Management of Colocolic Intussusception in Adults

Surgical resection without attempted reduction is the definitive management for colocolic intussusception in adults due to the high risk of underlying malignancy (particularly in colocolic types), and reduction should be avoided to prevent potential tumor dissemination.

Diagnostic Approach

Contrast-enhanced CT (CECT) of the abdomen is the diagnostic modality of choice, with 88.5% diagnostic accuracy in identifying intussusception and associated lead points 1. Look specifically for:

  • The characteristic "target sign" or "sausage-shaped" mass
  • Identification of a pathological lead point (present in 44.84% of cases)
  • Signs of bowel obstruction or ischemia
  • Tumor characteristics if present

Key Clinical Context

Adult colocolic intussusception fundamentally differs from pediatric cases:

  • Malignancy risk is substantially elevated in colocolic intussusception compared to other types 1
  • Only 29 out of 1,920 adult cases underwent attempted reduction in a large systematic review 1
  • Colocolic type represents 16.82% of all adult intussusceptions and carries the highest malignancy association 1
  • Abdominal pain is the presenting symptom in 86.23% of cases 1

Surgical Management Algorithm

For Resectable Disease:

Primary oncologic resection is mandatory 1, 2:

  • Perform en-bloc resection without attempting reduction
  • Include appropriate lymph node dissection following oncologic principles
  • Left hemicolectomy for descending colon involvement 2
  • Right hemicolectomy for ascending colon involvement 3
  • Laparoscopic approach is acceptable in selected cases 3

Rationale: Attempted reduction risks tumor dissemination and adversely impacts oncologic outcomes 1, 4. The systematic review of 1,902 patients demonstrated that surgical resection without reduction remains the cornerstone specifically because 98.3% of cases were associated with pathological lead points 1.

For Obstructing Lesions:

If the patient presents with complete obstruction and is a surgical candidate:

  • Emergency surgical resection remains first-line for colocolic intussusception
  • Consider SEMS (self-expanding metal stents) as bridge to surgery only for left-sided malignant colonic obstruction without intussusception 5

Critical caveat: The guideline evidence for SEMS 5 addresses malignant colonic obstruction generally, not specifically intussusception. Given the mechanical nature of intussusception and malignancy risk, stenting is not appropriate for colocolic intussusception itself.

For Non-Resectable/Palliative Cases:

This scenario is rare in colocolic intussusception but if present:

  • Diverting colostomy may be considered 5
  • SEMS placement has limited role due to mechanical intussusception
  • Focus on symptom management

Common Pitfalls to Avoid

  1. Do not attempt reduction before resection in adult colocolic intussusception - this risks tumor seeding and compromises oncologic outcomes 1, 4

  2. Do not apply pediatric management principles - adult intussusception requires surgical resection due to the 44.84% rate of pathological lead points 1

  3. Do not delay surgery for extensive workup - once diagnosed on CT, proceed to surgical planning, especially if obstruction or ischemia is present 2

  4. Do not perform limited resection - oncologic principles with adequate margins and lymph node dissection must be followed 1, 2

Postoperative Considerations

  • Temporary diversion (colostomy) may be warranted depending on bowel condition and patient status 2
  • Ensure clear resection margins on pathology
  • Two-year follow-up shows favorable outcomes with appropriate surgical management 2
