Ultrasound guided reduction of intussusception with saline and comparison with operative treatment.

BACKGROUND: Reduction of intussusception under ultrasound guidance by saline has become popular in recent years. However, methods, duration of the procedure and causes of failure are not defined. In this study, we reviewed the patients who underwent ultrasound (US) guided saline reduction and compared them with those who were previously managed by operative intervention. METHODS: Patients with severe peritonitis or perforation, those over 3 years or younger than 1 month were excluded. Saline was applied by anus. Entry of saline into the ileum was the main indicator for successful reduction. Dramatic improvement in the clinical findings was considered as an additional sign of successful reduction. No limit was imposed on duration of the procedure. RESULTS: Hydrostatic reduction was successful in 41 out of 51 patients with intussusception. In three patients with partial resolution, hydrostatic reduction was attempted later and total reduction was achieved. No perforation or other complications were seen. In ten cases with reduction failure, one had an ileal lymphoma and another one had a duplication cyst as lead points. CONCLUSION: US guided hydrostatic reduction for childhood ileocolic intussusception is safe and, painless, has a high success rate and avoids radiation exposure risk. Presence of ultrasonographic and clinical changes is the best indicator of a successful reduction. In some cases, a second attempt may be necessary for reduction.

Ultrasound-guided hydrostatic reduction of intussusception with saline: Safe and effective.

PURPOSE: The study was undertaken to assess the efficacy of ultrasound-guided saline enema in reducing intussusception and to determine the role of age and duration of symptoms on this event. METHODS: The case records of patients who were treated for intussusception at our institutions over the past 10 years were retrospectively analyzed. A total of 419 patients were treated for intussusception and 375 of them were included into the study. Patients were excluded if they had symptoms and signs of acute abdominal disease and required surgery as an initial treatment. RESULTS: Hydrostatic reduction was successful in 313 of the 375 patients (83.46%). The procedure-related complication rate was nil. There were 29 episodes of recurrences in 23 patients, and recurrence rates did not differ between patients who responded to hydrostatic reduction and those who required surgery. Younger age [median (range); 11 months (3-108 months) vs. 20 months (1-180 months); p<0.05], rectal bleeding (p<0.01) and long duration of symptoms [mean (range); 1.95 days (1-7 days) vs. 1.44 days (1-10 days); p<0.01] were significantly associated with failed hydrostatic reduction. CONCLUSION: Ultrasound-guided hydrostatic reduction is an easy, safe and effective method for the treatment of intussusception in the absence of acute abdominal findings.
