摘要

Background

Adult small-bowel intussusception (ASI) is a rare condition with pathological etiologies in most patients. Previously, surgical intervention was the primary treatment modality; however, the introduction of balloon-assisted enteroscopy (BAE) has allowed preoperative BAE in some cases to confirm the leading point, thereby guiding management and reducing surgical need. In this study, we investigated whether the introduction of BAE has altered the diagnostic and therapeutic strategies for ASI by retrospectively analyzing and comparing the clinicopathological features of patients before and after its introduction.

Methods

Fifty-three patients with ASI, initially diagnosed via abdominal computed tomography scanning at Korea University Guro Hospital from 2000 to 2023, were included in our study. Patients were grouped based on double-balloon enteroscopy (DBE) usage, and clinicopathological outcomes were compared retrospectively.

Results

Of the 53 patients, 38 (71.7%) had enteroenteric-type intussusception and 15 (28.3%) had enterocolic-type intussusception. Among the patients with enteroenteric-type intussusception, 15.8% had a malignant cause, whereas in the enterocolic type, 60% had a malignant cause (p = 0.001). Of 38 patients with enteroenteric ASI, 15 (39.5%) underwent preoperative DBE. The surgical resection rate was significantly lower in the DBE group (40%) than in the non-DBE group (73.9%) (p = 0.037). Pathological diagnoses of patients who underwent surgical resection without preoperative DBE revealed 17.6% malignancies and 82.4% benign causes, including idiopathic intussusception (four cases) and Peutz–Jeghers syndrome (two cases). No morbidity, mortality, or recurrence was observed.

Conclusion

Preoperative BAE is a valuable diagnostic and therapeutic modality for ASI, particularly in cases of low-grade small-bowel obstruction, reducing surgical resection rates in most ASI cases. The introduction of the BAE has significantly improved ASI management, achieving high successful reduction rates and few surgical interventions. BAE should be considered a first-line diagnostic and therapeutic tool for ASI management.
