Name of the Procedure:

Duodenal Intubation and Aspiration, Diagnostic, Includes Image Guidance, Collection of Multiple Fractional Specimens with Pancreatic or Gallbladder Stimulation, Single or Double Lumen Tube, Includes Drug Administration

Summary

Duodenal intubation and aspiration is a diagnostic procedure where a flexible tube is inserted through the mouth into the duodenum to collect fluid samples. These samples are often analyzed to diagnose various pancreatic and gallbladder conditions. The procedure may involve the administration of drugs and the use of imaging for accurate tube placement and sample collection.

Purpose

This procedure is used to assess and diagnose problems related to the pancreas and gallbladder. It helps in detecting infections, blockages, and other abnormalities by collecting and analyzing fluid specimens. The expected outcome is an accurate diagnosis that can guide further treatment planning.

Indications

• Unexplained upper abdominal pain
• Jaundice or abnormal liver function tests
• Suspected pancreatic or gallbladder diseases
• Persistent digestive problems despite treatment
• Abnormal imaging results suggesting pancreatic or gallbladder issues

Preparation

• The patient may need to fast for 8-12 hours before the procedure.
• Adjustments to medications, particularly blood thinners, may be required.
• Pre-procedure diagnostic tests might include blood work and abdominal imaging.

Procedure Description

1. The patient is usually sedated to ensure comfort.
2. A flexible tube (single or double lumen) is inserted through the mouth and advanced to the duodenum.
3. Image guidance, such as fluoroscopy, ensures correct placement of the tube.
4. Drugs may be administered to stimulate the pancreas or gallbladder.
5. Multiple fractional fluid samples are collected from the duodenum.
6. The samples are then sent to a laboratory for analysis.

Duration

The procedure typically takes between 30 to 60 minutes.

Setting

This procedure is typically performed in a hospital, endoscopy suite, or specialized outpatient clinic.

Personnel

• Gastroenterologist or specialized physician
• Nurses or endoscopy technicians
• Anesthesiologist or sedation nurse (if sedation is used)

Risks and Complications

• Common: Sore throat, mild abdominal discomfort
• Rare: Bleeding, infection, perforation of the gastrointestinal tract, adverse reactions to sedation or drugs used during the procedure

Benefits

The procedure provides valuable diagnostic information that can lead to an accurate diagnosis and appropriate treatment plan. Benefits are typically realized within days as test results return.

Recovery

• Patients may need to rest until the effects of sedation wear off.
• Mild discomfort or a sore throat might be experienced.
• Normal activities can usually be resumed the next day.
• Follow-up appointments may be scheduled to discuss test results and further treatment.

Alternatives

• Endoscopic Retrograde Cholangiopancreatography (ERCP)
• Magnetic Resonance Cholangiopancreatography (MRCP)
• Non-invasive imaging techniques like CT or MRI scans

Each alternative has its own pros and cons in terms of invasiveness, diagnostic accuracy, and potential risks.

Patient Experience

During the procedure, patients will be sedated and should feel little to no discomfort. Afterward, they may experience a sore throat and mild abdominal symptoms, which are typically managed with over-the-counter pain relief and rest.
