Albumin-Butyrylcholinesterase as a Novel Prognostic Biomarker for Hepatocellular Carcinoma Post-hepatectomy: A Retrospective Cohort Study with the Hiroshima Surgical Study Group of Clinical Oncology.

Background: This study aimed to investigate the association between a new biomarker that incorporates albumin (Alb) and butyrylcholinesterase (BCHE) levels, as well as the prognosis of hepatocellular carcinoma (HCC) after hepatectomy.

Methods: The study enrolled 1712 patients who underwent primary hepatectomy for HCC between January 2003 and December 2019 at seven institutions belonging to the Hiroshima Surgical Study Group of Clinical Oncology. The entire dataset was randomly split into discovery and validation cohorts in a 7:3 ratio.

Different post-pancreatectomy glucagon responses to a meal test between surgical approaches.

Residual pancreatic endocrine function is important for maintaining metabolic status after pancreatectomy and is closely related to patient nutritional status and prognosis. In contrast to insulin secretion, the significance of glucagon secretion following pancreatectomy remains unclear. In this study, we assessed the changes in pancreatic glucagon secretion during pancreatectomy to determine their pathophysiological significance.

This study explored postoperative outcomes and developed a preoperative predictive formula to identify patients most likely to benefit from liver resection.

Spontaneous rupture of the umbilical vein associated with liver cirrhosis: A case report.

Introduction: A decompensated cirrhosis sometimes develops collateral circulation due to severe fibrosis. Rupture of this collateral circulation can induce a fatal situation.

Case Presentation: A 59-year-old man with alcoholic cirrhosis was admitted to our emergency department with a chief complaint of impaired consciousness.

How to do it: endovascular stent and ligament resection during pancreaticoduodenectomy for coeliac axis stenosis in median arcuate ligament syndrome.

To decrease complications associated with the treatment of coeliac axis (CA) stenosis due to median arcuate ligament (MAL) syndrome in pancreaticoduodenectomy, we performed combined preoperative endovascular stenting and intraoperative MAL resection. This technique can secure the CA blood flow to the hepatic artery before surgery in one stage and prevent CA restenosis and stent dislocation because there is no extrinsic compression of the CA after MAL resection.

A multicenter randomized controlled trial comparing administration of antithrombin III after liver resection (HiSCO-05 trial).

Background: Posthepatectomy liver failure is a poor prognostic factor after hepatectomy. Various preventive treatments have been tried; however, there are no clinical trials that use posthepatectomy liver failure as the primary endpoint, and the clinical effects of posthepatectomy liver failure have not been fully verified. The aim of this study was to investigate whether administration of antithrombin III can prevent posthepatectomy liver failure in patients with coagulopathy after hepatectomy.

Long-term outcomes of laparoscopic surgery in elderly patients with colorectal cancer: A single institutional matched case-control study.

Introduction: The number of elderly patients with colorectal cancer has gradually increased. Laparoscopic colorectal surgery is widely used to approach colorectal cancer. The aim of this study was to evaluate long-term outcomes in octogenarians who underwent laparoscopic colorectal surgery for colorectal cancer.

Association between skeletal muscle loss and the response to nivolumab immunotherapy in advanced gastric cancer patients.

Background: Skeletal muscle loss is a hallmark of malignancies, including advanced gastric cancer (GC). Although programmed death (PD)-1 inhibitors, including nivolumab, have promising anti-cancer effects, there is limited information regarding markers that can predict these therapeutic effects, which include PD-ligand 1 (PD-L1) expression and the tumor mutation burden. Therefore, we evaluated whether the baseline psoas muscle mass index (PMI, a surrogate for skeletal muscle mass) could predict the response of GC to nivolumab treatment, based on progression-free survival (PFS), the objective response rate, and the disease control rate.
