A review of intussusception cases involving failed pneumatic reduction and re-intussusception

Abstract

© 2016 TJTES. BACKGROUND: The aim of the present study was to evaluate cases in which intussusception was unsuccessfully treated with pneumatic reduction (PR), and intussusception recurred following PR. METHODS: The medical records of 401 patients who presented with intussusception between 2003 and 2014 were retrospectively analyzed. Included were 61 patients, 20 of whom underwent unsuccessful PR (Group 1), and 41 of whom experienced intussusception recurrence following PR (Group 2). Treatment and outcome were summarized. RESULTS: In Group 1 (mean age: 14.2 months; range: 2.5 months–6 years) surgery was indicated due to PR failure in 15 patients, and perforation occurred during PR in 5. In these 5 patients, age was under 1 year (range 6–9 months) and mean time to presentation was 3 days (range 2–4). During laparotomy, pathologies were noted: mesenteric lymphadenopathy (LAP) and/or Peyer’s patch hyperplasia was observed in 15 cases, Meckel’s diverticulum in 5 cases. In Group 2 (mean age: 20 months; range: 3 months–6 years), intussusception developed after successful PR in 41 patients, most frequently within the first 24 hours (21.51%). Of the 41 patients, recurrent intussusception (RI) was treated with PR in 36, and laparotomy in 5. Operative findings were mesenteric LAP in 4 and polyp in 1. CONCLUSION: PR is effective for the treatment of intussusception and recurrences. Delayed presentation reduces the success rate. In the event of failure, a lead point is usually encountered at laparotomy.
