Intra-Abdominal Abscess

Overview

Intra‑abdominal abscess is a serious medical condition in which infected fluid and pus accumulate inside the abdominal cavity. These abscesses usually develop as a complication of abdominal infections, surgery, trauma, or rupture of internal organs.

The abscess may form near organs such as the liver, stomach, intestines, pancreas, or pelvis. Without prompt treatment, the infection can spread into the bloodstream and lead to severe complications.

At Moolchand Hospital, patients with abdominal infections receive specialized care from experienced general surgeons, gastroenterologists, and critical care specialists. As a trusted multi super speciality hospital in Delhi and a leading hospital in Lajpat Nagar Delhi, Moolchand provides advanced imaging, minimally invasive drainage procedures, and surgical treatment for complex abdominal infections.

What is an Intra-Abdominal Abscess?

An intra-abdominal abscess is a localized pocket of pus inside the abdominal cavity. The body sometimes forms an abscess to isolate infection and prevent it from spreading to surrounding tissues.

Abscesses may occur in different locations, including:

• Subphrenic (below the diaphragm)
  
  

• Pelvic abscess
  
  

• Liver abscess
  
  

• Abscess near the intestines or appendix
  
  

The location of the abscess often determines the symptoms and treatment approach.

Symptoms

Symptoms may vary depending on the location and size of the abscess.

Common symptoms include:

• Persistent fever
  
  

• Abdominal pain or tenderness
  
  

• Nausea and vomiting
  
  

• Loss of appetite
  
  

• Fatigue and weakness
  
  

• Abdominal swelling or discomfort
  
  

• Difficulty passing stools in some cases
  
  

In patients recovering from abdominal surgery, persistent fever may be an important warning sign.

Causes

Intra-abdominal abscess usually develops as a complication of another abdominal condition.

Common causes include:

• Appendicitis
  
  

• Perforated stomach or intestinal ulcers
  
  

• Infection after abdominal surgery
  
  

• Pancreatitis
  
  

• Trauma to abdominal organs
  
  

• Leakage from intestinal surgery
  
  

• Inflammatory bowel disease
  
  

Infections from these conditions can spread within the abdomen and form abscesses.

Risk Factors

Factors that increase the risk of intra-abdominal abscess include:

• Recent abdominal surgery
  
  

• Ruptured appendix
  
  

• Intestinal perforation
  
  

• Pancreatic infections
  
  

• Weakened immune system
  
  

• Diabetes
  
  

Careful monitoring after abdominal surgery helps detect complications early.

Diagnosis

Doctors diagnose intra-abdominal abscess through clinical evaluation and imaging tests.

Diagnostic investigations may include:

• Blood tests to detect infection
  
  

• Ultrasound of the abdomen
  
  

• CT scan of the abdomen (most accurate test)
  
  

• MRI in selected cases
  
  

• Diagnostic aspiration of fluid
  
  

Imaging helps determine the size and location of the abscess.

At Moolchand Hospital Delhi, advanced imaging technology allows rapid detection of abdominal infections.

Treatment

Treatment focuses on controlling infection and removing the pus collection.

Antibiotic Therapy

Broad-spectrum antibiotics are used to treat bacterial infection.

Image-Guided Drainage

Doctors may insert a catheter under ultrasound or CT guidance to drain the abscess.

Surgical Drainage

In severe cases or when drainage procedures are not effective, surgery may be required.

Treatment of the Underlying Cause

Managing conditions such as appendicitis or intestinal perforation is essential to prevent recurrence.

Early treatment significantly improves recovery.

Possible Complications

If untreated, intra-abdominal abscess may lead to serious complications such as:

• Sepsis
  
  

• Spread of infection to other organs
  
  

• Intestinal obstruction
  
  

• Organ failure
  
  

Prompt diagnosis and treatment help prevent these complications.

Prevention

Preventive measures focus on early treatment of abdominal infections and careful postoperative care.

Helpful steps include:

• Prompt treatment of appendicitis or abdominal infections
  
  

• Careful monitoring after abdominal surgery
  
  

• Maintaining good hygiene and nutrition
  
  

• Regular medical follow-up for chronic digestive conditions
  
  

Early intervention helps prevent abscess formation.
