Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

2
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...

Intestinal Obstruction I: Introduction01:29

Intestinal Obstruction I: Introduction

2
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,...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.2K
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Diverticular Disease of the Colon01:27

Diverticular Disease of the Colon

2
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...

Pyloric Obstruction01:11

Pyloric Obstruction

2
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...

Esophageal Varices-I: Introduction01:24

Esophageal Varices-I: Introduction

2.3K
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Summary
This summary is machine-generated.

Sigmoid volvulus (SV) involves colon twisting, causing obstruction. Endoscopic detorsion is primary, but surgery is vital for complications, with resection and anastomosis being common procedures.

Area of Science:

  • Gastroenterology
  • Surgical Gastroenterology
  • Abdominal Imaging

Background:

  • Sigmoid volvulus (SV) is a significant cause of large bowel obstruction, ranging from 2% to 50% of all cases.
  • This condition predominantly affects adults, with a higher prevalence in males, and exhibits notable geographic variations.
  • The etiology of SV is complex and debated, presenting with symptoms like abdominal pain, distention, and constipation.

Purpose of the Study:

  • To provide a comprehensive overview of sigmoid volvulus (SV).
  • To detail the diagnostic methods and treatment strategies for SV.
  • To discuss the clinical presentation, etiology, and outcomes associated with SV.

Main Methods:

  • Review of clinical, radiological, and endoscopic findings in SV diagnosis.
  • Analysis of treatment approaches, including endoscopic detorsion and surgical interventions.
  • Evaluation of diagnostic imaging techniques such as X-ray, CT, and MRI.

Main Results:

  • Diagnostic hallmarks include a dilated sigmoid colon on X-ray, a whirled mesentery on CT/MRI, and a spiral mucosal twist on endoscopy.
  • Flexible endoscopic detorsion is the preferred initial treatment, while emergency surgery is indicated for peritonitis, gangrene, perforation, or treatment failure.
  • Resection with primary anastomosis is the most frequent surgical procedure for SV.

Conclusions:

  • SV diagnosis relies on a combination of clinical, radiological, and endoscopic evidence.
  • Endoscopic detorsion is effective, but surgical intervention is crucial for severe cases and complications.
  • Mortality rates for SV range from 10% to 50%, with morbidity between 6% and 24%.
