Background: Gallbladder cancer (GBC) is the most common biliary malignancy frequently metastatic at diagnosis with poor prognosis. While surgery remains the standard for early-stage GBC, the role of surgery in patients with metastatic gastrointestinal cancers is expanding due to improvements in systemic therapies. We sought to evaluate the survival of patients with stage IV GBC undergoing surgery in an era of improved multi-agent systemic therapy.
Methods: A retrospective review of the National Cancer Database was performed. Patients with stage IV GBC who underwent systemic therapy were included. Patients who received radiation therapy, palliative therapy or had missing survival data were excluded. Univariable and multivariable analysis was performed.
Results: 4,145 patients were identified between 2004 and 2016. Mean age was 69. Surgery combined with systemic therapy predicted improved median survival compared with chemotherapy alone (11.1mo versus 6.8mo, HR 0.65, p < 0.001). Additionally, receipt of treatment after 2011 predicted improved survival (HR 0.86, p < 0.001). Patients treated with multi-agent chemotherapy in combination with surgery were associated with the greatest hazard ratio benefit (0.40, p < 0.001) versus single agent therapy alone.
Conclusion: Patients with stage IV gallbladder cancer treated with a combination of surgery and chemotherapy are associated with an improved overall survival compared to chemotherapy alone. Patients receiving care during the more recent era demonstrated improved survival. These results support a role for surgery in selected patients with stage IV gallbladder cancer receiving chemotherapy.

Emodin, as a natural active ingredient, has shown great application potential in the fields of medicine, food and cosmetics due to its unique pharmacological effects, such as anti-inflammatory, antioxidant, anti-cancer, etc. In recent years, with the development of science and technology and the increase of people's demand for natural medicine, emodin research has been paid more and more attention by the global scientific research community. The bibliometric analysis of emodin and the construction of knowledge map are still blank.

Purpose: To compare overall survival (OS), toxicity, and quality of life (QOL) in patients with metastatic gallbladder cancer receiving oral capecitabine (X) with best supportive care (BSC) and BSC alone.
Materials And Methods: Patients with metastatic gallbladder cancer and Karnofsky Performance Status (KPS) ≥70 were accrued and assigned to either arm A or B. Assignment to these two arms was based on physician/patient discretion.

Severe damage to the intrahepatic biliary duct (IHBD) network occurs in multiple human advanced cholangiopathies, such as primary sclerosing cholangitis, biliary atresia and end-stage primary biliary cholangitis. Whether and how a severely damaged IHBD network could reconstruct has remained unclear. Here we show that, although the gallbladder is not directly connected to the IHBD, there is a common hepatic duct (CHD) in between, and severe damage to the IHBD network induces migration of gallbladder smooth muscle cells (SMCs) to coat the CHD in mouse and zebrafish models.

Background: Special attention should be given to intra-abdominal adhesions in patients with a history of open cholecystectomy for gallstones or abdominal surgery. Choosing the appropriate surgical approach to remove the stones is crucial.
Patient Summary: A 68-year-old male was admitted due to sudden onset of upper abdominal pain lasting more than 6 h.
