Pathway Overview
16 steps
Algorithm Steps
16 total
01Start 02Action Initial Assessment
History and examination
- Non-judgmental approach essential
- Object type, size, shape
- Duration since insertion
- Prior extraction attempts
- Abdominal pain/tenderness
- Signs of perforation/sepsis
- Mental status (rule out body packing)
03Action Imaging Studies
Assess object and complications
- Abdominal X-ray (KUB): Location, number, type
- CT if perforation suspected
- Look for: Free air, object location
- Above vs below rectosigmoid junction
- Multiple objects possible
- Document for medicolegal purposes
04Decision Signs of Perforation?
Determines urgency
- Free air on imaging
- Peritonitis on exam
- Sepsis/shock
05Warning EMERGENCY LAPAROTOMY
Perforation requires surgery
- Exploratory laparotomy
- Repair perforation or resection
- Remove foreign body
- Washout
- Stoma if significant contamination
06Action Post-Extraction Assessment
Evaluate for injury
- Rigid/flexible proctosigmoidoscopy
- Assess for mucosal injury
- Full-thickness injury vs abrasion
- If injury: CT to confirm no perforation
- Document extent of trauma
- Photos if appropriate
07Decision Significant Injury Found?
Determine disposition
08Action Observation/Discharge
No significant injury
- Clear liquids, advance diet
- Pain management
- Stool softeners
- Return precautions
- Psych/social work if appropriate
- Follow-up in 1-2 weeks
09Outcome Outcomes
Statistics and follow-up
- Transanal success: 60-75%
- OR extraction success: 90%+
- Perforation rate: 1-5%
- Recurrence: Address underlying factors
10Action Manage Injury
Based on severity
- Partial thickness: Observation, antibiotics
- Full thickness: Surgery likely
- Sphincter injury: May need repair
- Serial exams for delayed perforation
- Path rejoins step 09Shared downstream outcome
11Decision Object Location?
Determines extraction approach
- Low rectal: Palpable on DRE
- Mid-rectal: Visible on proctoscopy
- High rectal/sigmoid: Above reach
12Action Bedside Transanal Extraction
First-line for low objects
- Local/regional anesthesia
- Lateral decubitus or lithotomy
- Anal dilation with retractors
- TECHNIQUE:
- - Grasp with ring forceps/clamps
- - Create vacuum release (Foley past object)
- - Bimanual abdominal pressure
- Limit attempts (3 max)
- Avoid fragmentation
13Decision Successful Extraction?
Assess outcome
- Path rejoins step 06Shared downstream outcome
14Action EUA + OR Extraction
For high objects or failed bedside
- General/spinal anesthesia
- Full relaxation critical
- Rigid proctosigmoidoscopy
- Better visualization and instruments
- May need laparoscopic assistance
- Transanal + abdominal if needed
15Decision OR Extraction Successful?
Next steps if failed
- Path rejoins step 06Shared downstream outcome
16Action Laparotomy for Extraction
Last resort for retained objects
- Milk object toward rectum
- Combined transabdominal/transanal
- Colotomy if cannot milk distally
- Primary closure if clean
- Avoid proctotomy if possible
- Consider stoma for contamination
- Path rejoins step 06Shared downstream outcome
- Path rejoins step 14Shared downstream outcome
