This case report presents a rare occurrence of Sarcina ventriculi in a 15-year-old male patient with a clinical history of renal failure due to chronic rejection status post kidney transplantation, with persistent symptoms of diarrhea, nausea, vomiting, and fatigue. Despite exhibiting normal gastrointestinal mucosa upon endoscopy, biopsy analysis revealed chronic gastritis accompanied by the presence of Sarcina ventriculi in a tetrad arrangement across the stomach, duodenum, and distal esophagus. Interestingly, immunohistochemistry (IHC) staining targeting the Helicobacter pylori organism (H.

Ophir Loyola Hospital, Belém, Pará, 66063-240, Brazil.
Background And Objective: Gastric cancer (GC) remains a leading cause of morbidity and mortality worldwide. The current standard of care involves neoadjuvant chemotherapy (NACT) followed by radical gastrectomy. This study aims to evaluate the efficacy of neoadjuvant therapy with PD-1/PD-L1 inhibitors in comparison to chemotherapy alone for patients with locally advanced gastric cancer (LAGC).

To compare minimally invasive surgery with traditional open surgery, analyze the current application status of health economic evaluations in the treatment of digestive tract cancers, such as esophageal cancer, gastric cancer, and colorectal cancer by minimally invasive surgery and provide evidence for the rational selection of clinical treatment, alleviation of disease-related economic burdens, and rational allocation of healthcare resources. By using five databases, i.e.

Proximal gastrectomy (PG) has reemerged as a viable surgical option for managing proximal gastric cancer and gastroesophageal junction cancer, particularly for early-stage tumors, offering potential advantages over total gastrectomy (TG). This review examines the evolution of PG, emphasizing surgical techniques and outcomes. Although PG was initially abandoned due to postoperative complications such as reflux esophagitis, advances in reconstruction methods, such as the double-flap technique and double-tract reconstruction, have significantly improved patient quality of life and reduced complications.

Combining chemotherapy with immune checkpoint inhibitors (ICIs) that target the programmed death-1 (PD-1) protein has been shown to be a clinically effective first-line treatment for human epidermal growth factor receptor 2 (HER2)-negative and -positive advanced or metastatic gastric cancer (GC). Currently, PD-1 inhibitors combined with chemotherapy are the standard treatment for patients with HER2-negative/positive locally advanced or metastatic GC. Programmed death-ligand 1 (PD-L1) expression, as assessed using immunohistochemistry (IHC), is a crucial biomarker for predicting response to anti-PD-1/PD-L1 agents in various solid tumors, including GC.
