Internal intussusception is a functional rectal disorder. Surgery is indicated for patients with solitary rectal ulcer syndrome or circular prolapse, leading to significant symptom improvement.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Functional Bowel Disorders

Background:

  • Debate exists regarding internal intussusception as a functional disorder.
  • Understanding its specific symptomatology is crucial.

Purpose of the Study:

  • To define the symptomatology of internal intussusception.
  • To assess the role of defecography in diagnosis and management.
  • To evaluate surgical outcomes for internal intussusception.

Main Methods:

  • Retrospective review of 37 patients undergoing rectopexy for internal intussusception.
  • Assessment of co-existing solitary rectal ulcer syndrome (SRUS) and anterior rectal wall prolapse.
  • Defecography to evaluate rectal prolapse and pelvic floor function.

Main Results:

  • 26 patients (70%) became asymptomatic post-surgery.
  • Significant improvement observed in patients with SRUS and circular prolapse (P < 0.001).
  • Poorer outcomes noted in patients with anterior rectal wall prolapse (P < 0.001).

Conclusions:

  • Internal intussusception is a distinct functional rectal disorder.
  • Defecographic findings and SRUS presence are key surgical indicators.
  • Normal pelvic floor function during straining is essential for successful surgical outcomes.
