys to successful treatment will be accurate assessment of resectability [resectable (R), borderline resectable (BR) or unresectable (UR)] at the time of diagnosis and prompt adoption of an appropriate multidisciplinary treatment strategy. Prep-02/JSAP-05 trial which is an RCT of upfront surgery versus neoadjuvant chemotherapy using GEM and S-1 (GS) and subsequent surgery for R-PDAC in Japan indicated neoadjuvant chemotherapy had a longer overall survival (OS) than those undergoing upfront surgery (36.7M vs. 26.6M, p = 0.015). In a retrospective multicenter study in Japan reported that in BR-PDAC, median survival time (MST) in the pretreatment group was significantly better than that in the upfront surgery group (25.7 months vs. 19.0 months, p = 0.015) according to a propensity score matching analysis. Another retrospective multicenter study with UR-LA PDAC in Japan reported that conversion surgery was more beneficial for patients with more than 8 months of preoperative therapy than those with less than 8 months of that therapy. Various clinical trials on pancreatic cancer are ongoing, and the results of trials on chemotherapeutic regimens and multidisciplinary treatments will be of further interest.

    Hepatocellular carcinoma (HCC) is one of the most common cancers in the world, and cirrhosis is a risk factor for HCC. Resection is indicated for those unilobar tumors without vascular invasion and metastases in the liver and preserved liver function. Small HCC (< 2 cm) without microvascular invasion is associated with a 5-year recurrence rate as high as 50% to 60%, whereas liver transplantation is indicated for those within the Milan criteria (solitary tumor ≤ 5 cm or two or three nodules ≤ 3 cm) who have decompensated cirrhosis. The 1-, 3-, and 5-year survival rates of living donor liver transplantation for HCC are 85%, 75%, and 70%, respectively. This review summarizes the scientific evidence supporting the clinical practice recommendations for patients with HCC, and it discusses surgical treatment of HCC.

    Hepatocellular carcinoma (HCC) is a common malignant tumor with a high morbidity and mortality in China and elsewhere in the world. Due to its tumor heterogeneity and distant metastasis, patients with HCC often have a poor prognosis. A surgical treatment such as a radical hepatectomy is still the treatment of choice for patients with HCC in current clinical practice. However, the high rate of recurrence and rate of metastasis after surgery diminishes the survival of and prognosis for these patients. In an era of targeted therapy and immunotherapy, the surgical treatment of HCC must change. This review focuses on the definition, feasibility, and criteria with which to evaluate neoadjuvant therapy for HCC in order to provide a new perspective on surgical treatment of HCC.

    Portal vein tumor thrombus (PVTT) is one of the most common complications of hepatocellular carcinoma (HCC), which refers to the advanced stage of HCC and indicates an extremely poor prognosis. Monotherapy cannot effectively prolong the survival benefit of patients with HCC-PVTT characterized by a high recurrence rate. With great progress in the area of immune and molecular targeted therapy, there comes a promising era of multidisciplinary management of HCC. Survival benefits can be achieved based on accurate diagnosis, staging, and multidisciplinary management. Additionally, in terms of the presence of controversy about the standard treatment algorithm and the absence of universal treatment guidelines, a multidisciplinary management program may afford the best hope for HCC-PVTT patients via appropriate implement of various treatment protocols.

    The preferred treatment for hepatocellular carcinoma (HCC) is surgery, which is the only way to achieve long-term survival and even a cure. However, the vast majority of patients with liver cancer in China are already in the middle to advanced stage of the disease and no longer have the opportunity to undergo surgery. The goal of conversion therapy is to transform unresectable advanced liver cancer or potentially resectable liver cancer into resectable cancer, so it has become a topic of interest in the treatment of advanced liver cancer. Common modalities of conversion therapy are: local treatment (TACE, TARE, or HAIC), systemic treatment (targeted therapy alone or combined with immunotherapy), and a therapeutic alliance (TACE combined with radiation therapy, TACE combined with targeted therapy, HAIC combined with targeted therapy, or HAIC combined with targeted therapy and immunotherapy). The plan for maintenance treatment after conversion therapy is determined based on the outcome of conversion therapy to obtain the best survival benefit for patients.

    This study aimed to investigate the value of multidisciplinary team (MDT) management in minimally invasive treatment of complex intrahepatic bile duct stones (IHDs) by laparoscopy, choledochoscopy and percutaneous choledochoscopy. The characteristics, perioperative index, complication rate and minimally invasive rate of patients in MDT group (n = 75) and non-MDT group (n = 70) were compared. The members of MDT include doctors in ultrasound, imaging, hepatobiliary and pancreatic surgery, anaesthesia and intensive care medicine. The results showed that minimally invasive surgery reduced the incidence of postoperative residual stones, OR (95% CI) = 0.365 (0.141-0.940) (p = 0.037). MDT reduced the operation time, OR (95% CI) = 0.406 (0.207-0.796) (p = 0.009). Minimally invasive surgery significantly reduced intraoperative bleeding, OR (95% CI) = 0.267 (0.133-0.534) (p < 0.001). Minimally invasive surgery also reduced hospitalization time, OR (95% CI) = 0.295 (0.142-0.611) (p = 0.001). The stone clearance rates of MDT group and non-MDT group were 81.33% and 81.43% respectively. In the MDT group, the operative time was less than that in the non-MDT group (p = 0.010); the intraoperative bleeding volume was significantly less than that in the non-MDT group (p < 0.001); the hospitalization time was less than that in the non-MDT group (p = 0.001). Minimally invasive operation rate:48 cases (64.00%) in MDT group were significantly higher than 17 cases (24.29%) in non-MDT group (p < 0.001). In conclusion, minimally invasive procedures can be selected more through MDT. MDT can shorten the operation time, and minimally invasive surgery can reduce the incidence of residual stones, reduce intraoperative bleeding, and may shorten hospital stay. Therefore, MDT management model can provide personalized and minimally invasive surgical protocol for patients with complex IHD, which has high application value.

