Inflammatory Bowel Disease V: Surgical Management

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:

Histology of the Small Intestine

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...

Esophageal Perforation-II: Clinical Manifestations and Management

Esophageal Perforation-II: Clinical Manifestations and Management

Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
Clinical Manifestations:

Esophageal Strictures-II: Clinical Features and Management

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Inflammatory Bowel Disease II: Crohn's Disease

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Summary

Jejunal diverticulosis, outpouchings of the small bowel, can rarely cause a closed loop obstruction with small intestinal volvulus. Prompt surgical intervention is crucial for these rare but serious conditions.

Area of Science:

Gastroenterology
Surgical Gastroenterology

Background:

Jejunal diverticulosis involves outpouchings of the small bowel's mucosa and submucosa.
These diverticula are often asymptomatic but can lead to intestinal obstruction.

Observation:

A case report details an 84-year-old male with abdominal pain and weakness.
Preoperative CT scan revealed a closed loop small bowel obstruction with mesenteric swirling.

Findings:

Diagnostic laparoscopy identified extensive proximal jejunal diverticulosis and volvulus.
Surgical intervention included detorsion, resection of the affected jejunum, and primary anastomosis.

Implications:

Concurrent jejunal diverticulosis and small intestinal volvulus are exceedingly rare.
Closed loop small bowel obstruction necessitates urgent surgical management to prevent ischemia, perforation, and sepsis.
