Intestinal Obstruction I: Introduction01:29

Intestinal Obstruction I: Introduction

Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...
Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

Begin by inspecting the perianal and anal areas for color, texture, rashes,...
Appendicitis01:19

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
Pyloric Obstruction01:11

Pyloric Obstruction

Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
Inflammatory Bowel Disease V: Surgical Management01:21

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:

Summary
This summary is machine-generated.

A rare case of intestinal obstruction caused by diffuse B-cell Non-Hodgkin's lymphoma of the terminal ileum is presented. Early high-resolution imaging is crucial for diagnosing such uncommon obstructive lesions in patients with prior surgery.

Area of Science:

  • Gastroenterology
  • Oncology
  • Radiology

Background:

  • Post-surgical adhesive small bowel obstruction is common.
  • Obstructive lesions in patients with a history of laparotomy are uncommon.

Observation:

  • A 58-year-old man presented with acute small bowel obstruction.
  • Computed tomography (CT) revealed an ileocecal mass.
  • Histology confirmed diffuse B-cell Non-Hodgkin's lymphoma of the terminal ileum.

Findings:

  • Diffuse B-cell Non-Hodgkin's lymphoma can present as an obstructive intestinal mass.
  • This is an uncommon cause of small bowel obstruction, especially in patients with prior abdominal surgery.

Implications:

  • Early high-resolution imaging, such as CT, can aid in the diagnosis of rare obstructive intestinal lesions.
  • Accurate diagnosis facilitates timely and appropriate clinical management, potentially improving patient outcomes.
