Methods: We performed a cross-sectional analysis (total n = 108,446).

Laparoscopic-Assisted Resection for an Extra-gastrointestinal Stromal Tumor Arising From the Mesentery of the Small Intestine: A Case Report.

Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors that arise in the muscular or submucosal layers of the gastrointestinal tract. Extra-gastrointestinal stromal tumors (EGISTs) are rare primary entities that develop outside the digestive tract which are histologically and immunologically similar to GISTs. We present the case of a 52-year-old female diagnosed with a primary EGIST arising in the small bowel mesentery four months after undergoing hormone therapy for multiple uterine myomas.

Hepatic inflammation and fibrosis are profiles related to mid-term mortality in biopsy-proven MASLD: A multicenter study in Japan.

Methods: We enrolled 1349 patients with biopsy-proven MASLD.

Risk factors for remnant gastric cancer after distal gastrectomy for gastric cancer: a retrospective database review.

Background: The number of patients with remnant gastric cancer (RGC) following gastrectomy for gastric cancer (GC) is increasing due to the increasing number of patients undergoing function-preserving gastrectomy and improved outcomes for patients with GC. A few studies involving a small number of cases reported male sex, old age, differentiated type, tumor depth and synchronous multiple GC were associated with RGC development. However, the risk factors for RGC development had not been fully understood.

Noninvasive tests predict liver-related events and mortality in patients with nonalcoholic fatty liver disease: sub-analysis of the CLIONE-Asia study.

Background And Aims: Noninvasive tests (NITs) have prognostic potential, but whether NITs are comparable with liver biopsy is unclear. This study aimed to examine the prognostic accuracy of NITs for liver-related mortality (LRM) and events (LREs) in patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD).

Methods: We investigated 1313 patients with NAFLD.

Fatal acquired coagulation factor V deficiency after hepatectomy for advanced hepatocellular carcinoma as a possible immune checkpoint inhibitor-related adverse event: a case report.

Background: Atezolizumab plus bevacizumab therapy was recently introduced as the first line for unresectable advanced hepatocellular carcinoma (HCC), but immune-related adverse events (IrAEs) due to atezolizumab are a great concern. Here, we report the case of a patient who developed fatal acquired coagulation factor deficiency after hepatectomy for HCC, treated with atezolizumab and bevacizumab before surgery.

Case Presentation: A 70-year-old man received right trisegmentectomy of the liver with hepaticojejunostomy for advanced HCC with bile duct invasion, after atezolizumab and bevacizumab therapy.

Transmission dynamics of SARS-CoV-2 on the Diamond Princess uncovered using viral genome sequence analysis.

An outbreak of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) occurred aboard the Diamond Princess cruise ship between her January 20 departure and late February 2020. Here, we used phylodynamic analyses to investigate the transmission dynamics of SARS-CoV-2 during the outbreak. Using a Bayesian coalescent-based method, the estimated mean nucleotide substitution rate of 240 SARS-CoV-2 whole-genome sequences was approximately 7.

Cecal cancer with essential thrombocythemia treated by laparoscopic ileocecal resection: a case report.

Background: Essential thrombocythemia (ET) is a myeloproliferative disorder characterized by thrombocytosis and a propensity for both thrombotic and hemorrhagic events. ET rarely occurs simultaneously with colorectal cancer. Here, we report a case of colorectal cancer in an ET patient treated using laparoscopic ileocecal resection.

Predictors of hepatocellular carcinoma recurrence associated with the use of direct-acting antiviral agent therapy for hepatitis C virus after curative treatment: A prospective multicenter cohort study.

Background: Previous studies have suggested an association between the use of direct-acting antiviral agents (DAAs) for treating hepatitis C virus (HCV) infection and the resulting decrease in the incidence of hepatocellular carcinoma (HCC); however, it is unclear whether DAAs prevent the recurrence of HCC after curative treatment for HCC. This study aimed to prospectively investigate HCC recurrence and its predictors after curative treatment for HCC.

Methods: A total of 3012 patients with chronic HCV infection, with or without cirrhosis, who were treated with DAAs were enrolled between January 1, 2015 and January 31, 2017 as per the institutional review board approved study protocol at 15 institutions, including 10 university hospitals and five high-volume centers in the Kyusyu area of Japan.

[Portal venous stent placement for variceal hemorrhage in the elevated jejunum caused by portal vein stenosis after pancreatoduodenectomy:a case report].

An 86-year-old male underwent pancreatoduodenectomy with resection and reconstruction of portal vein for pancreatic cancer. He was admitted to our hospital because of severe anemia and dyspnea ten months later. Computed tomography showed varices at the biliary-enteric anastomosis in the elevated jejunum caused by portal venous stenosis, which was suspected as the cause of anemia.

Direct-acting antiviral agents do not increase the incidence of hepatocellular carcinoma development: a prospective, multicenter study.

Background: While achieving sustained virological response (SVR) following interferon-based or direct-acting antiviral agent (DAA) treatments reduces the incidence of hepatocellular carcinoma (HCC), an increase in unexpected early occurrence or recurrence of HCC after hepatitis C virus elimination by DAA treatments has been reported. We prospectively investigated the incidence and risk factors of HCC after DAA treatment in a large multicenter cohort in Japan.

Methods: Patients with chronic hepatitis C with or without cirrhosis who were treated with DAAs and obtained SVR were enrolled.

[A Case of Resection of Advanced Pancreatic Adenosquamous Carcinoma in which Multidisciplinary Treatment Was Effective].

A 72-year-old man with general fatigue was referred, and CT and MRI revealed a pancreatic mass with necrosis that was suspected of invading the stomach, splenic artery, celiac artery, liver, and portal vein. Upper gastrointestinal endoscopy showed an extrinsic mass with ulcer formation in the posterior wall of the upper gastric corpus and irregular mucosa in the lower esophagus incidentally. Biopsy showed squamous cell carcinoma from both lesions, leading to the diagnosis of pancreatic adenosquamous carcinoma and early esophageal cancer.
