Objective: To investigate the factors contributing to the blockage of perfusion tubes during hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with appendiceal pseudomyxoma peritonei (PMP) undergoing combined cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy treatment, and to construct a nomogram for predicting the risk of tube occlusion.
Study Design: Observational study. Place and Duration of the Study: Department of Gastrointestinal Surgery, Central Hospital Affiliated to Shandong First Medical University, Jinan, China, from June 2017 to December 2023.
Methodology: Tube occlusion was defined as the inability to achieve 30 minutes of continuous unobstructed perfusion. Statistical methods such as univariate analysis, multivariate analysis, and Lasso regression were employed for data analysis.
Results: The results revealed that 27% of the 383 hyperthermic intraperitoneal chemotherapy perfusion treatments resulted in the tube occlusion events. Multivariate logistic regression analysis identified age, CA-125, CA19-9, and pathological type as the independent risk factors. A nomogram predicting the tube occlusion was constructed and validated for its predictive accuracy and clinical utility.
Conclusion: This study successfully developed a nomogram to predict the tube occlusion risk during cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy treatment for patients with pseudomyxoma peritonei, providing valuable guidance for clinical practice and aiding in personalised treatment decisions to improve patient prognosis. However, further research is needed to validate the reliability and clinical applicability of the model, as well as to investigate the impact of tube occlusion on treatment outcomes and corresponding management strategies.
Key Words: Pseudomyxoma peritonei, Cytoreductive surgery, Hyperthermic intraperitoneal chemotherapy treatment, Tube occlusion, Nomogram.

Objectives: Surgery is the only treatment for congenital choanal atresia (CCA). It is crucial to avoid postoperative restenosis or re-occlusion of the neo-choana. This study investigated the efficacy of a navigation-assisted endoscopic endonasal U-flap technique and a bioabsorbable steroid-eluting stent for CCA repair.

Objective: Hirudin has shown potential in promoting angiogenesis and providing neuroprotection in ischemic stroke; however, its therapeutic role in promoting cerebrovascular angiogenesis remains unclear. In this study, we aimed to investigate whether hirudin exerts neuroprotective effects by promoting angiogenesis through the regulation of the Wnt/β-catenin signaling pathway.
Methods: An in vitro model of glucose and oxygen deprivation/reperfusion (OGD/R) was established using rat brain microvascular endothelial cells (BMECs).
Evaluation of Pelvic Pathology of Subfertile Women by Transvaginal Sonography and Correlation with Laparoscopic Findings.

Damage of fallopian tube, endometriosis, fibroid uterus, adenomysis and polycystic ovary syndrome are the major pelvic pathology that causes subfertility. Although there are many diagnostic tests available, the clinical presentation of each patient can usually be linked to specific and efficient testing strategies. Transvaginal sonographic (TVS) imaging is an effective, easy to use, safe and readily available noninvasive means to evaluate fertility potential.

Pericardial-esophageal fistula is a rare complication after radiofrequency ablation for atrial fibrillation. A 52-year-old man developed pneumopericardium, which was revealed by echocardiogram and computed tomography, after a combined ablation and left atrial appendage occlusion procedure for atrial fibrillation. He was diagnosed with a pericardial-esophageal fistula and underwent surgical pericardial and mediastinal drainage tube placement.

Clinical Relevance: Endonasal dacryocystorhinostomy (EN-DCR) is one of the preferred interventions for occlusion of the nasolacrimal drainage system. Understanding the bulbar conjunctival changes that occur after EN-DCR surgery will provide better insight into the effect of this procedure on visual quality and patient comfort.
Background: This study aimed to evaluate visual quality and bulbar conjunctival cytologic changes using in vivo confocal microscopy and corneal topography in patients with epiphora resulting from nasolacrimal duct obstruction after EN-DCR.