    The incidence of inflammatory bowel disease (IBD) with a poor prognosis is increasing, and a single field is not capable of fully diagnosing and comprehensively treating IBD. The purpose of the current study was to explore the role of a multidisciplinary team (MDT) in the diagnosis and treatment of IBD. Subjects were 55 patients with IBD who underwent surgery at this hospital before the establishment of a MDT (before June 2016) and 276 patients who were discussed by a MDT; 72 of the latter patients underwent surgery. The preoperative rate of diagnosis, preoperative basic nutritional status, frequency of emergency surgery, and surgical complications in the two groups were compared to determine whether the MDT significantly affected the diagnosis and treatment of IBD and to explore trends in the types of patients with IBD and treatment decision-making since the establishment of MDT. Results revealed that the MDT significantly improved preoperative diagnostic accuracy for patients with IBD who underwent surgery (p < 0.005), and the frequency of elective surgery decreased significantly (p < 0.005). There were significant differences in the rate of clinical recurrence (p < 0.005) and the rate of additional surgery (p < 0.01) between the two groups, with higher rates in the control group. In terms of preoperative nutritional status, the proportion of decreased serum albumin and hemoglobin in the experimental group was significantly lower than that in the control group (p < 0.05). MDT plays a positive role in accurate preoperative diagnosis, improvement of preoperative preparations, and a reduction in postoperative adverse events for patients with IBD undergoing surgery.

    Severe acute pancreatitis (SAP) is a common critical disease with a high mortality rate that involves a complex, rapid change in condition and multiple organ systems. Therefore, a multidisciplinary team (MDT), including staff from the emergency department, intensive care unit, pancreatic surgery, gastroenterology , and imaging, is necessary for the early diagnosis, evaluation, and treatment of patients with SAP. This involves managing the systemic inflammatory response and maintaining organ function in the early stage and managing systemic infection and treatment of peripancreatic complications in the middle-to-late stages. The MDT should be led by departments corresponding to the clinical characteristics of each stage, and those departments should be responsible for the coordination and implementation of treatment by other relevant departments. In the late stage, pancreatic surgery and gastroenterology are the main departments that should manage peripancreatic complications. In line with the principle of minimally invasive treatment, the timely and reasonable selection of endoscopic or minimally invasive surgical debridement can achieve good therapeutic outcomes. Open surgery is also an effective method for treating an intractable massive hemorrhage in the abdominal cavity or necrotic cavity, intractable abdominal compartment syndrome, visceral perforation, and fistulae.

    The COVID-19 pandemic continues to ravage the world. As many countries have entered the postpandemic period, current efforts to prevent and control COVID-19 have gradually been normalized in many countries. Although the focus is on vaccines to achieve herd immunity, conventional physical containment strategies should be reassessed as part of efforts to prevent and control infectious diseases. Continued respiratory protective measures such as social distancing and the wearing of masks have been extensively accepted by the public in most countries. A point worth noticing is that the activities of influenza and other respiratory diseases have decreased as these strategies have been implemented. Public mobilization and large-scale campaigns to promote health are also important to interrupting the transmission of pathogens. A good example can be found in the achievements of China's Patriotic Public Health Campaign. These practices underscore the importance of enhancing physical containment strategies and public mobilization and management, with support from the legal system, to respond to any potential emerging infectious diseases.

    The COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in a serious public health burden. As the COVID-19 epidemic in China would coincide with a seasonal outbreak of influenza, there were serious concerns about whether influenza would be aggravated by the SARS-CoV-2 infection and COVID-19 pandemic. This article provides a brief overview of the impacts of the COVID-19 epidemic on influenza activity in China. The percentage of positive influenza tests decreased during the COVID-19 pandemic. During the first stage of the COVID-19 outbreak, the percentage of positive influenza tests reached to a peak of 47.7%. At the second stage, the percentage of positive influenza tests was dramatically decreased from 40.4% to 14.0%. Thereafter, it remains at a low level of less than 6.2%. In addition, the possible causes of this phenomenon have been summarized, including prevention and control measures and ecological competition. Lastly, this article suggests that the public health approach to preventing COVID-19 may also help to control other respiratory infectious diseases. Public health measures need to be maintained even in the later stages of the COVID-19 epidemic.
