&lt;b&gt;&lt;i&gt;Introduction:&lt;/i&gt;&lt;/b&gt; Intussusception is a rare condition in adults. A pathological lesion is usually found with a significant percentage of malignancy. The optimal treatment is still not universally clear. &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; This is a retrospective review of adult patients with a diagnosis of intestinal intussusception and surgically treated at our institution from January 2009 to December 2018. Clinical, operative, and histological details were collected and analyzed. &lt;b&gt;&lt;i&gt;Results:&lt;/i&gt;&lt;/b&gt; A total of 26 cases, 16 males and 10 females, were diagnosed with surgically proven intussusception during the 10-year period. The mean age was 45 years (range 21–70). Using ultrasound and/or computed tomography as imaging study, the preoperative diagnosis was made in 21/26 (81%) patients. Five intussusceptions were discovered only upon exploratory laparotomy for intestinal obstruction. There were 19 (73%) cases of enteric and 7 (27%) cases of colonic intussusceptions. All patients underwent surgical exploration. Intestinal resection with immediate anastomosis was the technique of choice for most patients. A single patient underwent stoma for peritonitis secondary to intestinal perforation. An organic cause has been systematically revealed, and no idiopathic intussusception was detected. Etiology was malignant in 9 (35%) cases. &lt;b&gt;&lt;i&gt;Conclusion:&lt;/i&gt;&lt;/b&gt; Adult intussusception should be considered in any patient with subacute abdominal pain. Considering the high rate of malignancy, intestinal resection without attempting reduction is highly recommended for colonic intussusceptions. However, a more selective approach can be adopted for enteric intussusceptions.
