Asymptomatic low-grade appendiceal mucinous neoplasm: A case report.

Background: Low-grade appendiceal neoplasms (LAMN) are characterized by low incidence and atypical clinical presentations, often leading to misdiagnosis as acute or chronic appendicitis before surgery. The primary diagnostic tool for LAMN is abdominal computed tomography (CT) imaging. Surgical resection remains the cornerstone of LAMN management, necessitating en bloc tumor excision to minimize the risk of iatrogenic rupture.

Digestive tract reconstruction after laparoscopic proximal gastrectomy for Gastric cancer: A systematic review.

The incidence of gastroesophageal junction adenocarcinoma has gradually increased. Proximal gastrectomy or total gastrectomy is recommended for early gastric cancer of the upper third of the stomach. Because total gastrectomy is often accompanied by body mass loss and nutrient absorption disorders, such as severe hypoproteinemia and anemia, Proximal gastrectomy is more frequently recommended by researchers for early upper gastric cancer (T1N0M0) and Siewert II gastroesophageal junction cancer less than 4 cm in length.

Hypoxic Tumor-Derived Exosomal miR-199a-3p Promote Gastric Cancer Metastasis via MAP3K4.

Proximal gastrectomy is more frequently recommended for early upper gastric cancer and Siewert II gastroesophageal junction cancer less than 4 cm in length. After proximal gastrectomy, the anatomical structure of the gastroesophageal junction can be destroyed, and the anti-reflux effect of the cardia is lost. In recent years, as various anti-reflux reconstructions have been developed, some functions of the stomach are retained, and serious reflux esophagitis is avoided after proximal gastrectomy.

Cardia function-preserving surgery and anti-reflux anastomotic method after proximal gastrectomy for gastric cancer: Current status and future perspectives.

Radical resection and lymph node dissection is the preferred treatment for gastric cancer. Proximal gastrectomy or total gastrectomy is usually performed for gastroesophageal junction adenocarcinoma and upper gastric cancer.
