Idiopathic myointimal hyperplasia of the mesenteric veins affecting the small intestine alone: A case report and review of literature.

Background: Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare disease characterized by narrowing of the lumen caused by mesenteric vein intimal hyperplasia, resulting in chronic intestinal ischemia. Although the colorectum is the primary site affected by this condition, involvement of the small intestine is even more rare. Recurrence of IMHMV after surgical resection of the affected bowel is uncommon.

Role of gut microbiota in Crohn's disease pathogenesis: Insights from fecal microbiota transplantation in mouse model.

Background: Inflammatory bowel disease, particularly Crohn's disease (CD), has been associated with alterations in mesenteric adipose tissue (MAT) and the phenomenon termed "creeping fat". Histopathological evaluations showed that MAT and intestinal tissues were significantly altered in patients with CD, with these tissues characterized by inflammation and fibrosis.

Aim: To evaluate the complex interplay among MAT, creeping fat, inflammation, and gut microbiota in CD.

Surgical management of duodenal Crohn's disease.

Background: The case of Crohn's disease involving the duodenum is rare, and its surgical management requires a thorough understanding.

Aim: To investigate the surgical management of duodenal Crohn's disease.

Methods: We systematically reviewed patients diagnosed with duodenal Crohn's disease who underwent surgery in the Department of Geriatrics Surgery of the Second Xiangya Hospital of Central South University from January 1, 2004, to August 31, 2022.
