Methods: In this study, 264 patients who underwent PD for pancreatic head cancer between 2011 and 2021 were retrospectively analyzed. The patients were subsequently categorized into three groups according to the estimated glomerular filtration rate: normal group (> 90 mL/min/1.

Development and validation of a predictive model for in-hospital mortality from perioperative bacteremia in gastrointestinal surgery.

Purpose: Prognostic scores require fluctuating values, such as respiratory rate, which are unsuitable for retrospective auditing. Therefore, this study aimed to develop and validate a predictive model for in-hospital mortality associated with gastrointestinal surgery for retrospective auditing.

Methods: Data from patients with bacteremia related to gastrointestinal surgery performed at Shizuoka General Hospital between July 2006 and December 2021 were extracted from a prospectively maintained database.

Systemic inflammation score as a predictor of death within one year after esophagectomy.

Background: After radical resection for esophageal cancer, death within 1 year of surgery can occur due both to recurrence and to other diseases, even after postoperative complications have been overcome. This study identified risk factors for early death within 1 year of esophagectomy for reasons other than death in hospital in patients undergoing esophagectomy for esophageal cancer or esophagogastric junction cancer.

Methods: We reviewed 366 patients who underwent esophagectomy without adjuvant treatment between January 2009 and July 2022 for thoracic esophageal cancer or esophagogastric junction cancer.

Repair of Bile Duct Injury Using Indocyanine Green Following Laparoscopic Cholecystectomy.

Bile duct injury (BDI) is a potential complication that may arise during cholecystectomy and continues to occur with a certain frequency in the present day. Numerous reports have been published regarding the utilization of indocyanine green (ICG) for the prevention of biliary injury, and we feel that the importance of ICG is being recognized. In this context, we present a case wherein a BDI occurred following cholecystectomy, and ICG was employed for the safe repair of the biliary tract.

Effect of Ga substitution with Al in ZSM-5 zeolite in methanethiol-to-hydrocarbon conversion.

The catalytic properties of conventional H-[Al]-ZSM-5 and gallium-substituted H-[Ga]-ZSM-5 were evaluated in the conversion of methanethiol to ethylene (CHSH → 1/2CH + HS). Dimethyl sulfide (DMS), aromatics, and CH were formed as byproducts on the H-[Al]-ZSM-5 catalyst. The introduction of Ga into the ZSM-5 structure provided a high ethylene yield with relatively high selectivity for olefins.

Risk factors for gallstone disease onset in Japan: Findings from the Shizuoka Study, a population-based cohort study.

In the research literature on factors associated with gallstones, large population-based cohort studies are rare. We carried out a study of this type to explore risk factors for the onset of gallstones. This study included Japanese participants aged 40-107 years who were followed prospectively from January 2012 to September 2020 using a dataset composed of two individually linked databases, one containing annual health checkup records and the other containing medical claims for beneficiaries of the National Health Insurance System and the Medical Care System for Elderly in the Latter Stage of Life in Shizuoka Prefecture, Japan.

The impact of the American Society of Anesthesiology-Physical Status classification system on the treatment and prognosis of patients with esophageal cancer undergoing esophagectomy.

Background: The American Society of Anesthesiologists-Physical Status (ASA-PS) classification system has been shown to predict morbidity and mortality after surgery. However, the impact of the ASA-PS on esophageal cancer treatment remains unclear. This study examined both the impact of the ASA-PS on treatment, including surgery and perioperative chemotherapy, and the prognostic effects of ASA-PS class in patients who had undergone esophagectomy for thoracic esophageal cancer or esophagogastric junction cancer.

Preoperative skeletal muscle index and visceral-to-subcutaneous fat area ratio are associated with long-term outcomes of elderly gastric cancer patients after gastrectomy.

Purpose: Sarcopenia is a risk factor of severe surgical complications, short-term outcomes, and long-term outcomes for patients with gastric cancer. Several computed tomography (CT) measurements have been performed to diagnose sarcopenia. However, the optimal CT measurements for determining long-term outcomes have not been revealed.

Structural insight into the substrate specificity of Bombyx mori β-fructofuranosidase belonging to the glycoside hydrolase family 32.

Sucrose-hydrolyzing enzymes are largely divided into β-fructofuranosidase and sucrose α-glucosidase. The domestic silkworm Bombyx mori possesses both enzymes, BmSUC1 and BmSUH, belonging to the glycoside hydrolase family 32 (GH32) and GH13, respectively. BmSUC1 was presumed to be acquired by horizontal gene transfer from bacteria based on phylogenetic analysis and related to tolerance to sugar-mimic alkaloids contained in mulberry latex.

Hand-assisted robotic surgery in the abdominal phase of robot-assisted oesophagectomy.

Robot-assisted minimally invasive oesophagectomy (RAMIE) has been developed to overcome the technical limitations of conventional thoracoscopic oesophagectomy. Hand-assisted laparoscopic surgery (HALS) is used as a practical and useful technique during the abdominal phase of thoracoscopic oesophagectomy. During RAMIE, a robotic vessel sealer cannot be used with HALS; another vessel sealer or ultrasonic coagulating device for laparoscopic surgery is required.

Duplicate left gastric artery identified during laparoscopic distal gastrectomy.

The reported incidence of duplicate left gastric artery is not very low, with a rate of 0.4%. However, there have been no reports of the surgical management of patients with a duplicate left gastric artery.

Size of the thoracic inlet predicts cervical anastomotic leak after retrosternal reconstruction after esophagectomy for esophageal cancer.

Background: Although an anastomotic leak after esophagectomy is one of the most common postoperative complications, it is not well understood whether specific anatomic factors of the different route of reconstruction can predispose to the development of anastomotic leak after esophagectomy. This study aimed to clarify whether various factors related to the size of the thoracic inlet are independent predictors of anastomotic leak after esophagectomy.

Methods: We reviewed 248 patients who underwent esophagectomy with retrosternal reconstruction of the gastric conduit between January 2013 and March 2019.

Emergency laparoscopic cholecystectomy for intraabdominal hemorrhage in a patient with a left ventricular assist device: a case report.

Background: Continuous-flow left ventricular assist devices (LVADs), called "second generation LVADs," have significantly improved the survival and quality of life outcomes. Accordingly, non-cardiac surgery in a patient with LVADs has required for conditions not directly related to their LVADs. And the management of bleeding in non-cardiac site remains one of long-term critical topics.
