Novel Dynamic Organ Storage System Enhances Liver Graft Function in a Porcine Donation After Circulatory Death Model.

Donation after circulatory death (DCD) livers face increased risks of critical complications when preserved with static cold storage (SCS). Although machine perfusion (MP) may mitigate these risks, its cost and logistical complexity limit widespread application. We developed the Dynamic Organ Storage System (DOSS), which delivers oxygenated perfusate at 10°C with minimal electrical power requirement and allows real-time effluent sampling in a portable cooler.

Change and predictors of body composition after gastrectomy for gastric cancer during first postoperative year.

Purpose: After gastrectomy for gastric cancer, patients often lose significant body weight because of decreased caloric intake and nutrient absorption. Body weight typically requires approximately 1 year to stabilize. This study aimed to examine the changes and predictors of body composition during the first postoperative year.

Finding the Right Hepatic Artery Branching from the Gastroduodenal Artery in a Patient Undergoing Gastrectomy: A Rare Case of an Anatomical Variant.

Numerous vascular anomalies of the hepatic artery have been reported. Protection of the hepatic arterial supply is important during gastrectomy. We herein report a case in which an anatomical variant of the hepatic artery was discovered in a patient undergoing laparoscopic distal gastrectomy with D1+ lymph node dissection for early gastric cancer.

Impact of Lymphocyte/Monocyte Ratio on Outcomes in Patients with Remnant Gastric Cancer After Gastrectomy.

Background: The inflammatory response plays a crucial role in tumor development. Inflammatory markers are recognized prognostic factors in many types of cancer, including gastric cancer. However, the correlation between inflammatory markers and prognosis in remnant gastric cancer (RGC) remains unclear.

Plasma and urinary CP I and CP III concentrations in chimeric mice with human hepatocytes after rifampicin administration.

The interest in transporter-mediated drug interactions has been increasing in the field of drug development. In this study, we measured the plasma and urinary concentrations of coproporphyrin (CP) I and CP III as endogenous substrates for organic anion-transporting polypeptide (OATP) using chimeric mice with human hepatocytes (PXB mice) and examined the influence of an OATP inhibitor, rifampicin (RIF). CP I and CP III were actively taken up intracellularly, and RIF inhibited the uptake in a concentration-dependent manner for both CP I and CP III in human hepatocytes (PXB-cells).

Spontaneous Mediastinal Gastric Perforation in Hiatal Hernia with Difficult Surgical Technique Selection: A Case Report.

Emergency surgery for a hiatal hernia (HH) is uncommon. However, mediastinal gastric perforation may occasionally present as the initial symptom of HH and demonstrate high mortality rates.

Preoperative Osteopenia as Risk Factor for Death from Other Diseases After Gastrectomy in Elderly Patients.

Background/aim: Preoperative osteopenia, defined as low bone mineral density, is a prognostic factor in patients with digestive tract cancers, including gastric cancer (GC). However, the correlation between preoperative osteopenia and GC in elderly patients is unclear.

Patients And Methods: We enrolled 251 patients who had undergone curative surgery for histopathologically diagnosed gastric adenocarcinoma from January 2008 to December 2012.

Hepatectomy for massive hepatic necrosis after transcatheter arterial embolization hemostasis for hepatic hemorrhage following hepatic trauma: A case report.

Key Clinical Message: Although partial hepatic necrosis often occurs following endovascular treatment for bleeding associated with hepatic trauma, it is relatively rare that additional treatment is required. However, invasive procedures such as hepatic resection should sometimes be considered when infection occurs over massive hepatic necrosis.

Abstract: Although partial hepatic necrosis following endovascular treatment for bleeding associated with hepatic trauma is occasionally experienced, it is relatively rare for the necrotic area of the liver to require additional treatment.

Surgical Outcomes of Robotic Distal Pancreatectomy Versus Laparoscopic Distal Pancreatectomy at a Hospital in a Sparsely Populated Area.

Background: Robotic distal pancreatectomy (RDP) has a better or comparable surgical outcome when compared with laparoscopic distal pancreatectomy (LDP). However, whether the surgical outcome for these procedures in local, low-volume hospitals are comparable with those of the typically larger centers described in published reports remains unclear.

Methods: This study enrolled 48 patients who underwent either RDP or LDP between August 2012 and April 2023.

Preoperative low skeletal muscle volume can result in insufficient administration of S-1 adjuvant chemotherapy in older patients with stage II/III gastric cancer.

Background And Purpose: Older patients are more likely to encounter difficulties receiving chemotherapy, but the factors involved in the continuation of chemotherapy in these patients remain unclear. We investigated the importance of muscle mass as a factor involved in delivering a sufficient dose of postoperative S-1 adjuvant chemotherapy (ACT) to older patients with gastric cancer.

Methods: The subjects of this study were 79 patients aged ≥ 65 years with stage II/III gastric adenocarcinoma, who underwent curative gastrectomy and received S-1 ACT.
