Intraoperative Enteroscopy – Diagnostic & Therapeutic
Intraoperative enteroscopy is an advanced small-bowel endoscopic procedure performed during surgery to directly examine portions of the small intestine that may be difficult to evaluate with conventional endoscopy.
The enteroscope is introduced during an operative procedure to help locate and evaluate a suspected small-bowel abnormality. It can provide both diagnostic information and, when appropriate, therapeutic endoscopic treatment during the same surgical setting.
This specialized approach may be considered in carefully selected patients when other investigations have not adequately identified or treated the source of a small-bowel problem.
Conditions
Intraoperative enteroscopy may be considered for selected small-bowel conditions, particularly when direct surgical and endoscopic assessment is required.
- Unexplained or recurrent small-bowel bleeding
- Small-bowel lesions requiring direct visualization
- Abnormalities that remain undiagnosed after conventional investigations
- Selected polyps, tumors or mucosal lesions of the small intestine
- Small-bowel conditions requiring combined diagnostic and therapeutic management
- Selected cases where surgical exploration is already being undertaken
Symptoms
Symptoms leading to evaluation may vary according to the underlying small-bowel condition and can include:
- Recurrent or unexplained gastrointestinal bleeding
- Black or tarry stools or visible blood loss
- Unexplained iron-deficiency anemia
- Persistent or recurrent abdominal pain
- Unexplained weight loss
- Persistent gastrointestinal symptoms with inconclusive previous investigations
- Abnormal findings identified on capsule endoscopy or imaging
Causes
The underlying cause depends on the small-bowel condition being investigated. Intraoperative enteroscopy may be used when a suspected abnormality requires direct assessment during surgery.
- Small-bowel vascular lesions causing bleeding
- Small-intestinal polyps or tumors
- Inflammatory or ulcerative small-bowel lesions
- Structural abnormalities of the small intestine
- Persistent or recurrent bleeding with an undetermined source
- Other small-bowel abnormalities requiring intraoperative endoscopic assessment
Treatment
Intraoperative enteroscopy is performed in coordination with the surgical team. The small intestine is examined using an enteroscope, allowing the gastroenterologist to identify lesions and perform selected endoscopic interventions when clinically appropriate.
Depending on the findings, the procedure may allow:
- Direct visualization of the small-intestinal mucosa
- Localization of an otherwise difficult-to-identify bleeding source
- Targeted biopsy of suitable lesions
- Endoscopic treatment of selected bleeding lesions
- Removal of appropriate polyps or lesions when feasible
- Assessment of the small bowel during an ongoing surgical procedure
- Combined diagnostic and therapeutic management in selected cases
The exact approach depends on the surgical procedure, suspected lesion, previous investigations and the patient's overall clinical condition.
Prevention & Follow-Up
Follow-up after intraoperative enteroscopy is guided by the underlying diagnosis, the surgical procedure and any endoscopic treatment performed during surgery.
Helpful measures include:
- Follow the surgical and post-procedure care instructions provided by your medical team.
- Take prescribed medicines as directed.
- Attend follow-up to review biopsy or pathology results when samples are obtained.
- Complete recommended blood tests, imaging or further endoscopic evaluation when advised.
- Report significant bleeding, persistent vomiting, fever, severe abdominal pain or worsening symptoms promptly.
- Continue appropriate treatment and surveillance for the underlying gastrointestinal condition.
Further care is individualized according to the findings, treatment performed and the patient's recovery after surgery.
