    The structure of human terminal ileum mucosa was studied both after total colectomy and conventional ileostomy and after total colectomy and ileo-rectal anastomosis. Villous height, gland depth, number of mitoses, relative density of goblet cells and types of mucins secreted were microscopically evaluated in ileal biopsy specimens from 24 patients a minimum 6 months after surgery. Subtotal villous atrophy with glandular hypertrophy was demonstrated after both surgical procedures. The degree of villous atrophy and glandular hypertrophy was not dependent either on the disease for which surgery was performed, nor on the duration of the post-surgical period. Villous atrophy and glandular hypertrophy appeared greater in ileo-rectal anastomosis specimens than in those from ileostomy. Goblet cell density did not seem to be affected by total colectomy. After surgery no changes in the types of mucins secreted were shown by the histochemical techniques employed. This light microscopical study did not provide any evidence of increase ileal absorptive surface after total colectomy.

    Histology of the Small Intestine

    The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
    The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

    Histology of the Large Intestine

    The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
    The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

    Inflammatory Bowel Disease V: Surgical Management

    Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
    Here are some common surgical interventions for IBD:

    Inflammatory Bowel Disease II: Ulcerative Colitis

    Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
