A previously healthy 74-year-old woman with no relevant family medical history was referred to our department to investigate a jejunojejunal intussusception incidentally diagnosed in an abdominal ultrasound performed for evaluation of self-limited episodes of abdominal pain and vomiting. To further investigate the ultrasound findings, computed tomography (CT) was performed and revealed a target sign resulting from an extensive jejunojejunal invagination that involved a large edematous jejunal segment and mesenteric blood vessels and leading to proximal dilation of small-bowel loops with air-fluid levels inside (Fig. 1). Due to partial obstruction and absence of an underlying lesion identified on CT, the patient was referred to antegrade single balloon enteroscopy (Olympus SIF-Q180, Japan) that revealed a type 0-IIa (Paris classification) granular lateral spreading tumor, measuring approximately 4 cm and occupying four fifths of the luminal circumference in the proximal jejunum (Fig. 2 , 3). As endoscopic mucosal resection (EMR) was considered high risk, tattooing was performed and biopsy samples were obtained. Histology revealed a tubulovillous adenoma with low-grade dysplasia and foci of high-grade dysplasia. The patient underwent a laparoscopic enterectomy, whose histology confirmed the initial diagnosis. After surgery, the patient remained asymptomatic.





In adult intussusception there is an underlying cause in more than 90% of the cases, with tumors representing the most frequent etiology [1]. Benign and malignant small-bowel tumors are rare and account for approximately 3–6% of all gastrointestinal neoplasms [2]. With the advent of capsule endoscopy and deep enteroscopy (DE), the reported incidence of small-bowel tumors has increased [2]. Although it accurately identifies adult intussusception, CT may be unrevealing in the evaluation of incomplete small-bowel obstruction and small-bowel tumors [1, 3] . In these cases, DE may provide additional diagnostic information [4] . Moreover, DE allows biopsy sampling and therapeutic interventions [2, 3]. Removal of small-bowel adenomas is advisable due to their predisposition for malignancy.

The boundaries of therapeutic enteroscopy are being continuously expanded [4] and include nowadays smallbowel EMR, as described in a recent series [5] . In this case, EMR was considered high risk, given the longitudinal and circular extension of the lesion, which could be associated with a high rate of incomplete resection, perforation, or delayed stenosis. Hence, laparoscopic surgery was considered a safer therapeutic option.
