Colocolic Intussusception in a Child with Pathologic Lead Point Along with Intestinal Malrotation-A Rare Case Report and Brief Review

Colocolic Intussusception in Children: A Case Series and Review of the Literature

Background

Colocolic intussusception is a rare subtype of intussusception mostly caused by juvenile polyps. The treatment of colocolic intussusception caused by other pathologic lead points in children remains poorly understood.

Method

A systematic literature review was performed between January 2000 and June 2021 to characterize the comprehensive treatment of colocolic intussusception in children. This report also included patients admitted to our center between January 2010 and June 2021 who were not previously reported in the literature.

Results

We identified 27 patients in 20 studies in addition to 17 patients from our center for a total of 44 patients (median age, 4.4 years; 52.3% male). The lead point was identified in 40 patients (40/44, 90.9%). The most common lead point was juvenile polyps (19/44, 43.2%). A therapeutic enema was performed in 15 patients with colocolic intussusception caused by juvenile polyps and was successful in 9 patients (9/15, 60.0%). Colonoscopic polypectomy was subsequently performed in 8 patients and was successful in 7 patients (7/8, 87.5%). The other patient had undergone laparoscopic exploration, and no abnormality was found. Subsequently, the patient underwent open surgery. The patients with colocolic intussusception caused by other pathologic lead points almost underwent surgical treatment (15/21, 71.4%), including 13 open surgeries and 2 laparoscopic surgeries.

Conclusion

A therapeutic enema followed by colonoscopic polypectomy is feasible to treat colocolic intussusception caused by juvenile polyps unless the patient has bowel perforation; however, surgery is sometimes needed. For patients with colocolic intussusception caused by other pathologic lead points, open surgery remains the primary treatment.

Colocolic intussusceptions in children: a pictorial essay and review of the literature

Colocolic intussusception is a variation of intussusception that is rarely encountered in pediatric patients and as such can prove to be a diagnostic challenge for both the emergency clinician and radiologist. Knowledge of the presentation and imaging findings in these cases can expedite diagnosis and guide the patient to appropriate treatment. The demographics, clinical symptoms, imaging findings, and eventual surgical and pathologic outcomes of 8 children with colocolic intussusception will be presented in this pictorial essay, with a review of the available literature.
