Pathway Overview
13 steps
Algorithm Steps
13 total
01Start 02Action Classify Timing of Recognition
Timing affects management
- INTRA-PROCEDURAL: Seen during colonoscopy
- IMMEDIATE: <4 hours post-procedure
- DELAYED: 4-24 hours post-procedure
- LATE: >24 hours post-procedure
- Earlier recognition = better outcomes
03Action Assess Size and Location
Determines management approach
- SIZE: <1cm vs 1-2cm vs >2cm
- LOCATION: Right colon, transverse, left, rectosigmoid
- TYPE: Intramural, transmural, retroperitoneal
- MECHANISM: Mechanical vs barotrauma vs thermal
- Bowel prep quality (contamination risk)
04Decision Signs of Peritonitis?
Determines urgency
- Diffuse abdominal tenderness
- Rebound, guarding
- Hemodynamic instability
- Sepsis signs
05Warning EMERGENCY SURGERY
Immediate laparotomy indicated
- Generalized peritonitis
- Sepsis/hemodynamic instability
- Delayed diagnosis >24h
- Failed endoscopic closure
- Large perforation >2cm
- Poor bowel prep
06Action Surgical Options
Based on findings and patient status
- PRIMARY REPAIR: Clean field, minimal contamination
- RESECTION + ANASTOMOSIS: If viable bowel, minimal contamination
- RESECTION + STOMA (Hartmann's): Contamination, unstable patient
- DAMAGE CONTROL: Severely septic, second look planned
- Laparoscopic approach if stable and expertise
07Action Intraoperative Decision Factors
Guide surgical approach
- FAVOR PRIMARY REPAIR/ANASTOMOSIS:
- - Minimal contamination
- - Stable patient
- - Good tissue quality
- FAVOR STOMA:
- - Feculent peritonitis
- - Hemodynamic instability
- - Significant comorbidities
- - Delayed presentation
08Action Post-Operative Care
Recovery and monitoring
- ICU if septic
- Continue IV antibiotics (5-7 days if complicated)
- NGT if ileus
- Advance diet when bowel function returns
- Monitor for anastomotic leak if performed
- Stoma teaching if applicable
09Outcome Outcomes
Prognosis and follow-up
- Mortality: 5-25% (higher with delay)
- Endoscopic closure success: 70-90%
- Stoma reversal rate: 70-80%
- Follow-up colonoscopy for polypectomy completion
10Decision Recognized During Colonoscopy?
Endoscopic closure opportunity
11Action Attempt Endoscopic Closure
If expertise available and criteria met
- Good bowel prep
- Small defect <1-2cm
- Visible edges
- OPTIONS:
- - Endoclips (through-the-scope)
- - Over-the-scope clip (OTSC)
- - Endoscopic suturing
- Mark site for surgery if fails
12Decision Successful Closure?
Assess completeness
13Action Conservative Management
Close monitoring required
- NPO, IV fluids
- IV antibiotics (broad-spectrum)
- Serial abdominal exams
- CT if clinical deterioration
- Low threshold to operate
- Duration: 24-72 hours
- Path rejoins step 08Shared downstream outcome
- Path rejoins step 06Shared downstream outcome
- Path rejoins step 06Shared downstream outcome
