Background: Peripherally inserted central catheters (PICCs) are safe and useful alternatives to centrally inserted central catheters (CICCs). Several studies have investigated the effectiveness and safety of PICCs; however, few have focused on their use in patients with gastroenterological diseases. In the present study, we evaluated the outcomes of patients with gastroenterological diseases who received PICCs and identified the risk factors associated with central line-associated blood stream infection (CLABSI).
Methods: We retrospectively examined hospitalized patients at our institution who received PICCs between 2015 and 2023. We evaluated the data on their clinical characteristics, complications, and outcomes. Furthermore, we investigated the risk factors for CLABSIs.
Results: A total of 405 patients were included (262 men and 143 women). The median age was 71 (range, 15-94) years. The vessels were inserted in the basilic, cephalic, and brachial veins in 366 (90%), 22 (6%), and 17 (4%) patients, respectively. The median procedure time was 32 [6-149] min. The median dwell time was 16 [0-188] days. CLABSI, catheter occlusions, phlebitis, and exit-site skin infection occurred in 14 (3.5%; 1.77/1000 catheter days), 6 (1.5%; 0.76/1000 catheter days), 3 (0.7%; 0.38/1000 catheter days), and 1 (0.2%; 0.13/1000 catheter days) patients, respectively. There was no case of deep vein thrombosis or pulmonary thrombosis due to PICC placement. Multivariate analysis performed using a Cox's proportional hazard regression model revealed that patients with gastroenterological malignancies had an independently higher risk for CLABSIs (odds ratio [OR]: 3.25, 95% confidence interval [CI]: 1.05-10.05, = 0.041) and that older age (⩾70 years) tended to be associated with CLABSIs (OR: 3.61, 95% CI: 0.98-13.32, = 0.054).
Conclusions: Gastroenterological malignancies and older age were associated with a higher risk of CLABSIs. Rigorous catheter management is crucial for preventing complications, particularly in vulnerable patient subgroups.

Purpose: Gastric cancer (GC) remains a major malignancy. Robotic gastrectomy (RG) has gained popularity due to various advantages. Despite those advantages, many hospitals lack the necessary equipment for RG and are still performing laparoscopic gastrectomy (LG) due to its established minimal invasiveness and safety.

Background: Despite accumulating evidence and recommendations for management of colonic diverticular bleeding (CDB), the changes in its clinical management and outcomes remain unknown.
Methods: We performed a retrospective tendency analysis on a biennial basis, a propensity score-matched cohort study between the first and latter half groups, and mediation analyses to compare the diagnostic and treatment methods between January 2010 and December 2019 (CODE BLUE-J Study).
Results: A total of 6575 patients with CDB were included.

DNA methylation is known to be involved in tumor progression. This is the first study to perform an extensive methylation analysis of plasma circulating tumor DNA (ctDNA) using targeted bisulfite sequencing in gastric cancer (GC) patients to evaluate the usefulness of ctDNA methylation as a new biomarker. Sixteen patients who received chemotherapy for recurrent GC were included.

Background/objectives: Positive pancreatic juice cytology (PJC) is an important finding when considering surgical resection in patients with intraductal papillary mucinous neoplasm (IPMN); however, guidelines do not recommend endoscopic retrograde cholangiopancreatography (ERCP) for PJC. This study aimed to clarify the findings worthy of adding PJC for diagnosing high-grade dysplasia (HGD) and invasive carcinoma (IC) in patients with IPMN.
Methods: Patients with IPMN who underwent preoperative PJC and surgical resection at Hiroshima University Hospital were enrolled, and the diagnostic yield of malignant IPMN based on PJC and clinical and imaging findings and the incidence of post-ERCP pancreatitis (PEP) were retrospectively analyzed.

Background/aim: The development of new biomarkers to predict cancer patient prognosis is expected to aid in treatment selection, contributing to improved outcomes. In this study, we extracted a candidate gene associated with patient prognosis from a public database and investigated the molecular and biological functions and clinical significance of the gene in gastric cancer.
Materials And Methods: We analyzed The Cancer Genome Atlas database and identified the family with sequence similarity 32 member a (FAM32A) as a candidate gene.
