Stasis of intestinal contents is a proposed mechanism for intestinal fecalith formation [1,2]. Obstruction and perforation requiring surgical intervention are reported in the literature as consequences of stercoral ulcers at the stone bed [2–4]. We present the case of an impacted anastomotic site fecalith removed after needleknife stricturotomy treatment of the mucosa (●" Video 1). A 71-year-old woman with a 41-year history of Crohn’s disease complicated by two small-bowel resections in 1978 presented with a complaint of right lower quadrant pain, loose stools, and a prior diagnosis of a “mass” in her small bowel since 2012. She denied any weight loss, night sweats, fevers, or nonsteroidal antiinflammatory drug use. Colonoscopy identified a fecalith occluding the neoterminal ileum lumen (●" Fig.1). A 3-cm Roth net (US Endoscopy, Mentor, Ohio, USA) was used to try to pull the fecalith out, but multiple attempts at this were unsuccessful as the net continued to slip off the fecalith (●" Fig.2). Next, a 5-mm needle-knife (Boston Scientific, Natick, Massachusetts, USA) was loaded into the colonoscope and used to perform a stricturotomy on the luminal side of the anastomosis mucosal wall (●" Fig.3). Once the mucosal wall was cut, a reusable endoscopic basket (Boston Scientific, Natick, Massachusetts, USA) was used to retrieve the stone (●" Fig.4). The stone was withdrawn into the patient’s rectum, and after bearing down she passed the 3.8×3.6-cm stone as a bowel movement. The colonoscope was reinserted into the colon and advanced to the terminal ileum, where clips were placed along the cut mucosal wall (●" Fig .5).
